21.2 AFRC Energy Policy 2013.pdf

Air Force Reserve Command (AFRC) Facility Energy Policy (2013)

Governance:

G1: HQ EMSG: HQ AFRC will establish an Energy Management Steering Group (EMSG) to oversee all energy actions. It will be chaired by the Vice Commander. (ref: AFPD 90-17)

G2: HQ PIWG: HQ AFRC/A7 will establish a Provide Infrastructure Working Group (PIWG) to channel information from the HQ Energy Management Steering Group (EMSG) and AFCESA to the Base Energy Managers. The Base Energy Managers will channel the information to the Wing EMSGs.

Normal mode of communication will be from the Command Energy Manager (or representative) to the Base Energy Managers. Requests for data and other information will be along these same communication lines. The respective Base Energy Manager is responsible to back brief the respective chain of command.

G3: EMSG: Each Installation shall establish an EMSG chaired by the Wing Commander or Vice Wing Commander. The EMSG will develop policies to promote energy conservation, cost controls and build an energy conservation culture. (ref: AFPD 90-17).

G4: Working Groups: Installations have the authority to convene different working groups and develop plans to be presented to EMSGs for approval.

G5: Goals (ref: EPACT2005, EO 13423, EISA 2007):

Energy Reduction: Reduce energy intensity (MBTU/SF) 3% per year based on 2003 baseline.

While AFCESA and AFRC are working on specific goals based on each base’s ability to reduce their energy, each base will be compared to this metric in an effort to maximize AFRC’s energy reduction.

Renewables: Meet annual goals for electricity generated with renewables: 5% in FY10-12, 7.5% in FY13 on and 25% by 2025. 50% must be from new sources (after Jan 1999). (ref:

EPACT 2005, 10 USC 2911, EO 13423) This has been established as an Air Force goal, not an individual Command or Base goal by AFCESA.

Building Performance/Sustainability: Energy consumption must be 30% below ASHRAE 90.1-2007 standards. (ref: EPACT 2005)

15% of MILCON and major renovation projects must comply with MOU on sustainability by FY15. (ref: EO 13423) High-Performance Green Federal Buildings. (ref: EISA 2007)

100% achieving LEED Silver certification (SDD memo, 2 Jun 11) Minimum of 20 points in energy and water Program SDD costs at 2% of primary facility cost All S/R&M projects shall use sustainability principles.

Definition for "major renovation" is expanded in the policy letter to include most

S/R&M projects. (ref: AF Policy, Jun 11)

Advanced Utility Meters: Meter all facilities for electricity, natural gas and water when economically feasible by 2012. (ref: EPACT 2005) Add natural gas and steam meters by 2016. (ref: EISA 2007) Consider every facility over 35,000 SF in size and each fence line meter. (ref: new draft AF Meter Policy)

Utility Meter Reporting: Report to HQ annually number of meters required and those installed. (ref: EPACT 2005) Benchmark metered facilities. (ref: EISA 2007)

Energy Star Products: All products for new construction and replacements will be Energy Star rated or FEMP designated products. (ref: EO 13423)

Electric Motors: All electric motors from 1 to 500 HP will be premium energy type. A/C refrigeration equipment will meet minimum SEER requirements. (ref: EPACT 2005).

Solar Hot Water: New and renovated facilities with a hot water requirement will be 30% solar generated if cost effective. (ref: EISA 2007)

Fossil Fuel: Reduce fossil fuel usage in facilities by the following goals (55% by 2010, 65% by 2015, 80% by 2020, 90% by 2025 & 100% by 2030.) (ref: EISA 2007)

Commissioning: Verification and documentation of design/construction criteria, during the period beginning on the initial day of the design phase of the facility and ending not earlier than 1 year after the date of completion of construction. (ref: EISA 2007)

Audits: Audit 25% of facility SF per year in “covered” facilities. Must be “comprehensive” audits for energy and water. (ref: EISA 2007) AFCESA and AFRC agree that due to the small size of AFRC installations, it is best to audit the “whole” installation in one visit, changing the requirement for installations to an audit every 4 years. The audits will be limited to 75% of Base square footage and funded with ‘NRG’ funds. Additional audits or more advance audits may be accomplished but will be funded by AFRC O&M funds via a separate project number. They may be executed at the same time. Audits focused by REMs as well as other independent audits by ESPC contractors, etc. will count toward the audit goal.

Water Conservation: Reduce water intensity (Mgals/SF) by 2% per year from 2007 baseline and 16% by 2015. All new and replacement fixtures and toilets will be water saving. (ref:

EO 13423) Consider the requirements of WaterSense program.

Greenhouse Gases: Reduce greenhouse gas emissions through reduction of energy intensity.

(ref: EO13514)

G6: Operational Deficits: Minimize overall energy costs by reducing consumption in existing facilities and new facilities.

G7: Funding: Funding comes from various sources. ‘NRG’ funds and “ECIP funds are the most used resource at this time. HQ AFRC will coordinate with AFCESA and Bases to acquire funding for the above actions. AFRC may provide O&M funding for some of the actions depending upon the availability of funds and projects. AFCESA has provided approval of mixing O&M funds and “NRG” funds in a single project where “NRG” funds will be used to ensure that the greater energy saving device or equipment is utilized.

G8: Work Schedules: Schedule tasks and equipment operation to minimize utility demand costs.

G9: Establish a HVAC settings waiver committee:

Each base shall establish a waiver committee to process waivers for temperature settings and/or night setback requirements. The committee shall be composed of, as a minimum, BCE, Base Energy Manager, and Operations Branch person (or a person from the base maintenance contract). Other members may be added as the discretion of the committee.

Committee shall develop process for facility managers to request exemptions (temporary and permanent) from the Base temperature settings and night setback schedules (length of time and adjusted temperature settings.) Committee shall administer these waivers and shall have authority to request CE personnel and occupants to act upon their decisions.

The committee may use the attached form or one similar for occupants to submit their requests. The proposed form includes a section for the occupants to report what other efforts that they have made to minimize the effect of the current temperature setting or nigh setback.

G10: Establish no heat/no cool periods:

Due to limitations of some systems, no heat/no cool time periods will be established (mostly because of two pipe systems, there has to be a downtime between the seasons.)

The goal is to allow downtime to change the systems over, obtain energy savings, and to minimize the impacts upon productivity. Recommended outside temp ranges are:

Spring: Night temps greater than 50 degrees for three consecutive days and daytime highs greater than 78 degrees for three consecutive days.

Fall: Night temps less than 50 degrees for three consecutive days and daytime highs less than 74 degrees for three consecutive days.

Base Civil Engineer has discretion to establish that the nighttime or daytime criteria can be the ruling factor rather than both sets of criteria.

Base Civil Engineer has discretion to waive no heat/no cool periods for any building that has four pipe systems and/or an EMCS system.

Philosophy: Provide a time for converting two pipe systems between systems while balancing the energy savings and any lost of production if temperature ranges vary outside of people's comfort zone.

Base Energy Manager Responsibilities:

M1: Base Energy Manager: Each Civil Engineer shall designate a base Energy Manager whose main focus will be energy related matters.

M2: EMSG Briefer: Act as the POC, secretary and main briefer for EMSG. Coordinate all activities of the EMSG. (ref: AFPD 90-17)

M3: Energy Conservation Awareness: Develop and implement an energy awareness program through the EMSG. Publish an installation ’Energy Proclamation’ referencing this policy.

Publish energy conservation goals and techniques. Relate energy conservation to operational readiness. Create, implement, and sustain a healthy energy awareness program. (ref: EPACT 2005 and DOD 4170.11)

M4: Energy Strategic Plan: Review the AFRC Energy Strategic Plan and build a similar plan for your installation. (ref: AFEPPM04-1, AF Energy Strategic Plan)

AFRC has sent the strategic plan to each base. If bases have not already developed their plan, they should do so immediately. The Bases' plan may be the AFRC plan with a supplement for the base.

M5: Audits: Work with Command Energy Manager to program an energy audit at your base every four years with ‘NRG’ funds. (ref: EISA 2007)

M6: Metering: Work with BCE, HQ AFRC metering representative, HQ AFRC project programming personnel and Command Energy Manager to program the initial advance meters required for your installation. (ref: EPACT 2005, DODI 4170.11 & AF Metering Policy)

M7: Projects: Work with BCE & Command Energy Manager to program, design and execute energy projects that are identified by you or the energy audits. Energy Manager will be the POC for other offices within CE that may be involved.

Funding for energy projects may be ‘NRG” funds, ECIP funds, O&M funds, ESPC, UESC funding mechanism or other sources of funds. Specific requirements for each fund type can be obtained from the Command Energy Manager.

M8: Design Reviews: Work with your design section and review projects for energy matters.

Milestones for review are the creation of DD Form 1391s, preliminary and final designs.

M9: Life Cycle Cost (LCC) Analysis: Work with Command Energy Manager to develop LCC’s for projects selected as Energy Projects. Some energy projects identified for O&M funding may not require a LCC.

M10: Reimbursable customers:

Ensure all reimbursable customers are accurately billed, and that all reimbursements are received back to the appropriate commodity accounts. According to Air Staff, the Energy Manager and the Utility Engineer should either be the same person or in close coordination. To accomplish this tasking the Utility Engineer must coordinate with the Resource Flight and FM.

HQ AFRC will provide guidance on relief of certain reimbursable customers that UFCs, AFIs and other guidance indicates are no longer reimbursable such as, MWR CAT C Facilities and AAFES facilities.

M11: Utility Accounts: Work with Command Energy Manager, Resources Flight and FM to budget installation’s utility funds as required from HQ minus reimbursements from customers.

M12: Reporting: Submit AFERS data by the end of the next month or as soon as the data is available. Verify the data is correct and that all utilities have been entered. Work with Command Energy Manager to re-verify data when requested. "Submit" data when directed by Command Energy Manager.

M13: Utility Contracts: Review annually for compliance and to ensure installation is on the best rate schedule. Ensure that contracting, JA and other CE representatives participate. (ref: FAR part 41.241 and AFI 32-1061)

AFCESA has establish a 5 year schedule to assist bases in reviewing contracts. Provide a year's worth of data to AFCESA when requested and provide other support as needed. If savings are identified, work with JA, Contracting and AFCESA to pursue a revised utility contract.

M14: Benchmarking: Keep utility data for Base and individual buildings. (ref: EISA 2007)

Work with command energy manger in development of “Mock billings” for electric and heating fuels. Once system is established, send to various facility managers and base management for awareness and action.

Currently AFCESA has recommended holding off on inputting data into the Energy Star Portfolio until guidance is received from DOD. AFCESA is trying to get base level info input rather than building level data.

M15: Retro-Commissioning: Retro-Commission facilities that are performing below the standard for that type of facility, that have had significant operational changes or renovations, and whose building systems operate inefficiently. Coordinate project with Command Energy Manager for use of ‘NRG’ funds. (ref: LEED for Existing Building Upgrades)

M16: REM: Coordinate efforts with the HQ Resource Efficiency Manager (REM) to meet base energy conservation requirements.

M17: HVAC settings Waiver Committee.

Participate with other members on the waiver committee. Set up meetings as required by the number of submissions. Perform the necessary background research to make recommendations as to disposition of waiver request (i.e. Recommend what facility work may be required, such as modifications to ductwork, etc, or temperature adjustment or night setback adjustment and period of adjustment.)

Base Energy Manager will always follow up on temporary adjustment to temperature setting and/or night setback schedules to make sure they are adjusted back to normal standard after the set period of time.

Any adjustment to temperature settings and night setback schedules will not be approved beyond the normal winter or summer months.

Design and Construction (HQ and Installation Responsibilities):

D1: Right Sizing: Right size facilities for the function to align with the shrinking force structure. Reduce infrastructure 20% by 2020. Ensure any additional SF growth is in line with FOCUS validated shortages.

D2: Sustainable Programming: Program new construction and major renovation projects according to the Air Force Sustainable Design and Development (SDD) Policy. (ref: Policy Ltr, Jun 11)

Sustainable principles, to include Life Cycle Cost-effective practices, will be integrated into the design, development, and construction of all projects.

MILCON project designs will be LEED silver certified with 20 of the LEED credits produced from energy conservation measures.

Major renovations shall also use LEED principles.

LEED Design MOU: http://www.wbdg.org/references/mou.php.

D3: Energy Programming:

Various sources of “energy” funding is available. Two programs, ‘NRG’ and ‘ECIP’ are managed by AFCESA and have specific submittal dates. These dates are not published as a part of this policy but are mandated by AFCESA. Command Energy Manager will forward these submission dates and criteria as they are received.

Program most energy projects identified by audits, base energy managers, REMs and HQ as ‘NRG’ projects per special instructions provided by AFCESA. Command Energy Manager will assist with ACESPM input requirements.

ESPC, UESC and FPI are construction programs that may be sources for funding for energy projects. Special submittal requirements exist and these projects must be coordinated with Command Energy Manager and AFCESA.

D4: Design: Designs shall comply with the standards/goals that are listed in item G5 above.

D5: Project Design Reviews: Ensure all applicable projects are reviewed by the Energy Manager, the Resource Efficiency Manager and other design professionals to ensure appropriate energy conservation measures are incorporated.

D6: Climate Zones: AFRC Bases are located in the following climate zones which affect the standards that should be applied for energy conservation (ref: 2009 International Energy Conservation Code, Chap 3, Table 301.1 May 2009):

Carswell: Zone 3 Dobbins: Zone 3 Grissom: Zone 5 Homestead: Zone 1 March: Zone 3 Marine Minn STP: Zone 6 Niagara: Zone 5 Pittsburgh: Zone 5 Westover: Zone 5 Youngstown: Zone 5

D7: Building Envelope Requirements: Below are the Minimum R values for insulation (ref:

2009 International Energy Conservation Code, Sec 502, Table 502.2.(1) May 2009):

Item Insulation* Roof R-20 Walls R-13 Floors N/A for Zone 3 and below Floors R-10 for Zone 5 & 6

*The minimum is listed here. Designer should view table to choose his particular construction type and zone to determine the exact requirements. Conform to State and local requirements whichever is the most strict requirement.

D8: Heating, Ventilating, and Air Conditioning (HVAC) Systems:

Units will be sized for the load using the Air Force design criteria (ref: UFC 3-410- 01FA, 15 May 2003 Including change 4, January 2010)

2-2.2 Indoor Design Conditions.

2-2.2.1 Cooling. The indoor design temperature for comfort cooling will be 15 degrees F (8 degrees C) less than the 1.0 percent outdoor design temperature, but will not be lower than 75 degrees F (24 degrees C) nor higher than 78 degrees F (26 degrees C). The indoor design specific humidity will not exceed the outdoor design specific humidity; otherwise, the indoor design relative humidity will be 50 percent. The indoor design temperature provided by evaporative cooling or comfort mechanical ventilation will be 80 degrees F (27 degrees C); the above requirements for specific humidity do not apply where evaporative cooling is used.

2-2.2.2 Heating. The indoor design temperature for comfort heating will be 68 degrees F (20 degrees C) in areas with low levels of physical activity and 55 degrees F (13 degrees C) in areas with moderate to high levels of physical activity. The indoor design temperature for freeze protection will be 40 degrees F (4 degrees C). Where the indoor relative humidity is expected to fall below 20 percent for extended periods, humidification may be added to increase the indoor relative humidity to 30 percent.

Condensing boilers, modular units, variable speed drives, variable refrigerant volume systems (VRV), ground source heat pumps and other feasible energy conserving technologies will be considered for each project. Minimum efficiency requirements are as follows (ref: 2009 International Energy Conservation Code, Sec 503 May 2009):

Equipment Type Size Min Eff Air Conditioners, air cooled <5 tons 13.0 SEER Air Conditioners, air cooled >5 & <11 tons 11.0 EER Air Conditioners, air cooled >11 & <20 tons 11.0 EER Air Conditioners, air cooled >20 & <63 tons 10.0 EER Air Conditioners, air cooled >63 tons 9.7 EER Air Conditioners, water cooled <5 tons 12.1 EER Air Conditioners, water cooled >5 & <11 tons 11.5 EER Air Conditioners, water cooled >11 & <20 tons 11.0 EER Air Conditioners, water cooled >20 tons 11.5 EER Warm air furnaces, gas fired any size 80% Et (thermal eff)

D9: Free Cooling: Provide capability to bypass chiller when outdoor air temperatures are low enough to remove high indoor heat load. (ref: 2009 International Energy Conservation Code, Sec 503.2.6 Jan 2009)

D10: Demand Control Ventilation: Demand control ventilation is required for spaces larger than 500 SF and a flow greater than 1,200 CFM. (ref: 2009 International Energy Conservation Code, Sec 503.2.6 Jan 2009)

Ventilation shall be provided by one or more of the following:

Air-side economizer Non-DDC Automatic modulating control of the outdoor air damper A set outdoor airflow CO2 monitoring demand ventilation systems for buildings with highly variable occupancy.

DDC controlled outdoor airflow

D11: Energy Management and Control System (EMCS): EMCS will be utilized in each facility with 10 tons of A/C or more. Provide timers or some type of method to allow occupants to extend the period that is temperature controlled. Contractor shall program night setback as a part of the installation of the EMCS. During setback and times system is not in use, the dampers for outdoor air and exhaust dampers shall automatically close except for periods of “air flushing” if programmed as a part of CO2 removal. (ref: 2009 International Energy Conservation Code, Sec 503 Jan 2009)

Building system shall be laid out with a perimeter zone and at least one interior zone.

Perimeter zone shall extend from the outside walls to 15 feet away from the walls. For buildings with less than a 50 foot long wall, one zone may be used.

Smaller individual units and facilities too small for economical use of EMCS will use programmable thermostats. Contractor shall program the thermostat at time of installation.

D12: Hot Water: Provide hot water for bathrooms and for specific uses (such as feeding establishments). Meet the G5 goals above for solar hot water heating. (ref: 2009 International Energy Conservation Code, Sec 504 Jan 2009)

Use tank-less heating for facilities with less than/equal to 4 restrooms.

Temperature setting for hot water will be 110 degrees. Due to safety and health requirements, water temperature for certain operations such as health and feeding establishments must have 180 degree water. Coordinate the actual water setting considering that some equipment has water heaters to boost the temperature to 180 degrees. Therefore the system temperature may be lowered to 160 degrees or less with the equipment boosting the water temperature to the 180 degrees required. Take into account high demand periods when adjusting the temperature settings.

Hot water pipes will be insulated with at least 1 inch insulation.

Hot water recirculation system(s) will implement a means to shut off the system during low occupancy or low use periods.

D13: Lights: Typically install high efficiency light fixtures in new construction and major renovation projects when replacing fixtures. A lighting study is recommended to be preformed to guide the re-lamping of facilities to ensure lighting is not excessive and to minimize energy consumption.

Use of T-8, 32 or 28 watt fluorescent lamps for administrative areas are acceptable.

Existing T-12 light fixtures are obsolete and should be replaced with T-8, 32 or 28 watt fixtures. Lighting for administrative areas should be designed at a level of 1 watt/SF.

(ref: 2009 International Energy Conservation Code, Sec 505 Jan 2009)

Use switches (remote from the panelboard located at main entrances and other locations) to allow user control of lighting. For facilities larger than 25,000 SF, use the EMCS as a secondary control to turn lights off during unoccupied times. Motion sensors will be utilized in small offices/bathrooms, hallways and other similar locations.

Day-lighting controls for fixtures located within 15 feet of open light sources such as windows and skylights will be utilized. Skylights and light tubes will be utilized wherever feasible.

Utilize emergency lighting with individual back-up batteries (for small applications) or IPS systems in larger buildings. Continuous lighting (24/7) or “night-lighting” shall be kept to a minimum (emergency lighting levels are less than 1 footcandle.)

Warehouses and hangars shall use high output fluorescents (preferably T-5 technology) or induction lighting.

All outside lights shall be controlled by an EMCS system or by astronomical/photo-cell combination controller (ref: ETL 10-18, Attch 1, para 2-2.2 thru 2-3.3.)

Consider LED or induction type lights for exterior applications. (ref: HEL Policy, 12 Jul 12)

Accomplish a Life Cycle Cost analysis to determine the most cost effective lighting type and configuration (ref: ETL 10-18, para 8.)

Compact fluorescent lights may be used in canopies or porches/overhangs that are less than 10 feet above the floor and at doors.

All incandescent bulbs shall be replaced with Compact Fluorescent Lamps (CFLs) (ref: ETL 07-7).

D14: Low Flow Devices: Use WaterSense products. All new water devices shall be limited to a maximum as follows:

Item Flow Rate Toilets 1.28 GPF Urinals 0.5 GPF Showerheads 1.5 GPM

Hand washing faucets 0.5 GPM

D15: Landscape Irrigation: Eliminate the use of potable water for landscape irrigation systems.

Maximize use of Xeriscape techniques with drought-tolerant landscaping.

D16: Cool Roofs: Use of roofs with a lighter color and greater reflectance and lower absorption should be utilized in southern climates. It has been determined by analyzing data that roofs with a darker color, less reflectance and higher absorption should be used in northern climates. The cool roofs lessen the cooling requirements, in northern climates; the heating requirement far outweighs the cooling requirement.

D17: Renewable Energy: HQ AFRC continually works with Bases to determine economical installation of renewable energy projects. Bases should consider small applications of renewable energy with MILCON and O&M projects.

All renewable energy projects must be compatible with the Installation’s function as an Air Force Base. (ref: Encroachment Policy and Reviews) AFRC bases have limited land and all factors such a visibility or possibility of blinding pilots, air space restrictions, land use restrictions and local perceptions should be taken into account before proposing a renewable energy project.

D18: Energy Security: While this is an emerging field, bases should be aware that certain actions can and should be taken to improve the security of the bases utilities. Most of these actions may be O&M measures and not within the scope of energy conservation. However, there may be some activities that fall within the purview of this policy. Energy conservation itself is considered an aspect of energy security (all energy saved improves energy security.)

Operations and Maintenance (HQ and Installation Responsibilities):

O1: Lighting: Maintain lighting levels at the Illumination Engineering Society of North America (IESNA) recommend values. De-lamp over-lit areas to achieve these levels. Control applicable lighting with occupancy/motion sensors. Indoor night-lighting shall be kept to a minimum.

O2: Lights: Incandescent lamps shall be replaced with compact fluorescent lamps.

(ref: ETL 07-7.)

Dimmers shall be replaced with occupancy sensors or switches.

Dimmable fluorescents (T5 Technology) shall be used where dimming is required.

O3: Hot Water Temperature: Comply with D12 above.

O4: Energy Management Systems: Establish, maintain and maximize use of Energy Management and Control Systems (EMCS, SCADA, etc.) to centrally monitor and control utility and building systems. EMCS should be sustainable and non proprietary.

Provide adjustable ranges on thermostats so that occupants can change their setpoint up or down 3 degrees.

O5: Programmable thermostats: Provide programmable thermostats with lockout capability in facility areas where EMCS is not available or applicable. Contractor shall program the thermostat as a part of installation.

O6: Space Temperature Settings: Maintain facility temperatures in accordance with the table below. Due to short cycling of equipment and equipment limitations, the setpoint can vary by 1 or 2 degrees. (ref: UFC 3-410-01FA, 15 May 2003 including change 4, Jan 2010)

Heating Season (max settings)

Administrative Spaces* Occupied: 68 degrees Unoccupied: 55 degrees

Shop Spaces & hangars Occupied: 65 degrees Unoccupied: 55 degrees

Warehouse spaces 55 degrees

Cooling Season** (min. settings)

Administrative Spaces* Occupied: 76 degrees Unoccupied: 85 degrees

Shop Spaces & hangars (when authorized)

Occupied: 76 degrees Unoccupied: 85 degrees

Warehouse Spaces Not cooled.

*Most MWR, AAFES, Commissary, Dormitory, VOQ's, TLF's, Fire Station and other sleeping areas should be cooled and heated to administrative space requirements.

**Some spaces such as communications closets, computer rooms and Flight Simulators require cooling year round and should be set per the equipment manufacturer’s recommendations. When a range of temperature is given, use a number in the middle of the range. In no case will the temperature be set below 70 degrees.

O7: Night Setbacks: Implement night setbacks with temperature setting in accordance with the above chart.

Provide ample time for people to leave at the end of day and for the system to cool/heat the facility in the morning before people arrive.

Provide schedules that match the occupied schedule of the building. If they change to a second shift or work overtime for more than a week, change their schedule. When changing schedules, make the change effective for only the time that the occupants will be working the new schedule.

Certain areas where more than 12 hour occupancy occurs, such as 2 or 3 shift work areas, AAFES, Commissary, multiply shift operations, Security Forces Operations, Flight Line operations, Dormitories, fire station, and other sleeping areas may not be able to be scheduled for setback due to occupancy requirements.

Provide 1 hour timers on/at thermostats for those occasions when people work late.

Deviations to temperature and night setback schedules must be processed using the waiver process and committee in G9 above.

O8: Building Envelope: Caulk and seal cracks and penetrations. Repair weather-stripping around doors and windows. Repair doors and windows to seal properly.

Replace broken glass with energy efficient glass when possible. Single pane glass should be replaced with double pane or coated with low E nano-ceramic film.

O9: Recurring Work Program (RWP): Perform preventive maintenance according to equipment manufacturer’s recommendations. Validate maintenance action sheet (MAS) items to maximize available man-hours.

O10: Motor Controls: Provide and properly control variable frequency drives (VFDs) on motors with large variations in load. In retrofit situations, replace motor with high efficiency model with installation of VFD. Provide soft start on all large motors 100 HP or greater where VFDs are not used.

O11: Seasonal Temperature Reset: Adjust boiler and chilled water temperature for seasonal requirements. Set reheating to minimum standards.

O12: Landscape Irrigation: Reduce the acreage currently irrigated with potable water.

Maximize use of Xeriscape techniques with drought-tolerant landscaping. Keep irrigation to a minimum.

For existing systems, install irrigation controls that measure ground moisture.

Prevent overwatering any part of the installation.

O13: Flushing: Track flushing requirements (location and amount.) When flushing exceeds 1% of the total water usage, investigate the source/cause of the low chlorine levels and submit project(s) to correct situation.

Facilities & their Occupants (User responsibilities):

F1: Facility Manager: Tenants of Installation facilities shall provide a facility manager for each facility. A facility manager may be responsible for more than one facility. Facility manager and alternates shall receive energy training as a part of the training provided by the Civil Engineer.

F2: Energy Advocates: Energy advocates will be utilized wherever possible to augment the energy conservation policy. An Energy Advocate is a person, military or civilian, that has enough interest in the energy conservation efforts to volunteer service to that end.

F3: Dress Code: Allow casual attire during heating/cooling season to support adherence to temperature guidelines.

F4: Personal Computers, Peripherals and Equipment: Institute operating procedures to minimize energy consumption when devices are not in use, such as timed or occupancy sensing power strips.

Turn off monitors and peripherals at end of duty day. Turn off all printers, copiers, scanners and other office equipment at the end of the duty day. Enable energy savings features if available. Due to download requirements the Communications Squadrons have recommended that all CPUs remain on, but logged off during the night.

Set power saving features on computers (this is set on Windows 7 systems and cannot be changed) to make the computer “sleep” after a short period (less than 3 hours) of inactivity.

F5: Lighting: Turn off or have CE disable all unnecessary interior and exterior lighting.

Turn off interior and exterior lighting when they are not needed (especially over night and weekends.)

Request CE install motion sensors in small office and bathroom areas.

Personal or desk lighting shall be fluorescent or LED.

F6: Space Heaters: Use of space heaters by individuals to supplement area heating is restricted.

(ref: AFOSH 91-501)

Most Bases have written procedures for requesting these heaters. When you do have permission to use these, there are certain operational directions in AFOSH 91-501 that should be followed.

Before researching the requirements for these heaters, request your facility manager to submit a work request to evaluate the temperature settings in your area.

Always turn off the unit when not at your desk.

In lieu of space heaters, foot warmers or pads may be an option.

F7: Kitchen Equipment: Minimize use of personal refrigerators, coffee makers and microwaves by consolidating them into common break areas. Full size refrigerators are recommended over the dorm size refrigerators. All appliances must be Energy Star rated.

F8: Space Temperature Settings: For those facilities with thermostats or programmable thermostats, maintain facility temperatures in accordance with item O6 above. The EMCS will be utilized to maintain these temperature settings per O6 above in larger facilities.

Users can request changes to temperature and night setback schedules using the waiver process and committee in G9 above. Users should record their research to determine what other work could be done to fix problem without adjusting the settings, even if the option to do so is not accepted by CE.

F9: Landscape Irrigation: Landscape irrigation shall be kept to a minimum. Do not overwater your area. Report any water leaks immediately.

Special Facilities Responsibilities:

The below special facilities have additional specific guidance (above guidance is applicable as well unless specific guidance is counter to the above guidance.)

Airfield/Ramp Areas:

S1: Hangars: Heat high-bays and hangars with radiant heat (IR) systems. For fuel cell hangars also provide for other air movement requirements.

Door interlocks will be used to deactivate heaters when hangar or bay doors are opened.

Minimize hangar door open time during heating season. During mild weather make sure that heating system is off when the doors are open.

Utilize de-stratification fans in winter to redistribute heated air down to the work area.

When lamps in high-bay lights reach 80% of their useful life (2-5 years depending upon hours of use per day), replace them by group re-lamping to economize equipment and labor costs. Replacement of ballasts at the same time is encouraged.

S2: Taxiway Lighting: Light emitting diode (LED) lighting shall be used for taxiway lighting.

S3: Airfield Lights:

LEDs are not approved for runway lights and some other uses.

Create policy and action plans to operate lights only when necessary:

Daytime: Turn runway and/or taxiway lights on only when required due to increment weather, landings/take-offs, and other specific requirements.

Nighttime: Although runway and/or part of taxiway lights are required to be on while the airfield is operational, make sure that lights are turned off when possible, especially at the end of this nighttime operational period.

S4: Ramp Lighting:

Control aircraft parking ramp lighting to maintain 0.2 vertical footcandles 3 foot above grade during nighttime operations at the far end of the ramp area. (ref: AFI 31-101)

Light poles shall be properly switched/configured to allow individual control so that inactive parts of the ramp area can be turned off when approved by Security Forces.

Use light carts for maintenance purposes.

Turn lights off when daylight is sufficient for security purposes.

Use of control systems are recommended making it easier to turn lights on or off at a single location (most of the time, the Control Tower.) Use photocells to turn lights off during the daytime. Photocell installation should be such that the control system will allow for testing the lights during the daytime for maintenance testing. The test circuit should be set to automatically reset after an hour if it is not turned off.

When lamps in the high mast fixtures (or on top of hangars) reach 80% of their useful life (2-5 years depending upon hours of use per day), replace them by group re-lamping to economize equipment and labor costs. Replacement of ballasts at the same time is encouraged.

MWR:

S5: Lighting: Use compact fluorescent lamps instead of incandescent lamps (ref: ETL 07-7).

Convert incandescent systems on dimmers to either switched or occupancy sensor CFL, LED, or fluorescent systems.

S6: Vending Machines: Vending machine suppliers shall remove the lamps and disconnect ballasts before delivery to the installation. Or, automatic controls (such as Vendor Mizers) shall be used to shut the entire machine off at times when it is not being used.

S7: Snack bars: Snack bars or similar areas have an excess number of vending machines, candy displays and other items that exhaust hot air into the space, requiring cooling 24 hours per day.

MWR personnel should work with CE to provide separate controls and/or cooling systems for these areas. Unoccupied time cooling shall not be set above 80 degrees to keep various items from melting.

The above temperature setting of 80 degrees is for "official" stack bars, not individual snack sales areas that many divisions develop.

S8: HVAC: In no situation shall the facility use “pre-cooling.” “Pre-cooling” is a term used to describe the practice of turning the temperature below the required set point so that the system will run at full force all night providing an over-cooled facility in the morning. If the air conditioning system will not meet the temperature required during lunch and dinner times, request energy study to determine resolution.

Areas with exhaust hoods shall have make up air piped from the outside to limit the amount of conditioned air exhausted through the exhaust hood. Use interlocked controls so that the intake air is turned off with the exhaust hood. Exhaust hoods shall be shut down when not needed.

Computer & Communications Facilities:

S9: Computer rooms: Main-frame computer rooms, rack-mounted computer installations and communications equipment shall have cooling temperatures set per manufacturer’s recommendations. Most computer manufacturers state that computers can operate satisfactorily in temperatures above 80 degrees. Temperatures of 72 to 80 degrees for computer rooms are recommended. In no case shall cooling temperatures be set below 70 degrees.

When computer rooms are renovated, the computers shall be installed such that “hot isles” and ‘cold isles” are utilized. This basically means that the computer shall be arranged so that there will be a row where the back of the computer racks face each other (hot isle) and in multiple row installations, there will be a row where the front of the computer rack face each other (cold isle). Air flow will be optimized to flow into the bottom of the rack and up and out the top of the rack. Contact the base energy manager when the computers are installed accordingly and a project can be established to properly direct the air up through the computer racks and out the top of the hot isles.

Space under the raised floor used for computer room cooling shall be kept obstruction free to allow adequate air flow to all areas of the raised floor. It is envisioned that there will be cables under the raised floor, but care will be taken to route them so that they do not create bundles obstructing the air flow.

S10: Communication closets: Due to the increase in electronic equipment for communication requirements, most communication closets in facilities may require a dedicated air conditioner sized for the heating load. Work with CE to provide a small thru wall or split system for this requirement allowing the building HVAC systems to be set back during unoccupied periods

Flight Simulators:

S11 Flight Simulator Facilities: Due to the multiply use of space in a flight simulator facility, care must be taken to maintain the temperature per this policy for each area: Administrative, computer room and flight simulator. Main-frame computer rooms, rack-mounted computer installations and communications equipment are exempt from the temperature requirements listed above. Most computer manufacturers today state that computers can operate satisfactorily in temperatures above 80 degrees. Temperatures of 75 to 80 degrees for computer rooms are recommended. In no case shall cooling temperatures be set below 70 degrees.

Dormitories and other sleeping areas:

S12. Dormitories and other sleeping areas: Due to the main use of these facilities at night, night setback is not an option. However, setbacks at non-occupied times should be instituted even if it is a manual operation. Have the people cleaning the rooms ensure that the room A/C and heater is setback at least 5 degrees when the room is cleaned and occupant(s) is not present. Individual room thermostats are recommended with a 5 degree up and down variance to provide occupant comfort during sleeping times. Window curtains and shades shall be used to minimize the effects of sun in the room.
