Introduction This document is intended for use by project managers, designers, Architectural and Engineering (A/E) firms, the United States Army Corps of Engineers (USACE), and other agencies for application on all project designs produced for Schriever Air Force Base (AFB). Because requirements change frequently, this document will be updated periodically by 50 CES/CENM. Please ensure the most current edition of this document is obtained before beginning any design project.

Application This guide is general; some projects may have exceptions to this guide as determined by the 50 CES Project Manager. Each project manager, engineer, interior designer, and architect, both government and commercial shall use sound judgment in applying this guide.

This guide is not to be referenced by construction specifications or drawings but the information contained herein shall be integrated into the construction specifications and drawings by the designers of record.

Military Construction (MILCON) Design-Build projects shall include this guide as a supplement to the Request for Proposal (RFP) in addition to the USACE Design Guide.

Where conflicts are found between this document and any other guidance, bring them to the attention of the 50 CES Project Manager. Only the 50 CES Project Manager may waive requirements of this document.

The requirements stated in this document apply to all projects unless indicated otherwise.

Purpose This guide provides information regarding the design and construction practices required on Schriever AFB. This will reduce the amount of time required for the review and design of projects and ensure consistency and completeness of all designs.

Scope This design guide is a summary of lessons learned from past projects to prevent them from being repeated. We must provide the best possible facilities for our customers keeping in mind our need to maintain these facilities for many years at the lowest possible life-cycle costs. In this effort, we maintain a larger view of the design needs for Schriever AFB.

This is not intended to replace the USACE Design Guide but to supplement it. This does require that the USACE edit out conflicting requirements. Bring all discrepancies to the attention of the 50 CES Project Manager.

Additional guidance can be found on the DLA website: http://www.dispositionservices.dla.mil/index.shtml

Metering When adding, altering, or constructing facilities, the project shall include the installation or upgrade of meters. Guidance including thresholds is included in the following:

UFGS 26 27 13.10 30 – Electric Meters, http://www.dispositionservices.dla.mil/index.shtml

March 2017

UFGS 33 51 13.00 30 – Natural Gas Meters UFGS 33 12 33.00 30 – Water Meters DoD’s “Utilities Meter Policy” dated 16 April, 2013.

A vital component of the Air Force’s energy program is to measure utility usage at the building level by installing advance meters (electric, natural gas, steam, and water) where cost effective, to not only meet federal meter mandates but to allow for informed decisions and improved energy efficiency. Provide utility advance meters for the Air Force that comply with federal mandates as well as DoD’s “Utilities Meter Policy” dated 16 April, 2013.

The AF classifies building-level advance meters into three categories: (see “Utilities Meter Policy” dated 16 April, 2013 for expanded descriptions)

a. Category 1: Required by Congressional mandates (Energy Policy Act of 2005, EPAct05; Energy

Independence and Security Act of 2007, EISA07) on buildings where cost effective.

b. Category 2: Required, in addition to #1 above, to meet the requirements of DoD’s Utilities Meter Policy, reporting energy/water production data or validating certain project savings, and;

c. Category 3: Other meters not required by mandate/policy, but deemed appropriate by Base/

MAJCOM to capture accurate energy/water consumption; i.e., utility reimbursements.

Category 1 - Required Meters: EPAct05, EISA07 and DoDI 4170.11 Compliance Building-level energy and water meters shall be installed where cost effective, using a “savings factor” of 2%. The buildings that meet the cost effective criteria for energy or water meters will be considered “covered buildings.” All Cat 1 electric, gas and water meters installed on covered buildings shall meet the minimum requirements for these types of meters. Steam meters shall be placed at the output of central steam plants.

Covered Buildings: The Air Force has determined that a building is “covered” when there is sufficient quantity of any utility commodity consumed within the building to make installation of building meter(s) cost effective. For energy/water purposes, the term “covered building” is intended to minimize confusion with the term “covered facility” which has been defined by the SecDef as a permanent military installation and its associated geographically separated units (GSU’s). For the Air Force, covered buildings generally are located within a covered facility; AF energy/water consumption is measured at the covered facility level. The AF will manage covered buildings as EISA07, Section 432 covered whereby energy audits, benchmarking, re-commissioning and M&V programs are focused.

All meters required (Cat 1) shall meet the minimum requirements of the Unified Facilities Guide Specifications (UFGS) and have the following capabilities/functionality:

a. 15-minute interval data with 30-days memory

b. LED or LCD display with wireless communication capability

c. Socket mounted / “plug-&-play”

d. Optical port

e. Maximum data functionality; peak, power factor, kVAR, CFM, harmonics

f. Meter types where no UFGS exists (BTU meters for hot/chilled water) shall be “revenue grade” and have capabilities/functionalities a-e, above

Category 2 - Required Meters: DoD Policy, Reporting, Measurement & Verification Energy Meters (electricity, natural gas, steam, hot/chilled water, propane, etc…) will be installed (in accordance with DoD policy) on all buildings that meet the DoD cost effectiveness criteria, where the “savings factor” is increased to 5%. In addition to Cat 1 meters on covered buildings, install other energy meters so as to capture all energy consumed by the covered building.

Water meters (potable and non-potable) shall be installed on buildings that are estimated to consume greater than 3-million gallons annually. Additionally, the following facilities shall be metered for water use:

a. District heat/chiller plants;

b. Dormitories that house greater than 100-persons (smaller dorms can be group-metered);

c. Swimming pools;

d. Fitness Centers (do not include “annexes” unless they consume >3MGals);

e. Landscape irrigation to include golf courses, (separately fed that consume >3MGals);

f. Hospitals (main hospitals / medical campuses or annexes that consume >3MGals);

g. Vehicle wash stations (aircraft, ground transport and NAF)

In addition, install potable water meters or other leak detection devices on main branches of distribution systems to aid in identifying leaks. Finally, water meters shall be installed so as to capture all potable and other fresh water sources (Wells, streams, lakes, etc) for each installation.

Central Plant/System Metering; Steam, Hot Water, Chilled Water, Potable Water, or Electrical Generation:

Central plants shall meter electrical/gas at the input of the plant. Outputs of central plants shall be metered. Individual buildings connected to central steam, hot water or chilled water plants require meters to accurately identify individual building energy use and system losses. (Note: only steam meters at the output of AF owned central plants are required under EISA07 – see above.)

Measurement and Verification (M&V) Metering: Advanced meters shall be installed on all new MILCON, major building renovations (greater than 50% building replacement value or building infrastructure system upgrades which are greater than $200k on a single system), Energy Conservation Investment Program (ECIP) projects, and Energy Savings Performance Contract (ESPC) projects.

Renewable source metering: Electric meters are required on PV and wind sources when the source is rated greater than (or equal to) 75 kilo-watts (kW). Other renewable types can be estimated (GSHPs or PV/wind below 75kw), or involve a 3rd-party meter.

Cat 2 meter requirements shall leverage, to the maximum extent possible, building automation systems or energy management control systems to create accurate “virtual” meters. All physical meters required in

March 2017 this section (Cat 2) shall meet the minimum requirements of the Unified Facilities Guide Specifications (UFGS). All Cat 2 meters, whether “virtual” or physical, must communicate with the AF’s Advanced Meter Reading System (AMRS).

Provide interface with AMR (Automated Meter Reading) network. Building electric meter shall be a solid state advance meter with the following features: All meters required (Cat 1) shall meet the minimum requirements of the Unified Facilities Guide Specifications (UFGS) and have the following capabilities/functionality:

a. 15-minute interval data with 30-days memory

b. LED or LCD display with wireless communication capability

c. Socket mounted / “plug-&-play”

d. Optical port

e. Maximum data functionality; peak, power factor, kVAR, CFM, harmonics

f. Meter types where no UFGS exists (BTU meters for hot/chilled water) shall be “revenue grade” and have capabilities/functionalities 1-5, above

g. Ability to accept digital inputs from natural gas and water meters, Ethernet port, accuracy meeting ANSI C.12.16, TCP/IP communication, Modbus IP protocol

The Siemens 9330 Advanced Electrical meter meets this requirement. Since there are current no BACNet compatible gas and water meters, they will require incorporation of a pulse initiation device to send pulses through the advanced Electrical meter to the EMCS system or possible future AMR network.

Category 3 - Other meters – Not Required Install non-required meters, such as those used for utility reimbursements (AFI 32-1061; Providing Utilities at AF Installations) or capturing process (industrial, mission) or excluded (e.g., simulators) energy consumption. These meters are not required to meet the UFGS unless they will be communicating to the AMRS front-end, in which case they shall meet the requirements of Cat 2 meters.

Advanced Metering Requirement When adding, altering or constructing facilities over 35k SF or reimbursable customers, projects shall include the installation of advanced meters as per AF Civil Engineer Memo on Facility Metering (signed 26 Apr 06). Facility electric meter shall be a solid state advance meter with the following features: non-volatile memory capable of storing 16 parameters for 30 days, ability to accept digital inputs from natural gas and water meters, Ethernet port, accuracy meeting ANSI C.12.16, TCP/IP communication, Modbus IP protocol. Advanced electric meter installation shall include a bypass circuit and disconnect to isolate meter for the future removal and replacement of meters. Meters shall be installed in the main distribution panel (MDP) when possible. Meters shall never be mounted to the transformer housing.

Unless a variation is approved or directed by the government, caisson diameter shall be 24 inches. The top of each caisson shall be sloped only to drain, so that three #3 or greater ties may be placed in the upper 5 inches of each caisson. A more severe beveled top has been used on light pole caissons at Schriever AFB in the past, but these are not desirable for future construction. In addition to below-grade depth, caissons in parking lots shall extend 30 inches above grade, and caissons in other areas shall extend 6 inches above finished grade. Required electrical components shall enter the caisson below grade. Light poles shall be set plumb on a 1-1/2 inch bed of non-shrink grout and securely anchored to each caisson.

Structural Structural Load Criteria: All structural load criteria shall be in accordance with UFC 1-200-01 and

UFC 3-310-01.

Wind Loads: The pressure coefficient of 0.00256 as used in ASCE 7, equation 6-15, shall be replaced with the value of 0.00212. This accounts for an altitude at Schriever AFB of 6,175 ft MSL.

Local Code Requirements: Local values for wind speed, snow load, etc. shall not be used. Only the values found in UFC 3-310-01 are acceptable.

Soil Bearing Capacity: All new building designs, including building additions, shall be based on a soil bearing capacity as determined by an independent testing laboratory from soil boring information. If soil borings are not possible or not deemed necessary by the government, then an assumed value of 2,000 psf shall be used. The use of this prescriptive value is subject to the approval of the government.

Masonry Design: Special inspection shall be assumed in determining the compressive strength of masonry.

Interior Concrete Floor Slabs: All concrete slabs for interior use shall not have entrained air in the mix design.

Traffic Engineering Road Geometry Design Vehicle: The design vehicle for all road geometry on Schriever AFB shall be a WB-67 unless required otherwise.

Parking Lots: Refer to UFC 3-210-02 and the FEP. Unless required otherwise, fire department vehicle access for a building shall be an all-weather surface at least 10 feet wide which allows the vehicle access to within 33 feet of the main entrance of the building from the base road network or parking lot. If a building has more than one main entrance, the main entrance serving the highest occupancy load shall meet these requirements. Other parking lot dimensions shall comply with the FEP. A minimum aisle width of 24 feet may be allowed if approved by the government.

Pavement Markings: Paint striping shall be retro-reflective and per MUTCD. Thermoplastic striping shall be used for crosswalks, hold/stop lines, and turn and merge arrows in lanes of vehicle traffic.

Thermoplastic striping shall be recessed in the pavement so as to be flush with the top of pavement surface. Crosswalk lines shall have a slip resistant surface. Pavement markings and stencils shall be in accordance with CDOT Standard Plans S-627-1, Sheets 1-5.

There are many more codes and references not listed. The designer is responsible to research all applicable codes for each project.

Heating, Ventilating, and Air-Conditioning (HVAC) Base Information The elevation for Schriever AFB is 6,035 feet. Schriever AFB has centralized mechanical systems located in the Central Utility Plant (CUP), building 600. These systems include five 950-ton Chillers and one 500-ton chiller, along with four steam boilers with an output rating of 13,390 MBH each. These systems serve the buildings within the Restricted Area (RA) via an utilidor. Buildings outside the RA utilize a combination of air-cooled chillers, hot water boilers, and/or dx split systems. A combination of Siemens APOGEE and HSQ controls are used base-wide for the Energy Management and Control System (EMCS).

A common concern is a need to address changes in Heating, Ventilation, and Air-Conditioning (HVAC) load along with the mission changes to avoid inadequate performance of HVAC systems. HVAC systems should be designed with simplicity in mind for longevity and ease of maintenance. Long-term maintenance requirements shall be given high consideration in any system designed and installed.

Controls systems should be designed with the maintenance worker in mind.

For all projects involving the modification and/or replacement of any HVAC-related equipment, the designer shall consult with the 50 CES HVAC shop, Automation Control Center (ATCC), and the Electrical shop.

Instructions for accessing design weather conditions for Schriever AFB are contained in UFC 3-400-02.

Whenever possible, all new HVAC equipment shall be ground-mounted, with the exception of exhaust equipment. Minimum manufacturer’s clearances shall be maintained around all equipment to facilitate maintenance and repair. In the absence of manufacturer’s data, working clearances shall be determined based upon space required for maintenance/repair tasks, ie, removal of coils, motor replacement, filter replacement, etc.

All new refrigeration equipment shall be “non-ozone depleting” (e.g. R-134a, R-410a, R-407c) as addressed in paragraph 3.6.1 of AFI 32-7086. If equipment using ozone depleting refrigerant is the best alternative based upon application and/or lack of alternatives, then a waiver with justification may be processed for exemption per the latest version of the Schriever AFB Refrigerant Management Plan.

Scroll chillers are preferred for capacities up to 200 tons, screw chillers for capacities between 200 and 500 tons, and centrifugal chillers for…
