2-1 OVERVIEW

The National Guard has a commitment to the incorporation of sustainable design standards and practices into selected facilities at Truax Field near Madison Wisconsin. This project is being designed in accordance with UFC 1-200-02, High Performance and Sustainable Building (HPSB)

Requirements and will be third party certified via registration with the Green Business Certification

Incorporated (GBCI) for Guiding Principles Compliance certification. In addition to this narrative and the attached Construction Documents and Specifications, refer to the ANG Sustainability

Requirements Scoresheet.

Truax Field and the 115 th

Fighter Wing have been selected to bed down a squadron of 18-PAA F-

35 Fighter Aircraft. The F-35 mission at Truax Field requires new facilities and changes and upgrades to existing facilities and spaces to provide adequate maintenance spaces on base for the Program. The F-35 Specialized 3-Bay Hangar is a new facility that is being submitted to GBCI for consideration.

As a part of this submission, the Sustainability subsections included in this narrative are organized according to UFC 1-200-02, High Performance and Sustainable Building (HPSB) Sections 2-2 through 2-7. This narrative includes documentation required to be submitted to GBCI for review, included “snippets” of the Specifications and cutsheets from various manufacturers that will support the materials and methods that have been and will be used during the Design and Construction process

To comply with Air National Guard (ANG) regulations, the Base at Truax Field issued a DD1391 document as a part of the solicitation for design services. The DD1391 includes the following statements that serve as a description for the Project:

“Description of Proposed Construction: Construct 3-Bay Specialized Hangar to include bays for fuel cell maintenance, enclosed wash rack, and weapons load crew training utilizing conventional design and construction methods to accommodate the mission of the facility. Facilities will be designed as permanent construction in accordance with the DoD Unified Facilities Criteria (UFC) 1- 200-01, General Building Requirements and UFC 1-200-02, High Performance and Sustainable Building

Requirements. The facility should be compatible with applicable DoD, Air Force, and base design standards. In addition, local materials and construction techniques shall be used where cost effective. This project will comply with DoD antiterrorism/force protection requirements per unified facilities criteria (UFC). Special Construction Requirements include installing all required power and

HVAC to accommodate F-35 operations (overhead infrared radiant heat and ducting/power panels for equipment to provide cooling air/power for aircraft). Install fire protection, fall protection, and lightning protection systems adequate for F-35 operations. Facility will be a three-bay fuel cell/wash rack/weapons load trainer with interchangeable bays. Demolish Building 414. Construction phasing shall enable continued maintenance of assigned aircraft.”

This submission is to demonstrate compliance with the DD1391 requirements for the Project

(attachment #10).

2-2 EMPLOY INTEGRATED DESIGN PRINCIPLES

2-2.1 Integrated Design

The project team consists of all designers of record, the Authority Having Jurisdiction (AHJ), in this case the F-35 3-Bay Specialized Hangar, the Design Working Group (DWG), and the

Commissioning Authority.

As a part of the solicitation for Design Services, the Air National Guard included the DD Form 1391 dated, December 13, 2018 (attachment #10), this document states that the facility will be designed in accordance with the DOD Unified Facilities Criteria (UFC) UFC 1-200-02, High Performance and

Sustainable Building Requirements. In response to this requirement, the building will be third party certified via registration with the Green Business Certification Incorporated (GBCI) for Guiding

Principles Compliance certification.

An integrated design charrette was held with the designers of record, the F-35 3-Bay Specialized

Hangar and the DWG from May 28 to June 5, 2020. Meeting Minutes were provided to the DWG for review and input. During the meeting, the goals of the DD Form 1391 and the requirements of

UFC 1-200-02 were discussed and addressed. The Charette Reports are attachments #01 through

#07.

As the project progresses, the team is holding regular design review meetings to re-assess design and construction decisions as they relate to building performance and sustainability. It was determined that periodic meetings would serve this project better than a sustainability correspondence log. Meeting minutes for those meetings will be maintained and distributed to the team for review, comment, and reference. The Design Review Meeting Minutes are attachments

#03, 04 and 05.

Additionally, the design team prepared Type A1-Schematic Design, Type A2-Design Development, Type B1-Design Development and Type B2-Construction Document Project Books as a required deliverable and the project book was also updated at each Type B service phase. For your review, we have attached the B2-Submittal Drawings and Specifications as attachments #08 and #09.

This process ensured the team was kept informed of the owner’s project requirements (OPR), the basis of design (BOD) and any changes occurring as the design process matured through completion. The team utilized BIM software to integrate, coordinate and optimize their designs throughout the project. Microsoft Teams, an online collaboration tool, was utilized to notify the team of design questions, issues, decisions, and direction. See Section 2-2.1.1 Integrated Planning for further description of design communication and meetings.

The transition from design to construction has also been considered. The construction specifications include reference to UFC 01 200 02, the GBCI Technical Guide and the GBCI Project

Information form which will show the Contractor the items for which they are responsible. The UFC

01 200 02 requirements will also be discussed in the pre-bid and construction kickoff meetings.

The team will utilize submittal exchange to inventory, gather, approve and document construction submittals. The design team will provide HPSB guidance to the contractor as construction progresses.

2-2.1.1 Integrated Planning

The project team utilized integrated planning from the start of the project to identify requirements and to establish performance goals for siting, energy, water, materials, indoor environmental quality, and other comprehensive design goals. Design Working Group interviews were held as an integral part of the design charrette.

The project team (all designers of record, F-35 3-Bay Specialized Hangar and DWG, and CxA) held an integrated design charrette to discuss the Guiding Principles and HPSB requirements prior to commencing A1 Schematic Design. During the meeting, the goals of the DD Form 1391 and the requirements of UFC 1-200-02 and Appendix F of ASHRAE 189.1 were discussed. Refer to the meeting minutes. See the Project Book for a description of the sustainability goals (ANG

Sustainability Scoresheet) and facility programming needs.

The F-35 3-Bay Specialized Hangar defined Operation and Maintenance (O&M) goals not included in the DD Form 1391:

• Utilize LED lighting.

• Utilize manual plumbing fixtures for improved O&M.

• Utilize occupancy sensors for lighting wherever possible.

• Specify architectural finishes appropriate to the space/function to increase longevity and ease of maintenance

• Preference use for the use of bolts and welding as primary connection types to make deconstruction easier

• Material choices to allow for a minimum of 60% of the nonhazardous construction and demolition waste material to be diverted from landfills if this building is ever to be deconstructed.

Operation and Maintenance (O&M) costs of the mechanical systems were considered during design and the Life Cycle Cost Analysis (LCCA). However, as reliable values for O&M costs for different system types are not readily available, no savings between system types were assumed.

Maintenance of the systems was considered when determining the preliminary system layouts and designs. The majority of the mechanical equipment is rooftop mounted on the Admin portion of the

Building for O&M efficiency. The ASHRAE 30% energy consumption reduction from ASHRAE 90.1 baseline dictates what lighting system types can be specified. LED is required in order to maximize the reduction; therefore, deconstruction, operation and maintenance are not a factor. Architectural finishes appropriate to the Hangar Bay and Dirty and Clean Restroom Area applications have been specified to increase longevity.

With the demolition of the existing Fuel Cell Maintenance Building, we are expecting that an additional 30% of those existing materials can be recycled. Many of the materials used to construct the new 3-Bay Specialized hangar (more than the required 60%; anticipated up to 80%) will be able to be recycled including the concrete shallow foundations, concrete pads, the structural steel, metal cladding accents, metal studs, copper cabling, vinyl floor tiles, roofing insulation, roofing membrane and the gypsum board. Masonry walls, where used, can be recycled. The ceiling tiles can be saved and reused. Additionally, the asphalt paving in parking lot can be recycled.

Preference for the use of bolts and welding is being specified as the primary connection type where

ANG/WI: F35 3-Bay Specialized Hangar GBCI Project Number: XGFG189002

Page 6 of 122 GBCI Project ID: 1000138090 possible to make deconstruction easier and to increase the likelihood that the steel remains in a reusable condition.

Another meeting was held at the Type B1, 50% design "on-board" meeting to review these requirements and discuss how design changes may affect each other During the Type B2 Pre-Final

Submittal preparation, HPSB design integration was addressed via email, phone calls and ad-hoc meetings and resulting discussion were incorporated into the B2 Submittal.

As the project progresses, the team is holding regular ad-hoc meetings, emails and calls to re-assess design and construction decisions as they relate to building performance and sustainability.

It was determined that periodic ad-hoc meetings, email and calls would serve this project better than a planning log. Meeting minutes for formal meetings were maintained and distributed to the team for review, comment and reference.

2-2.1.2 Evaluation for Design Strategies

The team evaluated several different building layouts, site layouts and building massing

(daylighting) options based on Site (Attachments #06), Indoor Air Quality, Environmental Quality, Energy, Commissioning and Natural Lighting (Attachments #05), Initial Cost and Operation and

Maintenance. Ultimately the best design optimization was chosen as the favored concept option.

This is represented by the Option 1 floor plan and site plan. The team also discussed three HVAC options: chilled water roof top units, geothermal heat pumps, and direct expansion rooftop units with gas heat. An energy model was developed to compare the performances of the three HVAC alternatives alongside installation and replacement costs for the life-cycle costs analysis. Passive strategies for lighting and ventilation were considered and utilized where applicable. The Weapons

Training Hangar will be ventilated via mixed flow inline exhaust fans ducted for low exhaust pick-up in addition to a roof-mounted, direct fired make-up air unit, low intensity radiant heat for supplemental heating, and HVLS fans for cooling and destratification. The Wash Bay Hangar and

Fuel Cell Maintenance Hangar will be ventilated via exhaust fans ducted for low exhaust pick-up with glycol heat recovery, dedicated outdoor air units with glycol heat recovery, gas heat and DX cooling with gas reheat. These (2) hangars are also provided with gas fired humidifiers and low intensity radiant heat for supplemental heat in addition to CCA units ducted with flexible duct connections to provide conditioning to localized fuel cell work. All (3) bays will also be provided with a DX PCA unit to serve the aircraft. The Men’s and Women’s Restroom/Locker Room and tool area will be heated and cooled via split system DX fan coil units with heating water reheat, ventilated via exhaust through an energy recovery wheel in a dedicated outdoor air system providing tempered and dehumidified ventilation air to the fan coil units. The administration support spaces will be served via a packaged rooftop unit with DX cooling and gas heat. This area will get individual zone control via VAV boxes with heating water reheat. Comm rooms will be conditioned by split system heat pumps. The main electrical room will ventilated with louvers on the exterior and heated with heating water unit heaters. The three Hangar Bays will also be partially lit during the day with natural diffused light through clerestory, insulated, translucent panels above the workspace. The

Office area will be partially lit during the day with natural diffused light through clerestory, insulated, translucent panel skylights above the workspace. To help mitigate glare near windows, sunshades have been placed on the exterior of the wall. Other perimeter spaces will receive daylighting through vision glass.

2-2.1.3 Evaluation of the Site

Although the siting of the building was not included in the DD1391, the building had already been sited within F-35 3-Bay Specialized Hangar Master Plan/Installation Development Plan. However, within that pre-determined site, the team brainstormed different building layouts and sighting to maximize the options for aircraft movement. This is represented by the Option 1 floor plan and site plan (attachment #03, 05, 06 and 15).

The Option 1 building orientation is favored because it maximizes frontage to the existing apron for the new hangar bays yet minimizes the amount of apron pavement that will need to be replaced.

This building configuration also provides enough distance from the airfield pavements to maintain safety areas and clear airspace

2-2.1.4 Site Integration and Design of the Building

Site design elements that ensure safe and convenient pedestrian access.

New sidewalks will be constructed to provide safe and convenient access from Mitchell Street and the adjacent parking lot to the main entrance to the facility. The sidewalks were designed to meet

Architectural Barriers Act (ABA) requirements.

Meet the requirements of UFC 3-201-02.

There is no existing irrigation system, and this project does not include the construction of a proposed irrigation system. Potable water will not be used for irrigating new landscaping, other than for turf establishment. There will be only minor site landscaping including turfgrass establishment by seeding due to the proximity to the airfield to limit wildlife attractants. Other plantings and landscape design features are not included and are not part of the base aesthetics or project goals. Minimalist landscaping further supports anti-terrorism/force protection (UFC 4-

010-01) compliance by not having landscape features that could conceal an explosive threat

UFC 3-201-02 Critical Design requirements for planting and irrigation establishment period will be addressed in the project specifications. Section 329200-Turfs and Grasses of the project specifications will include an article on Turf Maintenance, which will require a 1-year warranty and maintenance period, with periodic inspections at the establishment of the turf, substantial completion of the project, and as directed by the Owner's Representative.

Incorporate results of site analysis, in order to design the building, focusing on orientation, configuration and massing.

The base installation development plan/master plan had previously located the 3-Bay Specialized

Hangar in the proposed location. The team evaluated different building layouts, sighting, and roof massing (daylighting) based on Site, Indoor Air Quality, Environmental Quality, Energy, Commissioning and Measurement Verification, Initial Cost and Operation and Maintenance. The F-

35 3-Bay Specialized Hangar goal was to provide the most efficient aircraft movements into and out of the hangars back to the existing apron.

Ultimately the highest rated configuration, or design optimization was chosen as the favored

ANG/WI: F35 3-Bay Specialized Hangar GBCI Project Number: XGFG189002

Page 8 of 122 GBCI Project ID: 1000138090 concept option. This is represented by the Option 1 floor plan and site plan. (Attachments #11, 12, 13, 14 and 15).

The building has been oriented to most optimally satisfy the requirements and goals of the project;

including DWG requirements, and the surrounding site restrictions, while also maximizing energy efficiency and passive solar and daylighting.

The orientation of the building in selected Option 1 (Attachment #15) provides daylighting through windows, skylights and insulated translucent panels.

The three maintenance hangars will offer passive ventilation via frequently open hangar doors. They will also be lit during the day with natural diffused light through clerestory, insulated, translucent panels above the workspaces.

The design team has selected, designed and integrated into the overall building, high performance and sustainable systems (e.g., HVAC, plumbing, water heating systems, lighting systems, control systems, elevators, building envelope and fire protection systems).

Lighting: The Project will utilize LED fixtures throughout and automated lighting controls. Daylighting is offered through the use of insulated, transparent panels and skylights where clear glazing is not required. The use of insulated, transparent panels will be balanced with insulated walls to optimize building envelop performance and daylighting. Skylights were added into the occupied spaces on the South side to allow natural light deeper into these spaces. To help mitigate glare near windows, sunshades have been placed on the exterior of the wall. Other perimeter spaces will receive daylighting through vision glass.

HVAC: The team evaluated three HVAC options: chilled water roof top units, geothermal heat pumps, and direct expansion rooftop units with gas heat for energy reduction, fossil fuel reduction, life-cycle cost and occupant comfort optimization. The energy model allowed the team to evaluate expected energy usage for the different options as well as the impacts of incremental changes to envelope properties and equipment performances.

Plumbing: Water efficiency design decisions will be made according to Chapter 1 of UFC 1-200-

02, meet the requirements of ASHRAE 189.1 Section 6.3.2, which incorporates USEPA

WaterSense-labeled products, 6.4.2 and 6.4.3.

Fire protection: Fire Suppression Systems will be provided via connection to the base-wide potable water distribution system. Reduced-pressure zone backflow preventer (RPZ) will be provided for backflow prevention between the fire suppression systems and the potable water system. The hangar bays will be protected with a single-interlock precaution system and a high expansion foam

(HEF) system. The non-hangar bay spaces within the building will be provided with wet pipe sprinkler system.

Building Envelope: The exterior materials have been carefully considered to accomplish the following goals:

Maintain the architectural harmony being created on the base by several recently completed projects. Materials used on those projects that will also be used in this project include: insulated

ANG/WI: F35 3-Bay Specialized Hangar GBCI Project Number: XGFG189002

Page 9 of 122 GBCI Project ID: 1000138090 metal wall panels, exterior insulated finish systems (EIFS) split faced, colored concrete block masonry with a cast stone coping. All of these materials are proven systems that have performed very well on similar buildings in this same climate for years.

All the exterior materials used in the current design are very durable and will serve the base with average maintenance costs for years to come (50+ years average).

Alternate exterior materials that could have been chosen, such as non-insulated metal wall panels or wood panel cladding, would not provide the same serviceability and durability that the proposed materials will provide.

The project includes energy efficient, double glazed, low-E glazing or translucent wall panels to permit daylighting of interior spaces where vision glass is unnecessary.

The project includes insulated metal doors (man doors and overhead doors).

Furthermore, wall systems at the administrative spaces will be comprised of split-faced, colored concrete masonry units with a cast stone coping and EIFS. Wall systems at the Maintenance

Hangars will be comprised of insulated metal panels. split-faced, colored CMU with a cast stone coping. These systems are economical, recyclable during future deconstruction, energy efficient, and durable while meeting the installation architectural design standards for aesthetic value.

Insulated roof systems will be reflective combination of white PVC membrane roofing.

Promote opportunities for occupants to voluntarily increase physical activity.

Occupants who work in the hangar spaces have standing workstations. The nature of the maintenance work is physical by itself. Occupants have nearby physical fitness centers and running areas as fitness is a requirement of Air National Guard members. Personnel vehicle parking is also located away from the buildings for anti-terrorism reasons and promotes walking to/from vehicles on a regular basis.

2-2.2 Commissioning

. FSB has produced a specification that requires the G.C. to provide a commissioning specialist.

The F-35 3-Bay Specialized Hangar, or AHJ per UFC 01 200 02, wants the Commissioning Firm to be responsible to the owner instead of the General or Prime Contractor for the reason that the

Commissioning Firm could be put in a compromised position working for the contractor which directly conflicts with the requirement that the Commissioning Firm be independent.

The following systems will be commissioned:

Plumbing Systems

DOMESTIC HOT WATER (DHW) SYSTEM

DOMESTIC WATER METER

ANG/WI: F35 3-Bay Specialized Hangar GBCI Project Number: XGFG189002

Page 10 of 122 GBCI Project ID: 1000138090

HVAC Systems (and integral equipment controls)

ROOF TOP UNITS

CCUS

HEAT RECOVERY LOOPS

HEATING WATER UNIT HEATERS

MAKE-UP AIR UNITS

DEDICATED OUTDOOR AIR UNITS

HEATING WATER SYSTEM

BUILDING AUTOMATION SYSTEM (BAS) AND RELATED HVAC CONTROLS

EXHAUST AIR SYSTEMS

Electrical Systems

INTERIOR BUILDING LIGHTING CONTROLS (occupancy / vacancy sensors)

EXTERIOR BUILDING LIGHTING CONTROLS

FIRE ALARM SYSTEM (related to HVAC systems)

Miscellaneous Systems

UTILITY METERING (connections to the BAS)

These additional systems will not be commissioned for the following reasons:

Building envelope systems, components and assemblies to verify the airtightness and thermal and moisture integrity will not be commissioned. The F-35 3-Bay Specialized Hangar has directed only the energy using systems to be commissioned; thermal envelope commissioning is not a goal/requirement of this project. The shop and storage spaces within the building will by their nature require frequent use of overhead doors minimizing the impact that envelope testing could have.

Fenestration control systems: Automatic controls for shading devices and dynamic glazing will not be commissioned because there are none on this project.

Fire Suppression and Alarm Systems will not be commissioned. Life, Health and Safety (LHS) systems are typically not energy using systems. This building is being commissioned for sustainability purposes. The LHS for this project will not be complex. The LHS systems (fire alarm, suppression, MNS) will be fully tested and verified they are operational and fully functional by the certified installers in the presence of ANG maintenance technicians and usually in conjunction with their training requirements as identified in the project specifications. For these reasons, the F-35 3-

Bay Specialized Hangar does not desire the systems to be commissioned as part of this scope.

Process water pumping and mixing systems will not be commissioned because there are none on this project.

Service water heating systems will not be commissioned because there are none on this project.

Renewable energy systems will not be commissioned because there are none on this project; they were not found to be life-cycle cost effective.

ANG/WI: F35 3-Bay Specialized Hangar GBCI Project Number: XGFG189002

Page 11 of 122 GBCI Project ID: 1000138090

Elevator Controls will not be commissioned because there are none on this project.

Security Systems will not be commissioned. There are security systems on this project (door security/magnetic locks/keypads) but they should not be commissioned per the F-35 3-Bay

Specialized Hangar. The construction contractor’s project scope includes installation of the rough-in components, but the ANG (or their specialized vendor under separate contract) installs the security system/devices/final connections, not the construction contractor.

Audio /Visual Systems will not be commissioned because there are none on this project. This equipment is not in the contract.

Communication Systems will not be commissioned. The project does have communication systems

(public address and data/communication drops at certain locations); however, the F-35 3-Bay

Specialized Hangar does not want them commissioned. The public address (PA) system will be independently tested and verified by the vendor. PA system also interfaces with GFGI telephone system; functionality of PA system controls via the telephone system will be verified separately as part of telephone system verification. The communication drops will be roughed-in by the construction contractor, but the ANG will have their communication specialists make those final connections to their system.

2-3 OPTIMIZE ENERGY PERFORMANCE

2-3.1 Energy Efficiency

2-3.1.1 Commercial and Multi-Family High-Rise Residential Buildings

The building design will meet or exceed requirements set out in ASHRAE 90.1-2013 as well as applicable efficiency improvements as called for in ASHARE 189.1-2014. The energy model analysis includes spaces and equipment modeled to these efficiency standards. The efficiency standards will be required as minimums on the equipment schedules included on the design drawings.

Energy Star equipment will be specified where applicable and where included in the project program (versus Government Furnished/Government installed equipment; the Government purchases Energy Star equipment as a standard, where available)

Refer to the HPSB documentation for a list of ENERGY STAR and FEMP – designated Energy

Efficient Products

2-3.1.5 Standby Powered Devices.

Much of the shop equipment only has on/off mode. Fixed electronic equipment does not typically have a low powered standby mode. When equipment has the ability for a standby mode of operation low wattage standby devices will be utilized. Half-switched duplex receptacles are installed throughout the facility as defined by ASHRAE 90.1 that are controlled by the occupancy sensors. The occupancy sensors are controlled and can be scheduled by the central lighting controller. The ANG will need to comply with this requirement for any equipment purchased under separate contracts.

2-3.2 On-Site Renewable Energy

Renewable energy systems were not included in DD Form 1391 authorization / limited scope of work for this project. Nevertheless, life-cycle cost analyses (LCCA’s) were performed for photovoltaics, solar hot water, and geothermal systems.

Photovoltaic system was determined to not be practical for the project. Roof area of new buildings suitable for the installation of photovoltaic panels is limited. LCCA for roof mounted photovoltaic system on available roof area indicates a simple payback of 24 years, which exceeds the 20 year current average life expectancy of photovoltaic systems.

Energy model results were input into geothermal modeling software to determine initial field sizing and performance. This information was utilized during the life-cycle cost analysis to determine initial cost of the geothermal heat pump system. As the geothermal bore field is the mechanical system component with the longest service life, the LCCA duration was selected at 40 years. The

LCCA determined that direct expansion roof top units with gas heat was the lowest cost option over this period. Because of these results, geothermal heat pumps were not recommended for installation.

ANG/WI: F35 3-Bay Specialized Hangar GBCI Project Number: XGFG189002

Page 13 of 122 GBCI Project ID: 1000138090

2-3.2.1 Solar Domestic Hot Water (SDHW)

The Solar Hot Water System Calculator available through the Energy Efficiency & Renewable

Energy website was utilized to evaluate a solar domestic hot water system. The recommended hot water usage rates and equipment efficiencies were input along with the average fuel cost for the state of Wisconsin that available from the DOE. The resulting simple payback for a solar hot water system was 167 years. Given that this timeframe is beyond that of the overall HVAC life-cycle cost analysis, as well as beyond that of the expected average service life for the equipment, installation of a solar hot water system is not recommended.

2-3.3 Metering

The project team has provided individual metering as required by UFC 1-200-02 for water (new), gas

(new), electric power (new). There is no steam supply for this project.

2-4.1 Indoor Water

Water efficiency design decisions will be made according to Chapter 1 of UFC 1-200-02, and meet the requirements of ASHRAE 189.1 Section 6.3.2, which incorporates EPA WaterSense-labeled products. Clothes washing machines will comply with ENERGY STAR program requirements.

2-4.1.1 Indoor Water Metering

An advanced meter will be provided per UFC 1-200-02 for Building-level water metering. Meters are tied to base wide monitoring system (Andover Controls is the contractor/vendor).

2-4.2.1 Outdoor Water- Landscaping proposed irrigation system. Potable water will not be used for irrigating new landscaping. There will not be site landscaping beyond Seeding activities until the turf is established. The south side of the buildings is fully paved. The F-35 3-Bay Specialized Hangar requested concrete edging between the grass and buildings to facilitate/ease maintenance along the perimeter of the buildings. (See Attachment #24)

UFC 3-201-02 Critical Design requirements for planting and irrigation establishment period will be addressed in the project specifications. Section 329200-Turfs and Grasses of the project specifications will include an article on Turf Maintenance, which will require a 1-year warranty and maintenance period, with periodic inspections at the establishment of the turf, substantial completion of the project, and as directed by the Owner's Representative.

The licensed civil design professional is providing the landscape design required for this project.

The project scope includes only turf/grass seeding around portions of the perimeter of building.

This is covered in the civil/site plans and corresponding specifications. Other plantings and landscape design features are not included and are not part of the base aesthetics or project goals as established by the F-35 3-Bay Specialized Hangar. There is also no permanent irrigation system.

Therefore, this requirement is compliant. Minimalist landscaping further supports anti-terrorism/force protection (UFC 4-010-01) compliance by not having landscape features that could conceal an explosive threat.

2-4.2. Outdoor Water Metering proposed irrigation system. Potable water will not be used for irrigating new landscaping, other than for plant establishment. Therefore, outdoor water meters will not be utilized and are not applicable.

2-4.3 Alternative Water

There isn’t any permanent irrigation on this project; therefore, the project is in compliance. Grey water cannot be utilized for latrines and break room nor can it be utilized for any mission activities.

2-4.3.1 Stormwater Management

The project is being constructed in an area that includes existing Building 414 and paved areas.

Much of the existing site consists of impervious area. Under proposed developed conditions, the actual amount of impervious area will be reduced from the existing condition with the addition of green space (turfgrass established by seeding). According to UFC 3-210-10, the definition of

“footprint” consists of all new impervious surfaces associated with the buildings, including both building area and pavement area of associated supporting facilities (such as parking and sidewalks).

"Footprint" does not include existing pavement area to be resurfaced. This project includes the modification of existing impervious surfaces through demolition and reconstructions but overall, the impervious area will be reduced. As a result, there will be a reduction in the post-developed volume and rate of storm water runoff to the existing storm sewer system, which complies with UFC 3-210-

10, but the preparation of further documentation is not applicable.

Pre-Development Conditions:

Impervious Surfaces to be removed = 85,588 sf (Building 414, asphalt parking lot and pavements concrete apron pavement, concrete sidewalk, and combination concrete curb and gutter)

Post-Development Conditions:

Impervious Surface to be constructed= 28,900 sf (building) + 16,301 sf (concrete sidewalk and pavement)+ 239,675 sf (asphalt pavement) = 84,876 sf

2-5 ENHANCE INDOOR ENVIRONMENTAL QUALITY

2-5.1 Ventilation and Thermal Comfort

The Wash Bay hangar and Fuel Cell maintenance hangars will be heated and air-conditioned mechanically and exhausted with low air exhaust for fumes. The Weapons Training hangar will be provided with a direct fired make-up air unit and radiant heat for heating and a de-stratification fan to increase space comfort during peak seasons, this hangar will also be exhausted for fume control.

Additional passive ventilation measures in the clerestory translucent panel were evaluated but non-operable panels were selected due to their height.

2-5.2 Daylighting and Lighting Controls

Daylighting (Light Stanza Software) was modelled for the building throughout the design process resulting in several changes including adding skylights for some of the interior offices and adding shading devices to the exterior windows to control glare. (Attachment #16)

LED lighting with automated controls will be used throughout the facility. Lighting controls were coordinated with the daylight analyses.

Insulated, translucent, panels will be used for natural lighting in the hangar areas of the facility.

Skylights were added into some occupied spaces on the South side to allow light into these spaces.

To help mitigate glare near windows, sunshades have been placed on the exterior of the wall. Other perimeter spaces will receive daylighting through vision glass.

At the interior of the hangar areas, the CMU walls will be painted a light color to assist in the dispersion of natural light that will enter those spaces from the translucent panels above.

Automated lighting controls in accordance with UFC 3-530-01 and ASHRAE 90.1 -2013 will be provided. The system will include a central lighting control network for monitoring and control of the lighting. The lighting control system will be connected to the building management system (BMS).

Typical Office/Admin Areas

In typical office/admin areas, a combination of a wall mounted on/off switch in each office/admin area will be provided with a vacancy sensor in each room to automatically turn off the lighting in the space after the room/area has been vacant for an adjustable time period (30 minutes). HVAC system will also utilize the status of the sensors (via the BMS) to set temps, etc for the rooms. The system will have the capability to perform programmed sweeps within the building. Capability of programmed sweeps to turn off lighting in admin/offices after normal hours will be provided. Daylight sensors shall be provided in rooms exposed to daylight. The network controls will have the capability to dim fixtures based on the available daylight in a space.

All three Hangar Bays will be controlled by individual area. High Bay fixtures will be controlled by manual wall switch with dimming capability. Daylight sensors shall be utilized for daylight provided thru translucent wall panels and Hangar Doors when they are open. The Hangar Bay lighting system

ANG/WI: F35 3-Bay Specialized Hangar GBCI Project Number: XGFG189002

Page 17 of 122 GBCI Project ID: 1000138090 will also be controlled via the BMS with programmable software to control lighting by automatic and manual on/off command, programmable setting of light levels through dimming, daily/hourly scheduling of the control and light levels by time of day and by tasks being performed in the Hangar

Bay.

Exterior lights will be controlled by photocell that will be tied into the central lighting controller. The central lighting controller will be tied into the BAS system.

2-5.3 Indoor Air Quality

2-5.3.1 Moisture Control

The thermal envelope, including below the concrete slab on grade, will include vapor barriers. The new exterior walls at the hangar bays will be insulated metal panels and split-faced colored CMU with the appropriate vapor barrier. The other areas of the building will be split-faced colored CMU and EIFS with the appropriate vapor barriers. Water and vapor intrusion will be eliminated by these two wall systems. This project will include the installation of a vapor barrier at the entire perimeter of the building, both in the roofing and walls systems. The new concrete floor slab will include the installation of a vapor barrier for interior space humidity control and to protect the non-permeable floor finishes.

Below Slab Vapor Barrier

The Technical Guide requires that the submitter “Review (Step 1) ASHRAE 189.1 Section 8.4.2.”

The reality of this document is that it really gives very little guidance about selecting materials. Step

2 requires the submitter to Utilize Table 3.1 which is a helpful tool if the Product Data actually lists the standards that match the requirements listed in the document.

Path Two is the path that we are following for this submission. Path Two in the Technical Guide supplies an active internet link to several LEED locations where the actual requirements for material selection are defined quite accurately. These are the links that we used to help us select the materials for the Project.
