Compatible DoD Missions

Missions: Sustainability & SecurityEnergy efficiency = Savings = More $$ for War-Fighting

Missions: Home-style Setting & Military-style DisciplineQuality of Life Upgrades = Unit cohesion and more effective

learning/training/living environment for War-Fighters

10-3-12 Net Zero through Emerging Technologies 2

Net Zero Ready vs Net Zero

Federal funds not available for total on-site photovoltaic power system needed to reach Net Zero

Took Marines’ approach: “improvise and overcome”

Designed/built to meet Net Zero if/when additional funds available to complete power system

Much more affordable to retrofit to Net Zero if originally designed as Net Zero Ready

Highly efficient building systems & exterior envelopes, using Whole Building approach

Fulfilling the Missions

Consecutive projects, US Marine Corps Air Ground Combat Center (MCAGCC) Twentynine Palms, CA

Package 9, completed September, 2011 $129 Million Net Zero Ready, awaiting LEED Platinum certification

Original mandate LEED Silver. Team pursued LEED Gold without adding costs or renewable energy re DoD certification policy

At 85% completion, received $20M Energy Enhancement Project grant which funded solar panels

3-4-12 XD Report 4

BEQ Package 9 continued

• Team granted modifications to provide for design/construction of:

PV solar power exterior lightingAdvanced metering (including SCADA)Additional insulation for building roof systems Permeable paving

• Completed on schedule despite mid-construction retrofitting

3-4-12 XD Report 5

BEQ Package 9 continued

464,000 SF solar project— 4 separate solar array structures

4,680 SunPower E19/318 solar panels, generating 2.1 megawatts/year Offsets 29% of total electrical load

Saves $331,144/yr at current CA power rate

Project designed to be 57% more efficient than baseline code minimum comparable building

Besides cost savings, photovoltaic system provides shade in desert location

2 parking areas, amphitheater, recreation area

Maximizing Sustainability

Approach to Photovoltaic Utilization: Designing for Maximum Solar Panel Efficiency1. Location/placement2. Aesthetic incorporation

Energy and Water Saving Methods Integrated Design with the Local Climate in Mind

1. Thermostats tied to CAC cards at unit entry doors2. Fan coil override switch on operable windows 3. Occupancy sensors in public areas4. Water saving plumbing fixtures, Mojave adapted landscape with subsurface irrigation, graywater filtration system.

3-4-12 XD Report 8

Mechanical Systems

• Mechanical systems, both projects Designed with advanced metering capabilities tied to Base Energy Management

Controls System (EMCS) through dedicated computerized Supervisory Control and Data Acquisition (SCADA) program

BEQ complexes have preconditioned (heating and chilled water) outside air systems to temper airflows via a central air distribution system per floor

Use of pressure-independent control valves to enhance efficiency of 4-pipe hydronic system and allow for whole-building design approach through seamless controls integration

3-4-12 XD Report 9

Selecting Green Elements

Criteria for Selection1. Cost Efficiency

2. Impact on Design3. Contribution to Net Zero Ready4. Examples of Green elements:

. Window interlock systems that shut off fan coil units when windows are opened

. Perforated metal exterior sunshades with vertical fins to cut off low angle morning and afternoon solar heat gain

. Native, drought-tolerant landscaping irrigated with subsurface drip irrigation to minimize evaporation

. 100% of the landscape irrigation provided through graywater filtration system supplying non-potable water recovered from the buildings’ laundry facilities.

Housing Worthy of a War-Fighter

Overall goal: Address 2009 Marine Corps BEQ Enhancement Initiative to create “more home-like living environment for single Marines”

Team Betterments included:. 10% increase in room size. Upgrades on materials, finishes. Additional amenities including amphitheater, exercise circuit course, ‘home theater’ room

10-3-12 Net Zero through Emerging Technologies 11

Housing Worthy of a War-Fighter

1. Campus Site Design and Landscape Architecture

2. Sustainable Site Amenities

3. Home-like living Environments

4. Common areas to promote unit cohesion

Housing Worthy of a War-Fighter

• Both BEQ Packages:– Campus environment– Three 4-story BEQs– 576 two-person rooms– Hotel-style 2-story entrances– Non-institutional styling—e.g., corridors with inset doors, smooth plaster

wall finish applied above honed, sealed CMU chair rails– Parking Garages. Package 9: 706 spaces. Package 4: 540 spaces– Landmark features. Package 9: landmark tower with outdoor

amphitheater. Package 4: 500-seat open-air amphitheater, 420’ Ninja Warrior style obstacle course

– Separated passive/active outdoor amenities

3-4-12 XD Report 13

• Two design approaches

Package 9:

. Multi-purpose space within BEQ buildings

Package 4: . Each BEQ has free-standing 9,825 ‘E-Club’ building

. Complex incudes 445-seat dining facility
