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

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

Selecting Green Elements
Criteria for Selection
1. Cost Efficiency
2. Impact on Design
3. Contribution to Net Zero Ready
4. 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.
