1 Tenant Energy Performance in Commercial Office Buildings NRDC Center for Market Innovation

2 U.S. COMMERCIAL OFFICE REAL ESTATE IMPACT 12 billion square feet = $20 billion in annual energy costs 2

3 TENANT OPPORTUNITY Over 50% of a building’s energy use comes from tenant spaces in commercial office buildings  Optimize energy performance, quality of spaces and building services through owner/ tenant collaboration  Base building energy efficiency goals and performance recognition ratings are enhanced through better tenant energy performance 3

4 TENANT OPPORTUNITY  Workplace quality, occupant comfort and satisfaction improvements are often cited as motivations for high performance tenant space.  Soft benefits have the potential for greater economic impact than energy cost savings.  A process of evaluating and quantifying soft benefits is necessary driver to increase the demand for high performance tenant space. 4

5 VALUE PROPOSITION 5 TENANTS: ↓ energy consumption ↓ operating & maintenance costs ↑ workplace comfort ↑ employee attraction/retention ↑ occupant satisfaction ↑ corporate responsibility & investor recognition REAL ESTATE OWNERS: ↓ energy consumption ↓ operations & maintenance cost ↓ capital plan & infrastructure upgrade cost ↑ occupancy & tenant quality ↑ tenant satisfaction ↑ renewal probability ↑ asset class, value & recognition

6 TENANT ENGAGEMENT Challenges: 1)Data proving payback of energy investments 2)Project process/ execution expertise 3)First cost funding solutions 6 Optimizing energy performance at time of build-out, renovation or capital work maximizes ROI and minimizes incremental cost and disruption

7 ENERGY SAVINGS OPPORTUNITIES 7

8 QUANTIFIABLE RESULTS 8 Baseline energy use can be reduced by 30-50%, optimizing energy performance with a payback of 3-5 years, while providing a more comfortable and better performing building

9 QUANTIFIABLE RESULTS 9 Baseline energy use can be reduced by 30-50% compared to: 1)Existing office space 2)Code standard new tenant space 3)Code standard new tenant space + Pre-retrofit base building

10 QUANTIFIABLE RESULTS 10 Baseline energy use can be reduced by 30-50% compared to: 1)Existing office space 2)Code compliant standards 3)Code compliant standards + Pre-retrofit base building

11 TENANT SPACE ENERGY SAVINGS OPPORTUNITIES 11 Optimize energy performance by addressing all end uses: 1)Reducing loads 2)Installing efficient equipment 3)Managing behavior

12 LEASE CYCLE ENERGY OPTIMIZATION PROCESS

13 TENANT SPACE ENERGY SAVINGS OPPORTUNITIES 13 Tenant Energy Performance Measures (EPMs) (Optimize results by packaging a group of measures) Building Owner Support to Tenant EPMs (Showcase EPMs in a model office suite) Strategies Provided by Building Owner Sub-metered by space/ floor/ net leaseProvide specifications to tenant engineer Building envelope (windows, window film, radiative barrier)Provide tear sheet with details on capital work EPMs Strategies with No or Low Additional Incremental First Cost Select building with natural daylight accessLocate equipment away from windows Design open office layoutLocate equipment in core, design pre built Paint walls white or light colors to reflect lightPaint walls white if space is ‘white boxed’ Seal perimeter walls/ openingsPre seal if perimeter if space is ‘white boxed’ Occupancy sensor/ vacancy sensor lighting controlsInstall in pre-build model space Short Payback Measures High Efficiency LightingProvide specifications and vendors list for competitive bids Optimize HVAC UnitsProvide specifications and vendors list for competitive bids Plug Load ManagementProvide list of technologies and strategies, meet after move-in IT/ Server Room Load ManagementProvide best practices and temperature set points Medium Payback Measures Daylight Harvesting Lighting ControlsProvide specifications and vendors list for competitive bids Demand Control Ventilation (CO2 Sensors)Coordinate building control systems Ongoing Management End use sub-metering- Lighting, plug load, HVAC, IT loads Ensure building infrastructure supports tie in of multiple electrical panels Energy Modeling- Use energy predictive analysis during design, incentive filing, and measurement and verification Provide whole building energy model to Tenant’s engineer
