Which metric does ENERGY STAR Portfolio Manager use to normalize energy consumption for weather in commercial buildings?
Answer: Heating Degree Days (HDD) and Cooling Degree Days (CDD)
Portfolio Manager uses HDD and CDD to weather-normalize energy consumption, enabling fair comparisons across different climates.
An office building scores 74 on the ENERGY STAR 1–100 scale. What does this indicate?
Answer: It performs better than 74% of similar buildings nationally
A score of 74 means the building outperforms 74% of similar U.S. buildings in energy efficiency.
What is the primary purpose of 'source energy' normalization in Portfolio Manager benchmarking?
Answer: To account for transmission and generation losses and compare fuels on equal footing
Source energy includes all upstream losses so different fuel types (electricity vs. natural gas) can be compared equitably.
Which building type requires 'weekly operating hours' as a use detail input in ENERGY STAR Portfolio Manager?
Answer: Office buildings
Office buildings require weekly operating hours as a key use detail because occupancy schedules directly affect their energy benchmark score.
A certified ENERGY STAR building must re-certify annually. What must be verified each year?
Answer: A licensed Professional Engineer or Registered Architect must verify the data
Annual recertification requires a PE or RA stamp verifying that the energy and property data entered in Portfolio Manager are accurate.
In Portfolio Manager, what does the term 'gross floor area' exclude when calculating energy use intensity (EUI)?
Answer: Parking garages that are not conditioned
Unconditioned parking structures are excluded from gross floor area in EUI calculations because they are not climate-controlled spaces.
Which federal executive order mandated that federal agencies benchmark their buildings in ENERGY STAR Portfolio Manager?
Answer: Executive Order 13693 (Planning for Federal Sustainability in the Next Decade)
EO 13693, signed in 2015, required federal agencies to use Portfolio Manager to benchmark and track energy performance in their building portfolios.
