There are many terms that are unique to (evaluating energy consumption in commercial real estate?)
The following list of terms has been put together to ensure you recieve the most accurate reports for the buildings in your portfolio.
User Types
- Owner
- The Owner is the firm or individual who owns the building.
- Building Manager
- The Building Manager is responsible for maintaining the information relating to the building.
- Program Administrator
- The New York State Energy Research and Development Authority (NYSERDA) is the Program Administrator
- Consultant
- A consultant advises managers and owners regarding Building Performance data.
Scorecard Terms
- Portfolio Manager Score
- This is the score returned by the EPA from data entered into the Focus CRE Toolkit.
- Scoring Date
- The is the date for which the last score was generated. The building and its data will be measured for the preceeding 12 months from this date.
- Passed CRE Data Checks
- This indicates that the data is within acceptable time and quantity boundaries.
EPA score is between 15 and 85
SQFT is within 100-1000 per person.
- Data Verified By Engineer
- This indicates that an engineer has reviewed the data and determined that the data is valid, and the building should be included in the building comparison data set.
(Not currently implemented)
- LEED EB (min score)
- This is the lowest score you can receive and still be eligible for the LEED EB Rating on your Building.
Leadership in Energy and Environmental Design for Existing Buildings Rating is a benchmark promoted by LEED.
- Energy Star (min score)
- This is the lowest score you can receive and still be eligible for the Energy Star Rating on your Building.
- Source Energy
- This is the calculated energy used at the energy-supplier source (typically a power plant).
- Site Energy
- This is the energy consumption directly at the building.
- Weather Normalized
- Weather Normalization is a calculation designed to remove the effect of year to year weather variations from consumption data, so Building Performance can be compared across time.
- peer comparison
- Your building is compared against a set of peers in the same New York Metro region.
Building Terms
- Gross Floor Area
- Total number of square feet measured between the principal exterior surfaces of the enclosing fixed walls, including vent shafts and stairwells. Use CAD figures if available.
- Above Grade
- The number of floors above ground.
- Below Grade
- The number of floors below ground.
- Conditioned Area
- The area in sq ft throughout the building served by the heating and cooling systems.
Meter Terms
- Utility Delivery Company
- The company that delivers energy to your building.
- Meter Type
- Master - consumption totals are fed by sub meters.
Sub - consumption totals feed into a master meter (master totals should be used instead for scoring.)
Direct - totals directly reflect consumption.
- Active
- If active, the meter data will be sent to the EPA when the building is scored.
- Spaces Served
- The spaces that this meter serves.
Regression Chart Terms
- Regression
- The regression analysis takes raw consumption and weather data, and calculates formulas that describe Building Performance in terms of Base Load, Heating Load, and Cooling load.
Regression analysis is a standard technique for sifting data to remove noise and to normalize it for comparison.
- Heating / Base / Cooling Load
- These loads are the described by the formulas returned by the regression.
- Regression R2
- R2 is a measure of correlation between the temperature and energy usage. A value closer to 1.0 means that our estimated heating and cooling loads match the raw data more closely.
Space Terms
- Space Type
- The space type per the EPA Portfolio Manager spacetypes.
- Gross Floor Area
- The gross floor area is the total area of the denoted space, measuring from the outside of the exterior walls.
- Operating Hours
- The number of hours per week that this space is occupied.
- Effective Date
- The first date that these figures apply to the space.
