environmental, social and governance (ESG) performance of real assets, which
includes real estate. They use assessment methodologies, objective scoring, and
standardized benchmarks to provide asset-level operational performance data.
Gross energy intensity
Gross energy intensity is the ratio between total consumption of a particular energy
source (for example: a group of buildings) and the total square footage of those
buildings. This includes buildings and floor space where the energy source is not
actually being used.
H
Heat pump (geothermal)
A geothermal heat pump is a ground source used for heating and cooling systems for
buildings. It takes advantage of the consistency of temperatures in the earth's
ground throughout the different seasons.
Heating, ventilation, and air conditioning (HVAC)
HVAC is a technology used to control the temperature, humidity, and purity of the air
in indoor environments, particularly buildings or vehicles. HVAC provides comfort and
healthy air quality to the occupants of the environment.
Heating intensity
Heating intensity is a ratio of heating consumption to square footage of heated floor
space and heating degree days. This ratio provides a way to compare different types
of buildings or households by taking into consideration building size and weather. It
is calculated on a weighted, aggregate basis according to the following formula
Heating Intensity =Btu for Space Heating / (Heated Square Feet * Heating Degree-
Days).
