This project models the energy use and savings of a typical single floor in both a small and a large office building in two different geographical locations in the United States (New York City and Los Angeles). .
Both existing and proposed building (with POUNCE®System improvements) energy performances were modeled using eQuest (v3.64) software, a DOE-2.2 based building energy simulation program.
The parameters of building location and HVAC systems as typified by building size have been selected to measure the effects of the POUNCE®System on the baseline model lighting, plug load, and HVAC system energy performance. Modifications to the schedules for these systems have been performed based on occupancy and/or temperature monitoring enabled by the POUNCE®System components. The improvements modeled are:
- Controlling existing lighting in all areas of the office by occupancy
- Controlling existing equipment and plug loads in all areas of the office by occupancy
- Controlling the outside air intake by occupancy in the small office buildings
- Controlling the outside air intake and temperature at zone level for the large buildings, which are modeled as having finer zone level control
It was found that installing the POUNCE® System in all of the buildings and locations modeled is predicted to provide significant energy and cost savings. The total kWh savings per project ranged from 17.6 to 20.1 % of total per floor electricity use.
Natural gas consumption was predicted to be reduced in three of the four buildings modeled, with a range from 7.4 to 8.9% savings of total per floor gas usage in the two New York buildings and the large Los Angeles one.
