Energy Simulation Analysis

Results of our energy simulation analysis are summarized in the table and chart at right. In all, the Highland Center for Natural History will achieve $2,350 (66%) in annual utility savings per year as compared to a minimally compliant ASHRAE 90.1 building. Approximately 50% of the energy savings on the building can be attributed to the 7kW photovoltaic system, which has been designed to provide 100% of the building’s electrical needs.

Initial energy modeling demonstrated that, based on the quantifiable amount of passive heating and cooling contribution of the building itself, just how little supplemental heating and cooling would actually be needed. Graph at right illustrates the expected amounts of radiant heating (red bars) and evaporative cooling (blue bars) needed on throughout the year on a month to month basis.


Mechanical System Energy Requirements

Total building system energy requirements from graph at right are as follows:

13,800 BTU/ sq.ft./ year
The 13,800 BTU/ sq. ft./ year energy requirement is roughly one-fifth (1/5) the typical energy required for a conventional commercial building of similar size.
