2RW conducted an energy audit including whole building energy simulations with eQUEST. A baseline model – created and calibrated using metered and logged data – reflected the current building operation and energy consumption. The model was then altered to incorporate recommended ECMs. The difference in energy consumption and cost between the baseline and subsequent models quantified the anticipated energy savings. The ECMs analyzed were BAS upgrades and testing, adjusting, and balancing (TAB) implementation. The BAS ECM was identified during a pre-commissioning assessment performed by 2RW as part of the energy audit. In all, the ECMs developed by 2RW will save in excess of $3,000,000 per year with an implementation cost of nearly $31,000,000.

2RW was contracted to provide design services for the implementation of electrical and TAB ECMs. Additionally, 2RW performed peer reviews of drawings developed for the BAS optimization to ensure the intent of the energy conservation measures was preserved. 2RW served as the general contractor’s commissioning representative during the development of functional performance tests.
