Review of a Free Online HVAC System — Not Unit — Energy Consumption Tool
Instructors: Greg Cunniff, Taco; Rick Bostian, Chairman, HIA-C; Mark Chaffee, Chairman, RPA; Mark Handzel, Xylem/Bell & Gossett; and Mark Hudoba, Uponor
Under IAPMO’s administration, the HIA-C committee, consisting of multiple HVAC equipment manufacturers including four pump companies, is delivering a Building Efficiency System Tool™ (BEST) using Building Energy Efficiency Rating (BEER) curves. Using  BEST, the group has moved from unit AHRI test ratios alone to complete system ratings. BEST includes 30 predefined systems with enough agreed-upon defaults so that a design team member can compare operating and life-cycle output utilizing building specific input. The minimum information required is building size and location. Building size is used to determine loads and system configuration, and location yields relevant utility costs against bin weather data and installed system cost. As more information is defined the defaults can be changed. Because the ASHRAE Headquarters building in Atlanta has been extensively monitored, the presentation will include a review of how BEST is better with BEER.
