The Hydronics Industry Alliance – Commercial (HIA-C) Building Efficiency System Tool™ (BEST) provides annual energy consumption and lifecycle cost comparisons, based on actual system performance data, for your building’s HVAC system in just minutes! The BEST uses AHRI-certified performance data and building energy efficiency ratings to model the HVAC system as it will operate in real life – not the test lab.
What you input: Location of building, size of building, and number of floors. Then select up to four HVAC systems to compare side-by-side.
What the BEST outputs: Installation cost, replacement cost, maintenance cost, monthly energy cost, electrical and fossil fuel consumption costs, total system life cycle cost, cumulative life cycle cost by year, system payback time, pump and fan HP, system coefficient of performance (COP), and more.
Published test data doesn’t always equal actual performance. The BEST delivers accurate, fast, and free efficiency estimates for early HVAC system comparison. Read "Industry Cooperation Produces BEST results" in Radiant Living.
