IAPMO introduced the latest upgrade to the Building Efficiency System Tool (BEST) software, available for download at www.iapmo.org/hiac.
BEST is a quick, easy and reliable way to compare the energy and life cycle costs of up to four HVAC systems at one time. It allows users to evaluate and compare various HVAC system candidates early in the conceptual design phase, before final design and construction, in order to save time and money and complete projects more efficiently.
