HVAC Sizing Tool
HVAC ST (often referred to as “HVAC Street”) allows HVAC contractors to calculate room-by-room or zone-level heating and cooling loads for existing and new small buildings. It allows quick and easy house description and avoids excessive data entry required by other sizing and design tools on the market. This unique online tool does the job of much more expensive industry software programs in far less time. HVAC ST users can go from accurately sizing load and demand to printing out design specifications in about 30 minutes.
HVAC ST is based on ACCA Manual J and D, with common assumptions used to speed data entry. It was tested at a national level and demonstrated consistent results with other ACCA-approved software and ACCA Manual J and Manual D calculations. The Northwest Energy Efficiency Alliance (NEEA) developed the tool in collaboration with Clearesult Inc. to support energy efficiency programs of northwest utilities. In 2020 it was made available for anyone to use without charge, though the utility incentive program connections are only available in the four Pacific Northwest States.
