Assessing the Market and Space-Conditioning Needs of Low-Load Homes

High performance, low-load homes face unique space conditioning challenges that are not adequately addressed by HVAC design practices and equipment offerings. Equipment manufacturers have yet to include a diverse set of low-capacity equipment in their product offerings due to a lack of understanding of (1) where the low-load home market is headed and (2) the load profiles typical to low-load homes. This project looks to address both of these information gaps and ultimately send the necessary low-capacity equipment market signals to manufacturers, enabling them to design better products to meet production builder needs. The team will develop a technical whitepaper and presentation on the performance and cost tradeoffs of various equipment types/systems at meeting the comfort requirements of low-load homes, and forecasting the market penetration and equipment needs for these low-load homes.
