HVAC systems included in manufactured homes can be characterized as low-cost systems that deliver expensively conditioned air through ductwork prone to leakage. The challenge is increasing manufactured home energy performance with innovations that are attractive to manufacturers, dealers, and buyers without substantially raising the purchase price.  \nMarket stakeholders and actors provided input on processes, costs, HVAC considerations, and feedback on the proposed HVAC innovations. We developed a detailed characterization of—and weighting factors for—the new manufactured homes market (regional sales, home type, HVAC system type and fuel, and duct system characteristics) . We ran energy models to represent the variety of new manufactured homes across the country and estimated the energy savings for various innovations relative to current industry practice.  \nThe HVAC-related innovations fell into two broad categories: duct-system improvements and increased adoption of heat pumps for space conditioning. We assessed 13 innovations for market applicability, potential energy savings, cost effectiveness, and likelihood of adoption (Error! Reference source not found.) . Ducted heat pumps showed the highest impact with potential energy-cost savings in the range of 35 to almost 60 percent and are likely cost-effective except when competing against natural gas heating in colder climates. Duct-sealing innovations have less savings potential and more uncertainty but may offer the most cost-effective savings opportunities.  \nPandemic, labor, and materials supply chain issues combined with the HFC refrigerant phase out impacted our ability to work with industry partners to consider some innovations for new manufactured homes. They are focused on working through challenges to their day-to-day operations and have limited time to focus on research and development, which influenced our selection of in","cbCaiil1lOjrFMsL","https://ap.wps.com/l/cbCaiil1lOjrFMsL","pdf",3439959,8,86,"English","# Executive Summary\n## Assessment scope and market characterization\n## Innovation categories and evaluation results\n## Recommendations for further testing","[{\"question\":\"What problem does the feasibility assessment address for new manufactured homes?\",\"answer\":\"Low-cost HVAC systems in manufactured homes often rely on ductwork that is prone to leakage, limiting energy performance.
