Report describing procedures for increasing sensible efficiencies through increased flow rates across the air handling unit and increased indoor coil sizes.
Document presenting a cost effective method that was used by four builders in the Gainesville, FL area to construct interior ducts in over a dozen site built homes.
Report including an overview of the buried duct research and information the retrofit methodology used to install and test the three existing duct systems, including short- and long-term data collection.
Report about City of Meriden Housing Authority's (MHA) collaboration with Jonathon Rose Companies to complete a gut renovation of 126 residential units in the Chamberlain Heights retrofit project.
Document covering the technical aspects of buried and insulated ducts (BEDs), as well as the advantages, disadvantages, and risks of BEDs compared to alternative strategies.
Document presenting results from testing prototype HVAC duct system designs that would locate the entire length of duct work within the air and thermal barriers of the building envelope. These include one that incorporated a high-side supply register, one that utilized a single soffit located within...
Document reviewing current and potential ventilation technologies for residential buildings with particular emphasis on North American climates and construction.
Document covering the pros and cons of compact air distribution systems and the decision criteria that must be considered early in the whole-house design process.
Document about development of recommendations to help residential HVAC designers select optimal supply inlet size and system operating conditions to maintain good thermal comfort in low heating and cooling load homes.
Guide that illustrates how and when to encapsulate ductwork in unconditioned attics, increasing the R-value of duct insulation, mitigating condensation issues, and reducing air leakage.
Report about the impact on the loads when common safety factors are applied to the load calculation process using two houses that meet the 2009 IECC prescriptive path modeled as the accurate baseline.
Research study using modeling to determine optimal combination(s) of components/pumps, high efficiency heat sources, plumbing configurations and controls that result in the highest overall efficiency for a hydronic system.
