Solar Pool & Water HeatingThis proposal includes measures for saving energy on pool heating: mandatory solar heating requirement for pools and spas, exploration of a variable-speed control installation requirement for pool pump systems, clean-up and clarification of existing requirements, and requirements for pool insulation.
Single-Family Buried DuctsThis measure proposes a prescriptive alternative to high performance attics (HPA) to provide an alternative to adding insulation at the roof deck to reduce thermal losses from ducts in vented attics.
Residential HVAC PerformanceThis code change proposal includes a number of measures designed to improve the performance of Heating Ventilation and Air Conditioning (HVAC) systems in new and existing Single Family and some Multifamily residences. Most of the measures are designed to improve the performance of Heat Pumps (HPs), although in some cases the measures are applicable to other types of HVAC systems as well.
Single-Family High-Performance EnvelopeThis measure targets the thermal performance of the building envelope, including a high-performance building envelope package of evaluating and developing prescriptive code requirements for roofs constructed as cathedral ceiling, evaluating savings potential and cost-effectiveness for cool roofs with higher reflectance and thermal emittance values, high-performance windows as prescriptive in some climate zones, and increasing mandatory wall insulation.
