Ensuring Code Compliance for Insulated Structural Headers Structural headers in load-bearing exterior walls serve a vital role in supporting the structure above window and door openings. However, they can also be significant sources of heat loss if not properly insulated and sealed. Without insulation, structural headers act as thermal bridges, allowing heat to escape and…
Ensuring Code-Compliant Insulated Wall Intersections Proper insulation of interior/exterior wall intersections is a critical component of energy-efficient building design. Ensuring these intersections are insulated to the same R-value as the rest of the exterior wall helps prevent thermal bridging, which can compromise the building’s thermal envelope. Builders, remodelers, and code officials must ensure that wall…
Ensuring Code Compliance for Photovoltaic Systems With the increasing adoption of renewable energy in residential construction, photovoltaic (PV) systems are becoming a common feature on homes. These systems can help homeowners reduce energy costs, enhance property value, and support sustainability goals. However, proper installation and adherence to relevant codes are crucial to ensure safety, efficiency,…
Ensuring Code Compliance for Heat Recovery Ventilators (HRVs) Heat recovery ventilators (HRVs) offer an energy-efficient solution for mechanical ventilation by minimizing heat loss during air exchange. In colder climates, HRVs are particularly effective, as they transfer heat from the outgoing exhaust air to the incoming fresh air, reducing the energy burden on heating systems. Ensuring…
Ensuring Code Compliance for Heat Pump Water Heater (HPWH) Installations Heat pump water heaters (HPWHs) are a highly efficient alternative to traditional electric-resistance water heaters. By utilizing a vapor-compression refrigerant cycle, HPWHs transfer heat from surrounding air to water, significantly reducing energy consumption. However, HPWHs require specific considerations for location, ventilation, condensate drainage, and electrical…
