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…
Ensuring Code Compliance for Gas-Fired Boiler Installations Gas-fired boilers are commonly used in residential and commercial buildings for efficient space heating and hot water supply. These systems heat water or steam, which is then distributed throughout the building using radiators, baseboards, or radiant floor systems. Ensuring code compliance for gas-fired boilers is crucial for safety,…
Understanding Floor Insulation Requirements and Code Compliance Floors above unconditioned spaces—such as basements, vented crawlspaces, cantilevered floors, and garages—are critical components of a building’s thermal envelope. Proper insulation and air sealing are essential to minimize heat loss, prevent cold spots, and enhance energy efficiency. Previous versions of building codes required floor insulation to be in…
