PBR 2025 Tips
To achieve PBR 2025 certification, buildings must meet specific requirements for space heating demand, airtightness, thermal bridging, and renewable energy generation. Here are a few tips to help you design and construct PBR 2025 certified buildings:
Tip 1: Start with a well-insulated building envelope.
The building envelope is the primary barrier between the conditioned space and the outside environment. A well-insulated building envelope will help to reduce heat loss in the winter and heat gain in the summer, which will reduce energy consumption and costs.
Tip 2: Pay attention to airtightness.
Airtightness is a measure of how well a building envelope prevents air from leaking in or out. A building with good airtightness will be more energy-efficient and comfortable, and will be less likely to have problems with condensation and mold.
Tip 3: Minimize thermal bridging.
Thermal bridging is the transfer of heat through a material that is more conductive than the surrounding materials. Thermal bridging can occur through framing members, windows, and doors. By minimizing thermal bridging, you can improve the energy efficiency of your building.
Tip 4: Use renewable energy sources.
Renewable energy sources, such as solar and wind power, can help to reduce the environmental impact of your building and can also save you money on energy costs. PBR 2025 certified buildings must generate a certain percentage of their energy from renewable sources.
Tip 5: Consider passive design strategies.
Passive design strategies, such as passive solar heating and natural ventilation, can help to reduce the energy consumption of your building without the use of mechanical systems. PBR 2025 certified buildings often incorporate passive design strategies.
By following these tips, you can design and construct PBR 2025 certified buildings that are energy-efficient, sustainable, and comfortable.
