Atlanta, GA – The American Society of Heating, Refrigerating, and Air-conditioning Engineers (ASHRAE) has released a new edition of its Residential Energy Performance Standard (REPS), setting ambitious targets for reducing greenhouse gas emissions and improving indoor environmental quality (IEQ).

The updated REPS, which is the first major revision since 2019, aims to promote energy-efficient and sustainable building practices in the residential sector. Key changes in the new edition include:

Enhanced GHG Reduction Targets: The REPS now includes more stringent greenhouse gas reduction targets, reflecting the growing urgency of addressing climate change.
Improved IEQ Standards: The standard has been updated to include more rigorous requirements for indoor air quality, thermal comfort, and lighting, ensuring that homes are healthy and comfortable for occupants.
Adaptability to Regional Climate Conditions: The REPS now incorporates more flexibility to accommodate regional climate variations, allowing for tailored solutions to meet specific needs.

The release of the new REPS comes at a critical time, as the building sector is a major contributor to greenhouse gas emissions. By adopting the standard, builders and homeowners can help to reduce their environmental impact while creating more energy-efficient and comfortable living spaces.

ASHRAE has also developed a suite of resources to support the implementation of the REPS, including educational materials, training programs, and technical assistance. These resources will help industry professionals understand the requirements of the standard and apply them effectively in their work.

The new REPS is a significant step forward in promoting energy efficiency and sustainability in the residential building sector. By adopting the standard, builders and homeowners can contribute to a more sustainable future while enjoying the benefits of a healthier and more comfortable home environment.
