Join Us on the Journey to Zero.
Jurisdictions globally are confronting climate change and recognizing that building decarbonization is a significant component of their efforts. The worldwide building sector accounts for about 40% of energy-related carbon emissions and the global building stock is predicted to double by the year 2060.
Buildings remain a key sector that lacks sufficient climate change mitigation policies. As the standards authority for energy usage in buildings, ASHRAE recognizes that our long-standing initiatives in energy efficiency should include greenhouse gas emission reductions based on a holistic analysis including healthy, safe, and comfortable environments; energy efficiency; environmental impacts; sustainability; operational security; and economics.
Eliminating GHG emissions from the built environment is essential to address climate change.
By 2030, the global built environment must halve its 2015 GHG emissions.
1. All new buildings must be net zero GHG emissions in operation, 2. Widespread energy-efficiency retrofits of existing assets must be well underway, 3. Embodied carbon of new construction must be reduced by at least 40%.
By 2050, at the latest, all new and existing assets must be net zero GHG emissions across the whole life cycle.
Decarbonization benefits go beyond reducing GHGs.
Reduced indoor and outdoor air pollution
Improved community health and well-being
Enhanced social responsibility
Increased property valuation
Operational energy-related GHG emissions can be reduced by
Efficiency measures and building electrification
Operations and maintenance
Refrigerants: Low-GWP, minimizing volume, and improving management
Renewable energy sources (on and off site) and energy storage
Building-grid integration and real-time carbon signals
Increasing stringency and enforcement of energy codes are critical for decarbonization.
Whole-building life-cycle assessment (WBLCA) must be considered in future building codes to reduce embodied and operational GHG emissions related to buildings and their HVAC&R systems.
Building performance standards (BPS) should be considered as a policy tool for existing building decarbonization.
Building decarbonization strategies and policies must consider
Mitigating impacts on disadvantaged communities and less-developed nations
Healthy, safe, and comfortable environments
Environmental and social impacts
