ASHRAE commits to broad building decarbonisation initiatives

ASHRAE has issued a position document on building decarbonisation and its role in mitigating the negative carbon impact of buildings on the environment.

ASHRAE Position Document on Building Decarbonization presents the society’s positions and recommendations for achieving a reduction in emissions through the renovation of existing building stock and improvements to new building designs.

“Building decarbonisation encompasses a building’s entire life cycle, including building design, construction, operation, occupancy and end of life,” said 2022-23 ASHRAE president Farooq Mehboob, Fellow ASHRAE. “ASHRAE is leading the charge in accelerating the mitigation of carbon resulting from energy use in the built environment by providing this roadmap to further our society’s mission of a healthy and sustainable built environment for all.”

ASHRAE’s position is that decarbonisation of buildings and its systems must be based on a holistic analysis including healthy, safe, and comfortable environments, energy efficiency, environmental impacts, sustainability, operational security, and economics.

By 2030, the global built environment must at least halve its 2015 greenhouse gas (GHG) emissions, whereby:

  • all new buildings are net-zero GHG emissions in operation,
  • widespread energy efficiency retrofit of existing assets are well underway, and
  • embodied carbon of new construction is reduced by at least 40 percent.

Additional positions and recommendations include the following:

  • Increasing stringency and enforcement of energy codes are critical for decarbonisation.
  • Whole building life cycle assessment 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 decarbonisation.
  • Decarbonisation policies must contemplate and mitigate impacts on disadvantaged communities and less-developed nations.
  • Building decarbonisation strategies and policies must consider healthy, safe, and comfortable environments; environmental and social impacts; sustainability; resilience; and economics.
  • Promote research and development of heat pump technology.
  • Support the development, update, and adoption of relevant standards and guidelines that facilitate the whole life reduction of GHG emissions from new and existing buildings.
  • Encourage greater collaboration and the development of standards and guidelines among the energy, transportation and building sectors to improve secure building-grid integration, data communication, and optimisation of energy performance (generation, use and storage).
  • Work in partnership with industry to increase the capacity and opportunities for a skilled workforce supporting building decarbonisation.

“ASHRAE’s strength is providing the industry with practical solutions, guidance, and tools to develop science-based approaches to decarbonise the built environment on a global scale,” said ASHRAE task force for building decarbonisation (TFBD) chair Kent Peterson. “ASHRAE’s technical guidance, standards and training have long been the basis for high-performing buildings and GHG emission-reduction strategies and this position document will amplify our efforts towards a more sustainable future for all.”

Registration opened on 15 July for the International Building Decarbonization 2022 Conference, held 5 – 7 October in Athens Greece. Organised by the ASHRAE TFBD and the Hellenic chapter, the conference is intended to provide an exchange of ideas to bridge North American and European collaboration on reducing carbon emissions in buildings.
