What’s the difference between PAS 2035 and PAS 2038?

PAS 2035 and PAS 2038 are both British standards that relate to energy efficiency and sustainability in the built environment. The two British Standards share some similarities, but they each have their own distinct focus and objectives.

PAS 2035: Specification for the energy retrofitting of domestic buildings

PAS 2035 provides guidance for improving the energy efficiency and performance of existing domestic buildings, establishing a structured approach to assess, plan, and implement retrofit measures.

  • PAS 2035 focuses on the holistic improvement of building performance, considering factors such as thermal efficiency, heating systems, ventilation, and renewable energy sources.
  • It outlines a process for identifying retrofit opportunities, undertaking assessments, developing retrofit plans, and monitoring the outcomes to ensure the desired energy performance improvements are achieved.
  • PAS 2035 includes requirements for competency and accreditation of professionals involved in retrofit projects to ensure high-quality workmanship.

PAS 2038: Specification for managing the retrofitting of buildings for improved energy efficiency

PAS 2038, focusses on reducing greenhouse gas (GHG) emissions associated with building operations by establishing a systematic approach to measure, report, and reduce emissions.

  • PAS 2038 covers a broader range of sectors and activities, including energy use, transportation, manufacturing, construction, and agriculture, compared to the domestic focus of PAS 2035.
  • It provides a framework for organizations to quantify and report their emissions, set reduction targets, and implement measures to achieve those targets.
  • PAS 2038 encourages the consideration of broader environmental impacts, resource efficiency, and sustainable practices beyond energy efficiency alone.

Neither PAS 2035 or PAS 2038 are mandatory, but compliance with certain aspects of each Standard may be required to access specific government schemes, funding programs, or incentives related to energy efficiency and retrofitting. It is therefore recommended to consider both PAS 2035 and PAS 2038 when undertaking a retrofit project, it to ensure a comprehensive and well-managed approach.
