An efficient future for historic buildings proposed under ASHRAE guideline

Share this Post:

Under a proposed guideline from the American Society of Heating, Refrigerating, and Air-Conditioning Engineers (ASHRAE), historic buildings could be brought from the past into a reduced energy consumption future.


ASHRAE Guideline 34P, Energy Guideline for Historical Buildings, provides advice for energy efficiency and energy conservation improvements involving historic structures. These improvements would seek to minimise disturbances to the historic character, characteristics and materials (significance, value and qualities).


This Guideline 34P will help those engaged in preservation to design and provide energy conservation measures. It will also help those engaged in energy conservation to propose and adopt measures consistent with preservation practice. The guideline addresses planning and operation, mechanical systems, building envelopes and lighting.


The proposed standard is open for a second public comment until 2 May 2016. For further information, please visit the relevant ASHRAE webpage.
