ASHRAE publishes energy guideline for historic buildings

Tuesday, April 23, 2019

With nearly two-thirds of existing buildings estimated to still be in service by 2050, project teams retrofitting any historic building for energy efficiency can benefit from the content of the new ASHRAE Guideline 34-2019, Energy Guideline for Historic Buildings. 

Guideline 34 provides a step-by-step procedure for sensitive energy upgrading, beginning with forming the project team and gathering building and energy use histories, to instituting energy efficiency measures (EEM).

In addition, building envelope improvements, environmental control strategies, energy system analysis, HVAC selection and lighting design considerations are all addressed in the guideline. All recommendations are made in consideration of preserving the integrity of the historically valuable building character, materials and associated artefacts.

“The committee members writing this guideline are exceptionally knowledgeable about the special issues related to historic buildings and the care needed to preserve them,” said 2018-2019 ASHRAE President Sheila J. Hayter, who also served as chair of the international guideline committee.

“The committee’s intent was to provide guidance for worldwide communities and specifically for entire project teams – not just engineers.”

According to the press release, the guideline is particularly aimed at providing guidance for ‘listed’ historic buildings; i.e., those formally designated or eligible to be designated as historically significant by a governing body.

The cost of ASHRAE Guideline 34-2019, Energy Guideline for Historic Buildings is $53 for ASHRAE members ($62, non-members).
