In response to the declared Climate Emergency, BPT is supportive of sensitive sustainability retrofits, where deemed appropriate, within the historic environment, as well as the sympathetic upgrade of traditional and listed building stock to better meet modern standards. As such, we therefore note a positive opportunity for the sensitive implementation of energy efficiency retrofits and thermal improvements where this does not result in harm or the loss of significant historic fabric.

We are supportive of the principle of installing secondary glazing as a less invasive and easily reversible retrofit measure to improve the thermal performance of a historic building. We note that the principle of secondary glazing has already been secured as part of application 21/00880/LBA (granted listed building consent May 2021). Where sash-style glazing is installed behind the original windows, this would enable the continued function of the windows to open and offer natural, passive ventilation with very limited harm to historic fabric, restricted to the proposed fixing points.

Further information regarding the proposed colour finish of the secondary glazing system is recommended to ensure an appropriate colour match with the existing windows.
