Energy efficiency in historic homes
How to gain two energy classes without betraying the original architecture.
Heat pumps, radiant heating and internal insulation deliver significant class improvements even where external insulation is prohibited.
Timber windows with low-emissivity double glazing preserve the historic look and cut heat loss by up to 40%.
Every project starts with an energy diagnosis: we intervene where the return is measurable.
