Interested in the concept of Passive House design?
About Passive house
We design our building fabric to minimise heat loss and maximise heat gains, creating a highly efficient, self-sustaining environment. This eliminates the need for conventional heating systems, as passive sources like body heat and sunlight provide sufficient warmth. At Glassworx, we play a crucial role in this process by supplying high-performance, energy-efficient windows and doors that meet Passive House standards. With U-values as low as 0.65, our glazing solutions ensure exceptional insulation, reduced energy consumption, and ultimate comfort.
The design process
A Passive House prioritises a fabric-first approach, ensuring maximum energy efficiency through advanced design and construction. By integrating a super-insulated floor slab, walls, and roof, along with superior air-tightness and thermal bridge-free detailing, it slashes energy consumption by 85% compared to conventional buildings. High-performance, quality-approved windows and doors play a vital role in maintaining insulation, while a mechanical ventilation system with heat recovery (MVHR) captures 95% of internal heat gains, keeping the indoor environment comfortable and efficient year-round.
Dramatic savings
It is observed that a Passive House in the U.K. can cost from 8-15% more than a conventional building. These additional costs come through the upgraded building envelope and mechanical ventilation system. However, over the lifecycle of this increase in capital costs is eclipsed by the dramatic savings made due to reduced energy consumption and the almost non-existent heating bills. Construction costs will of course continue to reduce as the U.K.’s construction sector experience grows.
