The upcoming Scottish Passivhaus equivalency standard will bring significant changes to housebuilders and the architectural glazing market. This new regulation, expected to take effect by 2025, will require new-build homes to meet rigorous energy efficiency and thermal performance standards equivalent to Passivhaus. This is part of Scotland’s commitment to reducing carbon emissions and improving housing quality.

For housebuilders, this shift means that they will need to adopt more energy-efficient design principles and materials. The construction process will involve enhanced insulation, airtight building envelopes, and improved ventilation systems to meet the stringent performance requirements. Builders will also need to undergo extensive training to ensure they understand and can apply Passivhaus principles, which focus on minimising energy use while ensuring comfort and high indoor air quality.

In terms of architectural glazing, this new standard will place a higher demand on advanced glazing solutions. Triple glazing, for example, will likely become a standard feature, as it helps to minimise heat loss and improve the overall thermal performance of buildings. Glazing systems will need to integrate with other energy-efficient technologies, such as solar control glass, which can reduce overheating while allowing for natural light.

Glass manufacturers and suppliers will need to innovate and offer solutions that meet the higher thermal and acoustic insulation demands of these homes. Products with lower U-values, which measure thermal conductivity, will become a key feature in both windows and doors to help builders achieve compliance with the new standard​(Scottish Construction Now)​(Passivhaus Trust).

Overall, this transition will push both housebuilders and glazing companies to prioritise sustainability, but it also presents an opportunity for those prepared to adapt to the evolving market.
