Small Design Choices That Reduce a Home’s Energy Use
You don’t need solar panels or a heat pump to make a home extension more efficient, though both are worth considering separately. A lot of the difference comes from smaller, less visible choices made at design stage.
Orientation, even on a small extension
Where windows and doors face affects how much a room overheats in summer and how much natural heat it gets in winter. On a typical London plot you don’t have much choice in orientation, but you do have choice in how much glass you put where, and that’s worth thinking through rather than defaulting to glass on every wall.
Ventilation, not just insulation
A well-insulated, airtight extension needs proper ventilation, or moisture builds up and air quality suffers. Building regulations require this to be designed in, usually through extractor fans or a ventilation system sized correctly for the room.
These aren’t dramatic changes, but they add up to a house that’s genuinely more comfortable to live in, not just one that looks efficient on paper. Get in touch if you’d like these considered properly in your project.
