Passive Heating: Inside The Box

By understanding the principles that underpin passive heating design, the building you create or retrofit will produce enduring comfort, be far more sustainable and deliver significant financial savings.

The most important design principle when retrofitting or building a new home is to ‘build tight’. This means eliminating air gaps in walls (due to poorly installed insulation), drafts around doors and leaky windows caused by single-paned glass or aluminium window frames. Things like chimneys above open fireplaces, air vents in older houses and even recessed downlights all release heat from your home leaving it less comfortable in cold weather, so identifying these areas are your top priority when looking to reduce the need for auxiliary heating.
