Passive Design

Passive Design Strategies

  • Passive heating through harnessing solar gains and capturing the internal heat gains
  • Passive ventilation strategies use naturally occurring air flow patterns around and in a building to introduce outdoor air into the space.
  • Passive cooling strategies prevent the building from overheating by blocking solar gains and removing internal heat gains
  • Daylighting maximizes the use and distribution of natural diffused daylight throughout a building’s interior to reduce the need for artificial electric lighting.

Passive design in buildings is about using natural energy flows to maintain thermal comfort. This can be done by employing various methods such as:

  • Designing with orientation in mind
  • Layout and massing
  • Fabric first approach, and reducing energy demand through better building envelope
  • Shading to reduce solar gains in summer months
  • Designing for natural ventilation
  • Thermal mass
  • Customisable controls

The building envelope acts a barrier between natural climate and virtual climate to meet the required human comfort level. In comfort we refer to; thermal, visual and acoustical comforts.

New build

Each project and site will benefit from different strategies.  Pro Sustainability can assist you from the early stages of your design to achieve the best possible outcomes from your design.


If you wish to refurbish your property, whether to reduce the running costs or reduce your environmental impact and carbon footprint, Pro Sustainability can help. We visit your property and discuss various options, tailored to your objectives and budget.
