Near net zero building requirements can be achieved using:

• Optimized building shape and size with a simple form and well-placed openings:
  • A building with several complex junctions and corners and increased enclosure area will allow far more heat transfer through the
    enclosure than a building that has been designed as a simple form.
• Well-insulated assemblies with minimal thermal bridging for an overall thermally efficient building enclosure:
  • Continuous exterior rigid mineral fibre insulation or deep interior-insulated assemblies are a good starting point for near net zero buildings
• A durable, airtight building
• Thermally efficient windows, doors, and
• High-efficiency mechanical and electrical
• Photovoltaic/ solar energy generation system
