Some rules of thumb to reduce energy use are:

  • Program similar spaces together to reduce distribution losses 
  • Use a window-to-wall ratio below 40%, on average
  • Use a window-to-wall ratio below 20% on east and west sides, to reduce low-angle solar gain, and glare; 
  • Reduce direct solar gain with solar shades or building geometry and orientation
  • Distribute heating and cooling loads uniformly throughout all facades for a smaller system size. 
  • Design a tight and well-insulated building envelope to reduce the heating load and improve HVAC performance
  • Use right-sized and efficient heating and cooling systems
  • Consider onsite renewable energy generation.
