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.
