Editor's Notes
- Seek out grid information for your area. Major trends and major considerations to build into your building.
- Start with practical boundaries โ existing building renovation? Major massing or construction system being considered?
- Pick measures for key design parties, who is responsible for each one? And pick measure to compliment one another. Will thermal mass really give me benefits without thinking about pre-heating and pre-cooling and can my building even do this comfortably?
