1. Design co-operation to find and solve design problems that affect other designers outcome

  2. Aim for as simple as possible solutions to increase the reliability of solutions

  3. Consider space requirements for HVAC installations

  4. Minimize thermal bridging or use exterior insulation systems to reduce their effects

  5. Consider the need of all structural components; they may influence on thermal properties and cost efficiency

  6. Use modular dimensions, e.g., 600 mm for frame walls and windows

  7. Design for air barrier

  8. Consider ways and means to seal all components leading through a structure

  9. Design for wind barrier

  10. Consider the order of site work already in design

  11. Consider moisture dry-out from thick structures; avoid double vapour barriers in wet rooms
