The Seven Principles of Sustainable Buildings:

1. Reduce resource consumption.

2. Reuse resources.

3. Use recyclable resources.

4. Protect nature.

5. Eliminate toxics.

6. Apply life-cycle costing.

7. Focus on quality.


Heitzman Architects will design every project using the following principles:

1. Design for passive solar energy, oriented properly toward the sun and appropriately shaded.

2. Incorporate passive cooling.

3. Double the minimum amount of insulation required. Use only non-toxic or recycled content.

4. Use Low/No-VOC and Formaldehyde-Free Paint. Use Solvent-Free Adhesives.

5. Use Low VOC, Water-Based Wood Finishes.

6. Use certified wood or finger-jointed wood for all finish trim.

7. Expose the structure to avoid the need for additional finishes.

8. Avoid wall to wall carpet, or use carpet tiles with a company with a take back program.

9. Use recycled content drywall. Try other natural wall finishes instead of drywall.

10. Use composite lumber for all exterior decks.

11. Replace up to 35% of the Portland Cement in the concrete with Fly Ash.

12. Avoid vinyl products. Alternatives for flooring include rubber, cork and linoleum.

13. Specify white or vegetated roofs.

14. Avoid particle board cabinets, Instead, use formaldehyde-free medium density fiberboard, plywood or wheat board for cabinet boxes.

15. Consider bamboo, reclaimed or sustainably harvested wood, and wheatboard for cabinet doors and drawers, and sealed with a no- or low-volatile organic compound clear finish.

16. Specify on-demand hot water system rather than a whole house re-circulating hot water loop.

17. Specify dual flush toilets.

18. Recycle Job Site Construction and Demolition Waste. Salvage all removed doors and windows for possible reuse.

19. Use treated wood that does not contain Chromium, CCA or Arsenic for exterior exposed framing and sill plates.

20. Specify drip irrigation system for landscaping to save water, and indigenous xeriscaping plants that require little water.

21. Incorporate permeable paving at all driveways and exterior surfaces.

22. Reuse concrete form boards, or reusable slip forms.

23. Insulate foundations before backfill.

24. Specify engineered lumber instead of solid sawn lumber.

25. Use OSB for subfloor and sheathing.

26. Install a whole house water filter.

27. Provide dimmers and occupancy sensors on all light switches.

28. South and west facing walls to have a high thermal mass material (concrete or masonry).

29. All appliances to be high level EnergyStar models.


Goals to achieve High Performance Buildings:

1. Establish a collaborative team approach during the design phase, assuring cooperation among building owner, facility manager, users, designers and contractors.

2. Engage the local community at all stages of the process.

3. Educate building users on the philosophy, strategies and controls included in the design, construction, and maintenence of the building.

4. AEstablish a vision that places a high value on preservation of existing buildings and materials.

5. Design buildings that are energy-efficient.

6. Consider embodied energy of all products used in the construction and completed building.

7. Consider the true cost of a building's impact on the local and regional environment.

8. Consider life-cycle costs of all products specified. That is the cost of manufacture, operation, maintenence and disposal.

9. Create opportunities for interaction with the natural environment.

10. Maximize use of local building materials.

11. Minimize demolition.

12. Minimize construction waste.

13. Create buildings that can easily be reconfigured and reused.

14. Create buildings with healthy indoor environments.

15. Use low-tech products and systems.
