The BIG green issues and your role
Tuesday, August 19th, 2008
1. Avoid ozone depleting chemicals in mechanical equipment and insulation.
- CFCs have largely been phased out, but their primary replacements—HCFCs– also damage the ozone layer and should be avoided where possible.
- Reclaim CFCs when servicing or disposing of equipment and, if possible, take CFC based foam insulation to a recycler who can capture CFCs.
2. Use durable products and materials.
- Because manufacturing is very energy-intensive, a product that lasts longer or requires less maintenance usually saves energy.
- Durable products also contribute less to our solid waste problems.
3. Choose low-maintenance building materials.
- Where possible, select building materials that will require little maintenance (painting, re-treatment, waterproofing, etc.), or whose maintenance will have minimal environmental impact.
4. Choose building materials with low embodied energy.
- One estimate of the relative energy intensity of various materials (by weight) is as follows: Lumber = 1, Brick = 2, Cement = 2, Glass = 3, Fiberglass = 7, Steel = 8, Plastic = 30, Aluminum = 80 –source: Building and Environment vol. 17 no. 1
5. Buy locally produced building materials.
- Transportation is costly in both energy use and pollution generation. Look for locally produced materials to replace products imported to your area. (more…)
