Green means different things to different people; use the information and links below to learn about the possibilities for your project and decide how you can best meet your green building goals.

Designing for a green lifestyle
Changing attitudes about how our communities look and operate is an important part of sustainability. Start by talking with your family and your designer and choosing the project goals and strategies that are right for you; setting clear goals and making a plan for your sustainable building project will help you evaluate products, costs and opportunities as they arise.

Water Use (Interior)
By reducing your home’s total water use and supplying non-drinking water fixtures with alternative water sources, you can reduce your utility bills and preserve our supply of clean drinking water.

Electrical Generation
In order to make home generation cost effective, electrical use must be substantially reduced through passive strategies and efficient features. Consider making daylighting a part of your overall Passive Solar design before shelling out for Compact Flourescents, and remember that lifestyle is one of the biggest contributors to energy use. Little things like the setting on your water heater thermostat, inactive appliances left plugged in (“phantom loads”), refrigerator thermostat, etc can have a big impact.
The cheapest energy is the energy you never have to buy!

Building Envelope
With some careful pre-planning, building methods and materials selections can reduce costs, increase energy efficiency, and minimize the environmental impacts of a home.

Material Selection
A lot of materials are marketed as “Green” these days; make sure the product you choose fits your own definition and your project goals. Your selection criteria may include durability, ease of maintenance, toxicity, use of natural resources, manufacturing and transport-related pollution, contribution to energy efficiency, and recyclability when the end of its lifespan is reached.
