Green Building - Water and Energy Efficiency
Water provides basic services: human health, cleaning, and waste management. Even in the rainy Northwest, water can be in short supply. Demand peaks during the summer, when rainfall is at its lowest. By focusing on the services water provides, opportunities to minimize water waste indoors, (see the Watersheds & Habitat section on the Location and Landscape page for information on outdoor water use), will reduce water and sewage utility bills, and protect the health of streams that salmon and other wildlife depend upon.
Questions to Consider
- What water-efficient measures are possible for equipment, HVAC, and other industrial processes?
- What water-efficient fixtures are available for kitchen, bath and laundry?
- What opportunities are available for capturing rainwater for non-potable uses?
Like water, energy provides basic services: light, comfort, safe food, and cleanliness, for example. The production of energy touches a vast array of environmental and public health concerns: air quality, climate change, and fish and wildlife habitat, for example. By focusing on the services that energy provides, opportunities to improve energy efficiency, tap clean energy sources, and improve the overall quality of the indoor environment will become apparent.
Questions to Consider
- How can the building be sited and designed to make optimum use of natural daylight?
- How can the building be kept comfortable - warm in winter, cool in summer - "automatically" through passive solar design techniques?
- How can long-term energy costs be minimized by making efficient, integrated choices for the building shell, windows, heating/cooling equipment, appliances and electric lighting?
- For commercial/institutional buildings, what are the cost reduction and operational benefits that "commissioning" will provide?
- What technologies are available for generating clean power on site?
- How can the utility grid be used to "store" surplus power generated on site?

In many states, consumers can reduce electricity bills through net metering. Under net metering, electricity produced by their renewable energy system can flow into the utility grid, spinning the existing electricity meter backwards. Even in the absence of net metering, consumers can use the electricity they produce to offset their electricity demand on an instantaneous basis. If the consumer happens to produce any excess electricity (beyond what is needed to meet the customer's own needs at the moment), the utility purchases that excess electricity at the wholesale or 'avoided cost' price, which is much lower than the retail price.
