Making changes to a home electrical system can make a huge difference in energy usage and monthly cost. Using solar power systems, Energy Star qualified appliances, or something as simple as CFL light bulbs all contribute to a greener environment.
- Provide homeowner with information on “Green Choice” power options.
- Each ton of cooling from air-conditioning units should cover a minimum of 550–600 square foot of space. For more specific sizing, use Manual J or Manual ANSI/ACCA Manual D.
- Install CFL light bulbs. CFLs need a little more energy when they are first turned on, but once the electricity starts moving, use about 75 percent less energy than incandescent bulbs.
Benefits of Green Electrical
In many climates, air conditioning is the biggest item in the power bill. An oversized air-conditioning unit may cycle on and off every 15 minutes—this does not allow the unit to get to optimum efficiency (similar to driving around in first or second gear!), and can thus increase your electrical costs. Efficient air-conditioning units are designed to run from 30 minutes to several hours.
Challenges of Green Electrical
- Getting your HVAC contractor to believe in what was discussed above and specify the proper unit.
- Enlisting the help.
