Energy efficiency refers to using less energy to achieve the same goals or outcomes. Some key factors that affect energy efficiency include:


• Equipment and appliance selection.

Choosing equipment that is specifically designed to be more energy efficient, such as Energy Star rated products, can significantly impact your energy usage and costs. Things like dehumidifiers, air conditioners, furnaces, refrigerators, etc.

• Insulation and air sealing.

Adding insulation to your attic and walls, and sealing and weatherstripping air leaks and drafts improves the efficiency of your heating and cooling equipment. Reduce air leakage for the highest efficiency.

• Lighting selection.

Using LED light bulbs, CFLs or other efficient light options rather than incandescent bulbs can cut lighting costs substantially. Efficient lighting lasts longer too, so you replace them less often.

• Thermostat setting.

Lowering the thermostat setting on your water heater by 10-15 degrees Fahrenheit can reduce heating costs by 3% for every degree lowered. Lowering the thermostat in winter and raising it in summer helps too.

• Energy efficient windows.

Installing windows that are rated high for efficiency, such as double or triple pane glass with low-E coatings, helps prevent heat transfer and significantly improves the performance of your HVAC system.

• Using a programmable thermostat.

A programmable thermostat can automatically lower the temperature setting when you are away or sleeping to save up to 10% per year on heating and cooling costs.

• Washing only full loads.

Running the dishwasher and washing machine only when full helps maximize efficiency and minimizes energy usage. Newer high-efficiency models also use a lot less water which reduces hot water usage and costs.

• Using a fan instead of AC when possible.

Ceiling fans and portable fans use a lot less energy than running an air conditioner, especially at lower temperature settings. Using them allows you to raise the thermostat setting for more efficient AC operation.

• Improving ventilation.

Making sure attics and crawlspaces have adequate insulation and sealing, and that the building envelope is well-ventilated avoids excessively humid or moist conditions which requires more energy usage to control. Enhanced ventilation and insulation is key.
