Everyone wants to have a comfortable, energy-efficient home — an energy-efficient home costs less to own and operate, and can be a plus when it comes to home selling. To achieve the goal of an energy-efficient home, think of your home as a single system. Just like the parts of your body, the parts of the building work together to perform various functions. Every part of both your home and your body is important, but some parts are more crucial than others.

Every home needs adequate insulation, but the amount and types of insulation you choose will vary based your local climate. Consult a qualified professional to ensure that your home has the insulation it needs, or if you’re a landlord, the HOA management service will take care of this.

Heating and cooling represent most of the energy use and waste in a typical home. Many property owners are tempted to use an oversized HVAC unit; however, an appropriately sized unit can be more effective and efficient. Using a programmable thermostat can increase energy savings still further. If you are a landlord, consider using a learning thermostat like the Nest — this type of thermostat will adapt to the desires of your current resident, but still give you ultimate control with a smartphone app that can control the system remotely when needed.

Windows and doors can be energy wasters. If you are thinking of investing in new windows, be sure to get windows that fit the style of your home and meet your needs for energy efficiency. Think about what you’d look for when you are apartment hunting or home buying.

When the systems of your home are running smoothly, you, the owner, will spend less on utilities, but the savings don’t end there. Homes that operate well often cost less to maintain. A home with proper insulation and tightly sealing doors and windows is less susceptible to water damage, for instance.

Making the most energy-efficient choices when you are upgrading your home or building may cost more now, but your savings could last well into the future. Your residents will appreciate the upgrade now, and your future resale value will be improved.
