With energy costs continuously rising, many homeowners are looking for ways to reduce their energy usage and monthly bills. A home energy makeover allows you to pinpoint problem areas in your house wasting energy and address them through upgrades and efficiency improvements.
Targeting just a few key areas can lead to significant energy savings, money savings, and increased home comfort. If you don’t know where to start, here are the top areas to focus your home energy makeover on for maximum impact:
- Insulate The Attic
One of the most important areas to insulate your home is the attic. Heat rises, and in the winter, much of the heat generated to keep your home comfortable can escape through the roof without sufficient insulation. Therefore, properly insulating and sealing your attic can reduce heat loss through the ceiling by up to 30%.
For best results, consider the following attic insulation tips and get expert advice from professional insulation contractors like Raycore:
- Check The Current Insulation Level In Your Attic. The recommended insulation level varies by climate zone, typically ranging from R-30 to R-60. If your attic insulation is less than the recommended level, adding more is one of the best investments you can make.
- Ensure Even Distribution. It’s essential to ensure that the insulation is distributed evenly, with no low spots or gaps. Besides insulating attic floors, adding insulation to sloped attic walls and knee walls can further reduce heat transfer to the exterior.
- Consider The Type Of Insulation. Different insulation materials, such as fiberglass, cellulose, or foam, offer varying levels of effectiveness and may be better suited for specific areas of your attic. Researching or consulting with a professional can help you choose the most appropriate type for your needs.
- Address Ventilation. Proper attic ventilation is crucial to prevent moisture buildup, which can reduce the effectiveness of insulation and lead to mold growth. Ensure that your attic has adequate ventilation for air circulation, even after installing new insulation.
These steps will help maximize the efficiency of your attic insulation, further reducing energy loss and enhancing the comfort of your home.
- Upgrade Windows
Windows can be one of the weakest links regarding heat and cooling loss in a home. If your windows are more than 20 years old or are equipped with single-pane glass, upgrading to new, energy-efficient models is a smart move. New windows feature improved glazing that better insulates, as well as advanced frame materials and weatherstripping to reduce air leaks.
The National Fenestration Rating Council (NFRC) label on windows provides key energy performance specifications. Look for whole-window U-values below 0.30 and Solar Heat Gain Coefficients (SHGC) lower than 0.40. Install north-facing windows with low SHGCs to minimize summer heat gain, while south-facing windows with high SHGCs allow for free winter sunlight.
Proper window orientation maximizes these benefits. Also, consider low-E coatings to further enhance efficiency. Replacing all single-pane windows with ENERGY STAR-certified models can reduce heating and cooling costs by up to 12%.
- Seal Air Leaks
Air leaks can be a major source of energy loss in a home, allowing conditioned air to escape outside in winter and hot outdoor air to seep in during summer. These leaks make your heating and cooling systems work harder and lead to increased energy consumption and higher bills.
To effectively seal air leaks and enhance your home’s energy efficiency, consider the following steps:
- Conduct A Professional Energy Audit: Before you begin sealing leaks, it’s highly recommended to conduct a professional energy audit. Energy auditors use specialized tools, such as blower doors and infrared cameras, to identify hard-to-detect air leaks. This comprehensive assessment can help prioritize the areas that need sealing, ensuring your efforts are as effective as possible.
- Identify Common Leak Sources: Check for leakage in windows, doors, electrical outlets, attic hatches, pipes, wires, chimneys, and recessed lights. These are common sources of air leaks in many homes.
- Seal Gaps And Openings: Use caulk for non-moving joints, like those around window frames, and weatherstripping for movable components, such as doors and operable windows. Caulk is ideal for sealing smaller gaps, while weatherstripping can address larger openings and movable parts.
- Install Foam Gaskets: Behind outlet covers and switch plates on exterior walls, installing foam gaskets can prevent air from leaking into and out of your home, further reducing energy loss.
- Additional Measures: Sealing attic hatches with weatherstripping and applying window shrink film can also prevent warm air from escaping during the winter and hot air from entering during the summer.
By addressing air leaks with a strategic approach, starting with a professional energy audit, you can improve your home’s energy efficiency by up to 20%. This helps maintain comfortable temperatures and contributes to lower energy bills and a smaller carbon footprint.
- Upgrade HVAC Equipment
Heating and cooling account for over 40% of a home’s energy usage. An inefficient or improperly sized HVAC system forces the unit to work harder than necessary to maintain comfort. Upgrading from older equipment to newer, high-efficiency systems can reduce HVAC energy usage by 20% or more.
Replace very old central air conditioners with a new, ENERGY STAR-certified model. When it’s time to replace an aging gas furnace or heat pump, opt for a system with an AFUE rating of more than 90% for furnaces or an HSPF rating of more than 9.5 for heat pumps. Have a professional assess your home’s insulation levels and ductwork before sizing a new system. Proper sizing ensures the system’s optimal performance.
In addition to the equipment itself, upgrading ductwork and filters, maintaining the system properly, and scheduling regular tune-ups can also maximize energy efficiency. Installing a programmable thermostat can optimize settings based on whether you are home or away. Smart thermostats further refine this by adjusting temperatures to match occupancy patterns.
- Seal Ductwork
If you have a forced-air heating/cooling system, sealing your ductwork is essential. Leaks in ductwork can account for up to 30% of a home’s energy loss.
Ducts located in unheated attics, crawl spaces, and garages are particularly susceptible to leaks. Use mastic sealant or metal tape to seal joints and connections.
Seal duct register openings to floors, walls, and ceilings with caulk and install foam gaskets behind outlet covers. Test ductwork for leaks and address problem areas to improve airflow and efficiency. Properly sealed ducts can reduce energy bills by up to 20% annually.
- Upgrade Lighting
Replacing old incandescent bulbs with efficient LED bulbs is a straightforward and cost-effective way to lower energy consumption in your home. Opting for Energy Star-certified LED bulbs ensures you’re choosing products that meet high efficiency and longevity standards. However, it’s essential to understand that the actual financial savings from switching to LED lighting can vary based on factors such as how often you use your lights and the cost of electricity in your area.
To maximize your savings with this eco-friendly home improvement, consider the following:
- Prioritize High-Use Areas: First, replace bulbs you use frequently in fixtures. This targets the most significant potential for savings.
- Smart Controls: Incorporating dimmers, timers, and motion sensors can further reduce energy use by ensuring lights are only on when needed.
- Optimize Lighting Design: Use task lighting over ambient lighting when possible, and choose the appropriate wattage or lumens for each area to avoid overlighting.
By considering these factors, homeowners can better estimate their savings and make more informed decisions about upgrading to LED lighting. While the initial investment may be higher than traditional bulbs, the long-term savings, reduced energy consumption, and longer lifespan of LEDs often justify the switch.
- Insulate Hot Water Pipes
Wrapping hot water pipes with insulation minimizes the loss of heat while water is transported from the heater to your taps and appliances. For optimal savings, insulate both hot and cold water pipes, especially those with long runs from the water heater to faucets, as the effectiveness of this measure can vary based on distance.
Use preformed snap-on pipe insulation on straight pipe runs. For elbows and tee fittings, wrap insulation around and secure it. Insulate at least the first 6 feet of pipes leading away from the water heater for best results.
Insulating pipes increases efficiency by allowing less heat to dissipate before reaching endpoints. This enables you to lower the water temperature on your water heater while still getting comfortably hot water when needed.
- Adjust The Water Heater Temperature
Turning down your water heater’s temperature to 120°F not only saves energy but is also considered a safe and efficient setting. This temperature is effective for reducing heating costs while minimizing the risk of scalding. However, it’s important to maintain this minimum temperature to prevent the growth of legionella bacteria, which can pose health risks.
If your home has a dishwasher that requires higher temperatures, verify its specifications to ensure proper sanitation. For additional energy savings, consider insulating your water heater tank to reduce heat loss, always adhering to the manufacturer’s safety instructions.
