In today’s energy-conscious world, ensuring your home is as energy-efficient as possible is crucial. Not only does it help reduce your carbon footprint and keep you more comfortable, but it also lowers your energy bills. While professional energy audits provide a comprehensive assessment of your home’s energy efficiency, identifying everything from air leaks to insulation gaps using specialized equipment, you can still start with a do-it-yourself home energy assessment to pinpoint and address common energy inefficiencies on your own. Here’s a step-by-step guide to conducting your own DIY home energy assessment.
What is a DIY Home Energy Assessment?
A DIY home energy assessment evaluates your home’s energy use and identifies areas where you can improve efficiency. It involves examining various components of your home, including insulation, heating and cooling systems, lighting, and appliances. Performing a DIY assessment can help you make more informed decisions about energy-saving upgrades.
Step 1: Gather Your Tools for a DIY Home Energy Assessment
Before you begin, you should gather the following tools and materials for your assessment:
- Notebook and pen for recording observations
- Flashlight for inspecting dark areas
- Thermometer to check temperatures
- Smoke pen or incense stick to detect drafts
- Infrared thermometer (optional but useful)
- Utility bills for reference
- Phone or camera for taking photos and recording videos for reference later. Contractors, like us at Greenlink, find homeowners’ photos and videos very helpful during initial conversations about energy efficiency services.
Step 2: Inspect for Air Leaks
Air leaks can significantly impact your home’s comfort and efficiency. To identify leaks:
- Windows and Doors: Check for drafts around the edges of windows and doors. Use a smoke pencil or incense stick to see if smoke wavers, indicating a leak.
- Baseboards and Electrical Outlets: Inspect gaps along baseboards and around electrical outlets. These areas often have hidden leaks.
- Attic and Basement: Look for gaps where walls meet the ceiling or floor. Check for signs of daylight or feel for drafts.
Sealing Air Leaks: Use caulk or weatherstripping to seal leaks. For larger gaps, consider using a Froth-Pak Sealant Spray Foam Kit, like this one available at Menards. This type of spray foam sealant is not the same as a professional, commercial spray foam insulation, but it’s fantastic for sealing larger areas.
Step 3: Examine Insulation
Proper insulation is vital for maintaining a comfortable indoor temperature and reducing energy consumption. Here’s how to check your insulation:
- Attic Insulation: Ensure your attic is well-insulated. Measure the thickness of insulation; it should be at least 16 inches for optimal performance.
- Wall Insulation: While it’s harder to inspect wall insulation, you can check for cold spots on interior walls using an infrared thermometer. Uneven temperatures may indicate insufficient insulation.
- Basement and Crawl Spaces: Pay special attention to rim joist areas, which are often overlooked but crucial for preventing air leakage and energy loss. Insulating rim joists with rigid foam or spray foam insulation can significantly improve your home’s energy efficiency. Additionally, ensure crawl spaces are properly insulated to maintain a stable temperature and reduce moisture infiltration.
Step 4: Assess Heating and Cooling Systems
Heating and cooling account for a significant portion of your energy usage. Evaluate these systems to ensure they’re operating efficiently:
- Furnace and Air Conditioner: Check the age and condition of your furnace and air conditioner. Units older than 10-15 years may be less efficient.
- Ductwork: Inspect ductwork for leaks or disconnected sections. Sealing ducts with foil tape or mastic can improve efficiency.
- Thermostat: Ensure your thermostat is functioning correctly. Consider upgrading to a programmable or smart thermostat for better control over your heating and cooling.
Step 5: Evaluate Windows and Doors
Windows and doors can be major sources of energy loss. Here’s how to assess them:
- Window Glazing: Check if your windows are double-glazed or have low-E coatings. Single-pane windows are less efficient and may need upgrading.
- Weatherstripping: Ensure weatherstripping around windows and doors is intact. Replace any worn or damaged strips.
- Storm Windows: If you have storm windows, ensure they are properly installed and closed during colder months.
Window and door draft stoppers, like these Dual Drafter Blockers available at Menards, can help decrease drafts and improve the efficiency of heating and cooling your home. Especially during cold, winter months!
Step 6: Inspect Lighting
Lighting is another area where you can save energy:
- Bulbs: Replace incandescent bulbs with energy-efficient LEDs or CFLs. These use less energy and have a longer lifespan.
- Lighting Usage: Assess your lighting habits. Turn off lights when not in use and consider installing dimmer switches or motion sensors.
Step 7: Review Appliances and Electronics
Appliances and electronics contribute to your overall energy consumption. Here’s what to look for:
- Energy Star Appliances: Check if your appliances are Energy Star certified, indicating they meet energy efficiency standards.
- Standby Power: Unplug devices not in use to reduce phantom energy consumption. Use power strips to easily switch off multiple devices.
- Refrigerator: Ensure your refrigerator is set to the optimal temperature (37-40°F) and the freezer at 0-5°F. Clean coils and check seals regularly. You would be surprised as to how filthy and dust-coated those coils and wires in the back of your refrigerator can get, and how much that can affect efficiency and air quality!
Step 8: Check Water Heating
Water heating can be a hidden energy drain. Here’s how to optimize it:
- Water Heater: Newer water heaters won’t feel warm to the touch, but if you have an older one, it may. You can buy water heater insulation wraps to help improve efficiency.
- Hot Water Pipes: Insulate exposed hot and cold water pipes adjacent to the water heater. Copper pipes conduct heat, so even cold pipes can leak heat to the surrounding room, since they’re sitting in a hot water bath inside the water heater.
- Fixtures: Install low-flow showerheads and faucet aerators to reduce water usage.
Step 9: Analyze Utility Bills
Reviewing your utility bills can provide valuable insights into your energy usage patterns and help you identify potential inefficiencies. Here’s how to effectively analyze your bills:
- Usage Trends: Compare your energy usage month-to-month and year-to-year. Look for significant changes or spikes in consumption. For example, a sudden increase during a specific month could indicate an issue with your HVAC system or the need for better insulation during extreme weather conditions.
- Energy Costs: Examine your energy costs closely. Note any significant increases that aren’t related to seasonal changes or rate hikes. Consistent or unexplained rises in costs might signal inefficiencies such as outdated appliances, poor insulation, or air leaks that need to be addressed.
- Peak Usage Times: Identify peak usage times on your utility bills. Understanding when you use the most energy can help you adjust habits to reduce consumption during those periods. This can be particularly useful if your utility company charges higher rates during peak hours.
- Compare Rates and Plans: Check if you are on the most cost-effective rate plan offered by your utility company. Some companies offer time-of-use plans that could save you money if you shift energy-intensive activities to off-peak hours.
Step 10: Make an Action Plan After Your DIY Home Energy Assessment
After completing your audit, create an action plan to address identified issues:
- Prioritize Upgrades: Focus on the areas with the most significant potential for energy savings, such as sealing air leaks and improving insulation.
- Set Goals: Set realistic energy-saving goals and track your progress.
- DIY or Professional Help: Determine which tasks you can handle yourself and which may require professional assistance.
