"We just had our attic and crawl space insulated and a moisture barrier put in. The crew showed up on time and every one of them was polite and professional. We could tell they had a lot of experience working together because they were super organized. While the boss, Dave, walked us through the process in detail, making sure we understood the job, behind him the crew set up quickly and efficiently, treating our home with respect. They were finished right on time, too, and left our house looking as if they had never been there. Before they left, Dave showed us their work and explained how these improvements would make our home more energy efficient. Every crew member made sure to say goodbye to us. They were amazing people! We highly recommend Building Energy Experts."

Euro-Tech, Inc. has been the Midwest's premier home improvement company for over 23 years .

"The crew that was sent was professional and thorough. All the old windows (approximately 20) were removed by noon and all the new windows were installed, sealed, and cleaned by the end of the normal work day. A crack developed in one a couple of years later and, while it took a bit of time due to Holidays and the onset of the Pandemic to get the window ordered, Tom and Niko (the service people sent to replace it) were equally as thorough and professional. It took longer to fill out the paper work than it took them to remove and replace the cracked window. We have noticed a significant drop in our heating and cooling costs after the installation of these windows. They are a bit pricey but that is because the quality is superior. If you want good solid windows that look great for your house or business, I highly recommend Eurotech, Inc."

Energy Efficiency Auditing questions, answered by experts

DIY is possible with basic tools. Professional audits provide comprehensive assessments and tailored recommendations.

An average, 400-square-foot electric heated driveways consume approximately $3 per hour in terms of electricity. The price may slightly fluctuate depending on your local energy cost. A simple formula to calculate your heated driveway’s total wattage consumption is by multiplying the square footage by 50 watts and then dividing it by 1,000 to get the kilowatt number. Multiply that with your local energy cost per hour and there you have the hourly operating cost.

A couple of the best ways to find a reputable energy auditor is by determining whether they are HEP-certified by the Building Performance Institute (BPI). This certification will help you narrow down your list of professionals to the most qualified pros with the most relevant experience. 

You can also choose from the Department of Energy’s certified list of energy auditors or Angi’s contractor licensing tool to find pros in your area.

Window AC units use a fair amount of electricity during use, but the usage pales in comparison to central units. As a matter of fact, window units use around a third of the amount of energy as a central AC. On average, a window air conditioner costs between $15 and $40 per month to run, though this depends on a number of external factors.

Motion-sensor lights use one watt while on standby and five watts while turned on. They’re usually on for one hour over a 24-hour period, bringing the total wattage to about 28 watts per day. LED lights use around 6.5 to 8 watts while on. If you leave an LED light on all night, with night ranging from 10 to 14 hours, you’re looking at using 65 to 112 watts a night. You can minimally cut your wattage in half by switching to a motion-sensor light.
