Many advantages of HVLS fans are even more pronounced in airplane hangars due to the way they are constructed and the material they are made from.
One of those major projects involves a boiler replacement in the 1921 section of the Hawley School and replacement of the original boiler at the Newtown High School. Mr Bienkowski explained that the district was eligible for several significant rebates from the district’s electricity and natural gas utility, Eversource.
HRVs Lower Radon Levels Because HRVs constantly change out the air in a house, an HRV will reduce radon levels when working properly. During a recent Eden Prairie home inspection that I also performed a radon test at, I had the HRV running during the majority of the radon test, but I tripped the GFCI outlet for the last hour of the radon test during my inspection. Look at the jump in radon levels at the house from NOT having the HRV running! Any time a radon test is performed, if there is an HRV present at the house, it should be up and running throughout the duration of the radon test.
There will always be an inefficiency at some level with equipment, especially when adding carbon filters to scrub air as it leaves the space, so most growers account for a 25% loss in efficiency. To calculate this, multiply the air volume by 1.25.
Oceanside Ice Arena has hosted ASU Hockey since its inception, but what many may not know about the rink is its commitment to sustainability for the last decade.
To understand how an HRV works, interlock your fingers together and picture warm air flowing through fingers in one hand, and cold air flowing through the fingers in the other hand.
Long-term monitoring of labs, holding and procedure rooms provides continuous awareness to any change in the environment due to new equipment, new procedures or personnel work habits, equipment that is only occasionally operated, and construction activity interior or exterior to the building. As an example, maintenance to the ventilation systems and exhaust hoods, or general wear over time can cause an increase in ultrasonic sound that would not be detected otherwise.
Brian Coddington, spokesman for Spokane Public Schools, said students and staff noticed the odor of smoke at about 10:30 a.m, and pulled the fire alarm. The entire school evacuated and huddled outside while the Spokane Fire Department cleared the building.

The construction equipment vehicle segment is estimated to be the fastest growing segment of automotive heat exchanger market. Infrastructure development, especially in countries such as China and India, is supporting the growth of this market. Moreover, the construction sector in North America is also reviving, with governments taking initiatives such as the Build America Investment Initiative, Canada’s Economic Action Plan, and the National Infrastructure Plan (NIP) which will propel the demand for automotive heat exchangers in construction equipment segment.
Tomorrow I’ll post part two of this three part series, explaining standard maintenance and operation of HRVs. On Sunday I’ll post part three, explaining the most common HRV installation defects.
