As the growth of multi-family residential housing units has increased in recent years, so has the number of enclosed parking garages. Builders and planners recognize that tenants prefer enclosed parking garages for convenience and comfort. Such garages are a definite selling point in northern states where snow clearing is a major issue. However, with such enclosed parking areas comes a significant danger.
Even though enclosed parking garages are very attractive to tenants, keeping the air healthy should be a concern for building owners. Cars in enclosed spaces can produce high levels of carbon monoxide (CO), and diesel engine cars can produce high levels of nitrogen dioxide (NO₂). Both emissions are very dangerous and pose significant safety concerns to human life. Human health effects can vary significantly based on the state of health, age, sex and weight and exposure over time to low concentration levels can lead to respiratory problems, lung damage and neurological problems. Toxicity levels are well-documented and death can occur in a matter of minutes.
EP Sales is happy to announce that we have been appointed as the Opera Gas Detector Rep for the states of MN, WI, ND, SD and IA. Opera is based in Montreal, Canada and has manufactured gas detection products for over 35 years. Their products are typically used for vehicle emissions monitoring, combustion gasses, refrigerant leak detection and industrial health and safety. We see Opera as a nice complement to the extensive line of light commercial ventilation products that we offer through wholesale distributors in the upper Midwest.
Please check out Opera in the Vendor section of our website and give us a call or send your next gas detector project quote request to email@example.com.
The state of MN has been at the forefront of adopting residential building codes that incorporate energy efficiency designs for residential mechanical ventilation. These codes have additional provisions which address some of the serious side effects such designs can have on the home’s inhabitants and structural integrity.
Back in the early 1980’s, these energy efficient building designs introduced highly insulated air tight homes. These designs significantly reduce a home’s energy consumption but created adverse consequences that could not go ignored. Extensive research conducted over the past 30+ years was the driving force behind the current 2015 Minnesota Energy Code. Considered controversial by the builders and realtors, primarily due to the code’s cost impact on a home’s sale price, this code is also viewed as a showcase for all the advocates of the advancement of building science.
If you’re in the process of building a home and want to keep it filled with fresh, healthy air year-round, then you have an important decision to make – which ventilation system to add to your HVAC package.
The most effective ventilation options available for residential homes are HRVs and ERVs. In order to choose the right one for your home, it’s important to understand the differences between the two products.
Homeowners are increasingly relying on VRF heat pumps and ductless mini-splits to keep their families warm during the heating season. At the same time, commercial property managers are relying more and more on these devices as well, thanks to the ease of installation, simple controls and unparalleled flexibility that they offer.
VRF and ductless mini-splits represent some of the most efficient kinds of heaters on the market. Whereas propane and oil heating systems rely on expensive fuels to operate, these heat pumps produce indoor warmth in a cost-effective, environmentally friendly way.
However, heat pump mini-splits can be overtasked when dealing with subzero temperatures. These conditions cause HP’s to eliminate the efficiency that makes them so desirable and to produce less heat affecting the comfort of the living space.
Installing an electric duct heater for supplemental heating is one of the best ways to address this dilemma. The result is a far more efficiency in terms of the overall system’s Heating Seasonal Performance Factor (HSPF).
Electric duct heaters are a convenient, affordable and effective way to provide heat to a room or ventilation duct system. Professional HVAC contractors have used these devices in residential, commercial and industrial HVAC systems for many years.
The main idea behind heating with an electric duct heater is adding heat to the air inside the duct in an efficient manner. Electric duct heaters can be used in a broad range of applications, some of the most popular of which are:
When choosing an electric duct heater for your home or workplace, you’ll want to keep the specific application in mind when deciding the model you need.
When it comes to residential and light commercial heating, ventilation and air conditioning, a fast-growing market segment is quickly developing into an industry-leading trend. Ductless air conditioners, also called mini-splits, are increasingly replacing the large, bulky window-mounted systems of yesteryear. Is this a passing fad, or are there real benefits to be enjoyed by installing one of these systems in your home or workplace? Read on to find out.
The main difference between these new systems and traditional window air conditioners is that they are smaller, more efficient and more flexible when it comes to mounting and placement. Mini-splits allow homeowners to selectively heat and cool individual rooms according to their occupants’ desires by connecting a single outdoor unit to multiple indoor air controllers.
If you have a high-powered, commercial-quality cooktop installed in your kitchen, chances are you also have a makeup air unit installed in your home. This device compensates for the amount of air being pushed out of your kitchen’s extractor and breathes fresh, room-temperature air in from outside. Makeup air units are typically automatic—unless you had yours recently installed, you may not even know you have one, but you’ll notice if it breaks down.
If your cooktop comes with a large extractor hood that sweeps out odors and contaminants from your home, your makeup air system is what’s responsible for replacing the lost air. Without it, your home would be depressurized and the kitchen hood would soon be unable to push the air out. The fumes would collect inside your house—creating a dangerous environment for you and your family.
It’s no secret that U.S. homeowners are becoming increasingly attracted to the idea of installing high-powered, commercial-quality kitchen equipment in their homes. The widespread availability and increasing affordability of these devices makes them a common sight in American kitchens.
At the same time, residential building contractors are designing homes that are more airtight than ever before. As a result, house depressurization and its associated risks are on the rise, making reliable makeup air solutions a necessity for many households.
Heating your home with a heat pump is energy efficient and cost-effective. When dry indoor air becomes a problem in winter, however, you’re likely to find that the central humidifiers that work just fine with fossil-fuel-fired furnaces aren’t as effective when used in conjunction with a heat pump. Fortunately, a steam humidifier may be the solution to the problem.
