K-Value, U-Value, R-Value, C-Value

In most applications, the primary feature of a thermal insulation material is its ability to reduce heat exchange between a surface and the environment, or between one surface and another surface. This is known as having a low value for thermal conductivity. Generally, the lower a material’s thermal conductivity, the greater its ability to insulate for a given material thickness and set of conditions. If it is really that simple, then why are there so many different terms, such as K-value, U-value, R-value, and C-value? Here is an overview with relatively simple definitions. https://news.jm.com/blog/hvac-insulation/k-value-u-value-r-value-c-value

Add Efficiency to Your Commercial HVAC System with These Small Changes

The average commercial building attributes 40% of its energy costs to heating, cooling, and ventilation, according to estimates from the US Department of Energy. For the typical office building, that equates to 7.5% of its annual operating expenses, on average. Finding efficiencies in your facility’s HVAC system can result in significant savings on operating costs. But it can also yield even bigger returns in non-energy benefits. Improvements in comfort, indoor air quality, and equipment reliability can all be achieved with HVAC maintenance and upgrades. No matter your industry, by improving your HVAC equipment you’ll find a way to improve your…

The Curious Case of the Imploding Windows

In 2008, a Dutchman named L. Korn found himself in Toronto buying windows for a house he was building back in the Netherlands. Unavailable at the time in Europe, the quad-pane insulated glass he wanted could be ordered from a Canadian manufacturer, and Korn was ready to do business. Korn placed an order for 193 insulated glass units — just the glass, no frames — with Eco Insulating Glass Inc. of Mississauga, Ontario in April 2009. The $40,400 order went to a warehouse in New York and from there was shipped by sea to his house in the Netherlands. Carpenters…

Let’s Mine Our Landfills

This post originally appeared at Ensia. The car tires were abundant and easy to spot. As were newspapers, made from trees with tough cell walls. Then there were tons of soil, aged and packed with decomposed garbage from the 1980s, when Madonna belted out “We are living in a material world, and I am a material girl,” and Star Wars brought us a future that didn’t seem to include trash cans anywhere. At the closed Perdido Landfill in Escambia County, Florida, they’re digging into the past to eliminate old garbage that could contaminate groundwater and to clear space for future…
