California Heat Study (video)

Hotel rooms make the perfect laboratory for measuring, monitoring and testing the effectiveness of this technological advance in window efficiency. Two identical spaces, two identical, calibrated, Packaged Terminal Air Conditioning Units (PTAC), and two identical oversized windows with direct westward exposure for maximum solar heat gain. This test was designed to determine the ability of the radiant barrier to control the behavior of both thermal and radiant heat gain during warmer months. Thermal heat being the migration of the warm ambient air temperatures to a cooler space and radiant heat produced from the suns energy directly hitting and heating a surface. Thermal...

Canadian Winter Study (video)

Extreme temperatures during a Canadian Winter proved to be an excellent test for the ability of Solar Comfort to efficiently reflect thermal radiant heat before it has a chance to migrate through windows. Canadian Winters can be exceptionally frigid and the weather during our cold weather hotel study was no exception. While the test ran for nine consecutive days, the highest the temperature was 28º F and the lowest was -5ºF’. Those were perfect conditions to demonstrate how well the radiant barrier material was able to reflect the heat pumps’ thermal heat back inside the room, slowing the natural migration of heat to the extremely cold window and then out into the...

Hotel Cooling (video)

The first few hours of the California Hotel Heat Study revealed how Solar Comfort can potentially cool an existing room over 4 times faster than a room without. Our test results confirm that. Although it is just one segment of the California Heat Study we found these findings significant enough to warrant its own short video clip. Guests of the hotel had complained that the rooms were still hot after more than an hour of cooling. Hotel policy, as an efficiency measure, was not to cool the rooms prior guest check-in. There was no setback on the thermostats so it wasn’t unusual for the rooms to reach 90 degrees. At the electrical panel, power use monitoring equipment...

Summary

Radiant Barrier for windows is a relatively recent entry into the arena of energy efficiency yet it grapples with the one of the largest areas of energy use, the constant migration of heat in and out of buildings through glass. Radiant heat movement accounts for 80% of all heat movement, so it would stand to reason that controlling that migration would increase efficiency. Balancing interior spaces through less transference of heat during both Winter and Summer, creates a stable and comfortable building envelope. An efficient building envelope is the base from which all other efficiency measures should be evaluated.
