Novel Building Envelope Design for Increased Thermal Performance

In 2014, more than 40% of US primary energy and 70% of electricity was consumed in residential and commercial buildings, resulting in annual energy costs of more than $430 billion. The envelope of the building, which refers to the external walls, windows, roof, and floor of a building, is the thermal barrier between the indoor and outdoor environment and one of the primary determinants of energy use to maintain indoor comfort.  Through its online crowdsourcing platform, JUMP, Oak Ridge National Laboratory is looking for ideas to improve the performance of the building envelope.  The challenge is to develop a new material or an installation method that uses readily available products to improve the thermal performance and air tightness of a wall assembly, without compromising the durability of the wall assembly.

Fireplaces are one of the biggest sources of energy loss in the home.  Many people use old buildings and homes for their "home offices".  The fireplaces are no longer being used for heat, as when first installed.  Wood burning fireplaces are very dirty and toxic, as well as sucking the heat out of the area.  Most gas fireplace have an open vent to the outside, creating even more energy loss in both winter and summer.  The constant air exchange created by fireplaces, causes heat loss in the winter and hard working air conditioning in the summer, as it tries to keep up with the heat and humidity being sent down the chimney.

Thanks Sarah

Crowdsourcing can be a powerful tool. And the JUMP program is a good use of DOE funds, IMOP. 

A wall that used less labor, consumed less costly materials, leaked less air, insulated better; which part of those incremental changes wouldn't help drive sales?

We offer an insulated roofing tile that transforms the attic into a conditioned space.
Lowers energy footprint up to 35%.

With Home Performance nearly irrelevant in the marketplace, what problem does this solve?

How about solving the sales problem first?

Once Home Performance is mainstream, THEN incremental improvements can have meaningful impact!
