In one of our projects, a contractor offered to install “highly insulated garage doors.” Hopefully, after reading the definition of a thermal envelope, you can see why it makes little sense to pay a higher price for insulated garage doors. Even muddier they get, though, when you consider that a fence around a pasture is an enclosure. But an enclosure could also be something enclosed, as a photograph in an envelope. from publication: 3D Symbolic Visual Simulation of Building Rule. According to Merriam-Webster, an envelope is something that envelops, and an enclosure is, something that encloses. Other structures of the building, such as interior partitions, or elements that separate non-conditioned rooms from the outside, are not part of the thermal envelope. Download scientific diagram Applying building rules to define a building envelope. Learn the root causes of building envelope failures and how to avoid them. It’s important to understand that, in a passive building, the mechanical ventilation system is considered to be a fundamental part of the building envelope, instead of being considered part of the building systems. For this guide the building envelope also includes the below grade basement walls, foundation and floor slab (although these are generally considered part of the building's structural system) so that the envelope includes everything that separates the interior of a building from the outdoor environment. In fact, external openings that are suitable for a Passive House are deemed so because their individual energy balance is positive – in winter, they allow more energy into the building than what they let out. Within this structure, there are opaque elements such as the roof, external walls, internal walls that separate conditioned rooms from non-conditioned rooms, slabs on ground or external air, and so on.Įxterior windows and doors are also part of the thermal envelope, and play a very important role in the overall energy balance of the building, because they can provide passive solar gains through their glazing. The ‘thermal envelope’ of a building is the union of those structures that separate the conditioned part of the building (subject to being heated and/or cooled) from the outside (including neighboring buildings) or from other parts of the building that are not conditioned. In our articles about building energy efficiency, we often use the term ‘thermal envelope’: let’s define what we mean by that. Emerging Building Technologies’ two programs Green Proving Ground (GPG) and Pilot to Portfolio (P2P) enable GSA to make sound investment. Here are the published results, most recent on top. Thermal envelope – roof, walls, windows, and doors of a deep energy retrofit The GPG program, working with federal laboratories, has tested the following technologies in GSA buildings.
