COATINGSPRO JULY 2016 17 such as ASHR AE 90.1 while taking into account heat fows through an enclo- sure assembly despite the standard 's lack of potential improvements to building envelope assemblies beyond the continuous insulation prescriptive compliance path. Due to new products and baseline energy performance data, construction details are now available for insulating structural steel and concrete beams. Tey help give project teams new freedom for the creative design of LEED buildings while addressing the building's condensation resistance and its energy efciency within the building envelope. Recent studies funded by one coating manufacturer show that fuid-ap- plied insulated coatings can assist project teams with condensation reduction and whole building energy efciency when applied to structural building elements — or thermal bridges — that bypass the insulated portions of the building envelope. For example, an acrylic coating can stop the process of heat convection via a steel beam; once this is combined with an insulative coating, it also reduces convective heat loss. Te fndings were very promising for various common construction details, including structural steel and concrete assemblies bypassing the thermal insulation. Insulative coatings, which can help reduce heat fows, are infused with fllers to produce a low-conduc- tivity material that can be applied while in its fuid form. Fillers can be ceramic or glass spheres, which can provide thermal conductivity in the 70- to 100-mW/mK range. Newer fllers, such as aerogel particles, can provide a thermal conductivity as low as 35 mW/mK. Te use of insula- tion coatings for mitigating thermal bridging is a relatively new application in architecture. LEED, Energy Efficiency, and Healthy Interiors Reducing heat f lows in a building can be an important aspect of ther ma l break coatings.
