“…2.6). Subsequently, PCM blended with blown fiberglass (Kośny et al 2010a) and building plastic foam insulations were introduced (Kośny et al 2007(Kośny et al , 2010bMehling and Cabeza 2008). From 2006 to 2007, ORNL performed a series of dynamic hot-box tests of wall assemblies containing PCM-enhanced insulations.…”

Ongoing improvements in building envelope technologies suggest that residences will soon be routinely constructed with low heating and cooling loads. The use of novel building materials containing active thermal components (e.g., PCM, subventing, radiant barriers, and integrated hydronic systems) would be an ultimate step in achieving significant heating and cooling energy savings from technological building envelope improvements. The key benefit of using PCM is that it affords structures improved thermal storage capabilities with minimal change to the existing building design (Sharma 2013). The main methods for incorporating PCM into building materials include the use of gypsum plaster boards and other structural boards, blending PCM with thermal insulations, and by macro-packaging. The thermal energy storage property of PCM is based on its latent heat storage capacity, given that large amounts of energy can be stored in a small volume. Therefore, the material containing PCM can absorb and release heat more effectively than conventional building materials. However, the selection of the PCM locations, PCM transition temperature range, and the amount of used PCM are essential for effective and durable use of the PCM-enhanced technologies, considering a relatively long life span of building envelopes.Present-day residential and commercial buildings are becoming more structurally lightweight, and concerns are been raised over indoor thermal comfort due to reduced thermal storage potential. A strong tension exists between the drive to build better efficient structures with less impact on the environment and the tendency to add more mass to the structure for thermal storage. These issues are further heightened by global climate change and the continual rise in energy cost. Without counting traditional arctic ice igloo constructions, the use of PCM in buildings began in the mid-1940s and this passive solar system with thermal storage capability was one of the first applications studied at that time (Telkes 1978;Frysinger and Sliwkowski 1987;. During the 1980s, bulk

“…The concept is based on incorporating PCM thermal insulation into the internal cavity of lightweight framed walls (see Kośny et al , 2007. This application is counter intuitive, because it deliberately restrains energy transport between the PCM and the conditioned space and the exterior environment .…”

“…It is important to remember that thermal characteristics of final PCM-enhanced products can be significantly different from initial characteristics of pure PCMs used for their production. Finally, building envelopes containing PCMs can be also tested in a full scale using dynamic hot-box testing method (see Kośny et al 2007Kośny et al , 2010a. Figure 1.11b, c shows two hot-box testing apparatus used in the past by the author for dynamic hot-box testing of walls and attics containing PCMs at Oak Ridge National Laboratory, USA.…”

“…6 In 2003, the first wall assembly utilizing PCM-enhanced foam was designed and constructed by the author. In 2004, the first dynamic hot-box test was performed on a wall containing two types of PCM-impregnated foam by the research team from Guardian, USA (insulation manufacture), Outlast, USA (manufacture of PCM-enhanced fabrics and foams), and Oak Ridge National Laboratory (ORNL) (Kośny et al 2007; see Figs. 1.4a and 1.5c).…”
