Phase Change Material (PCM) – comparing embodied impact versus operational energy savings

The embodied impacts of Phase Change Materials (PCMs) can be calculated in eToolLCD by either an EPD from the manufacturer or one of our library materials as a proxy. The thermal performance benefits will need to be captured by the energy simulation software. Final heating/cooling loads (MJ/m2/year) can be entered in eToolLCD to allow the user to understand the net benefit when comparing the embodied impact from materials / installation / maintenance / end of life versus the thermal performance improvement / heating/cooling energy savings. The results will be largely influenced by the climate conditions, the design overall thermal performance and the PCM product selected.
