Abstract:
Phase change materials have been applied into building framework to reduce
energy and fossil fuel consumption as well as make building sector more
sustainable.. In this study, the energy consumption assessment of lightweight twostorey
PCM-enhanced residential house placed at different eight locations (Helsinki,
Kiev, Saint-Petersburg, Moscow, Stockholm, Toronto, Montreal and Kiev)
restricted by Dfb climate region will be evaluated. The number of iterations were
performed by DesignBuilder software combined with Energy Plus engine by
applying eleven melting temperature ranges of PCM. The output shows that the
optimal PCMs have reduced the temperature swings up to 2.4 ℃. The performance
of PCM is not constant for the monthly assessment basis, hence every month
different PCM have performed efficiently. The optimal PCM variance is between
the thermal comfort zone (20-26℃) and depends on the geographical parameters.
For the indicator cities, the energy consumption varies from 2,81% to 5,72%. The
volumetric assessment may be shows that the efficient performance of PCM
increases with expansion of surface area combined with reduction of thickness.
Overall, the enhancement of PCM into building framework in residential building
located in Dfb climate region is feasible option.
