Testing reflective insulation for improvement of buildings energy efficiency

Abstract

AbstractReflective insulation stands as an alternative to common building materials used to reduce a building’s heating and cooling loads. In this work, an experimental prototype chamber facility has been designed and constructed at the campus of the Technological Educational Institution of Halkida, located in an area of climatic zone B in Greece, aiming to the evaluation of reflective insulation’s performance. Reflective insulation is a part of the test room wall construction, specifically, heat insulation material of the vertical wall construction all directions (North, South, East, West), and temperature and water proofing element of the roof. Measurements were obtained for both winter and summer periods. Results indicate that the existence of reflective insulation during summer period averts the overheating at the interior of the experimental chamber, while during winter the heat is retained in the chamber.
