The role of green roofs on reducing heating and cooling loads: a database across Chinese climates

Journal Article


Abstract


  • This paper aims to use detailed modelling techniques and develop a database for assessing in a quick and easy way

    the energy performance of green roof designs across a range of Chinese climates. The focus is on heating and cooling

    loads by calculating indoor temperatures using the EnergyPlus simulation tool. The study covers 5328 configurations

    by varying model parameters such as location, climate, seasonal periods, glazing type, wall insulation levels, roof

    insulation, soil thickness and condition, and vegetation density characteristics. It was found from the results that

    green roofs can offer significant energy savings for heating and cooling loads if they are applied on roofs without

    insulation but only limited energy savings where heavy insulation on the roof is also applied. This database can prove

    to be a useful tool to the practitioners who want to perform rapid assessments of the potential energy savings that

    could be gained from a green roof installation in a Chinese location.
