Abstract


  • A passive means of lowering the energy demand of buildings is the application of green roofs. The

    complexity between heat and moisture exchanges in green roof layers and the large variations

    of green roof types make the need for experimental or simulation assessments necessary for

    quantifying the energy benefits from green roofs. The current treatment of green roofs in simulation

    programs is either over-simplistic, for example by ignoring heat and moisture exchanges such as

    evapotranspiration, or the more advanced models have limitations and require inputs that are

    rarely available in practice. In this paper a combination of experimental and modelling techniques

    are used to assess the potential heating and cooling load reductions from the application of green

    roofs in the subtropical climate of Ningbo in China. The method provides a generalised energy

    performance assessment of green roofs in Ningbo by overcoming the limitations of existing green

    roof simulation models.
