Development of MERIT and Normalization Factor for Different Operating Hours for Building Energy Intensity (BEI)

  The JKR-UNDPs Building Sector Energy Efficiency Project(BSEEP)in Malaysia is aimed at reducing the growth rate of GHG emission of the building industry in Malaysia.Component 4 task in BSEEP in 2015 was to develop a document allowing the Malaysian building industry to compare energy efficiency of different buildings in a fair manner.The MERIT is one of the output by this project.MERIT is a proposed methodology for gathering,interpreting and the use of data for the purpose of obtaining an accredited Malaysian Energy Efficiency Rating of Building for Offices(MERIT for Offices)for existing buildings using 12 months of actual data.MERIT is based on the computed Building Energy Intensity(BEI)in kWh/(m2.year); an index that is commonly used in South East Asia.During the development of MERIT,a study was made on the linear normalization of operational hours of office building that is commonly practised by the building industry in South East Asian region.It was found in this study that a linear normalization significantly misrepresents the BEI of an office building operating 24 hours daily versus a building that is operating only 8 hours a day from Monday to Friday.A linear normalization was unable to capture the effects of building thermal mass and base-load effects of buildings with different operating hours.Further studies establish that a logarithmic fit is more appropriate method for normalizing operational hours of buildings BEI.This will be the 1st tool in South East Asia that will use a logarithmic normalization methodology to allow better representation of the BEI due to different operating hours in buildings.
