A Building Retrofit Optimization Model Using Notch Test Data

摘要

Retro?tting buildings with energy-e?cient facilities is acommon method to reduce the energy demand in thebuilding sector (Fan and Xia [2015b], Wang et al. [2014]).Aligning with the purpose of reducing energy consumptionof buildings, a rating system energy p erformance certi?-cate for buildings (EPC), is developed by the governmentof South Africa1. The green building policy is of great helpto drive the owners or managers of buildings to improvethe energy e?ciency of the buildings by retro?tting themwith energy-e?cient facilities and thereafter make sure thebuildings can get an energy rating from EPC. The EPCrating system has seven levels, ranging from Grade A (veryenergy e?cient) to Grade G (not energy e?cient). Therequirements of obtaining a certain rating from EPC aredescrib ed in Table 1, in which Eris the reference2.
