Monitoring and modelling the energy efficiency of municipal public buildings-case study in Catalonia

摘要

Energy-efficiency benchmarking can be used to monitor changes in overall efficiency of buildings. Benchmarking models, based on energy-efficiency indicators are valuable tools for both public and private stakeholders because they allow an improvement in the building energy management. For the last decade, some governments have used these tools to define their building regulations (M. Santamouris, 2005. W. Chung 2005). This paper tries to goes further, integrating a benchmarking and a model!ing process, in the same energy efficiency analysis. The connections between the energy-use intensities (EU Is) and the characteristic building factors are modelled using network techniques. The process is divided in two stages: the data acquisition stage, and the benchmarking and modelling stage. The benchmarking and modelling stage is focused in the adjustment of these EUIs within the climate conditions (with a degree days modified method) and the develop-mentofaprediction model forcalculatingthe relationship between these climate adjusted EUI and the significant factors of a building. In order to validate this methodology, an application to schools in Catalonia is presented .
