Sensitivity analysis of cost-effective recommendations for improving building energy efficiency

Buildings are the biggest energy consumers ; this energy is partly wasted because buildings constructed several decades ago do not meet the energy efficiency requirements of current legislation. Many of these exiting buildings will continue to be used for many more years and therefore they will continue to needlessly consume massive amounts of energy for heating unless their energy performance is improved. Stated issue with exiting buildings is partly solved by implementing energy certification of buildings procedure. According to Ordinance on energy audits of construction works and energy certification of buildings energy performance certificate must provide information on the energy efficiency of building and cost- effective recommendations on how to improve building energy efficiency. However those recommendations do not address problem of changing fuel rates when calculating simple payback period of proposed recommendations. This research clarifies how various fuel rates can affect the simple payback period of proposed construction measures for improving energy efficiency of building. This case study is done by using sensitivity analysis on data obtained from several buildings which have undergone a process of energy certification and for which recommendations for improving building energy efficiency and simple payback period already exits.
