Criteria Analysis for Optimal Choice of Efficient Energy Use in Residential Buildings

Abstract

Around 11 % of the total energy consumption in the world goes to the residential and commercial sector, most of it being covered by petroleum, gas and coal. Not only they are not sustainable energy sources, but they also enhance the carbon footprint and increase the damage upon climate changes and environmental pollution. Financial burden and poor insulation issues are also to be considered especially at individual level. The present paper proposes some statistical processing of various data obtained in previous researches that will allow an educated choice of methods designed to increase the efficient use of energy in residential buildings, as people and also local authorities are reluctant of using expensive and revolutionary methods without a thorough documentation. The performed study will be based upon multi-criteria analysis and analysis of variance with several factors. The tools come from Excel data analysis, taking into consideration all factors and data that might influence an individual strategy of saving energy and money at the same time.
