Review on Building Energy Performance

Abstract

Today, fossil fuels account for 44% of the world's energy production, endangeringbothhuman health and the natural world. The construction industry is one of the major energyusers, with a significant amount of the energy used being regarded as superfluous, accordingto a recent analysis of global needs for energy usage within different energy usage sectors. This is a result of inadequate management techniques and the use of preventative measuresagainst excessive energy use. To address needless use of energy and guarantee optimal livingconditions for sustainable urban areas, research in both academia and industryhasconcentrated on several strategies over time. This study presents a reviewof existingliterature on building energy efficiency. The study extensively discussed energy performance, building data acquisition, and strategies for twin-building energy simulation. The studyfurther identifies strengths and weaknesses in each aspect of the building energy performancediscussed.
