Growing Importance of Energy Efficiency in Building Sector

The purpose of this article is to go deeply into the knowledge of energy consumption by the construction sector. The unproven tendency to optimize all energy processes in infrastructure construction is what is intended to be successfully demonstrated in the article. It describes concepts such as embodied energy, lifecycle-assessment and the possible results of using BIM software. A survey was developed to check the awareness of the construction market players about this topic. The results were analyzed with an artificial neural network that predicts the market trend for the future. Energy measurements of the entire life cycle of construction projects (buildings or infrastructure) and the use of recycled materials from demolition or other industries can be the future in a few years and all the policies in Europe are taking in account this idea. After talking with all survey respondents that work in the construction sector as service, machinery, materials or consulting companies, the conclusion reached in the article is that the energy consumed in the construction processes should be taken into account in a mandatory way. 146 Jarosław Górecki, Sergio Morales Calleja
