Building geometry and development form optimisation in terms of the energy efficiency

Abstract

The construction sector consumes around 40% energy for the purposes of heating. The policy of sustainable development that has been implemented for many years also transfers to actions in the construction sector. The European Union is introducing a standard of buildings with a near-zero energy demand. This standard can be achieved only by altering the manner of the design, construction and use of buildings. Such parameters like geometry or the placement of buildings relative to each other and the structure of their layout on the site, on the scale of groups of buildings, also have an impact on the energy consumption. The goal of this article is to assess the improvement of the effectiveness of actions taken in order to lower the energy demand for heating of designed buildings meant for permanent occupancy. The assessment takes into consideration the conditions of sustainable development. The analysis covers the impact of the geometry of a building and development structure on the energy balance.
