Role Of Building Automation Related To Renewable Energy In nZEBs

Published: 10/09/2014

The EU directive on the future energy performance of buildings (EPBD) requires that by end of the year 2020 all newly built buildings comply with a standard called ‘Nearly Zero-Energy Building’ (NZEB). NZEBs combine a nearly zero or at least very low energy use with a significant share of renewable energy.

Compared to actual new building practice, nearly zero energy buildings require a well mastered equilibrium between minimized energy losses, internal gains and the remaining energy needs. In most cases control systems will be necessary to reach this equilibrium, especially in non-residential buildings.

In this study for the Leonardo ENERGY initiative, Ecofys examined the potentials of building automation in the context of future nearly zero energy non-residential buildings. The study considered the demand characteristics of different buildings types at different climate conditions as well as the supply characteristics of on-site renewable energy and the possibilities of energy storage.
