The wellbeing of European citizens is closely related to the indoor conditions. Comfortable and healthy living conditions for all citizens are a crucial part of the modern European society but difficult to attain due to the variability of typology and as well as the age and overall condition of the building stock.


It is a pressing need to improve indoor conditions in an energy efficient and sustainable way due to the well documented effects of climate change, that have already been experienced globally.


PRELUDE will facilitate the transition to clean energy by combining innovative, smart, low-cost solutions into a proactive optimization service. The project is focused on assessing the right level of smartness necessary for any given household and then providing the optimal tools according to the needs of the user.

  • It is designed to be versatile and adapt to the engagement, monitoring and automation level of the building;

  • Passive solutions, such as natural ventilation and cooling, will be prioritized through a free running strategy. Predictive maintenance will be implemented to reduce costs, emphasizing RES (Renewable Energy Sources).

  • Big data and advanced analytic tools will be used to facilitate flexible building side demand and ease the integration into district heating and electricity grids. Proactive optimization will be achieved through data predictive control.

The system is comprised of three main components:
