The Building Energy and Environment Group (BEE Group) is an autonomous department of the International Center for Numerical Methods in Engineering (CIMNE) involving over 20 researchers (Physics, Engineering, ICT, Environmental Science and Statistics specialists). It was founded in 2001 and has two main offices, one in the GAIA building of the UPC Campus in Terrassa and the other in the EUROTRADING building besides the Cappont Campus of the University of Lleida.
BEE Group meets the challenge of employing our knowledge and experience to help users to get the best possible use out of the energy that they consume.
Our R&D activities are focused on:
Developing better building energy management by improving precision, providing faster response, setting up adaptive and predictive control and making buildings more responsive to users’ requirements and wishes.
Making energy data more useful to professionals and companies by reducing cost and increasing applicability and reliability through Big Data Analytics, personalized energy services and adaptive visual interfaces and mobile applications.
Making energy data more friendly to building users by selecting the most relevant information, by making control more appropriate and by personalising the experience.
We scout the science world looking for knowledge and inspiration
The BEE Group collaborates with national and international companies and institutions. As BEE Group, we understand that the goals and challenges we face could be achieved better if companies that are sensitive to the needs of society and researchers who develop cutting-edge innovations work together.

In Lleida we manage an experimental facility for testing of Ventilated Double Skin PV (VDSPV) façades.
LOT (Lleida Outdoor Test)
Is an isolated booth provided by a type of VDSPV façade structure and a climatic control system and air capturing, it is used for performing VDSPV façade testing in real scale and weather conditions.
TRE-L (Test Reference Environment – Lleida)
Is composed by three elements used for performing PV module testing under different stress environmental conditions.
Main objective of the test facility
The Lleida Outdoor Test cell (LOT) is a full-scale test facility for the comprehensive study of the energy performance of ventilated double skin facades in outdoor conditions. High quality data sets from the tests may be used for evaluation and modelling purposes. The installation allows for the analysis of the effect of the air gap width, air flow regimes and materials of the façade. It is also prepared for the detailed analysis of double skin integrated PV systems and their with HVAC systems. The façade may operate under natural and forced ventilation and the effect over the building is measured in a well-controlled test cell.
