The RELAB Group conducts applied research on Renewable Heating and Cooling at both Building and District level. The activities involve experimental characterization of heating and cooling systems prototypes, numerical modeling of heat and mass transfer, dynamic simulations of building energy systems and energy planning of district heating and cooling networks. On a wider scale, from the local to the national level, the research group assists political decision-makers in paving the transition to a future clean and sustainable energy infrastructure through Energy Scenarios modelling. The RELAB expertise in renewables and energy saving extends to Life Cycle Assessment of products (goods and services) and of organizations, aiming at supporting companies and public entities in understanding and improving their environmental sustainability profile.
