Welcome to CERtuS


The web portal integrates all the knowledge gained from the CERtus project in an easy-to-use tool that aims to facilitate the planning and preparation of nearly Zero Energy Building renovation projects for municipal buildings. It is addressed principally to Municipalities and the public sector but it may be equally useful to the ESCOs, financing entities, policy makers and to all parties interested in Energy Efficiency and Renewable Energy systems integration in the building sector.The portal includes information on nearly zero energy cases studies, energy service models, innovative financing and tools to perform financial evaluations of nZEB renovation schemes, and, innovative building materials and HVAC systems.
