VENISE

The objectives of Title 1 of the Law "Grenelle 2" related to improving energy efficiency in buildings, and reducing their energy consumption and carbon content, are extremely demanding and do produce lower energy requirements. The need to reduce energy consumption is causing a profound reassessment throughout the building sector. The current design methods, mainly based on technical and economic optimization function by function, will not achieve these targets optimally. Combining powerful and expensive equipment for each function will not produce a low overall energy consumption. In addition, energy-efficient buildings offer the opportunity for air control to attain a new level of relevance. Air, despite its poor thermodynamic properties, has undeniable advantages (ubiquity, fine control with low power ...) when the energy requirements and power usage are reduced. This new context thus opens new avenues of research. The vision, not function by function but all simultaneously, focusing on air to satisfy the different regulatory needs by making the most of synergies between functions and the coincidence between the needs and availability of renewable resources. With this goal we propose to tackle this project. This involves developing a new design approach based on a multi-criteria method of optimization tailored to different segments of the building, and to extend the range and technical solutions to satisfy the demands of BEPOS and nZEB buildings. The consortium brings together a university laboratory, an industrial laboratory, two research centres, a consultancy, a manufacturer and an architect, all with recognised competencies in the area of energy efficiency in buildings. The project is fully aligned with the second theme of the RFP, and specifically the sub-theme 2.3, "multi-physics modelling, dealing with interior environments, comfort, environmental quality (noise and air quality) along with energy efficiency" with the proposed methodology, and the sub-theme 2.4, "Innovation in construction and renovation" due to the technologies that will emerge.
