The energy transition is a priority. That's good news, because CO2 and energy are at the heart of our concerns. At Signa-Terre, we develop integrated solutions for measuring and projecting the CO2 impact and energy consumption of property portfolios. The skills of information technology, architecture, engineering and energy management in the built environment are combined in a unique expertise to simplify the energy and technical monitoring and planning of our clients' properties. In this context, we develop a set of innovative software solutions that allow owners and property managers to have a clear and synthetic view of the energy, asset, legal and financial aspects of their property portfolio. For single buildings, we are involved throughout the renovation process, from the initial concept to the implementation of the project, including the monitoring, control and optimisation phases.
