SAGECO is a thermal engineering consultancy specializing in energy-saving advice. Patricia Lesage, who founded the company over ten years ago, offers her support services to companies, public institutions, developers, builders, social landlords, local authorities and condominium managers. We also work with architects, and are happy to take on private clients. The cost of SAGECO's intervention is not to be considered as an expense, but rather as an indispensable added value, a feasibility study to prioritize and choose your work, and can be taken into account within the framework of aid schemes.

Analyze the building's needs. The contribution of a design office to a construction or renovation project is essential to its technical and economic success. The thermal study stage in a renovation project gives you an overall picture of your building's state of performance, from which Patricia Lesage and her four-strong team can show you what can be done, prioritizing work according to your budget: insulation, window replacement, choice of heating and ventilation system, reducing thermal bridges, limiting humidity problems, ensuring air quality... SAGECO's reading of your estimates is essential to assess their relevance and accuracy. SAGECO also draws up a multi-year works plan (PPPT), essential for condominiums with more than 200 lots.

SAGECO is involved in a number of aspects of the construction process, including the calculation of Bbio (bioclimatic requirements) for building permits issued to builders and developers, in compliance with the RE 2020 standard, and air-tightness testing of buildings. Patricia Lesage regularly trains in all aspects of building energy performance, and has become an expert in the physical knowledge of buildings. A member of the ICO association (Ingénierie Confort Objectif 2050), which brings together design offices, manufacturers and installers, Patricia Lesage has signed up to the charter designed to define common-sense rules for successful energy renovation in condominiums.

A partner of Patrick Branchu & Associés Architectes, Patricia Lesage is involved in feasibility studies for both new-build and renovation projects in condominiums. She brings her expertise in thermal analysis of buildings to bear in proposing sustainable, comprehensive solutions for the energy renovation of private condominiums. From technical and financial feasibility studies to step-by-step support for property managers, right through to works supervision.

RE 2020 - Since January 2022, RE 2020 has meant that tomorrow's buildings must be designed differently. Sageco is well aware of these changes, and can help architects meet these new regulations.
