Energy renovation of co-ownership properties: a perpetual movement
Under the government’s initiative, numerous changes have been made within the governance of co-ownership properties to encourage them to carry out energy and technical renovation. These legislative and regulatory modifications are implemented progressively based on feedback from the field brought to the Government. Thus, technical and regulatory changes occur approximately every six months since 2021, under the Climate and Resilience Act.
What are the latest developments? How to carry out energy renovation of a co-ownership property?
This live broadcast addresses the latest legal and practical developments for initiating energy renovation within a co-ownership property. Energy renovation is currently undergoing continuous evolution, whether technical, regulatory or incentive-based. Co-ownership properties are not exempt from this phenomenon, particularly as they are strictly regulated by the law of 10 July 1965 on the administration and conservation of buildings by co-owners.
The speakers, led by Pierre-Luc Naud, first address the new mandatory legal and technical documents within co-ownership properties. One of the major objectives of their establishment is to encourage co-owners to energetically renovate their building and to engage them in its maintenance.
The speakers then examine the process of energy renovation of a co-ownership property to successfully carry it out.
An incentive-based legal framework:
The live broadcast addresses the emergence of new fundamental documents within co-ownership properties, such as the Global Technical Assessment (DTG), the Multi-Year Works Plan (PPT), and the Collective Energy Performance Certificate (DPE collectif). The implementation schedule of these documents, their content, their objective, the voting on their implementation in the general meeting, how to obtain them and have them carried out are detailed. The consequences in the event of the co-ownership property failing to carry out these elements and practical points based on field experience feedback from Mr Gabriel Perrin-Brunier are also covered.
Key steps to successfully carry out energy renovation and available assistance:
The live broadcast addresses in the second part all the steps and methods to successfully engage co-owners in the energy renovation of their building. Information provided to co-owners, general meetings for voting on works, the carrying out of various assessments to determine the technical and energy condition of the building, and finally, the order of intervention of the various trades: client representative, project manager, assessor and thermal engineer, design office, SPS coordinator… as well as additional information on obtaining assistance such as MaPrimeRénov’ Copropriété are covered.
Valuable technical knowledge:
The two speakers, experts in their fields, cross-reference their knowledge within a fascinating discussion, allowing the approach to renovating a co-ownership property to be addressed from two different and complementary perspectives. The information provided is therefore valuable. It brings new and precise insight for the commercial agent, or the co-owners they advise, wishing to approach the energy renovation project with complete peace of mind.
