Building envelope
Condition of walls, openings, roof and floors.
Local service
What the request can cover
In Brussels, the project must be linked to the correct municipality and checked against Brussels-Capital Region rules. Site access, adjoining properties, changes to the external appearance and any permit requirement remain points to confirm before the solution is fixed. An energy audit and renovation plan starts with the building envelope, current use and project priorities. The aim is a coherent sequence of work that still has to be checked against regional requirements and the actual condition of the property.
This page provides a preparation framework. Scope, feasibility, timing and any required steps are confirmed for the building concerned before commitment.

From first contact to proposal
Scope
Address, building type, use and priorities are clarified before a visit is proposed.
Survey
Dimensions, substrates, access and relevant junctions are checked on site when the project requires it.
Proposal
The solution, options, installation and finishes are described in a documented proposal.
Organisation
Manufacture, site access and handover are planned after the scope has been approved.
Reserved slot — local evidence
Local evidence and case study
Project and photographs awaiting validation
The template is ready for a local case study. Exact address, photographs, scope, results and permission to publish must be checked before release.
FAQ
Read the FAQ
An initial review uses the observed problem, the known age or history of the elements, available photographs and relevant dimensions. Isolaris separates symptoms from possible causes and does not confirm a technique, timetable or outcome before the necessary information is available.
Is this an accredited energy audit?
This page describes support for planning renovation work. For a regulated audit or PEB/EPC certificate, verify the professional’s accreditation and your region’s requirements before commissioning it.
What does an assessment cost?
The price depends on the building, available information, visits and requested deliverables. Scope and fees should be confirmed in writing.
Which work should come first?
The order depends on defects, moisture, ventilation and the junctions between different works. It must suit the building; there is no universal ranking.
What savings or grants can I expect?
Savings depend on the building, use, climate and execution. Support depends on current regional rules. Scenarios are neither a savings guarantee nor confirmation of eligibility.
The quotation depends on the survey, access, safety, interfaces with other building elements and finish choices. Permits, support schemes and regional obligations can change and must be checked against the official sources applicable when the project is prepared; they are never presented here as guaranteed.
