Cythelia carries out complete assessments using the certified « Th-BCE » calculation method to check conformity with the 2012 Building Energy Efficiency Standards .

We produce the documents that you need to submit to your local building department when applying for a permit, as well as detailed reports to give to the building inspector when issuing the work completion certificate.

To streamline the assessment process, we provide a file that needs to be completed and which lists the necessary elements for conducting the assessment. If your project has not yet been clearly defined, we can guide you early on and ensure that you make the right choices when designing your project.

Our OPQIBI 19.05 and Promotelec certification bears testament to our expertise in thermal building design.

Conformity assessment – Stage 1: Compile the documents required to perform the conformity assessment
To simplify the process of compiling the documents that we need to assess your conformity with the 2012 Building Energy Efficiency Standards, Cythelia has produced a file that we will send you free of charge. Click on the following link to see a preview: « 2012 Building Energy Efficiency Standards conformity assessment: customer file« .
Using this file, we can carry out your assessment as smoothly as possible while guaranteeing a fast turnaround time.

Conformity assessment – Stage 2: Conduct the assessment
Once we have received the documents specified in the customer file, we create a model of the building and perform the assessment using the Th-BCE calculation method. If necessary, we can advise you on insulation and heating systems.

Conformity assessment – Stage 3: Validate the project
The results of the assessment will determine whether or not your building conforms to the standards. If the outcome is positive, we will provide you with the reports to be submitted to your local building department when applying for a permit. A more extensive assessment report will be issued for your work completion certificate. The inspector will use this document to ensure that the actual systems installed match the choices made during the assessment.

Conformity assessment – Stage 4: Support for satisfying regulations
If your project fails to conform to regulations, Cythelia will provide you with advice for cost-effectively reaching the level required by the 2012 Building Energy Efficiency Standards (technical / economic optimization).

The objectives of the Building Energy Efficiency Standards (especially the 2012 version) are as follows:

• Assess a building’s conformity with national requirements
• Compare different buildings based on fixed criteria and assumptions
• Guarantee a minimum level of performance on a national scale

The regulatory calculation is not intended to design or size a building, but instead check that it achieves a minimum level of performance. Therefore, you should not use thermal regulations as an example or reference of high-performance buildings in your design process.
