Our approach to successful energy renovation

There are many parameters to take into account when preparing an energy renovation project. At Assysto, we believe that good preparation must be based on 4 pillars:

  • Precise data on the property
  • A simulator to explore the multiple combinations of renovation actions based on a reference thermal calculation engine
  • Compliance with good renovation practices for lasting results
  • A 3D model to help the client visualize the result of their renovation scenario
Perform iterations with an energy simulation engine using 3D model data

DPErama: our solution to master the “DPE” dimension

In France, public policies for energy renovation of housing are based around the DPE, the “Diagnostique de Performance Energétique” (Energy Performance Diagnostic). The DPE is carried out by an accredited technician using certified software. The result of the diagnosis of a home is a letter from A (very good) to G (poor efficiency). A poor classification implies many obligations and prohibitions. For example, since January 2023, it is no longer permitted to rent certain properties classified G.

DPErama is a solution that automatically collects the data used to create a DPE, and integrates the regulatory thermal calculation engine to simulate renovation work. For each renovation action, it allows you to immediately know its impact on the DPE classification, and to estimate the savings in terms of energy consumption and CO2 emissions. The solution also indicates the total cost of the renovation scenario. DPErama calculates optimized scenarios, which make it possible to achieve any DPE classification, at the lowest cost.

Our 3D model creation service offer

To support your thinking during an energy renovation project, Assysto offers a digital twin creation service. It is common for old buildings to have plans that are not available or are not up to date. Assysto creates 3D models, even if no plans are available. Assysto has developed a mobile application that allows you to very quickly collect the data needed to create the model.

3D models are produced in BIM IFC (Building Information Modeling) format. This open format is the standard in architecture and construction. The model is much more than a 3D representation of the property: it is a complete database. The IFC model contains for each object its geometry (if it has one) and the information attached to it (for example the cost, information on the manufacturer, etc.).

Whenever possible, Assysto integrates the data from the available sources, whether coming from public or private repositories. If you have specific needs, contact Assysto. We will study how to insert your data into the BIM IFC model.

DPErama is used by public and private landlords to plan and optimize energy renovation works. It is also used by renovation companies in order to get good confidence that the target DPE ranking will be reached.
