Specific studies

Very high energy performance buildings

In addition to regulatory EPB studies, RYA offers a wide range of energy studies.

RYA provides a comprehensive service for the construction of buildings with very high energy performance.

Research and certification for low-energy, passive, zero-energy, or positive-energy buildings using PHPP software.

This includes, among other things: sizing the building envelope and openings; optimizing ventilation efficiency and airtightness; defining internal heat gains, solar gains, and shading; verifying summer overheating; and designing high-performance structural details.

RYA, which has also designed passive housing projects as an architecture firm, is your go-to partner!

Buildings that are comfortable in the summer

RYA creates 3D models of the project and performs dynamic thermal simulations of temperature changes for each critical space, taking into account all relevant parameters: the building’s geometry and site layout, sunlight and shading, wind direction and speed, internal and solar heat gains, airtightness, solar shading, and cooling techniques, among others.

This dynamic simulation study enables the development of a concrete and effective strategy to combat overheating in the summer.

This study is mandatory as part of the certification process for passive commercial buildings (daycare centers, schools, offices, multi-family housing, etc.).

Analysis of structural joints

A construction joint (also known as a thermal bridge) is a point in the building envelope where additional heat loss may occur. It is therefore important to verify that these joints do not cause excessive heat loss and/or problems with condensation or mold.

The design of high-energy-performance buildings requires a detailed analysis of each connection. How construction joints are modeled can significantly affect the results of the overall analysis.

Audits & parametric studies

Would you like to estimate the energy savings your project will achieve during the design phase?

Together, we’ll review your project to identify the various possible or desired improvements to the building envelope and/or building systems. A parametric study will provide you with an estimate of the relative and cumulative savings from the different measures.

Are you committed to moving forward with the project but don’t have an architect yet?

We can handle the entire architectural scope of work and guide you from the design phase through to project completion. RYA has a full-service team.

Personalized support

Whatever your needs may be regarding a building’s thermal performance and technical systems, RYA uses or develops practical tools to meet your needs and offers ‘customized services‘.
