Climate and Energy-Adaptive Design & Engineering

To guarantee optimal bioclimatic and energy-adaptive design for our projects, given their programmatic objectives and unique locations, we combine analysis methodologies at different scales with highly advanced and precise calculation and simulation tools. 

At the urban level, we draw up energy strategies for new or renovated neighborhoods. Each strategy begins with a process of characterization of needs, which entails collecting existing consumption data or estimating ratios. In the case of new builds or renovation projects, we estimate energy requirements by setting targets for the thermal performance of buildings. For high-stakes projects, we execute dynamic energy simulations (DES) across entire districts to calculate the volume of energy consumed and the power demand for multiple variants. This data is then used to choose from all available energy sources.

To choose the most appropriate energy supply, we cross-reference needs with local sources. Our choices are based on multiple criteria: carbon footprint, health impacts, nuisance, impact on the thermal environment, “renewability” and sustainability of the resource, investment and fees, and so on.

At the building level, whether for new constructions or renovation projects, our approach is underpinned by three pillars: the design of exterior spaces, envelopes and morphology, and interior spaces.

The design of exterior spaces factors in the problems of winter sunshine, heat islands, and the overall lowering of temperatures to create a more comfortable environment thanks to shade, wind, and the presence of water.

From the point of view of envelopes and morphology, these elements act as a climate-adaptive transition skin between inside and outside. Our design approach for these is based on a deep-dive analysis of the performance of opaque and glazed walls, as well as the use of materials with phase-shifting properties and high thermal inertia. Attention to thermal bridges contributes to energy efficiency, creating a protective envelope with limited winter losses and summer gains.

Third and last, the design of interior spaces is shaped by the validation of fluid principles (mechanical ventilation systems, emitters, etc.). We analyze partitioning and cross ventilation, and study natural ventilation conditions to ensure interior environmental comfort and elevated hygiene standards, while promoting the integration of natural light.

We complete and corroborate this global approach through RE2020, dynamic thermal simulation (DTS), DES, internal and external computational fluid dynamics (CFD), and light studies. For the most ambitious projects, we provide energy commitment studies. In addition, we examine available and consistent energy supplies, based on renewable energy potential among other factors. We also monitor performance, from design through installation, notably through technical validation processes. Finally, we track energy consumption on site to ensure responsible management throughout the construction process.

By taking a holistic approach, we demonstrate our commitment to designing buildings that are functional, sustainable, and adapted to today’s climate challenges.

We believe that all factors and elements are interdependent, and that the success of a project lies in co-designing it with all the stakeholders and bringing together all the different specialties required. Energy design is therefore approached from architectural, carbon, acoustic, economic, and landscape perspectives to ensure a coherent approach and practical feasibility.
