Building & Climate

Connecting Inside and Outside

Most modern buildings are no longer monolithic systems that exist independently of the environment. Due to influences such as wind, solar radiation and energy exchange, the interactions extend to neighboring buildings.

Today buildings are designed with awareness of climatic conditions and often allow zones of smooth transitions between the inner parts of the building and the outdoors.

Estimation of the energy and exchange processes between open space and indoor environment

A group of buildings, together with urban surroundings such as green areas and traffic infrastructure, form a complex and dynamic landscape.

In order to understand the contribution of individual buildings to the urban microclimate system and to assess the energy exchange between the interior of the building and the outside microclimate, all these elements must be accounted for in an integrated simulation framework.

The holistic and high-resolution approach of ENVI-met allows you to simulate the microscale urban metabolism as a complex system as well as the energy fluxes at the façade scale of a single building.

Building Physics

The microclimatic conditions in the immediate vicinity of a building have a decisive influence on the energy conditions of the building system. To understand how the dynamics of the urban climate impact a building’s energy consumption, an integrated model of building physics is essential.

ENVI-met enables the development of sustainable design solutions, from the analysis of the reflectivity of a single construction material to the impact of a building arrangement at a neighborhood scale.

High-resolution simulation of façade temperatures and wind speed patterns

The trend towards urbanization has made it increasingly important to study the impact of urban climate on thermal warming at a regional and global scale, as well as on the impact on the energy consumption of buildings.

With ENVI-met you can analyze the energy performance of each building in the model domain in parallel with the calculation of the outdoor microclimate conditions.

As wind and sun are the primary factors controlling the thermodynamics of a surface and the distribution of heat, the building model is directly coupled to the outdoor fluid dynamics model, providing detailed wind data for each second of the day and for each wall and façade segment of the building.
