Indoor climate

In large parts of the world people spend most of their time indoors. Therefore it is important that the buildings have a pleasant and healthy indoor climate.

The perception of what makes a good indoor climate can be very individual. Yet one might say that a building has a healthy and comfortable indoor climate when a combination of several parameters is sufficiently good.

Five aspects of indoor climateThe indoor climate is a very important factor for a building's functionality. When in COWI we work on creating a good indoor climate, we look primarily at daylight and lighting, temperature, draught, air quality, acoustics and noise because these aspects have the greatest influence on our wellbeing, health and productivity.

During the design process, we analyse the different aspects of the indoor environment. Different tools can help us test, for instance, the best positioning of windows, ventilation and sound barrier materials.

A good indoor climate can best be guaranteed by choosing the right design principles.

Therefore, it is important that the indoor climate is considered from the initial outline.

Improving the indoor climate
Advanced computer simulations can help improve the indoor climate in new as well as existing buildings.

The simulations are carried out already in the initial stages of the project, where we in collaboration with architects and developers evaluate and optimize the quality of the expected indoor climate.

Besides indoor climate design, we perform further indoor climate studies to identify the cause of any problems related to the indoor climate.

The most common tools
CFD - Computational Fluid Dynamics simulates temperatures, draught, humidity, radiation and solutions for ventilation and cooling.

IESVE and BSim simulate temperature, cooling - and heat requirements, ventilation requirements (natural and mechanical), passive accumulation of solar heat, the need for solar protection etc.

IESVE Radiance and Ecotect simulate daylight conditions.

BASTIAN calculates sound insulation between rooms and building facades, while Odeon calculates acoustics such as reverberation, speech intelligibility, sound distribution and clarity.
