DTU Civil Engineering is heading an international project aimed at ensuring the right balance between energy efficiency and a good indoor climate in residential buildings. The purpose of the project is to draw up guidelines for both the construction industry and the authorities regarding building design and operation.

Humidity, particles, and a range of chemical compounds are some of the culprits when it comes to indoor climate pollution in residential buildings.

By means of ventilation, harmful substances can be removed from the building, but this often entails significant energy consumption.

Therefore, the right balance needs to be struck between energy efficiency and a good indoor climate in residential buildings. DTU Civil Engineering is now heading an international project to try and determine this balance.

Balancing energy efficiency and indoor climate

"We are aiming at preparing guidelines for both building design and building operation to ensure low energy consumption on the one hand and maintaining a healthy indoor climate on the other."

"In future, we will see a growing need to optimize energy efficiency in buildings so they come as close as possible to achieving zero-energy status. The purpose of this project is to ensure that the indoor climate does not suffer in the course of this optimization process," explains Professor Carsten Rode from DTU Civil Engineering, who heads the project.

The project mainly consists of collecting data and information about pollutants in the indoor climate. In addition, the researchers will work to identify tools and technologies which can analyse and control a building’s air quality, ventilation, and heat and humidity conditions.

Developing guidelines for construction and operation

The overall purpose of the project is to examine how the extensive knowledge already available within this area can be combined to strike the right balance between energy efficiency and indoor climate in a property.

"We are aiming at preparing guidelines for both building design and building operation to ensure low energy consumption on the one hand and maintaining a healthy indoor climate on the other. These guidelines will be made available to different industry and public sector stakeholders involved with the development of residential buildings," says Carsten Rode.

Since November 2014, preparatory work on the guidelines has been conducted under the project Indoor Air Quality Design and Control in Low Energy Residential Buildings. Now, a year on, the project will commence the three-year work phase.
