Integrated Solution - Double Skin Facade and Diffuse Ceiling Ventilation for School Renovation

The project aims to develop and demonstrate an integrated solution "I-DIFFER" by combining Double-Skin Facade (DSF) and Diffuse Ceiling Ventilation (DCV) technologies. Further including integrated shad-ing de-vice and intelligent control to improve the overall indoor environment (air quality, thermal, acoustic, and visual comfort) and building energy performance. The solution is suitable for a renovation project, which triggers an upgrade of the building’s HVAC systems due to deterioration of the indoor air quality, especially for institutions, schools, and offices with high internal loads and ventilation demand. The solu-tion has the benefit of minimum interference with the building interior during the installation and it allows to build-up on already existing acoustic solutions and HVAC systems in the building. The solution is tar-geting buildings with significant needs for improvement of the overall indoor environment and the build-ing envelope in Nordic and other European markets with mild winter conditions.

The project has been supported by the Energy Technology Development and Demonstration Program (EUDP) under the name I-DIFFER (Journal number: 64020-2140). The project is being carried out in cooperation between Aalborg University, COWI, Troldtekt and Aarhus Municipality.
