Ventilative cooling in Energy Renovated Residences
The objectives of this project are both to address the design challenges related to reduction of the cooling need and risk of overheating in energy renovated residences under different climatic conditions through the development of design guidelines as well as to develop attractive ventilativ cooling solutions for this building type.
In many post-occupancy studies of energy renovated residential buildings elevated temperature levels is a perceived problem by occupants. The project goal is to avoid an increased use of mechanical cooling in residences by offering an effective passive cooling solution based on utilization of the free cooling potential of outdoor air. The project deals with this through the following activities.
- Mapping of typical existing ventilation systems and technologies
- Analysis of overheating risk and cooling need for different levels of energy renovation and residence types
- Analysis of the ability of existing ventilation system to utilize the free cooling potential of outdoor air
- Development of new ventilativ cooling solutions to prevent overheating and to create thermal comfort
- Development of integrated control strategies for ventilative cooling and other passive measures
- Demonstration of the performance of ventilative cooling prototype solutions
- Development of simple guidelines for reducing the risk for overheating
In the analysis focus will be on Danish climatic conditions. However, as this is a common European problem and the market potential is European, other European climates will be included in the analysis.
