Latentwärmespeichermaterialien in transluzenten Gebäudehüllen
Project Description
The use of phase change material (PCM) to increase the energy efficiency of buildings is investigated. Research concentrates on integration of PCM within the translucent building envelope. This integrated heat storage stabilizes the temperature within the building and reduces the energy demand for heating and cooling. The transmission of light through the PCM allows increasing daylight usage and reduces the energy demand for artificial lighting. Due to the direct visual access to the PCM, its relation to the building architecture is crucial for this application.
Within the project a numerical model is developed. The model describes the physical behavior of PCM within a transparent building envelope. The effect of the use of PCM on the energy performance and thermal comfort is analyzed for different types of buildings and climatic conditions. Different scenarios for the integration of PCM within the building envelope are developed and the interaction with architecture is determined. A cost-benefit analysis is performed. The current application is also considered from the ecological point of view. Results are opposed to the analysis of competing scenarios (light weight construction, massive construction, new buildings, and refurbishment). The goal is to clarify to what extent the use PCM within the translucent building envelope makes sense from an ecological and economical point of view, and to identify the potential of this technology for the development of a more sustainable building stock.
