Development of Integrated Passive and Active Roof Modules
Abstract
A novel, integral roof in a modular design where the single roof modules fulfil different tasks and at the same time serve as outside insulation is developed by the Austrian company "Metallwerk Friedrich Deutsch GmbH". A solar thermal module, a photovoltaic module, a rooflight module and a blank module (insulation only) are developed and will soon be available on the market. For the development task, an interdisciplinary team is appointed to handle the complex thermal, structuralphysical and stress design related issues. In this paper the development of the solar thermal module with special regard to the thermal aspects is discussed. 1. Introduction The Austrian company "Metallwerk Friedrich Deutsch GmbH" had the idea to develop a novel, integral roof in a modular design where the single roof modules are employed in different applications and at the same time serve as outside insulation. The different applications are: active use of solar energy by means of solar thermal and photovoltaic modules, passive use of solar energy by means of a rooflight module and a blank module (insulation only) whereas for all modules the insulation is to meet the passive house standard. Fig. 1 shows an example how the roof can be composed out of different detigaTM modules.
