Towards an improved architectural quality of building integrated solar thermal systems (BIST)
ABSTRACT Architectural integration is a major issue in the development and spreading of solar thermal technologies. Yet the architectural quality of most existing building integrated solar thermal systems (BIST) is quite poor, which often discourages potential new users. In this paper, the results of a large web survey on architectural quality, addressed to more than 170 European architects and other building professionals are presented and commented. Integration criteria and design guidelines established and confirmed through the analysis of these results are proposed. Subsequently, a novel methodology to design future solar thermal collectors systems suited to building integration is described, showing a new range of design possibilities. The methodology focuses on the essential teamwork between architects and engineers to ensure both energy efficiency and architectural integrability, while playing with the formal characteristics of the collectors (size, shape, colour, etc.). Finally a practical example of such a design process conducted within the European project SOLABS is given; the resulting collector is described, and integration simulations are presented.

ABSTRACT: The way solar systems are used in buildings is different from what it used to be. Buildings are no longer designed to use just passive solar energy systems, such as windows and sunspaces, or active solar systems, such as solar water collectors. In fact, the words passive and active no longer make sense, as the newer buildings combine several of these technologies. They may be both energy efficient, solar heated and cooled, and PV powered, i.e. they are simply “solar buildings”. The paper discusses the various approaches in building integration of solar systems, and presents a number of successful examples. It also presents some of the work being done on improving the design processes to account for the need for a holistic approach to solar building design.Solar Energy. 01/1999;

ABSTRACT: The LESO-PB has been working on the architectural integration of photovoltaic elements with the financial support of the Swiss Federal Office of Energy since 1990. In this paper, we discuss the advantages and the feasibility of the integration of photovoltaics, focusing on the following test-installations:— The DEMOSITE, an international exhibition centre of photovoltaic building elements, which was set up to inform potential users (architects, authorities and anybody who might commission a building) about the architectural integration possibilities of photovoltaics.— Two new photovoltaic systems integrated into buildings on the campus of the Swiss Federal Institute of Technology: (1) cladding on the facade of one of the buildings of the Department of Electricity, and (2) an innovative flat roof installation situated on the building of the Department of Materials where photovoltaic panels are mounted on low supports of reinforced concrete.Solar Energy Materials and Solar Cells - SOLAR ENERG MATER SOLAR CELLS. 01/1995; 36(4):381-396.
