REPRESENTATION OF PERFORMANCE INDICATORS FOR THE CONCEPTUAL DESIGN OF PASSIVE SOLAR HOUSES

Ted Kesik, Luke Stern

Abstract: This paper is based on current research being conducted within the Solar Buildings Research Network. The design of advanced solar housing is a key objective of the network research activities. It has been recognized that most of the important considerations for obtaining the optimal utilization of solar energy in buildings take place at the conceptual design stage. Normally, designers attempt to optimize the passive solar efficiency of a building before integrating active systems. While rules of thumb and some heuristics for passive solar housing design are available, these are insufficient to provide useful design guidance for advanced technologies. A key functionality needed by simulation software is the representation of critical solar utilization indices while reflecting other performance attributes at the conceptual design stage. This paper examines the use of 'Processing' software to construct a visual representation interface to convey the relationship between overall building U-value, thermal mass, glazing ratio and thermal/optical characteristics, and aspect ratio of the building. The objective of the interface is to guide the user to an optimization of performance based on five key indicators: solar utilization, heating energy demand, cooling energy demand, minimum/maximum zonal temperatures, and daylight autonomy factor. The optimization reflects imposed constraints that are common to new housing design in the Canadian context.
