D. Schematic design stage

Once the clients' brief is defined and the opportunities of the site are incorporated into that brief, drafting the schematic design can begin. First, specific zones or spaces in the building should be considered, with regard to their use, any view opportunities, inside/outside connections (both visual and physical) and winter sunlight utilization.

Then ventilation strategies for summer cooling as part of the building design are established. A clear cross-flow of cooling breezes is most important in areas where summers tend to be humid.

After this, windows are located and overall size criteria for view, daylight etc. are established. Rules of thumb are used to establish approximate sizes relative to room size and extent of thermal mass as discussed later.

The schematic design is then completed and a provisional selection of construction materials made. The schematic design should be tested using simplified methods such as graphs, nomograms or user-friendly computer models.
