DAYLIGHTING, PASSIVE HEATING AND COOLINGIN SOUTHSIDE ELEMENTARY: Design exercises from consecutive courses in Passive Heating and Passive Cooling

摘要

A series of design exercises investigate improving the suitability of classrooms in Southside Elementary for daylighting, passive heating and passive cooling with minimal changes to the plans, which are in Schematic Design. Quick design guidelines establish a direction and are followed by detailed calculations for passive heating and cooling. Discrepancies between the results predicted by guidelines and the detailed calculations lead to an examination of the assumptions behind the guidelines and a deeper understanding of key components of successful passive strategies. Southside Elementary is currently being designed by Dull Olsen Weekes Architects for the 4J School District in Eugene, OR. The Willamette Valley is known for its mild climate year round and for its overcast skies from late fall through early summer. The average January ambient temperature is 39°F. Summer design temperature is 89°F, but school is not in session for the hottest months of July and August. Analysis of six classrooms (three upper and three lower) show that the west upper is the (slightly) worst-case scenario for passive heating and cooling. For simplicity, the results of that room are presented as representative of all classrooms. Schematic plans show approximately 130 ft{sup}2 of glazing, half of which faces south.
