High School Building Case Study: Samuel Brighouse Elementary School

Satisfactory Essays

Taking these criteria into consideration,a systematic search through various schools and after holding the potential case study buildings with the selection criteria, eight buildings were found to match them sufficiently asmentioned in Table 1 below. For the whole description of each building see Appendix A.

Maximum temperature ranges are between 45 and 75 degrees Fahrenheit.[11]
Ventilation strategy: courtyards, Low-perimeter louvers, and clerestories in sloped roof
Strategy mechanism: The concept of thermal buoyancy and pressure differentials cause because of the two courtyards, as part of air flow moving up and part of it down, to form a large vortex leading to a very high-pressure build-up surrounding the building. This concept emphasis is drawing fresh air through low-level perimeter windows and louvers located behind the heating units and venting it through high-level clerestories in thesloped roof which act like thermal chimneys (see figure 6).[11]
In 80% of the building, Carbon dioxide sensors and occupancy sensors automatically adjust louvers to control ventilation and conserve energy. In heating mode, the air passes over fin-tube water heating elements located at the perimeter louvers before it is introduced into the classroom
