,Objective: Discuss the logic behind building ovens and then cooling them with refrigerators.
Outcome: Students will understand how environmentally faulty design leads to entrapment of heat inside the buildings which then is drawn out by mechanical ventilation.
Prerequisites: A conceptual knowledge of processes of heat transfer and passive design.
Procedure:
Step 1: Set context in the class about the topic- Oven in Refrigerator by asking how students relate to the words Oven and Refrigerator and Oven in refrigerator.
Step 2: Ask the next question to students: What can cause heat to get trapped inside a building? State the design flaws which lead to this.
Step 2: Give a minute to students to think about the posed question.
Step 3: Students share their views on the question for 15 minutes.
Step 4: Note the points on the blackboard.
Step 5: Ask the following question to students: How was thermal comfort achieved in traditional/vernacular buildings?
Repeat steps 2,3,4.
Step 6: Ask the following question to students: Can we provide passive design solutions to this problem?
Repeat steps 2,3,4.
Step 7: Present the conclusion of the discussion.
