Thermal Comfort Case Study

21The Patels are looking for a new home in Chennai, a large city in India. Many homes there are not equipped with air conditioning, so they want to learn about which building materials provide the highest level of thermal comfort for their money. You are a project manager with Larsen and Toubro, India’s largest construction conglomerate, and it will be your job to analyze the materials and report back to the Patels.

This case study helps students achieve the following:

  • Be introduced to the concept of thermal comfort and its importance
  • Have a general understanding of how thermal comfort analysis is performed at a residential site
  • Be able to analyze the cost and benefits of many different materials and decide whether they should be used on specific problems
  • Present their findings in a short, specific, and relevant manner and defend them against other alternatives
