Good Morning,

What is the most difficult climate region to design for without the use of a mechanical system?

thank you.

  From my studying, I would say hot/humid. There is a good review of climates in Heating, Cooling, and lighting. Also, I strongly recommend the Site Planning and Design Handbook- especially chapters 2, 3, and 4. Good luck!

  I agree with Kylie. Buildings in other climates can use a variety of passive ventilation, heating and cooling techniques to offset mechanical systems usage. In hot-humid climate, buildings heavily rely on AC mechanical systems to reduce humidity that brings fungi, mold and discomfort to residents. Elongated building form and cross and stack ventilation would help in a hot-humid climate, but one cannot leave a day inside an apartment without AC.

  According to Michael from Amber Book cold climates is the worse one.

  We did fine for millennia without air conditioning...but we couldn’t live in cold climates until humans discovered fire.

  I would also say hot humid based on all my study materials. In cold climates, you can always have a fireplace to keep the space comfortable, while in hot humid climates, no matter how well the space ventilated, as long as the air moisture is high, it still can't reach the comfort zone. The only way to reduce air moisture content is to use dehumidifier. The key word of the question is mechanical system. A fireplace is not mechanical system.
