Hi everyone;
I am involved with a new project at the University of Hawaii-Hilo. The climate is hot and it rains over 10'/year. I am looking for successfull examples of naturally ventilated campus buildings in this type of climate. Rain, mold and corrosion are huge problems.

You might look at examples of traditional buildings on Pacific islands, such as the men's houses of Yap. I have been inside one of these on a hot day, and it was considerably cooler than sitting under a tarp canopy. The seating area is on a raised platform, with open sides, so that there is a gentle breeze. The roof is tall and the eaves extend out a couple feet from the inside seating area, to protect from rain and sun. I think that having the windows and seating area raised a couple of feet off the ground were key to ensuring that there would be a constant breeze. I'm interested to see your end product!

I appreciate your insight Meg. I'll take a look. Interesting issue in Hilo is the "vog", or volcanic fog coming from the mountains. Makes ventilation problematic. Haven't yet gotten into that part of it. Will check out the Yap.

Aloha Ron,

Here in Portland, OR we deal with humidity, heavy rainfall and mold issues regularly. Not quite the same temperatures as Hawaii though.
Here are some links to examples of projects that may be of use in informing the UH Hilo project (some of them including our Newberg project use passive ventilation:

Alex;
thanks. I am actually from Portland and have love the city. The big difference in Hilo is that it is like a huge sauna. 80's every day with rain. I'll take a look at your information though. I appreciate your response.
