 note = {Attic air temperature of wooden houses usually rises more than 50°C during daytime in the summer season, and this causes a temperature rise in the rooms underneath the attic space. So it is
necessary to prevent a great temperature rise in the attic space, in order to improve the room thermal environment during the summer season.
The common countermeasure for the problem is natural or forced ventilation of attic space. The authors examined the effect of the method quantitatively by the field measurements and have already
reported the results.
This time, we also discuss the effect using computer simulation. Firstly, the method of numerical analysis of attic air distribution using a k-ε turbulence model is summarized. Then, both isothermal and non-isothermal situations with forced ventilation are simulated. Not only the influences of inlet
and outlet locations and their sizes, but the cooling effect of night ventilation are examined.},
