摘要：
本研究運用數(shù)值模擬的方法研究一個新開發(fā)的濱河居住區(qū)的設(shè)計及夏季熱環(huán)境的改善。研究案例為位于日本東京附近的1個包括102棟獨立式住宅的居住區(qū)。本文應(yīng)用作者開發(fā)的室外熱環(huán)境數(shù)字模擬方法對居住區(qū)的微氣候因素的空間分布進行模擬計算。在此基礎(chǔ)上探討通過對基地表面性質(zhì)的改變以及建筑布局的調(diào)整等2種途徑來改善居住區(qū)熱環(huán)境的方法。在文中針對上述2種途徑共計5種設(shè)想的設(shè)計方案進行了模擬計算，并驗證其熱環(huán)境的改善效果。

Abstract:
The present study explains the application of a numerical simulation to investigate the thermal environment of a new riverside residential development in summer. The case study area consists of more than one hundred two-story detached houses built next to a river near Tokyo, Japan. The microclimate factors of residential district have been estimated using the CFD (Computational fluid dynamics) simulation of radiation, conduction and convection. This method leads to an improvement of outdoor thermal environment by manipulating the site design and layout planning scenarios. In total, five scenarios have been simulated for the proposed sustainable development as explained in the paper. Above simulations provided an insight into the mitigation effects of each countermeasure.
