Today, renewable resources and the crucial role of passive strategies in energy efficiency in the building sector toward the sustainable development goals are more indispensable than ever. Natural ventilation has traditionally been considered as one of the most fundamental techniques to decrease energy usage by building dwellers and designers. The main purpose of the present study is to enhance the natural ventilation rates in an existing six-story residential building situated in the humid climate of Rasht during the summertime. On this basis, two types of ventilation systems, the Double-Skin Facade Twin Face System (DSF-TFS) and Single-Sided Wind Tower (SSWT), were simulated through DesignBuilder version 4.5. Then, two types of additional ventilation systems were proposed in order to accelerate the airflow, including four-sided as well as multi-opening wind towers. The wind foldable directions were at about 45 degrees (northwest to southeast). The simulation results show that SSWT could have a better performance than the aforementioned systems by about 38%. Therefore, the multi-opening system was able to enhance the ventilation rate by approximately 10% during the summertime.

The paper presents a comparative study of the climate responsive design strategies and indoor thermal performance of three vernacular houses in Guanshan Township of eastern Taiwan by building survey and instrument measurements. These houses are all about 80 years old. They are of Chinese style, Japanese style, and a mixture of both styles. All three houses are popular building types in the region. Key findings include: (1) Space buffer, thermal insulation, ground exposure, and natural ventilation are the key elements of climate responsive design strategies. (2) The climate responsive design strategies of the three buildings, while using similar building material, are not the same. They are strongly associated with the buildings’ cultural roots as well as the buildings’ use patterns. (3) The Chinese-style house is a heat rejecter. It is comfortable in spring and summer. The mixed-style house is a heat keeper. It is comfortable in winter and spring. The Japanese-style house is well-ventilated and has equal thermal comfort level at around 50% in all seasons. It is uncommon that vernacular buildings from different cultural traditions coexist in the same region. This study provides detail appraisals of their respective sustainable design strategies in hot and humid climate.
