<p align="justify">Environmental-damage is a global-major issue. The phenomenon of rising temperature, which contributes to the increase of sea level, gives impacts not only locally, but also globally. One of the main causes of environmental damages is building. Building construction and its operational activities most likely gives negative impacts to the environment. Illegal loggings, site contour change, choosing materials with big carbon foot print are the examples of non-eco-friendly construction. Inappropriate design leads to a poor quality of thermal and natural lighting. This could be solved by applying active system which consumes a lot of energy. <br /> <br /> <br /> The Mosque of Rahmatan lil 'Alamin, the object of this research, situated in an Islamic-boarding-school complex named Daarut Tauhid Eco-Islamic-Boarding School. It endeavours to realise Islamic values in term of environmental conservation. This inspires architect of this mosque to provide a mosque which is able to be a model in term of those values implementation in architecture design. <br /> <br /> <br /> Based on that awareness, this mosque is designed to minimize negative impacts of a building. Therefore, in this case, Tropical Architecture concept is chosen as the main concept. Utilising its potencies and anticipation of wet-tropical-climate characteristic is believed to be able to lower energy consumption of daily activities in this mosque. Contour conservation without changing its original contour and existing trees surrounded as well as selecting materials which are easy to obtain from around this contour, are the way to minimise bad impacts of this mosque construction. <br /> <br /> <br /> The objective of this research is to find the impact of mosque design and contour environment on thermal convenience. In this case, how to reach ideal thermal convenience is the main concern of tropical architecture. To find those impacts, a thermal-environment profile of this mosque as well as mosque-design profile is needed. There are some variables measured such as: air temperature (dbt), surface temperature (st), radiation (ground?) temperature (GT), relative humidity (RH), and lighting (E). Thermal-environmental-data recording is conducted in some period of time such as before and after jum'at prayer september 29th 2017), before and after Ashar prayer also after Isya prayer (September, 30th 2017). <br /> <br /> <br /> An analysis of the thermal environment is carried out using countor maps in order to see the thermal and daylighting distribution. The interpretation of the application of tropical architectural design in the mosque then carried out. These interpretation conclude that the performance of rahmatan lil'Alamin design provide good thermal quality. Ventilation openings, roof, void and ceiling are components of architectural design that able to maintain thermal comfort in the mosque. Another factor that contribute to maintain the mosque thermal comfort is landscape environment, which is surrounded by Eucalyptus trees. Its become shading against solar radiation and lead to reduce micro temperature. <br /> <br /> <br /> This research also provide suggestion as an improve the ability of maintain thermal comfort in the mosque. Among them is relocate skylights to the section that not have <br /> <br /> <br /> direct sunlight or using side lighting system compared to top lighting. The next suggestion is to repair the ventilation openings on the mezzanine floor to be able to provide air flow in the building.<p align="justify">
