بررسي تاثير شكل سقف آتريوم بر عملكرد حرارتي و تامين نور روز در مراكز درماني با پلان گسترده

Investigating the effect of atrium roof shape on thermal performance and daylight supply in extensive medical centers

در معماري فضاهاي درماني از جمله عوامل موثر بر آسايش افراد تامين آسايش بصري، ذهني و رواني افراد است. اين مهم هرگز نميتواند تحقق يابد مگر آنكه مراجعين علاوه بر بهره گيري از معماري صحيح، ازآسايش حرارتي و بصري نيز برخوردار باشند. آتريوم ها از جمله عناصر مورد استفاده در ساختمان هاي درماني هستند كه ميتوانند براي هدايت هر چه دقيق تر نور مناسب و حرات متعادل به كار برده شوند. در اين پژوهش تلاش شده است تا با مدل سازي هاي متعدد، با نرم افزار ديزاين بيلدر و موتور آناليزگر انرژي پلاس، عملكرد حرارتي وتامين نور روز آتريوم ها در مركز درماني مورد مطالعه در تعادل قرار گيرند. است. چرا كه با وجود اهميت بالاي آتريوم در تامين نور روز، نبايد از ميزان تاثيرگذاري آن بر بار حرارتي ساختمان نيز غافل شد. عوامل بسياري بر عملكرد آتريوم ها موثر هستند كه در اين پژوهش فرم سقف، ميزان بازشو ها و ارتفاع سطح نورگير به عنوان متغير هاي پژوهش در نظر گرفته شده است، نتايج نشان مي‌دهد كه در اقليم مورد بررسي، شهر تهران، آتريوم با فرم سقف شيرواني با درصد بازشوهاي معين در هر جهت جغرافيايي عملكردي مناسب تر از ديگر گزينه هاي مورد بررسي دارد.

Nowadays there is more attention to the therapeutic process and medical activities in designing of health centers. The interaction between therapeutic spaces and the environment and also the environment and the process of treatment is eliminated. This project is done to evaluate the environmental effects of medical places and the beneficiary of these effects by considering to be sympathize with the environment as a subset of sustainable architecture. This medical center is specifically for the patients that are physically handicapped. According to their necessities this building has an extensive plan, and also using methods of lightin like atrium skylight is required. The building is located on a site with therapeutic usage in district 22th of Tehran Municipality that has a suitable access to the main transport arteries as well as the aesthetics fit into the surrounding landscape. At the beginning of this research, the location was scanned by the method of EIA, And the zones that were an appropriate response to the weighted criteria have been determined through questionnaires and AHP, Then one of these areas were selected based on the project necessities. 8 Alternative was designed in it with an area of 9 thousand square meters, then it was evaluated In terms of heating and cooling load by “design builder” software. After selecting the optimal alternative the initial plan was designed. according to the studies and the daylight analysis some atriums was considered, then 8 Alternative was designed and studied to determine the exact proportions of the atrium, shape of ceiling , dimensions and location of the openings. Finally, the optimal alternative has been selected and the process of completing the final design was done. In this alternative, the optimum height of the atrium from the roof is half of the height of the atrium in this building. Shape of the roof is flat with rectangle base and the with optimize opening.
