The relation between the thermal comfort and the shape of the Built form” title_align=”separator_align_center” align=”align_center” color=”green” style=”” border_width=”” el_width=””][vc_column_text]Summary<\/p>\n The geometry of the urban fabric greatly influences the micro climate and thus affects the thermal comfort of persons in the urban environment. Urban microclimate also indirectly affects the indoor climate. Poor adaptation of urban environments can result in a greater need for active climatisation and, thus, increased energy use. This cooperation between the National Laboratory for Tests and Studies (LPEE) in Morocco and Housing Development & Management, Lund University, Sweden, dealt with the climatic design of buildings in urban environments in a warm and dry climate. There were three main parts to the project. The section Climate-conscious urban design studied the urban climate in F\u00e8s, both in a traditional, densely built neighbourhood and in a relatively new, low-density area. The maximum temperature in the traditional neighbourhood was up to 10\u00b0C lower than in the modern, both during the winter and the summer. This difference can be explained by the greater shading at street level in the traditional area due to its higher building density. In terms of outdoor comfort, the dense, traditional area is in principle comfortable during the summer, while the low-density, modern area has temperatures far outside the comfort zone. However, in the winter the modern area is more comfortable, mainly be cause of the possibility of exposure to solar radiation. The study showed that a more dense urban fabric than is practiced currently would achieve better com fort in urban areas. Simulations suggest that the ratio between the height (H) of the buildings and the width (W) of the streets should be at least 2 for positive effects in the summer. It is also necessary to allow vehicular access, so the report recommends street canyons with an H\/W-ratio ranging from 2 to 0.7. The wider avenues should be lined by trees and the buildings have arcades to shade the ground and pedestrians. The section Towards a thermal regulation made a preliminary division of Morocco into climate zones. Computer simulations of indoor climate and energy use led to recommendations for technical requirements of thermal performance, for different building elements, in the Fez climate. The main proposals are a thermal transmittance coefficient (U-value) between 1 and 1.25 W\/m2K for the roof and between 1 and 1.5 W\/m2K for the walls. South-facing walls should have about 15% glazed window area. In an actively climatised building, this would save 20\u201330% of the energy used compared to a building that is not insulated. Insulation materials are important to achieve better indoor climate and reduce the need for mechanical heating and\/or cooling. The section Proposals for thermal insulation materials concluded that wood wool slabs could be produced with local raw materials in Morocco, and slabs produced in a full-scale test were used in a building in Ouarzazate. Wood wool slabs are easy to integrate into current building methods, which means that there is little extra cost for the insulation. The estimated demand for wood wool slabs should be sufficient to establish one or more production plants.[\/vc_column_text][\/vc_column][\/vc_row]<\/p>\n","protected":false},"excerpt":{"rendered":" [vc_row full_width=”” parallax=”” parallax_image=””][vc_column width=”1\/1″][vc_column_text css_animation=””]The consultancy projects were within the framework of capacity building in developing countries.[\/vc_column_text][vc_separator color=”grey” align=”align_center” […]<\/p>\n","protected":false},"author":522,"featured_media":0,"parent":0,"menu_order":0,"comment_status":"closed","ping_status":"closed","template":"","meta":{"footnotes":""},"class_list":["post-96","page","type-page","status-publish","hentry"],"_links":{"self":[{"href":"http:\/\/qufaculty.qu.edu.qa\/djamel\/wp-json\/wp\/v2\/pages\/96","targetHints":{"allow":["GET"]}}],"collection":[{"href":"http:\/\/qufaculty.qu.edu.qa\/djamel\/wp-json\/wp\/v2\/pages"}],"about":[{"href":"http:\/\/qufaculty.qu.edu.qa\/djamel\/wp-json\/wp\/v2\/types\/page"}],"author":[{"embeddable":true,"href":"http:\/\/qufaculty.qu.edu.qa\/djamel\/wp-json\/wp\/v2\/users\/522"}],"replies":[{"embeddable":true,"href":"http:\/\/qufaculty.qu.edu.qa\/djamel\/wp-json\/wp\/v2\/comments?post=96"}],"version-history":[{"count":18,"href":"http:\/\/qufaculty.qu.edu.qa\/djamel\/wp-json\/wp\/v2\/pages\/96\/revisions"}],"predecessor-version":[{"id":139,"href":"http:\/\/qufaculty.qu.edu.qa\/djamel\/wp-json\/wp\/v2\/pages\/96\/revisions\/139"}],"wp:attachment":[{"href":"http:\/\/qufaculty.qu.edu.qa\/djamel\/wp-json\/wp\/v2\/media?parent=96"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
