Item 3D visualization of a timber frame historic building : Partite usage and its impact on the structural system(International Society for Photogrammetry and Remote Sensing, 2017) Gunay, SerkanThroughout their lifetime, historic buildings might be altered for different kind of usage for different purposes. If this new function or new usage requires utilization of the building in separate units, this separation might affect the historic building's functionality and structure and as a result its overall condition. Yorguc Pasa Mansion conservation project was prepared as a part of the Middle East Technical University (METU) Master's Program in Documentation and Conservation of Historic Monuments and Sites for the historic Yorguc Pasa Mansion. The mansion is a 19th century Ottoman Period timber frame building in Amasya, a Black Sea Region city in Turkey that has traces from different civilizations such as Hittites, Greeks, Romans and Ottomans. This paper aims to discuss the affects of the partite usage on structural conditions of timber frame buildings with the case study of Amasya Yorguc Pasa Mansion through the 3D visualized structural systems. © Authors 2017.

LEED is an evaluation system that rates how sensitive buildings are to the environment and the objective of LEED is to reduce emissions through development of highly efficient mechanical systems, designing of durable and efficient wall systems and by providing additional thickness to insulation. Unfortunately currently there are many cases where these wall systems and insulations are supported by thin steel studs, which are highly conductive of energy and are 400 times more conductive than wood. The aim of this paper is to investigate the use of thermal bridging in a LEED certified building. Thermal bridging is a major source of heat loss through studs and wall systems in many buildings worldwide. The investigated building is Gold certified building built in 2011 located in Toronto, Canada. The exterior walls consist of a copper and brick cladding and steel studs. Using thermal imaging, as a non-destructive testing method, this research investigates and identifies the location of thermal bridging. This study recommends how to integrate infrared imaging into the LEED certification process and how to improve the future design of efficient wall systems. © 2015 The Authors. Published by Elsevier Ltd.Item The importance of integrating LCA into the LEED rating system(Elsevier Ltd, 2016) Dekkiche, Hamoud; Taileb, AliLEED (Leadership in Energy and Environmental Design) is a rating system that rates green buildings; LCA (Life Cycle Assessment) is a tool to evaluate the environmental impacts of building materials. The aim of this paper is to demonstrate the importance of integrating LCA into LEED to enhance its rating system. The LEED Gold building presented in this research is the Centennial College Progress Campus located in Toronto, Canada. Using ATHENA® Impact Estimator version 4.5 to conduct the LCA, this study analyses how different building envelope solutions and building materials affect the results of the environmental assessment of a whole building over the building's life cycle of 60, 80 and 120 years. Environmental impact assessment of LEED buildings is discussed, further research topics are suggested; for example how to develop specific LCA software tools and integrate them into LCA analysis for green building rating system. © 2016 The Authors.
