The information contained within this document has been developed within a specific scope, and may be updated in the future. Thermal Standard for Buildings in Lebanon :: i :: :: PREFACE This study has been developed in the context of Project “Capacity Building for the adoption and application of Thermal Standards for Buildings”. The project was funded by the Global Environment Facility, Managed by the United Nations Development Programme, and Executed under the Lebanese General Directorate of Urban Planning, Ministry of Public Works and Transport. The project falls under the Climate Change focal area and aims at the establishment of Thermal Standards for Buildings, and at enabling their adoption and application through the provision of capacity building and information dissemination. :: ACKNOWLEDGEMENTS This study is the result of a collaborative input between national efforts and international expertise. The project wishes to thank all individuals and institutions who supported and contributed to this study. Particular acknowledgements to: The General Directorate of Urban Planning The Lebanese Standards Institution The Order of Engineers and Architects, Beirut The Directorate of Meteorological Services :: FORWARD The requirements of the Thermal Standard for Buildings in Lebanon were established by taking typical representative buildings and determining the optimum building envelope improvement levels. To determine the optimum improvement levels, the incremental construction cost was balanced against the savings in heating and cooling energy costs. The proposed building envelop improvement levels were determined according to the most likely energy price scenario, cost and inflation. To be noted however, that certain building envelop parameters could not be included in this study and as such require further investigation in the future. These include the building thermal mass and the thermal bridges. This Standard is proposed to be voluntary until 2010 in order to allow a transitional period of trial and adaptation. Nonetheless, it is to be noted that the new Lebanese Building Law has already introduced incentives to encourage the improvement of the thermal performance of building envelopes.
