Building Energy Modeling Tool for Residential buildings Toward Zero Energy housing in Lebanese coastal region


In the last few years, the rapid development of urbanization, economic development, living standards and climate changes have dramatically increased the energy consumption in Lebanese residential building. This study aims to develop a methodology for achieving a Zero Energy Residential building in Tripoli. Tripoli is located at the northern coastal region of Lebanon, where the urban fabric and architectural patterns provide useful hints for designing an optimized prototype model. The energy consumption of the building parameters will be analyzed by using energy modeling software’s to develop the suitable variants and reach the appropriate building energy model that could be useful in the Lebanese design market. Furthermore, the study presents a review of the present energy situation, and assesses the current standard that addresses the energy efficiency in Lebanese building sector. It also offers a benchmark model that meets the requirements of the current construction law to create a real existing residential prototype model. By applying the “DCBA” or the “four variants” method, three energy model will be developed. The “D” model that represents the energy benchmark for the Lebanese residential building stock. The “C&B” model, an improved model that will be created by applying the previous Local energy efficient initiatives. In the final part, the “A” model will be created based on the Zero Energy building practices that could fit the local context. The results and outputs of this study will form a contribution to the wider design process across Lebanon and could be applied more widely on the majority of the East Mediterranean cities. This fits with the Government’s policy approach to energy efficiency development which envisages the objectives of sustainable development.
