Integrating Building Information Modeling (BIM) and Energy Analysis Tools with Green Building Certification System to Conceptually Design Sustainable Buildings

摘要

It is commonly known that the energy consumption of buildings is quite high; therefore, owners, architects, and engineers should be more concerned about the sustainability and energy performance of proposed building projects. For years, energy analysis tools have been used by designers to design energy- efficient buildings. Generally, the energy analysis for this type of facilities is mostly conducted at the end of the design stage, once their components and elements have already been selected. However, analyzing the energy consumption of those components at the conceptual design stage is very helpful for designers when making decisions related to the selection of the most suitable design alternative that will lead to an energy-efficient building. Building Information Modeling (BIM) has the capability to help users assess different design alternatives and select vital energy strategies and systems at the conceptual design stage of proposed projects. Furthermore, by using BIM tools, designers are able to select the right type of materials early during the design stage and to make energy-related decisions that have great impact on the whole building life cycle.The main objective of this paper is to propose an integrated methodology that links BIM and energy analysis tools with green building certification systems. This methodology will be applied at the early design stage of a project?s life. It will help designers measure and identify potential loss or gain of energy for different design alternatives and calculate the potential LEED points they may accumulate and gain and accordingly select the best one. An actual building project will be used to illustrate the workability and capability of the proposed methodology.
