2 DEFINITIONS Sustainability The ability of a society, ecosystem or other ongoing system to continuıe functioning into the indefinite future, without overloading or exhausting the key resources that it depends on. Source: Skripac, 2011 Sustainable Design Sustainable design seeks to reduce negative impacts on the environment, and the health and comfort of building occupants, thereby improving building performance. The basic objectives of sustainability are to reduce consumption of non-renewable resources, minimize waste, and create healthy, productive environments.

5 ARCHITECTURE 2030 Architecture 2030, a nonprofit, non-partisan and independent organization, was established in response to the climate change crisis by architect Edward Mazria in s mission is to rapidly transform the built environment from the major contributor of greenhouse gas (GHG) emissions to a central part of the solution to the climate and energy crises. Objectives: 1. dramatic reduction in global fossil fuel consumption and GHG emissions of the built environment by changing the way cities, communities, infrastructure, and buildings, are planned, designed, and constructed and; 2. the regional development of an adaptive, resilient built environment that can manage the impacts of climate change, preserve natural resources, and access lowcost, renewable energy resources. 5

19 BIM FRAMEWORK FOR SUSTAINABILITY Early in conceptual design a building s level of sustainability can be evaluated by providing its location, orientation, material, wall and window ratio, climate data etc. BIM software offer inside tools and can work third party applications for producing simulations with sustainability of a building. Simulation also illustrate the performance of a building or a space. Sun position Shadow analysis Sunshade design Acoustical design Energy analysis Solar radiation The simulation data can be used as a feedback and design in revised if necessary. Such simulation can be used in green certification systems to earm points as well. Facade design Lighting analysis View angle analysis Various simulations carried out in Autodesk Ecotech
