building design process This process is a multidisciplinary strategy that effectively integrates all aspects of site development building design construction and operations and maintenance to minimize a building s resource consumption and environmental impact while improving the comfort health and productivity of building occupants An integrated design can also save money in energy and operating costs cut down on expensive repairs over the lifetime of the building and reduce tenant turnover Process is key to whole building design Sustainable design is most effective when applied at the earliest stages of a design This philosophy of creating a good building must be maintained throughout design and construction The early steps for a sustainable and high performance building design are Creating a vision for the project and setting design performance goals Forming a strong all inclusive project team Outlining important first steps to take in achieving a sustainable design The best way to achieve the steps above is through a high performance charrette A charrette is an intensive workshop in which various stakeholders and experts are brought together to address a particular design issue It is the mechanism that starts the communication process among the project team members building users and project management staff A facilitated discussion allows the team to brainstorm solutions to meeting the building user s requests and the sustainability vision for the building design By the time the charrette concludes the participants should have identified performance goals in the context of validating the program needs The charrette should result in good communication among project team members and the development of unified design and construction goals for everyone to work toward For sustainable building projects the project team must consider how the building design and interior function can affect the building s overall environmental impact Building design decisions address site energy consumption human comfort building material and landscaping issues A good design will integrate these factors so that the effects of one will minimally impact or even benefit the others The project team for such a design should therefore possess the expertise to analyze the interactive affects of various design strategies on the building s overall energy efficiency and environmental impact Computer simulation tools that are capable of modeling building performance are invaluable resources for understanding the trade offs associated with all design decisions Continuing to use these tools after the building is constructed give insight into how well the building is actually performing compared to how it should perform Following the design phase the project team will account for how design decisions influence construction and long term building operation Writing effective construction documents and safeguarding design goals will result in projects that are built as the original design intended In addition protecting the project site during construction will minimize the site impacts both during and after construction and ensure a safe working environment during construction ii Post construction activities guarantee continued sustainable building operation Building commissioning completed before occupation as well as continuous
