Integrated Design


Published on

Building Design has become very complex and National Building Code 2005 recommends that there should be an integrated approach for the design from the very beginning. This has to be achieved by team work, with the team consisting of the Architect, Structural and Services (Electrical, Mechanical, Air-conditioning, Plumbing, Sanitary) engineers.

  3. 3. Introduction <ul><li>Establishing a base case—for example, a performance profile showing energy use and costs for a typical facility that complies with code and other measures for the project type, location, size, etc. </li></ul><ul><li>Identifying a range of solutions—all those that appear to have potential for the specific project. </li></ul><ul><li>Evaluating the performance of individual strategies—one by one through sensitivity analysis or a process of elimination parametrics </li></ul>
  4. 4. <ul><li>Grouping strategies that are high performers into different combinations to evaluate performance. </li></ul><ul><li>Selecting strategies, refining the design, and reiterating the analysis throughout the process. </li></ul><ul><li>design teams often make incremental changes that are effective and result in high-performance buildings. </li></ul>

  8. 8. Passive solar design - challenging <ul><li>Can natural daylighting reduce the need for electric light? </li></ul><ul><li>If less electric light generates less heat, will there be a lower cooling load? </li></ul><ul><li>If the cooling load is lower, can the fans be smaller? </li></ul><ul><li>Will natural ventilation allow fans and other cooling equipment to be turned off at times ? </li></ul>
