Green Building Design Phases

1. Green Building DesignPhases

2. GBDP • Predesign • Conceptual Design • Design Development • Detailed Design & Documentation • Construction • Operations and Maintenance

3. Predesign • Understand requirements for the project and the existing site conditions/context • What to do? • Study local climate • Understand how the space is going to be used • Aligning goals • Reading applicable codes and laws • Look at prior projects for inspiration • Study existing conditions of the site

4. Predesign • Begin to understand potential and limits of passive design strategies • Opportunities for renewable energy • Explore the role of material selection • Set targets for sustainability, such as reaching net zero or certifying the building through LEED or a similar program

5. Conceptual Design • Explore alternate building and system options • Building geometry is still evolving • Take advantage of wind/sun for passive design strategies • Primary focus for energy efficiency • Daylighting and glare • Natural ventilation • Shading and solar gains • Distribution of internal loads • Envelope materials

6. Design Development • Refine the whole building design • Details of materials • Spaces • Building and mechanical systems • Work out passive design details • Better understanding of Thermal/visual comfort • Understand what active systems are needed to supplement the passive design

7. Detailed Design and Documentation • Final Design has been aligned so this is where construction/creation of the building information model • Materials and building products are specified • HVAC and lighting systems are designed

8. Construction • Design has been fully worked out by engineers/architects • Drawings are fully detailed with all construction/connections and systems designed • This phase is drive by the building contractor

9. Operations and Maintenance • Building has been built or retrofit • Prepare for occupancy • Give help with how to maintain materials/building • Test and monitor systems
