  2. 2. What is Green building? A green building:  Operates energy efficiently  Conserves water  Comfortable, safe and healthy  Durable and maintainable with minimal environment impact Reduced operating cost Energy saving 20-30% Water saving 40-60% Reduced impact on the environment Enhanced occupant comfort, safety and health Improved productivity of occupants
  3. 3. Components of a green building
  4. 4. Technologies for Smart Green building
  5. 5. Benefits comparison
  6. 6. What is LEED? Leadership in Energy & Environmental Design Green building rating system Documentation based Evolves over time Comprehensive & National  Nationally accepted benchmark for the design & construction  The tool needed to measure impact and improve the buildings’ performance  Promotes an integrated, systems oriented approach to high- performance design and construction  Evolved since 1998 to more accurately represent emerging green building technologies  Proposals to modify the LEED standards offered and publicly reviewed by USGBC's member organizations
  7. 7. Who & What Can Be LEED? Buildings Certified Professionals Accredited LEED- History Over 10 Years in Development Available to the Public in March of 2000 Initially 1 Program (for New Construction only) Now 7 Different LEED Rating Programs
  8. 8. LEED Rating system
  9. 9. How does LEED work?  Projects earn points to satisfy green building requirements.  The number of points the project earns determines its level of LEED certification. To earn LEED certification,  A project must earn a minimum 40 points on a 110-point LEED rating system scale.  Homes must earn a minimum of 45 points on a 136-point scale. 40- 49 50- 59 60- 79 80+

  15. 15. Why LEED? LEED-certified buildings are designed to: • Lower operating costs and increase asset value • Reduce waste sent to landfills • Conserve energy and water • Be healthier and safer for occupants • Reduce harmful greenhouse gas emissions Green Buildings Can Reduce……
  16. 16. Main LEED Categories Energy & atmosphere credits promote better building energy performance through innovative strategies. Materials and resources credits encourage using sustainable building materials and reducing waste. Sustainable sites credits encourage strategies that minimize the impact on ecosystems and water resources. Indoor environmental quality credits promote better indoor air quality and access to daylight and views Innovation & Design address sustainable building expertise as well as design measures not covered under the five LEED credit categories.
  17. 17. Innovation & Design address sustainable building expertise Location & Linkages promotes walkable neighborhoods and access to efficient transportation options and open space. Sustainable sites credits encourage strategies that minimize the impact on ecosystems and water resources. Other LEED Categories Water Efficiency Energy And Atmosphere Awareness & Education provides education and tools to understand and make the most of the green building features of home. Indoor Educaional Quality Material and resources Regional priority credits address regional environmental priorities for buildings

  35. 35. GOALS AND SUCCESSES • To make the new office sophisticated and advanced green building design and technology • Set an example for their membership and the public, but also to demonstrate what is possible Increased productivity due to day lighting, good air quality, design innovation, integrated design process, waste reduction and avoidance • Greatest success - day lighting Remarkable day lighting, high-performance lighting system achieves lighting power densities among the best in the industry Indoor office environment
  36. 36. STRATEGIES •An electronic window shade system operates to maximize good daylight and minimize glare. •Walls, ceilings and workstation panels are colored white to reflect as much light as possible. •Eco-corridor features a lighter perimeter carpeting along the window line which acts as a light shelf, reflecting natural light back into the space
  37. 37. STRATEGIES •With lighting controls set to 80% maximum output, lighting power density is 54% below the ASHRAE standard. With so much daylight streaming in, use of overhead lights reduced •Biophilic strategies, those connecting staff to nature, was to provide views of the outdoors from a seated position, and 97% of all regularly occupied spaces have a direct sightline to the outdoors. •Energy use in space is monitored, including energy used for lighting, to ensure we leverage design efficiencies and systems are operating in sync. Overhead lighting
  38. 38. PROCESS • Space layout, windows, HVAC, lighting, and furniture selection and finishes •Interior as transparent as possible - low partition heights and interior glass features •Reduced the amount of air conditioning load in the summer • Innovative linear diffusers that would automatically deliver the supply air downward in the heating mode in the winter months and pivot the air horizontally while in cooling mode. This new technology significantly removes the thermal downdraft •Water wall which provides cooling and dehumidification
  39. 39. •8’ between the glass and the first workstation on the south face – eco- corridor •Daylight-responsive sensors dim light fixtures if adequate natural light is available; spaces are only illuminated if they need to be. •Occupancy sensors to control light fixtures – turns off light automatically when not in use •Thermostats used to maintain precise temperature control - regain proper temperature quickly
