  8. Why Integrated Design Approach

  9. Scenario in 1980

  10. Scenario in 1980 • Population • Resources • Land • Demand for new infrastructure

  11. Buildings in 1980 • Simple • Low rise • Less complicated • Less services oriented • Electrical • Plumbing • Structural • HVAC

  12. Buildings in 1980 • Electrical • Interior Lighting ->Switches • Plumbing • Floor Trap->Gully Trap->Grease trap->Manhole • Structure • Frame Structure->Column-> Beams • HVAC • Fans-> Coolers->central plant

  13. SIMPLE LIGHTING PLUMBING STRUCTURE HVAC ARCHITECT INCORPORATE & OPTIMIZE DESIGN DESIGN

  14. Scenario in 2010

  15. Scenario in 2010 • Population • Resources • Land • Demand for new infrastructure

  16. Buildings in 2010 • Complex • High rise • More services oriented • HVAC • Structural • Plumbing • Electrical • Façade; Transport; BMS; Networking

  17. Buildings in 2010 • Electrical • Interior Lighting ->Switches • Sensors -> Controls -> LEDs -> TFLs • Plumbing • Floor Trap->Gully Trap->Grease trap->Manhole • Rain water harvesting-> dual plumbing-> STP-> Irrigation systems-drip or sprinklers->recycling waste water

  18. Buildings in 2010 • Structure • Frame Structure->Column-> Beams • Post tension Slab ->Flat Slab->Structural Piles->Raft • HVAC • Fans-> Coolers->central plant • VRV system, earth air tunnel, geothermal cooling, desiccant systems, water cooled system, radiant system, chilled beam system

MONITOR PROGRESS DURING PROCUREMENT & CONSTRUCTION 7.POST CONSTRUCTION/OCCUPANCY EVALUATION

  27. SUSTAINABILITY TOOLS FOR INTEGRATED DESIGN

  28. Whole Building Design • Provides the strategies to achieve a true high-performance building: one that is cost-effective over its entire life cycle, safe, secure, accessible, flexible, aesthetic, productive, and sustainable. the type of lighting and controls used, how much natural daylight is brought in, how the space is organized, the facility's operating hours, and the local microclimate.  the ease of maintenance, global climate change, operating costs, fuel choice, aesthetics, accessibility, and security of the project A successful Whole Building Design is a solution that is greater than the sum of its parts.

  29. ENVELOPE SPECIFICATIONS ENERGY WATER WALL ROOF WINDOW LIGHTING SPECIFICATIONS CENTRAL PLANT SPECIFICATIONS STP RWH QUANTITATIVE ANALYSIS Building Sustainability Tools

  30. What is Building Performance Simulation • Complex and rigorous calculations of the energy processes within a building using computer models • Advanced software packages are capable of calculating building energy performance hour by hour for an entire year 31

  31. Why We Need Building Performance Simulation • Powerful tool to analyze how form, size, orientation and type of building systems affect overall energy performance • For optimizing: • Energy • Lighting/Day Lighting • HVAC Design/IAQ/Natural Ventilation/Airflow • Evaluating costs • Code compliance – LEED, Title 24, ECBC etc 32

  32. Common Simulation Tools DOE-2 Solar-5 ESP-r Common Simulation tools TRNSYS E-20-II & HAP TRACE 600 33

  33. Building Performance Simulation Process • Hourly Weather data • Position of sun Simulation outputs Building Description/information Simulation software - Energy consumption (kWh) - Energy demands (kW) • Indoor environmental conditions - Physical building data - Design parameters 34

  34. Examples – Building Simulation Applications 35
