  4. 4 Defining Green Technology (Cont’d) Innovation: development for technology Capacity in living: creating an economic center to suit with technology and product to be proper with environment Energy: recognizing information about green technology including the fuel development, meaning of generating energy and effect of energy usage Environment: leading to search new product to reduce impact on environment

  5. 5 Major types of Green Technology Green Industry Global Change  Climate change Resource Depletion  increasingly viable technological for Renewable resources Food Supply  Agricultural methods & wastes Toxic in the Environment  design for reduced hazards

  6. 6 Green Industry is about reducing Waste Materials Hazard Risk Energy Cost

  7. 7 Green Building • To reduce impact of building to environment and human health which green building yields friendly environment by • Increasing energy and other resources efficiencies • Improving working environment to support performance both indoor and outdoor • Reducing wastes and pollution which are released to environment • Use of electrical appliances for energy conservation • Selecting construction material with friendly environment

  8. 8 Design of Green and Sustainable Building • Followed as USA’s standard of “LEED” or Leadership in Energy and Environment design which was developed by U.S. Green Building Council (USGBC Committee) • The following project checklists had to be examined: • - Sustainable Sites (SS) • - Water Efficiency (WE) • - Energy & Atmosphere (EA) • - Materials & Resources (MR) • - Indoor Environmental Quality (EQ) • - Innovation & Design Process (ID)

  9. 9 Project Checklists Indoor Environmental Quality (EQ) 17 items Innovation & Design Process (ID) 2 items Material & Resources (MR) 14 items LEED Energy & Atmosphere (EA) 9 items Sustainable Sites (SS) 15 items Water Efficiency (WE) 5 items

  10. 10 Rule of evaluating Green Building in Thailand • consisting of 6 main points as follows: • Construction site: no impact on ecosystem and encouragement for use of mass transportation • Energy Efficiency: concerning use of highly efficient energy and considering utilization of renewable energy, configuring engineering system and non-CFC refrigerant usage • Water Efficiency: considering use of water quantity which is lower than standard usage • Construction material: selecting material which is friendly environment, use of recycled and locally available material to reduce fuel consumption for transportation

  11. 11 Rule of evaluating Green Building in Thailand (Cont’d) • 5.

  20. Some Case Studies of Green Technologies 20 Many human activities cause to generate the increase of CO2 in the world carbon cycle Forest is the source to absorb and release CO2 - Economy development - Production - Industrial process - Transportation are reasons to generate CO2 Deforestation and burning forest cause to release CO2

  21. 21 Process in Industry odor Exhaust gas Water Energy (Electricity, oil) Raw material Sound Production process Product Waste water Solid waste Danger/ Risk

  22. 22 Current Problem of Energy System Human utilizes energy which leads to problem of global warming How do we reduce CO2 emission to atmosphere? Reduce or ignore the use of fuel oil having composition of Carbon (Oil, Coal and Natural gas) Reduce energy usage and increase energy efficiency Technologies are utilized to reduce CO2 emitted to atmosphere such as Renewable energy (Solar, hydro, biomass, wind etc.) Increasing energy efficiency (EE)

  23. 23 Resemblance of Green Technology (Industry) and Clean Technology That is :  Cleaner Production  Pollution Prevention  Waste Minimization
