Green building minimizes energy use and have positive impact on environment and makes them sustainable and preserve natural resources. Green Building Design courses helps to understand green building rating system to improve environmental performance through sustainable design and achieving a set number of parameters. LEED (USGBC), BREEAM, Green globes, Greenguard, IGBC, GRIHA etc are some of the world-wide certification programs for green building certificationsGreen building course is about conceptual understanding of different parameters affecting Design process of Green Building. It talks about World-wide Rating system for Green Building, Green Building Envelope Design, Effect of Air infiltration on Green Building, Optimized lighting for Green Building, HVAC Design for Green Building, Building Siting (Orientation), Pumping Design for Green Building, Selection of Refrigerant for Green Building, Radiant Cooling, Space heating Methods and suggestions, Energy management System and Thermal Energy Storage. This course series is useful for those who wish to understand design aspects of Green Building. The course is not about remembering points and credits but it is about conceptual understanding of different parameters affecting Design process of Green Building. Prior going for LEED or any other Green building exam, if the Design concept is understood, It will make the process of Green certification as well as credentialing process much easier. This Energy Conservation in Building/Green Building Design Part 1 includes the following topics: Benefits of the course1. World wide Rating system for Green Building2. Green Building Envelope Design3. Effect of Air infiltration on Green Building4. Optimized lighting for Green Building5. HVAC Design for Green Building6. Package and ductless AC system for Green Building
