Green BuildingsGreen Buildings• Structure that has been built using process that is g penvironmentally responsible and resource‐efficient throughout a building's life‐cycle (design, construction, operation, maintenance, renovation, and demolition)
• ObjectiveObjective– Efficiently uses energy, water, and other resources– Protects occupant healthProtects occupant health– Reduces waste, pollution and environmental degradationg

AIT and UN ESCAP ProjectAIT and UN ESCAP Project• Conduct study to:
– Determine ways in which environmental design and disaster resilience can be integrated both
ti ll ( t l l ) dvertically (across government levels) and horizontally (across construction sectors) in codes that govern the planning, design and construction a go e e p a g, des g a d co s uc oof buildings in urban areas.
Vertically – national, provincial, municipalHorizontally – construction, mechanical, structural, heating,
il i fiventilation, roofing etc.
