1 Incorporating Disaster Resilience and Environmental Design in Building Codes Asst. Prof. Atch Sreshthaputra. Ph.D. Asian Institute of Technology Chulalongkorn University

2 Positive V.S. Negative Q positive impact (Functional, Health, Safety, Aesthetic, etc.) L negative impact Resource Consumption, Embodied CO2 Emission, etc. Emission of Air pollutants pollutants, Noise, Heat etc. Building & Site Soil, Water pollutants etc. Site Boundary 2

3 Green Buildings Structure that has been built using process that is environmentally responsible and resourceefficient throughout a building's life cycle (design, construction, operation, maintenance, renovation, and demolition) Objective Efficiently uses energy, water, and other resources Protects occupant health Reduces waste, pollution and environmental degradation

4 Assessment Tools of Building Environmental Performances around the World 4

5 GREEN BUILDING ASSESSMENT TOOLS LEED & Energy Star (U.S.A.) BREEAM (U.K.) CASBEE (Japan) Green Star (Australia) ESCALE (France) Green Building Tool (Canada) LOTUS (Vietnam) GOBAS (China) GBCC (Korea) HKBEAM (Hong Kong) Green Mark (Singapore) Green Index (Malaysia) TEEAM (Thailand) PCD (Thailand) TGBI (Thailand) 5

13 Issues & Solutions Some companies are using environmental friendly materials and/or environmental friendly designand construction process However not effective as it is voluntary And it lacks of verification. To make aet it effective ect ehave aeto integrate it into building codes and have to ensure high compliance rate of building codes

14 What governs the design, construction and maintenance of buildings?

15 Building Codes A set of rules and standards that specify the minimum i acceptable tbl level lof safety ft for constructed objects such as buildings and nonbuilding structures. Traditional purpose is to protect public: Health Safety For sustainable development this is not enough Has to consider Disaster resilience Environmental design

16 AIT and UN ESCAP Project Conduct study to: Determine ways in which environmental design and disaster resilience can be integrated both vertically (across government levels) l and horizontally (across construction sectors) in codes that govern the planning, pa g,design and dconstruction o of buildings in urban areas. Vertically national, provincial, municipal Horizontally construction, mechanical, structural, heating, ventilation, i roofing etc.

17 Methodology Make building codes that has integrated disaster resilience and environmental design applicable to the Asia Pacific region I ti f d i i d t ti Incentives for designing and constructing disaster resistant and environmentally friendly buildings in the Asia Pacific region

18 USA Reference Countries International Green Construction Code (March 2012) Material resource conservation and efficiency Energy conservation and efficiency Water resource conservation and efficiency Singapore Code for Environmental Sustainability of Buildings Australia Energy efficiency Water efficiency Building Code of Australia Environmental design is practiced in the country

19 Structure of Singapore s Building Regulations/Codes Red Codes Climate Induced Disaster Resilience Green Codes Environmental Sustainability

20 Sample Codes from Singapore Building Code Code for Environmental Sustainability of Buildings Construction Codes More efficient i concrete usage for building components Products with at least 30% recycled content by weight or volume (applicable only to non structural elements) Building layout design that utilizes prevailing wind conditions to achieve adequate cross ventilation Mechanical Code Use of software analysis and simulation to optimize the capacity and sizing of the air conditioning system of dwelling units to achieve energy savings.

21 Disaster Resilience and Environmental Sustainability in Singapore Code Disaster Resiliency Integrated to a small extent Within the performance requirement category Structural Design and Construction Environmental lsustainability Have been well integrated Within the performance requirement category Energy Efficiency

22 Target Countries Bangladesh Bangladesh National Building Code No emphasis on environmental design or disaster resilience India Indian Standards Not known for environmental design Philippines National Building Code of the Philippines Not known for environmental ldesign Thailand Design Code for Thailand Not known for environmental design

23 Status of the Project Project is ongoing Expected to be completed in February 2012
