green building strategies & project management practices for a sustainable future
DESCRIPTION
Buildings and homes (or the “built environment”) affects natural environment. Buildings, where people spend 90% of their time, adversely impact human health. Buildings also account for 40% of energy and 16% of the water used annually worldwide. Air quality inside buildings is 2 to 5 times worse than outside There are many factors to consider while studying the impacts of buildings • Land use and ecosystems where buildings are built • Materials and practices used to construct buildings • Material, chemical, energy and water resources used to maintain and operate buildings • Demolition and waste of a building at the end of its life Green Building involves minimizing these negative environmental and human health impacts and enhancing positive results throughout the building’s entire life cycle. In addition to environmental benefits, through integrated design, they can be constructed at the same or lower cost than conventional buildings. Today, buildings are responsible for more than 40% of global energy used, and as much as one third of global greenhouse gas emissions, both in developed and developing countries. In absolute terms, it is estimated that building-related GHG emissions to be around 8.6 billion metric tons CO2 eqv in 2004. What is particularly worrying is the rate of growth of emissions: between 1971 and 2004, carbon dioxide emissions, including through the use of electricity in buildings is estimated to have grown at a rate of 2.5% per year for commercial buildings and at 1.7% per year for residential buildings. Furthermore, the Buildings and Construction Sector is also responsible for significant non-CO2 GHG emissions such as halocarbons, CFCs, and HCFCs (covered under the Montreal Protocol), and hydro fluorocarbons (HFCs), due to their applications for cooling, refrigeration, and in the case of halocarbons, insulation materials. According to a survey published in 2007, one-third of population believe that global warming is the world’s most critical environmental problem, nearly double the amount of people who agreed with the same statement in 2006 Faiola and Shulman 2007.TRANSCRIPT

GREEN BUILDING
DEFINING GREEN BUILDING:
(1) Designed, constructed, and operated to boost environmental, economic, health and productivity performance
(U.S. Green Building Council 2003)
(2) The careful design, construction, operation, and reuse or removal of the built environment => energy-efficient, sustainable, high performance
(McGraw-Hill Construction 2006, Green building smart market report)
(3) (i) increasing the efficiency
(ii) reducing impacts on human health and the environment
(Cassidy 2003, White Paper on Sustainability)
GREEN BUILDING Strategies:
COST & PROFITABILITY:
A survey by McGraw Hill Construction
• 54% of Respondents
( To reduce energy cost)
• 24% of Respondents
( value to environment)
EFFECTIVE COMMUNICATION:
National Charrette Institute (NCI 2007)
• A collaborative planning process
9 Core Strategies:• Working collaboratively
• Designing cross functionally
• Design to achieve vision &
solutions
• Study the details and big picture
• Operating under constrained
schedule
• Communicating in short feed
back loops
• Including a multiday charrette
• Working on-site
• Producing a feasible plan
PHASE 1:
Feasibility Project need Assessment
Project manager Selection
Preliminary site analysis and plan
Design charrette
Final site selection
PHASE 2:
Design Initial budget and schedule
Zoning approval
Design team Selection
Construction Document development
Government permitting Review
Project bidding
Green PM Approach to Construction Vs Conventional construction
ANALYSIS & DISCUSSION:
BEGINNING WITH THE END IN MIND:
INTEGRATING THE PROJECT TEAM:
DESIGNING WITH THE WHOLE TEAM APPROACH:
USING BONUSES & REWARDS IN PROJECT CONTRACTING:
Greening project management practices can
significantly improve the ability of a sustainable
construction project to be delivered within
acceptable cost constraints.
