  • The concept embodies the entire life cycle of a building.
    Not an assemblage of “environmental” components or a piecemeal modification of an already-designed, standard building.
    These approaches not only add to the building’s cost, but also produce marginal resource savings at best.
    Considers a holistic approach.
    Capture synergies across systems through integrative design and construction
    Should be considered as early as schematic designs
    Consider Green Building Systems and Green Building
  • The issue
    Triple bottom line is also often used to refer to the concept of sustainability.
  • PEOPLE (social capital):All the costs and benefits to the people who design, construct, live in, work in, and constitute the local community and are influenced, directly or indirectly, by a project
    PROFIT (economic capital): All the economic costs and benefits of a project for all the stakeholders (not just the project owner)
    PLANET (natural capital): All the costs and benefits of a project on the natural environment, locally and globally
  • BEREEAM(Building Research Establishment’s Environmental Assessment Method) has a long track record in the United Kingdom however it is difficult to obtain current information about the system as it is not publicly available for purchase and can be purchased only through licensed assessors.
    CASBEE (Comprehensive Assessment System for Building Environmental Efficiency) Japan is a relatively new system developed for the Japanese market that is available in English. It is structured to award high assessments to superior buildings. It is simple to use and suits issues that affect Japan and Asia.
    Green Globes™ Canada and US was adapted from Green Globes Canada in 2004. This is a developing tool that addresses major renovation, tenant build-out, operations and maintenance applications.
    LEED( Leadership in Energy and Environmental Design) is currently the dominant system in the United States market and is being adapted to multiple markets worldwide
  • When reservoir water levels get lower and ground water tables drop, water supplies, human health, and the environment are put at serious risk.
  •  Gardens, landscapes, etc. that require a small amount of water
    Drip irrigation, also known as trickle irrigation or micro irrigation or localized irrigation, is an irrigation method that saves water and fertilizer by allowing water to drip slowly to the roots of plants, either onto the soil surface or directly onto the root zone, through a network of valves, pipes, tubing, and emitters. It is done through narrow tubes that deliver water directly to the base of the plant.
  • Generating electricity from fossil fuels such as diesel, natural gas and petrol, negatively affects the environment. at each step of production
    and use, beginning with extraction and transportation, followed by refining and distribution, and
    ending with consumption.
    The release of chlorofluorocarbons (CFCs) from Air Conditioning and refrigeration equipment destroys ozone molecules .
    in the stratosphere through a catalytic process and harms the planet’s natural shield for incoming
    ultraviolet radiation. CFCs in the stratosphere also absorb infrared radiation and create chlorine,
    a potent greenhouse gas. Banning the use of CFCs in refrigerants slows the depletion of the ozone
    layer and mitigates climate change.
  • The designated smoking
    areas must be clearly defined: An entire space, such as a restaurant, cannot be defined as a smoking
    area. A separate ventilation system must be installed and tested to ensure that the smoking areas
    are isolated from nonsmoking portions of the building, and a negative pressure (compared with
    surrounding spaces) must be maintained in these areas. Following the testing procedures outlined
  • According to the Whole Building Design Guide, over a 30-year period initial building costs typically account for only two percent of the total, while operations and maintenance costs equal six percent

    6. 6.  Energy Use, Global Warming and Climate Change  Resource depletion, waste and recycling  Pollution and hazardous substances in the natural and built environment. "…Our current building practices are not sustainable into the future." INTRODUCTION : IMPACT OF CONSTRUCTION AND THE BUILT ENVIROMENT
    7. 7. THE NEED FOR SUSTAINABLE BUILDING SUSTAINABLE DEVELOPMENT The United Nations World Commission on Environment and Development (WCED) in its 1987 Brundtland Report "Development that meets the needs of the present without compromising the ability of future generations to meet their own needs.” 7 WHY GO “GREEN”
    8. 8. 8 THE TRIPLE BOTTON LINE Current practices must consider the 3 "P"s  People (Social Capital)  Profit (Economic Capital)  Planet (Natural Capital) To ensure that buildings and communities create value for all stakeholders, not just a restricted few.
    9. 9. 10 GREEN BUILDINGS VERSUS NON GREEN BUILDINGS Factors Green Buildings Non Green Building Energy consumption Low High Indoor environment quality Very Good Good Emissions Low High Waste management Highly efficient Efficient Building materials Environmentally friendly Not environmentally friendly Project practices Sophisticated Normal
    10. 10. 11 KEY FINDINGS : GLOBAL TRENDS  Increased adoption of greener business practices by facility managers and real estate consultants.  Globalization is reinforcing and accelerating sustainable property developments and operating trends.  Major corporate clients are seeking greener facilities in a bid to attract and retain workers, differentiate their product , improve their image to consumers and satisfy stakeholders .  Greener business practices are being driven by increasingly prescriptive government regulations.
    11. 11. THE GREEN EVOLUTION : NIGERIA  Energy Supply ; Very low .An average of 40million litres of petrol/diesel per day is used in Nigeria for private generation of electricity.  Transportation ; Poor state of infrastructure and lack of impactful investments hence a lack of efficient transportation systems  Waste Management ; Environmentally sustainable waste disposal is still very low in most states in Nigeria with the exception of Lagos state which has a fully implemented waste management strategy.  Design and Building Innovation ; The government is yet to introduce policies and champion the implementation of green buildings in Nigeria. Private sector buy in still low.  Information: There is relatively little information about Green building technology and materials in Nigeria.
    12. 12. FACTORS INHIBITING THE DEVELOPMENT OF GREEN BUILDINGS IN NIGERIA  Lack of institutions to formulate policies and set guide lines.  Lack of information about green products and high performance building systems  Human resource and client knowledge  Low level expertise  Low level of awareness with regard to sustainability issues
    14. 14. GREEN BUILDING RATING SYSTEMS The definition of a “green” building is often in the eye of the beholder. Rating or certifying a green building helps to remove that subjectivity. Several rating systems have evolved over the years. The most popular ones include :  BEREEAM (Building research establishment’s environment Assessment Method)  CASBEE (Comprehensive assessment system for building environmental efficiency)  SBTool (Sustainable building tool)  Green Globes  LEED (Leadership in energy and environmental design)
    15. 15. GREEN BUILDINGS CERTIFICATION : LEED The LEED Green Building Rating Systems are voluntary, consensus-based, and market-driven.
    16. 16.  LEED CERTIFICATION LEVELS HOW TO PROCEED WITH GREEN BUILDINGS CERTIFICATION IN EXISTING AND NEW BUILDINGS Certification Levels Certified: 40 - 49 points Silver: 50 - 59 points Gold: 60 - 79 points Platinum: 80 points and above
    17. 17. 18  Choose an applicable category best suited for the project.  Register the project.  Assemble the project team and commence the documentation process.  Upload all necessary documentation to LEED online .  Start the application review process  Make payment for the appropriate certification review fee.   Wait for feed back from the reviewing body HOW TO PROCEED WITH GREEN BUILDINGS CERTIFICATION IN EXISTING AND NEW BUILDINGS
    19. 19. SUSTAINABLE SITES SUSTAINABLE SITES Issues The built environment has tremendous impact on natural resources and the Immediate environment. These issues relate to Hardscape, Lamdscape, exterior building management
    20. 20. SITES: SUSTAINABLE FM PARACTICES • Minimise the use of fossil fuel driven equipment for the management of building landscape. Use of battery driven/electric driven low noise equipment for cleaning pavements, mowing, lawns, clean walkways and the likes. • The use of biodegradable/low impact chemicals used for cleaning of building facades, low VOC paints. • Diversion of landscape waste from waste stream by composting to act as storm water control. • Minimizing the use of chemical fertilizers • Planting sustainable landscape
    21. 21. WATER EFFICIENCY ISSUES •Building Operations consume huge amount of water. •Dwindling water resources •There is unnecessary waste associated with water use
    22. 22. • Installation of meters to monitor the level of water consumption within the building and site • Installation of flow restrictors or reduced flow aerators on Faucets /showers. • Replacement of portable/treated water usage with captured rain water for irrigation and washing of vehicles. • Practice water efficient landscaping : Drip Irrigation, Xericulture. WATER EFFICIENCY : SUSTAINABLE FM PRACTICES
    23. 23. ENERGY AND ATMOSPHERE 24 ISSUES: Building consume a lot of energy.  Generating electricity from fossil fuels such as diesel, natural gas and petrol, negatively affects the environment.  Green buildings address the issues in two ways.  First, they reduce the amount of energy required to operate a building, and  Second, they use more benign forms of energy.  The release of chlorofluorocarbons (CFCs) from Air Conditioning and refrigeration equipment destroys ozone molecules .
    24. 24. • Conduct energy surveys and audits for building, identify areas responsible for over 10% energy consumption and put in place plan to reduce energy consumptions in those areas • Conducting systems commissioning ,retro commissioning and Ongoing commisioning (Maximum 24 Months commisioning cycle) • Right size major equipments / Plants (HVAC, Generators etc) • Exploring onsite/offsite renewable energy (Solar, Wind etc) • Building Automation Systems • Phase out the use of CFCs in Air conditioning system (Montreal Protocol phase out of CFC 2010) ENERGY AND ATMOSPHERE: SUSTAINABLE FM PRACTICES
    25. 25. INDOOR ENVIRONMENTAL QUALITY 26 ISSUES: We spend over 75% of out time indoors , and the quality of the indoor environment therefore has a significant influence on well- being, productivity and quality of life. U.S. Environmental Protection Agency (the EPA) reports indoor air pollution as a top environmental risk to public health.
    26. 26.  Maintain adequate ventilation ; Minimum 10cubic ft (0.3 cu.m) of outdoor ventilation per person . All AHU must be tested regularly to ensure standards are met.  Environmental Tobacco Smoke : Prohibit smoking in the building by instituting an ETS policy. Create designated smoking areas outside the building away from ventilation system and away from concentrations of building occupants or pedestrian traffic.  If it is not feasible to prohibit smoking indoors, design designated smoking areas that isolate and control ETS from entering other areas of the building. A separate ventilation system must be installed and tested to ensure that the smoking areasare isolated from nonsmoking portions of the building, and a negative pressure (compared with surrounding spaces) must be maintained in these areas.  Green cleaning practices: Purchase sustainable cleaning and hard floor and carpet care products . Purchase cleaning equipment meeting the sustainability criteria . Develop guidelines addressing the safe handling and storage of cleaning chemicals . Staffing and training of maintenance personnel  Implementation of integrated pest management INDOOR ENVIRONMENTAL QUALITY: SUSTAINABLE FM PRACTICES
    27. 27. MATERIALS AND RESOURCES ISSUES:  Building operations generate a large amount of waste on a daily basis  There is a need to reduce the environmental impact of materials brought into the project building and the minimization of landfill and incinerator disposal for materials taken out of the building.
    28. 28.  Sustainable purchasing : Source reduction, waste prevention, and reuse practices will help reduce consumption of virgin materials and mitigate the negative environmental impacts of materials use.  Reduced amount of mercury brought into the building through lamps : Mercury causes serious ecological and human health problems when released to the environment through human activities. Low mecury, High Output (Lumens), Longer Life  Reduce, Reuse, Recycle MATERIALS AND RESOURCES: GREEN PRACTICES
    29. 29. COST AND BENEFITS OF IMPLEMENTING THE GREEN BUILDING SYSTEMS  Direct and indirect benefits  Focusing on energy, water and indoor environmental quality long term and immediate benefits.  Energy and water efficiency  Indoor environmental quality 30
