The document discusses green buildings and their benefits. Green buildings are designed to reduce pollution and natural resource consumption through techniques like minimizing toxic materials and maximizing energy efficiency. They aim to be in harmony with surrounding nature, control pollution, and recycle waste on-site. Green buildings provide benefits like reduced operating costs, higher property values, and improved occupant health and productivity compared to traditional buildings.

2. GREEN BUILDINGS:
An Approach towards
Pollution Prevention

3. Concepts of GREEN BUILDING
Green Building encompasses the following:
 In harmony with the natural features surrounding
the site.
 Minimizes use of toxic and hazardous substances in
design, construction, and use of building premises.
Controls air, water and sound pollution through
efficient technology.
 Takes recourse to recycling of waste including
wastewater, waste paper, biodegradable and
nonbiodegradable
 Green architecture implies waste minimization designs and
waste recycling solutions within the building waste and
electronic waste.

4. What is a “Green Building”
“Green” Buildings are high performance
structures that also meet certain standards
for reducing natural resource consumption
“Green or sustainable building is the
practice of creating healthier and more
resource-efficient models of construction,
renovation, operation, maintenance, and
demolition

5. What is a “Green Building”?
 “Green” or “Sustainable” buildings are characterized by:
 efficient management of energy and water resources
 management of material resources and waste
 restoration and protection of environmental quality
 enhancement and protection of health and indoor environmental
quality
 reinforcement of natural systems
 analysis of the life cycle costs and benefits of materials and
methods
 integration of the design decision-making process

6.  Green Building standards include:
 Leadership in Energy and Environmental Design
(LEED)
 Green Globes
 Model Green Homebuilding Guidelines
 Built Green
 Energy Star
 Living Building

7. Why go “Green”?
 Going “Green” is the “right thing”
 Green makes business sense
 Increased flexibility to allow for longer building and TI useful life
and reuse of materials
 Improved building performance
 Increased revenue (higher rents/sales price, improved
productivity, fewer/shorter vacancies)
 Lower cost (utilities, costs of conversion)
 reduce carbon consumption,
 energy independence,
 encourage community,
 preserve natural systems

9. CONSTRUCTION
Goal: Reduce / Reuse / Recycle
Building design based on standard
sizes of materials
Buy higher quality to reduce rejects
Recycle (use scraps)
Train crew
Renovate an existing building

10. Sustainable building materials have
the following features:
• Durable and easily maintained
• Less processing required
• Low odor
• Low emitting
• Cost-effective
• Aesthetic

11. Building Design
Goal: To design the building so that it requires less
energy/water and is healthier for inhabitants when it
is complete and in use
 Air ducts for an efficient and healthy air flow
 Insulation
 Windows designed for maximum daylight
 Passive Solar Control
 Solar Cells
 Heat Exchanger for climate control system
 Location

12. Lighting
 Day lighting & Sky
lighting- Incorporated lots
of natural light to reduce the
need for electric lighting and
the associated increase in
the air conditioning load
 Energy efficient fluorescent
T5s installed in classrooms

13. Natural Ventilation
 Operable windows pull
fresh air into one side of
the classroom, while
ventilation stacks pull the
air out on the opposite
side of the classroom
 At extreme temperatures,
automatic backup
mechanical ventilation
systems used

15. Best Building Form
Solar & Energy Efficient Design
Improved Indoor Air Quality
Usage of Green Materials
Proper Mechanical Systems
Efficient Lighting
Proper Testing & Maintenance
Advanced Features of a Sustainable
Building

16. Economics of Green Buildings
 Reduction in lighting energy requirements by at least 50 percent
 Cut heating and cooling energy consumption by 60 percent
 Reduced water consumption by up to 30 percent or more
 Lower building operating expenses through reduced utility and
waste disposal costs
 Lower on-going building maintenance costs, ranging from
salaries to supplies
 Increase worker productivity by six to 16 percent
 Higher property values and potentially lower lenders’ credit risk
 Higher building net income
 New economic development opportunities

17. Benefits of Sustainable Construction
Sustainable construction makes wise use of all the
natural resources and a 50% reduction in energy use
Improves occupant health, comfort, productivity, reduces
pollution and landfill waste that are not easily quantified
A sustainable building may cost more up front, but saves
through lower operating costs over the life of the building
Building is designed as one system rather than a
collection of stand-alone systems with the help of the
integrated system approach

18. Application of Concepts of Sustainability
 Use of paints and sealers with low or no-volatile
organic compounds (VOCs)
 Reclaimed ground water to irrigate the ball fields.
 Exterior lighting directed downward to reduce night
light pollution
 Mechanically zoned science classrooms to avoid
exposure to hazardous chemicals
 Stained the concrete walls to blend with the colors of
the natural landscape
 Use of ceiling tiles produced from 75 percent post-
consumer recycled waste

19. Conclusions
 Green Building Certifications present a moving target
 Critical to work with clients early and continuously to
determine goals and objectives
 Focus on objective performance measures and clear
allocation of risks and responsibilities
 Green building issues are presented in nearly every phase
of development – look for opportunities to improve old
practices and “boiler plate”
 Don’t get bogged down, but don’t be afraid to innovate
