Vision
•
Through leadership collaboration, the global construction industry will transform traditional
building practices and fully adopt sustainability as the means by which our environments thrive,
economies prosper and societies grow to ensure the future health of our planet.
Mission
•
Ensure Green Building Councils are successful and have the tools necessary to advance.
•
Stand as the premier international voice for green building design & development.
•
Foster effective communications and collaboration between Councils, countries, and industry
leaders.
•
Support effective green building rating systems.
•
Share best practices globally.
Goal
•
Buildings and Communities will enhance the health and vitality of life within a generation.
How do buildings respond to the principles
of sustainability?
The design of our buildings is a key contributor to the
quality and sustainability of our built environment.
The factors that relate to the design of our buildings are
varied and wide-ranging, and include:
Site and Neighborhood
The goal is to reduce the impact of the building on its surroundings and the
surroundings on the building.
By improving the separation and interconnectivity between buildings; considering the
way in which the use of the site/layout influences microclimate, wind velocities and
temperatures around the building (heat island effect); provision of neighborhood
amenities, public services and recreational facilities; respect for cultural heritage;
overshadowing and view protection; opportunities for site greening; enhancement of
ecology and biodiversity; landscaping; and air, water, noise and light pollution.
Materials and Waste
The use of "green materials" is becoming increasingly important, as is the
enhancement of systems to maximize waste reduction and recycling. This is
important across the full life cycle of buildings and starts with good design, and
then use of innovative construction practices. Flexible design should be used to
reduce internal demolition and rebuilding over the building's lifetime. Increased
emphasis is being placed on the use of recycled, non-harmful, low energy,
reusable and recyclable building materials. Another important design factor is the
provision of space and facilities for "at source" waste separation and recycling by
building occupants.
Water Conservation
Water consumption and waste is heavily dependent on the design of our buildings.
Inclusion of water saving devices (faucets, showers, toilets, etc), recycling / reuse
of grey-water (from bathing and washing) and rainwater, and water metering and
leak detection, can all help to optimize the use of water, which is an increasingly
scarce resource. Site drainage, effluent management, low-maintenance native
plants, and efficient irrigation systems can further reduce the water footprint of a
building.
Energy and Climate
The increasingly accepted goal is to create buildings, which are energy efficient and low
carbon in nature. Key design considerations include the building shape and orientation;
size and type of glazing; wall and roof insulation; shading; natural ventilation; daylighting and permeability, to ultimately create "passive low energy" buildings. At a
service level, the aim is to achieve energy efficiency of air-conditioning, ventilation,
lighting, lift, escalator, water heating and other building systems, and to maintain
effective controls and metering provisions to help users monitor and control their energy
consumption. Increasing emphasis is also being placed on the incorporation of on-site
renewable energy (solar heating, photo-voltaic panels, wind, etc) and ultimately to
consider the "embodied energy", i.e. the energy used in the manufacture, transportation
and installation of building materials.
Indoor Environment
The goal is always to create a safe, healthy and comfortable home or workplace for the
occupants.
Key design considerations include: thermal comfort, indoor temperature, humidity and
air movement, natural ventilation, day-lighting and views, indoor air quality, avoidance
or removal of outdoor and indoor pollutants, health and hygiene in plumbing, drainage
and refuse collection systems, indoor noise, acoustics and vibration, accessibility for the
young, aged and people with disabilities, and amenities for building users and public.
Cost benefits
The most obvious benefit to an occupier of a sustainable building is that of reduced utility costs
(both energy and water). In an era of increasing oil prices this benefit can be expected to
increase.
The less obvious, but more important benefit is that studies are beginning to show that ‘green
buildings’ offer improved health and well being of the staff, resulting in reduced sick days and
increased productivity.
The benefits are typically expressed in percentage improvements, however, if one reviews these
in terms of €’s saved by the occupier in a year, then the true financial benefit can be reviewed.
On a typical office building with staff on an average Western European consultancy practice
wage the financial savings of occupying a green building could be in the region of €900 per m2
per year.

What are the Costs?
MYTH:
Green Buildings are more expensive to build!
FACT:
Correctly managing the sustainability requirements on a project can bring down the capital costs.
FACT:
On a well-managed commercial project with early input on sustainability, project costs aimed at
achieving a sustainability accreditation rating (BREEAM/LEED) can be reduced from more than
10-12% down to 3-5%.
FACT:
In the future, market values are going to be significantly affected by the sustainability rating.
Evidence has started to suggest an increased rental values of 3-8% and higher sales values of
5-10% for internationally accredited (BREEAM/LEED) sustainable buildings.
Other Considerations
The cost of getting a building BREEAM/LEED certified should be considered a
marketing cost and not a construction cost because the certification raises
awareness about a building, leading to publicity and tenants who move in because
the building is “green”. Studies have shown that owners and developers who choose
not to have green buildings or ignore certification will find that potential tenants aren’t
interested in their buildings in a matter of a few years. 14.83%.
In a 2009 report entitled "Who Pays for Green? Economics of Sustainable Buildings,"
CB Richard Ellis Group found that basic "green" certification levels in the UK add
about two to three percent to the overall construction costs, while higher levels of
accreditation add between five to seven percent. And while both the CB survey and a
recent CoStar report showed higher rental, sales and growth rates among LEED
certified buildings in the U.S, the former showed the gains to be more or less on par
with the extra costs.
Further, the CB Richard Ellis report also found that energy savings could be anywhere
from 10 to 50 percent and up - a huge margin that might be too often overlooked.

Where do investments have more value?
The value case for sustainable building is compelling:
For owner occupiers, a 20-year whole-of-life cost view indicates the marginal cost increase of
sustainable building is likely to be repaid between five or six times by operating cost savings
alone.
For tenants, the probable 20-year rental premium for sustainable buildings is likely to be repaid
by a factor of approximately three from operating cost savings only.
For owner occupiers, developers and investment funders, a residual land value analysis shows a
sustainable office building may have a land value of 40% more than that of a conventional
building. Its true worth is nearly 40% more than a conventional building.
The case studies show that to achieve the above investment returns, the difference in the initial
capital cost of sustainable buildings compared to conventional good quality buildings varies from
15% less to 11.5% more, with sustainable features initially costing an average of 2-6% more.
Sustainable buildings are intrinsically more economic to run over their whole lifetime. They
reduce waste and are much more efficient in their use of key resources such as land, energy,
water and materials. They can also be healthier and more comfortable, and support greater
productivity, with improved levels of natural light, cleaner air and a higher degree of personal
control. They are also adaptable and durable enough to meet the requirements for flexibility and
needs of future generations of building occupiers.

How do we measure a Green Building?
There are basically 6 criteria to consider:
• energy efficiency
• indoor environmental quality
• sustainable site planning and management
• materials and resources
• water efficiency
• innovation
