Definitions
• Sustainable development meets the needs of the present without
compromising the ability of future generations to meet their needs.
• Reconciliation of society’s development goals with its environmental limits
over the long term
• Simultaneous achievement of economic prosperity, a healthy environment,
and social equity for current and future generations.

Three dimensions of sustainability
1. Environment – maintaining the earth’s life support system (e.g., ecosystem
services such as pollution filtering).
2. Social – maintaining community (civic) capacity that fosters effective
participation and ‘equitable’ treatment of all stakeholders.
3. Economic – maintaining an economic system that provides a non-declining
standard of living for this and future generations.

Natural Systems are diverse and complex…

The integrity of these systems is key to their resilience

Social systems are also diverse….

…and maintaining their integrity and diversity
is key…..

Different systems have different
requirements…

Measures for Sustainable Development
• Using appropriate Technology.
• Reduce, Recycle and Reuse Approach.
• Promoting environmental awareness
approach.
• Resource utilization as per carrying capacity.
• Improving quality of life including social,
cultural and economic.

How Are Our
Ecological Footprints
Affecting the Earth?
• As our ecological footprints
grow, we are depleting and
degrading more of the earth’s
natural capital.

Ecological Footprints: A Model
of Unsustainable Use of
Resources
• Ecological footprint: the amount of
biologically productive land and water
needed to provide the people in a region
with indefinite supply of renewable
resources, and to absorb and recycle
wastes and pollution.

Ecological Footprint Comparison
gha (global hectares) /person
Biocapacity—the amount of resources its
ecosystems can supply each year
(2.1)
Unsustainable: footprint > biocapacity

US Life Style is Unsustainable
• Between 1900 and 1989 U.S. population tripled while its
use of raw materials grew by a factor of 17.
• With less than 5 percent of world population, the U.S.
uses a third of the world’s paper, a quarter of the oil, coal
and aluminum, and 19 percent of the copper. The U.S.
ranks highest by a considerable margin in most
consumer categories as well.

US Life Style is Unsustainable
• Americans account for only five percent (5%) of the
world’s population but create half of the globe’s solid
waste.
• National Geographic’s Greendex found that American
consumers rank last of 17 countries surveyed in regard to
sustainable behavior

What do you think?
If all people on Earth had the same
consumption habits as Americans do, how
many Earths would be needed to provide what
the world’s population would consume?
a. 1 Earth
b. 2 Earths
c. 6 Earths
d. 20 Earths

Sustainable Green Buildings
23www.ProjacsaAcademy.com

Green buildings refers to a structure, the construction process
and occupancy processes that are environmentally
responsible and resource efficient throughout a building's life-
cycle from location to design, construction, operation,
maintenance, renovation, and demolition.

What will green cost?
• The most common reason for not incorporating green
elements into building designs is the increase in first cost
• Reasonable levels of sustainable design can be incorporated
into most building types at little or no additional cost.
• Sustainable materials and systems are becoming more
affordable, sustainable design elements are becoming widely
accepted in the mainstream of project design, and building
owners and tenants are beginning to demand and value those
features.
• However, advanced or innovative sustainable features can add
significantly to the cost of a project and must be valued
independently to ensure that they are cost- and/or
environmentally effective.

What will green cost?
• The cost for incorporating sustainable design elements will
depend greatly on a wide range of factors, including building
type, project location, local climate, site conditions, and the
familiarity of the project team with sustainable design.
– In most cases, these factors have a relatively small but still
noticeable impact on the overall cost of sustainability.
– Cumulatively, however, they can make quite a difference
• There can be no single answer to the question, but it is easier to
answer the question “What will green cost me on my project?”

– Reduces lighting and cooling loads
– Daylight glass and view glass are not the same
• Efficient lighting design
– Lighting Power Density < 1 W/ft2
– Pendant direct/indirect
– Occupancy sensors, auto night shut-off
• Dedicated outdoor air treatment
– Energy Recovery Ventilator or Demand-Controlled Ventilation
– Centralize exhaust zones for energy recovery

Hot/Humid Climate Energy Efficiency Strategies
• Efficient, tight envelope
– Appropriate, well-installed insulation
– Low-e, low-SHGC windows (esp. east/west facing)
– Shading for south facing windows
– Light colored roof
• High efficiency HVAC with optimized control system
– Balance with maintenance concerns
– Size properly, incorporate strategies for variable loads
• Energy star appliances and office equipment
Use energy modeling iteratively to identify and reduce loads, and
optimize efficiency of design

Successful model energy schools exist today
Homewood Middle School,
Homewood, AL
– LEED-Certified
– Low cost - $121/sq-ft
– Optimized Energy Performance
• High-Performance Windows
• Daylighting/Energy Efficient Lighting
• Efficient Heating and Air Conditioning
– Indoor Environmental Quality
• Air quality – Monitored
Temp/Humidity/Ventilation
• Daylight & Views
– 36% Energy Savings over ASHRAE 90.1-
1999

Energy efficient schools give noticeable results
Caywood Elementary School in Edgewood, KY
– Features an extensive daylighting strategy
that resulted in:
• Annual Energy Savings of $50,000
• An Energy Budget that is 50% lower than
other schools in the district

Occupancy Sensors
⚫ Shutting off indoor lights and/or
shutting off air flow when the room
is unoccupied to save energy.
⚫ Facilities management install
occupancy sensors for all the
offices and classrooms as a
general practice.

CO2 Sensors
⚫ Saves energy by reducing air intake
without scarifying air quality.
⚫ Constantly monitor air quality and if it
reaches a certain CO2 threshold then it
brings in fresh outside air.
⚫ Saves energy because its harder to
heat/cool the outside air compared to air
already in circulation.
⚫ Facilities management already installed
CO2 sensors for majority of air-handling
systems and in the highly populated areas
such as lecture halls to reduce outdoor air
intake, resulted into energy savings.

Building Information Modeling
BIM
• INTENT
• Building Information Modeling (BIM) offers a significant catalyst
that can transform the performance of the construction industry by
allowing construction professionals to develop project management
skills that simulate, in a virtual environment, the practical situations
and problems that are encountered in real-world projects. BIM is a
process involving the structured creation, sharing, use and re-use of
digital information about buildings or built assets throughout their
entire life-cycle, from design through procurement and construction
and beyond, into operation and maintenance. This involves the use
of coordinated 3D design models enriched with data which are
created and managed using a range of interoperable technologies.
Hence, applying BIM will contribute to measure and monitor the
sustainability of a building through its different phases. Table 6-2
shows the assessment factors for the Building Information
Modeling.
