Lecture One:

Sustainable Design

Introductory issues for design professionals

The fuel, food and financial crises are alarm bells warning of theun-sustainability of global consumption. A new mindset is needed.Opportunities to reduce energy use and carbon emissions,especially through technology improvements and behaviouralchanges, and to promote alternative energies can be acceleratedas people gain awareness of their ecological footprint. This classwill explore and promote the expansion of the clean energy intechnology sectors and sustainable facility design.

Class Content Lectures 1-3 Reading assignments at each class:

Glossary of terms use by this industry knowing and using these termswill prove to others that you are familiar with the notion of Sustainability.

Professional articles on line and on paper on green topics

Case studies: Examples of various buildings types that proved sustainability is possible,

saves energy, cost and improve the quality of life for users and visitors alike: Corporate headquarter, Bank building, Low income housing, Elementary school, Office building.

Final Testing : Multiple choice questions regarding data presented in lectures and in the

reading assignments.

Or one page description on topics related to case studies such as: Analyzing a building of your choice in terms of sustainability and write in few words

the category in which the bui lding meets the sustainability standards and howcould increase the sustainability level.

LECTURE 1 44

History and background US Green Building Council

over15 years of developing the framework for green building design, construction operation.

LEED is an internationally recogni zed green building certificationsystem, providing: verification that a building or community was designed and built using

strategies aimed at improving performance across all the metrics that mattermost: energy savings, water efficiency, CO2 emissions reduction, improved indoor environmental quality stewardship of resources and sensitivity to their impacts.

LEED (Leadership in Energy and Environmental Design) Is world renown with over 100,000 LEED Professionals Globally in 50 US

states and more than 41 countries. The number of projects that requireLEED accredited professionals involved in building projects is growing.

So Many Standards WHICH ONE TO FOLOW?

International green Construction Code ( IgCC ) issued in 2012 once endorsed bystates government, will become the single International Code for compliance withminimum Green Design Standards.

History and background

LECTURE 1 10

Sustainable theories are not new .

Were known and applied since 15th century atlocations around the globe : Villages in Himalayan mountains

Gothic Cathedrals

Peasant farmhouses great examples are in Romania

Industrial buildings of the 19th century

Hi-tech LEED certified buildings of today

Their common goal : provide shelter and security for the basic physical

functions of life and at times also for commercial, industrial

and agriculture activity [Encyclopedia Britannica].

LECTURE 1 14

Green building sector grows fast, and more andmore: Buildings professionals, owners, and operators are seeing the benefits of green

building. Job growth in green design area is expected to

increase nearly four times the job growth for allother occupations combined.

A number of international initiatives, includingbillions in new investments in: renewable energy, energy efficiency, and energy research are likely to accelerate the

job growth. Many of these positions will be in the energy

sector; however facility engineering will see itsshare of green jobs growth.

Getting those jobs without some kind of industry-specific academic or business experience can be

difficult. Few schools offer specialized programs, but a

better choice might be enrolling in a few courses inan engineering school, or find an industry-specificclass.

If nothing else, you will demonstrate an interest inthe green industry.

LECTURE 1 1818

Why Sustainability ? Why is Sustainability important now and how building design

can help the environment?

Buildings are the single largest contributor to global warming,

accounting for almost half of the total annual US energy consumption

and CO2 emission.

40% of primary energy use. Primary energy is : Solar energy ,Wind

power Fossil fuels Hydro power, Nuclear fuels, Geothermal power

72% electricity consumption

39% CO2 emissions carbon dioxide

13.6% potable water consumption

40% of the raw material used

30% of the waste output

Data by US Energy Information Administration

Conditions above are assumed to be true if not worst in most

countries today.

LECTURE 1 1919

Why Sustainability ?

CO2 emission = greenhouse gas = climate change

LECTURE 1 2020


What Green Building Addresses: Climate change

Resource depletion

Water consumption

Degradation of ecosystem / habitat

Indoor environmental quality

Occupant comfort and productivity

LECTURE 1 2121


What Green Bui lding can do: Reduce overall energy use in buildings by 24%-50%

Reduce CO2 emissions caused by buildings by 33%-

39%

Reduce water use in buildings by 40%

Reduce solid waste generated in buildings by 70%

The architect should know how to achieve the

above sustainability goals.

LECTURE 1 2222


What Green Building brings: Economic prosperity

Social responsibility

Environmental leadership

The architect should be part of the sustainable

team and should know what is his / her

contribution to achieve the sustainability goals ofthe Client.

How can a design professional address

green building? Is this a new and different type of building?

Or

Is this an added new design set of standards to existing

ones?

It is both.

Cost Implications:

LECTURE 1 2626

Cost Implications:The 2006 study shows there is no significant

difference in average cost for green buildings as

compared to non-green buildings The cost of Green Revisited, David Langdon 2007

Historical data shows that:

Traditionally vernacular sustainable buildings are low cost.

The low cost design is always best design.

Good design is good business for bottom line.

New accounting methods is needed:

ROI Return on investment = payback time

Life cost analysis = the cost of an item from inception to

the end of its life

LECTURE 1 27

Cost Implications:

Life Cycle Cost Analysis :

Identify cost per each sustainable design category as initialinvestment vs. long term savings and payback periods.

The Life Cycle Cost is of importance in facilities designbecause:

the initial cost of the building can be easily controlled during thedesign process,

the entire cost of a facility is now being considered on longer andfull life parameters called Life Cycle Cost Analysis.

These parameters are:

original product cost,

installation cost,

maintenance cost,

demolition costs,

disposal costs.

LECTURE 1 2929

Cost Implications:

In Reality it is a new market shif t: Green buildings attract business at a higher rental

rate and selling price due to:

Lower operating cost,

Good image in the community,

Higher productivity

Healthier for occupants and visitors

By design, the architect must focus on how to

bring success to a Clients bottom line followingsustainability standards.
