Introduction to Green Buildings & LEED


Defining sustainability l.jpg

Defining Sustainability

  • United Nations World Commission on Environment and Development

    • “Development that meets the needs of present generations without compromising the ability of future generations to meet their own needs.”


Defining green buildings l.jpg

Defining Green Buildings

  • Design and construction practices that significantly reduce, or eliminate the negative impact of buildings on the environment and its occupants with regard to site planning; safeguarding water use and water use efficiency; promoting energy efficiency and renewable energy; conserving materials and resources; and promoting indoor environmental quality.” (US Green Building Council)


Construction impacts l.jpg

Construction Impacts

  • 76 million residential buildings in US

  • 5 million commercial buildings in US

  • consume 40 % or raw materials

  • 32% total energy produced

  • 17% fresh water

  • 25% global wood harvest

  • 5 billion gals water/day just for toilets

  • generates

    • 25-40% of municipal solid waste from C&D

    • 50% of US CFC production

    • 30% of US CO2 production


Building operations impacts l.jpg

Building Operations Impacts

  • 49% of Sulfur Dioxide emissions

  • 25% nitrous oxide emissions

  • 10% of all particulate matter

  • 1/3 of all energy consumption in US

  • 2/3 of all electricity consumption in US

  • disturbs natural habitats

  • contaminates air, soil, and water

  • depletes non-renewable resources

  • ½ of greenhouse gases

  • 35% of carbon dioxide emissions

  • community issues

  • occupant issues

    • sources: “The Architecture of Sustainability, 2002”, World Watch Institute, USGBC

Overall financial benefits8 l.jpg

Overall Financial Benefits

  • Financial Benefits of a Green Building equate to $50-$70 SF over lifetime

  • Over 10X return on any premium cost associated with building it over lifetime

Air quality l.jpg

Air Quality

  • Indoor Air Quality (IAQ) – effect the contents of the inside air has on a structure and its occupants

  • People spend 90% of their time indoors

  • Indoor air has 10-100X higher pollutants than outdoor air

    • USEPA “Indoor Air Quality” Jan, 6 2003


Energy conservation l.jpg

Energy Conservation

  • US uses 25% of world energy but only has 5% of population & 95% of our energy is from fossil fuels (US Energy Information Administration)

  • Higher Education - $2 Billion/year on energy

    (American School & University)

  • Most can reduce by up to 30% - savings can be used on:

    • New faculty

    • Upgrades/renovations for more savings

    • New programs


Water conservation l.jpg

Water Conservation

  • USA uses 340 billion gallons of fresh water per day

  • Nearly 65% is discharged into waterways

  • Energy Policy Act of 1992

  • Facilities can easily reduce use by 20-30% with little cost and effort

  • Water & Sewer Bills

  • Connection Fees & Tax Base


Occupants well being and productivity l.jpg

Occupants Well Being and Productivity

  • Relationship exists between worker comfort/productivity and building design/operation

  • Hidden sick days – higher absenteeism, respiratory ailments, allergies, asthma = lower productivity, higher insurance and medical costs

  • A 1% increase in productivity (about 5 minutes per day) equals $600-700 per employee per year - a ^1.5% equals about $1,000/yr

    • (Katz 2003 study)


Mythology about first costs l.jpg

Mythology About First Costs

  • Common Perception when we started was +20-30%

  • Past & Current Trend

  • Recent Studies

    • Average Premium <2% or $3-$5 SF

    • Most of cost associated with increased architectural and engineering design, time, modeling and integration time

    • Earlier you integrate the lower the cost

Mythology about first costs15 l.jpg

Mythology About First Costs

  • Another recent study has shown the following average increase in project construction costs, on a percentage basis for LEED certification.

    • Certified 0 – 2.5%

    • Silver 0 – 3.3%

    • Gold0.3 – 5.0%

    • Platinum4.5 – 8.5%

  • Start Early – Save Costs

    • Source: Sasaki Associates 2004


Mythology about first costs16 l.jpg

Mythology About First Costs

  • Building green can be done for no additional cost

  • Initial premium costs are entirely up to you and project specific

  • LEED buildings average only a 2-3% increase in costs, but can be done for the same budget as traditional buildings with planning

  • Savings from green building’s more than return any premium you may choose to put into it

  • Design Fees will be higher but construction costs may be reduced

  • Set Budget first then work fees within framework


General mythologies l.jpg

General Mythologies

  • Appearance of Green Buildings

    • You design it to look how you want. It can easily match traditional campus design or not.

    • Carpet, furniture and windows do not have to look different. They can look like traditional ones only they perform better and are healthier.

    • Does not need to be high tech to be green.

  • Time

    • Green Buildings take the same amount of time to construct as regular buildings. More time may be required in the Design phase though.

  • Costs

    • Green Buildings do not have to cost more. With planning they can be built at the same price or less.

    • Design fees may be higher in the beginning of the project but the extra design work will lower the actual construction costs. In the end the building costs the same and fits in the traditional budget.

      • Normal: 2 + 2 = 4

      • Green: 3 + 1 = 4

    • Long term maintenance and operations costs can be reduced by 20 – 50% with good planning.
