A Brief History of Green Building

1970’s increase in oil prices

Need for greater energy efficiency, renewables

1989 AIA formed a committee to study impact of buildings on environment

1992 AIA release “Environmental Resource Guide” funded by EPA

1992 EPA & DOE create Energy Star

1993 USGBC

1993 Greening of the White House

1998 USGBC starts LEED program

The Year is 1957…Dwight Eisenhower is elected President for the 2nd time“Leave it to Beaver “ premiers on TVAverage price of a home is $20,000 - Average annual income $4,500Price of gas $.24 – Loaf of bread $.19

Two professors from MIT design an affordable and highly flexible house

Partner with Monsanto and Disney to build their vision of what a home might look like in 1985

The House of the Future, built of plastic, opens in Disneyland…

Monsanto House of the Future

Open for 10 years – 20 million visitorsTorn down in 1967Would not go down without a fightWrecking balls literally bounced off the glass-

fiber, reinforced polyester materialTorches, jackhammers, chain saws and shovels

did not workFinally, choker cables were used to squeeze off

parts of the house bit by bit to be trucked away

During a 2014 presentation on the House of the Future

MIT Museum Architecture Curator Gary Van Zante stated,

“In the end, Monsanto found that the idea of living in a plastic house was an idea

that the public would not accept. The public did not like to be enclosed in plastic.”

Green Building &Sustainability

Most quoted definition of sustainability:

“Development that meets the needs of the present without compromising the ability of

future generations to meet their own needs."

Source: Our Common Future, 1987, Oxford University Press

EPA Definition of Green Building

Green building is the practice of creating structures and using processes that are environmentally responsible and resource-efficient

Takes into account building's life-cycle from siting to design, construction, operation, maintenance, renovation and deconstruction

Expands and complements the classical building design concerns of economy, utility, durability, and comfort

Green building is also known as a sustainable or high performance building

Source: EPA

EPA Definition of Sustainability

Sustainability is based on a simple principle

Everything that we need for our survival and well-being depends, either directly or indirectly, on our natural environment

Sustainability creates and maintains the conditions under which humans and nature can exist in productive harmony, that permit fulfilling the social, economic and other requirements of present and future generations

Sustainability is important to making sure that we have and will continue to have, �the water, materials, and

resources to protect human health and our environmentSource: EPA

Sustainability Green Building

The differences

Why is this information important?

Rising energy costsHeightened consumer awarenessResponsible building practicesMoral and economic imperativeEnhanced/emerging technologies are

less expensive and more readily available

State and federal guidelines/initiatives

Green Growth…National Association of Home Builders reports that

as of the first quarter of 2014, housing contributed $2.47 trillion to gross domestic product

Since 2005, the green share of new single family residential construction has grown dramatically— increasing from 2% in 2005 to 23% in 2013. This 23% market share equates to a $36 billion market opportunity

This information is important because

Green = Green $$$$It’s the future – hop on

board!!

Definition of Greenwashing

Disinformation disseminated by an organization so as to present an

environmentally responsible public image

It’s whitewashing, but with a green brush

Energy Star is an EPA certification program

Here’s how it works: Step 1: Builder Chooses to Partner �

with ENERGY STAR

Step 2: Builder Works with the Rater to Select Appropriate Energy–Efficient Home Features

Step 3: Builder Constructs Home and Rater Verifies Features and Performance

Step 4: Rater Qualifies the Home as ENERGY STAR and Issues an ENERGY STAR Label

HERS Home Energy Rating

System - is an evaluation of energy efficiency and forecasted energy costs within a home

Established RESNET

What is LEED? (Leadership in Energy and Environmental Design)

Delivers third-party verification that a space was designed and built using best-in-class strategies to address its entire life cycle

Commercial buildings and neighborhoods - must satisfy all LEED prerequisites and earn a minimum of 40 points on a 110 point rating scale

Homes must earn a minimum of 45 points on a 136 point scale

The 8 LEED Categories

1.Innovation and Design: 11 points 2.Location and Linkages: 10 points 3.Sustainable Sites: 22 points 4.Water Efficiency: 15 points 5.Energy and Atmosphere: 38

hurting the planet in the process

Green Products CriteriaLife cycle impacts

are lowFloor tile made of recycled

glass is green because it is made from waste material

Fluorescent bulb is green because it reduces energy consumption

emissions Save energy or water Contribute to a safe, healthy

indoor environment

Green Building Materials

Creating A Safe Indoor Environment

ELIMINATE BAD INDOOR AIR QUALITY

FIRST, eliminate material or pollution source, if not

SECOND, isolate from living space

THIRD – mechanically ventilate (exchange internal air 2-3 times)

Healthy Indoor Environment

Strategies for avoiding moisture problems

Eliminate moisture sourcesInstall quiet bathroom fans Install a kitchen range hood fanEnsure proper flashing and roofing detailsProvide roof overhangs

Paper rain screen

HEALTHY INDOOR ENVIRONMENT

Design to control radonDesign to eliminate

need for pesticide treatment

Keep garage separate from house

Design to minimize exposure to EMF

Design to Control Radon Designing and

building a house for radon control involves planning ahead so that a radon-mitigation system may be seamlessly installed should it become necessary.

Detached garage for better air quality

Attached garages must be extremely well-sealed

Choosing Products And Materials For the House

Avoid combustion appliances that are not sealed-combustion

Minimize use of wall-to-wall carpetingAvoid standard particleboardChoose zero-VOC or low-VOC paints,

finishes, caulks, and adhesivesSeal products to trap harmful chemicals
