Green buildings are designed to reduce the overall impact of the built environment on human health and the natural environment by:• Efficiently using energy, water, and other resources• Protecting occupant health and improving employee

productivity• Reducing waste, pollution and environmental degradation

Green BuildingHistory

In the 1970s, a small group of forward-thinking architects, environmentalists, and ecologists, …began to question the advisability of building in this manner. Their efforts were given impetus by the celebration of the first Earth Day in April 1970, but it was not until the OPEC oil embargo of 1973 that the nascent “environmental movement” captured the attention of the public at large.

Green BuildingHistory

The green building field began to come together more formally in the 1990s. A few early milestones in the U.S. include:• American Institute of Architects (AIA) formed the

Committee on the Environment (1989)• Environmental Resource Guide published by AIA, funded by EPA (1992)• EPA and the U.S. Department of Energy launched the

ENERGY STAR program (1992)• First local green building program introduced in Austin, TX (1992)• U.S. Green Building Council (USGBC) founded (1993)• "Greening of the White House" initiative launched (Clinton Administration

1993)• USGBC launched their

Leadership in Energy and Environmental Design (LEED) version 1.0 pilot program (1998)

Green BuildingWhy?

Data from the U.S. Energy Information Administration shows that buildings are responsible for 48% of greenhouse gas emissions annually and 76% of all electricity generated by U.S. power plants goes to supply the Building Sector [Architecture2030]

There are many reasons to build green:• We have to (Regulatory, more strict every year)• We want to (More healthy and comfortable, feel better)• We need to (Better use of resources, saves money, reduces reliance on

energy)• We CAN!! (It’s Building Science, not Rocket Science!!)

Green BuildingDrivers

What are the primary drivers of Green Building?• Regulations

• Federal Buildings• State Buildings• Commercial Buildings• Residential Buildings

• Voluntary• Personal choice to do better• Produces better buildings – More comfortable, more durable

• Financial• Saves Money in the long term (Owner Occupiers)• Incentive programs through utilities• Green building financing? Not readily available

California EPA website

California Energy code “Title 24” (1978)Since 1978, when Building Energy Efficiency Standards, known as the

California Energy Code, were initially adopted, Californians have saved more than $56 billion in electricity and natural gas costs.

AB 32 (2006)Governor Schwarzenegger signed AB 32, the Global Warming Solutions

Act of 2006, which set the 2020 greenhouse gas emissions reduction goal into law. Executive Order S-3-05 calls for reducing greenhouse gas emission reduction for 2020 to 1990 levels; and for 2050, reduce GHG emissions to 80 percent below 1990 levels.

AB 1103 Nonresidential Building Energy Use Disclosure Program:

A building owner shall disclose the Data Verification Checklist for the building to: • A prospective buyer of the building, no later than 24 hours prior to execution

of the sales contract. • A prospective lessee of the entire building, no later than 24 hours prior to

execution of the lease. • A prospective lender financing the entire building, no later than submittal of

the loan application.

AB1103

At least 30 days before a disclosure is required by Section 1683, a building owner shall open an account or update an existing account for the same building on the EPA’s ENERGY STAR® program Portfolio Manager website, and within the account: • Provide the owner name and the owner email address; • Provide the building name, the building street address, city and ZIP code, and

the year in which the building was constructed; • Identify all sources of energy use data for the entire building, for at least the

most recent 12 months; • Provide space use characteristics as specified by Portfolio Manager for all

space types in the entire building; and • Request all utilities and energy providers serving the building to release

energy use data for the entire building from at least the most recent 12 months for specified meters or accounts to the owner’s Portfolio Manager Account; or, the owner may manually enter all energy use data for the entire building from at least the most recent 12 months to the owner’s Portfolio Manager account.

IS THIS A GAME CHANGER?Creates a value to a building’s efficiency

Would the financial industry valuate buildings differently, creating new Energy Efficient Loans?

Tenant spaces will be more or less valuable through Operating cost comparisons

Could spur Construction industry through Energy Efficiency Improvements to better position a building in the market

Some deals may come to a halt!!




AB 1103 When is this disclosure required?

• On and after July 1, 2013, for a building with total gross floor area measuring more than 50,000 square feet.

• On and after January 1, 2014, for a building with a total gross floor area

measuring more than 10,000 square feet and up to 50,000 square feet. • On and after July 1, 2014, for a building with a total gross floor area

measuring at least 5,000 square feet and up to 10,000 square feet

• Initial compliance is DELAYED until January 1, 2014

BE READY!!

Passive House

Passive House US

The Passive House concept represents today's highest energy standard with the promise of slashing the heating energy consumption of buildings by an amazing

90%. In the realm of super energy efficiency, the Passive House presents an intriguing option for new and retrofit construction; in residential, commercial,

and institutional projects.

http://www.passivehouse.us/passiveHouse/PassiveHouseInfo.html


A Passive House is a very well-insulated, virtually air-tight building that is primarily heated by passive solar gain and by internal gains from people, electrical equipment, etc. Any remaining heat demand is provided by an

extremely small source. An energy recovery ventilator provides a constant, balanced fresh air supply. The result is an impressive system that not only saves up to 90% of space heating costs, but also provides a uniquely terrific indoor air

quality.

Passive House US



Performance Characteristics

• Airtight building shell ≤ 0.6 ACH @ 50 pascal pressure, measured by blower-door test.

• Annual heat requirement ≤ 4.75 kBtu/sf/yr• Primary Energy ≤ 38.1 kBtu/sf/yr

In addition, the following are recommendations, varying with climate:• Window u-value ≤ 0.8 W/m2/K

Ventilation system with heat recovery with ≥ 75% efficiency with low electric consumption @ 0.45 Wh/m3

• Thermal Bridge Free Construction ≤ 0.01 W/mK
