We evolve and we learn. When it comes to building efficiency, we are advancing at warp speed. The Department of Energy has revealed that buildings meeting the new 2010 energy efficiency standard will conserve 18.5% more energy than structures using the previous 2007 DOE standard.  It’s like making the jump to hyperspace.

The DOE did some pretty serious study to come up with the new codes. For its findings, DOE simulated 16 representative building types in 15 U.S. climate locations. In addition, they analyzed the energy codes published by the American National Standards Institute/American Society of Heating, Refrigerating and Air-Conditioning Engineers (ASHRAE) and the Illuminating Engineering Society of North America.

The evolved 2010 standard covers a wide spectrum of the energy-related components and systems in buildings ranging from simple storage units to complex energy usage locations like hospitals and laboratories. The size of the structures also ranged from under 1,000 square feet to the largest buildings in the world.

States are expected to review Standard 90.1, Energy Standard for Buildings and update their building code to meet or exceed the energy efficiency of the new standard within two years. Certification statements by the states are due October 18, 2013.

California requires our state-developed commercial code the 2008 Building Energy Efficiency Standards, comprising Title 24, Parts 1 and 6, of the California Code of Regulations.

The DOE boasts that the newer version of the standard contains 19 positive impacts on energy efficiency. Among the modifications are new requirements for daylighting controls under skylights; increased use of heat recovery; cool roofs in hot climates; skylights and daylighting in some building types; reduced ventilation energy; supply air temperature reset for non-peak conditions; efficiency requirements for data centers; control of exterior lighting; and occupancy sensors for many specific applications.

Over a 20-year span, green buildings can $53 to $71 per square foot back on investment. LEED and Energy Star certified buildings achieve significantly higher rents, sale prices and occupancy rates as well as lower capitalization rates potentially reflecting lower investment risk…and green buildings make the world a better place.

  1. AB 1103 – California’s nonresidental building energy program implementation delayed 3 to 4 years

    Will these proposed dates in 2013 and 2014 be delayed yet again? What underlying influences are driving these delays? Perhaps the answer is found in the fledgling real estate economy and California’s projected budget shortfall of $16 Billion. Perhaps California is losing its will to go green while it flounders in a sea of red ink.

  2. Six New Partners Join the Better Buildings Challenge

    The Obama Administration announced on June 14 that six major U.S. companies are joining the Better Buildings Challenge, which encourages private sector leaders across the country to commit to reducing the energy use in their facilities by at least 20% by 2020. Starbucks Coffee Company, Staples, and the J.R. Simplot Company will upgrade more than 50 million square feet of combined commercial building space, including 15 manufacturing facilities. Financial allies Samas Capital and Greenwood Energy will make $200 million in financing available for energy efficiency upgrades through this national leadership initiative. And utility partner Pacific Gas and Electric has committed to offering expanded energy efficiency programs for its commercial customers, who are responsible for 30 million square feet of commercial building space.

    The Better Buildings Challenge is part of a comprehensive strategy to improve the competitiveness of U.S. industry and business by helping companies save money by and reducing energy waste in commercial and industrial buildings. Under the challenge, private sector CEOs, university presidents, and state and local leaders commit to taking aggressive steps to reducing energy use in their facilities and sharing data and best practices with others around the country. With the addition of today’s partners and allies, nearly 70 organizations have now joined the Better Buildings Challenge. Together, these organizations account for more than 1.7 billion square feet of building space, including more than 300 manufacturing plants, and they have committed almost $2 billion to support energy efficiency improvements nationwide

  3. To LEED or not to LEED, that is the question. The government wants your green opinion > through April 6th. The U.S. General Services Administration (GSA) is seeking public comments on a long-awaited recommendation regarding green building rating systems. Go to and share your opinion.
