Investment in Building Energy Efficiency

For investors interested in energy efficiency in either conventional or green construction, meaningful answers to a few questions will go a long way towards ensuring a sustainable investment.

To determine how a building's energy use compares to other similar buildings in the country, the U.S. EPA's ENERGY STAR program developed an energy performance rating system that rates a building's energy efficiency on a scale of 1–100. A building that scores in a 75 or above on this scale (placing its energy performance among the top 25 percent among similar buildings) can earn an ENERGY STAR label. Receiving a rating for a building is easy and can be done at the energystar.gov Web site using Portfolio Manager, a free, online tracking and benchmarking tool.

More than 62,000 have been rated, and more than 4,000 of them have earned the ENERGY STAR label to date.

New Construction Project Energy Efficiency

Has an energy target been established?

New construction project teams often promote building designs that are energy efficient, but do not always provide an estimate of the completed and commissioned building's expected energy to owners and investors. Many green building rating systems and programs targeting energy efficiency in building design rely on computer modeling primarily concerned with estimating if a design exceeds the building code, which is not an indicator of how much energy the building will use.

Establishing energy targets can help drive energy-efficient design choices; energy efficiency goals should be set based on comparisons to actual building energy use. EPA's Target Finder tool provides an easy way to develop an energy use target tailored to a specific design project.

Investors should ask about a new building design's estimated energy use and if it is Designed to Earn the ENERGY STAR.

Green Certified Buildings

What method or system was used to certify the building? Did it earn points for energy efficiency?

If a building has been operating for at least one year, it should be benchmarked for energy efficiency using the ENERGY STAR Portfolio Manager tool and against its energy target.


The building envelope, mechanical systems, lighting, and controls systems

Energy-efficient buildings have efficient components and systems that are properly designed and sized and are actively managed once occupied. It is important to make sure that these investments are not subverted in the name of green design or value engineering.

The Commissioning Strategy

Specifying and installing the latest energy saving technologies may make little impact unless these technologies are properly commissioned along with other building systems. New technologies often require more attention during commissioning. Be sure that the project budget includes proper funding for commissioning.

The U.S. Environmental Protection Agency and the U.S. Department of Housing and Urban Development recently awarded an Irvine, Calif. non-profit developer an Energy Star award for its contribution to reducing greenhouse gas emissions through energy efficiency.

Jamboree Housing Corporation received the Energy Star’s Excellence in Affordable Housing award for its efforts from 2003 to present to incorporate energy-efficient appliances or practices at its developments for workforce families and lower-income seniors that began with 348 apartment units, to 154 currently under construction, and 746 under renovation.

“The EPA applauds Jamboree Housing for its leadership in energy efficiency by bringing EnergyStar products to the population it serves,” said Deborah Jordan, the EPA’s Air Division director for the Pacific Southwest. “EnergyStar products save energy, which reduce greenhouse gas emissions, prevent pollution and lower energy bills.”

Jamboree serves families and seniors with a household income between 30-80 percent of the area median income, with an emphasis in the 50-60 percent range. The median household income for residents living in Jamboree communities is $19,000.

The EPA awarded 12 Excellence in Affordable Housing awards nationwide that include two national winners. The award recognizes governments, non-profits, non-governmental organizations or utilities that have made exceptional or market-leading contributions toward advancing energy efficiency in affordable housing through the use of Energy Star-qualified products and appliances or Energy Star’s residential construction guidelines.

The national winners were two of seventy-nine annual Energy Star award winners. The award categories included Sustained Excellence, Partner of the Year, Energy Star Award for Excellence and Special Recognition. The seventy-nine award winners were selected from over 12,000 organizations that partner with the Energy Star program to improve the energy efficiency of products, homes, buildings and businesses.

Energy Star Solutions

In 2007, Americans, with the help of Energy Star, saved $16 billion on their energy bills and avoided greenhouse gas emissions equivalent to those of 27 million vehicles. To date, more than 2.5 billion Energy Star-qualified products have been sold, and nearly 840,000 new homes and 4,000 office buildings, schools, hospitals, and public buildings have earned the Energy Star. Energy Star-qualified products, homes, and buildings provide the quality, features, and personal comfort today's consumers expect.

Energy Star was introduced by the U.S. Environmental Protection Agency in 1992 as a voluntary market-based partnership to reduce greenhouse gas emissions through increased energy efficiency. Today, in partnership with the U.S. Department of Energy, Energy Star offers businesses and consumers energy-efficient solutions to save energy, money, and help protect the environment for future generations.

CFL Lighting Updates for Energy Star Criteria

|
Energy Star updates in 2008:

  • Expansion of eligible product categories for CFLs,
  • New criteria limits, for the first time, the amount of mercury that CFLs can contain to less than 5 milligrams for most bulbs,
  • Includes candelabra-based CFLs
  • Incorporates a third-party testing program for all bulbs effective in November of 2008,
  • Tightens lamp color requirements and
  • Adds high-heat testing requirements for reflector products.

Revised ENERGY STAR® criteria for CFLs takes effect December 2, 2008 - 270 days from issuance of criteria. The criteria for CFLs were last updated in 2003.

These CFL products under the ENERGY STAR® label — which include new categories for CFLs that contain less mercury, new candelabra products and more rigorous testing procedures — are expected to save Americans approximately $30 billion in utility costs over the next five years. More stringent criteria, combined with a greater diversity of energy-saving product options, will allow Americans to more efficiently use energy in their homes.

Clothes Washers with Energy Star Ratings

U.S. Department of Energy Implements More Stringent Criteria for ENERGY STAR® Clothes Washers, Expands CFL Program


The U.S. Department of Energy (DOE)  announced more stringent criteria for clothes washers under the ENERGY STAR® label in 2008.

Based on first-year projected sales data, approximately 1.9 million ENERGY STAR®-qualified clothes washers will be sold, saving American families up to $92.4 million annually on their water and utility bills.

The more stringent requirements for clothes washers carrying the ENERGY STAR® label will take effect in two phases. In order to qualify, clothes washers must be a minimum of 43 percent more efficient than current federal energy efficiency standards with a maximum Water Factor (WF) of 7.5, as of July 1, 2009. As of January 1, 2011, clothes washers must be a minimum of 59 percent more efficient with a maximum WF of 6.0. WF measures the water efficiency and is calculated as gallons of water used per cubic foot of capacity – the lower the WF, the more efficient the clothes washer.

Following the 2011 criteria change for clothes washers, consumers are expected to save $120 million on utility bills annually, 11.2 billion gallons of water and 659 million kilowatt hours of electricity.

Current ENERGY STAR-qualified clothes washers use 75 percent less energy than clothes washer models manufactured in 1980. The ENERGY STAR® criteria for clothes washers, last modified in January 2007, were drafted with input from stakeholders and public review and comment.
