ASHRAE Issues List of Proposed Revisions For Ventilation and Energy

ASHRAE has issued an Update on ASHRAE Standards for Ventilation and Energy.  In addition, the letter indicates the anticipated public review dates for the Addendum being considered to the standards. 

For Energy Standards, the public comment period has passed for many of the addenda.  However, the public comment period is still open or anticipated for many areas.  In addition, the ventilation Addenda are anticipated to become open for public comment on September 11, 2009.

Department of Energy Requires ASHRAE 90.1-2004

TheUS Department of Energy announced their finding that ASHRAE 90.1-2004 is the new energy efficiency standard that all Commercial Building Codes must now meet.  This statement, therefore, requires all State building codes to be updated from the ASHRAE 90.1-1999 Standard.  In its statement, the DOE stated that there are significant differences between the 1999 and 2004 editions.  The DOE analysis found that under the new standard, energy efficiency within a building should improve by 13.4% and should improve by 11.1% when considering site energy.

What the DOE does not discuss is the effect on commercial building codes from the recent trend to require LEED compliance.  The DOE does not discuss the cost of complying with both the newer ASHRAE standards and LEED at the same time.  Under the new LEED standards, energy efficiency has a more prominent role.  However, there are still large disconnects between ASHRAE and LEED.

ASHRAE Forms New Committee For Green Buildings

ASHRAE and the USGBC were working together on ASHRAE Standard 189.1.  However, it was reported prior to the 2008 GreenBuild Conference that the two groups could not find common ground and the ASHRAE representatives "walked out" on the meetings.

It now appears that the groups are trying to make an attempt at working together once again.  Proposed Standard 189.1 will provide minimum requirements for the design of high-performance new construction and major renovation projects.  ASHRAE, along with the USGBC and the Illuminating Engineering Society of North America (IESNA) are developing the standard.

ASHRAE stated that the new committee was formed to better address varied areas covered by the proposed standards.

 

Dingell Issues Draft of New Energy Bill--Cap and Trade, Energy Efficiency, Carbon Trading, Climate Change Addressed

Representative John Dingell (D-MI), the powerful chairman of the House Energy and Commerce Committee, issued a "Discussion Draft" Energy Bill.  The bill addresses Cap and Trade, Carbon Market oversight, Greenhouse Gas standards, Energy Efficiency in buildings, and Climate Change.  The bill is over 460 pages long and if enacted will substantially change the market for energy.

CAP AND TRADE

Relevant to the Development industry, the bill contains a list of "covered entities" that may be subject to the cap and trade regime.  One "covered entity" is "any electricity source".  An electricity source is defined as a stationary source that includes one or more utility units.  A utility unit is a fossil-fuel combustion device that produces electricity for sale (i.e., not a fuel cell).  Also, the bill specifically excludes fossil fuel-fired cogeneration devices (steam and electricity) unless the unit supplies more than 1/3 of its potential electric output capacity and more than 25 MW of electric output for sale.  Another "covered entity" is a stationary source that produces more than 25,000 tons of carbon dioxide.  Finally, a "covered entity" includes any local distribution company (gas company) that delivers 460,000 cubic feet or more of natural gas to commercial and residential customers.    Based on these definitions, actual development projects and buildings are not within the realm of a "covered entity".  However, the costs of energy being supplied to consumers will be affected because every electricity source, other than most distributed generation, will fall under the Cap and Trade regime.

Energy Efficiency

The most interesting part of the proposed bill is the Energy Efficiency sections (which do not start until page 337).  The bill proposes to establish a State Energy Efficiency Development (SEED) Fund. Under the Fund, the EPA would offer low-interest or zero-interest loans to increase energy efficiency in new and existing commercial building.  The SEED money can be used by owners and to the tenants of portions of buildings.  In order to qualify for a zero-interest loan, the building must become Energy Star designated or undergo a 30 percent reduction in energy use.  Otherwise, the loan remains a low-interest loan. 

In order to qualify for Energy Star, energy efficiency would need to be increased by 25% over current levels and lighting and HVAC can only be 50% of the qualifying criteria.  Existing Energy Star buildings will remain certified for 5 years from passage of the bill.

In addition, the DOE is required to update and better label buildings for purposes of benchmarking energy usage by building type and climate area.  Eventually all new and most existing buildings will be energy labeled.

Finally, the bill contains a requirement for updates to State Building Codes.  Specifically, the national model building code would be updated every 3 years.  The bill requires energy savings as compared to ASHRAE 90.1-2004 as follows:  30% by 2010, 50% after 2020.  Further, each state must certify that is has updated its building code to comply with energy efficiency standards.  Specifically, state building codes must meet or exceed ASHRAE 90.1-2007 for energy savings.  Each state building code must meet or exceed the national building code once it is updated.  The federal government will make $50 million available to the states for this effort.  Incentive funding of up to $500,000 will be made available to each state for compliance efforts.
