New ASHRAE/IES energy standard achieves savings reduction
Atlanta — The requirements of the 2013 revision of an energy standard recently published by ASHRAE and IES will result in buildings that could achieve 6% to 8% more efficiency than buildings built to the 2010 standard.
Published in October 2013, ANSI/ASHRAE/IES Standard 90.1-2013, Energy Standard for Buildings Except Low-Rise Residential Buildings, provides minimum requirements for the energy-efficient design of buildings except low-rise residential buildings.
Pacific Northwest National Laboratories (PNNL), in support of the Department of Energy’s Building Energy Codes Program, conducted the energy savings analysis on 110 addenda included in the standard.
PNNL’s analysis shows that the site and energy cost savings are 37.7% and 37.8%, respectively, by using the 2004 standard as baseline for the regulated loads only. For the whole building energy consumptions, national aggregated site energy savings are 29.5% and energy cost savings are 29.0%.
On a nationally aggregated level, building-type energy savings range from 19.3% to 51.9% and energy-cost savings from 18.6% to 50.6%. These figures include energy use and cost from the whole building energy consumptions including plug and process loads.
The energy reduction was achieved through 33 addenda related to major changes to requirements regarding building envelope, lighting, mechanical and the energy cost budget. The most significant changes are:
Building Envelope. Opaque elements and fenestration requirements have been revised to increase stringency while maintaining a reasonable level of cost-effectiveness.
Lighting: These changes include improvements to daylighting and daylighting controls, space-by-space lighting power density limits, thresholds for toplighting and revised controls requirements and format.
Mechanical: Equipment efficiencies are increased for heat pumps, packaged terminal air conditioners, single package vertical heat pumps, air conditioners and evaporative condensers. Also, fan efficiency requirements are introduced for the first time.
Additional provisions address commercial refrigeration equipment, improved controls on heat rejection and boiler equipment, requirements for expanded use of energy recovery, small motor efficiencies and fan power control and credits. Control revision requirements have been added to the standard such as direct digital controls in many applications.
Sprouts Farmers Market, Athleta among brands in expansion mode
New York — Phoenix-based Sprouts Farmers Markets Inc. is expanding. The natural-foods supermarket chain expects to open 22 to 24 stores in fiscal 2014, including five locations in the Atlanta area.

Target CIO resigns; chain to overhaul info security
New York — Target Corp.’s chief information office, Beth Jacob, is resigning, effective Wednesday, as the retailer continues to deal with the fallout from its widespread data breach. The resignation came as Target said it is overhauling its information security practices.
“While we are still in the process of an ongoing investigation, we recognize that the information security environment is evolving rapidly,” said Gregg Steinhafel, chairman, president and CEO, Target, in a statement released by the chain. “To ensure that Target is well positioned following the data breach we suffered last year, we are undertaking an overhaul of our information security and compliance structure and practices at Target.”
As a first step in this effort, Steinhafel added, Target will conduct an external search for an interim CIO to help the retailer through its transformation.
Target also said it is working with an external adviser, Promontory Financial Group, to help it evaluate its technology, structure, processes and talent as part of the overhaul.
“We will also be elevating the role of the chief information security officer and hiring externally for this position,” Steinhafel said. “Additionally, we will be initiating an external search for a chief compliance officer.”
Previously, compliance duties were overseen by Target’s current VP of assurance risk and compliance, who already announced plans to retire at the end of March. With the overhaul, Target will separate the responsibility for assurance risk and compliance.
Jacob was appointed CIO of Target in 2008. In her resignation letter to Steinhafel, Jacob said resigning was a "difficult decision," but that "this was a time of significant transformation for the retail industry and for Target," the Associated Press reported. She did not mention the breach.
