‘Systems Approach’ Next?
Insurers Feel Heat of Climate-Related Risks
BERKELEY, Calif.—The insurance industry, the world’s largest business with $4.6 trillion in revenues, is making larger efforts to manage climate change-related risks, according to a new study published last month in the journal Science. “Weather- and climate-related insurance losses today average $50 billion a year. These losses have more than doubled each decade since the 1980s, adjusted for inflation,” says the study’s author Evan Mills, a scientist at Lawrence Berkeley National Laboratory (LBNL). “Insurers have become quite adept at quantifying and managing the risks of climate change, and using their market presence to drive broader societal efforts at mitigation and adaptation.” Hurricane Sandy is only the most recent U.S. example of the kinds of increasing liabilities posed by severe weather events in a changing climate.

AHRI is in the process of forming a new working group to address systems approaches and will work closely with Standard 90.1. Source: ASHRAE News Release

90.1 Proposal Boosts Efficiency Of Air-Cooled Chiller in 2015
ATLANTA—Chiller efficiencies for air- and water-cooled chillers would be increased to more than 20% under a proposed addendum to the ASHRAE/IES energy standard. Proposed Addendum ch to Standard 90.1-2010 is a continuation of the efficiency improvements that were implemented in 2010, according to Dick Lord, a member of the committee who developed the proposal through a working team of the AHRI chiller section. In 2010, a Path B was added to the standard for part-load intensive water-cooled chillers. Proposed Addendum ch adds requirements to include air-cooled chillers. If approved, the new efficiency requirements would go into effect on Jan. 1, 2015. The proposed eff iciency requirements in Addendum ch increase annual energy savings to 23.1% vs. Standard 90.1-2004 and 8.3% vs. Standard 90.1-2010. Lord noted the average payback was calculated at 6.3 years, given some units that exceed the scalar limits. Chiller manufacturers are aware of this and know that redesign and cost reduction will be required, but do support the proposal, he said. Lord also noted that we are reaching maximum technological
