NIH Policy Promotes Energy Conservation and 
Improved Reliability for Ultra-Low Temperature Freezers
 
NIH Manual Chapter 261016-16 details how to manage ultra-low temperature (ULT) freezers at NIH.  The purpose of the policy is to promote energy efficiency and energy conservation, while improving the reliability of cold storage across NIH facilities.  Benefits include lower operating costs, and improved functionality of freezers leading to fewer freezer malfunctions and failures.
 
In Brief, the Manual Chapter states:

The NIH will preserve and protect the viability of research materials in cold storage in an energy efficient manner. This policy:
 
(1) requires the selection of energy efficient ULT freezers when acquiring new units;
(2) requires all ULT freezers to be listed in the NIH Property System, and when no longer needed, disposed of according to property disposal requirements;
(3) requires regular maintenance to be performed on all ULT freezers; and
(4) directs the placement of ULT freezers in locations that are adequately ventilated, temperature controlled, and away from excessive foot-traffic.

Energy Star Certified Ultra-Low Temperature Freezers

The US Environmental Protection Agency has included ULT freezers in the Energy Star program.  NIH Manual Chapter 26101-16 requires the selection of an energy efficient model when purchasing a new ULT freezer.  To meet this requirement all new ULT freezers purchased at NIH must be Energy Star Certified.


ULT Freezer Predictive Monitoring

The NIH is currently researching predictive monitoring systems for Ultra-Low Temperature (ULT) Freezers.  More information on predictive monitoring can be found at the link below.


This policy further establishes the procedures for the inspection of NIH facilities to ensure compliance with this policy; to note deficiencies; and to remedy non-compliant occurrences.
