The MVZ Genetic Resources Collection currently is maintained in electrically powered ultra-cold freezers, but will be transitioned in this project to liquid nitrogen freezers. Liquid nitrogen freezers are superior to ultra-cold freezers in several respects, including (1) lack of dependence on electricity to maintain temperature (a critical safeguard should there be an extended loss of electricity following an earthquake on the nearby Hayward Fault), and (2) samples are maintained at -150 degrees C (eliminating tissue degradation that persists at -80 C ultra-cold temperatures). The entire collection (encompassing ~100,000 tissue vials) also will be inventoried and bar-coded.The genetic resources collection is among the largest tissue collections in the world, with worldwide geographical coverage. It is a resource for researchers throughout the world who undertake genetic studies of vertebrate species, and includes samples representing extinct species, as well as populations extirpated by anthropogenic habitat modification and infectious disease. This project will substantially reduce the energy usage and carbon footprint of the Berkeley campus. The UC Berkeley Office of Sustainability, the Campus Climate Action Partnership (Cal CAP), and the Strategic Energy Plan will showcase it as an example of how careful management of energy emissions can be undertaken without compromising academic research.

MVZ遗传资源收藏目前保存在电动超冷冷冻机中，但在本项目中将过渡到液氮冷冻机。液氮冷冻机在几个方面上级超低温冷冻机，包括（1）不依赖电力来维持温度（如果附近的海沃德断层发生地震后电力损失延长，这是一个关键的保障措施），以及（2）样品保持在-150摄氏度（消除在-80摄氏度超低温下持续存在的组织降解）。整个收藏品（包括约100 000个组织小瓶）也将被清点和条形码化。遗传资源收藏品是世界上最大的组织收藏品之一，地理覆盖全球。它是全世界从事脊椎动物物种遗传研究的研究人员的资源，包括代表灭绝物种的样本，以及因人类栖息地改变和传染病而灭绝的种群。该项目将大大减少伯克利校园的能源使用和碳足迹。加州大学伯克利分校可持续发展办公室，校园气候行动伙伴关系（Cal CAP）和战略能源计划将展示它作为一个例子，说明如何在不影响学术研究的情况下仔细管理能源排放。
