大学校园通常包括集中和分散的供暖和制冷系统。在试图保持乘员舒适性的同时最大限度地降低能耗时，每种配置都有其固有的优势和挑战。计算能力的最新技术进步使建筑能源建模人员能够快速高效地开发模型，这些模型可以作为集中工厂的一部分或作为独立系统进行评估。国际社会对温室气体（GHG）减排的关注影响了世界上许多国家的政策。据白宫新闻秘书称，美国的目标是到2025年使温室气体净排放量比2005年的水平低26-28%。对温室气体减排的关注已经将能源建模的好处带到了建筑设计师、管理者和决策者的最前沿。 蒙大拿州立大学位于蒙大拿州的博兹曼，气候干燥、炎热。目前，该大学运营着一座集中蒸汽处理厂，服务于59栋建筑，总面积略高于300万平方英尺。这种集中供暖系统通过一个公用隧道网络在校园内分配蒸汽。然而，冷却系统是分散的，主要使用冷却塔来散热。本文详细介绍了大学评估并随后实施的一种替代配置，以减少校园温室气体排放。该大学将一小群建筑连接起来，在大型集中校园区内形成一个能源“迷你区”。这个迷你区共有八栋建筑，总面积略超过40万平方英尺（37000平方米），占校园建筑总面积的14%。 这些建筑包含具有大量内部需求负荷的研究实验室，以及具有自然日间负荷的传统教室。在实施小型小区之前，常见的情况是，一些建筑通过冷却塔排热，而相邻建筑则需要供暖。能源迷你区使用一个中央热泵装置，带有水回路，允许建筑之间共享能源。这种配置还允许未来整合低碳能源，如太阳能热阵列和地源钻井场。使用历史公用设施数据和mini中的能源测量数据创建和调整了建筑能源模型- 地区对能源小区的评估显示，与使用带冷却塔的蒸汽加热厂的原始配置相比，温室气体排放减少了14.26%。引用:2016年冬季会议，佛罗里达州奥兰多，会议论文

Institutional campuses often times encompass both centralized and decentralized heating and cooling systems. Each configuration inherently has advantages and challenges when trying to maintain occupant comfort while minimizing energy consumption. Recent technological advancement in computing power allows building energy modelers to quickly and efficiently develop models which can be evaluated as part of a centralized plant or as a stand-alone system. International attention to greenhouse gas (GHG) emission reduction has influenced policy in many nations around the world. According to the White House Press Secretary, the United States is targeting net GHG emissions 26-28% below 2005 levels by 2025. The attention to GHG emission reduction has brought the benefits of energy modeling to the forefront of building designers, managers and policy makers. Montana State University, located in Bozeman, Montana, has a dry, heating dominated climate. Currently the university operates a centralized steam plant serving 59 buildings totaling just over 3-million square feet. This centralized heating system distributes steam across campus using a network of utility tunnels. The cooling systems, however, are decentralized and primarily use cooling towers to reject heat. This paper details an alternative configuration the university evaluated and subsequently implemented to reduce GHG emission on campus. The university interconnected a small group of buildings to form an energy "mini-district" within the large centralized campus district. This mini-district contains eight buildings totaling just over 400,000 ft2(37,000 m2) or 14% of the total campus building square footage. These buildings contain research laboratories with substantial internal demand loads and traditional classrooms having natural, diurnal loads. Before implementing the mini-district it was common to see some buildings rejecting heat through cooling towers while adjacent buildings were experiencing heating demands. The energy mini-district uses a centralized heat pump plant with water loops allowing energy to be shared between the buildings. This configuration also allows for future incorporation of low carbon energy sources such as solar thermal arrays and ground-source bore fields. Building energy models were created and tuned using both historical utility data and energy measurements within the mini-district. Evaluation of the energy mini-district shows a GHG emission reduction of 14.26% over the original configuration using the steam heating plant with cooling towers.
