减少加热和冷却能量

光明力量

Bright Power是为建筑业主和运营商提供战略能源解决方案的全国领导者。该组织的使命是提高建筑物的价值和性能，提高居住者的舒适度、健康和生产力，并消除对气候的负面影响。

与纽约的许多办公楼一样，Bright Power 的租赁空间面临着同时供暖和制冷的挑战，因为不受控制的周边辐射和恒温器上的包装空调。

该建筑的系统包括独立控制的恒温散热器阀和一个成套的空调装置。频繁的同时加热和冷却以及缺乏控制浪费了能源并导致乘员不适。

Bright Power 让 75F 参与试点，以控制空间的不同系统，目标是减少能源浪费、提高舒适度，并评估基于物联网的控制如何帮助 Bright Power 的商业和多户家庭客户实现同样的目标。该公司还需要一个可以与 Tunstall 散热器产品一起安装的开源解决方案。

75F 部署了一个比例积分 (PI) 回路来控制 15 个蒸汽散热器和一个过时的 10 吨成套空调装置的恒温、占用调度控制。作为每个 75F 安装的标准配置，Bright Power 还可以访问 75F 的 Web 和移动应用程序 Facilisight，以实现安全的、产品组合范围内的建筑洞察和控制。

十个区域的硬件包括一个中央控制单元、九个智能节点、八个智能温度传感器、两个 E10001 多抽头变压器和一个 S10013 气流温度传感器。 Tunstall 产品包括 VAO 24（常开）24 伏电动执行器。其他合作伙伴是 L&S Energy Services 和 RSE Energy Group LP。

• The implementation of 75F's IoT-based solution effectively controlled the disparate systems by eliminating simultaneous heating and cooling and dramatically reducing equipment runtimes. Bright Power's heating and cooling systems now work consistently and effectively, and occupants work in a space without dramatic hot and cold spots. Building operators also have centralized visibility and control over their space, and an open-source system that poses no limits to future integrations. The solution also aligns with the Local Law 97, which aims to reduce emissions by 40 percent in New York's largest buildings by 2030, and 80 percent by 2050. The IoT-based building controls will be the most economical and effective strategy to reduce HVAC emissions and bring buildings closer to Local Law 97 requirements.

• Reduced radiator operation from 86% to 52% during occupied times and 16% during unoccupied times.
• Projected annual fan savings of approximately 9,630 kWh.
• Air conditioning compressor savings of approximately 3,505 kWh.
