The Provinciehuis Overijssel in Zwolle, the Netherlands, was built in 1972 as one of the first regional government facilities to feature large open-plan workspaces accommodating approximately 1,000 employees. To support the region's ambition to become completely energy-neutral, the building management needed to transition from a traditional climate control system utilizing gas-fired boilers and low-temperature heat pumps to a fully gas-free setup. A major technical challenge was the requirement to execute this transition without major structural modifications, specifically aiming to retain the existing terminal units such as radiators, convectors, and ceiling induction units. These existing legacy units required higher supply temperatures, complicating the integration of a sustainable heating solution.位于荷兰兹沃勒的 Provinciehuis Overijssel 建于 1972 年，是最早一批采用大型开放式工作区、可容纳约 1,000 名员工的地区政府设施之一。为支持该地区实现完全能源中性的目标，楼宇管理方需要从采用燃气锅炉和低温热泵的传统气候控制系统过渡到完全无燃气配置。一项重大技术挑战是需在不进行重大结构改造的情况下完成这一过渡，特别是要保留散热器、对流器和吊顶感应机组等现有末端装置。这些既有老旧装置需要更高的供水温度，使可持续供暖解决方案的集成变得复杂。
Implementing data-driven digital control technology
The facility faces widely varying occupancy levels due to hybrid working arrangements, making it critical to accurately monitor and automatically optimize energy consumption and climate control. Furthermore, regional regulations mandated the implementation of a Building Automation and Control System to reduce energy consumption and improve operational efficiency. To meet these demands, the installation company Heijmans and smart-building specialist bGrid collaborated with Danfoss to deploy a future-ready technical solution. The gas-fired central heating boilers were replaced with a heat pump utilizing natural refrigerants. To control the hydronic ceiling units precisely, the engineering team integrated Danfoss pressure-independent control valves combined with digital actuators. This configuration creates a dynamically balanced and self-optimizing HVAC network capable of handling fluctuating thermal loads.采用数据驱动的数字控制技术
由于混合办公安排，该设施的人员占用水平差异很大，因此精确监测并自动优化能耗与气候控制至关重要。此外，地区法规要求实施楼宇自动化与控制系统，以降低能耗并提高运营效率。为满足这些需求，安装公司 Heijmans 和智能建筑专业公司 bGrid 与 Danfoss 合作，部署了一套面向未来的技术解决方案。燃气集中供暖锅炉被采用天然制冷剂的热泵所取代。为精确控制水力吊顶单元，工程团队集成了 Danfoss 压力无关型控制阀与数字执行器。该配置构建了动态平衡、自我优化的 HVAC 网络，能够应对不断波动的热负荷。
Reduced energy consumption and operational insights
Data from the smart sensors and controllers is collected, stored, and visualized through a dedicated building management platform. This infrastructure provides building managers with floor-level insights into space occupancy, energy use, and system performance, allowing the climate control system to automatically respond to actual room usage. The deployment of this smart digital control architecture has yielded measurable operational results. The modernized system consumes approximately one-third of the energy required by the former gas boiler setup, resulting in a reduction of 200,000 kWh of gas energy annually alongside a 10 percent decrease in electricity costs. Matching equipment performance to actual occupancy, such as shutting down climate control on unused floors during low-attendance days, cuts energy consumption by more than 25 percent. Additionally, indoor comfort improved significantly, reflected in an 80 percent reduction in climate-related complaints, while operators gained the ability to continuously monitor deviations and maintain optimal indoor air quality.
降低能耗与运营洞察
智能传感器和控制器的数据通过专用楼宇管理平台进行收集、存储和可视化。该基础设施为楼宇管理者提供关于空间占用、能源使用和系统性能的楼层级洞察，使气候控制系统能够自动响应房间的实际使用情况。这套智能数字控制架构的部署取得了可衡量的运营成效。现代化改造后的系统能耗约为原燃气锅炉系统所需能耗的三分之一，每年减少 200,000 kWh 燃气能源消耗，同时电力成本降低 10 %。使设备性能与实际占用情况相匹配，例如在低出勤日关闭未使用楼层的气候控制，可减少超过 25 % 的能耗。此外，室内舒适度显著提升，与气候相关的投诉减少 80 %，运维人员也能够持续监测偏差并保持最佳室内空气质量。
