「英中对照」Willmott Dixon的Energy Synergy建筑性能管理服务获CIBSE两项奖 已监测50个项目

Reflecting its vision of better-performing buildings for society and the environment, CIBSE expanded its annual awards this year to include two new categories: Building Performance Evaluation – Practice; and Building Performance Evaluation – Product or Innovation of the Year.反映了其为社会和环境打造更高性能建筑的愿景，CIBSE 今年扩大了年度奖项，新增两个类别：建筑性能评估——实践类；以及建筑性能评估——年度产品或创新类。

Contractor Willmott Dixon won both the Building Performance Evaluation – Practice and the CIBSE Next Generation of Building Performance Award with its Energy Synergy building performance management service.承包商 Willmott Dixon 凭借其 Energy Synergy 建筑性能管理服务，同时赢得了建筑性能评估——实践类奖项和 CIBSE 下一代建筑性能奖。

Designed to monitor operational energy and close the performance gap between design and in-use operation, judges hailed Energy Synergy as an excellent example of building performance monitoring and said it demonstrated best practice in a ‘reliable, replicable and scalable way’.该服务旨在监测运行能耗，弥合设计与实际使用运行之间的性能差距。评委称赞 Energy Synergy 是建筑性能监测的杰出典范，并表示它以“可靠、可复制、可扩展的方式”展现了最佳实践。

The system now monitors 50 projects and those with 12 or more months of data show an average 15% better-than-predicted performance compared with TM54 projections.该系统目前监测 50 个项目，其中拥有 12 个月或更长时间数据的项目与 TM54 预测值相比，平均性能比预测结果好 15%。

Bassaleg School, South Wales, shows what can be achieved. Actual energy use is 21% less than predicted at design stage, which has resulted in annual energy savings of 327,204kWh, savings of 65.11 tonnes CO₂e, and a £98,161 reduction in energy bills.南威尔士的 Bassaleg 学校展示了可实现的成果。实际能耗比设计阶段预测值低 21%，由此每年节约 327,204kWh 能源，减少 65.11 吨 CO₂e，并使能源费用降低 £98,161。

Under the hood核心机制

Energy Synergy monitors all aspects of energy performance, including heating, ventilation, small power and DHW. The process is integrated into a BMS to capture energy-use data, typically over a three-year, post-occupancy period. The service enhances customers’ BMS rather than replaces it, and clients retain full ownership and control of data.Energy Synergy 监测能源性能的各个方面，包括供暖、通风、小功率用电和 DHW。该流程集成到 BMS 中，以 采集能源使用数据，通常 在三年的入住后期间进行。该服务增强而非替换客户的 BMS，并且客户保留对数据的完整所有权和控制权。

There are three stages to Energy Synergy. Stage 1 is CIBSE TM54 performance modelling, where engineers work with CIBSE-affiliated consultants to develop achievable energy benchmarks.Energy Synergy 分为三个阶段。第一阶段是 CIBSE TM54 性能建模，由工程师与 CIBSE 附属顾问合作制定可实现的能源基准。

Stage 2 is BMS integration and comprehensive metering. Sub-metering, and measurement and verification after construction, are key to closing the performance gap.第二阶段是 BMS 集成和全面计量。施工后的分项计量以及测量与验证，是弥合性能差距的关键。

Stage 3 is the creation of an AI-supported dashboard, which allows users to identify inefficiencies and optimise performance. Hollycroft Primary School, Leicestershire, benefited from this monitoring when data revealed a mechanical failure in a pump, which was causing inadequate hot-water circulation. By isolating this specific component failure, the school avoided a wider performance decline and restored occupant comfort.第三阶段是创建由 AI 支持的仪表盘，让用户能够识别低效问题并优化性能。莱斯特郡的 Hollycroft 小学从这种监测中受益：数据显示一台泵发生机械故障，导致热水循环不足。通过隔离这一特定部件故障，学校避免了 更大范围的性能下降，并恢复了室内人员的舒适度。

Among the other projects using Energy Synergy is Ysgol Gynradd Glyn-Coch primary school in South Wales, which is planned to be completed in February 2027. 使用 Energy Synergy 的其他项目包括南威尔士的 Ysgol Gynradd Glyn-Coch 小学，该校计划于 2027 年 2 月完工。

This 300-pupil, two-storey building, designed by architect Stride Treglown, brings together pupils from two existing schools, and includes a nursery and community hub.这座可容纳 300 名学生的两层建筑由建筑师 Stride Treglown 设计，将两所现有学校的学生 汇聚在一起，并设有托儿所和社区中心。

The school was part of the UK Net Zero Carbon Buildings Standard (UK NZCBS) pilot scheme, under which contractors and engineering teams tested the standard’s draft framework on real-world projects.该校是 UK Net Zero Carbon Buildings Standard（UK NZCBS，英国净零碳建筑标准）试点计划的一部分；根据该计划，承包商和工程团队在实际项目中测试该标准的框架草案。

The UK NZCBS is a framework that provides unified, verifiable performance limits aligned with the UK’s 1.5°C carbon budgets. It covers 15 building types, including education buildings (see panel, ‘Limits and targets for schools’).UK NZCBS 是一个框架，提供与英国 1.5°C 碳预算相一致的统一、可验证性能限值。它涵盖 15 种建筑类型，其中包括教育建筑（见专栏“学校的限值与目标”）。

The school is being built to the Passivhaus standard and will be certified. The methodology focuses on energy efficiency, exceptional thermal comfort and superior indoor air quality through fabric-first design principles. The design features an air source heat pump for space heating, while ventilation with heat recovery is provided by two AHUs and four mechanical ventilation with heat recovery units.该校正按 Passivhaus 标准建造，并将获得认证。该方法通过围护结构优先的设计原则，聚焦于能源效率、卓越的热舒适度和优异的室内空气质量。 设计采用空气源热泵进行空间供暖，同时由两台 AHUs 和四台机械热回收通风机组提供热回收通风。

Under Version 1 of the UK NZCBS, Passivhaus certification is recognised as a ‘deemed to satisfy’ route at practical completion for direct space heating – Passivhaus’s core threshold of 15kWh·m^-2 per year satisfies the UK NZCBS limit – and energy-use intensity (EUI). The school’s space heating demand is predicted at 13kWh·m^-2 per year and is currently on track to be lower still.根据 UK NZCBS 第 1 版，Passivhaus 认证在实际竣工时被认可为直接空间供暖与能源使用强度（EUI）的“视为满足”路径——Passivhaus 每年 15kWh·m^-2 的核心阈值满足 UK NZCBS 限值。该校的空间供暖需求预计为每年 13kWh·m^-2，且目前有望进一步降低。

Passivhaus’s strict quality assurance ensures that the predicted design EUI in the Passivhaus Planning Package (PHPP) energy modelling service closely matches the actual metered EUI on the site.Passivhaus 严格的质量保证可确保 Passivhaus 规划包（PHPP）能耗建模服务中预测的设计 EUI 与现场实际计量的 EUI 高度吻合。

‘As the school was already targeting Passivhaus certification, this gave us a comfortable buffer against the standard’s operational energy limit,’ says Doug Drewniak, principal sustainability manager, building performance, at Willmott Dixon.Willmott Dixon 负责建筑性能的首席可持续发展经理 Doug Drewniak 表示：“由于该校原本就以 Passivhaus 认证为目标，这为我们对照该标准的运营能源限值留出了充足缓冲。”

The building comfortably achieved the 2025 NZCBS embodied carbon (EC) limit for schools of 530kgCO₂·m^-2 and also the Wales Government’s 2030 EC target of <350kgCO₂·m^-2 (as a Sustainable Schools Challenge Project).该建筑轻松达到了 2025 NZCBS 针对学校的隐含碳（EC）限值 530kgCO₂·m^-2，同时也达到了威尔士政府 2030 年 EC 目标 <350kgCO₂·m^-2 （作为“可持续学校挑战项目”）。

“The performance gap between design and in-use operation is not inevitable” “设计与实际使用运行之间的性能差距并非不可避免” 

It was a challenge however – for example, more structural steel than expected was required to support the roof plant loading and large classroom spans. This meant the upfront EC figure increased, as did the thermal bridging value in PHPP, resulting in a small operational energy penalty.然而这是一项挑战——例如，为承受屋顶设备荷载和教室的大跨度，需要使用比预期更多的结构钢。这导致前期 EC 数值上升，PHPP 中的热桥值也随之增加，从而在运营能耗方面造成轻微不利影响。

Drewniak said the project benefited significantly from having a single consultant/coordinator leading the process and requiring assessments.Drewniak 表示，该项目极大地受益于由一名顾问/协调员牵头整个流程并要求开展评估。

‘Issues were overcome by our excellent consultant Mark Morant, from Arda Consulting. “各种问题都由我们来自 Arda Consulting 的出色顾问 Mark Morant 化解了。

Another ‘operational reality’ was the higher energy demand linked to the Welsh Government’s Universal Primary Free School Meals policy. The compact Passivhaus form meant there was not enough room on the roof to install the PVs that would have offset the extra energy needed to provide hot dinners. A collaborative solution was found by installing panels in a south-facing canopy, says Drewniak.另一个“运营现实”是与威尔士政府 Universal Primary Free School Meals 政策相关的更高能源需求。紧凑的 Passivhaus 形态意味着屋顶 没有足够空间安装 PV，本可借此抵消提供热餐所需的额外能源。Drewniak 表示，通过在朝南的顶棚安装光伏板，各方找到了协作解决方案。

Lightening the loads减轻负荷

TM54 was the bridge between design and in use, according to Drewniak. While PHPP models the envelope to ensure minimal heat escapes, TM54 models how human behaviour, equipment and occupancy schedules consume energy within that completed building.Drewniak 表示，TM54 是设计与使用阶段之间的桥梁。PHPP 对围护结构建模，以确保热量散失最少；TM54 则对竣工建筑内人员行为、设备和在室时间表如何消耗能源进行建模。

The real challenge of UK NZCBS is not the fabric, but the extra loads from catering, ICT, external lighting and community use outside of school hours, adds Drewniak, who says using TM54 to predict energy use in realistic scenarios enables an achievable target to be set. ‘Without allowing for operational factors or realistic building-use scenarios, there’s a real risk of a performance gap.’Drewniak 补充称，UK NZCBS 的真正挑战并非建筑围护结构，而是餐饮、ICT、外部照明以及课外时段社区使用所产生的额外负荷。他表示，借助 TM54 预测真实场景中的能源使用，可以设定可实现的目标。“若不考虑运营因素或真实的建筑使用场景，就 确实存在性能差距的风险。”

The second step in Energy Synergy is to create a metering process that measures and manages energy performance in use, and verifies that the TM54 design-stage target is being met. Operational data from this system can be submitted to the UK NZCBS portal to verify that a building is net zero aligned.Energy Synergy 的第二步是建立计量流程，以测量和管理使用中的能源绩效，并验证 TM54 设计阶段目标是否得到满足。该系统的运行数据可提交至 UK NZCBS 门户网站，用于验证建筑是否符合净零排放要求。

‘At Willmott Dixon, we’ve been running TM54 as the benchmark behind Energy Synergy for years. To now have a standard that is driving in-use performance feels like our approach has been vindicated’, says Drewniak, who would like as-built data used to inform design modelling in Energy Synergy.“在 Willmott Dixon，多年来我们一直将 TM54 作为 Energy Synergy 背后的基准。如今有了一项推动在用绩效的标准，感觉我们的方法得到了验证，”Drewniak 说。他希望将竣工数据用于为 Energy Synergy 中的设计建模提供依据。

‘Closing the feedback loop is big on our agenda, especially if we can leverage AI to assist that process,’ he says. Through Energy Synergy, Willmott Dixon has demonstrated that the performance gap is not inevitable. “闭合反馈回路是我们的一项重要议程，尤其是如果我们能够利用人工智能来辅助这一流程，”他说。通过 Energy Synergy，Willmott Dixon 已证明绩效差距并非不可避免。
