「英中对照」距上版九年 BSRIA发布第四版BG 31/2026机械建筑服务图解指南

BSRIA has published major updates to its BG 31 The Illustrated Guide to Mechanical Building Services, providing an updated reference for construction professionals who are not specialists in the discipline.BSRIA 已发布 BG 31《机械建筑设备图解指南》的重大更新，为并非该领域专家的建筑专业人士提供最新参考。

The fourth edition comes nine years after the previous guide and reflects significant changes in regulation and technology over that period. Changes to Part L have increased the focus on energy performance and higher-efficiency building services, while heat pumps and heat networks are playing a growing role in how buildings are heated.第四版在上一版指南发布九年后面世，反映了这段时期法规和技术的重大变化。Part L 的修订使人们更加关注能源性能和更高效率的建筑设备，同时热泵和热力网络在建筑物供暖方式中的作用日益增强。

Fire safety also remains a key consideration in the design and installation of mechanical services.消防安全在机械设施的设计和安装中也仍然是一项关键考量因素。

BG 31/2026 brings these areas together with practical guidance on the heating, ventilation, cooling, hot water and control systems found in buildings. It is aimed at a broad construction audience, including project managers, manufacturers and clients who need to understand the systems without necessarily being building services specialists.BG 31/2026 将这些领域结合在一起，针对建筑物中的供暖、通风、制冷、热水和控制系统提供实用指南。其面向广泛的建筑受众，包括需要了解这些系统但不一定是建筑设备专家的项目经理、制造商和客户。

BG 31/2026 explains the ‘lean, clean and green’ approach to reducing HVAC energy use and carbon emissions, starting with reducing demand through building design before considering efficient systems and low-carbon plant.BG 31/2026 阐释了减少 HVAC 能源使用和碳排放的“精益、清洁、绿色”方法：首先通过建筑设计降低需求，然后再考虑高效系统和低碳设备。

The guide reflects the impact of Part L on the specification of higher-efficiency plant, advanced controls and sustainable technologies, as well as the balance between upfront investment and whole-life costs.该指南反映了 Part L 对更高效率设备、先进控制和可持续技术选型的影响，以及前期投资与全生命周期成本之间的平衡。

Heat pumps and heat networks feature more prominently in the new edition. The guide describes heat pumps as becoming the preferred means of heating buildings and explains their growing use in modern non-domestic buildings and new homes. It also covers low-temperature heating and the principles and operation of heat networks.热泵和热力网络在新版中的篇幅更加突出。指南指出，热泵正成为建筑物供暖的首选方式，并说明了其在现代非住宅建筑和新建住宅中日益增长的应用。内容还涵盖低温供暖以及热力网络的原理和运行。

Fire safety guidance covers compartmentation and firestopping, smoke and fire dampers, staircase pressurisation and smoke clearance, helping non-specialists to understand how mechanical services interact with a building’s wider fire safety strategy.消防安全指南涵盖防火分隔与防火封堵、排烟阀和防火阀、楼梯加压及排烟，帮助非专业人员了解机械设施如何与建筑物更广泛的消防安全策略相互配合。

The guide also provides a reference for control and building management systems, commissioning and handover, and the running costs of mechanical plant over its working life.该指南还提供了有关控制和楼宇管理系统、调试与移交，以及机械设备在使用周期内运行成本的参考。

Mechanical services typically account for 15-25% of overall build costs in standard UK commercial and residential buildings, rising above 30% in complex buildings such as hospitals and high-specification offices. The guide also highlights the importance of considering running costs and whole-life performance alongside initial capital expenditure.在英国标准商业和住宅建筑中，机械设施通常占总建筑成本的 15%–25%；在医院和高规格办公室等复杂建筑中，这一比例会超过 30%。指南还强调，在考虑初始资本支出的同时，也必须考虑运行成本和全生命周期性能。

It covers ventilation, cooling and hot water systems, as well as how buildings connect to water, gas, electricity and telecommunications networks. Each system is introduced through key points, photographs and diagrams designed to make the principles and operation easier for non-specialists to understand.内容涵盖通风、制冷和热水系统，以及建筑物如何接入供水、燃气、电力和电信网络。每个系统均通过要点、照片和示意图进行介绍，以便非专业人员更容易理解其原理和运行。

David Bleicher, publications manager, BSRIA, said: “A lot has changed in building services since the last edition was published in 2017, and it’s becoming increasingly important for people outside the discipline to understand how these systems work.BSRIA 出版物经理 David Bleicher 表示：“自上一版于 2017 年发布以来，建筑设备领域发生了许多变化。对于该专业之外的人员而言，了解这些系统如何运行正变得越来越重要。”

“While not everyone needs to be a building services engineer, if you’re involved in designing, delivering or managing buildings, you need to understand the basics. Decisions about heating, ventilation and cooling have implications for everything from energy use and running costs to fire safety and occupant comfort.“虽然并非每个人都需要成为建筑设备工程师，但如果您参与建筑的设计、交付或管理，就需要了解基础知识。供暖、通风和制冷方面的决策会影响从能源使用、运行成本到消防安全和居住者舒适度的方方面面。”

“The guide is there to make that easier. It gives professionals a practical introduction to the different systems, what they do and how they can impact broader building design, so that they can ask better questions and have more informed conversations with the specialists.”“该指南旨在让这一切变得更简单。它向专业人员实用介绍不同系统、它们的作用以及它们如何影响更广泛的建筑设计，从而使他们能够提出更好的问题，并与专家进行更有依据的沟通。”
