     自上世纪90年代绿色建筑概念提出以来,衍生了低碳建筑、近零能耗建筑、零排放建筑和“碳中和“建筑等概念。实现碳中和建筑的路径,主要包括能源生产端和能源消费端两部分。建筑碳排放上表现出直接碳排放和间接碳排放,对应的实现路径可以概括为需求减量,超高能效和能源替代三方面。汇报通过五个建筑案例探讨了从超低到近零的建筑实践。最后展示天津大学十项全能竞赛的建筑小屋R-cells的剖面概念草图,希望用绿色设计助力实现建筑领域碳中和。

Since the concept of green building was put forward in the 1990s, it has derived such concepts as low-carbon building, nearly zero energy consumption building, zero emission building and "carbon neutral" building. The path to achieve carbon neutral building mainly includes two parts: energy production end and energy consumption end. Building carbon emissions show direct carbon emissions and indirect carbon emissions, and the corresponding realization path can be summarized into three aspects: demand reduction, ultra-high energy efficiency and energy substitution. The report explores architectural practices from ultra-low to near zero through five architectural cases. Finally, the section concept sketch of R-Cells, an architectural cabin in the decathlon competition of Tianjin University, is presented in the hope of helping to achieve carbon neutrality in the field of architecture with green design.

     健康中国2030提出建设健康中国的战略主题。对于建筑行业而言,需要提高建筑室内空气、水质、隔声等健康性能指标,提升建筑视觉和心理舒适性。报告强调要了解病态建筑综合症的相关概念,并根据健康建筑评价标准,同时结合环境智能控制、智慧运维发展,打造绿色高质量健康的建筑。汇报还展示了天津大学联队追求健康生态居住目标的阳光小屋R-CELLS,以及小屋采用的健康生态技术和房屋智能模式。

Healthy China 2030 puts forward the theme of Building a Healthy China. For AEC industry, it is necessary to improve health performance, such as the Indoor Air Quality (IAQ), water quality, sound insulation, as well as the visual and psychological comfort. The report emphasized on the necessary to understand Sick Building Syndrome (SBS) from the perspective of architecture, and then integrate intelligent monitoring, control, and maintenance to achieve quality buildings according to Assessment Standard for Healthy Buildings. The R-CELLS, designed by TEAM Tianjin U+, aims to achieve the goal of healthy and ecology. It is worth mentioning that ecological technology and the intelligent operation model applied in the house will ensure a good and healthy life for residents.

     未来建筑新型能源系统是能与电网对话的系统,考虑未来高比例可再生能源的发电形态,如果建筑用电根据可再生能源发电变化而变化,也就是荷随源动。这样,建筑消费的电就是绿色电力,建筑即为零碳建筑。2018年清华大学江亿院士领衔20余家企业建立了直流建筑联盟,提出“光储直柔”这一未来建筑新型能源系统,其中:“光”指分布式光伏发电,“储”指使建筑具备一定的储能的能力,“直”指通过低压直流配电系统,“柔”指为解决发电端的“刚”,当电器设备感知到外界电力供应处于高峰或紧张时,在满足舒适条件的同时,设备自动降低功率运行。根据实际应用测试,“光储直柔”可以大幅提高光伏能源的利用率。R-CELLS中应用了“光储直柔”技术,是一个能与电网对话互通的新型系统,希望在张家口完成正式搭建后,能运行过程中充分利用光伏发电和储能,通过直流母线的便捷式控制,形成和电网的柔性互动,实现零碳目标。

The new energy system for buildings in the future should be able to interact with the grid. Based on the prediction that renewable energy accounts for a large proportion in the future, electricity consumption of buildings is expected to change with the inflation of renewable energy generation. That is, consumption changes with electricity generation. In this case, electricity consumed is green, and the buildings is zero-carbon buildings. In 2018, academician Jiang Yi from Tsinghua University launched Alliance of Building Direct Current, proposing an innovative type of building energy system: Photovoltaic + Energy-storage+ Direct Current + Flexibility (PEDF). It was emphasized that direct current produced by photovoltaic can be used flexibly with the assistance of energy storage device, which make it possible to match the electricity demand to the ability of electricity supply. For example, at the peak hour of electricity supply, less power is required to maintain room comfort conditions. According to the actual application test, PEDF can greatly increase the utilization rate of photovoltaic energy. The R-CELLS house, equipped with PEDF, has the potential to interact with the grid, making full use of the photovoltaic power and energy storage devices with only one circuit easily controlled during the operation in Zhangjiakou, and will achieve the goal of zero carbon emission.

     木结构建筑在我国古代建筑史上占有重要地位,当代木结构建筑具有得房率高、工期短、节能、环保的优势。但是我国现行木结构建筑标准多从结构、力学、材料方向出发,缺乏关于木结构热工的专门标准。木结构建筑也需要利用“多能源协同、多技术耦合”的分布式功能系统来进行协调,对建筑供需能源、动态平衡等的分析非常重要。目前对内蒙古木结构建筑通水墙体的性能研究发现,冬季通水墙相当于提升室外温度15℃。关于相变材料的选择、内部流体的分布、蓄热放热性能、结构优化等研究还在进行中,后续会继续分享。

Wood structure buildings play an important role in the history of ancient Chinese architecture. And wood structure buildings in contemporary have the advantages of larger housing area availability, short construction period, energy saving and environmental protection. However, standards in China about wood-structure buildings lay much emphasis on structure, mechanical properties, rather than on thermal aspects. It is essential to balance energy demand and supply through multi-energy coordination and multi-technology integration. The current research on the performance of water-passing walls of wood-structured buildings in Inner Mongolia has found that the use of water-passing walls in winter are equivalent to raising the outdoor temperature by 15℃. Further study on the selection of Phase Change Material (PCM), internal fluid distribution and heat storage, is being conducted and will be reported in the future.

     我国仍处于工业化、城镇化的关键阶段,在2060年实现“碳中和”目标需要更陡峭的节能减排路径。园区是我国工业发展的重要载体,“亦荷亦源”的综合能源系统,是综合能源系统领域应用发展和投资建设的重点。而户侧综合能源规划面临技术、体制、政策、能水平发展等风险因素的制约,报告提出了规划体系架构方法,以考虑设备变工况、多阶段、能源价格随机性、多主体博弈、数据驱动等内容的用户侧综合能源系统规划方法建议。

China is still at the critical stage of industrialization and urbanization, which means a remarkably energy-saving and emission-reduction path to achieve the goal of "carbon neutrality" by 2060 is required. For industry parks campus, it is significant to develop integrated energy production-consumption systems. However, energy planning involves many risks such as multiparty participants, technologies, social strategies and organization. It is proposed that energy planning should be based on variable operation conditions, energy price randomness, multiparty game, data-driven, etc.

建筑:从低能耗高能效迈向灵活用能

From energy-efficient low-energy buildings to energy flexible buildings

     建筑电气化是低碳能源革命重要组成部分,是实现碳中和的重要手段。目前我国风电、光电发电量占比将逐年提高,预计2025年将达到16.5%左右。为应对风电、光电的波动性和不确定性,需要大幅提升电力系统的灵活性,用户侧灵活性的提升具有极大的潜力空间。从电网角度,灵活响应大概有负荷削减、负荷转移、现场发电、频率响应这四类。响应能力随空调负荷增加而增加,空调负荷的准确预测对于灵活响应非常重要,此外灵活响应的实现还需要包括数据分析、优化调控、需求响应、策略执行及反馈、运行评估等模块的建筑能源综合调度,以及包括状态感知和功率控制等模块的空调系统智能运控。

Building electrification is an important part of the low-carbon energy revolution and an important means to achieve carbon neutrality. In China, the proportion of wind power and photovoltaic power generation will increase yearly, and it is expected to reach 16.5% by 2025.

To address the volatility and uncertainty of wind power and photovoltaic power generation, it is necessary to improve the flexibility of the power system. Generally, there are four types of flexible response: load shedding, load shifting, on-site power generation, and frequency control. It has been proved that the response ability of air conditions increases with the increase of cooling and heating load. Therefore, it is significant to predict the load as accurate as possible. In addition, the realization of flexible response also requires integrated building energy scheduling including data analysis, optimization control, demand response, strategy execution and feedback, operation evaluation and other modules, as well as intelligent operation and control of the air conditioning system including status perception and power control modules.


     专家们的精彩报告吸引了来自天津大学联队师生、设计院、赞助企业代表、参展商和会展观众等来自各方的听众。大家在茶歇时间讨论着R-CELLS项目及其背后的设计与技术理念。

The awesome presentations attracted many audiences including teachers and students from TEAM Tianjin U+, representatives of design institutes and sponsoring companies, exhibitors and exhibition visitors. Everyone was discussing the design and technology of R-CELLS during the tea break.
