Decarbonization path of China’s public building sector from bottom to top

The building sector is one of the three major energy consumption areas and one of the main areas responsible for carbon emissions.In 2019,carbon emissions related to construction and building operations in China accounted for 38% of the total social carbon emissions,of which construction accounted for 16% and operations accounted for 22%.Due to its large volume and high energy consumption per unit area,public buildings account for 38% of the operating energy consumption of all buildings,that is,8% of the total national energy consumption.At this time,the building industry must take decarbonization actions to avoid a delay in realizing carbon neutrality and an emission peak.We need to form a unified process for the implementation boundary,implementation path,and index system to build a zero-carbon implementation plan for China’s public building sector.Based on bottom-up practical cases,this paper proposes the KAYA model,which is applicable to different scales and different types of public buildings/communities,and proposes specific and feasible plans.Through the implementation of demand reduction,energy efficiency improvement,and the fully-use of renewable energy in all five clear steps,this paper promotes the implementation of decarbonization in China’s building industry.

Heat prices for public buildings in Tianjin

Energy-saving awareness of heat users and heating enterprises can be stimulated by implementing heat metering for public buildings and by establishing scientific and reasonable policies for heat prices in China. In this paper, a two-part heat price for public buildings in Tianjin is introduced, which divides the heat price into a basic part and a metering part. According to the statistical analysis of information collected from two pilot heating enterprises, the specific heat load for public buildings in Tianjin is calculated, and three candidate schemes of heat price are proposed. A simulation of heat cost is also conducted, and the benefits for both heat users and heating enterprises are balanced. Finally, the two-part heat price for public buildings in Tianjin is determined： the basic heat price is recommended to be 20 CNY/mz, and the metering heat price is recommended to be 76.10 CNY/GJ. Such a price could be implemented in the initial stage of heat metering for public buildings in Tianjin.

Online Energy Measure and Analysis System for Large-Scale Public Buildings

Large-scale public buildings have high energy density, which on average consume 5 to 15 times more electricity than residential buildings. In Beijing, those public buildings account for about ten percent of the total building area, but their energy consumption （except heating） amounts to more than thirty percent of the total. Few electric meters are installed in those public buildings, however, making it more difficult to monitor how the energy is used.

Research on Two Types of Buffer Zone Impact on Surrounding Office Space Environment in Winter in Cold Climate Zone—a Fieldwork in Architectural Design Institute Building of Tsinghua University,Beijing

Building buffer zone space is not only one of essential approaches for better mental quality of interior building space, but also an important factor that may influence interior thermal comfort and energy consumption. This study aims to analyze regulative advantages of buffer zone to the surrounding functional spaces. Based on a fieldwork test in a typical office building in cold climate zone in Beijing,China,the monitor data show interior physical performance in the Winter. The research selects two types of different buffer zones in the same building. One is a south-faced greenhouse which has large dimension with plenty of vegetation,and the other is a simple atrium in the middle of five floor building with mount of skylights. The factors and their influence to surrounding functional spaces and the whole building are found out from the comparisons of collected data by floor to floor monitor test on both buffer zones at the same time. The comparisons of two types of buffer zones conclude that the greenhouse is more effective to air quality regulation but not so clearly wellperformed to thermal buffering as expected due to the dominate active central heating in the Winter. This fieldwork test results for building performance can be helpful for both architects and engineers in the early phase of sustainable design.

Peer-to-Peer Energy Trading Method of Multi-Virtual Power Plants Based on Non-Cooperative Game

The current electricity market fails to consider the energy consumption characteristics of transaction subjects such as virtual power plants.Besides,the game relationship between transaction subjects needs to be further explored.This paper proposes a Peer-to-Peer energy trading method for multi-virtual power plants based on a non-cooperative game.Firstly,a coordinated control model of public buildings is incorporated into the scheduling framework of the virtual power plant,considering the energy consumption characteristics of users.Secondly,the utility functions of multiple virtual power plants are analyzed,and a non-cooperative game model is established to explore the game relationship between electricity sellers in the Peer-to-Peer transaction process.Finally,the influence of user energy consumption characteristics on the virtual power plant operation and the Peer-to-Peer transaction process is analyzed by case studies.Furthermore,the effect of different parameters on the Nash equilibrium point is explored,and the influence factors of Peer-to-Peer transactions between virtual power plants are summarized.According to the obtained results,compared with the central air conditioning set as constant temperature control strategy,the flexible control strategy proposed in this paper improves the market power of each VPP and the overall revenue of the VPPs.In addition,the upper limit of the service quotation of the market operator have a great impact on the transaction mode of VPPs.When the service quotation decreases gradually,the P2P transaction between VPPs is more likely to occur.

Professional practice in prosramming larse public buildinss in China： A questionnaire survey

China＇s large public buildings （LPBs） often become problematic after on｜y a few years＇ operation, leading to shortened building lifespans. Lacking architectural programming was identified by the industry regulators as a contributing factor to this. Despite a policy shift on the government side since 2007, little evaluation of the actual situation has been made. To raise awareness and attention to this pressing issue from the building industry, its regulators and the general public, a questionnaire survey focusing on the top-tier sector of professional practice in programming LPBs was carried out in Shanghai, China in 2009. The objectives were to evaluate current trends and pressing issues, identify major challenges and opportunities, and make recommendations for improvement. This paper presents a six-part analysis of the survey＇s findings from 57 professionals and clients who shared their hands-on experience on various programming issues and provided first-hand data of 90 LPBs developed in the 2000s. This pioneering study revealed significant gaps between the real and best practices as well as the mentat reluctance and skill mismatch in delivering quality programming services. Given the persisting nature of identified problems, more research work should be done to catatyze a paradigmatic shift amon industry players.

The Old and the New: Designs to Enhance Cesano Maderno Old Town through a Regenerative Structure

The relationship between the old and the new is a specific theme of architecture that bears witness not so much to the original appearance of the old but to its enduring meaning in historic Italian and European cities.The complex palimpsest of signs,memories,and overwriting that time has layered on built forms opens questions of meaning that can be untangled only in the relationship between history,site and design.The investigation of structural characters of places and their relationships with cultural assets and heritage provides a layered set of readings,which is itself the forerun of an urban landscape design action.Beyond preserving the integrity of the material traces,there can only be the new.The test bench is therefore the project as a cognitive act around which to build‘case by case’the strategies for recovering urban identity.The series of projects for Cesano Maderno old town,north of Milan,exemplifies a design-led approach to the built heritage and historic urban landscape in which reading tools,conservation and design are shown in their mutual relationship.In this dialectic between the old and the new,the design is part of the architecture of time where the new,working through light reversible overwriting and measured grafting,becomes a further layer in the historical palimpsest and the authentic form of its enhancement and reuse.Integrating project strategies-from pure conservation to new architectural grafting,from reuse to overwriting-the sequence of designs give shape to a‘regenerative structure’that enhances as a system and for public use a set of introverted Baroque buildings and spaces along a historical promenade,re-centring the city around its brownfield core.
