“…Property management is the operation and maintenance for the building operation stage, so its innovative path and strategy will have a great impact on the carbon emissions in the building operation stage, and if its low-carbon transformation process links the building materials production, building design and building construction stages, it will realize the carbon emission reduction in the whole process of building. [2] According to Zhao Linfu (2021), green property management includes five elements: energy saving management, water saving management, waste classification management, environmental greening management and pollution prevention management. [3] Among them, energy saving management and pollution prevention management are closely related to carbon emissions.…”

In the context of China’s strategy to promote carbon peaking and carbon neutrality, the construction industry has come under the spotlight for its higher carbon emissions. Property’ management plays an important role in the operation phase of buildings. Therefore, it is of great significance to innovate property’ management paths and strategies for energy saving and emission reduction in the property sector. In this paper, we will first discuss the concept and connotation of “dual-carbon” strategy, as well as the relationship between property’ management and carbon emissions. Secondly, it discusses the challenges faced by property’ management under the “dual-carbon” strategy and the benefits of accomplishing the transformation, in order to explain the necessity and value of innovative property’ management. Then, the three innovative paths of property’ management, namely intelligent building and energy’ management, application and promotion of renewable energy’, and carbon footprint monitoring and assessment, are discussed and the key strategies are proposed from certain perspectives. Then, successfill case of property’ management is introduced, and the experiences for their success are summarized. Finally, based on the above innovation paths, key strategies and successful cases, suggestions are made from three perspectives: policies and regulations, enterprises and owners, and technology’ and talents.

“…In this regard, Figure 1 presents the carbon emissions resulting from each of the building stages, highlighting that the carbon emissions from the operation stage account for 21% of the total in China. On this basis, it is crucial to reduce the carbon emissions from the building operation stage, as a key milestone towards achieving the goal of near-zero energy consumption [9,10]. Furthermore, the energy consumption from heating during building operations accounts for a high proportion of the total energy consumption [11].…”

A nearly zero-energy building is characterised by its low energy demand and enhanced thermal insulation, with great potential to integrate renewable energy systems to satisfy various demands and improve energy efficiency. Solar energy is a primary renewable energy resource that can be harnessed in different ways to provide electricity, heating, and cooling in building applications. In this study, a solar–ground-source heat pump system was designed and established in a nearly zero-energy building. The system’s performance was presented, and its control strategy was optimised. To evaluate and assess the operation of the solar energy system, an experimental setup was built, and the experiment was divided into two periods, taking into account the weather conditions. In the first experimental period, different parameters of the heating system were tested and evaluated. In this regard, the variation trends of the heat pump unit’s coefficient of performance, the system coefficient of performance, the collector start-up temperature difference, and the heat pump setting temperature were analysed under different parameter combinations. On this basis, the optimal operating parameters were identified for different heating periods. In the second period, the optimal operating parameters identified were used to carry out heating experiments. The results highlighted that the adoption of the preferred operating parameters increases the percentage of direct solar energy supply by 2.0%. Additionally, the system coefficient of performance increases by 8.9%, the unit coefficient of performance increases by 6.7%, the carbon emissions are reduced by 4.18 tonnes, the SO2 emissions are reduced by 0.143 tonnes, and the dust emissions are reduced by 0.1 tonnes. The findings of this study can provide useful data and a guiding reference for optimising and promoting the implementation of renewable-energy-driven heating systems for nearly zero-energy buildings in severe cold regions.

“…Sustainable construction issues are the subject of many scientific publications, including, among others, [8,9]. A case study of the environmental impact of investment projects is characterised, among others, in [10,11]. Most attention has been paid to the energy efficiency of buildings relating to their use phases and over the entire life cycle of buildings [12][13][14], as well as the energy performance of buildings with different material and functional solutions [15,16].…”

Due to the favourable pro-environmental properties of timber, including the origin of the raw material from renewable sources, ease of reuse, negative carbon footprint, low specific weight, possibility of prefabrication, etc., there is increasing interest in the use of timber in construction. This paper takes a closer look at the new uses of timber as a load-bearing structure for high and high-rise buildings. Cases described in the literature concerning this type of building with residential and public functions erected worldwide were analysed. The first buildings of this type were put into use in 2009. The aim of this paper is to show new possibilities and to extend the use of timber as a load-bearing structure of high and high-rise buildings previously made of reinforced concrete or steel. The scope of the analysis includes two postulates of sustainable construction, directly related to the above-mentioned goals: limiting interference in the natural areas of cities through efficient use of building plots for high or high-rise buildings and the use of renewable materials—timber—for the load-bearing structure of buildings. A research method based on a case study was used. Conclusions were made on the pro-environmental spatial–functional and material–structural design of these high and high-rise buildings.
