“…According to the China Statistical Yearbook, in 2020, stock of China's rural residential buildings reached 26.6 billion m 2 , which is the equivalent of constructing an entire New York City every month for over three decades [116]. Besides, the floor area per capita in rural residential buildings increased from 24.8 m 2 in 2000 to 47.3 m 2 in 2018 [123].With the implementation of the rural revitalization plan issued by the Chinese government [124], the ECCE of rural residential buildings will keep the increase to meet the demand of rural household and also to obtain a goal of thermal comfort in the future [125][126][127][128][129]. Since research on the CPCN of rural residential buildings is scarce at present, it will become necessary in the future.…”

Due to large energy consumption and carbon emissions (ECCE) in the building sector, there is huge potential for carbon emission reduction, and this will strongly influence peak carbon emissions and carbon neutrality in the future. To get a better sense of the current research situation and future trends and to provide a valuable reference and guidance for subsequent research, this study presents a summary of carbon peak and carbon neutrality (CPCN) in buildings using a bibliometric approach. Three areas are addressed in the review through the analysis of 364 articles published from 1990–2021: (1) Which countries, institutions, and individuals have conducted extensive and in-depth research on CPCN in buildings, and what is the status quo of their collaboration and contributions? (2) What subjects and topics have aroused wide interest and enthusiasm among scholars, and what are their time trajectories? (3) What journals and authors have grabbed the attention of many scholars, and what are the research directions related to them? Moreover, we propose future research directions. Filling these gaps will enrich the research body of CPCN and overcome current limitations by developing more methods and exploring other practical applications.

“…In the last two decades, many energy-efficient solutions have been analyzed to improve the energy performance of the building envelope by adding additional external insulation layers, responsive facade elements, or a second-skin layer [17][18][19][20][21][22][23][24]. There are two main approaches to improving the energy efficiency of buildings: (i) active or (ii) passive refurbishments [25]. The active approach consists of applying more efficient Heating, Ventilation and Air Conditioning (HVAC) systems and/or replacing obsolete and highly energy-intensive appliances (old models of natural gas-fired boiler, electric heat pump, lighting system, etc.)…”

“…The active approach consists of applying more efficient Heating, Ventilation and Air Conditioning (HVAC) systems and/or replacing obsolete and highly energy-intensive appliances (old models of natural gas-fired boiler, electric heat pump, lighting system, etc.) installed in the building, thus reducing its overall energy consumption [25]. The other way to improve a building's energy efficiency is passive refurbishment, which consists of a retrofit action that reduces the energy lost through the building envelope, improving its thermal resistance and reducing the energy demand [25].…”

In addition, passive retrofit actions are usually less invasive, allowing for renovations without changing the structure of historical buildings [26].…”

Passive Strategies for Building Retrofitting: Performances Analysis and Incentive Policies for the Iranian Scenario

et al. 2022

View full text Add to dashboard Cite

A large amount of the Iranian energy demand is related to the building sector, mainly due to its obsolescence. In this paper, a second-skin system has been implemented as a retrofit action for an office building, evaluating the effect of a tensile material as second-skin in terms of primary energy saving, carbon dioxide equivalent emissions, and simple payback period. The analysis was carried out through numerical simulations across a whole year and for four Iranian cities (Tabriz, Teheran, Yazd, and Bandar Abbas) in four different climates (cold, temperate, hot-dry, and hot-wet), and with the building aligned at either north-south or east-west. Moreover, an economic analysis was carried out suggesting different incentive policies to promote building energy refurbishment. The simulation results highlighted a favorable orientation for buildings in Iran, suggesting a guideline for new constructions. Indeed, the best results were achieved for an east-west orientation of the building (up to a primary energy saving of 13.6% and reduction of carbon dioxide equivalent emissions of 45.5 MgCO2,eq, in Yazd), with a decrease of the annual specific total (cooling and thermal) energy demand of 37.9 kWh/m2/year. The simple payback period values were also lower in the east-west orientation than the north-south one.

“…In the study of Kong et al [12], it was found that enhancing the thermal insulation of the building envelope could maintain indoor thermal comfort with relative lower supply water temperature compared to insufficient insulated building envelope, thus the energy efficiency of the air source heat pump could be improved. Hu et al [13] conducted research on the energy-saving retrofit of a rural building of Shandong and analyzed the retrofit plan of the envelope insulation based on the cost-effectiveness. Cao et al [14] proposed a retrofit solution for a farmhouse building in Anhui Province, and obtained a building retrofit solution from the perspectives of thermal comfort, energy saving rate and cost.…”

Theoretical Study on the Relationship of Building Thermal Insulation with Indoor Thermal Comfort Based on APMV Index and Energy Consumption of Rural Residential Buildings

et al. 2021

In the field investigation of rural dwellings, it was found that thermal feelings are significantly different with varied envelopes even under the same indoor air temperature, and this paper explores the phenomenon in simulation. Based on building thermal investigations in several villages of North China, a typical energy and environment simulation model for rural residences was developed using DeST, and the hourly parameters of temperature and humidity were used to calculate the adaptive thermal comfort (APMV) of the rooms. The results show that the main reason for the different thermal comfort at the same air temperature is the large difference in the inner surface temperature. By adjusting the insulation thickness of the envelope structure, the relationship between it and the APMV value is obtained. By adjusting the insulation thickness of the enclosure structure and getting the correlation between it and the APMV value, it is obtained that when the heat transfer coefficient of the enclosure structure meets 0.5 W/ (m2−K), the indoors can be in thermal comfort. This paper considers that the indoor air temperature cannot represent the APMV to evaluate the indoor thermal comfort, and the APMV value should be used to evaluate the thermal comfort of the renovated building and calculate the corresponding energy saving rate.
