The existing building reconstruction methods exist after three-dimensional building modeling information is not complete, and the wall insulation performance improvement effect is not obvious. Therefore, a reconstruction method of existing residential buildings based on 3D simulation is proposed. This paper analyzes the present situation of energy consumption of existing residential buildings, analyzes the fuzziness characteristic in the process of testing the thermal performance of existing residential buildings by the method of spatially distributed fusion and feature extraction, uses the fuzzy equilibrium scheduling method to decompose the fuzziness characteristic scale of the thermal performance of the thermal insulation of existing residential buildings, and optimizes the design of the thermal performance of the thermal insulation transformation of existing residential buildings. The 3D simulation software is a 3D modeling tool named 3DS Max. The real-time simulation software Unity3D engine is used to reconstruct the building scene and complete the reconstruction of existing residential buildings. The experimental results show that the information integrity of the building model reconstructed by 3D simulation technique is nearly 100%, and the insulation performance of the building wall is better.

“…Yang and Zhang [26] categorized outpatient buildings into centralized, corridor, and courtyard forms and analyzed suitable building forms and orientations for five climate zones with low energy consumption. Deng et al [32] analyzed four types of university library buildings: point, slab, block, and comb, and summarized the appropriate low-energy building forms for four different climate zones. Premrov et al [33] analyzed the energy demand of square, rectangular, L-shaped, T-shaped, and U-shaped cabins in three different climates and showed that the shape factor only had a significant impact on energy consumption in cold regions with low solar energy.…”

“…The aim of this study is to evaluate the carbon-saving potential of different forms of gymnasiums with integrated BIPV systems on their roofs, taking into account the differences in energy consumption and PV power generation due to different building forms based on the different climatic conditions in China. The Chinese national standard "Thermal Design Code for Civil Building" (GB 50176-2016) [46] divides China into five primary building thermal design zones, and many building performance studies are based on this climate zone division [26,32,47]. However, this study also needs to focus on the impact of solar energy resources on PV power generation, so this study will use a new climate zone model that was reformulated by Sun [48] based on the consideration of climatic factors and solar radiation levels, which consists of seven climate zones: severe cold high irradiation, severe cold medium irradiation, cold high irradiation, cold and summer hot, moderate high irradiation, hot and humid cold winter, and hot and high humid zones, which has been applied in a number of studies on PV systems for buildings in China [49,50].…”

In this study, the influence of the gymnasium building form on energy consumption and photovoltaic (PV) potential was investigated to address its high energy consumption and carbon emissions issues. Five cities in different climate zones in China (Harbin, Beijing, Shanghai, Guangzhou, and Kunming) were selected as case study environments to simulate and calculate the energy use intensity (EUI), photovoltaic power generation potential (PVPG), and CO2 emission (CE) indicators for 10 typical gymnasium building forms, while also assessing the impact of building orientation. This study found that changes in gymnasium building orientation can cause a 0.5–2.5% difference in EUI under the five climatic conditions, whereas changes in building form can cause a 1.9–6.4% difference in EUI. After integrating a building-integrated photovoltaic (BIPV) system on the roof, changes in building orientation and form can lead to a 0–14.4% and 7.6–11.1% difference in PVPG and a 7.8–68.1% and 8.7–72.0% difference in CE. The results demonstrate that both the choice of form and orientation contribute to a reduction in carbon emissions from BIPV gymnasiums, with the rational choice of form having a higher potential for carbon savings than orientation. These research findings can guide the initial selection of gymnasium designs to pursue low-carbon goals.

“…In particular, in hot and humid climates, the main energy consumers are air-conditioning (AC) and space-dehumidifying systems, which are utilized to provide a comfortable environment in buildings [7]. For instance, educational buildings and academic libraries with relatively straightforward functions consume a substantial amount of fossil fuel energy due to there being several users at different times of the day [8]. Moreover, more than 60% of the energy consumed in educational buildings belongs to the cooling, heating, and lighting systems.…”

The indoor environmental quality of a library greatly affects the comfort and productivity of its users while preserving the materials. Despite the high energy consumption of HVACs in libraries, achieving acceptable thermal conditions, acceptable acoustics, and sufficient daylight levels for users remains a challenge. There are limited studies on the IEQ of educational buildings, especially regarding the current situation of libraries. It is important to conduct further studies to define design guidelines promoting indoor environmental conditions. The main objectives of this study were to investigate the IEQ of Zaba Library at the University of Malaya and to recommend retrofitting strategies. The IEQ parameters in Nadir’s room, which houses special collections, and in the library hall were assessed using a full-scale measurement, with eight HOBO data loggers and sensors deployed in various locations to monitor IEQ. A comparison of the results with the standards revealed that Nadir’s room was unsuitable for maintaining rare collections, as the average indoor air temperature exceeded 21.2 °C, which is beyond the threshold limit. Additionally, the relative humidity ranged from 51.3% to 55.8%, which is marginally high. To provide acceptable indoor conditions, this study recommends retrofitting strategies for the exterior walls, such as using cement plaster with a low thermal conductivity. In the library hall, the reading zone was found to be thermally uncomfortable. The air velocity was below the range of 0.15 ms−1 to 0.50 ms−1 recommended by MS 1525. The average CO2 level was 479.5 ppm, with some points registering an increase of up to 588 ppm. The noise level in the library hall ranged between 43 dB(A) and 61 dB(A), while the light intensity was below 300 lux in the reading area, which is not within the acceptable range. This study suggests improvement solutions, such as implementing an air temperature between 24.5 and 26.5 °C for higher thermal comfort and increasing the window-to-wall ratio to utilize natural daylight. These findings provide insights into the design of new libraries and the renovation of existing ones, ensuring that libraries continue to serve as vibrant centers of knowledge and learning for generations to come.
