“…The algorithms embedded in EnergyPlus have been extensively verified in extensive literature, and most are reliable and valid. 29,30 Though some of the algorithms may need to be revised in predicting local conditions (such as the algorithms of convective heat transfer coefficients), they are considered acceptable to present the overall environment. The boundary conditions set in this study are derived from actual measurements, therefore, are valid.…”

With the advance of urbanization, energy consumption of public buildings is increasing rapidly, and it is urgent to achieve sustainable development of buildings. For public buildings, its energy-efficient envelope design is of great importance and necessity, which has been widely adopted to reduce energy consumption and CO2 emissions without sacrificing indoor thermal comfort. In this study, a progressive design approach of building envelope is proposed for energy-saving and low carbon emission. Then, the proposed method was applied in an archive building in Nanjing, China, with multiple rounds of design modifications of building envelopes through numerical simulations of building performance. The indoor temperature fluctuation, building energy consumption and CO2 emission were evaluated. Compared to the initial design, the optimized design can save 20.00%, 25.66% and 20.97% of building energy consumption in summer, winter and the entire year, respectively. Furthermore, the optimized design can reduce 20% and 25% of carbon emission in summer and winter, respectively. The progressive design method for building envelopes can significantly save energy consumption and reduce carbon emissions. In addition, it provides a reference for future green building design and application, which promotes the sustainable development of green and low-carbon buildings.

“…However, different stakeholders that participate in building-envelope renovation agree that facade upgrading with prefabricated modules also needs to be more efficient [2,[10][11][12][13][14]. There is a general need for a more automated process to achieve a safer and more effective process [15][16][17]. The renovation of building envelopes using modules has not taken off, as expected, despite the effort put forth in the research programs [18].…”

In order to reach a Zero-Energy-consuming building stock, it is necessary to insulate and add renewable energy sources on top of existing building envelopes. Off-site prefabricated modules have been used for covering building facades, but manual on-site installation procedures are still more competitive than prefabricated ones. Renovation with prefabricated modules requires high precision in order to obtain airtight and waterproof conditions. For that, an accurate installation of the anchors on top of the facade is crucial. With current techniques, this is a time-consuming operation. One of the attempts to solve the above-mentioned issue was to place the part of the anchor on top of a building facade with high tolerances and to use an interface to correct the deviations. In previous research, this concept, named Matching Kit, was validated, but improvements needed to be made to make it more competitive. In this paper, thanks to novel algorithms and the use of Point Clouds, an improved version is presented. The results show a reduction in working time and an increase in precision. With this research, the interface is closer to being used in the construction industry.

“…The requirement for mass customization is still present [9], but at present, manual processes using prefabricated modules are still more effective, affordable, and practical [10]. Therefore, significant effort is needed to improve and automate facade renovation processes using prefabricated modules [11][12][13][14].…”

Prefabricated modules are being used to renovate the building envelope. However, compared to manual methods, the design and prefabricated module’s definition is time consuming. Therefore, it is necessary to improve the efficiency of the prefabricated layout definition processes by incorporating automation and computational design. The purpose of this paper is to present a semi-automated definition of the layout of the prefabricated modules with the only input of the existing building facade being the Point Cloud. In this research, a novel step-by-step workflow was developed. More precisely, an algorithm was developed that processes the coordinates of each point of the cloud and generates the layout of the prefabricated modules. To validate the workflow and the algorithm, four facades were tested, considering two parameters: (a) working time and (b) output accuracy. According to the results, it was concluded that spending more time achieving an accurate laser data acquisition can be a good strategy to obtain the primary layout with sufficient precision.
