Energy conservation measures can not only improve energy efficiency; it can also enhance microgrid resilience. This paper aims at investigating energy conservation in a small microgrid, using a new hospital in Riyadh city as a case study, to satisfy the Saudi Building Code (SBC part 601) requirement of energy conservation as the first case. The sec...

... is unrealistic to compare incandescent lighting fixtures with CFL and LED because outdated lighting technology consumes a lot of power and has a low lifespan, but it is useful for the purpose of comparison to show that LED makes a difference in terms of energy saving and lifespan compared to the CFL. As shown in Table 1 and Figure 11, using LED instead of CFL lighting fixtures results in an energy saving of up to 28%. Therefore, highly efficient lighting fixtures may assist in noticeable energy savings. ...Context 2

Building materials selection is a critical process affected by many complicated factors. Due to the specific function of elements, alternatives to materials must be appropriately chosen as they differ in quality, performance, and cost. Implementing a Value Engineering (VE) process is challenging as it requires effort and several workshops. us, this...

Factors such as the rapid depletion of natural resources and environmental pollution enable us to better understand the importance of the concept of sustainability today. With the introduction of the concept of sustainability into the construction sector, the design of buildings according to the environmentally friendly "Green Building" approach has come to the forefront, and various certification systems have been developed. Due to these certification systems, various building materials are required to be used in buildings. However, since there are many materials on the market, it is a problem as to which of these materials should we prefer according to the green building criteria. Although there are various approaches in this regard, the value engineering method is an ideal method because it takes into account both the criteria that the materials must meet as well as their costs. Value Engineering is the teamwork carried out to analyze the building properties, systems, equipment, and material selections, while considering the costs, in order to perform the necessary performance, quality, reliability, and basic functions. In this article, a method on how to choose a value-based, sustainable material was proposed, and as a case study, a product that can be used as an exterior cladding material of a building using LEED criteria, which is used for providing certification for sustainable green buildings, was selected. Initially, a value engineering team was formed. This team determined the qualities that the product should have based on LEED criteria and the eight different material alternatives that can meet these qualities. Subsequently, value analysis was conducted, and the highest value exterior coating material was determined.
... After the design is completed, the Robot Structural Analysis Professional finite element structural analysis software can be used to perform structural stress analysis on the concrete and steel structures in the Revit model to verify the rationality of the structural design. Before the start of the construction phase, Navisworks can be used to check the collision of the Revit model, carry out construction simulation, predict various problems that may occur in the construction process in advance, and eliminate the hidden engineering problems often encountered by the owner in the design and construction phases [19][20][21]. Overall, Autodesk's suite of software for architectural engineering enables high-quality and highperformance architectural design, optimizing projects using integrated analysis, generative design, and visualization and simulation tools. It can maximize the constructability and coordination of the project, and improve the predictability during the construction process of the project site. ...
Rebar engineering in the construction industry lacks effective technical means and has a high processing cost and high waste rate. Under the background of intelligent construction, the centralized processing mode of steel bars in prefabricated factories realizes the automatic processing of steel bars and improves the processing efficiency of steel bars. Using the C# programming language, combined with Revit secondary development technology, the automatic generation of the rebar model and the automatic export of rebar drawing are realized, which saves time for the designers to build the model. The calculation method of the cutting length of the steel bar is analyzed in this paper, which can be used as a reference for the subsequent optimization research of steel bar cutting. The assembly position information of the steel bar was introduced into an Excel table to help realize the automatic assembly of the steel bar cage and the intelligent construction of the steel bar. Combined with mixed reality technology, project personnel can interact with the reinforced BIM model through the mixed reality device Hololens2 to guide construction remotely.
Healthcare facilities play a key role in responding United Nations goals, such as sustainability, health and welling. The outbreak of the COVID-19 epidemic has driven much attention to expanding healthcare capacity through advanced digital technologies, such as Building Information Modelling (BIM). Nevertheless, a systematic review of research achievements is lacking. This research uses bibliometric and systemic literature review methods to investigate BIM applications in Healthcare Design and Construction (HDC). The bibliometric investigation focuses on country, journal co-citation, and keyword clustering analyses. The systematic review classifies application domains, BIM actions, and other digital technologies accompanying BIM. Finally, 17 major BIM actions are summarized for six major domains, including operability, resilience, collaboration, sustainability and constructability. This study reveals that the outbreak of COVID-19 has greatly stimulated the academic interest in digital technologies for HDC, and there is geographical uniqueness highly relevant to local government policies and national healthcare services. However, related research is still in a relatively preliminary stage.
