The BIM model can also generate professional construction drawings of buildings, structures, and equipment.

Green Building Design Based on 5G Network and Internet of Things System

An information-based and intelligent comprehensive energy consumption management system should not only collect, manage, and analyze energy consumption data but also monitor the environmental data inside the building, to manage and display the real energy consumption and internal environmental quality more effectively and reliably. In order to solve this problem, the design and construction of the front-end hardware of the energy consumption management system are proposed, mainly including the design of data acquisition node and data centralization end. The design of data acquisition node includes the selection of DSP controller, wireless communication module, and data acquisition module and the design of main circuit and peripheral circuits. The design of data centralization end includes the selection of its high-performance processor and the transplantation of Linux operating system. This paper only introduces the design and research of lighting control algorithm and applies fuzzy control algorithm to intelligent lighting. The fuzzy control system is introduced, and a fuzzy controller based on intelligent lighting is created. The fuzzy control rule table and fuzzy control query table of the intelligent lighting system are obtained through the fuzzy control algorithm. According to the basic rules of light intensity control, when the indoor light intensity is greater than the set value of light intensity, the LED lamps are turned off, so when e < 0 , the LED lamp is off and the PWM output value is 0. Therefore, when designing the fuzzy controller of intelligent lighting system, the basic domain of illumination intensity error E is 0500 , excluding the case that the indoor illumination intensity is greater than the set value of illumination intensity.

Transformation-based design method for the integration of green residential buildings and solar thermal collectors

This study investigates integrated application of solar thermal collectors (STCs), as green renewable energy, on the design of green residential buildings (GRBs). With the gradual increase of residential buildings, the use of solar thermal energy has be- come the main popularization and application mode for the integration of residential buildings and solar energy. Additionally, this study presents applicable solutions using the transformation-based design method to expand the functions of STCs through the integrated design of STCs and GRBs, thus laying a strong theoretical foundation for promoting the integrated design of solar water heaters and GRBs.

Green Building Design Concept: A Sustainable Approach

Concrete is the more widely utilized construction material on the planet earth, particularly in evolving and developing nations. Concrete was created as a stronger and more resistant building material as it was worked upon over time. Gradually, the man figured out how to create it, transport it, and utilize it more efficiently. We know that concrete is made from cement, sand, aggregate, and water. Out of these, some of them may be replaced with some other material like wheat straw ash, rice husk ash, fly ash, etc. for various purposes, mostly to utilize waste material without affecting the important properties of concrete beyond acceptable limits. This study deals with an investigation into the properties of concrete by partial replacement of sand with wheat straw ash and the addition of polypropylene fiber in it. Wheat Straw is the portion of leftovers of the wheat crop after it is harvested. In most countries, it is a waste. People burn it and cause pollution and health hazards, good strength and high performance in concrete are very much required in future construction work. It is felt that fiber dispersion in concrete is one method to improve the structural characteristics of concrete.

Application of CFD to Reduce the Cooling Load of a Building: An Alternative Approach for Green Building Design

Approximately 23 % of total CO2 emissions are attributed to the construction industry each year; in 2009, the industry produced 5.7 billion tonnes of CO2. Green building design is concerned with constructing a building in such a way that its carbon footprint is reduced throughout its life span. Lecture rooms are key components of educational institutions because they are where students spend the majority of their time. This study aims to propose a methodology to convert the existing designs of building to green buildings by optimizing the airflow. The lecture room at UET was chosen for this investigation because the air velocity distribution inside the room is not uniform due to the current design, which influences the convective heat loss from the room by creating pressure and temperature gradient. SOLIDWORKS 2021 was used to create the model of a lecture theatre. Because the majority of the rooms are naturally ventilated, a fluid dynamics analysis was performed on ANSYS Fluent 19.1 to ensure proper air ventilation. Natural airflow was improved by the addition of an extra column of windows. The total electric energy load has been computed, and the quantity of solar panels necessary to meet the demand has been recommended.

Application of Epistemic Uncertainty Analysis and Sensitivity Analysis in Green Construction Design

Building performance is often expressed according to primary energy use; however studies should also include environmental load. To mitigate the effects of increased CO2 emissions, green building designs are now increasingly popular options for stakeholders. In contrast, impacts of green design parameters, building performance assessment, and design optimization objectives are not addressed sufficiently for American infrastructure. Designing low-energy architecture to minimize carbon emissions requires thoughtful articulation of green building design alternatives. A common barrier for green building design in the U.S. is the time needed to identify and evaluate alternatives. Modeling energy consumption in buildings is essential for different applications, including building energy management and establishing baselines for sustainable building performance codes. This paper proposes a new optimization objective, which considers annual carbon emissions for multi-family construction in Florida. A multi-step sensitivity and epistemic uncertainty approach are proposed to identify the critical design parameters during the early stages of sustainable building design. Building simulation software was utilized to model green building configuration for carbon emission values, further analyzed using Monte Carlo and Morris Method sensitivity analysis techniques. The present study considered green building design alternatives as variables since carbon emission reduction potential is sensitive to these variables. Results indicate that PV panel efficiency, PV payback limit, lighting efficiency, plug load efficiency, and solar heat gain coefficient are highly influential parameters. The methodology is presented, and an example is applied to a new construction multi-family apartment design in Tallahassee, FL. This uncertainty and sensitivity analysis improved the design efficiency, while emphasizing usefulness in the green building optimization process.

Green BIM-based study on the green performance of university buildings in northern China

BackgroundEnergy-efficient university campuses will play a vital role in the development of future sustainable cities, and will be important for achieving the Chinese carbon-neutrality goals. It is, therefore, necessary to develop new decision-making tools for evaluating the sustainability of campus buildings. Since university campuses typically comprise a broad variety of building types, standardized evaluation methods and tools, such as Green BIM, are needed. Green BIM (Building Information Modeling) emphasizes the importance and role of BIM technology in the design and construction of green buildings, providing a standardized framework for the decision-making process, and methods for improving the green performance of buildings.MethodsThis study develops a method based on the Green BIM framework, using BIM architecture to analyse building performance, and the Assessment Standard for Green Building (GB/T 50378-2019) standard to establish benchmark values for evaluation, and project objectives. The method is evaluated on three examples of the most representative university buildings in northern China. The goal is to understand common denominators and differences between different types of campus buildings, in terms of green building indicators, that are important to consider in the early design stages of campus building complexes.ResultsIn this study, a library is used as a case study to demonstrate the tools for evaluating green performance. The study optimizes green performance from five aspects: surrounding environment, function layout, envelope performance and system transformation, and management measures improvement. The results show that this optimization scheme can achieve reductions of the annual loads of about 47.4%, in line with the national energy efficiency standards for public buildings. In particular, the heating load was reduced by 59.1%, and the cooling load reduced by 21.5%.ConclusionA comprehensive approach, combining the aspects of planning, building design, system design, energy management, and energy conservation planning, is required to improve the green performance of university buildings to meet the goals. In the future, it will be further necessary to perform data mining of energy consumption patterns, and continue energy retrofitting of existing buildings and energy systems, to achieve the goal of green and low-carbon campuses.

A Novel Method of BP Neural Network Based Green Building Design—The Case of Hotel Buildings in Hot Summer and Cold Winter Region of China

With the advent of the big data era, architectural design gradually tends to become more quantified and intelligent. This study proposes a novel green design method for energy-saving buildings based on a BP neural network. This study changed the traditional trial–error mode by evaluating energy consumption based on design performance parameters such as building shape, space, and interface. Instead, energy consumption quota values obtained from statistical data, as well as thermal parameters and energy system parameters in energy-saving standards, were taken as input parameters, and then the design scheme of building shape can be obtained through BP neural network technology. Based on data of 61 hotel buildings in a representative city among a hot summer and cold winter climate zone, the BP neural network model is established to control the building design variables, with 41 kgce/m2·a as its energy-saving design target. Through the energy consumption quota, the trained BP network is applied to predict the optimal architectural design parameters, including the building orientation angle, shape coefficient, window–wall ratio, etc., for twelve building typologies in an area range of 5000~60,000 m2. With recommended control thresholds of quantifiable architectural design elements obtained, this research can provide effective design decision-making suggestions for architects.
