Building engineering is a branch of engineering that deals with the design, construction, and maintenance of buildings, including their structural, electrical, mechanical, and plumbing systems. Structural engineers and MEP engineers are responsible for ensuring that buildings are safe, efficient, and comfortable for their occupants. They work closely with architects, contractors, and other construction professionals to design and implement building systems that meet the needs of their clients.

Autodesk offers several building engineering solutions that help structural and MEP engineers design and optimize building systems. For example:

• Revit: A building information modeling (BIM) software that allows users to design and model building systems, including HVAC, plumbing, electrical, and structural systems.
• AutoCAD MEP toolset: A drafting and design software specifically tailored to the needs of mechanical, electrical, and plumbing (MEP) professionals.
• Autodesk CFD: A computational fluid dynamics software that helps designers and engineers optimize the performance of HVAC and other building systems.
• Insight: A building performance analysis tool that allows users to simulate building energy use, daylighting, and thermal comfort to optimize building design and operation.
• BIM Collaborate Pro: A cloud-based collaboration platform that helps teams coordinate and manage building projects throughout the design, construction, and operations phases.

Some key disciplines within building engineering include:

• Structural engineering: These engineers are responsible for the design and analysis of the structural systems of buildings. They ensure that buildings are structurally sound and can withstand various loads and forces.
• Mechanical engineering: These engineers design heating, ventilation, and air conditioning (HVAC) systems, as well as plumbing and fire protection systems. They also ensure that these systems are energy-efficient and environmentally sustainable.
• Electrical engineering: These engineers design electrical systems, including lighting, power, and communication systems. They also ensure that these systems are safe and comply with building codes and standards.
• Plumbing engineering: These engineers specialize in designing plumbing systems for buildings and other structures. They use their knowledge of physics, mathematics, and building codes to create effective and efficient plumbing systems that provide clean water for consumption and remove wastewater and sewage.

Note that different companies or organizations may use different names for these disciplines, and there may be some overlap or variation in how these disciplines are defined. 

• Building Information Modeling (BIM) is a digital model-based technology that allows architects, engineers, and construction professionals to collaborate on a building project in a virtual environment.
• The Internet of Things (IoT) is a network of devices that can be connected to the internet and can share data and communicate with each other. In building engineering, IoT can be used to improve energy efficiency, automate building systems, and enhance occupant comfort.
• Green building practices focus on designing and constructing buildings that are environmentally sustainable, resource-efficient, and energy-efficient. This includes the use of renewable energy sources, such as solar power, as well as energy-efficient building materials and technologies.
• Virtual and augmented-reality technologies can be used in building engineering to create immersive experiences that allow stakeholders to visualize the design of a building and identify potential issues before construction begins.
• 3D printing is a process in which a three-dimensional object is created from a digital model by laying down successive layers of material. In building engineering, 3D printing can be used to create complex structural components or building modules with greater precision and efficiency.

Green or sustainable building engineering is an approach to building design, construction, and operation that aims to minimize the negative impact of buildings on the environment and human health. This is achieved by using renewable energy sources, optimizing energy efficiency, reducing water consumption, and selecting materials that have a low environmental impact.

Green building engineering also considers the social and economic impacts of building design and operation, such as occupant health and comfort, and the life cycle cost of the building.
 

Some specific features of green building engineering include:

1. Energy-efficient heating, ventilation, and air conditioning systems
2. Renewable energy sources, such as solar or wind power
3. Water-efficient fixtures and landscaping
4. Use of recycled or low-impact building materials
5. Building automation systems for optimizing energy use and occupant comfort
6. Indoor air quality control measures
7. Design for human health and wellness, such as natural daylighting and biophilic design.
8. Use of digital design practices that catch errors in the design phase, minimizing re-work and waste in construction.
9. Application of analysis tools that enable efficient use of building materials.

Overall, green building engineering seeks to reduce the impact of buildings on the environment and promote sustainable development.

Autodesk provides a range of software solutions to address various challenges in building engineering. Some of the key challenges that Autodesk software can help solve include:

• Collaboration: BIM Collaborate Pro allows multiple team members to work on a project simultaneously, streamlining collaboration and reducing the risk of errors.
• Design accuracy: With Autodesk software such as Revit, building engineers can create accurate and detailed 3D models of buildings, helping to reduce errors and ensure that the final design meets all requirements.
• Project management: BIM Collaborate Pro and Autodesk Docs can be used to manage projects from start to finish, including scheduling, resource allocation, and cost tracking.
• Sustainability: Software such as Revit and Autodesk Forma provides tools for analyzing the energy performance of buildings, allowing engineers to identify areas for improvement and design more sustainable buildings.
• Code compliance: Robot Structural Analysis Professional(Available only as part of Architecture, Engineering & Construction Collection) can help ensure that building designs comply with local building codes and regulations, reducing the risk of legal or financial penalties.

Building engineering refers to the design, construction, operation, and maintenance of buildings and their internal systems such as heating, ventilation, and air conditioning (HVAC), electrical, and plumbing systems. On the other hand, infrastructure engineering refers to the design, construction, operation, and maintenance of large-scale public works such as transportation systems (roads, bridges, airports, railways), water supply and sanitation systems, and public utilities. While both disciplines involve the design and construction of physical structures, infrastructure engineering focuses on larger-scale projects that serve a broader community, while building engineering is more focused on the individual structures themselves.

Autodesk offers several certifications for professionals in building engineering. One popular certification is the Autodesk Certified Professional: Revit for Structural Design certification, designed for professionals who use Autodesk Revit for structural engineering and design. Additionally, Autodesk offers certifications for professionals who use their software for electrical or mechanical engineering and design. These certifications include the Autodesk Certified Professional: Revit for Electrical Design certification and the Autodesk Certified Professional: Revit for Mechanical Design certification. These certifications can demonstrate a professional's proficiency with Autodesk software and can be a valuable asset in the job market.

Digital twins can be used in building engineering to create virtual replicas of physical buildings. These virtual models can then be used to simulate and test various scenarios, such as energy consumption, temperature regulation, and air quality control, to optimize building performance. By using sensors and real-time data, digital twins can also monitor and detect potential issues in the building, allowing for proactive maintenance and repairs. Digital twins can also be used in the design phase to visualize and test building designs before construction, allowing for potential issues to be identified and addressed early on.
