Curtain wall is the outer wall of the building, not load-bearing, hanging up like a curtain, so also known as the hanging wall, is a modern large and high-rise building commonly used with decorative effects of lightweight walls. It is composed of a structural frame and inlaid panels, and does not bear the load and effect of the main structure.
The mainland building curtain wall industry has experienced decades of development, and there have been major changes in material varieties, material properties, construction technology and so on:
1. Lighter and thinner plates and structures (natural stone thickness 25mm, new materials up to 1mm);
2. More varieties and richer colors of plates (there are nearly 60 kinds of plates such as stone, ceramic plates, glass-ceramic, high-pressure laminates, cement filament panels, glass, inorganic fiberglass, clay plates, metal plates, etc.) for external walls);
3. Higher safety performance;
4. More flexible, convenient and fast construction technology;
5. Higher waterproof performance, prolonging the life of the curtain wall (from closed curtain wall to open curtain wall);
6. Environmental protection and energy saving.
In recent years, with the promotion of energy conservation and emission reduction policies, building energy conservation has become one of the goals of the current development of the construction industry. How to integrate environmentally friendly materials and processes into the design and construction of the curtain wall is the key to the current curtain wall design.
At present, in the curtain wall project, in addition to the application of green environmental protection materials, bim, computer, Internet of Things and other technologies can also be applied, by improving the thermal insulation, heat insulation, sound insulation and other functions of the curtain wall, reducing the comprehensive energy consumption of the building and achieving the purpose of energy conservation and environmental protection.
In the design stage, the building curtain wall can be designed using the multi-professional architectural design BIM software OpenBuildlings Designer. OpenBuildlings Designer can design, build, analyze and visualize buildings of any size, form and complexity, as well as perform height, daylight exposure, shadow analysis and energy analysis of buildings.
Below, let's take a look at the specific features of OpenBuildlings Designer and what advantages there are for curtain wall BIM design:
1. Architecture
- Design buildings and structures with integrated architectural and industry-leading freeform modeling tools and capabilities;
- Create realistic single and hyperbolic planes, solids and building equipment;
- Create harmonized architectural documents (plans, sections, elevations, details, and reinforcement tables) directly from the model;
- Take advantage of bentley GenerativeComponents' computational design capabilities;
- Evaluate and simulate energy efficiency early in the design process;
- Calculate peak loads, annual energy usage, energy consumption, carbon emissions, and fuel costs with integrated conceptual energy analysis.
2. Structure
- Model steel, concrete, and timber structures, including walls, foundations, columns, and other structural components
- Generate floor plans, frame layouts, sections and elevations, as well as volume and weight plans
- Combined with detailing applications, including Bentley's ProStructures
- Leverage Bentley's RAM, STAAD, and ProStructures for structural analysis and design
- Fire treatment for steel structures
Structural expertise and analysis software are mutually directed
3. Mechanical
- Modeling fully parametric HVAC, plumbing, and plumbing systems;
- Correctly calculate pipe sizes based on airflow, flow rate and friction rate, either manually or with automatic line sizing tools;
- Create and configure HVAC units using AHU Builder's standard modules;
- Define automatically placed components while routing diagrams for HVAC and piping systems;
- Dynamic routing of the system by applying slopes or as a follow-up process;
- Export to Autodesk Fabrication CAMduct 2013 and Trimble Vulcan for use in the manufacturing process.

5. Unrestricted environment
- Integrate information from 3D models, including: hypermodel modeling drawings, images, documents, media, web links, and more
- Create virtually any geometry using the Comprehensive Modeling toolset
- Leverage specific specialized information and associated parametric modeling tools
- Create buildings of virtually any form, size, and geometric complexity
- Define capture rules for design intents, dimensional constraints, assembly relationships, and more items
6. Building performance
- Use computational design tools to model, simulate, and explore a variety of what-if scenarios
- Visualize height, slope, daylight exposure, and shadow analysis
- Create realistic model visualizations with support for multi-point automated measurements, photorealistic materials, lighting libraries, distributed network rendering, keyframes, and time-based animation tools
- Facilitate conceptual energy analysis by analyzing spatial models
Hypermodel modeling presents design information in the context of 3D model space
7. Informative deliverables
- Dynamically create 2D documents directly from the inline capabilities of 3D models
- Create accurate 2D and 3D drawings
- Get reliable design and product standards management
- Apply sites, projects, enterprises and international standards throughout the design and documentation process
- Review and share model and document markup
- Edit in-place and bidirectional editing in Excel to easily manage and sort your data
Software Details: What does this multi-discipline architectural design software do, and why does everyone love to use it to model?
The curtain wall is a transitional layer from indoor space to outdoor space, which is the basis for reflecting the appearance of architectural design and conveying the concept of architectural design. It can be said that the success or failure of curtain wall design directly affects the success or failure of architectural design.
Therefore, we should pay attention to the design of curtain wall, while following the design concept of energy saving and environmental protection, conveying a beautiful architectural appearance.
