Instead of directly explaining the inputs which are required for the execution of HVAC (heating, ventilation and air-conditioning) design services, let me throw some light on what exactly HVAC systems are used for. Heating, ventilation and air-conditioning systems are utilized by building owners for obtaining thermal comfort and immensely soothing and suitable indoor air quality. HVAC design services are important part of mechanical design services wherein mechanical engineers have to make use of engineering principles such as thermodynamics, logic and reasoning and fluid mechanics etc for the development of high quality design for heating, ventilation and air conditioning systems. Mechanical engineers also have to consider the principle of heat transfer when design is created for HVAC systems. For regulating healthy indoor conditions it is important that requisite temperature is maintained, moisture and foul smells are eliminated from the room and fresh oxygen is retained, and all this can only be achieved if high-quality HVAC systems are installed in the building.

HVAC design in BIM design

What kinds of inputs are required for the execution of HVAC design services?

Using a building information model (BIM) from the beginning of a project helps engineers and designers make better decisions earlier in the process. A BIM’s 3-D graphics of buildings and systems are generated by data that can be easily changed as the project moves along. Most BIM software* links intelligent objects† together, so when a change is made to one object, parametric changes are made to any other objects that are linked. For example, if an engineer changes the airflow of a diffuser, the corresponding duct, diffuser and neck sizes automatically change.

Input needed for the execution of HVAC design services

  • The most important inputs for the execution of HVAC design services come from the side of architects.
  • Before starting the design development for heating, ventilation and air conditioning systems, mechanical engineers must be having the detailed instructions or specifications from architect’s side.
  • Architectural drawings and plans should be provided to them so that they can explicitly understand the entire architectural design, which helps them in understanding how they can design necessary HVAC systems for the building.
  • So contractors must provide the HVAC design team with accurate drawings and pictures of the building.
  • Apart from that HVAC design team should also be provided with the overall required performance capacity of heating, ventilation and air conditioning systems.
  • It’s very helpful if general contractors can provide the dimensions of different rooms to mechanical engineers; this can help a lot during design process.
  • Apart from that explicit information about the shape and size of all the doors and windows is also necessary for mechanical engineers.

So with the help of above information, HVAC design team can effectively plan how to design HVAC systems. Reference bim services india.

Autodesk ForceEffect for iOS : Interactive force diagrams

Yesterday, I installed a new (and currently free) app from Autodesk onto my iPhone, called Autodesk ForceEffect(check it out in the App Store).

With this app, you can draw a 2D schematic of beams, nodes and forces. It will allow you to quickly assess the reacting forces into a structure. The examples included with the app also show you that a photograph can be used as an underlay, to sketch on top of them, e.g. to check a structure in the field.

While the iPhone screen is quite small for my not-too-small fingers, it works quite handy: there are automatic guidelines that constrain the direction and alignment of nodes you draw. You can switch units between metric and imperial and use gestures for scaling (pinch), panning (two finger swipe) and editing (single touch). Moreover, while it is hard to sketch an exact size for a truss, you can fix the length be entering the exact value on the dimension line and this will be enforces, even when you start moving nodes around.

Click on a truss, and you get the acting forces (in color, with direction to show pressure or tension).

You can generate a report, which could be used to help you enter the exact nodes and sizes and forces in a FEA software afterwards, when you want to go a step further.

This is exactly the type of app I would have loved while being an architectural engineering student, quite some years ago. It’s intuitive, interactive and free (for the moment?). You’ll need an iPhone, iPad or iPod Touch to be able to use the software, but I wouldn’t be surprised if they will port it to other devices in the near future as well.

Top 10 Benefits of BIM

BIM Building information modeling abbreviated as BIM, is an evolved process that helps creation and management of all the information – ‘physical and functional’ pertaining to the design,construction and management of a building.

bim in india

BIM ( Building Information Modeling ) is being increasingly used for building and construction projects due to the high business value it offers. It has garnered huge popularity and acceptance across the AEC industry and is used for management of several large scale construction projects across the world. The acceptance of BIM in building and construction projects was not smooth and easy; there were lot of apprehensions across the industry. However, with proven benefits, BIM managed to gain acceptance.
Here we elaborate why…

  1. Visual access to building information:  Building Information Modeling is actually a 3D model loaded with all the information like quantity take offs, MEP design details, cost details, project schedules and many more. All this information is available in a visual format. For example – as schedule progresses, it is also possible to view the simultaneously accrued costs.
  2. Helps schedule the construction process:   The information about the construction schedules is fed into BIM and it can be visualized as a process. As the schedules i.e. the construction process progresses, the use of materials, the accrued costs, the productivity of labor etc all can be evaluated and hence projects can be planned in a better manner.
  3. Enables easy conflict resolutions:   Any kind of conflicts in the design can be easily detected in a BIM environment. This is because of the effective visualization. If the MEP design conflicts with the structural design, then this conflict can be easily viewed in BI model, when the MEP and structural information is fed into it. On detection, these clashes can be immediately addressed and mitigated.
  4. Helps manage the involved costs:   Building Information Modeling allows effective and near to accurate cost estimation at every stage of construction process. Besides all the conflicts are mitigated early on and hence, any possibility of rework or unnecessary expenditures is negated. Therefore, BIM ensures that the capital is used in the most prudent and efficient manner.
  5. Supports lean construction:   Building Information Modeling allows continuous and concurrent improvements across all the dimensions of a built environment and a construction process, in terms of design, construction, energy efficiency, maintenance and recycling. Hence utilizing the minimum resources, minimum materials, minimum labor and by adopting the best planning and management practices highest value is generated.
  6. Allows improved coordination and better management:   All the people involved in a construction project i.e. architect, builder, construction manager, MEP engineer, Structural engineer, etc; remain updated about even the smallest change in the building design through the BI model. This allows better coordination between teams and hence better management.
  7. Supports detailed documentation across the buildings lifecycle:   Building Information Modeling doubles up as detailed documentation for a building and construction project. As mentioned in the previous point, the ‘I’ in BIM is very important. The model can store all information right down to the scratch.
  8. BIM can be leveraged for sustainability   Using BIM as an integral part of the design process, the aspect of energy efficiency, waste management and water management and hence sustainability can be efficiently integrated into a building design.
  9. Repair, renovation and refurbishment becomes easy:   BIM is the most effective tool for retrofit and renovation projects. This is because of the ‘I’ in BIM. The model has all the information about the construction project, any renovation and repair work can be planned surrounding this information.
  10. Enables effective facility management:  When integrated with a computer aided maintenance management system, BIM allows effective management of a facility. After the building is built and occupied, there can still be a lot of conflicts due to the changing spatial requirements. These can be efficiently handled by using Building Information Modeling as an operations and maintenance tool.
