Back in the pre-digital age, mechanical engineers go through the excruciating process of calculating the HVAC systems by paper and pens, cross-checking the hard copies of mechanical blueprints against each other, and any other inefficient scenario that you can ever think of.
Now, instead of going through all the menial tasks, our mechanical engineers can now zero in and focus on the most essential item for your building structure: optimizing the performance of the mechanical system without over-engineering.
Revit for BIM is one revolutionary software, and by all means, this is one of the useful toolsets mechanical engineers take advantage of for designing complex mechanical design plans. Such parameters can range from designing the piping and ducting systems for intent, to specifying the cooling and heating loads of your building structure.
Our expert mechanical engineers show you how you can apply these mechanical principles stage-by-stage in Revit Design:
- Perform heating and cooling loads analysis
To start, we need to prepare the building model first and input data such as location and building definition for accurate analysis on your loads. Then, we specify data for the spaces in your building structure and modify the building parameters, if need be. Each space should be assigned and verified to a zone, then properly enclosed on the boundaries. This step is critical since the analytical model will check for the enclosure once we launch the button for heating and cooling loads, and those that are not properly bounded will need to be re-modified again. Our mechanical engineers aim for efficiency on this stage as this is a must for the next step.
- Define requirements for heating and cooling loads
From the heating and cooling loads analysis above, you get a summary report on the definitive requirements for each space. As experienced engineers running Revit to its effective capacity, we examine the results, make further adjustments as needed and then re-launch the analysis until we get excellent results for your building structure. Iterative process often take time, but we do not stop until we get to your desired results.
- Select components for HVAC systems
Only when we are satisfied with the loads analysis results and report do we resume with the selection of parts for your Heating, Ventilation, and Air-Conditioning (HVAC) system. From the spaces we previously analyzed, our mechanical engineers create a schedule in Revit and formulate conditional parameters for the comparison of the required and actual airflow in each space. We utilize this space schedule for selecting the air terminals and equipment for your project. If required, we specify the ducts and fittings of your HVAC system. Using the heating and cooling loads analysis and reports we garnered previously, we load the air terminals and air handling equipment then cross-check the actual results from the planned airflow.
- Design the ducting system
Our final action for designing your HVAC systems is to create its ducting system. First, we calculate the duct sizes for correct airflow. Then, we layout the ductwork for connecting the air terminals and air handling equipment, and finally route them to supply, return and exhaust systems. Our mechanical engineers further implement testing and commissioning (T&C) measures by utilizing the system inspector in Revit for your building’s airflow verification.
