How BIM Helps in Optimizing HVAC Operation during Building Process?

What is HVAC? The main parts of the HVAC system are heating, ventilation & an air-conditioning unit.

Modern HVAC systems also include air filtration & cleaning element.

HVAC system removes contaminants in the air & conditions indoor air either cooling it or heating it to provide comfort.

HVAC in Building Sector HVAC in the building sector involves a lot of manpower from designing, operation & maintenance at various stages like the system design, load estimate, coordination, scheduling, energy simulation and for facility operations & maintenance.

The diverse stages entail different expertise for executing the activities, leading to a lot of coordination problems.

Why use BIM for HVAC in Building?

Using BIM at the pre-construction stage of the project facilitates engineers & designers to make improved decisions.

All activities associated with project completion can be made easily with 2D, 3D, 4D, 5D, 6D & 7D BIM in a single module.

The BIM-enabled solution helps to obtain energy conservation, maintenance & operation of the HVAC system.

How BIM Helps HVAC Operation during Building Process?

Multidisciplinary Collaboration with Stakeholders Operation & Maintenance with 7D BIM

Heat Load Estimation with 2D BIM

Thermal Performance of the Building with 6D BIM

360 Degree Visualization with 3D BIM

Accurate Cost Estimation with 5D BIM

Construction Sequencing with 4D BIM Model

Multidisciplinary Collaboration with Stakeholders BIM helps in pre-planning the mechanical HVAC process and comprehending design data, by providing information along with visuals in a common data environment.

To analyze design & showcase information on multi-dimensional aspects, the BIM model shows all the necessary dimensions from the conceptual stage of the design to operations & maintenance.

The design of an HVAC made in CAD can be imported in Revit BIM, identifying different dimensions concerning the design.

Heat Load Estimation with 2D BIM

BIM acts as a single point of reference for information & operational activities having manifold dimensions, wherein the 2nd Dimension gives the provision for making heat load assessments, duct sizing, pipe sizing, & pipe design.

Heat load calculations can be executed comprehensively with BIM with specific building properties like the floors, walls, ceiling, slab, building typology, location & activity in the building, lighting & equipment load, and the total number of people working.

BIM can automatically take the temperature of the dry & wet bulb and humidity by specifying the building location.

BIM provides the duct sizing as per the calculated CFM & FPM, by entering the value of FPM and mechanically calculating frictional losses in the duct & varying FPM in the branch duct and providing the size of the branch duct.

360 Degree Visualization with 3D BIM All engineering components of the buildings along with the structural & architectural ones can be visualized with BIM in 360 degrees in a different spectrum like the wireframe & rendered.

One can get the walkthrough of the entire building along with the Mechanical (HVAC), Plumbing, Electrical, Structural & Architectural components for detecting building clashes with the services.

The BIM model can be imported to the NavisWorks - another plug-in for Revit to perform clash detection & generate clash report for the entire building at once.

Complete HVAC design of a building through BIM helps to simplify the visual understanding of the duct network & its crucial components.

Construction Sequencing with 4D BIM Construction scheduling with 4D BIM facilitates in estimating the time for the installation of AC service.

BIM can easily calculate the non-working days automatically based on calendar days.

The report can be plugged-in in NavisWorks & the work schedule to be executed can be prepared.

Accurate Cost Estimation with 5D BIM

BIM model can store a lot of information for execution but the most essential one is budgeting.

To estimate the project budget, the 5D BIM cost estimation has to be made in an accurate way for the selected materials & products.

Generates the cost of desired building system for the piping & ducting.

Thermal Performance of the Building with 6D BIM

6th dimension presents data about the thermal performance of the building.

Reduces energy consumption, leading to substantial savings in the long run, gauging the HVAC system in terms of thermal comfort & indoor air quality.

Operation & Maintenance with 7D BIM BIM Model plays a vital role in maintaining HVAC system of the building using ARCHIBUS & Autodesk technology.

Through ARCHIBUS-Revit integration, one can maintain & retrieve information about HVAC with electrical components, like electrical circuits, panels, lighting, control systems & receptacles.

ARCHIBUS creates a comprehensive electrical inventory of the HVAC systems of the facility with predefined module standards with key information like the Model number, heat load, power requirements & vendor information.

One can check the circuit & panel loads and calculate the floor, building, and room from the built-in report system.

Further, overloaded circuits & other glitches can be prevented during operation.

Mapping HVAC Parameters with Revit BIM Model

Revit BIM model contains a wide array of equipment from categories like mechanical, electrical & more.

Individual equipment asset contains a substantial amount of parametric data built in system.

Revit parameters can be mapped to ARCHIBUS fields.

The process can be executed by a BIM specialist ahead of time in a planned way to capture FM appropriate data & ensure the proper use of the system.
