Computer Aided Drafting (CAD) - Autodesk AutoCAD MEP

On typical projects, ECS utilizes the AutoCAD MEP, the de facto industry standard for creation of MEP construction documents. We typically utilize the most current version of AutoCAD. We have the capability to work with Architects and other team members with all previous AutoCAD versions, and can save our files to any previous format as needed.

Building Information Modeling (BIM) - Autodesk Revit MEP

Parkland College - Fine & Applied Arts

Just as Computer Aided Drafting (CAD) programs transformed the creation of construction documents a generation ago, Building Information Modeling (BIM) is poised to create a similar leap forward in building design and construction. We are actively utilizing AutoDesk Revit MEP on select projects which are looking to utilize the benefits of BIM.

With CAD programs like AutoCAD, elements like lines and arcs are used to symbolize an object. With BIM, virtually every item is a "smart" item, designed to accurately model its real world counterpart. Ducts know they are ducts, pipes know they are pipes. Further, each item knows the properties of the item it is modeled after. For example, a return air grille will know the airflow, pressure drop, size, material, etc. This allows for more intelligent designs, and can help minimize errors.

Another advantage to BIM is everything is modeled in 3D. If the architect, Structural Engineer, and MEP Engineer are all utilizing Revit, it is much easier to see where conflicts could occur between pipes, ducts, beams, high ceilings, etc. By catching more of these issues in design, there should be less spatial problems that occur during construction. Because dealing with these types of conflicts during construction can impact the schedule and result in change orders, utilizing BIM can save both time and money during the construction period.

We can utilize any recent version of Revit on our projects, and will match whatever version the Architect plans to use. Typically this will be the most recent version released by AutoDesk at the time the project kicks off.

Energy Modeling - Trane Trace 700

According to the Environmental Protection Agency (EPA), buildings in the United States account for 36 percent of the total energy use, and 65% of electric power consumption. With energy costs rising substantially over the last 10-15 years, there has been renewed interest for building owners to minimize energy usage and energy cost in their buildings. We currently utilize Trane Trace 700 for our Energy Modeling needs.

Energy Model - Sample Results

While there are several uses for energy modeling, the most common use currently is for LEED Certification. Under the current version of LEED, energy and atmosphere prerequisite 2 and credit 1 allow the design engineer to complete a whole building energy simulation. This involves comparing a model of the actual (proposed) building to a fictitious minimally compliant (baseline) building. ASHRAE 90.1-2007 Appendix G lays out the requirements for the baseline building, as well as what can or cannot be accounted for in both the proposed and baseline buildings. Once each building is properly modeled, the software can use local utility rates and historical weather data to calculate the anticipated energy usage for all 8,760 hours in a year. The end result is showing the amount of energy and cost the proposed building will save over the baseline building.

Another usage for energy modeling is doing a life-cycle cost analysis to compare different HVAC system types. In general, more efficient building systems cost more up-front, but save money in operational energy costs over time. After modeling the building components, the software can take into account other factors such as your utility's energy rates, initial equipment costs, depreciation, interest rates if loans are used to finance the project, etc. In the end, you can get a length of time it will take a more efficient system to payback, which should help the owner decide if paying an additional cost up-front is worthwhile.
