Free Technology Preview Offered for AutoCAD MEP and Revit MEP Extensions

9 Jul, 2008

Autodesk extensions were developed to help engineers design more energy-efficient building mechanical systems.

Autodesk announced today that the company is making two extensions for AutoCAD MEP and Revit MEP available to mechanical, electrical, and plumbing (MEP) engineers to design more efficient building mechanical systems. The MEP Analysis Extension, available as a free technology preview from Autodesk Labs, is a set of 25 utilities that MEP engineers can use to better understand how a building system will perform before it's built, ultimately helping MEP engineers reduce energy costs and environmental impact while improving the performance of building systems. The HVAC Load Calculation Extension, available for Autodesk Subscription customers of AutoCAD MEP and Revit MEP, performs peak cooling and heating load analysis for commercial buildings so that engineers can properly size HVAC equipment. Both extensions can function as stand-alone applications, but also work in conjunction with both AutoCAD MEP and Revit MEP.

The MEP Analysis Extension calculates rule-of-thumb cooling and heating loads for commercial and residential buildings, calculates total R-Values for walls and roofs, determines psychrometric properties of air, and more. Running these types of calculations through the MEP Analysis Extension can help MEP engineers reduce error and waste, potentially saving energy costs, the company states. The MEP Analysis Extension also contains utilities for sizing duct work, piping, and HVAC systems, helping engineers and architects identify the most appropriate building equipment early in the design cycle.

The following utilities are included in the MEP Analysis Extension:

  • Metric to English units converter
  • single-state psychrometric calculations
  • mixed-air psychrometric calculations
  • duct sizing calculations
  • ASHRAE duct fitting pressure loss calculations
  • general pipe sizing
  • hot/chilled water pipe sizing
  • steam pipe sizing
  • low-pressure gas pipe sizing
  • high-pressure gas pipe sizing
  • refrigerant pipe sizing
  • fan cost analysis
  • fan curve analysis
  • pump curve analysis
  • rule-of-thumb commercial HVAC load calculations
  • simple residential/light commercial HVAC load calculations
  • swimming pool heating calculations
  • u-value calculations
  • gbXML parser
  • wire sizing utility
  • glass moisture condensation
  • life cycle cost analysis
  • a super calculator for complex equations
  • manage HVAC equipment lists
  • manage climatic weather data

The HVAC Load Calculation Extension is a comprehensive HVAC (heating, ventilation, and air-conditioning) load calculation software tool that determines building peak cooling and heating loads based upon current calculation techniques from ASHRAE. Using the results from the software, engineers can properly size cooling and heating equipment without oversizing such equipment, which often results in wasted energy. The Load Calculation Extension works as a stand-alone application, but also integrates easily with BIM modelers such as Revit MEP.

The MEP Analysis Extension is available as a free technology preview from Autodesk Labs. Visitors to Autodesk Labs are encouraged to experiment with inventive new tools and provide feedback to the Autodesk team. The HVAC Load Calculation Extension is available to customers of AutoCAD MEP 2009 and Revit MEP 2009 on Autodesk Subscription and is subject to Autodesk Subscription terms and conditions. The extension is currently available in English only, but will operate with all language versions of AutoCAD MEP 2009 and Revit MEP 2009 software.
