Building Energy Modeling

REM Rate: EAM uses software created by Architectural Energy Corporation called REM Rate to create computer models. This software can be used to model single family houses and low rise multifamily structures. The models are constructed using the proposed or as-built architectural plans and specifications. From this model we can give you the following information:

  • Generate home energy ratings in accordance with RESNET(Residential Energy Services Network) Standards
  • Energy loads, consumptions and costs
  • Heating and cooling mechanical equipment sizing
  • Energy efficient mortgage report
  • Energy code compliance (ASHRAE and IECC)
  • Utility bill analysis for existing homes
  • Improvement analysis for existing homes
  • Design optimization for new homes
  • Energy Star Home analysis
  • EPACT tax credit certification

There are two ways this can be done, either through a field takeoff for already existing homes, or based off of design plans for new construction.

Field Takeoff: A field inspector will visit the site of the home, inspect the inside and out of the house.  The inspector will take measurements of the home and note the location of windows, doors, skylights and the overall layout to later input into the modeling software.  While inspecting the home he will be looking at everything in the home that uses electricity and can affect electricity use. The windows, insulation in the walls and attic, lighting, dishwasher, refrigerator, clothes washer, clothes dryer, and doors will all be accounted for in the modeling.  Once the field takeoff is completed all the information will be entered into REM Rate. Once the information is entered we can use the software to perform different analysis.

Plan Takeoff: Once the plans are received, a trained HERS rater will take a set of plans and input the design information directly into the REM Rate software.  We will then be able to input specifications for insulation values, window values, mechanical equipment, lighting, dishwasher, refrigerator, clothes washer, clothes dryer, and doors.  We can then run all of our analysis to help you decide which products you would like to use, and which ones will benefit you the most.

eQuest: For the purposes of modeling high rise and commercial structures EAM uses software called eQuest. This software is based off of the modeling requirements of ASHRAE 90.1 Appendix G. This standard is specifically designed to analyze the performance of these building types beyond code requirements.
The ASHRAE 90.1 energy standard involves comparing all proposed or as built building systems to a minimum baseline.  Areas covered include:

  • Building Envelope
  • Heating, Ventilating and Air Conditioning
  • Service Water Heating
  • Power
  • Lighting
  • Specialized Equipment

This modeling is required for a variety of programs including:

  • Energy Star Multifamily High-Rise
  • LEED for Homes Multifamily Mid-Rise
  • LEED for New Construction
  • Pay for Performance Programs for Commercial Buildings

EAM Associates has over a decade of experience modeling homes and other types of structures.  In this time we have modeled over 10,000 homes and other buildings. Our models use the latest software and regularly attend educational seminars to ensure the most accurate modeling possible.
