Overview of MECcheck

The MECcheck system of code compliance documentation of options is designed to make it fast and easy for designers and builders to determine whether a new home’s design meets the requirements of the Model Energy Code (MEC). MECcheck also simplifies compliance determinations for building officials and plan checkers.

The MECcheck system offers three simple ways to demonstrate compliance with the MEC:

The prescriptive approach, the simplest of the three approaches, allows builders or designers to select from various combinations of energy conservation measures based on "climate zone" location. Each combination or "package" specifies insulation levels, glazing areas, glazing U-values (thermal performance), and sometimes heating and cooling equipment efficiency. By locating the correct climate zone and looking up the appropriate table of packages, builders and officials can ensure the project meets one of the packages listed for that zone.

The trade-off worksheet approach enables builders to vary insulation levels in the ceiling, wall, floor, basement wall, slab-edge and crawl space; glazing and door areas; and glazing and door U-values. Based on the proposed plans and specifications, the builder enters simple information on a MECcheck worksheet then hand-calculates a total "UA-value" for the project. By comparing the project's UA-value to the value required for the climate zone, the builder can determine if the project passes the MEC requirements. If the project does not pass, the builder can use the worksheet to examine a different combination of insulation levels, window or door products and areas for compliance. The worksheet is suitable for use during the plan check and field inspection phases of the project.

The MECcheck software program does the same calculations as the trade-off worksheet but automates the procedure using an DOS based PC. Special features allow builders to trade off heating and air conditioning equipment efficiency, as well as windows and insulation. The software generates a report that is suitable for plan checking and field inspection.
