to read building plans and an understanding of how the energy efficiency of building features (e.g. U-factors, SHGC, R-values, SEER, etc.) are specified.
Although Micropas is a capable general purpose hourly simulation program for energy efficient residential buildings, the main use of the program is to document compliance with residential building energy codes such as the Model Energy Code and California's Title-24 Code.
Data is required describing each building thermal zone (15 maximum); opaque surfaces (walls, roofs, floors, 100 maximum); fenestration products (doors, windows, skylights, 100 maximum); thermal mass (slabs, etc., 25 maximum); HVAC equipment (heating, cooling, venting, thermostats) and water heating systems (domestic and hydronic heating).
Seven types of clearly formatted printouts are available including summary output, detailed building descriptions, HVAC sizing summary and assembly U-value calculations. For detailed oriented studies, yearly, monthly, daily and hourly table output is available including time-of-use and bin data. Annual and table outputs can be saved in delimited formats suitable for importing into other software for additional analysis and graphics. For studies including many runs, a parametric run generator and databases of run results are available.
Mature and reliable program used daily by hundreds of energy consultants in California. Good documentation and good support via toll free number. Can calculate annual energy usage and provide load (sizing) calculations at the same time. Able to manage multiple runs. Not as complex as DOE-2, not as simple minded as UA type compliance programs.
