Marketmanager for windows

Introduced in late 1993, MarketManager for Windows (MMWIN) is a productivity tool designed to meet the energy analysis needs of Utility DSM departments and of Performance Contractors. In a typical application a building is simulated as-is and compared to one or more energy-saving alternatives. 
MMWIN features Measures to implement and keep track of the results of individual changes to the building operation, equipment, or construction. Measures are grouped into Packages the effect of each of which is fully simulated. An elasticity model is used to apportion overall savings among individual component measures. 
Considerable attention has been given to adapt standard Windows GUI elements to perform operations necessary for building energy analysis. For example, the common edit operation drag-anddrop paste has been adapted to cut and paste building Components from one project file to another. Similarly, the hierarchical structure usually reserved for symbolic file representation and navigation has been adapted to represent the building and its Components. 
Calculations are done on an hourly basis for eight typical days per month. In addition to the usual complement of heating and cooling equipment, water heating, lighting, and equipment, MMWIN can model numerous control strategies, heat recovery strategies, evaporative cooling, industrial processes, and swimming pools.
