Hello. I am modelling a residential project. Trace700 has already 90.1 plants library. However if you calculate PTAC efficiency manually you have to use table 6.8.1D. Using that table EER depends of thePTAC capacity (7000 Btu/h and 15000 Btu/h). Where as in Trace the equipment called "90.1-04 Min PTAC New Cons All Cap" has 0.804415 kW/ton for all capacities. Does anyone have used Trace700 library equipment for 90.1 compliance? -- MSc Oscar Buchely Ingeniero de Proyectos Soluciones Energ?ticas Sostenibles www.ses-ingenieria.com Bogota - Colombia Tel +57 1 6192633
