[Equest-users] Help - eQuest - Controlling Space Heating Fuel Oil Consumption

[Sami, Vikram]

I would start with the weather file. Check and make sure that December is indeed similar to January. In most places January is actually significantly colder than December.

I would then check the schedules. Do you have more holidays & weekends in December for the schedule assigned? (For example some years you will have 10 weekend days in December and 8 in January).

Good Morning Everyone,

We are working on an energy audit for the Tarrytown Municipal Housing Authority just north of NYC. We have developed a model going through the wizard and moving on to the detailed mode to enter more specific data concerning space heating and DHW systems. We feel that our numbers are accurate however when we simulate the building performance, the graph indicates the highest space heating fuel consumption in January which dips down into a "valley" where in in July through October, no space heating is indicated. In november, it begins to creep back up however, the graph indicates that in the month of December,  less than 1/4 of the fuel needed to heat the facility in January was used, which is plain and simply not the case. December and January should indicate similar fuel consumption for space heating. Does anyone know how to tweak the model so that the graph will dip down into a "valley" indicating no fuel consumption for space heating only in the summer months (June, July, August) while maintaining the same annual total fuel consumption currently modelled? We are using New York, NY ("newyony") weather data from the DOE2 website. Any suggestions would be helpful. Thanks.
