Hello all,
I am currently using Openstudio 1.14 on my windows 10 computer, and I have a question about the 'enable demand control ventilation' BCL measure. I understand how demand control ventilation (DCV) is supposed to work in a real building, but I'm not sure about how it's implemented in Openstudio. I'd like to know, since in the model it seems to have a big impact: my 'baseline' building (2-storey multi-use university building, heat from gas boilers distributed by VAV system) has an EUI of 56kbtu/ft2. When I apply the 'enable economizer control' measure (fixedenthalpy option) that doesn't change EUI at all, but when I apply DCV it goes all they way down to 39kbtu/ft2. The thing is, other than selecting the VAV air loop that serves the entire building, I didn't do anything specific to implement the measure- there wasn't any "click her to apply the CO2 sensor to this space" option or anything like that...so how exactly does DCV get implemented by the measure? What is it assuming about locating C02 sensors and calculating the CO2 level (presumably from occupancy & activity space type schedules)?
