Re: [EnergyPlus_Support] OPEN STUDIO - few questions about material,

["Julien Marrec julien.marrec@xxxxxxxxx [EnergyPlus_Support]" <EnergyPlus_Support@xxxxxxxxxxxxxxx>]

Hi,

I would suggest you follow through the Introductory tutorial here: http://nrel.github.io/OpenStudio-user-documentation/

Defining materials and construction is covered here: http://nrel.github.io/OpenStudio-user-documentation/getting_started/getting_started/#constructions-materials-and-the-building-component-library-bcl and the following video is about HVAC. While the interface (and capabilities) of OpenStudio have changed slightly since some of these videos were done, the general idea is still the same.

You can specify a cooling and a heating thermostat on the ThermalZone tab, as well as assign Zonal systems there. There is one specific system that is call "Ideal Air loads" which is useful for heating/cooling loads calculation if you don't have a specific HVAC system in mind yet, and can be enabled by simply ticking the box "Ideal Air loads" next to the zone name (and making sure you input a heating and a cooling thermostat for each zone you want conditionned).

Please also note that official support for OpenStudio happens on www.unmethours.com and not on this mailing list.

Best,

Julien

Dear Support team,

we are totatlly new here, with EnergyPlus and OpenStudio, so therefore, we have some questions.

In attachment is my simple model (1 story building with 2 windows on the south side).

My questions are:

1. How can I make my Construction, Exterior Wall (inside do outside) with this specs of material:

 - Internal Surface Coefficient (U=8.290 W/m2*K and Resistance =0.121 m2*K/W) 

 - Plasterboard (k=0.160 W/m*K, Thickness = 0.012, U=13.333 W/m2*K and Resistance=0.075 m2*K/W, Density = 950 kg/m3 and Cp = 840 J/kg*K)

 - Fiberglass quilt (k=0.040 W/m*K, Thickness = 0.066, U=0.606 W/m2*K and R=1.650 m2*K/W, Density = 12 kg/m3 and Cp = 840 J/kg*K)

 - Wood Siding (k=0.140 W/m*K, Thickness = 0.009, U=15.556 W/m2*K and R=0.064 m2*K/W, Density = 530 kg/m3 and Cp = 900 J/kg*K)

- External Surface Coefficient (U=29.300 W/m2*K and Resistance = 0.034 m2*K/W) 

 TOTAL air - air  (U=0.514 W/m2*K and Resistance =1.944 m2*K/W) 

 TOTAL surface - surface (U=0.559W/m2*K and Resistance =1.789 m2*K/W) 

2. I would like to have the whole space (at my model) with constant temperature of 20°C or constant temp of 26°C. How and where in Open Studio do I put/drag heater or cooler to my model and where exactly do I change presets (temperatures etc.)?

3. Does OpenStudio have presets for my model, how does OS know that 24°C is the temperature where it needs to start cooling. How can I change to 27°C?

4. When I push RUN button, system shows some results, but only put Weather Data to it. How and where can I see other results?

Best regards,

Andrej
