2022-04-19 18:46:53 -0500	marked best answer	HAMT: how does it split surfaces into cells? Hello. I am now trying to apply HAMT in my project. In that, there is a thing I cannot understand. When checking Engineering Reference, it says "“Surfaces” are made of a number of layers of potentially any combination of materials. Each surface is split into its constituent materials and is then split up further into cells through its depth." Here, how does the program split a surface into cells? Automatically, or are there any ways to define coordinates of cells by users? In addition, my target has an earth floor. In this case, what kind of the outside boundary of RH is used if I apply HAMT to the floor; always 0 ? (I understand this method is not suitable for vertical water movement underground which is driven by gravity. But I want to know this.) I would appreciate for any kinds of information from you...

2021-01-13 07:44:23 -0500	marked best answer	Surface inside conduction with HAMT I am now trying to apply HAMT in my simulation and want to compare simulated value with the observed value. I have the observation data of surface heat flux of floor. However, I cannot find the output variable of conduction in HAMT output group. I tried using Surface Inside Face Conduction Heat Transfer Rate per Area, but it outputted just 0 for any timesteps. Thus, I think I have to find the output variables about conduction for HAMT algorithm. Is it impossible in the current EP? If you have any tips, I'd like to know. Best regards,

2019-11-15 14:51:37 -0500	marked best answer	Changing Fuel Type in Coil:Heating:Fuel in OS Dear all, now I am trying to modify the fuel type in Coil:Heating:Fuel with OpenStudio. In my understanding, Coil:Heating:Gas was modified to Coil:Heating:Fuel in the current version of EP and OS have not prepare the input for fuel type. So, I would like to modify the fuel type with OpenStudio measure (is this OK?). Though I wrote the measure as below, it didn't work. I think I don't understand so many things. So, any tips from you will be helpful. # see the URL below for information on how to write OpenStudio measures # http://nrel.github.io/OpenStudio-user-documentation/reference/measure_writing_guide/ # start the measure class ChangeFuelTypeInCoilHeatingFuel < OpenStudio::Measure::ModelMeasure # human readable name def name return "Change Fuel Type in Coil:Heating:Fuel" end # human readable description def description return "This measure is used to change the type of fuel in Coil:Heating:Fuel of HVAC.

2019-04-18 05:46:27 -0500	marked best answer	How can I check ground heat flux? Dear everyone on Unmet Hours, I am now working to apply EP to agricultural production in greenhouses. I have observed data of temperature, humidity and ground heat transfer. Because, usually, ground in greenhouses is exposed, the condition of floor is so different from the other types of building. So, I want to check how ground heat flux is estimated in EP. But rdd file doesn't include any output variables related to ground heat flux. In this case, is there any way to check ground heat flux? I need any kind of tips from you. Thanks.

2018-09-21 08:34:34 -0500	marked best answer	Calibrating the model with PAT in hourly time step Hello. I am now considering how to calibrate the model using PAT cloud computing with EC2. I understood that PAT can do the multiple simulation and calibrate the model by energy consumption. But in my case I'd like to calibrate the model using observed room temperature (or/and humidity). My idea is like; Here, I don't know how to get the CSV file of the best simulation's result generated by the measure "Export Variable To CSV". I'd like to know any kinds of tips to do this kind of experiment. Thank you.
