How do you prove Thermal Comfort compliance via Energy Modeling? I use DesignBuilder and I am tasked with proving LEED T

So how did you go about it? Or maybe figured out a solution since?

Hi, everyone! English is a second language for me so distinctions between those terms are a bit confusing to me.

Here are my assumptions for heating period so far:

Heating load - is the amount of energy a space with occupancy and plug loads needs to receive in winter to maintain its temperature within set points (no air changes or re-circulation or anything else; mostly energy transfer except for infiltration).

Heating demand - is the amount of energy an HVAC system will provide to condition that space and to condition outdoor air before supplying it to the space.

Heating consumption - is the amount of energy that will be consumed by that HVAC system to satisfy the heating demand. [If the system uses only electric heaters then demand = consumption; if the system uses heat pumps then demand > consumption).

Are my assumptions reasonable? Please, correct me where I am wrong.

My follow up question would be: where can I see each of these values in the DesignBuilder simulation report? Or EnergyPlus report?

Thanks!

I am beginning to create a proposed model of a medical ward for the purpose of LEED certification. The building has over 150 AHUs of the similar type (CAV and 100% OA). Do I have to create each AHU in the proposed model or can I somehow approximate them into few? I can't seem to find what Appenndix G says about that. I am using DesignBuilder.

Hi! I am creating a geometry of building in DesignBuilder and there is a significant amount of concrete columns in a parking garage area and in some occupied spaces. I assume that thermal masses of those columns shall not be excluded for the purpose of accurate modelling. Which methodologies (specific to DesignBuilder or not) do people use to acount for effects (on energy consumption) of such constructions in a modeled building ?

P.S. The model is for LEED.
