Best method to define individual space properties

I am setting up an OpenStudio model for an architectural project and there are quite a lot of spaces where I have to define unique properties for occupancy and ventilation. More specifically they are labs with fume hoods.

I've defined high level information as space types and placed local properties onto the spaces in the "Spaces" tab. However, the space type definitions remain part of the calculations.

Space Load Properties

Zone Name        |  Floor Area {m2} | # Occupants | Area per Occ {m2/person}| Occ per Area {person/m2}  
THERMAL ZONE: 514 ADV CHEM TL    167.93    25.0           6.70                    0.15

Is there a way to override the space type properties when a local load has been defined in the "Spaces" tab?

What are the best methods and practices when it comes to defining properties for individual spaces in OpenStudio?

I found this old question here but it seems to no longer be relevant with new versions of OpenStudio.

I don't think there's a way to tell OS to not use the SpaceType's load when you add your own load of the same type.

Instead you'll have to define a space type "Lab" with all common loads such as equipment etc, but no People. And each of the spaces of type lab should have their own specific People object added.

It'd be quite easy to setup a simple script that would load a mapping of Space Name => People into a ruby structure (a hash for eg), then you loop on the "Lab" space type's spaces, and if you find the space name in the hash's keys, you assign its value, otherwise you assign a default value.

Thank you for your answer. I should really learn Ruby and the OpenStudio SDK. It seems like I could automate a lot of my tasks.
