electricity consumption of a building

[farah89]

I am working in my intership on building energy. I want to determine the consumption of a building daily. I have the daily consumption of the whole university campus and not of each building separetly. Is there a way to estimate the daily consumption of one building of this campus ?

 

[IRstuff]

one could presumably scale the building consumption to match the campus consumption on the assumption that each square foot of occupancy has roughly the same power needs.

Otherwise, you should contact your facilities department.

I contacted them but there can not help me, they did not have the information.
I think i can not use this assumption you mentioned because the use of buildings is different ( administration, research labs, classrooms ). So, is there another assumption which matches this case?

You could try searching for estimating tables, which surely exist.

Or you could roam the campus with an Amprobe, sampling the current consumption of everything in a given room at a given time, and integrate over time for each type of room, etc.

Yes, walk around and write down how many people you find in each building, and what electrical devices are in use. Then ask the people how long each device is used each day.

The buildings with the EE labs use a bit more.

If the building occupancies are all the same, you can simply apportion by square footage. This is highly unlikely, though.

For typical building energy use by building occupancy, look at energystar.gov or doe.gov, there are tables that list the total annual energy use per square foot average for classroom, office, health care, etc...

You could then estimate a weighting factor for each of your buildings.

In my business, we have to document things like that -- so step one would be to install temporary (or sometimes permanent) meters on the individual buildings for a period of time.

Good on ya,

You can just come up with an average if you don't need to find a unique footprint of each building.

Most substations will have some sort of metering available. In this day and age, I would be surprised if the institution did not have some form of sub metering available, for basic accounting purposes.

I spent about 9 months working at a large university in Chicago years ago. Many questions I had for facilities management went unanswered. Working with the electrical staff directly was useful in resolving these issues.
