Total 537,555.97 MMBtu 537,555.97 MMBtu

Start and end dates of the performance year and baseline year (or 3-year periods):
Start Date End Date
Performance Year Jan. 1, 2018 Dec. 31, 2018
Baseline Year Jan. 1, 2018 Dec. 31, 2018

A brief description of when and why the building energy consumption baseline was adopted (e.g. in sustainability plans and policies or in the context of other reporting obligations):

Our baseline year was adopted in 2018 due to the lack of accurate data collection previously.


Gross floor area of building space:
