Introduction

  • This presentation shows Energy Use Intensity (EUI) for various building types in the City of Minneapolis
  • The energy is presented separately for public and private buildings
  • The data is available for the years 2014-2017
  • Here we just show the data for 2014-16

Overall Public Buildings EUI

wnsiteEUI is weather normalized EUI which nullifies the effect of weather on EUI

EUI for Public Buildings (>10 instances)

Inferences on Public Buildings (>10 instances)

  • Parking EUI is almost constant
  • Office EUI has a decreasing trend for EUI with building area
  • Entertainment/ Public Assembly EUI has no meaningful data (constant at zero area!)
  • School data also generally appears to have a decreasing trend with building area

Overall Private Buildings EUI

EUI for Pvt. Buildings (>25 instances)

Inferences on Pvt. Buildings (>25 instances)

  • Hotel EUI has a decreasing trend for EUI with building area when area <500,000 ft^2
  • Mixed Use Property EUI does not show a clear trend but can be better analyzed if outliers are removed
  • Offices, just like public office buildings, show a decreasing trend for EUI with area
  • Private Parking EUI is also constant just like in the case of public parking buildings

Refrences & Footnotes

  • The data to build this presentation was downloaded from: http://www.minneapolismn.gov/environment/energy/benchmarking

  • Note that although we are able to catch a trend for wnsiteEUI vs area in some instances, there might be other variables that influence EUI to a greater extent

  • These variables might include - building materials, HVAC Systems, building designed to exceed energy model codes
