Part 1
This credit is based on energy inputs from offsite sources and electricity produced by onsite renewables. When the institution purchases one fuel and uses it to produce heat and/or power, you should enter only what is purchased. For example, if the institution purchases natural gas to fuel a CHP system and produce steam and electricity, only the purchased natural gas should be reported.
| Performance Year | Baseline Year | |
| Grid-purchased electricity | 275,860 MMBtu | 285,056 MMBtu |
| Electricity from on-site renewables | 563 MMBtu | 0 MMBtu |
| District steam/hot water (sourced from offsite) | 36,313 MMBtu | 6,080.80 MMBtu |
| Energy from all other sources (e.g., natural gas, fuel oil, propane/LPG, district chilled water, coal/coke, biomass) | 530,989 MMBtu | 639,488 MMBtu |
| Total | 843,725 MMBtu | 930,624.80 MMBtu |
Start and end dates of the performance year and baseline year (or 3-year periods):
| Start Date | End Date | |
| Performance Year | July 1, 2017 | June 30, 2018 |
| Baseline Year | July 1, 2007 | June 30, 2008 |
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):
The building energy consumption baseline was set at FY2008 because it is the year in which UWM made an official, concerted effort to plan to reduce energy use on campus. This has been the campus baseline since 2010.
Gross floor area of building space:
| Performance Year | Baseline Year | |
| Gross floor area of building space | 7,895,881 Gross square feet | 6,159,081 Gross square feet |
Source-site ratio for grid-purchased electricity:
3.14
Total building energy consumption per unit of floor area:
| Performance Year | Baseline Year | |
| Site energy | 0.11 MMBtu per square foot | 0.15 MMBtu per square foot |
| Source energy | 0.18 MMBtu per square foot | 0.25 MMBtu per square foot |
Percentage reduction in total building energy consumption (source energy) per unit of floor area from baseline:
27.08

A brief description of the institution's initiatives to shift individual attitudes and practices in regard to energy efficiency (e.g. outreach and education efforts):
In coordination with campus-wide Performance Contracting between 2009 and 2014, UWM ran an extensive outreach program across campus and with particular focus on buildings undergoing performance contracting. In subsequent years, UWM has continued outreach through the Green Office program to target individual and department-wide practices that can aid in energy efficiency.
A brief description of energy use standards and controls employed by the institution (e.g. building temperature standards, occupancy and vacancy sensors):
Variable air volume boxes and controls have been implemented in numerous buildings. Temperature set points and setbacks are regulated by the JCI extended architecture Metasys system.
A brief description of Light Emitting Diode (LED) lighting and other energy-efficient lighting strategies employed by the institution:
LED Lighting has been utilized in the outdoor space surrounding Sandburg Hall. The canopy is lit with e-conolight Series E-CC 38W LED lights. In addition, cast aluminum exit signs feature LED lights, though do not count toward this credit. Interior renovations and retrofits across campus are increasingly using LED replacements.
A brief description of passive solar heating, geothermal systems, and related strategies employed by the institution:
Passive Solar Heating is incorporated into several of the more recently constructed buildings on campus such as the School of Architecture and Urban Planning building, constructed in 1992. Use of Lake Michigan water as a heat sink in the central plant cooling process is an incredibly efficient process which negates the need for extensive building electric chilling units.
A brief description of co-generation employed by the institution, e.g. combined heat and power (CHP):
