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 | 230,232 MMBtu | 191,310 MMBtu |
| Electricity from on-site renewables | 15.50 MMBtu | 0 MMBtu |
| District steam/hot water (sourced from offsite) | 0 MMBtu | 0 MMBtu |
| Energy from all other sources (e.g., natural gas, fuel oil, propane/LPG, district chilled water, coal/coke, biomass) | 387,343 MMBtu | 599,974 MMBtu |
| Total | 617,590.50 MMBtu | 791,284 MMBtu |
Start and end dates of the performance year and baseline year (or 3-year periods):

| Performance Year | July 1, 2018 | June 30, 2019 |
| Baseline Year | Jan. 1, 2007 | Dec. 31, 2007 |

Optional Fields
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):
The Residence Hall Council (RHC) Eco-Rep program was established in 2011. Eco-reps are the voice for sustainability within their hall council and educate their peers living in their residential hall to be more aware of their behaviors. They help support campus sustainability efforts by embodying and promoting sustainable living within their residential halls. The RHC Eco-Reps foster sustainable behavior among their peers through fun and educational programs focused on waste and recycling, water and energy conservation, transportation, sustainable food systems, and social equity. They make sure all hall council programs are sustainable and they are the recycling expert in their halls. The RHC Eco-Reps are also the driving force during annual competitions including Energy Conservation Month (fall) and RecycleMania (spring) helping to bring glory (and sometimes prizes) to their hall!
Most of Lehigh's buildings are individually submetered for electric, and these measurements are available to the entire Lehigh community through a dashboard system developed in-house and through Lehigh's partnership with OSISoft and the on-campus deployment of the OSISoft Pi System. At the end of 2017, building automation system data for LEED-gold certified Williams Hall was also added to the OSISoft Pi System for the community to see.
The University has a sustainability leadership team called the Lehigh Sustainability Council (LSC) that meets once a month to review and promote more sustainable behaviors through the faculty and staff departments. The LSC membership was expanded during the past year in part so that it reaches more departments.
A brief description of energy use standards and controls employed by the institution (e.g. building temperature standards, occupancy and vacancy sensors):
The general space temperature settings are 74 for cooling and 68 for heating. Space temperatures in many buildings are monitored and adjusted remotely with the campus-wide building automation system (BAS). In general the BAS does not control lighting but most public areas like classrooms include occupancy, vacancy, or daylight sensors that locally turn off lighting when the spaces are vacant or too bright.
A brief description of Light Emitting Diode (LED) lighting and other energy-efficient lighting strategies employed by the institution:
Building lighting on all three campuses are being changed from a variety of existing lighting types to light-emitting diodes (LEDs). This is also occurring for street lighting throughout the three campuses, both for street lights maintained by the University and those maintained by the local power company. The local power company offers rebate incentive to encourage such projects to be completed, and the University has been taking advantage of the incentives program. Seven buildings and two parking garages have undergoing LED retrofits during the past two years.
A brief description of passive solar heating, geothermal systems, and related strategies employed by the institution:
Lehigh's architecture teams are designing some of these features into new buildings that are being planned for the campus. Construction of several new buildings began in summer 2018. Lehigh is also looking into power purchase agreements to build a large-scale solar photovoltaic system either on or off campus (or both) in the coming years.
A brief description of co-generation employed by the institution, e.g. combined heat and power (CHP):
The University does not use a cogeneration system on site at this time.
A brief description of the institution's initiatives to replace energy-consuming appliances, equipment and systems with high efficiency alternatives (e.g. building re-commissioning or retrofit programs):
All new construction and major renovations are commissioned, and all of these projects aim to be certified to a minimum LEED silver level. For current projects enhanced commissioning and building envelope commissioning are also being performed. Building automation controls in Zoellner Arts Center (ZAC) were upgraded in 2018, and variable speed drives are being added to fan motors at ZAC and in other campus buildings. An HVAC control system upgrade was performed at the STEPS laboratory building and the ATLSS/IMBT Building. The STEPS laboratory building will also received two new exhaust heat recovery systems to replace defunct heat wheels. Future HVAC system upgrade projects are planned for other Mountaintop Campus buildings and the Goodman Campus Stabler Athletic and Convocation Center.
