Figures needed to determine total building energy consumption:
Performance Year Baseline Year
Grid-purchased electricity 496,772 MMBtu 397,858 MMBtu
Electricity from on-site renewables 0 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) 463,388 MMBtu 647,380 MMBtu
Total 960,160 MMBtu 1,045,238 MMBtu

Start and end dates of the performance year and baseline year (or 3-year periods):
Start Date End Date
Performance Year May 1, 2017 April 30, 2018
Baseline Year May 1, 2004 April 30, 2005

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):
---

Gross floor area of building space:
Performance Year Baseline Year
Gross floor area of building space 7,737,597 Gross square feet 6,498,958 Gross square feet

Source-site ratio for grid-purchased electricity:
2.05

Total building energy consumption per unit of floor area:
Performance Year Baseline Year
Site energy 0.12 MMBtu per square foot 0.16 MMBtu per square foot
Source energy 0.19 MMBtu per square foot 0.23 MMBtu per square foot

Percentage reduction in total building energy consumption (source energy) per unit of floor area from baseline:
14.93

Degree days, performance year (base 65 °F / 18 °C):
Degree days (see help icon above)
Heating degree days 9,015 Degree-Days (°F)
Cooling degree days 157 Degree-Days (°F)

Floor area of energy intensive space, performance year:
Floor Area
Laboratory space 2,654,176 Square feet
Healthcare space 0 Square feet
Other energy intensive space

EUI-adjusted floor area, performance year:
13,367,433.90 Gross square feet

Building energy consumption (site energy) per unit of EUI-adjusted floor area per degree day, performance year:
7.83 Btu / GSF / Degree-Day (°F)

Documentation (e.g. spreadsheet or utility records) to support the performance year energy consumption figures reported above:
---

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):
---

A brief description of energy use standards and controls employed by the institution (e.g. building temperature standards, occupancy and vacancy sensors):

Centralization using Delta controls allows for schedules (start-stop) of all HVAC systems. Office and classrooms with digital thermastats are connect to this system. In addition, many systems, the make-up of fresh air is adjusted according to the level of occupancy and several VFDs were installed on air conditioning systems and pumps.


A brief description of Light Emitting Diode (LED) lighting and other energy-efficient lighting strategies employed by the institution:

The LED is a standard in all new project.


A brief description of passive solar heating, geothermal systems, and related strategies employed by the institution:

We convert district cooling system in hydrothermic system. We installed 24 heat pumps that uses the return of the cold water to heat buildings (the water is at 55F). The total capacity oh the 24 heat pumps is 1700 tons or 20 400 MBTU. For the district energy system, this technique is more optimal and similar to the geothermal energy. An exothermic building allows to heat another with this system.


A brief description of co-generation employed by the institution, e.g. combined heat and power (CHP):

The description above can be used.


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):

Since september 2018, the institution uses renewable natural gaz to replace 8% of the total natural gas from fossil issue.
