Key Environmental Performance Indicators
With reference to the main environmental aspects, some of the key performance indicators recorded for 2024 are presented below, with 2023 figures for comparison.
Energy
ENERGY CONSUMPTION PER SQUARE METER
Total energy consumption (electricity, gas, district heating, diesel, gasoline) per total square meters of built space
| Year | Var 1: Energy Consumption (GJ) | Var 2: Surface Area (m2) | KPI Value (GJ/m2) |
|---|---|---|---|
| 2024 | 94.119 | 331.673 | 0,28 |
| 2023 | 96.292 | 331.673 | 0,29 |
TOTAL GAS CONSUMPTION
Total cubic meters of gas consumption
| Year | KPI Value (Sm3) |
|---|---|
| 2024 | 352.180 |
| 2023 | 442.690 |
Note: Decrease in gas consumption recorded in 2024 is mainly due to the still-undergoing replacement of gas boilers by heat pump systems for the heating and cooling of buildings.
INCIDENCE OF ENERGY SELF-GENERATION FROM RENEWABLES
Percentage of self-generated energy (GJ) in total energy consumption (electricity, gas, district heating, diesel, gasoline)
| Year | Var 1: Self produced energy (GJ) | Var 2: Total energy consumption (GJ) | KPI value (%) |
|---|---|---|---|
| 2024 | 4.259 | 94.119 | 4,5% |
| 2023 | 4.911 | 96.292 | 5,1% |
Note: The small decrease in self-generation from photovoltaic panels is essentially due to the less favorable weather conditions in 2024 compared to 2023 (fewer hours of solar irradiation).
Air, Water and Soil
WATER CONSUMPTION PER CAPITA
Total cubic meters of water consumed and total number of users (faculty, staff, students)
| Year | Var 1: Water (m3) | Var 2: Users (no.) | KPI Value (m3/no.) |
|---|---|---|---|
| 2024 | 205.877 | 18.006 | 11,4 |
| 2023 | 199.043 | 17.309 | 11,5 |
WATER DISPENSERS’ PER CAPITA CONSUMPTION
Liters of drinking water dispensed by water dispensers (excluding those in residences) per total number of users (faculty, staff, students)
| Year | Var 1: Water (l) | Var 2: Users (no.) | KPI Value (l/no.) |
|---|---|---|---|
| 2024 | 601.775 | 18.006 | 33,4 |
| 2023 | 667.590 | 17.309 | 38,6 |
Waste
MUNICIPAL WASTE PER CAPITA
Kilograms of municipal waste produced by total number of users (faculty, staff, students)
| Year | Var 1: Municipal waste (kg)* | Var 2: Users (no.) | KPI value (kg/no.) |
|---|---|---|---|
| 2024 | 219.967 | 18.006 | 12,2 |
| 2023 | 207.596 | 17.309 | 12,0 |
*Average weight of garbage bag for each waste fraction multiplied by the total number of bags produced
INCIDENCE OF RECYCLING
Percentage of sorted waste out of total waste produced
| Year | Var 1: Sorted waste (kg) | Var 2: Total waste (kg) | KPI value (%) |
|---|---|---|---|
| 2024 | 89.137 | 219.817 | 40,6% |
| 2023 | 63.916 | 207.596 | 30,8% |
QUALITY OF WASTE COLLECTION
Percentage of compliant material present in the unsorted waste fraction*
| Year | Valore KPI (%) |
|---|---|
| 2024 | 38,1% |
| 2023 | 14,7% |
*Valori ricavati dalle analisi merceologiche condotte periodicamente a cura di AMSA (dati riferiti al mese di dicembre di ogni anno).
SPECIAL WASTE PER CAPITA
Quantity of special waste sent for disposal by total number of users (faculty, staff, students).
| Year | Var 1: Special waste (kg) | Var 2: Users (no.) | KPI value (kg/no.) |
|---|---|---|---|
| 2024 | 14.338 | 18.006 | 0,79 |
| 2023 | 9.912 | 17.309 | 0,57 |
Note: The increase in special waste production is due to the 2024 acceleration in the decommissioning of non-hazardous electronic equipment (e.g. monitors and PCs) following the modernization of computer rooms and other spaces used for teaching activities, and the replacement of lighting fixtures (e.g. fluorescent lamps) with more energy-efficient LED devices.
Mobility
BICYCLE RACKS PER THOUSAND USERS
Number of bike racks on University property per 1,000 users (students, staff, faculty)
| Year | Var 1: Racks (no.) | Var 2: Users (no.) | KPI Value (no.) |
|---|---|---|---|
| 2024 | 598 | 18.006 | 33 |
| 2023 | 487 | 17.309 | 28 |
BUSINESS TRIPS MADE WITH SUSTAINABLE MODE OF TRANSPORTATION
Number of business trips made using trains booked through travel agencies out of total number of trips made within an 800-kilometer radius.
| Year | Var 1: Trips using sustainable transport (no.) | Var 2: Total trips (no.) | Var 2: Total trips (no.) |
|---|---|---|---|
| 2024 | 7.247 | 8.322 | 87,1% |
