Carbon Footprint

The university prepares an annual report on carbon impacts based on the GHG protocol. The emissions rate in 2021 is 18,985 tons of carbon dioxide distributed as follows. The University emitted an estimated 6,206 MT CO2e through the consumption of electricity produced at the central utility plant. and 6,668 MT CO2e through the consumption of HVAC produced.

1. Electricity 2482 MT CO2e
2. AC units 3723 MT CO2e
3. Chiller 701 MT CO2e
4. Transportation 8 MT CO2e
5. Housing 4415 MT CO2e
6. trash-hazard materials 4 MT CO2e
7. trash-non-hazard materials 9 MT CO2e

The following chart represents the distribution of the emission.

EJUST reduces carbon dioxide emissions through the following.

• Campus landscaping

Greening the university layout can help in mitigating the heat stress, thus it can help reduce the cooling loads of building, as well as sequester carbon from the atmosphere and store it in the soil. EJUST gives priority for greening a wide area of its site. In the first phase of EJUST main campus (Fig 1,2), the total buildings area is 66975m2, whereas the total green area is 70867m2, which represents about 1:1 floor area to green area. In the future, in the next construction stages (Fig. 3), the building area will not exceed 18% of the total site area, however the green area will be tripled.

In this report, the first phase of EJUST main campus (opened in Feb. 2019) a total of 1152 kg CO2e has been subtracted due to the greening areas and the planted trees area and type of the campus landscaping.

The outdoor air in Alexandria is generally mild during mid-seasons and winter. This presents a good potential for cooling buildings by natural means.

In current design, the building heights are generally low. This guarantees that buildings in a downwind direction could receive adequate natural ventilation. In order to further enhance overall ventilation performance, a wind path could be created within E-JUST.

Strategies:

Recommendations regarding facilitating natural ventilation include:

1. Allow sufficient proximities between buildings or other structures (approximately 0.7 to 1 time of adjacent building height, as illustrated in Figure 7) to allow wind penetration.
2. Create wind paths within E-JUST. One possible way would be to align primary roads („neurons‟) in parallel with annual prevailing wind direction.

Natural Ventilation

Over the main campus buildings, there are large-scale solar chimneys used for building ventilation.

• Renewable energy generation

EJUST provide the campus by Solar Energy is located on the secondary campus of the Egyptian Japanese University and has a total capacity of 560 kilowatts. The solar cells are distributed in three places: Plaza, Atrium, and Parking. The station has a control room and an inverter room. The total power generation of the station is divided as follows:

• The Plaza unit consists of 620 cells with a capacity of 325 watts per cell. The total power generation from the Plaza unit is 200 kilowatts.
• The Atrium unit consists of 720 cells with a capacity of 85 watts per cell. The total power generation from the Atrium unit is 60 kilowatts.
• The Parking unit consists of 920 cells with a capacity of 325 watts per cell. The total power generation from the Parking unit is 300 kilowatts.

The output power of the PV station was connected to the loads in the south and north buildings and the administration building as well as the light loads of the parking, atrium, and plaza. The PV station statistics from January 1, 2022, to December 31, 2022, are as follows:

The total energy generated from the photovoltaic system during 2022 reached 136 MWh. It saves 110,000 EGP (as the KWh price is 0.80 LE) and reduces emissions by 96 metric tons of carbon dioxide.

Clean transportation

In the main campus, electric cars are used in the interior transportation

• Clean transportation

In 2010 the transport sector was responsible for 22% of global CO2 emissions worldwide. 1 Global transport related CO2 emission are expected to increase by 57% in the 2005 – 2030 timeframe, representing the fastest growing source of greenhouse gas emissions worldwide (IEA “CO₂ Emissions from Fuel Combustion - 2012 Edition” (2012) Paris: International Energy Agency). A reduction in driving could have a measurable impact on slowing the process of climate change by reducing harmful tailpipe emissions.

EJUST has supported the campus with four electric golf cars and one bus to facilitate transportation within the university without generating any emissions. Also, EJUST launched a policy in cooperation with New Borg Elarab authority to upgrade the city streets based on the complete street policies by adding a dedicated bike lane between E-JUST main campus and HQ campus (about 3 Km) and facilitating 100 bicycles for moving between both campuses. It is expected to reduce the daily trips between both campuses using cars by about 300 Km.

• Renewable energy generation
• Generating Electricity and water heating from Solar Energy
E-JUST uses solar energy as a clean source for electricity generation. With the collaboration of Japanese partners, a 0.56 MW PV system has been installed in the secondary campus. Also, EJUST uses in students housing building, solar collectors for water heating instead of electrical heaters.
