Energy and buildings
As part of the Long Term Agreement (MJA-3), the Erasmus University has an Energy Management System (EMS). It stipulates how the target of an annual energy efficiency improvement of 2% in the period 2005-2020 is being pursued. The ambitions stem from the MJA-3 agreements between the EUR, other Dutch universities and the national government. The EMS describes the roles and responsibilities of those involved in the EUR within the framework of energy management.
On 11 December 2013 the Energy Policy Statement was signed by the Chairman of the Executive Board. This statement is part of the energy management system (EMS). Another part of the EMS is the energy-audit, which is performed yearly. During this audit it is examined whether all the arrangements are clear and that the documentation is in order. The audit in 2017 was completed successfully.
Energy Efficiency Plan 2017-2020
The Energy Efficiency Plan (EEP) describes the activities that are undertaken to reduce the energy consumption. Continuously, for a period of 4 years, the EEP is prepared to achieve the 2% energy efficiency improvement per year. In 2016 the EEP 2017-2020 (Dutch only) was drafted. This will be the last in the present MJA3 period. The plan provides for a 10% improvement in energy efficiency within this period and contains measures on how to save energy. A major contribution to the energy efficiency improvements for the coming years are due to the new energy efficient buildings which are to be build and systems for thermal storage (ATES systems). Through such installations the buildings will be cooled down much more efficiently.
In 2017 the EUR consumed 42,001 GJ of heat from the district heating system, 16,207 MWh of electricity and 89,200 m3 of water. The electricity has slightly increased in 2017 compared to 2016; this is due to the increase in functional surface area. The consumption of water also increased because the number of students increased. In contrast to electricity and water, less heat was consumed in 2017 compared to 2016. This is because 2017 was slightly warmer than 2016, so less heat was needed.
The EUR’s energy annual report provides more detailed information on energy consumption. You can find some figures about consumption between 2006 and 2017 in the graphs below.
Energy saving measures
The ambition of the EUR is to improve the energy efficiency by 2% annually from 2005 onwards. This improved energy efficiency will be achieved through the implementation of energy saving measures. The different measures taken in the past years are included and described in the Technical Manual. These measures are implemented in case of renovation and in case of a new building being constructed. The EUR expects the Technical Manual to easier facilitate the implementation of different measures. Examples of these energy savings measures are replacing the window glass by insulating, sunlight reflective HR++ glass, the installation of an active warming/cooling ceiling to be prepared for the connection to a heat /cold storage system and the installation of energy saving lighting controlled by daylight and movement. Also the insulation of the roof is a measure that can be taken when renovating a building. A large number of energy saving measures has been carried out in the sustainable renovation – which started in 2015 – of two buildings: The Sanders Building and the University Library. They are reopened in 2017.
When implementing measures in buildings the university always weighs the relative interests of the three Ps: people, planet and profit. It is sometimes necessary to opt for less energy-efficient solutions in the interests of creating a good working environment or for commercial reasons or because the opening hours of buildings are being extended. Consequently buildings might be using more energy.
