Energy supply

• Creating a climate balance sheet for a building is helpful for the development of measures through which venues can reduce their CO₂ emissions and energy consumption.

• Energy consumption can be checked and recorded on a regular basis. This enables sustainability officers to recognise inefficient patterns and implement improvement measures. Electricity meters in different building units can be used to identify areas of activity.

• Photovoltaic systems, geothermal energy or heat pumps are sources of green or renewable energy. Their use reduces CO₂ emissions in a sustainable manner. This makes energy provision more environmentally friendly.

• By means of self-generated solar power, venues have the opportunity to a) become less dependent on fossil fuels, b) contribute to the decentralisation of the power grid and c) improve their own energy balance sheet.

• Those who check whether the public power grid can provide renewable energy on a temporary basis will find it easier to source sustainable electricity and switch to renewable energy.

• Rainwater and grey water may be collected and used for toilets and irrigation. This conserves valuable water resources.

• Discussions with landlords on the use of green electricity can be an important step towards a more sustainable energy supply.

• Certified green electricity provides a reliable and environmentally friendly power supply. It can be identified, for example, by labels such as “ok-power” or other green energy certifications.
