High energy demand – high materiality
It is no surprise that EVVA has achieved high relevance and impact values in the materiality analysis with regard to "energy". As an industrial company that supplies countless high-quality access systems all over the world, EVVA has a corresponding energy requirement. We need most electricity for our manufacturing processes, e.g. for machines/manufacturing 50%, compressed air/compressors 22%, cooling 8% and workplaces/PCs 7%. Gas is required for heating. 55% of our purchased electricity comes from renewable sources. Saving energy and extracting it from renewable sources has therefore been identified as a key sustainability topic in stakeholder dialogue.
The specified measurement data is published in EVVA environmental reports and in the energy audit. These are externally audited and confirmed by authorities (e.g. environmental agency, waste management agency, trade authority, representatives of the Chamber of Labour and the Chamber of Commerce) and by sustainability consultants.
Energy requirement (electricity/gas)
Total energy requirements (electricity, gas) of the EVVA headquarters incl. main production facility, from 2015 to 2019
Energy intensity per kg of product or per m²
Energy intensity for electricity and gas from 2015 to 2019, related to consumption within headquarters with main production site. Another key figure: In 2015, the total energy consumption (electricity, gas) per employee was 12,838 kWh, in 2019 13.220 kWh. According to the external energy audit, this puts EVVA in the midfield compared to other metalworking companies.
The energy requirements of the EVVA headquarters converted into CO² tonnes in 2019. Source for calculations: external audit 2019 (denkstatt enertec) with estimation based on current experience as well as the CO² emission factors from the Austrian Federal Environment Agency (for electricity: 0.248 kg CO² equivalent per kWh; for natural gas: 0.271 kg; for petrol: 0.327 kg)
More efficient production despite increasing production figures
- According to our Environmental Report 2020 and Energy Audit 2019 (external auditors: denkstatt enertec), electricity consumption at EVVA headquarters with our main production facility in Vienna increased during the reporting period (from 4.3 gigawatt hours GWh in 2015 to 5 GWh in 2019), but less than the increase in EVVA production of 4 to 5% annually. Reason for higher power requirement: More electronic and also more complex mechanical access systems are in demand, which offer greater security, but include a wider part diversity. The more complex production processes and machines require more energy, but also replace numerous older production facilities. A new digital machine can replace up to five conventional machines
- Heating gas consumption could be reduced from 1.6 GWh in 2015 to 1.4 GWh in 2019, partly due to greater recovery of waste heat in production.
Production has therefore become more efficient overall: EVVA produces more, but requires far less electricity and gas to do so. The numerous energy-saving measures listed below have had a very positive effect in the company. And we will continue our activities. This is because the demand for energy is growing due to ongoing digitalisation and new Clean Production machines, which require far fewer resources such as oil and water, but which require more electricity. Progress in energy efficiency is therefore necessary to ensure that the positive effects are long-term.
For all these reasons, the topic of "energy" was classified as essential by the stakeholders. It is linked to emission reduction, which is addressed in each of the following measures. EVVA sets ambitious targets to compensate for additional requirements, increase energy efficiency and reduce emissions.
Significant energy-saving measures –
positive effects since 2015 and targets for 2024:
With the following measures in particular, EVVA is able to counteract its increased energy demand. The kilowatt hours saved in this way currently account for about 8% of the annual electricity demand.
- More video conferences, digital meetings and teleworking
EVVA had already put more emphasis on digital communication and training before the Covid-19 crisis in order to reduce travel expenses. During the pandemic from the beginning of 2020, usage increased particularly and business trips declined accordingly. As EVVA would like to resume its export activities in the event of a normalisation of the health situation, business trips – especially to new markets – will continue to be necessary and important. However, we expect that especially shorter journeys and business trips will increasingly be replaced by video conferences.
- Company vehicles with electric drive
The energy consumption of the EVVA fleet at the headquarters has been reduced by approx. 300 MWh (300,000 kWh) in the last four years, which is roughly the energy consumed by 15 private households per year. This reduction is attributable, among other factors, to the merging of journeys as well as the optimisation of routes, e.g. of field staff. In 2018, two electric vehicles were purchased at EVVA Vienna to gain experience with electrically driven vehicles. After the test phase, the purchase of several e-company cars will be evaluated.
EVVA Netherlands is the Group's pioneer in e-fleet vehicles. 4 electric cars have been in use for years and employees are very satisfied with them. New acquisitions are currently not planned, as longer-term leasing contracts are still in place for the other vehicles with conventional fuels
- Travel allowances from EVVA for employees commuting from other federal states to the headquarters. They amount to 7,800 euros per month for 90 employees. These subsidies only apply to public transport, not to cars. This means they have a steering influence and reduce the environmental impact of individual transport.
- Clean Production. EVVA’s much lower oil requirement also means fewer oil transports from refineries to EVVA – and the oil does not have to be disposed of in a time-consuming manner. More information under Clean Production
- Focus on regional suppliers. The closer the sources are, the shorter the transport routes. More details under Proportion of regional suppliers
- The server rooms at the headquarters have been cooled for many years using natural cooling. This means that when the outside temperature is approx. 10 degrees below the desired inside temperature, cooling is no longer carried out via compressors, but via the outside air
- Virtual servers. EVVA already uses virtual servers for many hardware systems, resulting in lower energy consumption. Around 300 virtual servers are currently in use at the headquarters, which are operated by 6 physical servers. As a result, each EVVA service can be handled via its own server, which greatly reduces dependencies (e.g. during reboots). Saving energy by: EVVA only needs around 50,000 kWh per year for the 6 servers – unlike the many dozens of servers from earlier with a total of around 330,000 kWh per year
- e-screwdriver. In 2019, EVVA replaced 24 pneumatically driven installation screwdrivers with 24 electrically driven ones. This not only reduced noise emissions, i.e. the noise level experienced by fitters, but also cut energy consumption by 3,000 kWh per year.
