Proptech start-up hello energy and listed office investor NSI launch strategic partnership to stimulate sustainability and innovation

Start-up hello energy and listed office investor NSI have announced a new strategic partnership. The goal is to provide greater insight into the energy consumption and sustainability policy of NSI, establish benchmarks and communicate the resulting data to stakeholders.

“We are pleased with this new collaboration with hello energy,” says Dennis van der Stoop, Head of Technical Management at NSI. “After increasing the sustainability of our portfolio for years we can now show this to our tenants in detail. We find it important to involve them in our sustainability ambitions and achieve our goals together. In its partnerships with other real estate investors and developers, hello energy has gained a wealth of experience in providing insights to tenants, investors and other stakeholders.”

Sustainability awareness

While the real estate sector is certainly becoming greener, the fact remains that 40% of CO2 emissions are generated in the built environment. This is why NSI aims to develop virtually energy-neutral office concepts, reduce the use of fossil fuels and facilitate circular renovation in the construction chain. This is in line with its sustainability strategy which is focused on Futureproof Investments, Energy & Carbon and Health & Wellbeing.

The sustainable measures now have to become more visible, which will be realised by establishing active communication with all building users via large screens in the entrances and an online dashboard. “We will combine the energy data of NSI with positive sustainability content,” explains Benno Schwarz, founder of hello energy. “This will generate awareness among users and involve them in increasing sustainability.” By giving tenants insight and tips, NSI expects to realise a smaller CO2 footprint over the coming years.


The partnership with hello energy also marks the next step in increasing the sustainability of NSI’s real estate portfolio, which will help improve its GRESB score. This global benchmark prescribes the performance of real estate investors in the field of sustainability. “Partnering with hello energy enables us to add important elements related to stakeholder engagement, tenant engagement and monitoring,” Van der Stoop adds. The energy consumption and waste stream data will also be used to establish a benchmark. This will give NSI insight into the progress made compared to other companies in the sector and share knowledge and experience.
