This is how you save energy

Ekwadraat helped us make the tomato farm more sustainable. At a time of great uncertainty, Ekwadraat assisted us with innovative and reliable solutions. Advice, calculations, permits and subsidy applications, they took care of it all for me. Ekwadraat is a very competent energy consultancy.

The New Afsluitdijk will be completely energy neutral. The aim is to achieve this as much as possible with Dutch innovative sustainable concepts. This will also give a boost to the sustainable energy sector. Ekwadraat advises and guides us in the development process of these initiatives. Thanks in part to their energy advice, we expect to be able to realize the first projects soon.

Ekwadraat helped us to realize solar panels on our roof. There was a difference of 30,000 euros between the various suppliers' offers. With Ekwadraat's independent guidance we were able to make the right choice for a supplier that suited our needs. This saved us a lot of money on the cost of the installation.

We want to be a favorable development region in the North of the Netherlands and Leeuwarden for companies, knowledge institutions and residents to make the transition to the circular economy. This means that we as a municipality make every effort to facilitate circular initiatives. That is why we are actively deploying a Circular Economy Booster from Ekwadraat within the municipality.
