We create design strategies that make your building sustainable.
Non-conventional, low energy & accessible to everyone.


We design the best natural comfort strategies for your home, office or building. These strategies are not only sustainable and cheaper, but also reduce energy consumption and improve comfort.

These specialized strategies can have significant impact on the energy usage and comfort of buildings, but often fall outside the scope and/or expertise of design team members. We can assist in any or all of the project stages. By providing design input and support, sustainable strategies are included in your building design.

Our team.


Dolf finished his Master's Degree in Physics of the Built Environment at Eindhoven University of Technology in 2012. He started working for Imtech Building Services, a mechanical contracting company, where he specialized in the performance of complex dynamic systems. In 2015, Dolf moved to South Africa to work for PJCarew Consulting. As a Green Building Consultant, Dolf ran his own Passive and Low Energy design team which implemented sustainable and efficient systems in various projects both in South Africa and the Netherlands. 


Late 2018, Dolf left PJC to start Climetric BV. After 1.5 years, Dolf moved back to the Netherlands in the beginning of 2020. While working on local projects, he supports the South African projects remotely.


Etienne completed his Industrial Engineering degree at the University of Stellenbosch, South Africa, in 2005. He started working at PJCarew Consulting, a Cape Town based consulting firm focussing on passive and low-energy design. Etienne developed analysis tools and calculators to aid the decision making for water, climatic, energy and daylight strategies. He also worked on and managed several Green Star Certifications and energy modelling submissions.

In 2015, Etienne started Susti, a company specialising in South African SANS XA Rational Design modelling. Susti merged with Climetric in 2018. Etienne is based in Cape Town, South Africa. From this location, he works on local projects while providing support for European projects.
