The technical heart of Nathan Zevenaar:
from the bridge over the railway you can't miss Nathan's new building. A sleek, modern building, designed based on the very latest in technical climate solutions. It represents the beating heart of Nathan, as a new office for employees, but above all as a knowledge and expertise centre for sustainable climate technology. The entire ground floor is reserved for the 500 m2 showroom and the education and training centre for the Nathan Academy.
Unique construction with a unique result
The new building, like the old office in Duiven, is heated and cooled by means of an open-loop aquifer thermal energy storage (ATES) system. To this end, two source holes were bored by Nathan Projects in July 2017. The source filters are installed in the second aquifer at a depth of between 60 and 90 metres. The sources are connected to two alpha innotec SWP heat pumps, each of 45 kW.
In Nathan's new building, concrete was very deliberately chosen. Concrete possesses the necessary mass for concrete core activation. It therefore forms the core of the new air-conditioning system and supplies approximately 85% of the building's heating and cooling needs. It ensures a stable indoor temperature in both winter and summer. The precast concrete slabs are prefitted with Uponor PE-Xa pipes for ceiling heating and cooling, cast-in sprinkler connections, electricity and ventilation ducts in the airdeck factory.
This results in a unique construction with a unique outcome. The concrete floors of the first and second floors and the loft therefore have all their technical installations precast in the concrete. The floors are also fitted with underfloor heating and cooling. An Uponor tackerboard system using a 16x2 mm PE-Xa pipe is used for underfloor heating and cooling throughout the building, including the warehouse area.
Varicool heating and cooling panels were installed to the meeting room's ceiling. The new hydronic system replaced the old fan coil unit system. Varicool system is a radiant heating and cooling system. The panels do not heat or cool the indoor air directly but the surfaces what radiant covers.
La dalle active Uponor est intégrée depuis 2017 dans l’immeuble Delta Green, bâtiment tertiaire de 4600m2 comprenant 4 niveaux. Celui-ci est le premier bâtiment de la région tout à fait autonome en énergie.
Le bâtiment d’enseignement supérieur et de recherche pour l’Institut Mines-Télécom intègre un système de dalle active sur une surface de 40 000 m2. Le bâtiment économe en énergie accueillera une gamme variée d’activités propres à l’Institut Mines - Télécom : formations, recherches, transfert et innovation.
Thermal concrete core activation with Uponor Contec provides economical, energy-efficient and sustainable building temperature control in the new landmark Adlershof Science and Technology Centre.
A hygienically optimal drinking water installation was integrated into the new office complex – thanks to Uni Pipe PLUS within a very short time.

Uponor were nominated as the sole supplier for radiant heating systems for the Sunesis Schools schemes, with Main Contractor Willmott Dixon. Sunesis is a Joint Venture between Scape and Willmott Dixon, built on the combined experience of public sector know-how and private expertise. They are the market leader in delivering pre-designed buildings across a range of market sectors. Every design has a defined layout, specification, fixed cost and timescale to construct. The full benefits of a full BIM model are also utilised.
