Waterworks, Regnemark

The waterworks at Regnemark, together with the waterworks at Islev and Slangerup, were designed based on a design manual that PLH Arkitekter has prepared in collaboration with utility company HOFOR.

The Voluntary Sustainability Class

The future waterworks will be constructed as an oblong building in a beautiful nature area near Køge Creek and will be specially adapted to suit the surroundings. To reduce the visual volume, the building will be divided into smaller units.

The facade that greets guests and employees is made of recycled bricks. This helps to highlight the connection to the existing waterworks and the houses that are already located on the site, while at the same time, giving the building a warm and welcoming look. The other facade surfaces will be made from fiber concrete and thermally modified ash wood, which will be installed vertically to give the longest possible lifespan.

Sustainability is a key focal point for the waterworks at Regnemark. In the design phase, emphasis has been placed on using materials with a long shelf life and low CO2 emissions, just as there is a focus on minimizing energy consumption. The waterworks is the first of its kind to be registered for the Voluntary Sustainability Class, where limits have been set for how much CO2 new buildings may emit, and from which learnings will ultimately contribute to the shaping of future legislation.

Unique waterworks with a common concept

Through thorough analyses of the waterworks' functions combined with aesthetic visions and a focus on sustainability, robustness and longevity, PLH Arkitekter has prepared a comprehensive design manual for the waterworks at Regnemark, Islev and Slangerup. The manual links together function and design, thus forming the basis for all decisions: From the broad lines such as the structure of the works and location of process plants to concrete details such as the choice of facade materials, floors and other elements.

In working with the design manual, the functions of the works have been broken down and divided into three main groups of building blocks, each of which consists of the rooms needed to carry out a function. In this way, the building blocks can be moved around, adjusted in size and adapted to the surroundings depending on the needs of the individual waterworks.

The design manual also ensures that the new waterworks have a consistent appearance and layout – externally as well as internally – so that citizens and visitors can easily identify them as HOFOR's works.

The facades of the three buildings are constructed with a uniform expression in materials such as brick, wooden cladding or fiber concrete, aiming to make the clean, rustic architecture signal efficient, industrial facilities.

The facade materials in the design manual have been selected based on architectural, sustainable criteria, which will ensure high quality and the least possible maintenance in future. The sustainable profile is also seen in the works' energy consumption, which is supplemented, among other things, by solar cells in or around the buildings.
