The ultra-modern 29-storey tower in the centre of Bangkok was designed to accommodate different types of offices in an architecture inspired by sustainability and health. The building harvests rainwater, which is reused to cool the rooms. Each floor is 3 metres high and fully glazed, with a 15 cm raised floor that houses the systems letting each workstation control its own lighting and air conditioning. The offices are reached through a lobby overlooking the ground-floor gardens of more than 1,000 square metres.

Valsir radiant systems with Mixal multilayer pipes were chosen for the underfloor cooling.

What it shows for a Finnish project

In an office building the pipework for underfloor cooling is chosen by thermal expansion and hygiene. MIXAL is Valsir's composite pipe system for potable water and heating distribution: multilayer PE-Xb/Al/HDPE structure, drinking-water-approved PE-Xb inner layer and thermal expansion about 8 times lower than plastic pipes.
