Uponor Involvement

250 sqm
Uponor Teporis ceiling cooling, Uponor PEX-a pipe underfloor heating and invisible supply air duct are installed in the whole villa, except kitchen and bathroom area. DOAS (dedicated outdoor air system) in parallel with radiant cooling system entirely designed by Uponor Asia Engineering & Design, has been applied in the project. 100% of the internal latent load (3.2kW) and 30% of the internal sensible load (3.75kW) are covered by the DOAS. The remaining sensible load (8.75kW) is covered by the Uponor radiant cooling & heating system and controlled by Uponor Smatrix Wave Plus individual room temperature controller. Uponor Smatrix Wave Plus provides individual thermal comfort in each room and at the same time highest energy savings.

Uponor Teporis system is ideal for residential villa. Panels are possible to integrate lighting, ventilation and electrical plug, which give high level of freedom for interior design and furnishing. The absence of radiators, fan coils and other cumbersome devices also help owners to utilize all spaces in the villa. With Uponor Teporis gypsum panel high cooling capacity, energy is exchanging between surfaces and the surrounding areas by radiation with no air movement involved. The temperature of the water in the radiant panels is between 15°C and 18°C in cooling mode and between 35°C and 40°C in heating mode to achieve high level of thermal comfort.
