Active Thermal Mass Solutions
High powered heating & cooling
The use of both air and water within the mass offers design engineers and consultants powerful options in providing low energy comfort. Actimass has pioneered the development of these techniques and have patent protection for this technology worldwide. The Actimass air and water system offers the most powerful thermal mass cooling potential available with at least 90W/m2 achievable.
The mass can be used in the same way as an air based system during occupied periods of the building and the incoming ventilation air is tempered as it travels through the mass of the concrete.
If additional or rapid heating or cooling is requires the water based circuit can be activated. The pipe sits between the air path and the room ceiling soffit and so when activated it quickly changes the convective temperature of incoming ventilation air and then the radiative effect of the ceiling.
Air based night cooling techniques can still be used to cool the building mass when conditions are
Air & Water Systems

Benefits of the air & water based system
High power cooling and heating potential
Fast action response
Controllable temperature band thermal mass conditioning
Low energy and low carbon emissions
favorable. However, if there are periods where the diurnal night temperatures do not drop sufficiently to give efficient cooling the water pipe can be used to ensure the mass is cooled. The system offers all the benefits of passive, air and water systems but also some of the benefits listed above.
Systems can be designed so that only the appropriate passive, air, water or Actimass air and water system is used in the appropriate area of the building. Actimass engineers with discuss each area and recommend the appropriate solution to meet current and future needs.
