Thermo-Active Building Components
Thermo-active building components (TABS) actively integrate the solid structure of the building in the temperature management system.
The best solution is to insert pipe lattices into the ceilings and / or walls of each storey, which can be charged and / or discharged by circulating a warmer or cooler fluid through the pipes. Only a small temperature difference relative to room temperature is needed. For cooling the TABS extract heat from the room, while for heating they emit heat to the room.
It is therefore possible to use renewable or environmentally friendly energy to offset that supply/demand imbalance by, for example, using cool ground water or the cooler temperatures in the ground under and around the building to supply cold water (16-19 °C) which is fed into the pipe lattice in the ceiling to cool it. During the day, heat is absorbed from the room via the ceiling, air-conditioning the space.

The day/night temperature variations are used in the way that the delay in the storage process balances the time differences that exists between supply and demand.
The specific cooling capacities are up to about 42 W/m2 in case of a bare ceiling, or up to about 35 W/m2 in case of a ceiling with suitable thermal acoustic panels.
Comfortable Room Climate
Heat (cold) is transferred by radiation. For the user this is the most pleasant method of conveying heat / cold. People in the room are not affected at all by the air that is being warmed / cooled by radiation, since the surrounding surfaces are cooler than body temperature.
Because large surfaces are available for heat exchange in hydronic radiant cooling systems (usually almost the whole ceiling or walls), the coolant temperature is only slightly lower than the room temperature.
Thermo-active building components are very efficient in combination with a geothermal cooling system!

More benefits:
- Increase in the energy efficiency of buildings.
- Straightforward use of renewable energy sources
- Reduction in the energy requirement
- Minimisation of CO2-emissions
- Cost reduction through the use of natural resources
- Due to the high heat capacity and density of water, thermal energy can be transported in water in pipes with little pump power.
- Radiant cooling is a draft free system
- Cooling is more evenly distributed,
- Once room surfaces reach a desired temperature they tend to maintain that temperature with relatively little extra energy.
- Unencumbered interior design
Since radiant cooling systems are constructed of components from the radiant heating and air conditioning industries, components are widely available. There are however relatively few engineers experienced in residential radiant cooling design. GPI engineers have many years of experience in installing these systems.
Investing in solar power and renewable energy now builds energy independence and moves us towards a healthier future.
