Structure Cooling

A new way of cooling our buildings efficiently

May 2019

Structure Cooling prevents heat from entering living spaces through a system of pipes that absorb heat from the building structure.

Oorja's Structure Cooling system is based on the simple fact that heat load due to the Sun is actually borne by the building structure and gets embedded as heat in the thermal mass of the building. If the heat from the structure can be flushed out before it enters the living spaces, this would lead to significant reduction in usage of air conditioning and can eliminate it in most cases. Structure Cooling uses the evaporation of treated waste water to supply water at 20-27°C to the piping network embedded in the building slabs to evacuate the heat embedded in it. The solution completely eliminates the need for compressor based cooling and fan motors to transport cooled air leading to savings of over 90%. Structure Cooling also prevents the build up of heat in the building thermal mass during harsh summers in tropical climates as the heat radiating from the structural masses like walls and ceilings is the main cause of discomfort for building occupants.
