The district heating net is a pipe network that supplies heating and hot water for connected consumers from a central power plant. It is a more efficient way to provide heat and power compared to localized boilers. District cooling is the cooling equivalent of district heating. Working in accordance to similar principles, district cooling delivers chilled water to buildings like offices and factories. Trigeneration is when electricity, heating and cooling are combined in the same plant.

Responds to the following needs

A reliable and clean water supply is an essential need but a large number of people currently lack this basic provision. Solar water pumps is a socially and environmentally attractive technology to supply water. Especially if the need for water is in remote locations which are beyond the reach of power lines, solar power is often the economically preferred technology.

Cooling is becoming a rapidly emerging demand in developing countries, which signifies that the building design and shell measures need to reduce cooling loads, and the efficiency of air-conditioning will need to be improved. Air conditioning systems are implemented in numerous sectors, namely buildings, industry and transport. They are distinguished in two main categories, room air conditioners and central air conditioners.
