Natural water from a well / aquafer under the hotel provides 100% free cooling for all the air conditioning without the use of heat-pumps or chillers.
The air conditioning system is extremely efficient and costs almost zero to run. 1kW of electricity is used to produce 10kW of cooling.
The air conditioning system does not use refrigerants, just water. It is becoming more widely known that the manufacture and disposal of refrigerants is harmful to the environment. In the Iveagh Garden Hotel, there are no refrigerants flowing throughout the building, just water
The very small amount of electricity that is required for this comparatively environmentally friendly air conditioning system is generated on site.
Free heat, a by-product of on-site electricity generation is used to heat water for the hotel.
The kitchen canopy ventilation system recovers waste heat and reduces fire risk by preventing grease building up in the ductwork.
Electricity is generated on site and all the waste heat is used by the hotel. Even though natural gas is a fossil fuel and it is used to generate the electricity for the hotel, all the heat, which is a by-product of power generation, is used by the hotel. Generally, in power stations, most of this heat is wasted.
Very efficient motors are used for all fans and thermal wheel heat recovery ventilation is used whenever possible.
The kitchen canopy ventilation system was designed to reduce the risk of fire in the ductwork and at the same time recover waste heat which is used to heat the building when required. It is possible to also use this waste heat to partially heat the water used by the hotel. By reducing odours and eliminating grease from the kitchen canopy exhaust, it has been possible to exhaust at low level from the building.
