Eco Friendly Hotels
The main consumers for energy in Ayii Anaryiri Health Spa-Hotel are the usual suspects. Heating and cooling of the facility is the main consumer and in due to the hot and dry weather in Cyprus cooling during the extensive summer month is the main problem.
The second consumer was found to be the light of the facility which due to the fact that in the hotel lighting is needed nearly all day round. This problem was firstly approached with a more natural way. Daylight as mentioned above (architectural), is provided throughout the building with large windows and glass façade. Great importance was given to the efficiency of the lighting of the building, by using Led’s instead of incandescent bulbs which consume a lot of energy. Also all the rooms have sound and motion sensors, so that when the room is not in use, electricity is not consumed.
A complete B.M.S (Building Management System) is installed from where the maximum demand can be controlled, all the external lighting as well as common lighting can be time controlled and the operation of all mechanical systems can be controlled, therefore all the systems run at the most economical way.
Another significant consumer is the electricity for the function (filtration) of the swimming pools. By installing solar pumps combined with photovoltaic panels, we have managed to have almost zero consumption of electricity for the function of the swimming pools.
Save Energy Technologies
From the beginning, the importance of designing a building as ‘green’ as possible, with low energy consumption, was one of our great expectations! Especially regarding the mechanical systems, this is the most important part, electricity wise. The only resort in the island implementing all sources of renewable energies.
Save Energy Mechanical Systems of Hotel – Spa
The Hotel – Spa uses mechanical systems which are specially designed to save energy. The mechanical systems work with Geothermal for the heating and cooling of the building and hot domestic hot water (normal and sulphur) as well as heating of the spa indoor pools. Solar Energy is used for hot domestic water (normal and sulphur) as well as heating of the spa heating of the indoor pools. Also, Solar Energy (Photovoltaic Panels) is used for the function of the pools. Below each system is explained separately.
- Geothermal energy has been used for centuries for bathing and heating water. It is extracted from the earth’s natural heat in dry, steam or liquid form and can be used for electricity and heating. In Europe, the ‘heat pump’ is the most promising way of using geothermal energy. This consists of extracting heat from hot, shallow geothermal fluid and transferring it to water or air which is used to supply heat for space heating. Even at shallow depths of 50-100m, the earth harbors heat that can be extracted by heat pumps – often located in the gardens of suburban houses – and used directly in domestic heating. Heat can also be returned to the earth for storage as a way of ‘air conditioning’ homes and buildings.
- The Geothermal system consists of 19 heat pumps and 140 vertical geothermal heat exchanges of 100m depth each
- 5 are high-temperature brine-to-water heat pumps. They are used for the heating of the domestic water (normal and sulphur) they are also used for the heating of the indoor pools of the spa.
- 14 of them are VRV III Water Cooled Inverter Heat Pumps. They are used for the heating and cooling of the building.
Solar Thermal: Solar thermal (ST) is one of the most cost-effective renewable energy systems. Solar thermal water heating systems collect the sun's energy in the form of thermal or heat energy. The system can save a major portion of your utility bill.
Solar thermal is used for heating the domestic water (normal and sulphur) of the hotel and the spa, as well as heating of the indoor pools of the spa.
Solar thermal is also used for heating the area of the spa (under-floor heating). 90 Solar Panels are used for the Hotel- Spa for hot domestic water and heating.
- Photovoltaic System: Photovoltaic energy is the most promising and popular form of solar energy. With Photovoltaic panels, sunlight is actually converted into electricity. This is very different from a conventional understanding of solar power as only a way of heating water.
Using all the above renewable energy systems and energy saving systems the resort can achieve 40-45% savings in electrical and energy consumption.
