NIRAVANA
The Bahamas private house on the beach was a competition project. The site for a villa was located on the stunning place just near the seaside. A detailed project of accomplishment and gardening with the natural environment and landscape is secured. Our concept was to create a house as an arranged landscape with terraces cascade that falls to the sea. The maximum use of the space and benefits of the exceptional location.
The main vision of the house - open house integrated in landscape: lack of borders between the indoor and outdoor space, the natural landscape visually supposed to be part of the house, the walls "cut" and freely cross the volume of the house, the main entrance located in the middle of the land site, the house has two levels. The first level of the house includes garage, technical and subsidiary rooms. The second level - living area.
Arrange several visual sights from windows – trees, bushes, decorative elements etc. Isolation from East and a West side from the neighbors. The height of the main living room 4.5 m and other rooms 2.8 m as minimum. In summertime – maximum openness to the environment. During the winter – maximum closeness from the seaside with the blinds protection from wind and rain.
The building was designed from concrete bearing construction; some walls can be lined with natural dolomite. Terraces located around the house - from wood and stone. Platforms – from concrete, stone and sand. The colour scale of the interior is supposed to be light, neutral and natural. The colour of the furniture and design elements will be chosen by matching to materials of walls, ceiling and floors.

Systems for cooling of the building.
According to the local climate, natural ventilation can be possible only for a short period of time during the year. All the rest of the time during the season the rooms have to have air conditioning.
Preconditioned outside air supply for each room - 1-3 air changes per hour will be arranged, that will keep comfortable indoor stay. Air filtration in the air handling unit – filtering, dehumidifying and cooling.
Dehumidification will be controlled by dew point temperature, to prevent the condensation in the building envelope.
To lower room temperature, concrete slab will be cooled till 20C by built in chilled water pipes. That will give good thermal stability and lover peak cooling loads.
Water-cooled chiller with heat rejection via heat exchangers to the swimming pool, hot water preheating and outside air. For noise reduction to the surroundings, a chiller is placed in the technical room.
The employee and guest spaces will be air-conditioned by multi split units and mechanical air handling units for basic air exchange.

Aspects of energy saving.
Heat rejection from chiller to the swimming pool and hot water preheating. High COP for chiller plants is reached with high chilled water temperature. Then low temperatures will be produced with separate split units. Supply air is zoned with variable air boxes or smaller air handling units, to minimize the energy consumption for air treatment.
Load bearing walls are disconnected from the rooms, therefore many walls can be made from glass. Load bearing walls also give a possibility to break strong winds and separate sand, water mist.
Main vapour barrier is glass and hydro-concrete.
