For this 120 ping (395m2) luxury residence we design and implement a package of energy saving measures, that provides a very comfortable living atmosphere, as well improves the durability of the building. Beginning with the structure; several techniques are applied to save energy, such as thermal insulation, good water proofing, air tightness, and double pane glazing. The climate installation is centralized and provides fresh filtered air through the house via an anti- bacterial piping system. Cooling, dehumidifying and heating are integrated. Domestic hot water is supplied by an all-in-one machine: insulated water tank, heated by an air-to-water heat pump, with an additional solar thermal panel on the roof. The PV solar installation is designed to cover the total electricity consumption of the house. Apart from energy saving lighting, smart solutions for entering of daylight in the darker parts of the house are applied, too.
