Project description:
‘Duinenwater’ is a charming new residential area in Knokke on the edge of a 12-hectare lake. The bright newly built apartments are surrounded by green but within walking distance of the beach, the golf, the shopping streets and the railway station.
The interiors of the apartments are voluminous and equipped with all modern amenities. In the design of the technical installations, the focus is mainly on determining the desired level of comfort for the residents (sufficient heating, cooling, enough sockets, warm ambient light, sanitary hot water supply, etc.) while keeping energy costs to a minimum. We focus on using sustainable techniques such as optimal use of daylight without additional cooling requirements. Thanks to the southwest orientation and large sliding windows and spacious living terraces, you can enjoy the last rays of the sun in summer and winter, indoors and outdoors.
Based on this, several sustainable techniques were applied, including a mechanical ventilation system D in phase 1. In the case of balanced ventilation, both the supply and the exhaust take place mechanically via a network of ventilation ducts and fans. The exhaust air heats up the supplied (cold) air thanks to a heat exchanger.
A healthy and comfortable living environment has a major influence on the resident/user. For example, the occupied rooms must be sufficiently heated or cooled without creating a draught. Because the supplied air is heated, it enters the rooms at a pleasant temperature and creates a comfortable interior comfort. Moreover, by recovering the heat, the energy consumption decreases, resulting in a lower energy bill and E-level. Finally, since the supply air is also filtered, dust, pollution or pollen remain outside.
In phase 2, a switch was made to a C+ ventilation system, extraction in all rooms, demand-driven. This means that the ventilation flow rate is increased when the air quality is reduced.
Energetically, this means that when the occupants are absent, the ventilation unit switches to a lower operating mode.
