Rental homes with conservatory
Banne-Oost Amsterdam
The brief includes 35 dwellings. Following from the urban development context, part of these dwellings have to form a wall. The opening-up for cars is situated along this wall. The dwellings square to this wall can only be reached by means of a gate and a footpath. In this lay-out we opted for a comb-shaped allotment. On the north-side, the dwellings can be reached directly from the footpath.
The private gardens are located on the south side. The hedges that will be placed and maintained by the city district will serve as boundaries between the gardens and the footpath.
Water is an important issue in the houses. Rainwater from
the gutter is collected in a rainwater storage tank. The rainwater is
used for the toilet flush.
Water-saving showers and taps are also used.
The average consumption of drinking-water is reduced by approximately 40%.
A thermal solar collector on the roof produces domestic hot water. The hot water is stored in a 120 liters storage tank. A high efficiantie stove is used for additional heating of the water.
A mixing manifold mixes hot and cold water to the right temperature for the laundry. This appendage increases the solar collector system efficiency and decreases the use of electricity.
According to the EPN (the Dutch standard for energy performance), the annual consumption of natural gas in the dwellings will be approximately be 450 m3. This means 50-60% less energy consumption compared to todays standards for new estates in Amsterdam. This reduction is realised by means of an increased insulation standard (Rc= 3.5), high efficiency glass (U=1.4), conservatories, enclosed porches and solar boilers for hot tap water.
