Eco Factor: Energy positive house incorporates energy saving and generating technologies.
Villa Akarp seems like any other ordinary home design with an exception that its roof is laden with 32 square meters of photovoltaic panels. However, deep in its bones will be the systems that will not only make it a low carbon dwelling, but also ensure that its inhabitants earn money by selling excess energy to the grid.
Designed by Karin Adalberth and local utility company E.ON, the Villa Akarp is being built outside the Swedish city of Malmo. The team worked out that the residence would purchase energy from the grid during the long winter months and sell electricity back during the sunny summer months.
With several energy saving systems put in place that includes 5.5 decimeter thick wall line, foam insulation and triple-glazed windows, the house is expected to sell back about 4000KWh of electricity annually, while purchasing just 2600KWh, creating a positive net energy ratio. The designers estimate that the house will cost about $100,000 more than conventional homes, but the residents can surely recoup some of that in terms of energy savings.
