A new energy-efficient house that is capable of providing energy to the grid is being constructed outside of Malmo, Sweden. The house amalgamating energy preservation, energy revitalization and energy generation is a result of joint efforts by Karin Adalberth, a doctor of building physics and E. ON, a local green utility company. Dubbed as “Villa Akarp”, the positive net energy dwelling will invest into buying energy from the utility during winters and will sell electricity to the grid during summers.


An estimated 4,000 kilowatt-hours of electricity will be sold by the house annually, while as far as the purchasing goes only 2,600 kilowatt-hours will be bought. Villa Akarp will include a number of energy efficient technologies like wool fiber insulation that will line the home’s walls, foam insulation lining the foundation of the structure and triple-glazed windows will be incorporated to prevent air from escaping while also letting in lots of natural light. Nearly 32 square meters of solar panels will be installed to generate power during sunny summers. As far as the heating and hot water goes, a Passiv Haus heating concept will be blended with a solar thermal system and traditional radiators. Incorporating green design principals, Villa Akarp will cost a whopping $100,000.
