|In the house “Villa Ro” the light is allowed to play in many ways throughout the year by exciting window placements and configurations. The indoor has a close contact with the patio, greenhouse, the enclosed garden allows the owner who lives in the house drink the coffee out almost all year round, listening to the spirit of rustle in the leaves. The house is built as a passive house and keeps a comfortable temperature indoors all year round by recovering system of the ventilation and a stove as a central heart of the house. Central in the house there is a Jötul stove (for wood fire) with two meters of uninsulated chimney which allows the heat to spread quickly in the house. Total energy consumption 6000 kWh/year, 85 kWh/m2. Take a look inside! >>|

New build single family house in the central parts of Borgholm. The construction follows the criteria for passive house standard, but also to become beautiful. The aim was to use natural material and to make it as maintain free and with a high energy performance. It is a one family house with a tower room with balcony. The house has no windows on the north facade. The windows are facing south where they provide maximum interaction between outside and inside. External cladding is pinewood from the northern parts of Sweden treated with natural wood treatment or lime wash. Indoors, all the walls lined with white waxed pine paneling. The roof is coated with sedum and ceiling with panels of cement bonded wood wool. The housing is ventilated and has heat exchange, with a heat recovery of about 85%. Wood burning stove with convection outflows provides warmth and nice atmosphere. District heating provides hot water and any additional heat in the coils in the floors. The estimated energy consumption is estimated 45.04 kWh / m2 year.

|New built library in Mönsterås. The PV on the roof produces the same energy amount that the building requires on a yearly basis. The outdoor lighting is LED. The heating is supplied by district heating, produced by waste heat from the nearby pulp industry, (biomass). The energy usage and energy production is monitored in the entrance hall. The roof is partly sedum. The sedum roof insulates and minimizes the load on the water system since the rain water is drained to the groundwater. The thick walls, the airtight construction and well insulated walls guaranties a very low level of heat losses. Heating and ventilation is split up in sections to reduce the energy consumption and give the highest air quality possible. The library has 70% less energy demand than a traditional building.|

House N in Växjö. New build premises to the university of Växjö with low energy standard. The construction is wood and it was completed in 2011. The demand was 30% energy consumption below the Swedish requirement (77 kWh/m2 and year). After running the house in two years the measured consumption is as low as 59 kWh/m2 year. House N was the first in Växjö to achieve the “Green building” certificate.

Single family house with for passive standard in Östra Göinge. The estimated power consumption is 11W per square meter. The owner was one of seven finalists in E.ON 's energy contest E-prize. The house has solar thermal panels and PV panels for production of electricity and heat. The house has a unique system for preheating air by s system of tubes (containing 33% ethanol) in the lawn, especially developed for this house. The system works well and at a cold winter day with -23 degrees outdoors the inflow of the air was -3 degrees. Summer time the inflow- air is cooled by 10 degrees, and the lawn is recharged with heat.
