How a biobased living concept saves you money on your energy bill

The Dutch company Strotec has developed a living concept with environmentally friendly materials like straw. Houses can be delivered fast and inexpensive by prefabricating the parts. Strotec uses the so-called Ecococon-concept of the eponymous company from Lithuania. This concept has been further developed and applied to the Columbus Residence Strotec, where a combination of straw and clay are incorporated in the prefabricated walls. Residents can benefit from a healthy indoor climate, because these vapor-open facades create an optimum moisture and CO2 regulation.

The Columbus House has a higher isolation than a traditional house, according to the construction company. Therefore the biobased house has a lower energy requirement. The house can be delivered energy-neutral by providing the Columbus House with solar panels, a heat pump and a heater that is heated with wooden pallets. Besides this there is no need for a gas connection and generates as much electricity as is used during the year.

Building with straw
A remaining question is will the construction sector pick up this sustainable living concept. "There is a lot of demand, but nothing really happened yet," says Jan Walrecht, partner at Strotec, to Cobouw. "The building industry is traditional in this regard. Unknown makes unloved. However, it is a matter of time, with more stringent CO2 regulations, the market will come by itself, and building with straw will be a necessity ". The prefabricated straw panels of Ecococon are certified in Lithuania according to the standards of the Passive House.
