Eco's ECO2H2OUSE claims speedier construction and ability to meet Passivhaus low-carbon housing standards

At this year's Ecobuild event a new building system to meet Passivhaus construction standards for low-energy homes will be launched.

Developed by UK-based company Eco, the ECO2H2OUSE uses a modular laminated veneered lumber to create a robust frame, which the company claims is faster to construct than both conventional brick-built and traditional timber-framed houses.

To overcome the issue of overheating in lightweight structures, the system uses water to provide thermal mass. The water, which is stored in tanks strategically located throughout the house, captures excess heat during hot periods to prevent the building from overheating and helps ensure a more even internal temperature throughout the year. It can also be used to maximise passive solar gain in winter, thereby reducing the heating requirement.

Eco says the modular make-up of the system provides architects with the freedom to create individual designs, using the frame as a base, for a wide variety of building types. Different insulation products and renewable energy features can be supplied, depending on the building's location and requirements.

A cut-away of the building will be on display at Ecobuild, offering the opportunity to see under the skin of the system.
