Like all HAWKES projects, Echo Barn is built upon rigorous low carbon design principles; both in its efficiency in use and in the use of low embodied carbon materials in its construction. In collaboration with a highly experienced timber frame engineer we built a 3d model of the frame which enabled us to optimise its construction efficiency. We could also coordinate the MVHR ductwork into the frame so that the installation would be fully resolved prior to construction on site.

The engineered timber frame enables us to order windows “on plan” with a high degree of accuracy. This enables windows to be delivered to site “just in time” so that they can be fitted as soon as the frame is erected to receive them. This is helpful in that it helps us to seal up the timber frame quickly and free up the interior for fit out trades to progress. By fitting the windows directly from delivery we also avoid double handling and the potential of damage is significantly reduced.
The cavities between the engineered beams within the walls and roof are later packed full with recycled newspaper insulation which is mixed with Boron salt to make it fire retardant and vermin resistant. This highly sustainable form of insulation is an exceptional high performance material with an extremely low embodied energy footprint. The material is also hygroscopic and so can help to regulate and optimise internal Relative Humidity within the building and thus optimise the health of the internal environment passively and not reliant upon active mechanical means.
Our timber frames are also designed to maximise airtightness and in doing so reduce the loss of heat through the thermal envelope. This goes a long way to reducing operational running costs for heating during the winter months.
