BaleHaus: A low carbon solution for buildings using prefabricated panels made from renewable materials

Roberts, Haf; Beadle, K; Mander, T; Parnaby, Richard; Walker, P; White, C

Abstract

The construction of a low-carbon building using renewable materials is described and air tightness and breathability details explained. The BaleHaus at Bath is the first prefabricated straw bale house to use ModCell (Modular Cellulose) panels. It is an innovative, offsite manufacturing system that can produce buildings with thermal performance over one and a half times greater than current Building Regulations. Straw is considered a natural, low carbon and renewable material providing high levels of thermal insulation. Straw bale construction has historically been used to varying extents, but the modern development of a wholly prefabricated load-bearing panelised housing system is a new concept. Panel design, fixings between panels and adjoining features and performance testing is described. The panels must be robust to meet modern construction demands, such as load-bearing capacity, fire resistance, thermal transmittance and acoustic performance. The BaleHaus, built on the University of Bath campus, has been designed to explore the possibility of meeting the PassivHaus standard of less than 15 Kwh/m2/yr, meaning a low or no heating requirement. Air tightness tests carried out show that the BaleHaus has potential to deliver to PassivHaus standards.
