A novel application of sustainable material sourcing and building performance monitoring: case study based approach.

In this research, a novel use of building materials and their impact on the building performance and its climatic adaptability is explored, based on a complex real word case study of a unique low energy sustainable building project. In particular, an innovative use of sycamore and its suitability as a structural and constructional timber has been investigated and reported, considering that is deemed not appropriate for structural applications by current standards. A research method of in-situ longitudinal study has been adopted, concentrating on the performance monitoring and assessment of its structural performance and conditions in which it might deteriorate. On the system level, the climatic adaptability of the building as a whole has been analysed via dynamic performance simulation and compared to the in-situ measurements. This was important in order to develop a holistic building performance monitoring strategy, but in particular, to understand the impact of building microclimate on the sycamore frame and hempcrete components of the external load-bearing wall. So far research has concluded that sycamore can be used as structural and constructional material in building design, but due attention has to be paid to construction detailing and provision of a breathable, low humidity environment with an effective resistance to decay and insect attack. This includes measures that ensure a low equilibrium moisture content conditions, effective ventilation provision and appropriate service class uses.
