Contributing to a site waste management plan at the
design stage results in quantified reductions in waste arising. This is achieved
by evaluating recycled content and specifying building materials containing
higher recycled content as well as reused materials.
MACH sees waste as
careless, unsustainable and economically costly. If we did not have
ears, partition thickness, slab depth, glass thickness, doors, etc. could be
made considerably lighter, meaning that less material would be required to build
a building. As such, within building design there is a balance between
the materials needed for a high acoustic performance, and the reduced mass for
a low energy, cost effective design. It is therefore critical to ensure that
the correct performance standards and design strategies are used to make sure
that the right acoustic performance standard is achieved without over
specifying in order to minimise waste and embodied energy.
Often, acoustic treatment forms an integral part of the
important architectural appearance of a building. It is often the case that
over design occurs. However, MACH always looks to minimize waste by
investigating a wide range of products and materials and carrying early
reverberation time testing which allows us provide very accurate area of
treatment and eliminate over specification.
The roof to Eden’s Educational Building is formed from a
timber structure. Thermal insulation made from recycled newspaper was used to
provide the thermal insulation. To achieve the acoustic requirements of the
exhibition space the plywood sheet used for lateral bracing was perforated to
20% open area. This principle has been used across a range of schools, higher
education buildings and other MACH projects.
