Mainstreaming

Building types by construction system

Each project from this practice evolves unique to its site, clients and development priorities.

Even so, as the numbers of completed projects grows, both the environmental systems integrated and the construction approaches utilised find repeated applications.
Thereby mainstreaming of environmental approaches toward conventional industry processes occurs.
The environmental systems are described separately.

Construction systems

Here, the emphasis is on the construction approaches which fulfill environmental goals.

Broadly these are:-

  1. insulated light weight framed structures e.g. Portals
  2. as above, but using pre-fabrication
  3. mixed framed and masonry structures
  4. Hebel insulating masonry
  5. masonry structures using a variety of materials

Discussion

In the hot arid lands of this practice's service area, well insulated lightweight framed structures perform well with the climate responsive comfort systems used by this practice.

In timber framed structures, the opportunity arises to use recycled or plantation grown timbers. Occassionally on-site timber sources are part of the resource stock.

However, on many sites there is no suitable building material to hand, disturbance of the site would lead to long term environmental damage locally, and the transport cost of most materials choices is uniform.
Here pre-fabrication off site and hand tool installation of lightweight steel structures on-site is attractive for its benefits of site protection during construction and resistance to pests.

Hebel is autoclave aerated concrete (AAC) which constructs as masonry block but with air inclusions forming insulation integral to the block. This contributes to comfort in buildings.

Some sites are suited to masonry structures, where the thermal mass assists the building to maintain comfort.
Few of the projects of this practice use conventional brick or brick veneer construction; those few noted here were developed with the clients understanding of the sub-optimum performance of that material mix. The choice was driven by preferences for conventional appearance rather than environmental performance.

However, some projects use environmental masonry solutions including site collected surface stone, rammed earth and mud brick.

There is also a stream of projects which mix these construction approaches. Notably, pre-fabricated insulated building envelopes introducing thermal mass masonry elements.

There is no single general solution for everyone, not even when measured against environmental criteria alone, let alone when measured against a mix of requirements including client preference and societal expectations (as imposed by town planners in their ignorance).

The projects listed below simply show the mainstreaming of environmental solutions from this practice by the repeated application of these distinct construction approaches.
Many of these projects are individually described on separate files.
