Sam from Creative Earth Landscaping and Phil Withers (Phillip Withers Landscape Design), met today at the 5×4 site and made some planting decisions about which edible plants will go where and in what order within the 5×4 planter boxes.
While Phil Johnson (Phillip Johnson Landscapes) designed the garden with the help of Phil Withers, Sam will maintain the plants in the coming weeks and educate Ralph on how to best care for them.

Whilst on the topic of timber we met with Lew from Fisher Timber Preservation. We spoke about the different water-based pressure treatments for the hardwood, which treats hardwood to be similar to treated pine in terms of durability and weather proofing.

Whilst up in Drouin we met with Daniel Wright from our project partner ASH to discuss hardwood samples over lunch. We got a briefing on ASH in general, covering their sustainability measures and their process. We followed that up with a tour through the timber mill.

After a long drive up to Drouin, we met with Andrew and Paul from Drouin Timber and Truss about the floors, walls and windows for the 5×4 project. We were there to refine any variations to the prefabrication plans for the project, as we didn’t want pieces of the puzzle arriving on site that didn’t fit the rest of the building.
We ironed out any potential creases, discussed the installation process, and then wrapped it up with a tour of their warehouse.
Paul Stephenson from Stephenson Transport dropped in to discuss the transport schedule for Drouin West Timber and Truss. We also had to make sure the trucks would fit down our secluded little lane!
Ralph also met with Phillip Johnson from Phillip Johnson Landscapes helped brainstorm landscape ideas for the 5×4 project over a cup of tea.
Meeting held on Tuesday 6th August – GHD offices Melbourne
A range of construction assemblies were selected based on optimised thermal performance and a selection of standard and low impact materials.
Eleven different floor assembly variations and 52 different wall assembly variations were considered.
The total life cycle embodied energy of these assemblies was calculated using a comprehensive hybrid embodied energy assessment approach.
This included the energy embodied in the materials/assemblies for the initial construction of the project as well as the energy embodied in replacement materials over an estimated building life of 100 years. Average material replacement rates were used.
Assembly embodied energy figures were graphed and compared.
Major points that arose from the discussion of the embodied energy assessment results included:
• Materials with a high recycled content are preferred as they tend to have a lower embodied energy compared to virgin material alternatives
• Longevity and durability of materials needs to be considered as materials with a low embodied energy but that require frequent replacement can be a poor choice, resulting in a higher life cycle embodied energy than more durable materials
• Solid timber products are preferred over manufactured/processed timber products
• The embodied energy of some insulation products can be significant
• The embodied energy of glass can be considerable and the need for double and triple glazing systems must be balanced with the level of thermal performance they can provide
• Double-glazed spandrel panels should be avoided considering their high embodied energy
• The importance of minimising the embodied energy associated with the building’s initial construction was highlighted. Energy expended in the future (for replacement materials and building operation) is likely to be less carbon intensive than the energy presently being used in the manufacture of materials.
It is important that by minimising embodied energy that the thermal/operational performance of the building is not adversely affected. The next stage involves assessing the life cycle energy/carbon implications of a smaller range of optimised assemblies, based on the knowledge gained from this initial analysis.

How is the Project schedule traveling?
“Well, I think we are in good shape. The previous schedule would have us close to completion at this point. I thought I would get that out of the way early…
We are currently in the final stages of specifications. (more…)
