Baseline Analysis of Banksia House:
EXECUTIVE SUMMARY of
LBC PETALS vs. BASELINE BANKSIA HOUSE:
●
ENERGY - Suggested PV system
does not supply 105% of required electricity usage for a home of 4 people. - Thermal comfort is partially considered through the use of cavity brick walls on both east and west facades, along with the deployment of operable windows for natural cross ventilation. - Sloped roof structure does not optimize heat displacement of home interior. - The use of skylight and cleselstory are not optimized.
WATER - The implementation of a water tank is indicated on the north-east side of home, but is not full realized and integrated within the design. - Roof area does not provide sufficient water catchment for the household of 4 (given daily water use of 293L). - All pavement surfaces should be water -permeable. - Does not indicate the recycling or reuse of greywater. - The implementation of Water Efficient appliances cannot be comprehended within baseline design.
MATERIALS - Materials deployed such as timber fascia, steel beam, and compressed lining are generic and does not suggest the support of local production and businesses. - The prohibition of red-list material is not stated. - Design with the end in mind can be comprehended through light-frame construction, but can be further improved. - Baseline design naturally does does not propose the utilization of salvaged materials from old home.
PLACE
BEAUTY
HEALTH
- Generic plan naturally lacks a sense of place and inter-relation to natural habitats and ecosystems.
- Baseline home does not suggest the uplift of human spirit: the protruding solar panels from all sides of the home can be deemed as an eye sore to the community.
- Generic plan does not suggest the interaction between human and nature as encouraged by the Access to Nature imperative.
- Exceptional Ratio between outdoor green area and indoor area. 350sqm (outdoor) to 194sqm (built footprint) Ratio = 1:18 - Baseline design does not suggest bike storage nor electric charging station for non carbon-dependent vehicles.
- Baseline elevations does not comply with the characteristic of the neighborhood. - Lacks variation of spatial qualities: refuge, prospect, etc.., - Generic plan does not foster a connection to natural habitats, eco-social, nor connect to the prevailing culture of the area.
- Further improvements can be made for Indoor Environment Quality and acoustic comfort, as also briefly mentioned in the material petal. - Openable windows and sliding doors offers exceptional ventilation, but can be further improved for targeted areas like the kitchen.
EQUITY - Inclusion imperative - Generic plan does not suggest the donation of 0.05% of house expense to a good cause within the community. - Universal access is achieved as the single storey house does not block sunlight access and fresh air access to the neighbouring houses, given its lower rise.
The recycling of black water to achieve drinkable quality is difficult to attain. Consider how to segregate potable and non-potable water efficiently.

Construction Water Stop: install a ‘water stop’ along the slab base between the reinforcing bars Complete wall construction core filling the block wall cavity, with aggregation to avoid air cavities. Membrane Preparation: Install quality caulking compound, Sikaflex PRO. Smoothing the finished joint and removing the masking tape.Apply either Microl Acrylic Primer or 1 part FLEXIPRO to 2 parts water, as a primer coat. Work the primer coat into the surface with a generous brush, soft broom or roller system. Membrane Tanking: Install a ‘Bond Breaker’ system to the joints between the slab and first course of blocks. Apply the first coat of waterproofing membrane with a brush, roller or soft broom with a coverage thickness between 0.5mm to 1mm.Apply a second coat of waterproofing membrane with a coverage thickness between 0.5mm to 1mm.
4.
Penetrations Treatment: Install the caulking, Sikflex PRO to provide flexible bonding between the two materials. • Complete the membrane application by installing a ‘bond breaker’ system.
5.
Protection and Drainage: Install plastic sheeting or ‘bubble’ rolls against the membrane prior to backfill. • Install FLOCELL sheets, covered with FILTERWRAP geo-fabric against the membrane prior to backfill. This method also helps the water get to the drainage system more efficiently.

to retain stormwater and produce food at the same time capture and filer urban stormwater using sandy soils and drought-tolerant plants choice of soils: loamy sand or substrate & potting mix potting mix produce bigger plants, greater yield tomato yield was unaffected by treatment bean mix greatest by potting mix beetroot yield is greatest with sub-surface watering parsley yield is greatest with surface watering choice of stormwater application: ‘sub-surface’ and ‘surface’ watering
Engineered garden beds with sandy soils and hardy perennial plants which capture and treat stormwater that runs off roofs and impermeable surfaces such as roads -
improve plant available water, plant growth and stormwater retention and improve water quality outcomes
20% organic matter (composted food or green waste) to raingarden sand-based substrates improves hydraulic function, resulting in optimal saturated hydraulic flow and greater retention of stormwater runoff.

The pivoting landscape of the site provides the perfect opportunity to deploy a wetland frogpond:
Lizards help maintain minimal insect and pests as they consume it for food.
The city of Boroondara is blessed with a variety of beautfiul birds and parrots - not only that they are attractive to the eye, they also sing for you (free of charge).
Initial issue: area is towards the south of site - too sunny for frogs and tadpoles.
Consider: Lizards / reptiles are cold-blooded - they need area of full sun.
Consider: birds require areas for them to hideout in cases of escaping from cats or dogs.
Implementation: - Obtain water plants such as water plantain, etc.., providing food and protection and shade for tadpoles.
Implementation: - Placement and orientation of lizard lounge areas must received full-direct sunlight.
- Tall native grass species such as kangaroo grass and tussock grass is planted to provide additional shading and shelter for frogs - it also helps oxygenate the still-water body.
- Plants should be short, sparse, and does not develop into a full canopy: tussock grass & wallaby grass are used for these areas.
Implementation: - Implementation of indigenous trees with dense canopies such as yellow fun or brush box, proving a variety of insects on which to feast. - Native Shrubs such as river bottle brush, prickly currant bush, are essential. Many smaller birds will weave through these safe havens while searching for food. Some small birds will nest only in bushes • Native grasses such as the tussock grass, host a staggering amount of insect life. These insects might be hard to extract but they provide a constant supply of nutritious food.

03 REFLECT: Recap of Meeting TEKA: Yume, how has this unit / group project been to you? YUME: I didn’t expect this unit to be this engaging with various elements to understand the design principles toward sustainable architecture. For sure, it wasn’t always easy to process all the learnings through the semester, but with the actual scenario given, I was able to think deeply enough how to achieve this in a practical way. It was a good opportunity for me to get to know analytical tools to quantitatively and qualitatively test our proposed solutions and justify design decisions. How about you? When I first read the course’s outline I genuinely did not expect us to get to be this in depth about the impact of architecture towards the environment. With all sugar-coating aside, I will definitely refer to the knowledge I have accumulated within this course within my career in the future. I came to realize that sustainable design does not have to be tacky, boring, or ugly. Which petal was your favorite? I especially appreciate the petals of health, beauty and equity. As each is integrated in a complex way, I thought it was crucial for us to think in a flexible way. I really appreciate this opportunity to learn about the concept of biophilia, I would definitely have this concept in my mind for future projects. What would you do differently next time? Of course, all the mistakes has been a good learning experience. But, I do wish that our initial proposals were more cohesive with our latest proposal - as towards the end it became somewhat difficult to align the ideas and thoughts. I guess, it is a part of the learning curve. I am happy with our visuals. I think we were quite adventurous with the colors.
That’s true... and I agree with you. It isn't always easy to visualize thoughts in our heads onto paper, but definitely enables us to think more in an engaging way. I will keep sketching for sure. Thank you for all your hard work!
Thank you, for your hard work Yume!

To Conclude: Admittedly, this project has been extremely challenging for us - every week has brought new challenges and content for us to digest - notably, as the weeks progress, the intensity simultaneously becomes more difficult as we are expected to do the analysis based on our cumulative understanding of the LBC Principles. This unit has provided an opportunity for us to reflect upon design fitting for climate - not only for Melbourne - but for any parts of the world that we set out to design for. Through weekly resources and topics, our knowledge of sustainable, energy-efficient, design - which is meant to correlate with beauty and well-being of its occupant as well - opts for a clear understanding and creates a mental-imprint of how to correctly design as architects. Sustainable design fundamentals, strategies, and means of implementation will continue to be used by us within our career as architects of the modern world. It is not difficult to fathom how relevant the issues of sustainable design within the near future will be - transforming all industries - not only architecture, but the livelihood of the whole humanity. Patricia, thank you for your encouragement and effort. You have always pushed us to strive for every opportunity for us to learn and acquire more understanding.
