Performance Based Building Design

It Just Makes Sense

Our Vision

To Improve the Quality of Australian Homes

Through Smarter Design

Without Increasing Costs

Our Solutions Are

Liveable

Our homes are comfortable and healthy to live in, cost less to run and maintain and look beautiful.

Authentic

We are genuine in our desire to provide the best performing home design solution for you.

Bespoke

Our designs are tailored specifically for you, your location and budget.

Why Design with us?

We have the skills and design systems to provide you with a superior performing house, we strive for Passive House / Passivhaus standard however can tailor accordingly.

Through increased performance you will be more comfortable, cut energy bills, breathe cleaner air and save on house maintenance.

Our designs are architecturally beautiful but also focused on build-ability. We analyse each component of design and where able find simpler and cheaper solutions to achieve the same outcome.

Common Misconceptions

‘The most common misconception about Passive House is adherence to the stated reference values and that meeting these criteria are required for certification, which states that triple glazed windows are required; in most areas of Australia, thermally broken double glazed windows are sufficient. These reference values apply to a Central European (read Germany) cool moderate climate that enable a constant temperature within the house of 20deg. The beauty of the performance based system is that it is relevant to the climate of the location of your house and that the criteria may be relaxed to suit your situation.’

‘Another common misconception is that Passive Houses need to be shut up all the time to work. The goal of a passive house is to reduce the energy consumption required to maintain the house at a comfortable temperature. If the weather is fine enough to have windows and doors open then by all means keep them open. If it is cold or hot outside though, the house should be shut up in order to work effectively in maintaining a comfortable temperature. Fresh filtered air is provide through a HRV system which provides a much healthier environment than when you use an air conditioner or heater in a closed house.’

#nomorerulesofthumb #PHPP for standard design process. We have commenced one of our most significant commissions in the last week. The clients have agreed to have their design modelled with the #PassiveHouse Planning Package as part of the normal design process. Whilst the goal is to reach the Passive House standard at the very least our clients will know how their house will perform and hence make informed decisions about which products to use in their house. We will update the process of this design to keep everyone in the loop. ... See MoreSee Less

New Concept - This project is another variation on the classic beachside / country theme. It is a home for three generations on a great block near Moonee Beach. It has not been without challenges in the design but we think that it is a great result. Let us know what you think ... See MoreSee Less

#PHPP will save you money - Passive House is gaining traction in Australia, it just makes sense. In a lot of cases it is being client driven through research online. There are a couple of pitfalls to be aware of before super-insulating your house and placing an order for triple-glazed windows. The main pitfall people fall into is not having their project modelled in PHPP (Passive House Planning Package). Passive House is a performance based standard and NOT a product based standard. PHPP allows your project to be optimised in every way - insulation, glazing and heat recovery ventilation. If you don't intend to get you house certified, PHPP can still be used to model for your desired indoor conditions and accordingly optimised. Airtightness is a non-negotiable but everything else can be optimised. There are two key reasons for the optimisation

1. Ensuring the heating and cooling loads are accurate and known.

2. Minimising waste - materials and money

We have heard of two cases recently where clients have been advised by suppliers to buy triple glazed windows for Sydney. This is totally unnecessary in our climate. The attached image is from the Passivhaus Designers Manual which details the glazing required for various climates. Melbourne is a warm temperate climate and Sydney is warm temperate to warm. Double glazing with thermally broken frames are more than sufficient in just about all of Australia.

In another case a client was advised that R10 was the required rating for the walls of the house. This led the builder to having to build a double framed wall and place extra insulation in the wall. This is a waste of material and a waste of money. For our project which is just about to start construction the walls have a R-value of 2.7. The project meets Passive House Standard.

The typical cost of PHPP modelling for a single dwelling is between $3000-$5000. Whilst this might sound expensive, modelling has shown for our Toowoomba project that we can heat the house with 2 towel rail heaters and cool the entire house with two 2kW split systems with the least amount of insulation to achieve Passive House Standard. For the project mentioned in Sydney, upwards of conservatively $10000-$20000 could have been saved by modelling accurately. In another project for which has yet to be modelled the client has been advised to put a large ducted heating and cooling air-conditioning system in a project in Sydney as well as underfloor heating in all bathrooms. Chances are if this project had been correctly modelled the heating system could have been negated, the cooling system reduced and the client saved greater than $10K.

In the same way you would not ask the engineer to guesstimate the amount of reinforcing in the foundations your designer/builder shouldn't guesstimate the level of insulation or glazing with the proper calculations.

A long one I know but if you want to build a low energy house and don't want to waste money - don't guess.

We are happy to take calls for education purposes at anytime.
