Eco Friendly


Our Building Consultants are passionatly devoted to developing and building homes that meet and in many cases exceed your expectations 

Energy efficient / Eco friendly homes just dont happen, these homes are carefully planned and considered over a number of conversations and site meetings.

Reducing the costs of living in your new home, creating a comfortable interior thermal environment  while delivering a financially viable building option is our challenge and our design and development approach has allowed many of our clients to achive these goals and enjoy living in amazing environmentally friendly homes

You dont have to reinvent the wheel or build a home that looks like a spaceship to achieve an energy efficient eco friendly home, certainly if you are planning to have an architecturally designed and specified home developed with Bryan and Petersen or bring your plan we are equally excited to produce extremely effective outcomes for you too, many of our plans we offer in our range,  planned on the site correctly will produce a great outcome for you 

Bryan and Petersens building consultants will approach each project afresh, we will not approach your project with fixed ideas, our ambition is to design and devolop the home to fit the context, design brief and budget

Your building consultant will when developing eco friendly/ energy efficient homes look at many of the below listed options and address as many as possible during the process with you according to your level project ambition 


  • Site assessment
  • Topography, slope etc
  • Establish true  or "solar" North
  • Orientation, good orientation will reduce the load requirement on auxiliary heating and cooling reducing your homes energy bills
  • Climate conditions (Zoning) the core 2 climate conditions we build within are COOL TEMPERATE (includes cold alpine) and TEMPERATE 
  • Shadowing
  • Overlooking
  • Client requirements (space , bedrooms , general design brief etc)
  • Material selection
  • Style 
  • Ongoing maintenance required
  • Achitectural design influence
  • Glazing and window framing options
  • Wall types
  • Insulation options
  • Thermal mass options and placement
  • Ventilation / cross flow ventilation
  • Shading devices both adjustable and fixed options
  • Roof cavity ventilation
Draft reduction
  • Weather proofing and seals to doors , gaps, cracks etc
  • Draft stoppers fitted to exhaust fans etc

Heating and Cooling
  • careful consideration of the vast aray of options available to suit the site and client requirements
  • Our intention is to promote passive heating and cooling measures and minimise the reliance on auxiliary heating and cooling systems where possible
  • we have many years of experience with some of the following systems
  • Hydronic inslab and/or wall radiators
  • geothermal heating and cooling
  • high velocity heating and cooling from varied boost sytems
  • high efficiency gas central heating
  • high efficiency refrigerated cooling 
  • LED lighting
  • Fluorescent lighting
  • low wattage solutions
  • Consider using solar lighting for outdoor spaces
  • careful placement
  • Use well designed windows
Electrical appliances
  • Electrical appliances can acount for approximately 25% of household energy consumption
  • When purchasing white goods (fridges, freezers, washing machines, dishwashers and clothes dryers) look for the star ratings
  • The higher the star rating the lower the long term cost of running the item
  • Turn electrical appliances that dont need to be running off when not in use 
  • Standby energy use can account for upto 10% of household energy use
Solar power
  • Our team of electricians have assisted with many solar power installations ranging from small 1kW to larger 10kW roof mounted systems 
  • Full off grid power generation systems have been installed by our electricians and are successfully working 
  • Our electricians can assist with the range of alternative options available
Hotwater Systems
  • Choose the most efficient hotwater system and the best energy source to meet your families needs
  • Solar, gas and electric heatpumps produce far fewer greenhouse emissions than conventional electric storage systems
  • Solar boosted hot water systems are apart of nearly every roof these days however there are many different systems available that may suit different site conditions and family demands
  • Solar and Heat pump hot water systems will contribute to sizable reduced energy household bills
  • assess the star rating of the hotwater system the higher the star rating the more energy efficient and the lower its comparative enrgy consumption 

Landscape Consideration
  • deciduous trees for shading
  • Drought proofing your landscape

Room Zoning
  • Zoning of living spaces allows more effective heating reducing household bills
Water Use
  • Reducing water demand
  • Rainwater harvesting
  • On-site waste water reuse
  • Storm water management
  • Outdoor water use
  • Selecting the exterior colours also have an impact on the thermal performance of your home
