architectural design for the future

At Haviland Architects we embrace passive solar design principles and other environmental initiatives to achieve good designt that positively responds to the site constraints to produce a living environment that is stunning, as well as healthy and energy efficient.  Our designs all undergo a thorough sustainable building index analysis to comply with government standards.

passive solar energy principles

These principles take advantage of the Australian climate to reduce the heating and cooling requirements in your new home and to help maintain a comfortable temperature all year round.

Designing your new home along these principles, ensures lower energy bills and reduced greenhouse gas emissions for the life of your home.

Passive solar energy design includes:

  • Orientation of your home, windows and doors in relation to the sun and to cooling breezes.
  • Using building materials with a high thermal mass, such as concrete, bricks and tiles, which have a high heat storage capacity, making significant cost savings on heating and cooling.
  • Effective shading from roofs, eaves, overhangs, awnings, shutters, pergolas and plantings, which reduce up to 90% of the summer sun’s heat in your home, whilst not blocking the warming winter sun.
  • Window glazing can be a major source of both heat loss in winter and heat gain in summer. These problems can be overcome by considering the placement, orientation and size of your windows and type of glazing.
  • Insulation is an important factor in the thermal regulation of your home, helping to maintain a comfortable temperature, regardless of the season.

energy efficiency in your home

Energy conservation can include: hot water systems, air-conditioning, lighting, home entertainment, computers, security systems, home automation, and appliances.

At Haviland Architects we use inspired designs and energy efficient technologies, such as solar, to focus on energy conservation, reducing both your energy demands and your costs.

water efficiency in your home

We consider the water usage in your kitchen, shower, toilet and laundry, install water efficient devices, help to conserve fresh water in your home and save you money. Rainwater tanks also help to reduce mains water costs, as well as the reuse of both grey water (from taps, basins and showers) and black water (from toilets).

You can use grey water to reduce the use of mains water in your garden (if it is low in phosphorous and sodium) and when treated, it can be used in toilets and the laundry. [This re-use may be limited in some Council areas.]

responsible building materials

All building materials have some environmental impact.  However with a careful selection of materials, the carbon footprint can be reduced and subsequently the environmental cost. For example, we use as many renewable materials as possible in your new home, renovate and redesign where necessary, use recycled materials and through waste management schemes avoid unnecessary wastage. Low maintenance materials that are durable and long lasting, sustainable resources and eco-friendly products are all considered when we design an environmentally friendly home.

one sydney council’s green initiatives

Willoughby City Council on Sydney’s lower north shore has initiated an environment and sustainability program, called ‘ClimateClever’, which aims to educate the public about sustainability at home. They have several downloadable PDFs on their website that provide guidance on saving water and energy, efficient thermal insulation in your home, solar energy, renewable and low resource building materials, star rated energy-saving products and tips on living a greener life.

At Haviland Architects, we use all of our experience, knowledge and talents to ensure that your home is well designed, appropriately insulated and environmentally friendly. The flow on effect can result in reduced energy bills, greenhouse gas emissions minimised and your home will be comfortable, stylish and energy efficient.
