Passive Design

A sustainable home starts with a passive design to deliver high performance and comfort for the occupants during the life of the home.

In a cool temperate climate we incorporate the following basic elements:

  • Orientation to maximize free heating from the sun
  • Optimal insulation to limit thermal bridging; especially through exterior walls, floors and ceilings
  • Design for natural ventilation; fresh air is free and more beneficial to health
  • Energy efficient products to reduce running costs
  • Thermal mass is used to absorb and store energy during the day to be released at night. Thermal mass can be bricks (various), stone, aerated concrete, concrete tilt up panels or ceramic tiles. Thermal mass should not be substituted for insulation or used where it can be a heat drain. Thermal mass can, in the wrong place, suck heat out of a room in the colder months if it doesn’t benefit from sun exposure.
  • Thermal insulation in walls, ceilings and under floor coupled with drapes and pelmets over windows to reduce heat loss in cool months acts like a warm blanket in winter and insulates to reduce heat gain in summer.
  • Thermal bridging requires planning and designing to reduce heat loss through leakage points such as walls and ceilings, ducting and vents, doors and windows and plumbing and electrical penetrations such as light fittings and pipework.
  • Aim for windows to thermal mass ratios of 15-20%; too many windows in the wrong place or without shading in summer can cause discomfort and be less beneficial.
  • North facing double glazed windows preferably timber or timber/aluminium reduce heat loss during winter and reduce noise pollution in city and suburban environments.
  • Windows with an optimum opening for ventilation and air circulation such as casement provide better function and air flow over double hung and sliding windows. In some instances casement windows allow direction of air flow to where you need it.

Designing a home in a hot climate takes on similar elements however the main focus is on more shading and protection from the hot sun and natural cross ventilation.

Passive design requires orientation of the home on the site with a floor plan providing livings rooms with beneficial winter sun in cooler climates and sufficient shade in summer using roof overhang, veranda's, wider eaves or added options to ensure the sun has less penetration on hot summer days. By using products that work with you to use what nature provides for free is the key to creating a sustainable home. The next step on the path to sustainability is healthy products and wicked thinking. It's the WICKED knowledge we provide that makes all the difference.

Benefits from living in a healthy passive solar designed home include:

  • Homes are comfortable and pleasant to live in all year round.
  • Homes are energy efficient and save you money with lower power bills for the life of the home.
  • A passive, well designed home reduces your dependence on non-renewable energy sources and results in lower emissions.

The planning process starts with your location to identify hidden issues detrimental to health and soil testing to determine the specific engineering required for foundations and support structure.

The design stage starts with a questionnaire to determine needs vs wants. Material selection is based on your highest priorities and the budget you have in mind. Your home needs to meet your existing and future requirements which is why we discuss the benefits of passive design, energy efficiency, maintenance, landscaping and completion of the entire project to meet sustainability requirements for health, wealth and lifetime value.

Placement of thermal mass heated by the sun is a critical element of a passive designed home. Providing cost effective thermal mass in a home is easily incorporated at design stage with a variety of options available.

Passive designed homes are good for our planet and future finances however incorporating healthier building options is a must for future health of our children and our children’s children.
