Eco Architecture: What is it?

Eco-architecture is an architectural approach that focuses on the design of energy efficient buildings that take into account the local climate, surrounding environment, water usage, human behaviour and long-term sustainability.

The term is often used interchangeably with passive solar building design, although eco architecture goes one step future by acknowledging and incorporating the needs and movement of people, nature and sustainability into building and landscape design.

During the construction phase of a building an eco architect will use materials that use less embodied energy and chemicals. This embodied energy involves the careful calculation of the carbon emission costs associated with the extraction and transportation of materials, their fabrication and assembly into the building and; ultimately, the ease and value of their recycling when the building's life is over

Well designed eco buildings complement the local ecology and can withstand extreme temperatures and weather fluctuations. They provide a sense of space where the orientation of the building maximises the use of natural light and heat emitted from the sun.

The key principles that architects take into account when designing eco buildings comprise orientation, ventilation and insulation. This entails carefully calculating the size and location of windows, walls, doors and fans to ensure good air flow and cross ventilation.

People who live and work in eco buildings report healthier relationships, are less depressed; and have an overall enhanced sense of personal wellbeing and comfort. These findings are attributed to efficient room design and layout; effective ventilation flows; heating and cooling generated via materials that store and emit thermal mass; and the smart use of natural daylight which is known to trigger the production of serotonin in people, a brain chemical that controls mood.

Eco-architecture is inter-disciplinary whereby specialists from a variety of disciplines work together to ensure buildings, communities and cities are energy and water efficient and sustainable. These specialists include architects, engineers, town planners, landscape architects, hydrologists, thermodynamic specialists, micro-biologists, physicists, sociologists, economists, property and land developers and regulators. This holistic and integrated approach takes advantage of the research, knowledge and experience collected by these professionals.

Eco-architecture is becoming increasingly popular due to constant increases in energy and water prices; diminishing supplies of natural resources; the need to become more sustainable; and the urgent requirement to change the way we live, work and build structures which complement innate human, animal and natural needs.
