Why is Sustainable Architecture Important?
The construction industry is one of the major contributors to global carbon emissions, resulting in 40% of total emissions worldwide. The leading factor to these emissions is generated from energy consumption required throughout the lifecycle of the building. In this article we will explore the key fundamentals of sustainable architecture, and various architectural design principles that can be incorporated into any design regardless of size or cost. As architects we are at the forefront of the built environment and it’s important that we implement these methodologies, designing for future generations and not for the here and now.
EXISTING ENVIRONMENT
Sustainable architecture explores innovative architectural solutions to engage harmoniously with the site and to avoid excessive damage to the natural landscape. Some alternatives of working with the natural environment might include embedding the structure into the landscape, raising it above on stilts, incorporating existing vegetation into the design (instead of removing them), or even repurposing disposed materials. Remaining sensitive to the natural surrounding and minimising the amount of destruction, can create a strong ‘sense of place’ and a positive contribution to the local environment.
SOLAR PASSIVE DESIGN
One of the largest contributing factors of energy expenditure in residential projects is from mechanical heating and cooling throughout the life of the building. Solar passive design principles rely on the natural resources, specific to the site, determining the most suitable layout and positioning of the project. Orientated to coordinate with the sun, wind, and shade, solar passive design controls how the natural elements will affect the building envelope and determine whether there is need for additional heating and/or cooling systems. The additional energy consumption required can be offset by way of solar panels and batteries.
CARBON NEUTRAL FOOTPRINT
The life cycle of a building takes into account the amount of energy used over the course of its life, from manufacturing of materials, construction, operation and its eventual demolition. Embodied carbon refers to the energy required throughout the production, transport, and installation of the materials. Operational carbon refers to the emissions associated with the functions of the building, including heating, cooling, ventilation, water usage and waste disposal. To achieve a carbon neutral footprint, the embodied energy should balance out the operation energy saved throughout the life span of the building.

MATERIALITY
Materiality is tied in closely with the embodied energy of a building and its carbon footprint. It is important to have an understanding of the materials being used, how they are made and determine whether they are the right option for the project. Sustainable architecture minimises the negative environmental influences and waste of resources, limits demolition and unnecessary product consumption. Sourcing recyclable and local materials is a smart investment that can significantly save on maintenance costs over the life cycle of a building.
RESTRAINT
Bigger is not always better. Less square meterage of materials equates to a reduced carbon footprint. With the current global energy and climate crisis, it is crucial more so than ever that as a society we revaluate the manner, in which we live. It is important to be mindful as to whether we need it or just simply want it? A smart and efficient design can still achieve the desired outcome whilst utilising minimal resources and reduces its carbon footprint. The longevity of sustainable architecture is the result of smart architectural design, high quality construction, and durable materiality.
HEALTH AND WELLBEING
There is an inherent biological connection between humankind and nature, which has subsequent physical and psychological health benefits. This connection is noticeable when several intangible qualities such as natural light, fresh air, visual sight lines, and thermal comfort are incorporated into a building. It can also establish a healthy atmosphere by means of natural, toxin-free materials, and the presence of nature within a space. Perth architects are conscious of the health and wellbeing of both the planet and its inhabitants, and embrace a holistic approach, to ensure harmony between these two realms.
Sustainable architecture is the practice of creating buildings which make as little impact on the natural environment as possible by reducing the negative effects caused by the lifecycle of a building. These practices can help strengthen community bonds, improve quality of life and provide hope for a better future. Environmentally sustainable practices can help protect natural resources, mitigate and adapt to climate change and promote biodiversity. As we become more aware of the world around us and the impact we have on nature, sustainable design alternatives are becoming more common place. Perth architects are constantly exploring innovative architectural solutions ensuring the built and natural environments can intermingle harmoniously, enabling a more promising future.
