Is it time to move beyond the limits of ‘built environment’ thinking?

The constructed world around us provides the stage for our daily life. The term “built environment” is in the past tense, describing a scenario after the fact. What does it actually mean beyond the obvious connotation of buildings and parks?

Yet when we pay respect at a formal occasion to the traditional peoples of Australia it is generally referred to as Acknowledgement of Country. Here we acknowledge the environment (country) first and then the custodians of it.

Today we are at pains to integrate environmental concerns into our building efforts. We are discussing how to meet climate targets, reduce heat island effects and limit the impacts of the built environs, which have harmed our planet. The term built environment seem to come from a time when we felt the need to dominate nature; now we are desperately trying to work with it.

Viewed from a different perspective, the built environment is a constructed historical record of how societies developed and applied their technical skills to express the culture of their time. It is all the infrastructure, power grids, water pipelines, dams, refineries, cargo terminals and industrial manufacturing sites that enable our urban existence.

The term also speaks about the expertise of the various trades and the craftsmen involved. But not so much about the professions that negotiate the abstract world of policies, council guidelines, building codes and the laws – not only of physics but also of the legal framework of contracts and workers’ rights. Together it creates visible structures that allow for comfortable living, business activities and transport networks.

Looking beyond buildings

The term built environment in an academic setting describes a suite of disciplines engaged in studying and therefore aiming to improve it. The late architect Col James “made housing a verb”. He did so not only to reflect the human agency involved in the processes but to provide a more equitable and just living environment for people who don’t have the means to get their own architect to design a dream home for a cool US$2 billion.

The built environment looks like the material world conceived by planners, designed by architects and constructed by builders and labourers. Yet, if we look closer, we can see that these structures are only one part of the equation. These build things (buildings) on their own can not simply be populated by people. People would have nothing to do in these buildings were it not be for the fixtures, fittings, furnishings and products within them.

These elements enable and activate these environments and make them usable and productive for their intended purposes. If the products within them fail they can make buildings harmful.

These products are not so much built in the traditional sense, but are mass-produced high-volume items. From window frames to light switches, phones and furniture, these are products conceived, designed and specified by professionals like industrial designers. They form an integral part of the built environment.

Even buildings themselves are not built in the traditional sense anymore, but are more and more the result of complex manufacturing processes. Project managers and builders are orchestrating a vast range of pre-manufactured items, which they assemble skilfully into an environment fit for human use.

If we are at a hospital, train station or playground, these environments are populated with equipment that speaks explicitly to the use of the space. In hospitals we see kidney analysis machines, hospital beds and infusion stands. The station has signage, trains and turnstiles. And at the playground the equipment lets us play and have fun.

Without these things these places wouldn’t be what they are. They could not perform the function that is their reason for being. Therefore it is the things in these environments that give them their meaning and function, because they enable it.

Our environment is and always has been integrated with products that help us with access to the services and infrastructure available at the time.

If we look closely at these two words they tell a hidden story. We have built, which is made, created and manufactured, and environment, which can be either human-made or natural. The term links the made world with our natural world. It describes the world we made so far. But the two are separated.

The interesting thing is that the made world, the one we created, is mentioned first. The setting it creates or into which the buildings are placed comes second. There is a hierarchy here that relegates the environment to second place.

Urban Runoff and Water Sustainability in Urban Design

The issue of conserving our environment is a complex one. While reducing our material usage, reusing what already exists and recycling other products are all valuable steps towards reducing the impacts of climate change, they cannot be the only strategies adopted in an integrated approach.

Sustainability is not just a matter of products. A holistic approach must also encompass how the built environment responds to its context and to its inherent natural processes. This is more important than ever, as extreme weather events become more frequent, placing extra stress on – and accelerating the degradation of – both our natural and built environments.

Australia has long been known for its capricious weather and extreme climate conditions, ranging from flash floods to extreme droughts in a seemingly narrow space of time. These extreme weather events have been exacerbated as a result of climate change, and have presented significant problems to the natural environment.

When heavy rainfall is paired with the rapid growth of our urban environments, one of the issues that results is urban runoff. Rain travels from roofs to gardens, footpaths, roads and carparks before landing in our stormwater network. On its way into the ocean, stormwater inevitably collects a number of contaminants which, in their final resting place, end up upsetting the delicate nutrient balance of our natural water table.

The harmful chemicals and substances that find their way into our stormwater system comes from any number of places. For instance, nitrogen and phosphorous from fertilisers, heavy metals such as zinc and lead from our roads, in addition to your standard-issue garbage and detritus. A city such as Sydney sheds 500 billion litres of stormwater into the ocean per annum – the equivalent of the water within Sydney Harbour – which has significant consequences for the water networks that sustain our natural ecosystems. Not to mention our drinking supply.

In order to tackle this issue, Australia’s federal, state and territory governments have sought to adopt Water Sensitive Urban Design (WSUD) practices. Some of these include increasing natural water infiltration, promoting organic alternatives to fertilisers, herbicides and pesticides, and slowing the discharge of stormwater runoff. Increasing the length of time that stormwater takes to reach natural waterways allows for a longer filtration process, to remove the harmful pollutants and foreign bodies picked up in the initial stages of its development.
