An introduction to the bio-architecture movement

A lot of people have never heard of the bio-architecture movement, yet in reality, the chances are they do actually know what it is. It is just that they have heard it called something else.

What is bio-architecture?

According to Your Dictionary, bio-architecture has the following definitions:

“The design and construction of buildings and an ecologically-friendly manner.”

“The design and construction of buildings that reflect structures found in nature.”

Both are great definitions. They both explain what we mean when we talk about the bio-architecture movement.

Sustainable architecture

In this article, we are going to be looking at the second definition; that is, buildings that are designed to be as environmentally friendly as possible, or to put it another way, sustainable architecture. This style of construction is also sometimes referred to as green building.

This architectural movement has its roots in the ‘60s and ‘70s, but it has only started to go mainstream in the past couple of decades.

What makes a building green or sustainable?

There are many ways to build in an environmentally friendly way. However, most of the buildings that fall into the category of bio-architecture have one or more of the following features included in their design:

Water efficiency systems

Green buildings often include design features that enable water to be recycled; for example, using grey water to maintain the grounds or gardens or collecting rainwater and utilising it to flush the toilets. Minimising the amount of water used also falls into the water efficiency category.

A building that generates most of its own energy

Energy efficiency is one of the key features of sustainable buildings. Utilising wind and solar to generate as much of the power the occupants use as possible is a great way to minimise the environmental impact of a structure.

Increasingly, companies and residential property owners are also installing air and ground heat source pumps. Currently, these do not generate power as such; they basically move energy from one place to another. In the case of ground source heat pumps, they move warmth from the ground into a property. However, research is ongoing and it may be possible to one day to use similar devices to actually generate power.

Built-in energy saving systems

A well designed green building will also use far less energy. This means that it will be well-insulated. This ensures that heat stays in during the winter and outside the building when the weather is very hot.

Energy efficient appliances, heating and cooling systems are usually installed in these buildings. A lot of bio-architects incorporate sensors into the design of their buildings. These automatically turn off lights, screens and air-conditioning when nobody is in a room, or lowers the blinds on a hot day to keep the heat out.

Efficient waste management

In some cases, specialist waste management systems are incorporated into the design. For example, a composter in the grounds and space for recycling bins included in the design. In larger buildings, waste may be processed to produce energy or materials that can be used within it or sold on.

Making the most of natural light

Utilising natural light is another feature you usually find in green buildings. Taking this approach reduces the amount of power consumed to provide lighting for the building’s occupants. This usually means large windows, light wells and shiny surfaces to refract light throughout the building.

Wise use of outdoor spaces

Ensuring that the grounds or gardens support nature is another feature of environmentally-friendly buildings and developments. Making room for wildlife is an increasingly important part of the bio-architecture movement. It is not all about green roofs and plant walls; they do play a part, but matters like providing a pond, mature trees and areas that are left to grow wild are even more important.

Resisting the temptation to pave over or pour concrete upon large areas of the outdoor spaces is something that bio-architects do. Instead, permeable surfaces like gravel and wood chips allow paths to be created.

Sustainable materials used in the construction of the building

All of the above reduces the impact the building has on the environment when it has been finished and is in use. However, the way that it is built is what makes the biggest difference. The materials and building techniques have a far bigger impact on how environmentally friendly the finished property is.

The use of recycled materials

The recycled materials used in sustainable architecture come in two main forms. Firstly, materials that have been used elsewhere can be employed, such as second-hand tiles, wood, fixtures and fittings. Demand for this type of recycled building materials is on the increase. As a result, the architectural salvage industry is thriving

Using building materials that have been made from waste products is the other way in which architects are able to build in a sustainable way. New types of recycled building materials are becoming available. It is now possible to create a building using mostly construction materials that are primarily made from recycled materials.

Products made from waste wood are especially easy to get hold of and use. These includes flooring and planks made from compressed waste wood chips. Artis walling is a great example of this style of building material.

It is also now possible to buy tiles made from recycled plastic and countertops made from waste glass and stone. A lot of the steel that is used in modern buildings is also recycled.

The use of sustainable building materials

The other way architects reduce their carbon footprint is using building products that are made from sustainable materials. This means materials like fast-growing wood, bamboo, hemp and cork. All of these can be harvested and replaced within a few years, or sometimes months. For residential buildings, straw bales and green insulation products like wool are also viable sustainable building materials.

Using locally produced construction materials

Using locally sourced building materials is another practice that is widely used within the bio-architecture movement. The fewer miles the materials have travelled, the less pollution has been produced.

So ,now you have a good idea of what makes a building green. Stay tuned, as we’ll return to this subject at a later date and provide you with the best examples of bio-architecture from across the world.
