The Benefits of Sustainable Design in Commercial Architecture

As people across the world become more aware of our impact on the environment and commit to reducing it, they’re looking to businesses in all industries to keep up. As we spend a large percentage of our time in our homes or other buildings, and buildings make up 30% of all greenhouse gas emissions, it makes sense that a lot of the burden falls on architects.

Sustainable architecture refers to a focus on reducing the environmental impact of a building through energy efficiency, water conservation, responsible material use and integration with the surrounding ecosystem. Also referred to as eco-architecture or green architecture, examples include systems like rainwater harvesting and green roofs that give a little of the building back to nature to catch carbon and help actively contribute to the environment.

This style of architecture can be used in residential and commercial projects, but is particularly popular in commercial buildings like offices to offset their carbon footprint. A prime real-world example is The Bullitt Center in Seattle, which advertises itself as ‘the greenest commercial building in the world’. It was designed to have a 250-year lifespan, showing a commitment to durability. Solar panels generate all the energy it uses each year, and it catches and purifies rainwater for all its water needs, so it’s net-zero for both water and energy. While this lofty goal isn’t possible for all buildings, it shows an ideal and can help inspire other architects.

The main benefits of sustainable architecture include:

• Reduced environmental impact through lower carbon footprint, energy use, and waste creation. By using nontoxic and/or recycled materials, these buildings also reduce water and air pollution.
• Enhanced biodiversity by incorporating and protecting the nature around the building, which helps protect species and can inspire further green actions.
• Greater resilience to natural disasters like floods, earthquakes, and fires, which is increasingly important as climate change continues to worsen.

How These Designs Improve the Overall Well-being of Occupants

Architecture is often focused on design and visual impact, which is, of course, an important part of any building. There’s now growing evidence that we need to be placing ‘indoor climate’ as a higher priority. Poor airflow inside has been shown to lead to respiratory issues. Excess humidity leads to the growth of mould spores, which can make the problem worse.

Prioritising natural light through large, well-placed windows, especially in high-humidity areas like bathrooms and kitchens, can help improve airflow and therefore occupant health. The UV rays through the window can help to kill mould spores too.

Natural light in buildings provides significant health benefits:

• Improved workplace performance with better focus, reduced eye strain, and healthier circadian rhythms leading to better sleep.
• Enhanced mental and physical health through increased serotonin (boosting mood, memory, and appetite regulation) and Vitamin D production (supporting bone and immune system health).

Reducing the emissions from a building and those used in creating it reduces pollution and improves air quality of the area, so you are benefiting more than just the occupants of the building you design. The green housing industry is a growing business so by supporting it you’re helping to create jobs and therefore support your local economy which is helpful for everyone in the area.

It’s clear then that when you want good emotional and physical health and improved concentration at work, sustainable designs are the way to go.

Cost & Brand Reputation Benefits

Sustainable material options can be a higher cost initially, especially if using recycled options, as the process of recycling can be costly. There is less wastage, though, so construction costs can be reduced slightly. Also, homes with natural light and other sustainable features, such as solar panels for creating energy, have a higher resale value, and demand for them is increasing, so they’ll sell easily.

Financial advantages of sustainable buildings:

• Lower ongoing costs as sustainable materials require less maintenance over time and generate reduced energy bills through self-produced power and improved efficiency.
• Higher property values with sustainable features making buildings more attractive to buyers and tenants, particularly businesses looking to reduce monthly outgoings.

Your business will also benefit from investing in sustainable architecture practices. If you’re a contractor or builder, customers and architects who have a focus on sustainability will seek you out once they know you’re prioritising those projects. There are sometimes tax or grant incentives for building sustainable buildings, so it’s worth looking into this.

If you’re a business owner, customers will be impressed by you showing your commitment to your green targets by choosing to occupy a sustainable building. Customers are very conscious of so-called ‘green washing’ where companies overestimate their policies for delivering climate change, so seeing you take clear action will boost your business.
