Did you know that the idea of green sustainable buildings dates back to the 1970s? For a long time it was only a theory that a building could conceivably be net zero emission and actually produce more energy than it consumes. Today it can happen because of the array of technology that is available, as well as the various standards and certifications. Whether it is homes, commercial architecture, or other structures, they can be green and sustainable.

A great case study

The fantastic thing today is there are plenty of projects around the world that can inspire the creation of green architecture. If you look specifically at commercial properties, the Bullitt Center in Seattle, Washington, US, is notable. In fact, it is one of the most popular case studies for this kind of building.

Impressively, some say the building was the greenest commercial building in the world in 2013. Two years later it got certification as a “Living Building”.

There are some really impressive details about the building. Firstly, it has a roof full of solar panels. There are 575 in a massive 14,000 sq/ft system. They generate a huge amount of electricity every year. In fact, in 2016 it generated more than 30% surplus energy. There are times when it does draw more energy from the grid because of the cold weather, but over the course of the year it generally is net positive.

Bullitt Center is also effective when it comes to water use, an increasingly crucial factor for commercial architecture. It harvests rainwater and manages grey water. A series of treatments, filtration, and disinfection ensures the it can be used for toilets. This minimises how much water the building consumes. Originally it had compostable toilets too, but in 2021 a low water vacuum system replaced them.

The heating system is interesting too. There are 26 geothermal wells, each reaching down 120m. The depth means they are a stable 13 degrees Celsius. As a result, they can keep the building warm in colder months but won’t contribute to overheating in the summers.

The windows and operable shades also help to maintain comfortable temperatures inside the property. There is triple glazing to reduce thermal bridging.

Today

Over a decade after it was finished, Bullitt Center is an impressive standard for green commercial design. The fact it is estimated to have a 250 year life cycle is fantastic. If it maintains its performance levels, it will have a massive positive impact rather than harming the environment.

Speak to us about commercial architecture

At Coffey Architects we can always love to see green, sustainable designs. They show what is possible when building with the environment in mind. The results can be excellent, just like the case above. It can ensure properties have longevity and a net positive impact rather than a negative one.

If you have this kind of project in mind, especially commercial architecture, speak to us. We’re confident we can help you create the most impressive design, with the right materials as well as effective use of green technology.
