The Greenest Buildings in the World? – the Living Building Challenge

George Monbiot, via his book ‘Heat’, first introduced me to the absolute truth that:

Efficiency just means you can do more with less, which equals growth!”

Or, at best, we will maintain current levels of consumption which we know is already too much (three planets to much).

Coupled with the fact that we all need to pay the mortgage, feed ourselves and our families and put clothes on our backs; how do we continue to prosper on an economic basis, reduce our environmental impact and have a positive social impact (through our buildings in this instance)?

Enter the concept of The Living Building Challenge. An American standard. A tough one at that. There are three levels of certification, listed here from easiest to toughest;

  1. The Net Zero Energy Certification
  2. Petal Certification
  3. Living Building CertificationLiving Building Challenge logo

My stats on this will be slightly wrong but there are roughly 250 projects that have achieved Net Zero or Petal certifications. But no one has achieved the Living Building Certification.

So, what’s so good about this standard? For me it’s the philosophy of buildings being restorative rather than just ‘less bad’. To get the top slot you have to generate 105% of the electrical energy consumed by the building, treat and produce 105% of the water consumed and you can only build on brownfield sites (unless you can demonstrate an educational need to be fulfilled).

There are more challenges, but these three examples highlight the point of the restorative philosophy. Simply put, you are putting more energy and water back in than you take out. Building on a brownfield site is a brave move for any organisation as there will be a number of issues that will not be attractive; hazardous waste to deal with (old gas sites for example), run down surrounding areas, potential issues of crime to name a few.

But what better way to have a positive impact on society than to build a building (and surrounding biodiverse area) that is a shining example of what can be achieved by individuals who want to make a difference?

There are advantages, lower rates and financial incentives from councils to build in these areas. Imagine starting a trend and turning an area around into a thriving, sought after, business park and making a profit as a result? This would seem to suggest that doing the right thing could be profitable…

Living Building Challenge Aspects - Petals

Sitting within the Estates Team at Leeds Beckett University we are continually pushing sustainability. All of our contractors are achieving recycling rates of 95% plus and energy efficiency is a key factor in all designs. We have made it clear that we want investment appraisals (not cost savings on the project budget) and every option is considered from a whole-life-costing point of view, we specify recycled content in materials (information on this is surprisingly scarce when you dig into the detail) and space options are filled down to ensure buildings are the right size for their purpose. We’ve achieved BREEAM (Building Research Establishment Environmental Assessment Methodology) and Passivhaus standards and everyone is pleased. Rightly so, but… I’m hoping we get the go ahead for a building that will get us the Living Building Challenge full certification for the Leeds Sustainability Institute.

If we get the go ahead I’m looking forward to challenging current standards and taking my team, the wider estates team, and the design team on an educational journey that will be continued by our post graduate and research teams as well as the people who use the facility.

The New Zealand Education Act specifically states that one of the purposes of a university is to ‘be the social conscience and critic of society’. A building built to such high standards is a good public statement of this purpose.

There are already some good examples around, with one of my favourites being the Packard Foundation HQ.

Restorative has to be the way to go. To the construction industry it must seem like the vegan equivalent for building standards but after the Living Buildings Challenge there is Biomimicary………and the truly organic building.

  1. It’s time for buildings to start giving back rather than just taking from their environment. This is possible but is a step change, even when compared with other environmental standards such as BREEAM and LEED; standards which are all challenging. It is inspiring the read the requirements for the Living Buildings standard and see how it challenges not just conventions, but some legislation which often prevents innovation. This is the direction we need to be heading in. I look forward to the first Living Building certified building. After that it’s merely a case of extending the approach to our transport, food production, industries…. Inspiring and daunting.

  2. “My stats on this will be slightly wrong…But no one has achieved the Living Building Certification.”

    If one checks the LBC homepage, it’s quite easy to find the published figures for which levels have been acheived by specific projects, including ALL those projects that have achieved full certification. I greatly appreciate the effort that has been put into making these projects and their case statements easily accessible, especially to help reduce confusion regarding how many – it seems like it is quite clear. It’s a great resource, and I’ve found myself referencing it often to be clear and factual when communicating with project partners. There is much excitement around those that have been certified, those that are nearly there, and the rest who are in design and construction. The momentum from the number of projects is quite exciting!


  3. Mark, as an update to the certification numbers: As Eric mentioned above there are 20 Certified Projects to date, but I have been informed more projects will be announced at the Living Futures Conference in April as achieving certification (full or petal).

    Note there is also the time lag when registered projects await a qualifying 12 month performance proving period post construction.

    ILFI have updated their website with a list (and case studies) of certified projects – see and
