FEATURES role timber can play in making buildings healthier and more sustainable from the inside.] TiQ: Another part of the mission is ‘to transform the building value and supply chain for a living future’. What does this mean for timber and its use in construction? MR: The Living Building Challenge is about bringing positive change to different industries, within the timber industry. I would imagine that it is critical that we ensure our forests are sustainably managed, and that deforestation is avoided. South Africa scores really well when it comes to sustainably managed forests. From our experience over the last 10 years in the green building industry, where we can improve is the Chain of Custody of FSC certified timber. Most Forests are FSC certified, but down the supply chain, this certification is lost, as timber gets mixed and there is not enough demand for pure FSC timber. TiQ: How does the use of timber for construction help promote projects that support sustainability and demonstrate strength in ecological restoration? MR: Timber is a great material that can assist a project with its biophilia goals, which is another important principle of the Living Building Challenge. Biophilia is the idea that people have an innate affiliation with nature, and integrating biophilia within your building design positively affects people living, working, and playing in the space. Biophilia can be integrated in many different ways, through the use of natural materials (for example timber) or shapes, colours, sounds, images of nature, real plants and so on. Another signature feature of the building is a glass-enclosed stairwell nicknamed the "irresistible stairway" that coaxes visitors into climbing it using panoramic views of downtown Seattle and Puget Sound. CONCLUSION Worldwide, there is a continuous drive to increase awareness of the benefits of using timber and to promote it as a building material. Any improvements in the way we construct can have a really positive effect on our environment and timber can play a large role in the solution. Using wood instead of conventional materials like concrete, steel and masonry not only reduces the amount of CO 2 emitted (at the rate of 0.9 tonnes of CO 2 per cubic metre of material used), but also locks away CO 2 for the lifespan of the product – if disposed of, this stored energy is then made available. While each type of material has its advantages – concrete and masonry have high thermal mass, for example, which is often required in a design – in general, the more wood we can use to replace other materials, the better for the environment. WHAT IS THE LIVING BUILDING CHALLENGE? and an inspiration to the surrounding community. The buildings are regenerative, contributing positively to the environment. The Living Building Challenge (LBC) is an initiative of the International Living Future Institute (ILFI), whose mission is ‘to lead the transformation toward a civilisation that is socially just, culturally rich, and ecologically restorative’; and which is ‘premised on the belief that providing a compelling vision for the future is a fundamental requirement for reconciling humanity’s relationship with the natural world’. As of June 2019, almost 600 projects around the world were registered to pursue certification under LBC and Zero Energy (ZE). The certification is verified after the building has been in operation for a minimum of twelve months and is able to demonstrate compliance based on actual performance. The core underlying principle of the Living Building Challenge is that buildings should mimic nature and natural systems. Living Buildings are buildings that meet the 20 stringent imperatives of the LBC standard, including being net zero energy, net zero water, using materials that are toxin free, and being beautiful www.timberiq.co.za The ILFI has an Ambassador Network that spans the globe, on every continent and in every time zone – with 709 Ambassadors in 43 countries, and 89 Collaboratives in 41 countries. Marloes Reinink has been an ambassador for the ILFI since 2015 and, as part of her role, has presented the ‘Introduction to the Living Building Challenge 3.1’ to over 600 people in South Africa. She was joined by Thulani Kuzwayo in 2017 and together they organised and facilitated a Living Future Collaborative for South Africa. In South Africa there are already projects that are actively seeking this certification – two residential projects in Oranjezicht, Cape Town; the 76 Corlett Drive office development in Johannesburg (targeting an LBC Petal certification); the Green School in Paarl which is currently under construction and targeting a full LBC certification; and Solid Green’s new office in Parkhurst, which is pursuing the Core certification. The Living Building Challenge is a philosophy, an advocacy tool and a certification tool for projects that aims to create regenerative buildings. // APRIL / MAY 2020 29
