PEFC showcases carbon-negative housing complex

PEFC Austria handed over a 4-metre-high fir tree to the Austrian parliament.

Located in east London, Dalston Lane is a multiple award-winning private residential building. Nearly 34 metres high, it is one of the world’s largest load-bearing buildings made of cross laminated timber (CLT).

The landmark development, built by B&K Structures and Waugh Thistleton Architects, used CLT panels certified by the PEFC (Programme for the Endorsement of Forest Certification) for the external and core walls, right through to the floors and stairs.

Dalston Lane has a gross external area of more than 11,000 square metres, and incorporates 121 residential units, comprising contemporary style apartments, spread across nine floors.

As well as meeting the need for high quality, high-density housing, the use of timber technology has significantly reduced the carbon footprint of the building in terms of both material production and onsite energy consumption.

Dalston Lane has a negative carbon footprint, meaning that it removes more CO2 from the atmosphere than it adds. The project’s net carbon footprint of 2,600 tonnes CO2 represents a saving of an estimated 4,600 tonnes of CO2 compared to equivalent concrete buildings.

To put this in perspective, the carbon removed from the atmosphere in the construction of Dalston Lane is equivalent to the emissions produced by 1,703 cars over a year.

The block weighs only a fifth of a concrete building of the same size, and using CLT reduced the number of deliveries during construction by 80%. As a rapid, robust and reliable offsite manufactured solution, CLT delivers many benefits during the construction process and beyond.

Manufactured to exceptional levels of accuracy in factory controlled conditions ensures minimal defects and improves construction and project delivery time, reducing costs and maximising efficiency on all levels – providing cost and programme certainty.

Christmas trees

This past Christmas, several European cities chose PEFC-certified Christmas trees for a sustainable celebration. One of the certified Christmas trees was in London’s Covid-restricted style at of the iconic Trafalgar Square.

The traditional annual gift from Norway to the UK is the 74th in the series of trees donated by Oslo to London. Oslo has sent a tree to London every year since 1947 as token of gratitude, celebration and commemoration of Britain’s support during World War II, when the Norwegian government and royal family lived in exile in London from 1940 to 1945 during Norway’s occupation.

The 80-year-old, 23-metre-tall Norwegian spruce was sourced from a PEFC-certified forest in Maridalen, Oslo. Weighing about 200 kg, it was transported to London by road and sea.

Sustainable festive splendour also came to the Austrian parliament. PEFC Austria handed over the 4-metre-high fir tree to the National Council Presidents.

The tree brings a breath of ‘Silent Night’ to the parliament, as it comes from a PEFC-certified forest in Arnsdorf, Salzburg.
