Wooden football stadium highlights rising demand for eco-friendly material

Forest Green Rovers in western England plans to build the world’s first modern football stadium, almost entirely using wood, one of the oldest materials in construction.

The club is proud to support the player’s commitment to veganism with the 5,000-seat arena designed by Zaha Hadid Architects as “the most environmentally friendly stadium in the world.”

A football club that plays in EFL League Two and aims to live up to the name of Forest Green, hopes to complete the construction of the Gloucestershire stadium by 2025 as an example of a material resurgence.

Demand for wooden buildings is rising against the backdrop of a desire for environmentally friendly and sustainable products backed by telecommuting and low interest rates, as well as a surge in home renovations and purchases.

Timber companies such as Stora Enso in Finland and KLHMassivholz and Binderholz in Austria will benefit, and the Nordic group forecasts rapid growth in the laminated lumber and other markets.

U.S. timber prices are still trading at $ 782 per 1,000 board feet, a pre-pandemic record, despite more than half the fall in the last two months as Americans began taking vacations again instead of refurbishing. Is significantly higher than.

The price of Finnish lumber, a guide to the European market, rose 57% annually to € 270 per cubic meter due to the full operation of the sawmill.

Traditionally, wood has been used to build small homes in North America, Scandinavia and Japan. But now, governments and businesses around the world are pushing to expand their use in larger public buildings, homes and offices.

Construction produces 10% of the world’s carbon dioxide emissions. This can help reduce CO2 by replacing concrete and steel while storing CO2 in building materials.

Andrew Carpenter, CEO of the Structural Timber Association (STA) in the United Kingdom, expects a significant increase in timber use, driven by the goal of zero carbon nets.

Currently, a quarter of homes are built of wood across the UK, but STA has seen this rise to one-third in the next few years after the government’s Climate Change Commission recommends its use in 2019. I predict that.

France requires more than half of the materials used in all public buildings to be wood or other sustainable materials, but the Wales government has announced that all wood frames will be available in affordable housing programs from 2022. Have already decided to use.

Much of the excitement is concentrated on laminated wood, especially cross-laminated wood, which has many different layers and can be prefabricated in large sections of the building at the factory.

Another type of glulam, glulam, can be used for longer spans and heavier loads, providing an alternative to steel beams that are nearly 80% lighter.

The new Google headquarters in London will be built incorporating cross-laminated timber. Meanwhile, Google’s parent company Alphabet is investing in the timber district of Toronto.

David Hopkins, CEO of the Federation of International Trade Associations for Timber, said timber is Off-site manufacturing Light and durable, it can be assembled quickly in the field. This should help the construction industry with labor shortages and low productivity.

“It’s time for a timber boom,” said Hopkins, whose Trade Federation represents 1,500 British companies. “There are natural living challenges. The construction process has become more productive and we are back in fashion from an aesthetic point of view.”

Some homebuilders, such as Barratt, Countryside and Persimmon, have acquired wooden frame makers to help them manage their supply chains.

In addition, with the help of changes in US building codes and architects choosing renewable products, wood coverage was increasing in the range of low-rise buildings, allowing designers to identify suitable materials. Helpful NBS Richard Waterhouse says.

This material is also used in skyscrapers. The tallest wooden building in the world is Norway’s 85-meter Mjostarnet Tower, while Vancouver is planning a 120-meter skyscraper made of wood.

However, the timber market faces some setbacks and failures.

Spiral costs and funding from the collapsed lender Green Sill meant that Softbank-backed “mass timber” startup Katerra was forced. Bankruptcy file In June.

The Grenfell Tower wasn’t made of wood, but the 2017 flames in a block of apartments in London are perceived as flammable, so they’re nervous about encouraging policy makers to use wood. became.

Industry figures claim that despite tragedy such as the Bradford City Soccer Stadium fire, which killed 56 people in 1985, the risk of fire in wooden buildings is overkill.

They say it’s a matter of how it is installed and handled, as well as all materials. “If you do all this correctly, [wood] It’s a very safe and stable material, “says NBS Waterhouse.

Forest Green Stadium is treated with a coating that delays the spread of fire and has a clear exit designed for quick escape.

However, Fred Mills, a former contractor expert and founder of The B1M, Youtube’s most subscribed construction channel, said the material was the driving force for use in UK public buildings. He said he faced a difficult battle to get.

“One of the biggest problems is that the basic cultural taste for concrete and steel is rooted,” he said.

“We have a culture of making things as cheaply as possible … at COP26 [the UN Climate Change Conference in Glasgow later this year]We cannot say that we want to lead the climate goals and continue construction with concrete and steel. “

However, despite the obstacles, some groups are pursuing expansion plans in anticipation of increased capacity.

Rob Harris, CEO of Accsys Technologies, which uses industrial vinegar to give softwoods its hardwood properties, sold enough wood to fill 24 Olympic-sized swimming pools from January to March, after selling enough wood. By 2025, we plan to increase production capacity by a factor of five from 2019 levels.

“The shift is astounding, but not necessarily policy-driven,” he added, adding that the office market was moving faster than the housing sector in switching to materials with strong green credentials.
