2020 Korea Wood Design Recognizes CWK’s Wood Infill Wall Demo Project with Top Excellence Award

The Suyu-dong wooden wall structure, a 5-storey concrete building in Seoul utilizes a wood-frame-infill system for its exterior and partition walls. A wood frame infill system is a unique hybrid that improves a building’s thermal performance while achieving a low carbon footprint. The results of a carbon assessment show that the wood products used in this building contain the equivalent of 44 metric tonnes of carbon dioxide, which equates to 29 fewer cars on the road for a year.

2019, Canada Wood Korea collaborated with SOSOL Architects, one of Korea’s wood champions, to demonstrate the effectiveness of wood infill systems and NLT (Nail-Laminated Timber) ceilings for industrialized construction by providing the materials and technical support for this showcase project.

 

 

 

 

Upon completion, project details were submitted for entry into the Korea Wood Design Awards and the building secured the Top Excellence Prize for 2020.

The building, located in Seoul, is used as ‘social housing.’ As Korea continues to see skyrocketing housing prices and limited land supply, affordable housing has been a key policy issue for Seoul’s mayors. One environmentally friendly solution to resolve this issue has been the construction of social housing. This increased demand for mid-rise buildings, which include apartments and condominiums for affordable housing, creates an opening for wood infill wall systems. Infill wall systems are an ideal solution because they can be built quickly, with higher energy performance and a lower carbon footprints. SOLSOLarchitects appreciate other benefits, such as the improved indoor air quality and versatility in renovation or remodelling.

SOSOL Architects’ Principal Architect Mr. Wang said, “This was the first wood infill wall project. At first, I was hesitant about combining the system with concrete, in terms of the cost and construction time in comparison to othermethods. Having recognized the positive outcome of this demonstration project, I will be happy to apply wood infill wall systems to our future projects.”

10 Year Field Testing Could Re-open Doors for Canadian Wood in Treated Product Sector

In November 2010, a Korean field-testing site for pressure-treated specimens of the Canadian refractory species White Spruce and Western Hemlock, was set up in Jinju-si, Gyeongsangnam-do. The samples were treated in Canada with the Residential Products Group C and D (specifications of the CSA Standard O80 Series with ACQ and CA), then brought to Jinju-si — a city on the southernmost part of the Korean peninsula where the average annual precipitation exceeds 1,500mm and termites are active.

2020 marked the 10th (and final) year for this field testing, and the annual inspection was conducted on December 16, 2020 by GNTECH professor Jong Bum Ra Korea Wood Preservation Association chairman Jae Yoon Ryu. Manager of New Construction Materials at FPInnovations, Rod Stirling, CWK’s Country Director Tai Jeong participated remotely by video during the inspection.

This test, which was designed to demonstrate the CSA O80 series’ preservative treatment, showed that the treated wood provided effective protection from both decay and termite attacks. The inspection revealed that the pressure-treated specimens of Canadian western hemlock and white spruce were in very good shape, both in areas with ground contact and in above-ground conditions, while the control group of untreated wood stakes (which were less than a year old) showed severe deterioration from both fungus decay and termite attack.

The 10 years of collected data will be compiled and analyzed to provide scientific data that supports the applicability of the CSA Standard O80 Series, and the creation of an  Association Standard for treated wood products. Canada Wood Korea expects the use of Canadian refractory species, such as Spruce and Hemlock, will be allowed again in the treated-wood sector’s new standard.

Global Pandemic Makes City Dwellers Reconsider Their Housing

With the arrival of COVID-19, many organizations made the move to operate from remote workplaces. As such, urban dwellers are reconsidering their locational lifestyle choices. There is no doubt that the pandemic will also push architecture and urban planning to evolve to accommodate consumer preferences.

Those who can afford working remotely might consider moving out of the city, trading long commutes for a larger single-family home lifestyle. This option has created a new demand for single-family homes, for which wood-frame construction is usually the preferred structure. Market share of single-family home wood construction rose from 2% in 2001 to over 15% by the end of 2020.

In addition to the elevated demand from the evolving housing market, the need for lumber is also on the rise due to increased demand from the ‘repair, remodelling and other’ end-use sectors — as people on “lockdown” spend more time at home. Canada Wood Korea is actively investigating these segments to target new opportunities for Canadian wood products.

Currently, some popular Korean TV reality shows have kicked enthusiasm for home renovation into high gear, and inspired home makeovers using wood frame components. Check out the video clips:

CWK Signed MOU with Jinju City for The Tech Support On Community Center To Be Built with Nail-Laminated Timber

On November 20, Canada Wood Korea (CWK) closed an MOU agreement with the Mayor of Jinju City. The agreement applied to the Community Center in Munsaneup, Jinju City using Nail-Laminated Timber products. Jinju City has been designated a ‘UNESCO Creative City with Crafts and Folk Art’  Jinju City and the City architect are trying to use wood as a building material in public buildings as much as possible. This Community Center will be the perfect example to optimize the city’s ‘Green Marketing’.

The NLT Community Center has been selected as a CWK’s Demo project in this fiscal year, and the construction is planned to start in mid-December of this year. Haustec Engineering is currently performing structural analysis on the NLT roof/wall structure and connection details.

CWK’s role in this project is to provide technical support throughout the planning and construction of the NLT structure in order to demonstrate the durability, energy-efficiency and cost-saving benefits of the wood-frame NLT roof and partitions.

Korea Abolishes the Height and Floor Area Limits on Wood Buildings

Recently, Korea made a landmark decision. The governmental Ministry of Land, Infrastructure and Transport (MOLIT) revised the Korea Design Standard (KDS), and as of November 9, 2020, abolished the total floor area and height limits for wood buildings.

 

Before the change, Korea Design Standards (KDS) limited the maximum height of wood buildings to 15 meters (at the eave) and 18 meters (at the roof ridge). Additionally, the gross floor area was limited up to 3,000 m2.

 

The demonstration project was Han-Green: a five-storey, mixed-use building, that incorporated two-hour fire-rated CLT (and other conventional and engineered wood products). The project was completed in 2019 by the Korea Forest Service.

 

“This change was possible because the Korean government recognized that the development of new high-performance wood products, such as CLT, were demonstrated to be safe both in structural performance and fire safety.”
