“…The use of CLT in mass timber building costs $409 per m 2 floor area (0.21 m 3 of CLT per m 2 floor area), accounting 18% of total building construction cost. It is worth noting that the price range of CLT is relatively wide due to its early adoption status and nature as specialized product in building sector [17]. This current work modeled the LCCA using the glulam prices in RSMeans database [39] as a proxy for CLT, (e.g., $1440 per m 3 of CLT, construction labor/equipment cost of $219 per m 3 , and overhead of $260 per m 3 ), which is on the high end for CLT price.…”

“…In particular, there has been great interest in mass timber buildings in the Pacific Northwest, due in large part to the cost savings and regional economic benefits associated with local production of the mass timber products. Scouse and others [17] showed the local or regional economic benefits of mass timber over a comparable traditional concrete include direct and indirect jobs and economic growth, when CLT is locally sourced from regional manufacturers. Drivers for increasing MTC include both environmental life-cycle assessment (LCA) and life-cycle cost analysis (LCCA) benefits [18][19][20].…”

Global construction industry has a huge influence on world primary energy consumption, spending, and greenhouse gas (GHGs) emissions. To better understand these factors for mass timber construction, this work quantified the life cycle environmental and economic performances of a high-rise mass timber building in U.S. Pacific Northwest region through the use of life-cycle assessment (LCA) and life-cycle cost analysis (LCCA). Using the TRACI impact category method, the cradle-to-grave LCA results showed better environmental performances for the mass timber building relative to conventional concrete building, with 3153 kg CO2-eq per m2 floor area compared to 3203 CO2-eq per m2 floor area, respectively. Over 90% of GHGs emissions occur at the operational stage with a 60-year study period. The end-of-life recycling of mass timber could provide carbon offset of 364 kg CO2-eq per m2 floor that lowers the GHG emissions of the mass timber building to a total 12% lower GHGs emissions than concrete building. The LCCA results showed that mass timber building had total life cycle cost of $3976 per m2 floor area that was 9.6% higher than concrete building, driven mainly by upfront construction costs related to the mass timber material. Uncertainty analysis of mass timber product pricing provided a pathway for builders to make mass timber buildings cost competitive. The integration of LCA and LCCA on mass timber building study can contribute more information to the decision makers such as building developers and policymakers.

Wooden buildings with many advantages such as being lightness, durability, earthquake resistant, healthy, insulating, and esthetic are suitable for all kinds places especially earthquake zones. Cross-laminated timber (CLT) has increasingly become a viable alternative to other structural materials, mainly because of its excellent properties related to sustainability, energy efficiency, and speed of construction. This has resulted in the recent emergence of a significant number of CLT buildings constructed around the world. This is a study on determining the properties of CLT panels manufactured from wood species grown in Turkey and investigating of the structural behaviour and seismic resistant performance of them. Lumbers of 100 mm (width) x 50 mm (thickness) x 2400 mm (length) used in CLT manufacturing were obtained from eastern spruce (Picea orientalis L.) and scots pine (Pinus slyvestris) logs. Two replicate threelayered CLT panels of 2400 mm × 2400 mm × 150 mm in size were manufactured for each group. Density of the CLT panels was determined according to EN 323. The seismic resistant performance of the CLT shear walls was determined according to ASTM E 72 standard. CLT panels manufactured from scots pine gave higher seismic performance than those of CLT panels manufactured from spruce. The maximum load capacity of the walls increased with increasing the density values of the CLT panels.

“…It is thus necessary to unify both the functions and costs including the use of the surplus in order to examine the regional economic impact of the timber dam in comparison with the concrete dam. However, our previous study [19] and existing literature [20] did not consider these necessary aspects.…”

“…Regarding the use of wood for the construction of check dams, certain studies in the literature have evaluated life-cycle CO 2 emissions [15,16], estimated the potential for wood use and reduction in greenhouse gas emission [17], and calculated the structural stability [18]. However, with the exception of our previous study [19], no study has investigated the economic impact of timber dams, although a prior research has evaluated the economic impact of using timber as building material [20].…”

The regional economic impacts of the construction of timber and concrete check dams in Akita prefecture, Japan, were compared. When functions are appropriately unified, a concrete check dam is cheaper to build than a timber one; the difference in construction costs can be used by the government to issue premium vouchers as a regional promotion measure. To evaluate the effect of this, we extended the latest input–output table for Akita Prefecture to include timber and concrete check dam construction sectors. Concrete check dam construction with premium-voucher issuance had a total effect of 46,064,000 yen (economic impact ratio: 1.49; increased employment: 4.68 people). It also had an indirect economic impact on the plywood sector, since plywood was used as formwork, and issuing premium vouchers had a ripple effect on many industries in the region. However, timber check-dam construction had a total effect of 57,706,000 yen (economic impact ratio: 1.86; increased employment: 5.11 people) and a larger effect on the timber, logs, and silviculture sectors. Therefore, despite higher initial costs, timber check dam construction has the greater economic and employment impact on a region through its large ripple effects on the forestry and wood industries.
