Summary
AcoustiTECH is a North American leader in acoustic solitions and has quickly become the reference standard in the industry. For 25 years, AcoustiTECH has teamed uo with Architects, builders, general contractors, acoustic consultants and other stakeholders to help them achieve their vision by providing proven acoustical solutions and expertise. AcoustiTECH looks at the specific requirements of each individual project, evaluates the requirements, determines the needs and provides personalized solutions. AcoustiTECH's approach is unique, efficient and reliable. We possess our own acoustic laboratory that we use for our research and development in order to recommend the best acoustic solutions by type of structure. Thousands of tests have been performed inclusing over 300 on heavy timber assemblies. The principal objective of creating this document is for the professionals to compare and choose from 25 assemblies the ones that suit their needs the best. The most interesting and popular assemblies have been selected and compared side by side in the same environment, built and tested by the same professional unisg the same flooring materials. It is important to note that the quality of construction can affect the performance. Indeed, construction standards and assemblies recommendations must be followed in order to reach the seeking performance.

Summary
This report represents the results of the activities performed in working group 1, Basis of Design. The most important task of working group 1 was the defragmentation and harmonization of techniques and methods that are necessary to prove the reliable, safe and economic application of timber materials or products in the construction industry. This report is structured into five parts. At first general principles regarding the design formats are addressed (Part I). Afterwords timber specific aspects regarding code calibration (Part II) and serviceability (Part III) are summarized. In Part IV other demanding issues for the implementation into Eurocode 5 are addressed. Here also summaries of joint activities with other working groups on cross laminated timber and timber connections are presented. The report concludes with a guideline for data analysis (Part V).

Summary
Americans spend about 90 percent of their time inside. As a result, building professionals are rethinking how people design, use and occupy buildings. Biophilic design is increasingly used to boost occupant well-being through connection to nature and the use of natural elements like daylight, plants, water and exposed wood. These elements have been attributed to positive outcomes in humans—from reducing stress to boosting productivity. Today, this emerging trend is increasingly a market expectation, with tenants seeking sustainable, functional and aesthetically pleasing features throughout their offices, homes, retail and hospitality spaces. Published jointly with our partners at Think Wood, this engaging and stunning LookBook considers the role of wood in the context of biophilic design principles.

Summary
Buildings and the construction sector together account for about 39% of the global energy-related CO2 emissions. Recent building designs are introducing promising new mass timber products that have the capacity to partially replace concrete and steel in traditional buildings. The inherently lower environmental impacts of engineered wood products for construction are seen as one of the key strategies to mitigate climate change through their increased use in the construction sector. This chapter synthesizes the estimated carbon benefits of using engineered wood products and mass timber in the construction sector based on insights obtained from recent Life Cycle Assessment studies in the topic area of reduced carbon emissions and carbon sequestration/storage.

Summary
The report describes a new structural system in wood that is the first significant challenger to concrete and steel structures since their inception in tall building design more than a century ago. The introduction of these ideas is fundamentally driven by the need to find safe, carbon-neutral and sustainable alternatives to the incumbent structural materials of the urban world. The market for these ideas is quite simply enormous. The proposed solutions have significant capacity to revolutionize the building industry to address the major challenges of climate change, urbanization, sustainable development and world housing needs.

Summary
Depending on the severity, fire damage can compromise the structural integrity of wood structures such as buildings or residences. Fire damage of wood structures can incorporate several models that address (1) the type, cause, and spread of the fire, (2) the thermal gradients and fire-resistance ratings, and (3) the residual load capacity. The investigator should employ engineering judgment to identify those in-service members that are to be replaced, repaired, or can remain in-service as they are. Suchjudgment will likely be based on the visual inspection of damaged members, connections, and any protective membranes.

Summary
The CLT Handbook provides vital “How to” information on CLT for the design and construction community, and is a great source of information for regulatory authorities, fire services and others. The CLT Handbook is also a good textbook for university level timber engineering courses. In summary, the Canadian CLT Handbook will remain the most comprehensive reference for sharing the latest technical information on North American CLT. The Canadian edition of the CLT Handbook, first published in 2011 under the Transformative Technologies Program of the Natural Resources Canada, played an imperative role in accelerating the use and acceptance of CLT in North America. Its introduction subsequently led to the publication of the US Edition. The Canadian Edition supported the early use of CLT products from Canadian manufacturers in many small to large projects across Canada and the US, and paved the way for CLT and other wood products to be used in new applications like tall and large buildings, and bridges. Since then, additional research has taken place globally and substantial regulatory changes have occurred enabling more wood to be used in construction. Those developments highlighted a need for the CLT Handbook to be updated. The 2019 Edition of the CLT Handbook, for example, augments the recently developed CLT provisions in CSA Standard in Engineering Design in Wood and it includes a design example of an 8-storey CLT building. It helps expand the knowledge base of the designers about CLT enabling them to develop alternative solutions for taller and larger buildings that are beyond the boundaries of the acceptable solutions in building codes.

Summary
Cross-Laminated Timber (CLT) is an engineered mass timber product manufactured by laminating dimension lumber in layers with alternating orientation using structural adhesives. It is intended for use under dry service conditions and is commonly used to build floors, roofs, and walls. Because prolonged wetting of wood may cause staining, mould, excessive dimensional change (sometimes enough to fail connectors), and even result in decay and loss of strength, construction moisture is an important consideration when building with CLT. This document aims to provide technical information to help architects, engineers, and builders assess the potential for wetting of CLT during building construction and identify appropriate actions to mitigate the risk.
