A State of the Art of the Overall Energy Efficiency of Wood Buildings-An Overview and Future Possibilities.
TLDR
In this article, the authors present a review of the state of the art of wood constructions with a particular focus on energy efficiency, which could serve as a valuable source of information for both industry and scholars.Abstract:
The main goal of this study was to review current studies on the state of the art of wood constructions with a particular focus on energy efficiency, which could serve as a valuable source of information for both industry and scholars. This review begins with an overview of the role of materials in wood buildings to improve energy performance, covering structural and insulation materials that have already been successfully used in the market for general applications over the years. Subsequently, studies of different wood building systems (i.e., wood-frame, post-and-beam, mass timber and hybrid constructions) and energy efficiency are discussed. This is followed by a brief introduction to strategies to increase the energy efficiency of constructions. Finally, remarks and future research opportunities for wood buildings are highlighted. Some general recommendations for developing more energy-efficient wood buildings are identified in the literature and discussed. There is a lack of emerging construction concepts for wood-frame and post-and-beam buildings and a lack of design codes and specifications for mass timber and hybrid buildings. From the perspective of the potential environmental benefits of these systems as a whole, and their effects on energy efficiency and embodied energy in constructions, there are barriers that need to be considered in the future.read more

Preparation of Breathable Cellulose Based Polymeric Membranes with Enhanced Water Resistance for the Building Industry.
Atif Hussain,Pierre Blanchet +1 more
TL;DR: Bio-based membranes with enhanced vapour permeability for use within building envelopes have immense potential as durable, eco-friendly, weather resistant barriers for the building industry as they can adapt to varying humidity conditions, thus allowing entrapped water vapor to pass through and escape the building, eventually prolonging the building life.

Demonstration of energy savings of cool roofs
TL;DR: In this paper, the authors show that reflective roofs can reduce the difference between the surface and ambient air temperatures by as much as 20 F, while for highly-reflective roofs with similar insulative properties, the difference is only about 20 F.

Concrete vs. wood in buildings – An energy system approach
TL;DR: In this paper, the authors compare buildings with concrete frames and wood frames concerning their life-time carbon dioxide emissions as well as their total material, energy and carbon dioxide costs, and conclude that it is unclear whether wood framed buildings will be a cost-effective carbon mitigation option and that further analyses of costs should be performed before prescriptive materials policies are enforced in the buildings sector.
