Construction and Demolition Waste (CDW) creates the largest waste stream in the European Union. They consist of a heterogeneous mix of different components and constitute large amounts of waste which are often hazardous. Although some CDW is sent for recycling after the stripping and the demolishing of the building, a bigger share of the recovered CDW is restricted to low-value applications. It is widely accepted that reliable strategies and innovative technologies need to be developed to increase the share of CDW‑derived materials in new residential constructions while simultaneously minimizing future CDW. Moreover, awareness and understanding the high value of CDW derived materials should be reached to improve building energy efficiency. The aim of the research is to evaluate the level of awareness and attitude towards CDW among Latvian construction companies. It was found out that Latvian construction business community has a positive attitude to waste management activities, and understands its importance in sustainable development

Resumen Este artículo presenta los resultados del proyecto de investigación "De residuos a recursos (W2R)" que analiza la generación de residuos de construcción y demolición (RCD) en obras de rehabilitación para la mejora de la eficiencia energética de edificios y desarrolla nuevos materiales, elementos y sistemas constructivos fabricados a partir de RCD. En este artículo se presentan algunos de los resultados del proyecto W2R, en concreto, la identificación, cuantificación y caracterización de las categorías de residuos generados en obras de rehabilitación para la mejora de la eficiencia energética llevadas a cabo en la envolvente vertical de los edificios. Para ello, se identificaron las actuaciones más comunes para mejorar la eficiencia energética de las envolventes verticales y se cuantificó la generación de RCD en dos obras utilizando métodos experimentales (datos in situ) y teóricos (software). Los resultados mostraron que la mayor cantidad de generación de RCD se produce durante las operaciones de preparación de la superficie vertical previas a desarrollar la actuación. Además, se encontró que las categorías de residuos más generados son: hormigón, cerámica, metal y madera. Abstract This article presents the results of the research project "From waste to resources (W2R)" that analyzes the generation of construction and demolition waste (RCD) in rehabilitation works for the improvement of the energy efficiency of buildings and develops new materials, elements and construction systems manufactured from RCD. This article presents some of the results of the W2R project, specifically, the identification, quantification and characterization of the categories of waste generated in rehabilitation works for the improvement of energy efficiency carried out in the vertical envelope of buildings. For this, the most common actions to improve the energy efficiency of the vertical envelopes were identified and the generation of CDR in two works was quantified using experimental methods (in situ data) and theoretical (software). The results showed that the greatest amount of RCD generation occurs during the vertical surface preparation operations prior to developing the performance. In addition, it was found that the most generated waste categories are: concrete, ceramics, metal and wood.

We investigate the factors (“drivers”) that motivated investment in energy efficiency in commercial real estate office buildings over the 2006–2011 and 2012–2017 period, and looking forward from 2018 in the context of growing concern over carbon emissions around the world. These insights were collected from large Canadian asset managers through interviews conducted in 2017 and 2018. Key findings were that (1) organizations noted an increasing number of factors driving investment decisions over the three periods; (2) cost drivers (payback period and anticipated financial returns) were the top two drivers in 2006–2017; (3) public relations factors became significantly more important looking forward, with brand (reputational impact) as the top-ranked driver and tenant attraction tied for third place; and (4) mitigation against risks such as resilience and anticipated compliance consistently increased in importance. This study contributes to a comprehensive understanding of past, present, and near-future sustainable real estate investment priorities, changing owner behaviors, and the perceived business case for building energy efficiency investments.
