Timber construction offers excellent opportunities for a sustainable building life. The end of life of a building is also important to consider: timber can more easily be reused, repurposed or recycled than other building materials. This supports the transition towards a circular economy – where materials undergo a life cycle assessment and are repurposed after their initial service life.

Improving thermal performance of existing timber frame buildings

This Wood Information Sheet outlines the options for improving the thermal performance of existing timber frame buildings and summarises the important issues that specifiers should consider when implementing improvements.

 

Recovering and minimising waste wood

Wood and wood-based products are used in a wide range of applications, some with service lives of many decades before they enter the waste stream. However, it is only since the mid-1990s that an industry has emerged to recycle waste wood, where qualities such as a low moisture content compared with virgin wood have made recycled wood fibre popular for a variety of applications.

 

Life cycle costing

Life cycle costing is a decision-making technique which takes into account both initial and future costs. For buildings and structures this usually means considering not just capital costs but relevant costs in use (operational costs) such as maintenance, component replacement, utilities, managing the asset for a given period, and end-of-life costs.

 

Life Cycle Assessment

Many industries, rather than simply responding to increasingly stringent regulation, are now actively seeking to develop more environmentally benign products and processes. Life Cycle Assessment (LCA) is one of the best known tools for assessing the environmental impact of activities.
