Methodology to assess the environmental sustainability of timber structures

Timber is a renewable material with excellent strength-to-weight ratios, insulating properties and it plays an important environmental role, acting as a CO2 sink. Public awareness of sustainability and its importance in the construction sector is growing day by day, encouraging the use of more sustainable materials, as is the case of timber. To assist in this goal, this study presents a methodology to prepare an Environmental Sustainability Index for Timber Structures (ESI-TS). In no way intended for comparison with other construction materials, the index arrives at an environmental sustainability classification, with its set of indicators and relevant weights.
