NOvel TImber CompositEs for Energy and seismic Upgrading of Buildings

Project description

A new concept for green, safe and cost-effective renovation of buildings in the EU

The building sector is crucial for achieving the ambitious energy and climate goals set out in the European Green Deal. Buildings are the single largest energy consumer in Europe. They are responsible for approximately 40 % of energy consumption and 36 % of greenhouse gas emissions. What is more, nearly half of the structures in seismic regions of the EU exhibit substandard seismic resistance. To boost building performance, the European Commission has announced the intention to launch a new 'renovation wave' initiative. The EU-funded NOTICE-EUB explores a cost-effective retrofit approach that combines advanced thermal insulation materials with engineered wood panels to provide simultaneous seismic-plus-energy upgrading. This new concept hinges on the high structural performance of the emerging cross-laminated timber technology and the superior thermal properties of advanced insulation materials.

Objective

This research project aims at developing novel timber composite systems for the combined seismic and energy retrofitting of existing building envelopes. Buildings in the European Union (EU) are responsible for 40% of the overall power consumption and 36% of energy-related carbon dioxide emissions. Meanwhile, nearly half of the structures in the seismic regions of the EU exhibit substandard seismic resistance, posing a severe threat to life safety and economy. The poor seismic performance of old buildings in the recent earthquakes in Italy and Greece caused significant economic losses, injuries, and loss of human lives. Currently, the annual cost of repair and maintenance of the European building stock is estimated to be approximately 50% of the total construction budget, exceeding €300 billion. Replacing the old buildings with new ones entails considerable financial, environmental, and social cost, which cannot be undertaken; therefore, extending the service life of buildings requires structural upgrade innovations that reduce their seismic vulnerability and boost their energy efficiency at the same time, and in the least expensive and invasive way possible. NOTICE-EUB explores a cost-effective retrofit approach, which combines advanced thermal insulation materials with engineered wood panels to provide simultaneous seismic-plus-energy upgrading. The proposed retrofit concept takes advantage of the high structural performance of the emerging cross-laminated timber (CLT) technology and the superior thermal properties of advanced insulation materials. The research activities comprise experiments on components and a full-scale building specimen to validate the efficiency of the advanced CLT systems, and to provide data for the calibration of numerical models. State-of-the-art analyses will evaluate the economic benefits of the proposed hybrid retrofit scheme. The final stage of the project envisages drafting of retrofit design guidelines and recommendations for the integrated interventions, as a contribution towards the development of new standards for the joint energy upgrading and seismic strengthening of the EU building stock.
