Promoting sustainable construction is one of the priority actions for achieving EU objectives around resource efficiency, climate change, economic recovery and sustainable development. However, equally important is the fact that 70% of Europeans lives in residential buildings that are more than 30 years old, which were generally built to lower environmental and health standards. These older buildings typically require ongoing renovation over time.

These renovations provide a challenge, but also an opportunity to improve the performance of the building in terms of energy efficiency and sustainability. Given that most households have limited economic resources, finding cost-effective ways to achieve this is vitally important. Upgrading of the housing stock requires all relevant actors, including administrations, designers and social workers, to understand the issues at stake and what they need to do.

In order to achieve the goal of convert the built heritage in sustainable housing, arises, as a crucial initial step, the need for a standard methodology for sustainable retrofit of social residential buildings to serve as an information tool of evaluation, classification and decision support to the administrations, designers, social workers, etc. when to undertake initiatives to
renovate residential buildings, incorporating the concept of sustainability in the existing housing stock, thus the barriers to sustainable retrofit.


Project goals:

- To develop a methodology to quantify, clarify and classify the sustainability of the actions in renovation of social housing.
- To demonstrate the feasibility of application, in renovation of social housing, technology, products and innovative building systems, tailored to the needs of each building and to the economic and social conditions of this type of housing, converting the existing housing stock in sustainable buildings, under the life-cycle approach of buildings and the integration of environmental considerations with economic and social conditions.

It specifically aims to:

- Increase the lifespan of buildings;
- Reduce the generation of construction and demolition waste by 170 tonnes per renovated social house;
- Increase the reuse of building materials and reduce demand for new raw materials by 180 tonnes per house, thereby reducing associated energy consumption by 18.48 Tpe (total power exchange) and CO2 emissions by 68.37 tonnes;
- Reduce the annual energy consumption in retrofitted houses by 0.33 Tpe (total power exchange) and associated CO2 emissions by 1.22 tonnes; in order to reduce the energy dependency of EU from other regions.
- Increase the comfort and value of social housing, and contribute to increasing their purchasing power by reducing energy bills for occupiers by some 30% - thus increasing their overall economic well-being by 1.6-4.8%.
- To reduce the existent inequalities between neighborhoods of social housings and the rest.
The NEWsolutions4OLDhousing project aims to establish a standard methodology for the sustainable retrofitting of social housing. This will serve as a tool to help stakeholders overcome some of the existing barriers to the achievement of sustainable housing in the EU.

The project will identify new technologies, products and innovative building systems for the retrofitting of social housing and demonstrate the feasibility of their application when tailored to the physical, economic and social conditions of each building or type of housing.
It will look at how existing building materials can be used in the construction of more sustainable housing.

Based on these experiences, the project will develop an on-line tool to quantify, clarify and classify the sustainability of actions for retrofitting housing. This will provide architects, builders, decision-makers and authorities with greater awareness and knowledge of the sustainable solutions for retrofitting old housing and reusing old materials.

The project ultimately hopes to promote the implementation of optimised building concepts that have the potential to decrease impacts associated with the lifecycle of buildings.
Expected results:

- A standard methodology for the sustainable renovation of social housing, including an on-line assessment, evaluation and decision-making tool for stakeholders;
- Decreased energy consumption and resource use in the construction sector (0.33 Tpe and 1.22 tonnes of CO2 emissions annually per retrofitted unit)
- To recommend realistic measures to diminish consumption of resources required for the manufacture of building materials for a new housing in 180 tons of raw materials, 18.48 Tpe of energy consumption, and 68.37 tons of CO2 emissions per renovated house
- Social and economic benefits for the social housing sector (increase economical capacity of households between 1.6% and 4.8% annually, as result of reduce the cost of energy bills about 30%)
