The Irish Republic has been one of the countries most hard-hit by the financial crisis; "SERVE has been a success during the deepest crisis Ireland has ever experienced," said Seamus Hoyne from the Limerick Institute of Technology in summarising his project experiences, and the results do indeed speak for themselves – 400 buildings renovated and 50 energy-efficient buildings built from scratch.
This project took a departure from the normal course by involving residents, 90 percent of whom actually owned the renovated buildings; the savings to be generated from the investment clinched the argument during the crisis.
There was a change of plan in Vitoria-Gasteiz, Spain, with 100 new houses originally to be built as part of a new-build project; then the crisis hit, causing a change in focus to renovating existing buildings from the Fifties and Sixties according to Iver Jan Leren from the PIME'S CONCERTO project.
Reto M. Hummelshøj from the ECO-City CONCERTO project demonstrated how fast renovation projects can break even for housing associations and local authorities – all of eleven years on average in a follow-up on projects completed in Helsingborg, Sweden, and Helsingør in Denmark. Renovation and new-build projects alike saw CO2 emission reductions amounting to 28 percent; the project has long since been completed, and increased efficiency would make these reduction rates difficult to match in the present, according to Hummelshøj.
One thing that Emil ter Horst learned from the cRRrescendo CONCERTO project was that preparation is so much more important in renovation than in new-build projects – "There are a lot more stakeholders you have to include in a renovation project than when you're constructing new buildings," an observation echoed by Sylvain Koch-Mathian from the RENAISSANCE CONCERTO project. Lessons learned by project partners in Lyon have even found their way into the new French Energy Regulation for the construction industry, according to Koch-Mathian.The CONCERTO projects also showed that rethinking technologies along with procedures could bring dividends, with a CHP plant in Milton Keynes, UK, serving as one such example; "This technology hasn't yet gained much traction in Britain, but our project has shown that CHP does work well, boosting its credibility," said ter Horst. Combinations of technologies, integration and monitoring are disciplines that offer an excellent opportunity for project partners to learn from one another, according to Károly Matolcsy from the Hungarian Research Institute EMI and PIME'S project manager.
The general consensus from the conference was that the evidence from many countries had shown the need for flexibility in renovation and new-build projects in what can be difficult conditions.Contact:

Innovative Photovoltaics – from the Lab to the Façade

Planet Earth experienced a global climate shift in the late 1980s on an unprecedented scale, fuelled by anthropogenic warming and a volcanic eruption, according to new research published this week.
Scientists say that a major step change, or ‘regime shift’, in the Earth’s biophysical systems, from the upper atmosphere to the depths of the ocean and from...
The Fraunhofer Institute for Solar Energy Systems ISE has installed 70 photovoltaic modules on the outer façade of one of its lab buildings. The modules were...
Nerve cells cover their high energy demand with glucose and lactate. Scientists of the University of Zurich now provide new support for this. They show for the first time in the intact mouse brain evidence for an exchange of lactate between different brain cells. With this study they were able to confirm a 20-year old hypothesis.
In comparison to other organs, the human brain has the highest energy requirements. The supply of energy for nerve cells and the particular role of lactic acid...
In laser material processing, the simulation of processes has made great strides over the past few years. Today, the software can predict relatively well what will happen on the workpiece. Unfortunately, it is also highly complex and requires a lot of computing time. Thanks to clever simplification, experts from Fraunhofer ILT are now able to offer the first-ever simulation software that calculates processes in real time and also runs on tablet computers and smartphones. The fast software enables users to do without expensive experiments and to find optimum process parameters even more effectively.
Before now, the reliable simulation of laser processes was a job for experts. Armed with sophisticated software packages and after many hours on computer...
