Five pioneering projects, all Irish low-energy buildings featuring German innovation, were chosen by the German-Irish Chamber of Industry and Commerce to showcase the coming together of German technology and the Irish appetite for energy efficiency. The five projects were presented at the Chamber’s event, ‘Showcase – Made in Germany’, which was held on November 27 at the Aviva Stadium, Dublin. Opening the event, Reinhard Giese, of the German Federal Ministry of Economics and Energy, spoke of the mutually beneficial relationship between Ireland and Germany in the area of energy efficiency. “At this event, we see five projects – all of which have been completed in the last two years – that present Ireland as an attractive location for German companies seeking partnerships and opportunities in the area of energy efficiency. We at the Ministry are confident that German Irish relations and partnerships in this sector will continue to flourish to the benefit of both countries into the future,” he said. The projects featured a range of energy efficient technologies applied across domestic, industrial and commercial projects. They reflect an Irish energy policy and building regulations that are ambitious, progressive and sustainable and illustrate how the rapid change in Irish building regulations has led to an increase in energy efficiency and building quality.
