[Event] World Sustainable Energy Days

26-02-2013 | Europe欧洲

The GBPN Europe Hub, the Buildings Performance Institute Europe (BPIE) is attending the World Sustainable Energy Days this week in Wels, Austria. 

BPIE is conference partner to the European Nearly Zero-Energy Building Conference on Thursday and has a presentation on “Emerging trends in NZEB definitions”, a topic the institute has specialised in since its first report on ‘Principles for nearly Zero-Energy Buildings’ launched in November 2011. BPIE will also participate to the poster presentation and present its studies on nZEB and renovation roadmaps.

BPIE would be very happy to welcome you at its stand where you get can a multitude of information and material, also a presentation of the new GBPN website. 



The principles that guide decision making within the European Union.

A building that has a very high energy performance as determined in accordance with Annex I. The nearly zero or very low amount of energy required should be covered to a very significant extent by energy from renewable sources, including energy from renewable sources produced on-site or nearby.

A passive house is a building in which a comfortable indoor climate can be obtained without a traditional heating or cooling system. Compared to traditional building they use far less energy. For most countries these demands are 70–90 % reduced compared to the actual energy efficiency requirements for heating and cooling, but this depends on the actual energy standards. For countries with high energy efficiency requirements it is less. [Source: IEA (Laustsen J.) (2008) Energy Efficiency Requirements in Building Codes, Energy Efficiency Policies for New Buildings.]

A positive energy building is a building that on average over the year produces more energy from renewable energy sources than it imports from external sources. This is achieved using combination of small power generators and low-energy building techniques such as passive solar building design, insulation and careful site selection and placement.
