Three labels in Europe – what are the differences?

Submitted by Baerbel Epp on June 22, 2018
collector labels Solergy (left) and Solar Keymark (centre top) as well as the EU Energy Efficiency label (right)Labels and trademarks should give the end-consumer a clear feedback on the quality and performance of the labelled product. Currently there are three labels available for solar products or solar assisted heating systems in Europe, so there is an increasing need to explain the differences to market players as well as customers. The chart above shows the two voluntary collector labels Solergy (left) and Solar Keymark (centre top) as well as the EU Energy Efficiency label (right) which is obligatory for water, space and combi heaters under the Energy Labelling (ELD) and the Ecodesign (EDD) Directives  since September 2015. 

IEA SHC: How to Turn Historic Structures into Nearly Zero Energy Buildings

Submitted by Baerbel Epp on May 17, 2017
Villa CastelliMore than one-fourth of all residential buildings in Europe date from before 1945. Over the past decade, preservationists have taken to the idea of renovating historic structures in an energy-efficient manner. The planned IEA SHC task titled Deep Renovation of Historic Buildings Towards Lowest Possible Energy Demand and CO2 Emission intends to find the best solutions to this challenge. The photo shows the Villa Castelli at Lake Como in Italy. The energy requirements of the building have been reduced and the remaining demand has been met by a heat pump and PV-generated electricity.

New Zealand: Over 35 Years of Steel Absorber Collector Production

Submitted by Baerbel Epp on December 19, 2016
Arthur WilliamsonFor more than 35 years, Thermocell collectors have been exclusively manufactured in New Zealand. Developed and commercialised in the late 1970s by Professor Emeritus Arthur Williamson from the University of Canterbury, these patented collector types have been produced in Christchurch ever since. In the peak years of 2005 and 2006, about 12 staff worked for Thermocell in administration, production and installation. As New Zealand’s solar thermal market has declined significantly over the past ten years, only two of those people are left today. “Arthur developed a reliable technology and we are maintaining systems which are more than 30 years old,” confirmed Ian Johns, General Manager of Sunstream Solar, a Thermocell collector reseller and installer from Christchurch. The photo shows Williamson in front of a “heat sheet”, the unique feature of Thermocell systems.

New Zealand: Prized School Air Heating Project

Submitted by Baerbel Epp on November 26, 2016
Solarventi New ZealandA New Zealand research project which deployed solar air collectors in schools to improve pupils’ health while reducing heat costs has garnered an award by the New Zealand Institute of Building this year. Robyn Phipps, Professor in Construction at Massey University’s School of Engineering and Advanced Technology, won the award for her research project conducted in cooperation with the Australian subsidiary of Danish air collector manufacturer Solarventi. The project led to the installation of solar air heating systems in ten classrooms of five primary schools in wintertime in 2013 and to the implementation of another batch of systems in 12 classrooms of six primary schools the following winter. Monitoring data showed that attaining similar temperatures in the control classrooms required 2.5 times the thermal energy used in the solar-heated ones.

New Zealand: SolarCity receives carboNZero Certificate

Submitted by Baerbel Epp on August 25, 2011

 SolarCity Collectors” SolarCity New Zealand Limited has been building, retailing and installing solar hot water systems for 30 years. To receive the carboNZero certification, the company has measured its greenhouse gas emissions pursuant to ISO 14064-1:2006 and has pledged to reduce them further. The carboNZero programme was established in 2001 by Landcare Research New Zealand Limited, a research institute owned by the New Zealand government. Since a merger with collector manufacturer and system supplier Solar Technology Systems Ltd in 2010, SolarCity has become New Zealand’s largest solar company and has, meanwhile, begun to offer off-grid and grid-connected PV systems as well.
