Spain: Stakeholder Platform Solplat to Promote New Applications

Submitted by Baerbel Epp on November 14, 2017
SolplatOn 4 October 2017, the Spanish Ministry of Economy hosted the first general meeting of the newly created Technology Platform on Low Temperature Solar Thermal, Solplat. Funded by the ministry and promoted by Spain’s solar association ASIT, the umbrella platform was created to help companies, public authorities and universities support and improve segments which have seen fairly little market penetration to date. Examples are district heating, solar process heat and Nearly Zero Energy Buildings (NZEBs).
 

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.

Europe: Conferences That Offer Solar Heating and Cooling Sessions in First Months of 2015

Submitted by Baerbel Epp on February 28, 2015
WSEDEurope’s conference season now starts new after the end of 2014: This week, the World Sustainable Energy Days began in Wels, Austria, with a special focus on Nearly Zero Energy Buildings. Solarthermalworld.org is offering information about all important events on the Calender of Events and will highlight some upcoming conferences in this news piece. The variety of solar heating and cooling topics is great, but the technology remains on the sidelines during most conferences. The Calender of Events lists 70 renewable conferences and fairs until November 2016.

Switzerland: New Buildings to Reach Nearly Zero Energy Standard by 2020

Submitted by Baerbel Epp on January 24, 2015
Swissolar TrogenOn 9 January 2015, the Swiss Conference of Cantonal Energy Directors agreed on nationwide model rules for building energy codes. These rules include a nearly zero energy standard for new buildings from 2020 onwards and a 10 % renewable requirement for heating system retrofits. Although Switzerland is not a member of the European Union, the country’s energy standards are similar to what the European Energy Performance of Buildings Directive (2010/31/EU) requires from member states.

Nearly Zero-Energy Buildings: “Smart integration of home automation with heating technology”

Submitted by Baerbel Epp on June 13, 2014
Koebbemann-RengersAccording to the regulation on the overall energy efficiency of buildings, the European Energy Performance of Buildings Directive (2010/31/EU) passed on 19 May 2010, EU Member States must ensure that all new builds are nearly zero-energy houses from 2021 on – in the public sector, the directive will even apply two years earlier. With its energy-plus house designs, Bosch Thermotechnik has already been offering such solutions which not only meet but go below the future building standards. Already realised energy-plus houses mostly rely on combinations of PV system and electric heat pump. Many building designs also incorporate a solar thermal system for domestic hot water. Solarthermalworld.org spoke with Ralf Köbbemann-Rengers, Vice President Engineering Solar Thermal Systems and Storage Tanks at Bosch Thermotechnik.
