IEA Task 51: Challenges in Urban Planner Education

Submitted by Baerbel Epp on July 27, 2017
Task 51 MapCities and large municipalities all around the world have taken the lead in sustainability, and urban planners find themselves in the important position of having to devise solutions for integrating renewable and energy efficiency measures at local level. Each city has its own unique set of resources and pattern of energy use. But as solar energy is available everywhere to some extent, there will be an urgent need to develop the expertise and skills of solar industry stakeholders in urban planning. Researchers from the IEA’s Solar Heating and Cooling Programme’s Task 51, Solar Energy in Urban Planning, have examined the educational offerings of universities and colleges in nine partner countries (Australia, Austria, Canada, France, Germany, Italy, Norway, Sweden and Switzerland), identified gaps in knowledge and designed solutions to overcome them. 
 

China: Sunrain Finalises Strategic Cooperation Agreements

Submitted by Baerbel Epp on June 30, 2017
Natural Ressources CanadaThe Chinese Sunrain group, the world’s biggest collector manufacturer, is broadening its product portfolio to include large-scale solar thermal plants. Sunrain had already made the first step towards globalising its strategic partnerships by establishing a joint venture with Danish-based Arcon-Sunmark in June 2016. It has now concluded a cooperation agreement with CanmetEnergy in Canada with the aim to develop solar district heating systems using borehole heat storage fields for seasonal storage in China. Canada’s Minister of Natural Resources Jim Carr (back row 2nd from left) oversaw the signing of the agreement during his visit to China in June 2017. The agreement was signed by Xinjian Xu, Founder and Board Chair of Sunrain Solar Energy (front right) and Frank Des Rosiers, Assistant Deputy Minister of Natural Resources Canada’s Innovation and Energy Technology (front left).

SOLTRAIN Lesotho: Small Country, Big Accomplishments

Submitted by Baerbel Epp on March 17, 2017
In July 2013, the small country of Lesotho in southern Africa joined the SOLTRAIN project. Between then and the end of phase II of SOLTRAIN – the Southern African Solar Thermal Training and Demonstration Initiative – in February 2016, training courses were held, demonstration projects realised and awareness campaigns carried out. The Bethel Business and Community Development Centre (BBCDC), a commercial and technical school which is in a remote district of Lesotho and has 125 full-time students, has been the main partner organisation supporting these activities. Two solar water heaters at BBCDC, one thermosiphon and one pumped system, were installed during training courses (see photo). Obviously, this has raised awareness of the technology among all students learning and living at BBCDC, who use the solar-heated water every day. The efforts of the BBCDC won the school the Energy Globe Award Lesotho in 2014, 2015 and 2016.

Solar Canada 2017, Toronto

Submitted by Baerbel Epp on January 10, 2017
Solar Canada 2017 CanSIA's Annual Conference & Exposition will take place at Metro Toronto Convention Centre from 4 to 5 December 2017. The Conference and Expo is expected to attract solar industry professionals and serious solar energy consumers, including CanSIA members, Manufacturers, Dealers, Architects, Installers, Utilities, Financial and Government representatives, NGOs and Solar energy consumers. Exhibitors from all across Canada, the United States and other countries are expected to attend.
 

Canada: Solar District Heat Meets Community’s Entire Space Heating Demand

Submitted by Baerbel Epp on December 9, 2016
Drake Landing CanadaThe Canadian Drake Landing Solar Community has hit a new performance milestone, recording its first year of solar-only space heating during heating season 2015-2016. The community’s SDH plant, which has been in operation since 2007, was initially designed to achieve a solar fraction of 92 to 93 % for space heat in an average year. System improvements have increased that share and have made last winter the first time that solar energy was able to meet 100 % of the space heating requirements of the 52 energy-efficient residential buildings. The families heat their hot water with their own solar water heaters and gas-fired boilers. The initiator of the project was Natural Resources Canada (NRCan), which has since remained the central technical support.

IEA SHC: Attractive Solar Solutions for Urban and Landscape Planning

Submitted by Baerbel Epp on September 15, 2016
Case Studies Task 51How can urban planners be convinced to consider solar energy technologies in municipality projects? This is the key challenge faced by the international group of researchers of Task 51, Solar Energy in Urban Planning. One way to attract interest from these planners is to present them with case studies of successfully implemented solar projects. So the members of Task 51 headed by Maria Wall, Professor at the Energy and Building Design department of Sweden’s Lund University, have collected around 40 solar case studies and are about to design a brochure for all of them. The authors distinguish between three types of studies: new urban areas, existing urban areas and landscapes.

TASK 45 / 55: Guidelines on How to Design Seasonal Storage

Submitted by Baerbel Epp on August 1, 2016
Bore Hole StorageSeasonal storage is a key component in the transformation of today’s energy industry. Besides storing energy in summer for heating in winter, it can also be used to save waste heat from the industry and to increase the electricity production from biomass CHP plants. Experiences gathered with the technology during case studies were summarised as part of the study Seasonal thermal energy storage – Report on state of the art and necessary further R+D, which was published by Task 45, Large Scale Solar Heating and Cooling Systems, of the IEA SHC programme. Together with the Guidelines for Materials & Construction on the two most common storage types, borehole (see the chart) and water pit, it provides a good overview of the current advancements in this field (all three documents attached). Additional research into the design of seasonal storage will be carried out in follow-up Task 55, Towards the Integration of Large SHC Systems into District Heating and Cooling (DHC) Network. Interested stakeholders have been invited to join the kick-off meeting of Task 55 in Graz, Austria, between 19 and 21 October (see contact details below).

IEA SHC: Levelised Cost of Heat and the Calculations behind It

Submitted by Baerbel Epp on May 28, 2016
The main objective of IEA SHC Task 52, Solar Thermal in Energy Supply Systems in Urban Environments, is to call attention to both the technical and economic aspects of solar heating and cooling usage in densely populated urban areas. Urban planners and commercial clients want to know the costs compared to the energy output generated by various solar heating technologies. A method to benchmark different solar heat production systems is Levelised Cost of Energy (LCOE). This method is described by the IEA as the “average price that would have to be paid by consumers to repay exactly the investor/operator for the capital, operation and maintenance and fuel expenses, with a rate of return equal to the discount rate”. The chart shows the LCOE for different applications and system sizes in northern / central European climates, taken from the most current Task 52 study Technology and Demonstrators (for further details see table below). The author of the study, Franz Mauthner from Austrian research institute AEE INTEC, contributed to this article, which elaborates on the method and the calculations behind it.
