SHC 2017: Largest experts’ meeting on integrated solar heating and cooling

Submitted by Baerbel Epp on November 8, 2017
SHC2017_1500 experts from more than 50 countries attended the 5th International Conference on Solar Heating and Cooling (SHC) in Abu Dhabi, UAE, from 30 October to 2 November 2017. It was the first time that this biennial conference by the IEA’s Solar Heating and Cooling Programme had been organised jointly with the Solar World Congress by the International Solar Energy Society (ISES). The new partnership resulted in 2017’s largest experts’ meeting on integrated SHC solutions for buildings, industry, cities, regions and utilities, and in over 300 presentations.

Renewable Global Futures Report: Experts Divided on Future of Heating

Submitted by Baerbel Epp on July 5, 2017
CoverIs the transition to 100 % renewables at global level a feasible and realistic objective? What share will renewably sourced heat have by 2050? Will the electrification of heat continue? These are three of more than 100 questions which were answered in interviews with 114 experts from all around the world. Interviewees came from NGOs, research institutions, governmental bodies and international organisations. REN21’s Renewable Global Futures Report published in April 2017 summed up their explanations as part of twelve Great Debates. Lead author Dr Sven Teske from the University of Technology Sydney, Australia, presented some of the key findings of the report during a June webinar organised by the International Solar Energy Society. 
 

Germany: Solar + Heat Pump + Ice Storage Achieves Seasonal Performance Factor of 5.6

Submitted by Baerbel Epp on June 22, 2015
Ice storage ConsalarGerman company Consolar offers a heating system called SOLAERA, which combines a heat pump with a specially designed solar collector and a heat storage space using the latent heat released when water freezes to ice (see photo). The solar heat pump system with 18 m² of collector area, a 300 litre ice storage space and a 1,000 litre buffer tank provides enough energy to heat a well-insulated building in Germany. In a field test by a local environment group, Lokale Agenda 21, it achieved a Seasonal Performance Factor (SPF) of 5.6, putting performance even above prior simulations. The SPF describes the ratio of delivered heat to electricity consumed over the entire year. Consolar sold about 160 solar heat pump systems in total, mostly in Germany but also in Denmark, the UK, Switzerland, Belgium, France and Italy. The systems there achieved SPFs between 3.5 and 6, depending on collector field size, maximum flow temperature and heat demand.

Solar Thermal Energy (2007)

Submitted by Raquel Ponte Costa on June 20, 2015

This document was prepared in 2007 by the University of Gavle. The document gives a detailed introduction to solar thermal power, as well as descriptions of various energy applications and active and passive solar heating systems.

The report breaks down in detail the different types of solar thermal systems and collectors. Charts, graphs and photos show the various examples listed.

Development of a Solar Rating and Certification Laboratory in Minnesota (2009)

Submitted by Raquel Ponte Costa on June 16, 2015

This is a report prepared by the Minnesota Department of Commerce Office of Energy Security (OES) to the Legislature. It focuses on solar thermal technologies for domestic hot water and space heating. This legislation came about from concerns that the nationally recognized solar thermal certification organization, Solar Rating and Certification Corporation (SRCC), process was inadequately serving Minnesota’s solar thermal industry.

Building Integrated Solar Thermal Roofing Systems History, Current Status and Future Promise

Submitted by Raquel Ponte Costa on June 16, 2015

This document was prepared by the American Solar Roofing Company and explains building integrated solar thermal (BIST) designs. There are four characteristics mentioned in this report to help distinguish the different types of BIST roofing: roof panel size, heat transfer fluid containment, glazing and focusing methods. It discusses the history of BIST and mentions some of the earliest examples of this technology. It also explains the composition of these systems, describing the materials used and how it works.

Concentrated Solar Power – Focusing the sun’s energy for large-scale power generation (2009)

Submitted by Raquel Ponte Costa on June 15, 2015

This fact sheet was written by the Environmental and Energy Study Institute in 2009. The document starts with a brief background on solar thermal energy and then describes the different types of solar thermal systems (parabolic trough, linear fresnal reflectors, dish/engine, power tower). It covers nighttime generation and how systems use supplemental fuels or thermal storage. The “Water and Land Impacts” section discusses land requirements for single rooftop systems to large power tower systems and water usage.

Green Institute Issue Brief on Solar Energy (2008)

Submitted by Raquel Ponte Costa on June 13, 2015

This report was issued by the Green Institute in 2008 and discusses the option of a “solar carve-out” to build Minnesota’s solar future. To develop Minnesota’s renewable sources beyond 25 percent, development of additional renewable energy will be necessary, specifically solar technology. A carve-out is an addition to a renewable energy standard (RES) that specifies a portion of the RES needs to be met with a particular technology – solar.

Unified Facilities Criteria (UFC) – Solar Heating of Buildings and Domestic Hot Water (2004)

Submitted by Raquel Ponte Costa on June 13, 2015

This handbook was released by the US Department of Defense in 2004. It presents design criteria and cost analysis methods for sizing and justification of solar heat collectors for potable water and space heaters. Sufficient information is presented to enable engineers to design solar space conditioning and water heating systems or conduct feasibility studies based on solar collector performance, site location, and economics. Both retrofit and new installations are considered.
