IEA Solar Heating and Cooling Program

The International Energy Agency Solar Heating and Cooling Program (IEA SHC) is one of over 40 multilateral technology collaboration programs (also known as TCPs) of the International Energy Agency . [1] It was one of the first of such programs, founded in 1977. Its current mission is to ” advance international collaborative efforts for solar energy to reach the goal set in the vision of contributing 50% of the low temperature heating and cooling demand by 2030. ” [2] Its international solar collector Solar Heat Worldwide [3] serves as a reference document for governments, [4] financial institutions, [5]consulting firms [6] and non-profit organizations. [7]

Membership and organization

The IEA SHC’s members are national governments, the European Commission and international organizations. Each of the members is represented by the Executive Committee. [8] The IEA SHC Executive Committee meets twice a year and is headed by an elected chairman. The IEA SHC currently has 26 members (Australia, Austria, Belgium, Canada, China, Denmark, France, Germany, Italy, Mexico, Netherlands, Norway, Portugal, South Africa, Spain, Sweden, Switzerland, Turkey, United Kingdom, European Commission, ECREEE, European Copper Institute, Gulf Organization for Research and Development, ISES, RCREEE). [9]

Fields of work

Research, development and demonstration

The IEA SHC aims at facilitating international collaboration in the research, development and demonstration of solar thermal energy and solar buildings. Their multi-year projects (also known as “Tasks”) are conducted by researchers from different countries. Funding is provided by IEA SHC members, who usually pays for one or more national research institutions to participate in the work.

Research topics include:

  • solar space heating , eg Solar and Heat Pump Systems (Task 44), [10] Solar Combisystems (Task 26) [11]
  • solar industrial process heat , eg Solar Process Heat for Production and Advanced Applications (Task 49), [12] Solar Heat for Industrial Process (Task 33) [13]
  • Solar District Heating, Large Systems: Large Solar Heating / Cooling Systems, Seasonal Storage, Heat Pumps (Task 45) [14]
  • solar cooling , eg New Generation Solar Cooling and Heating Systems (PV or Solar Thermally Driven Systems (Task 53), Quality Assurance and Support Measures for Solar Cooling (Task 48), [15] Solar Air-Conditioning and Refrigeration (Task 38) [ 16]
  • solar energy / urban planning, Solar Energy and Urban Planning (Task 51), Solar Energy and Urban Planning (Task 51) (Task 47), [17] Solar Energy and Architecture (Task 41) [18]

As well as work on:

  • solar thermal energy storage (Task 42), Task 40, Solar thermal energy storage (Task 42), [19] Polymeric Materials for solar thermal applications (Task 39) [20]
  • standards & certification, eg Solar Standards and Certification (Task 57), Solar Rating & Certification Procedure (Task 43) [21]
  • resource assessment, eg Solar Resource Assessment and Forecasting (Task 46), Solar Resource Knowledge Management (Task 36) [22]

Task 13

The idea behind Task 13 is to push construction technology towards its limits to achieve the lowest possible total purchase energy consumption. Task 13 was part of the IEA Solar Heating and Cooling Program , to test the designs and techniques, and to monitor their performance.

On average, the houses were designed to be 44 kWh / m², 75% lower than the average 172 kWh / m² that would have been required. (Analysis of 11 of the houses in use Indicated That total savings made in practice Was Actually 60% [1] ) .The 44 kWh / m² resulted from:

  • Electricity – 18 kWh / m²
  • Space heating – 14 kWh / m²
  • Water heating – 11 kWh / m²
  • Cooling – 1 kWh / m²

In kWh / m², a combination of passive solar gains, active solar , and photovoltaics .

The buildings are constructed to be airtight , be superinsulated to roughly double normal standards, and to minimize thermal bridges . Masonry and several timber framed methods Were Represented, along with a novel steelStrengthened polystyrene block walls Were used. The Berlin “Zero Heating Energy House” included at 20m³ (700 cubic feet) seasonal thermal store . [2]

The homes in the program were:

  • Pleiade Row House, Louvain-la-Neuve, Belgium
  • Brampton Advanced House, Canada
  • Waterloo Region Green Home, Canada [3]
  • Kolding Row House, Denmark
  • IEA 5 House, Pietarsaari, Finland
  • Ultrahouse, Rottweil, Germany [4]
  • Zero Heating Energy House, Berlin, Germany [5]
  • Wish House 3, Iwaki, Japan [6]
  • Urban Villa, Amstelveen, Netherlands [7]
  • IEA Task 13 House, Hamar, Norway [8]
  • Roskar Low Energy House, Sweden
  • Duplex in Gelterkinden, Switzerland
  • Exemplary House, Grand Canyon, United States
  • Exemplary House, Yosemite, USA

Among the lessons learned were that:

  • Airtightness was difficult to achieve
  • Ventilation systems could suffer from noise and draft problems
  • Care was needed to design summer overheating
  • Simple facilities and systems were easier for the residents to understand

International SHC conference

In 2011, the IEA SHC Executive Committee announced an annual international conference on solar heating and cooling for buildings and industry. The first conference, SHC 2012 eu lieu 9-11 July 2012 in San Francisco ,. [23] SHC 2013 on 23-25 ​​September 2013 in Freiburg , Germany., SHC 2014 on 13-15 October in Beijing, China, SHC 2015 on 2-4 December in Istanbul, Turkey. SHC 2013 and SHC 2015 were jointly with the European Solar Thermal Industry Federation (ESTIF), which had previously organized their own conference, ESTEC.


The Solar Heating and Cooling Program publishes several cross-cutting documents, the most important one being the annual collector Solar Heat Worldwide . [3] The SHC Solar Update newsletter is published twice a year. [24]
