Australia: Economics of Solar Thermal, PV-based and Conventional Cooling System (2010)

Submitted by Baerbel Epp on April 20, 2011

 Lifetime Costs” In Australia, solar cooling is still a niche technology - despite good solar resources and a large air-conditioning and refrigeration market. The multiple market barriers which prevent the technology from achieving greater market shares are mostly economic in nature. During a presentation at the 9th IIR Gustav Lorentzen Conference 2010 in Sydney, Dr Paul Kohlenbach, Director of international solar cooling consultancy Solem Consulting, and Dr Mike Dennis of the Australian National University, highlighted these market barriers and opportunities for solar cooling in Australia. Kohlenbach himself has additionally carried out a study comparing the economics of a solar thermal, a PV-based and a conventional cooling system over a 20-year lifespan.

Solar Cooling: German Fraunhofer ISE compares PV and Solar Thermal

Submitted by Baerbel Epp on February 14, 2011

 Saved primary energy and difference in total annual cost ” Over the last 5 years, the number of installed solar cooling systems worldwide increased tenfold. The main obstacles for a more pervasive and faster market development are high upfront costs and lack of experience among main stakeholders, such as planners and architects. Based on various simulations, German institute Fraunhofer ISE analysed the saved primary energy and total annual costs of solar thermal, photovoltaic and conventional solutions for heating and cooling by using the example of a hotel in Madrid (see attached presentation).

Solar Heating and Cooling of Buildings (2007)

Submitted by Raquel Ponte Costa on February 3, 2011

This document includes detailed information about solar heating and cooling technologies for buildings. The document is one of the deliverables of the BRITA in PuBs project (Bringing Retrofit Innovation to Application in Public Buildings). This FP6 funded project involves different countries (Norway, Denmark, Italy, Greece, Germany, UK, Lithuania and Czech Republic). The aim is to develop demonstration projects in selected public buildings to demonstrate how renewable energies could be used.

Brazil: Solar Cooling System from Germany for Eco-Hotel Pousada do Parque

Submitted by Baerbel Epp on January 28, 2011

Solar Cooling System at Pousada do Parque” Since the beginning of 2011, solar cooling technology from Thuringia/Germany ensures a pleasant indoor climate in the rooms of the eco-hotel Pousada do Parque in Cuiabá, Brazil. On 15 January, the pilot plant came into operation, and since then, it has not only provided cold water, but also important input for a current campaign to accelerate the use of solar cooling technology in the Brazilian hotel sector.

Solar Energy Cools Milk (2009)

Submitted by Raquel Ponte Costa on January 6, 2011

This paper summarises the results of a study made in the framework of the European Commission co-founded project MEDISCO (Mediterranean Food and Agro Industry Applications of Solar Cooling Technologies).

The MEDISCO project (2006-2009) involves countries such as Italy, Spain, Germany, France, Egypt, Morocco and Tunisia. The objective is to assess (at a technical and economical level) the most appropriate solar thermally driven systems to tackle the current and future demand of the food and conservation industry sectors in the Mediterranean region.

Europe: 2011 Conferences dedicated to Solar Heating and Cooling

Submitted by Baerbel Epp on December 27, 2010

In Europe, only a few conferences focus exclusively on solar heating and cooling in 2011. Most events combine both solar thermal technology and photovoltaics, with two-thirds of the schedule being reserved for solar electricity and only one third for solar thermal. Please check the event calendar for more information about these events. The few events in 2011 that deal only with solar heating and cooling (and have been included in the event calendar, too) are listed in the following:
