American Solar Works – Harness Your Energy for Your Business (2008)

Submitted by Raquel Ponte Costa on June 13, 2015

This document was prepared by the American Solar Works Holdings LLC. While it gives background information, it primarily tries to encourage solar thermal use for commercial buildings and businesses. Several commercial examples are used of what solar thermal can be used for including: heating hotel domestic hot water, providing showers for athletes and students, washing livestock, providing “green” clean clothes at a laundry mat, heating a building in the winter and augment your absorption chilling in the summer.

Heating Water with Solar Energy Costs Less at the Phoenix Federal Correctional Institution (2004)

Submitted by Raquel Ponte Costa on June 13, 2015

This report was released by the Energy Efficiency and Renewable Energy section of the U.S. Department of Energy in 2004. It highlights a large-scale solar thermal system installed at the Phoenix Federal Correctional Institution (FCI) and breaks down the statistical output. The system was financed through an Energy Savings Performance Contract (ESPC), which include an average annual savings of $6,700.

UTILITY SUCCESS STORIES IN SOLAR WATER HEATING (2003)

Submitted by Raquel Ponte Costa on June 13, 2015

This paper was prepared by a collaboration between the Hawaiian Electric Company, Eugene Water & Electric Board, Lakeland Electric, Wisconsin Public Service and JEA in 2003. Four utility solar water heating success stories are mentioned from Hawaii, Oregon and Florida. This paper recognizes that the U.S. solar industry is stable and poised for growth, but is still not broadly accepted. Support organizations are mentioned, along with what qualifications go into solar thermal installation before they mention the success stories.

Solar Thermal Solutions in Boston and the Northeast (2008)

Submitted by Raquel Ponte Costa on June 13, 2015

This PowerPoint was developed by KeySpan in 2008. It covers why they promote solar thermal water heating in the Northeast, applications, market barriers and a forecast for the future. The presentation introduces the different solar thermal programs that KeySpan offers including domestic hot water, pool heating, space heating, process hot water and solar assisted cooling. It also mentions the different applications where all this solar thermal energy can be used and what type of savings will be seen.

Canada Shines With Solar Expertise (2010)

Submitted by Raquel Ponte Costa on June 13, 2015

This paper was released by Foreign Affairs and International Trade Canada in 2010. The Vancouver Olympic Games showed large-scale success of solar thermal energy in Canada. Solar thermal modules supplied energy that supplied the Vancouver Olympic Village buildings and utilized it for other purposes. Estimates say that the buildings achieved 30 to 70 percent greater energy efficiency compared to standard buildings built to minimum code.

Italy: First Solar District Heating System, 990 m² big

Submitted by Baerbel Epp on June 1, 2015
VareseFinally, solar district heating has reached Italy too: Utility Varese Risorse, which is part of the environmental multi-utility group A2A, brought its solar thermal plant into operation on 19 May. The idea for this project, which also came about thanks to support from Intelligent Energy Europe project SDHplus, was from 2013 when the utility began to show interest in using solar to lower the natural gas consumption of its district heating grid in summer. Staff members of Varese Risorse took part in the SDHplus training course and benefitted from initial feasibility calculations for the solar plant. The collector field of 990 m² has been set up across eight collector rows, seven of which were mounted onto the ground, and one onto the roof of a small technical building, which also houses the heat exchanger and the control unit (see photo).

Submitted by Raquel Ponte Costa on May 30, 2015

This report was created and published by the Partners for Climate Protection (PCP). It highlights an important and successful greenhouse gas reduction project from the town of Okotoks, the Drake Landing Solar Community.

IEA SHC Task 52: Seeking Cost-optimised Urban Energy Systems

Submitted by Baerbel Epp on May 30, 2015
How can solar energy be ideally integrated into an urban energy system? This has been the key question of IEA SHC Task 52: Solar Heat and Energy Economics in Urban Environments. One and a half years after the task´s start in January 2014, scientists from Germany, Denmark, Austria and Switzerland met in Freiburg for the third task meeting in mid-April to discuss cost assessments of existing plants and models for analysing complex urban energy systems. One of the first published outcomes is a study carried out by Austrian research institute AEE INTEC. It lists the costs of existing solar district heating plants in Denmark, Germany and Austria. The chart shows the preliminary results from levelised heat costs calculated for 29 collector fields of sizes between 500 and 55,000 m² integrated into district or micro grids.
