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.

New Zealand: Prized School Air Heating Project

Submitted by Baerbel Epp on November 26, 2016
Solarventi New ZealandA New Zealand research project which deployed solar air collectors in schools to improve pupils’ health while reducing heat costs has garnered an award by the New Zealand Institute of Building this year. Robyn Phipps, Professor in Construction at Massey University’s School of Engineering and Advanced Technology, won the award for her research project conducted in cooperation with the Australian subsidiary of Danish air collector manufacturer Solarventi. The project led to the installation of solar air heating systems in ten classrooms of five primary schools in wintertime in 2013 and to the implementation of another batch of systems in 12 classrooms of six primary schools the following winter. Monitoring data showed that attaining similar temperatures in the control classrooms required 2.5 times the thermal energy used in the solar-heated ones.

Solar Electric and Solar Thermal Energy: A Summary of Current Technologies (2014)

Submitted by Francesco Gattiglio on June 26, 2015

This document, written by Tayyebatossadat P. Aghaei of the Global Energy Network Institute (GENI), illustrates the different applications of solar thermal and photovoltaic technology. 

After a brief introduction on the history of solar energy, the document firstly explains the functioning of large scale solar thermal technology systems, differentiating between flat-plate collectors and concentrator collectors. This section includes also graphic representations of the different systems.

Solar Thermal Heating (2009)

Submitted by Raquel Ponte Costa on June 21, 2015

This brochure was created by CareyGlass Solar. It explains how solar thermal water and air heating function, and the various technologies that make this possible.

The report details how solar thermal collectors are able to capture the heat of the sun and then pump that energy through a home’s air or water heating systems; there is a diagram to demonstrate this process. From here, the brochure explains how to properly fit and select collectors based on a home’s needs, and whether evacuated or flat plate is the proper collector type.

Clean Energy Action Plan Towards 50/50 by 2020 in the Bega Valley Shire (2007)

Submitted by Raquel Ponte Costa on June 20, 2015

Clean Energy for Eternity, Inc. provides this thirty-seven page document to promote and stimulate relevant bodies to take appropriate action to reduce energy use and develop local clean energy generation projects.  The use of solar energy is a large portion of what the Clean Energy working group suggests as these “appropriate actions”.

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.

Solar Thermal Case Study: Shouldice Hospital (2012)

Submitted by Raquel Ponte Costa on June 14, 2015

This case study was written by by Gemco Solar. It profiles a solar thermal water heating and air cooling and heating system they installed on the Shouldice Hospital in Thornhill, Ontario, Canada.

Conceptual Design of a Solar-Thermal Heating System with Seasonal Storage for a Vashon Greenhouse (2006)

Submitted by Raquel Ponte Costa on June 13, 2015

This is a thesis research paper from the University of Washington in 2006. The objective of the study is to design a solar thermal heating system with seasonal storage for a greenhouse, optimized for the environmental impact, thermal efficiency and cost. The main goals of the study is to: provide 100 percent solar heat to the greenhouse; limit the size of the storage to fit within the footprint of the greenhouse; minimize environmental impact and cost; maintain greenhouse temperatures ideal for optimum growing; maintain historic greenhouse structure.
