2. What is Solar Water Heating?
Solar water heating involves converting energy from the sun into heat for water heating.
Wide variety of system types
Active and passive, direct and indirect

3. Problem
On StFX campus, domestic hot water is heated using steam that is generated in the Central Heating Plant
Steam is generated by burning bunker fuel which travels across campus in underground pipes
Overall efficiency around 69%, 10% of losses occur when the steam is travelling from the heating plant to its destination
Burning bunker fuel produces greenhouse gases and may not be sustainable

4. Project Goals
Design and conduct analysis on a solar water heating system for MacIsaac Hall to assist the current steam system
Examine the potential of solar water heating for MacIsaac Hall and estimate the initial costs, energy output, savings and reduction in emissions
Reduce the university's dependence on steam heated hot water and promote a more efficient heating process

5. Project Site MacIsaac Hall was recommended Southern exposure
Flat roof section
Bathrooms are located under the flat roof section

7. Challenges Decreased performance in winter months
Highest output of a solar energy system occurs in the summer, when the residence is empty
Size limitations due to available roof space
Integration with existing system

8. Existing Companies Thermo Dynamics Ltd. (Dartmouth, NS)
Doctor Solar (Dartmouth,NS)

9. Next Steps Further data collection
Hot water consumption, annual solar energy in Antigonish
Consult with local professionals and suppliers
Thermo Dynamics Ltd.
StFX Facilities Management
Continue to seek financing options for the project

10. Funding Government Funding Student Union Support
There are grants from the government, provincially and federally that vary from $25,000-$5 million that are open for applications. As well as the student Union funding that is up to $5000.

11. Software RETScreen Oberon
Clean energy management software developed by Canadian government
Use for energy analysis for the project as well as feasibility
Allows for manually entering specifics about the project (size, direct/indirect heating)
Gives summary of heat delivered and solar fraction
Shows month to month average temperatures, humidity, etc. for locations all over Canada
Oberon
Currently used by StFX Facilities management
In depth energy analysis of all buildings on campus
Shows total energy and power usages and monitoring on campus
