Welcome to my Blog site.

Feel free to put in as much imput about my topic as possible. There is so much information out there on HVAC design, that I could use other peoples opinions and views. I will in turn try and research your topics.

    I have recently come across a green HVAC issue that you may want to look into. For our Green Dream Home we would like to include a HEPA filter in order to have a very high indoor air quality, but I understand that this will increase the amount of energy that our HVAC system will require significantly. I would like to know how to get high indoor air quality with minimal gain in energy usage.

    PLANNING OUTLINE
    APPLIED RESEARCH REPORT
    EDDT 231

    PROJECT:

    Analyze and assess the existing HVAC system for a School District 73 building. Compare and contrast with modern HVAC techniques and equipment, and develop recommendations for improving efficiency and operating costs.

    METHOD:

    • Interview and have a meeting with Art Mc Donald, supervisor of School District 73’s maintenance department to establish a buildings HVAC system that we can analyze.
    • Interview Refrigeration Mechanics in School District 73 and private contractor Interior Plumbing and Heating.
    • Interview experts in HVAC design at HPF Engineering and Stantec.
    • Interview Walter Prescott, mechanical design instructor at Thompson Rivers University.
    • Assess the gathered data of the existing system and modern system and use the assessment as a basis for a HVAC design modification.
    • Assess cost of modification and see if system is cost effective.
    • Create a mechanical drawing for the modified HVAC system if necessary

    SPECIAL PROBLEMS:

    • Efficiency of building envelope (R-value)
    • Buildings location (north facing windows, exposure to sun, and wind)
    • Air quality
    • School District’s annual budget for maintenance improvements
    • Time allowance to modify HVAC system (2 months in summer)
    • Many different simple solutions for a more efficient system (economical)
    • Converting pneumatic controls to DDC controls

    ALSO:

    • Space allowed for preferred HVAC system (Mechanical Rooms)
    • Local contractors may not be familiar with new technology

    Dale,
    I did some research on the hepa filter system. It is by far the best air filtration system (99.97% of air born particles) but it is not energy efficient and could void warranty on the equipment. I believe the best alternative is a bypass hepa filter system that takes approx. 30% of cold air intake and has an internal fan that only uses max. 150 watts. this system has the energy efficiency with the air quality. I found that hvac-talk.com was helpful.

    Hey Denton! In one of the books I have on energy efficiency I came across some information on HVAC systems and it talks about what you can do to cut costs in your house. If you think something like that would be useful to you just let me know, the books called The Home Energy Diet.

    Meghan,
    Thanks for the book.The info. is applicable to my research project.

    For our 3rd year trip to Vancouver we toured the new convention center which uses green and economically freindly mechanical and HVAC systems. If you're still unsure of your topic you could look into bringing some of these systems into a building in Kamloops. Walter has the contact information of Mechanical technician who gave us the tour.

    Thanks Bryan,
    I will ask Walter about the contact information. It sounds interesting, and almost what my thesis question is. The only thing I don't know is if the HVAC system will work the same in our semi-arid climate. I hope so.

    Hey Denton,
    You might find this website on Energy Star Qualified
    HVAC systems by Lennox useful. Here's the link:
    www.lennoxcommercial.com/products/list_energy-star.asp
    Also you should check out this HVAC manufacturer Carrier.
    They have a subsidiary company called EMSI which deals primarily with green design.
