Requirements
This course is designed for anyone with basic knowledge of low rise detached or semi-detached residential house, and basic computer skills: microsoft excel.
The students shall have a personnel computer with access to the internet and microsoft Excel to practise calculation..
The students need to have basic understanding of mechanical engineering knowledge with minimum grade 12 education
Description
This course explores the residential house HVAC design technique for typical detached, semi-detached and townhouse low-rise residential houses in Canada. The course includes both heating, Air Conditioning and ventilation (HVAC) load calculation, and prepare the basic knowledge for the HVAC air system design.The course starts by presenting the basic building elements and common types of low rise residential homes, and explain the method of calculating building foundation conductive heat loss, building envelope (exposed ceiling, roof, floor, wall, door, window and skylights) conductive heat loss and solar heat gain. The course further explores the occupants' heat gain and equipment heat gain, and the method for calculating ventilation and infiltration heating and cooling load.Through the Q & A section, the students will be provided with an excel template for load calculation and air system design of a sample home. The template is developed and used by the instructor who has successfully completed HVAC design for hundreds of residential houses across Ontario Canada. There are lots of load calculation formulas that will be included in the Microsoft Excel template for students to practise load calculation on their own. The air system design portion is also included in the temperate provided to the students in the basic course, but lecturing of the air system design will be left for the intermediate and advanced HVAC design course. Despite the template being developed is based on Ontario building code with specific energy efficiency and ventilation requirements in Ontario, and despite all the formulas being in the imperial (IP) format, this Excel template may be easily adopted for any geographic location across the globe. The parameter subsitution for all different climate zones will be explained.This course is offered to students worldwide, so all the calculations will be performed in both unit systems: IP (imperial) and SI (metric). The students will be encouraged to find out the winter and summer design temperature and indoor design temperature for the specific location of the subject house, as well as local building code, ventilation code and HVAC equipment energy efficiency requirements from the specific AHJ (authority having jurisdiction), and design the HVAC systems accordingly. In case the building code and weather date is not available for some climate zones or regions, the course will also provide the students with recommended minimum requirement data.Upon completion of this course, the students are expected to be able tounderstand house HVAC system, to perform basic load calculation, to size the HVAC equipment and to design the HVAC system accordingly for occupants' health and comfort living in their residential homes. The minimum ventilation requirement will be recommended to ontrol the indoor air quality for occupants' health.
Who this course is for
