Assignment No.2


A. OBJECTIVE


A government-based agency has to approve the plan for energy supply of about 15,000


new houses in Quebec. Each house has average energy consumption for heating of


30,000 kWh/year. Among the many criteria to be considered, the agency is evaluating


the greenhouse gas emissions. The agency has received the following proposals:


Proposal No. 1, Received from the electrical utility company (off-site energy source)


The electrical utility company has proposed to build a new power generating facility to


cover the expected demand. The power generation plant can have the following three


design alternatives:


1. Hydro run-on-river


2. Thermal plant using heavy oil as the primary energy source


3. Thermal plant using natural gas as the primary energy source


Proposal No. 2, Received from a different utility company (on-site energy source)


Another utility company has proposed to distribute the energy source directly to each


new house, using:


1. Natural gas


2. Oil





B. YOUR TASK


Your company has been hired by the government-based agency to estimate the


greenhouse gas emissions of the above design alternatives and options. You are asked to


recommend the plan of action based on the analysis that will lead to the minimum


greenhouse gas emissions over the life cycle of houses of 30 years.





C. CALCULATIONS AND DESIGN PROCEDURE


1. Use the information from all lectures posted on the course website. If some


information is missing, make your own assumptions based on the referenced


publications or other web sites.


2. Calculate the equivalent-CO2 emissions due to the heating needs of the houses for


each design alternative and option [tons/year], using one of the three methods


presented in the class and website.


3. Calculate the equivalent-CO2 emissions due to the heating needs of the houses for


each design alternative and option, over the life cycle of 30 years [tons].


4. Recommend the “design option” that is expected to produce the minimum


greenhouse gas emissions.


5. Compare the results of your recommended “design option” with the total


emissions of your preferred car over the same period of 30 years. Assume that


you are driving about 15,000 miles/year. How many cars will equal the total


greenhouse gas emissions calculated above?


E. PRESENTATION OF THE ANALYSIS AND THE FINAL REPORT


Your report must contain the following:


1. Cover page containing: course number and section, your name and I.D. number,


date of submission, and the instructor name.


2. All formula used in the calculations.


3. Numeric values of each variable used in the formula.


4. Set of calculations for each design alternative.


5. Final results with the appropriate units.


6. Source of assumptions and values used in the calculations.


7. Justify your recommendation for the “design option” selected (item No. 4 of the


above procedure).
