SEE705 Energy Efficiency and Demand Management

Task:

Question 1: 

Assume that you are working as a building engineer in a company. You have been asked to determine the heat loss per unit area (in square feet). The client is from the Greater Geelong area and this client is particularly interested to calculate the heat loss during the winter season.  

 The company has received the following information from a client:

For this calculation, you can assume the reasonable temperature condition in the Greater Geelong area. 

As a part of this process, you need to calculate the following:

a)Determine the U-factor for both cavity and frame 

b)Calculate the heat loss per unit area for the cavity and frame 

c)Determine the U-factor of the overall envelop by considering 30% as the frame and remaining as the cavity

d) Calculate the overall heat loss per unit area by considering an envelope having 30% frame with remaining as the cavity.

Question 2

You have been given the operating information of a boiler

a)Determine the fuel savings for the nominal operating condition 

b)Determine the fuel savings when the exhaust gas stack temperatures are reduced and increased from the nominal value. You need to assume the reasonable temperature. Also, comments on the results.

c)Determine the fuel savings when the amounts of Oxygen are reduced and increased from the nominal operating condition. You need to assume the reasonable amounts of Oxygen. Also, comments on the results.
