A Matlab template has been provided on D2L which provides the necessary constants to calculate the temperature at 1 second intervals for a single day, in a 200o square foot house.
Use the provided constants in the Matlab template to set up a for loop as outlined above which will calculate the temperature at each time step.
Store these values in the vector “T_in”
Plot time vs internal temperature
Calculate in seconds how long the furnace has run on this day, store this as “time_on”

T_out=15;  % Outdoor temperature in F
C= 3240; % Thermal Capacity of the Home, BTU/F
R= .002415; % Thermal Resistance F per BTU/h
time=0:1:24*60*60;  %A time vector, one day in seconds
T_in=zeros(1,length(time));  %Initializing an indoor temp vector
T_in(1)=70; % Setting initial temperature to 70F
K=90000; %Heat rating of the furnace in BTU/h
u=0;
time_step=1/(24*60*60); %Time steps in hours
T_H=T_in(1)+.25;  % High temp theshold
T_L=T_in(1)-.25;  % Low temp threshold
count=0;  %Initializes a count of how many seconds the furnace is on
