Step 4: Now determine the total heating and cooling energy needs for your home using the equations developed in class for thermal envelopes. Data for temperatures and wind conditions can be obtained on the web (monthly averages are sufficient)

The total heating and cooling energy needs of our home for an entire year can be found using the equations discussed in class for thermal envelopes:


c_p= 0.241 BTU/(lb*F) for air


Q_Heat= (UA + m_dotc_p)HDD = 65.7 x 10^6 BTU per year = 2.2 kW


Q_Heat =65.7 x 10⁶ BTU per year = 2.2 kW


Q_Cool=(UA + m_dotc_p)CDD + Qlatent = 7.36 x 10^6 BTU per year = 0.25 kW
