    <p>The difficulty of converting measured weather data to an epw
      depends a lot on how complete are your data.  For a usable
      simulation weather file, you need these six key parameters -
      temperature, humidity, wind speed and direction, global horizontal
      and direct normal solar radiation.  The solar radiation is
      generally the most problematic.  There are various models that
      calculate solar radiation from other climate parameters, esp.
      cloud cover, but there are not many publicly-available programs
      that have them.  Also, cloud cover requires human observation or a
      dedicated laser and is almost never recorded at typical weather
      monitoring stations.  Lastly,  you have to make sure that whatever
      program you use interpolates in case there are missing
      observations in your data stream.</p>

                    <br>
                  </div>
                  I have measured on-site climate data and stored them
                  in an excel sheet.<br>
                </div>
                I want to use them in energy-plus for temperature
                prediction in the building.<br>
              </div>
              I don't know how to put them in an epw file in order to
              perform the simulation.<br>
              <br>
            </div>
            I will be happy to know that you can help me.<br>
