I'd switch from Chuze Fitness in a heart beat!!! If you think that the transmission, or solar radiation, is significantly important to the total amount of the heat gain, it could be recommendable to use dedicated software, like Hourly Analysis Program (HAP), by Carrier. From a design-engineering perspective, there are two important implications: The ASHRAE Heat Balance Method states that the sum of all space instantaneous heat gains at any given time does not necessarily (or even frequently) equal the cooling load for the space at that same time. You will be redirected once the validation is complete.

When predicting annual building energy/cost/carbon performance, we do not encourage this approach and use hourly operational profiles instead. 1 Temperatures are degrees Celsius (Fahrenheit), to be maintained at +/-1 C (+/-2 F). Internal heat gains from plug loads are a significant portion of those calculations, explains ASHRAE. Equipment heat gain is often small at space temperatures above approximately 1C. This process is automatic. Keep in touch with your committee or group by accessing its home page! As CDA suggested, a professional is a way to go in this situation. * Roof intakes must be at least 0.2 m (8 inches) above the average maximum snow depth and the potential for drifts at the intake location must be considered. .
