Title: Passive solar calculation methods. Final report
Abstract: An analytical treatment related to the generation of space specific weighting factors is presented using a recursion relationship which employs a heat balance of both the outside and inside surface. After which the multizone problem is discussed, the analysis of which is facilitated through the use of the calculated weighting factors. The use of frequency domain methods is detailed such that the amplitude ratio and phase shift characteristics for a sinusoidal excitation are derived for the thermal load resulting from radiation heat gain/loss and space air temperature fluctuations. The results of a parametric study related to variable floor properties, radiation distributions and space sizes are presented. The weighting factors generated for each perturbation were used to define the expected differences in space response characteristics. Additional studies made using methods available for use in calculating thermal loads without the program peculiar aspects inherent in the first comparison. The Appendix, in addition to containing the tabulated results of the parametric study, also includes a specific discussion for each of the tasks outlined within the statement of work.
