Design Calculations for Passive Solar Buildings by a Programmable Hand Calculator

The behavior of room temperature in a passive solar building without backup heat is of great interest to the building designer. This Daper presents programs for card-reading programmable hand-calculators which compute room temperature over the course of a design day. Instructions for calculating the input parameters, and for running the programs are given, and a brief review of the theory is provided. The program can presently be used only for single-zone unmanaged, direct-gain buildings.
