(TI-59) Solar Architecture
An excerpt from Solar Architecture the direct gain approach, MIT, McGRAW-HILL BOOK COMPANY, pgs. 161-181
Appendix 1 TI 59 PROGRAMMABLE CALCULATOR CODES Interior Air Temperature Swing 161-165 Solar Angles and Radiation 166-172 Average Daily Radiation III 173-181 PROGRAM DESCRIPTION(s): Given a data base, the program calculates the 24 hour average and min-max indoor air temperature for a single zone heated directly by the sun when the storage mass is either dominated by radiative or convective coupling. Internal gains and nighttime window insulation are not modeled. Only south facing windows can be modeled. Given a data base, the program calculates beam, diffuse, and total radiation upon and transmitted through a specified plane. Radiation values are given for clear sky conditions on the 21st day of the month specified. Optional output includes hourly values for solar altitude, azimuth, angle of incidence, beam and diffuse (ground plane and sky vault) radiation. Optionally, these values may be obtained for any time and day. Calculations are from ASHRAE procedures for incident radiation values. The user may specify solar time or standard time. This program does not compensate for cloudiness or shading. Given a data base, this program calculates the average daily insolation striking a surface of any orientation. The daily radiation is broken down into its beam, diffuse and reflected components, in order to facilitate determining the quantity transmitted through a glazing system. User Instructions, Sample Problem, Program Listing etc is included. BEST! SlideRule |
