Air infiltration through revolving doors may have significant impact on the heating load of commercial and institutional spaces, and may create discomfort to people. This paper modifies a 40-year old model by Schutrum et al. (1961), composed of two components:
(1) estimation of air exchange between one segment of the revolving door and the indoor/outdoor,
(2) estimation of net air infiltration rate.
A program is presented which runs on Apricot, Sirius and IBM-PC microcomputers and calculates the heating energy requirements of single zone, intermittently heated buildings with reasonable accuracy. Calculation of preheating energy is based on the average internal temperature concept of CIBS Energy Code 2. Solar gains and long-wave radiation losses are treated crudely on the basis of regression equations for radiation as a function of daily average external temperature for different periods of the day.
Measurements were carried out on the heating and airing habits of the occupants of several flats. 9 flats in a 6 storey building in Berlin, using various ventilation systems were studied. Two of the flats also had an air heating system.
Lists the HOTCAN computer program devised for use in the Division of Building Research (NRC) program on low energy houses. It is written in BASIC and is capable of estimating the space heating requirements of residences. Gives basic equations and assumptions, and weather data required, along with a listing of the program and a sample run.
Describes a computer program, Harmon, developed for the simulation of the thermal response of buildings (based on BRE's "admittance procedure") which can be used on mini-computers and utilized at the sketch design stage for the comparative evaluation of alternative designs. Gives an account of the validation exercises completed and outlines further intended refinements.
