Performance Prediction of Direct Gain Passive Solar Buildings for Danish Climate Conditions

摘要

The architect can employ three basic approaches to save energy. Passive solar design is one of them. The SLR simplified computerized method is at present the most widely used method in the world. A typical residental house in Denmark has been analysed to show the potential of Los Alamos III, the latest version of SLR correlation procedures. Analyses Method for the Construction Document Phase was used to predict a monthly and yearly auxiliary energy consumption for space heating. Over 100 options were examined by changing the basic passive solar design parameters. The results were compared to the results obtained by BA4 and BLAST, two large computer programs. BA4 and Los Alamos III show good agreement, BLAST and Los Alamos disagree significally. Some discrepancies were found in Los Alamos procedures. With some modification, the Los Alamos simplified method can be strongly recommended to the designers. (ERA citation 10:027265)
