Objective
THE PROJECT PASSYS IS A EUROPEAN CONCERTED ACTION IN THE FIELD OF PASSIVE SOLAR COMPONENT AND SYSTEM TESTING. THE PASSYS GROUP IS COMPOSED OF THOSE TEAMS WHICH WERE SELECTED AMONG APPLICANTS TO THE R&D CALL FOR PROPOSALS NUMBER C69 OF 16 MARCH 1985.
THE GENERAL OBJECTIVES OF PASSYS ARE THE FOLLOWING:
- TO INCREASE CONFIDENCE IN PASSIVE SOLAR SIMULATION MODELS AND DESIGN TOOLS WHICH HAVE TO BE FURTHER DEVELOPED AND VALIDATED
- TO DEVELOP RELIABLE AND AFFORDABLE TEST PROCEDURES FOR PASSIVE SOLAR COMPONENTS AND SYSTEMS.
THE PROJECT PASSYS IS A EUROPEAN CONCERTED ACTION IN THE FIELD OF PASSIVE SOLAR COMPONENT AND SYSTEM TESTING. THREE FRENCH LABORATORIES PARTICIPATE TO THE PROJECT: THE CENTRE SCIENTIFIQUE ET TECHNIQUE DU BATIMENT, WHICH IS THE LEADER LABORATORY, THE ECOLE NATIONALE SUPERIEURE DES MINES DE PARIS AND THE CENTRE D'ETUDES NUCLEAIRES DE CADARACHE. THESE LABORATORIES ARE INVOLVED IN THE METHODOLOGIES-, VALIDATION- AND SIMPLIFIED DESIGN TOOLS ACTIVITIES OF PASSYS.
TWO ORIGINAL COMPONENT TESTING METHODOLOGIES ARE PROPOSED AND STUDIED BY THE FRENCH TEAM. THESE METHODOLOGIES ARE BASED ON THE APPLICATION OF MODEL IDENTIFICATION TECHNIQUES ALLOWING THE DETERMINATION OF THE VALUES OF MODEL PARAMETERS FROM THE MEASURED INPUT AND OUTPUT DATA. ONE OF THE METHODS INTRODUCES A 9-PARAMETER DYNAMIC MODEL, THE OTHER ONE A STATE-VARIABLE MODEL. THESE TWO METHODOLOGIES, TOGETHER WITH THE MORE CLASSICAL INTEGRATED SUBSTRACTIVE METHODOLOGY, ARE CURRENTLY TESTED ON THE THREE PASSYS TEST-CELLS AVAILABLE IN FRANCE IN ORDER TO PRECISE THEIR ABILITY TO PROVIDE STEADY-STATE AND/OR TRANSIENT-STATE COMPONENT CHARACTERISTICS.
CONCERNING THE VALIDATION AND DEVELOPMENT OF THE ESP SIMULATION CODE CHOSEN BY PASSYS AS A REFERENCE FOR ITS WORKS, THE FRENCH TEAM IS PARTICULARLY WORKING ON THREE TOPICS: AIR MOVEMENTS, PASSIVE COMPONENTS AND THERMAL MASS. ABOUT AIR MOVEMENTS, ALGORITHM ANALYSES AND COMPARISONS WITH OTHER CODES HAVE NOT SHOWN PARTICULAR PROBLEMS, EXCEPTED THE LARGE COMPUTING TIME NEEDED FOR PERFORMING SIMULATIONS WITH THE AIR-FLOW DETAILED MODEL. A SIMPLIFIED MODEL OF HEAT TRANSFERS DUE TO VENTILATION IS UNDER DEVELOPMENT. SIMULATION EXERCISES CARRIED OUT ON COMPONENTS HAVE REVEALED SOME QUESTIONS AND POSSIBLE IMPROVEMENTS NEEDED ON SEVERAL POINTS.
THE OBJECTIVE OF THE SDT SUBGROUP (LED BY THE CSTB) IS TO DEVELOP WORKS IN ORDER TO INCREASE CONFIDENCE IN PASSIVE SOLAR SIMPLIFIED DESIGN TOOLS. BESIDE SIMPLIFIED SIMULATION TOOLS OBTAINED BY MODEL OR DATA REDUCTION TECHNIQUES AND WHICH MAY CONSTITUTE A SOLUTION FOR DEVELOPING FUTURE MORE SOPHISTICATED SIMPLIFIED CALCULATION TOOL, CORRELATION BASED TOOLS APPEARED AS A PERTINENT PRODUCT TO BE DEVELOPED FIRST IN THE FRAME OF PASSYS. AS A MATTER OF FACT, SUCH TOOLS ARE CURRENTLY USED IN THE BUILDING WORLD QUITE WIDELY EITHER FOR REGULATORY OR PERFORMANCE ASSESSMENT PURPOSES. HOWEVER A LARGE NEED OF VALIDATION AND IMPROVEMENT HAS BEEN IDENTIFIED FOR THESE CALCULATION TOOLS. IT IS WHY PASSYS IS PRESENTLY CARRYING OUT WORKS IN ORDER TO BE ABLE TO PROPOSE AT THE END OF THE CURRENT CEC PROGRAM (MID 1989) A PRELIMINARY VERSION OF A VALIDATED (THROUGH ESP SIMULATIONS) CORRELATION BASED CALCULATION TOOL ALLOWING BUILDING HEAT REQUIREMENT AND PSC PERFORMANCE-ASSESSMENT, TOGETHER WITH AN APPRAISAL OF COMFORT DURING THE HEATING SEASON. SPECIFIC INVESTIGATIONS ARE PERFORMED IN ORDER TO DEFINE A PERTINENT CORRELATION PRINCIPLE AND TO IMPROVE SOME TOPICS NOT YET WELL TAKEN INTO ACOUNT IN THE METHODS AVAILABLE UP TO NOW: MULTIZONE EFFECTS, INTERMITTENT HEATING, PASSIVE COMPONENTS, BUILDING THERMAL MASS, TIME STEP, INSIDE TEMPERATURE REGIME, CLIMATE.
