Heat consumption data supplied by: Henrik R. Hansen, Vestegnens Kraftvarmeselskab I/S, Roskildevej 175, 2620 Albertslund. Climate data supplied by: Svend Erik Jensen, Kulturteknik og Planteernæring, Institut for Jordbrugsvidenskab, KVL. Information on type of day etc.: Jørgen Olsen, Elkraft System, Ballerup Data preparation, outlier detection, etc: Henrik Aalborg Nielsen, IMM, DTU External sources of funding: Energistyrelsen (Energiforskningsprogrammet) ------------------------------------------------------------------ row.names: Row No. rdays: 'Running days', No. of days from the start of the data set (obs 1 = 0, obs 2 = 1/24, ...) Information on time: ds.: Indicates daylight savings time (MET DST), if '.ds' is omitted the time is in (MET = dansk normaltid). jdate: Julian date (No. of days since 1Jan1960) hh: Time of day (0,...,23) dow: Day of week (1=monday, ... , 7=sunday) tod: Type of day (1=Working day, 2=Half-Holy (incl. Saturday), 3=Holy (incl. Sunday)) diy: Day in year wiy: Week in year Climate at Taastrup (Ta.c,W.c,GR.c,Ta.f,W.f,GR.f): Ta: Ambient air temperature (degree C) W: Wind speed (m/s) GR: Global radiation (W/m2), on a horizontal plane, wavelengths 305-2800 nm .c: Indicates 'clean' data, i.e. original data in which "outliers" are set to missing (indicated by NA). .f: Indicates 'filled' data, i.e. '.c'-data in which NA's are replaced by appropiate values. The measurements are averages over the latest 10 minutes. Measurements from VEKS: Ta.VEKS.o: Air temperature (degree C), many outliers, may be influenced by solar radiation. HC.c, HC.f: Heat consumption (GJ/h) in the VEKS system (.c and .f as for climate). The measurement of heat consumption are the heat consumption over the last hour. ------------------------------------------------------------------ First row: Variable names No. of observations: 8782 Columns separated by "," (comma).
