1 USERTEC USER PRACTICES, TECHNOLOGIES AND RESIDENTIAL ENERGY CONSUMPTION P E R H E I S E L BERG I N S T I T U T F OR BYGGERI OG A N L Æ G

2 BEREGNEDE OG FAKTISKE FORBRUG I BOLIGER Fra SBi rapport 2016:09 (Figur baseret på data om ca parcelhuse)

3 ADFÆRD BETYDER MINDST LIGE SÅ MEGET SOM TEKNOLOGI Ens huse forskelligt forbrug: I helt ens boliger bruger nogle familier 2-3 så meget energi som andre Adfærd betyder en faktor 2-3 i forskel på energiforbrug Nyeste lavenergiparcelhuse: Bruger i snit halvt så meget energi som gennemsnitlige parcelhuse Teknologi betyder en faktor 2 i forskel for energiforbrug

4 USERTEC IDEA WE NEED TO KNOW MORE ABOUT THE USERS AND THEIR EVERYDAY PRACTICES: To actually gain the potential energy savings from new efficient buildings technologies To design technologies and buildings which in real live deliver attractive and healthy buildings that are easy to use and live in.

5 METODER I USERTEC 1. STATISKE ANALYSER BASERET PÅ REGISTER DATA 2. UNDERSØGELSE AF BEBOERES ADFÆRD OG BRUGSMØNSTRE 3. UNDERSØGELSE AF BEBOERES TEKNOLOGIANVENDELSE

6 SURVEY MED ANALYSE AF KOLLEKTIVE STRUKTURER BAG PRAKSIS

7 HOW OFTEN HAVE YOU AIRED (IN THE PAST TWO WEEKS)

9 RESULTS SUMMARIZED D OINGS RELATE T O BUILDING CHARACTERISTICS, F OR EXAMPLE People dress warmer in older buildings People keep higher temperatures in newer buildings People regulate thermostats less if they have underfloor heating S U R P R I SINGLY, AIRING HABITS D O NOT DEPEND ON BUILDING TYP E S. MAYB E BECAUSE T H E Y D E P E N D ON OTHER SOCIAL P R A C T I C ES LIKE B A T H I N G A N D COOKING.

12 A COMFORT PRACTICE ( ) UNDERFLOOR HEATING, I WOULD SAY IT IS LOVELY, IT IS WONDERFUL TO WALK AROUND ON THE WARM FLOOR, BUT IT, WELL THE RADIATORS, YOU CAN TURN THEM UP AND THEN THE HEAT COMES IN A SHORT WHILE, AND THE SAME WAY YOU CAN TURN THEM DOWN, AND IT WILL BE REGISTERED QUICKLY, THAT IS WHAT I HAD TO GET USED TO ( ) I THINK IT IS HARD TO CONTROL (LIS, 69) Kilde: Line Valdorff Madsen, PhD studerende, SBI, AAU

13 AFSLUTNING H OVEDPARTEN AF V O R E S E N E R GITILTAG ER R E T TET M OD E N E R GIEFFEKTIVISERING AF A P P A R ATER OG B YGNINGER og energi effektivisering er ikke det samme som energibesparelser Energieffektivisering er en effektiv adfærdskampagne den forkerte vej Brugeradfærd hænger sammen med teknologien og det skal tænkes mere ind i reguleringen for at opnå reelle besparelser Hvad andet kan vi gøre for at få reelle besparelser?
