LUUKKU-HOUSE LIFE CYCLE ANALYSIS
• THE LIFE CYCLE ANALYSIS FOR LUUKKU - HOUSE BY
RESEARCHER SIRJE VARES, VTT
SIRJE VARES: LCA AND CARBON FOOTPRINT FOR LUUKKU HOUSE.
04.02.2010. RESEARCH REPORT. VTT
• ARCHITECTURAL AND STRUCTURAL DESIGN IS BASED ON THE USE
OF WOODBASED MATERIALS WHENEVER POSSIBLE.
LUUKKU-HOUSE LIFE CYCLE ANALYSIS
INCLUDED IN LCA:
• RAW MATERIAL ACQUISITION
• RAW MATERIAL TRANSPORTATION
• PRODUCT PRODUCTION
NOT INCLUDED:
• MATERIAL TRANSPORTATION TO THE SITE
• CONSTRUCTION
• USE, MAINTENANCE, CARE
• END OF LIFE TREATMENT

house. 04.02.2010. Research Report. VTT
THE LIFE CYCLE ASSESSMENT OF THE CONSTRUCTION MATERIALS
SHOWS A TOTAL CARBON FOOTPRINT OF 15 000 KG AFTER THE HOUSE
IS COMPLETED. THE CARBON STORAGE OF THE RENEWABLE BUILDING
MATERIALS IS 26 500 KG.

SOLAR GAINS ARE SMALLER
IN NORTHERN EUROPE
COMPARED TO SOUTHERN
EUROPE DUE TO LESS SUN
HOURS AND A LOWER
SOLAR ANGLE
HOWEVER, IT SEEMS THAT
SOLAR POWER COULD BE
MORE WIDELY UTILIZED
EVEN IN THE NORTHERN
HEMISPHERE
INTERFACE SOLUTIONS
ENERGY PRODUCTION AND CONSUMPTION, WEATHER STATION INFORMATION
AND THE PHYSICAL PERFORMANCE OF THE FINISHED BUILDING ARE ALL MONITORED USING CONSTANT, REAL-TIME METERING. ALL INFORMATION IS AVAILABLE THROUGH ONE USER INTERFACE, ON THE INTERNET.
