Abstract [sv]

Belysning är ett stort behov i vårt dagliga liv. De senaste åren har utvecklingen inom belysningsområdet uppnått markanta förbättringar gällande energiförbrukningen, ljusstyrkan, miljöaspekten och livslängden för ljuskällor. Äldre belysningsanläggningar fasas ut och ersätts numera med LED-lampor.

Examensarbetet har som grund att energieffektivisera en belysningsanläggning för en lokal i Göteborg med en area på ca 220kvm som består av 12 rum. Arbetet har skett hos uppdragsgivaren Ljusproffsen Future Group Svenska AB som har fått förfrågan av kunden att förnya belysningsanläggningen till LED. Bytet till LED har som mål att bidra med en ekonomisk besparing för kunden.

En inventering av alla ljuskällor i lokalen har tagits fram med en beräkning på den totala energin som förbrukades. Därefter har en ny belysningsritning tagits fram med hjälp av beräkningsprogrammet för belysning DIALux evo samt den reducerade energiförbrukningen som kan åstadkommas. LED-belysningen täcker alla krav som är satta av arbetsmiljöverket gällande arbetslokaler och kontor.

Energiförbrukningen har sänkts från att ha varit ca 2844W till 1581W. Det motsvarar en minskning på 44%. Den årliga energiförbrukningen uppskattas att vara 6 324MWh baserat på 4000 timmars belysning per år. Livslängden för LED-anläggningen är 50 000 timmar för de valda armaturerna jämfört med dem tidigare som är 20 000 timmar. LED-lampor bevisar sig att vara ett bra val för energibesparing. Det totala armatursljusflödet för hela lokalen har ökat med 21 000lm.

Abstract [en]

Lighting is a big need in our daily lives. In recent years, the field of lighting has achieved significant improvements in energy consumption, brightness, environmental aspects and the lifetime of light sources. The outdated lighting systems are phasing out and are now being replaced by LED lamps.

The thesis is based on establishing a more energy efficient lighting installation for an office premises in Gothenburg that has an area of 220 sq.m. and consists of 12 rooms. The work has been carried out with the entrepreneur Ljusproffsen Future Group Svenska AB, which has received a request from the customer to upgrade the lighting system to LED. The replacement to LED aims to contribute to a financial saving for the customer.

An inventory for all light sources in the office premises has been established with a calculation of the total energy consumed. After that, a new lighting layout has been proposed using the DIALux evo lighting calculation program and the reduced energy consumption that can be achieved. The LED illumination covers all the requirements of the Occupational Safety and Health Act regarding workplaces and offices.

The energy consumption has been reduced from approximately 2844W to 1581W. This corresponds to a decrease of 44%. The annual energy consumption is estimated at 6 324kWh based on 4000 hours of lighting each year. The life of the LED installation is 50,000 hours for the selected luminaires compared to the previous ones which have a lifespan of 20,000 hours. LED lights have proved to be a good choice for saving energy. The total luminaire light flow for the premises has increased with 21 000lm.
