Abstract [sv]

I Sverige arbetar i dagsläget ca 930 000 personer inom industrin. Inom industribranschen är det ofta fokus på direkta energiekonomiska vinster och inte på de vinster som görs indirekt. Detta gör att komfortaspekter som bra ventilation, ergonomiskt ljus och estetiskt tilltalande miljöutformningar inte prioriteras. Dagens industrier har ofta varierande flexibla layouter för att optimera sina processer. Det vill säga att arbetsstationer, maskiner och lagerhyllor flyttas för att gynna flödet för specifika produkter. Vid variation i layouten kan belysningen påverkas negativt om den om fast monterad. Genom en benchmarkingstudie samt ljusberäkningar undersöktes det i vilken utsträckning en fast belysningsinstallation kan vara lämplig för en industriverksamhet med varierande flöde. Resultatet av en del i studien visar att en fast belysningsinstallation, där armaturerna har bred spridningsvinkel, fungerar bra i industriverksamheter med varierande flöde. En experimentell studie med 17 deltagare genomfördes i en industrilokal för att undersöka i vilken utsträckning trivsel påverkas i en industri med god ljuskvalité, jämfört med en anläggning med sämre ljuskvalité. Undersökningen pågick under fyra veckor genom att två belysningsinstallationer utvärderades med hjälp av en enkät. Anläggningens befintliga belysningsinstallation jämfördes med en belysningsinstallation av bättre teknik och ljuskvalité. I den här delen av undersökningen framkom det att i ljuset med högre kvalité upplevdes naturligare, mer fokuserat, varmare och behagligare än i ljuset med lägre kvalité. Andra aspekter, såsom skuggbildning och reflektion, upplevdes relativt lika under alla undersökningsveckorna. Genom att upprätta LCC-kalkyler samt beräkna LENI-tal kunde det fastslås hur anläggningens energikostnad påverkas med en ny belysningsanläggning bestyckad med LED. En ljusanläggning med den nya tekniken har en lägre energianvändning än den äldre installationen. Detta bidrar till en mer ekonomisk och miljömässig hållbarhet.

Abstract [en]

Today, Sweden employs about 930,000 people in industry. In the industrial sector, there is often a focus on direct energy-economic gains and not on the indirect gains. This means that comfort aspects such as good ventilation, ergonomic light and aesthetically pleasing environmental design are not prioritized. Today's industries often have varied flexible layouts to optimize their processes. That is, workstations, machines and storage shelves are moved to favor the flow of specific products. If the layout is varied, the lighting can be adversely affected if it is permanently mounted. Through a benchmarking study and light calculations, it was investigated to what extent a fixed lighting installation might be suitable for an industry with varying flow. The result of a part of the study shows that a fixed lighting installation, where the luminaires have wide diffusion angle, work well in industrial operations with varying flow rates. A quantitative study of 17 participants was conducted in an industrial room to investigate the extent to which well-being is affected in an industry of good light quality, compared with a poorer light quality facility. The study was conducted for four weeks by evaluating two lighting installations. The system's existing lighting installation was compared with a lighting installation of better technology and light quality. In this part of the survey it was found that the light of the higher light quality perceived more natural, more focused, warmer and more comfortable than in the light with lower light quality. Other aspects, such as shadowing and reflection, were experienced relatively similar throughout the extent of the research. By establishing LCC calculations and calculating LENI numbers, it could be determined how the energy cost of the plant is affected by a new lighting system with LED. A light facility with the new technology has a lower energy consumption than the older installation. This contributes to a more economic and environmental sustainability.
