Sweden has several environmental goals and one of them is to have net zero emissions from greenhouse gases. Emissions of greenhouse gases are strongly connected to usage of energy and 40% of the energy produced goes to buildings. A method of reducing energy usage is by using an energy audit and energy analysis.An energy audit and energy analysis has been done on a building in Stockholm. The building is 22165m2and consists of offices, laboratories and a restaurant, The aim of the study is to analyze the buildings energy usage with help of the energy audit and then find solutions that reduce the buildings energy usage. The method that has been used in this study have been a case study, observations, measurements and collections of data. A literature study has also been conducted to find potential solutions for reduction in energy usage that may be applicable to Apelsinen. To analyze the building observationswere conducted and information regarding energy usage and statistics where collected. Long term measurements were also conducted on power outlets and the indoortemperature. The energy analysis shows that there is big potential to reduce costs for energy usage by using cost efficient investments and by utilizing existing equipment and operating strategies. The study could show interesting results like that there where a big difference between the invoiced energy and the actual energy used. The study also discusses alternative solutions that might have been used and how they would affect the result like installation of a battery storage.If the proposed solutions are used the energy usage of the building can be reduced by around 392 MWh/year which results in a cost saving around 501 kkr
