This research explores the value that smart offices can provide to real estate investors. Through an extensive literature review a theoretical framework is created on the topics of smart technology, added value, the real estate investor and the real estate user. Then, three case studies are studied in depth by interviewing involved stakeholders. For each case an overview is created of what makes the building a smart building. Furthermore a connection is made between the smart technology and the way it contributes to the added values found through the literature review. In the end a Smart Value Map is created that connects smart technology, with added value and the main objectives of the investor. This way, by following the smart value map, smart technology is shown to provide value in various ways. It can improve the satisfaction of the users, it can increase the indoor environment, branding, culture. Furthermore, smart technology can be used to increase operational efficiency to reduce costs, increase adaptability and sustainability.
