The field of building services and the topic of interior user-centric climate has been gaining on importance in recent years. The pandemic of COVID-19 has resulted in an increased amount of time spent indoors, extensive energy usage in the built environment, and has also brought up the important issue of a pleasant interior climate. These two implications have become prominent on top of the ones resulting from the existent, persistently growing threat which is posed on our planet by climate change. Rising temperatures & increasing amount of sunlight, extensive energy consumption due to higher demand for cooling and heating, especially in large buildings (i.e. office buildings) occupied by large amounts of people with different preferences and user habits - these are all challenges we now have to face. Considering these challenges, this thesis suggests how a holistic approach could protect against them, mitigate their further development and so prevent their future impact on us humans. The overarching goal of this thesis, the pursuit of the “ideal” interior climate in office buildings, is achieved through setting up scenarios where different variations of daylighting, thermal comfort and energy consumption will be experimented with. The “ideal” interior climate will then be determined through assessing these scenarios and their corresponding results, yielding a recommendation for building future office spaces - these will no longer be only functional and provide shelter, but will also support interior occupant comfort and be efficient while doing so.

The World Wide Web provides a well standing environment in any kind of organizations for exposing online products and services. However, no one ensures that web products or services which provided by organizations or enterprises, would receive the proper visibility and accessibility by the internet users. The process of Search Engine Optimization examines usability in design, architecture and content that an internet-based system has, for improving its visibility and accessibility in the web. Successful SEO process in an internet-based system, which is set under the paternity of an organization, ensures higher recognition, visibility and accessibility for the web services that the system provides to internet users. The aim of this study characterized with a trinity of axes. In the first axe, an internet-based system and the web services that provides is examined in order to understand its initial situation regarding its visibility and accessibility in the web. In the second axe, the study follows a user-centric approach on how and in what way the examined system could be improved based on its users’ needs and desires. After the encapsulation of needs and desires that the users expressed as regards the usability of the system in design, architecture and content, the third axe takes place. In the third axe, the extracted needs and desires of users are implemented in the under-examined system, in order to understand if its visibility and accessibility has improved in the World Wide Web.For the completion of this trinity of axes, the Soft Systems Methodology approach is adopted. SSM is an action-oriented process of inquiry which deals with a problematic situation from the Finding Out about the situation through the Taking Action to improve it. Following an interpretative research approach, ten semi-structured interviews take place in order to capture all the participants’ perceptions and different worldviews regarding of what are the changes that they need and desire from the examined system. Moreover, in this study, the conduction of three Workshops, constitute a cornerstone for implementing systemically desirable and culturally feasible changes where all participants can live with, in order to improve system’s visibility and accessibility in the internet world. The results indicate that the adoption of participants’ needs and desires, improved the levels of usability, visibility and accessibility of the under examined internet-based system. Overall, this study firstly contributes to expand the knowledge as regards the process of improving the visibility and accessibility of internet-based systems and their web services in the internet world, based on a user-centric approach. Secondly, this study works as a practical toolbox for any kind of organization which intends to improve the visibility and accessibility of its current or potential web services in the World Wide Web.
