With the need for excellent living standards to escalate day by day, the need to breathe good quality air remains of paramount importance for a prosperous, happy life. The indoor air quality picture is improving decade by decade. However, the importance of maintaining good indoor air quality remains unsatisfactory. Indoor air quality is one of the world’s most significant environmental problems. Statistics states that as of 2017, approximately 1.6 million premature deaths are caused by bad indoor air quality. The majority of these deaths result from the presence of Volatile Organic compounds in the air. VOCs are the common pollutants that are found indoors, which are not only toxic but also dangerous to health on long exposures. Even though several norms are put in place, why is the picture still persistent even after many technological advancements in the industry? This notion of this idea inspired the authors to conduct the current thesis. The thesis is based on a case study at a Swedish Air-cleantech company, Company-X, that developed efficient air filtration technologies to eliminate VOCs from the indoor air. However, for efficient diffusion of the technology, studying the market is of utmost importance. For this, the study is done by qualitative interviewing of professionals from the Swedish air filtration market. The interactions helped the authors to comprehend the more in-depth picture of influencing facets in persistent VOC issues in the indoor airs. Secondly,the meetings guided the authors with the industry choice for efficient technologies to eliminate VOCs from the indoor air. The collected data led to the conclusions that, various actors like awareness and buying decision factors, technologies are involved for VOCs still being a persistent issue in indoor airs. The industry’s awareness regarding Volatile Organic Compounds has been mediocre, and the significant factor for the buying decision is the price. Speaking of the technology, it has been reckoned that Activated Carbon filters are the best and economically efficient technology to eliminated VOCs from the air.

This study has been motivated by an understanding of the twin needs to reduce carbon dioxide emissions and increase the access to have complete control of the ventilation system available in the buildings. In consideration of the increasing utilization of fossil fuels, there is an extensive threat of increased global warming conditions associated. To ensure sustainable development, improvement of social welfare and wealth creation, energy is an essential factor. The consumption of electricity and energy delivered per floor area in Sweden has been considerably rising since 2014. The aim of this study is twofold where the authors have mapped and defined the specific customer needs for choosing an “add-on energy optimization module” for the existing HVAC systems in Sweden’s commercial market. Secondly, the study has also focussed to identify the acceptance of the complementary good technology from the perspective of a customer’s experience of value creation. It is a case study carried out in collaboration with a Swedish cleantech company, that will be named “Company-X” in the further part of the study. This company utilises a part of space technology to secure a healthy indoor air climate and at the same time save energy in buildings. The thesis has been carried out qualitatively. Since there is a preunderstanding of this theory where an abductive approach with semi-structured interviews has been followed to perceive the current market situation. The study further underlines the importance and need of making investments for a cleaning module combined with an optimization algorithm which can be easily mounted on current ventilation systems like Lego pieces. Under this module, the air quality is monitored, and the system adapts to current conditions concerning time. The results designate that it is possible to maintain a predefined indoor air quality to the lowest possible energy consumption by real-time monitoring with this cleaning module at facilities that are equipped with single or multiple-split HVAC systems. The best results towards attaining greater energy savings can be obtained from the association of Building energy management system and Air-handling unit with this cleaning module.

The aim of this thesis is to description and comparison of solutions, demountable connection of the lid and box enclosure air filters for motor vehicles, developed and used by the manufacturing concern MANN + HUMMEL, for which air filtration only one part of a broad portfolio of filtration systems for the automotive industry in the world scale. Another part of this thesis will be one of the chosen optimization methods of connection and implementation of alternative proposals design solutions, including the selection of the best solution, creating design calculation, 3D design, FEA analysis and prototyping of an alternative connection method laser sintering. When creating the optimization and design of alternative design solutions can count on the possibility that existing solutions are taking all possible factors and that the best alternative design proposals show an improvement over existing at the expense of all other cells throughout the development of the product.
