Designing the entrance to an apartment building is often a complicated task due to the many demands placed on its design and construction. Everything from accessibility, safety during evacuation and fire safety, to the ability to follow the current local and zoning plan and finally, to look aesthetically pleasing and fit into the building's design language. The challenge becomes even more complicated when an entrance is to be developed as a module in a product platform where additional requirements are set based on the product platform's limitations and structure. This study maps out the requirements and presents an approach to developing an entrance module in a product system.   The purpose of the work was to design a concept for an entrance that can be manufactured as an entrance module similar to other modules in the customer's product platform. Today, they are usually built in a conventional way, i.e., on site with conventional building materials and techniques. The proposed solution must meet all legal and regulatory requirements, be able to be transported on the Swedish road network and meet all customer requirements. The module must also fit into the existing product platform.  The method used to design the entrance was to conduct interviews and workshops with experts. Benchmarking of existing entrance was done to analyze the construction. Their drawings were also studied and thematically analyzed. Concept generation was carried out continuously, resulting in a final concept.   The work resulted in a conceptually presented solution proposal that meets all legal and regulatory requirements and further customer and product requirements. The proposed solution is not fully developed when it comes to its design, i.e., the exact structure and construction needs to be designed in accordance with other modules in the product platform, before it is ready for production. However, the proposed solution contains all the critical dimensions, instructions, and reasoning for the various design decisions so that the detailed construction can begin immediately.

The purpose of this thesis is to investigate the possibility to build a modular data center in wood. The goals is to investigate how to build data centers using building system modules, making it easier to build more flexible data centers and expand the business later on. Investigations have been conducted to find out advantages and disadvantages for using wood in a modularized data center structure. The investigation also includes analysing the moistures effect on the material and if there are any other advantages than environmental benefits in using wood as a building material. A literature study were conducted to examine where research already have been conducted and how those studies can be applicable to this thesis. Although the ICT sector is a rapidly growing industry little research has been published in regards to how to build a data center. Most published information involves electric and cooling, not measurements of the building and how materials is affected by the special climate in a data center. As a complement to the little research interviews were conducted and site visits were made. Interviews were conducted with Hydro66, RISE SICS North, Sunet and Swedish modules, whilst site visits were made at Hydro66, RISE SICS North, Sunet and Facebook. As a result of these studies, limitations were identified with regards to maximum and minimum measurements for the building system and service spaces in a data center. These limitations were used as an input when designing a construction proposal using stated building systems and a design proposal for a data center. During the study, access have been granted to measurements of temperature and humidity for the in- and outgoing air of the Hydro66 data center. These measurements have been analyzed with the facts about HVAC systems and the climates effect on wood, for example in regards to strength and stability. This analysis has shown that more data needs to be collected during the winter and that further analysis needs to be conducted, to beable to draw conclusions if the indoor climate of a data center has an effect on the wooden structure. A design proposal for a data center have been produced with regards to the information gathered by the litterature and empirical studies. The proposal were designed to show how the information could be implemented. The result have increased the understanding on how to build data center buildings in wood and how this type of buildings could be made more flexible towards future changes through modularization.
