1. Reasons For Selection
Theoretical Position In Radauti, Romania the modular office building was aimed to be an energy-efficient construction with timber as a primary material which was implemented sustainably. Here, the vitality of the copper facade stands in contrast to the homogeneous timber interiors. Designed by architect Bruno Moser - the building recieved the Gold Seal Certification DGNB. Relation to Studio Project Studio project also deals with a modular construction. The studio project also uses a combination of construction methods from in-situ concrete with possibly a steel structure. The studio project also deals with prefabrication of elements and standardized fittings significantly reduce construction time. Aims to be sustainable by using locally sourced materials by reducing the carbon offset.

Foundations The building has foundations of in-situ concrete spaced 11500m apart. They transfer the loads from the primary structure to the ground. The Plant room under the entrance space has a retaining wall and pad foundation system Primary Structure The primary structure comprises of RHS columns and Steel I beams joined together at the ends of the building, these are concealed by partition walls. This creates office spaces that are not interrupted by columns. The Primary Structure also accommodates for the services running through the building in which case the I-beam does not extend to the Tertiary column, only C section beams join the Tertiary column.
Primary structural system 1:500 R.H.S Columns
Box Beams The box beams act as the primary floor structure of the building supported at its corners by the C-section beams that sit within the I-beam. Each office space is made up of five box beams measuring 11400x2800x520, which are ideal for the OSB boards. Bracing Members Bracing members provide additional support from earthquakes and are located between two RHS columns.
3. Environmental Design Study Service Distribution 1:500 Exhaust heat exchanger Electricity and Water Distribution
The Design Principle The basic design principle was focusing around the idea of sustainability and complete prefabrication of most elements. All the sizes are standardized based on local availability, and have consequently impacted the modular design, considering the potential into the expansion of the building. Service Distribution The building has a modular design with integrated service cores that run along the gap created by the two RHS Columns of the structure at specified intervals to carry service pipes (electricity, water and heating). These are then distributed to the plant room through a trench system under the building. An exhaust heat exchanger is located outside the building which is used to heat the building.
Individually Regulated Office modules 1:500
Office Spaces Combined heat and cooling ceilings account for 60% of the heating, while the other 40% is under floor heating that can be regulated by the employees themselves. Each of the 160m2 office spaces has been integrated so that they are capable of individually regulating the micro-atmospheric conditions. Plant room The distribution of the services is so organized that the plant room is located under the entrance (central core) of the building which is ideal as it accommodates for the requirements of the buildings users.

5. Reflections on Detail Development Some of the most crucial developments of the case study surrounded the connection between the steel I beams and the RHS columns to leave room for the services. After careful consideration and research this was resolved to highlight the presence of a C-section beams that extend from the steel I beam to the tertiary column. Which leave room for the services to pass. There was also an issue regarding the accurate location of the service cores due to the plans being at a very poor resolution, this was later deciphered by analysing the requirements of each office space and deducing the locations of the restrooms and services. The lack of relevant sections made it difficult to understand the relationship between the box beams and the steel I beams but it was later realised after viewing photographs that even though the box beams are deeper their corners converge to rest within the gap of the C-section beams.
