PO-Lab (Product Onwikkeling-Lab) or also known as PD-Lab (Product Development Lab) is a fully demountable sustainable structure which is constructed for creating a laboratory space for students in TU Delft Faculty of Architecture. The construction is made from OSB plates constructing box modules that should be able to be assembled by minimum 2 people. PO-Lab is aimed to diminish the problem of building waste and construction carbon footprint. DESIGN

The construction consist 3 main parts : floor blocks, wall blocks, and roof blocks. Each blocks are connected to each other based on friction-fit connection and bolts. The size of the blocks are constrained by the size of CNC-machine - in this case the maximum dimension is 2500 mm x 5000 mm. Furthermore, the way all the plates connected are intended to allow them to be durable yet also can be easily disassembled.
The connections are designed by Nick van der Knaap as a part of his graduation project in 2016. The design process managed to cover different variables and requirement - which signifies different parties in a project - such as assembly ergonomics, transport, efficiency in production, end of life cycle, etc.

STRUCTURAL PROBLEM The notches in the detail are able to maintain lateral force from the length axis. Yet, the lateral force from the width axis can cause domino-like displacement, since there is no connection between one block to the other. Therefore the research is based on solving the lateral load problem throught different component design which should also be assessed based on project goals - sustainability, user ergonomics, price, speed, etc. A scoring methodology is developed to assess all alternatives in the most objective way. The best alternatives are built into prototypes which is steel bolt for wall connection and butterfly joints for floor connection.

The main target of the project is to analyze and solve urban-scale energy problem in Dubrovnik, Croatia which is exarcebated by the rise of tourism. The solution itself is aimed to take as many aspect - such as social and economy aspect of Dubrovnik - into consideration. The result was presented in front of Dubrovnik municipality and was chosen to be one of the top three solutions. The given site was a depleted main hospital which is located in between two hills on the coast of Dubrovnik.

ENERGY ANALYSIS & MAPPING
27
In the initial phase, the energy production and consumption is mapped to show the area of energy potential. Based on the site research, the location of the hospital promises enormous amount of solar energy, due to the fact that it is the only building in that area. That diminishes the problem of tall buildings blocking each other’s solar harvesting area which also diminish the amount of energy harvested,
The solution is to integrate solar harvesting area in the hospital using green platforms. The platforms itself is aimed to improve the healing space of the hospital. The patients are given better surrondings and point of view while it absorbs sunlight.

There are 3 main loops which are connected to the hospital. These loops are tackling the main problem in Dubrovnik which is the energy used by transportation. First loop is the biomass loop. The great amount of vegetations and soil around the hospital can be used for heating and better insulation of the building. Second loop is connecting the solar farm to the electric bus system. The bus will act as a battery which travels around the city. It will carry the excess energy of the solar farm to electric grid in the city. Lastly,the third loop is connecting the electric grid to the electric bikes charging points that

Inspired by these 2 projects - further research is conducted to design a platform which resembles a tree structure. The branches will carry a viewing platform for patients and the leaves will be used as electricity producer.

Glass Structure Detailing Rendering
As part of Facade course in MSc Building Technology TU Delft 2017 Supervisor // James O’Callaghan from Eckersley O’Callaghan Software
// Sketchup, Vray, AutoCAD
This project is focusing on designing the connections of all-glass structure with emphasis on transparency. A new historical excavation site was discovered in the central area of Delft hence establishing new point of tourism in the city center. The whole concept is to make the observation platforms to be transparent to allow for maximum visibility of the excavation. Moreover, the observation deck is emphasizing transparency to prevent disruption of the classical skyscape of Delft. Subsequently to the appearance, the circulation is designed in such way to allow the visitors to go underground to observe the excavation closely and also walk on top of the excavation on a transparent roof. The circulation on top is necessary for reconnecting the broken pedestrian link due to the hole caused by the excavation.

05 // THE BELT high rise project in Den Haag, NL // 2016 High-Rise Building Concept Design Multi-discipline
As part of MEGA course in MSc Building Technology TU Delft 2017 Supervisor // Ir. Michiel Riedijk Software // Revit, AutoCAD, Grasshopper Role // Architect The aim of the project is to create a mixed use high rise building in front of Den Haag Centraal Station. The building has to accommodate apartments, hotels, public spaces, and Dutch parliament. The team consists different roles, from architects, structural engineer, climate designer, management, facade designer, and computational design.
43
44 The design development is executed using models and sketches. After few developments, the silver lining of each design alternative became clearer : creating non-intrusive public space for the people of Den Haag. Therefore, every design is aiming to create as much as opening in the bottom - since the existing use is as main circulation path for visitor of the main station.
45
46
The transformation shows that the parliament part is lifted to create an opening on the ground level. The parliament part is connecting housing and hotel, therefore it is called “The Belt�.
The main structure system is made from 4 concrete cores and mega trusses.
47
48
Terracota facade is applied to signify the brick tone of The Hague. On the other hand, transparent facade is applied to the Belt to emphasize the contrast.

Responsible from the initial design concept, presentation to client, to construction supervision. The main design concept revolved on the presence of light courtyard on top of reflective pool. Due to the lack of greenery in the site, water and vegetation are heavily incorporated in the interior part. All the working spaces have maximum view to the courtyard, exposing the worker to constant nature-like environment. On the other hand, the view outside is covered by the layer of perforated aluminium cladding to reduce the heat stroke.
