Summary
The Cradle-to-Cradle Certification at Platinum level, awarded to products which perfectly embody the principles of Cradle-to-Cradle design, is perhaps one of the most esteemed standards of excellence in sustainability circles. Currently, there is no Platinum-level product which can deliver the classic postand-beam structural system. This literature review investigates the possibility of a timber beam product filling in that gap, and the potential design specifications necessary to do it. Findings suggest that the resin component of current glulam beams harm the Cradle-to-Cradle assessment rating, therefore posing a challenge to find eco-friendly alternative. Potential candidates such as lignin and casein resin are studied, along with the novel technology of welded dowel-laminated timber.

Summary
During this MSc thesis it has been carried out an extensive literature review on fire safety engineering, on timber behaviour on fire and on fire safety regulations in different countries. A preliminary design for a high rise cross laminated timber building (CLT) has been carried out in order to obtain a minimum thickness of the structural elements needed for the load bearing structure. This thickness has been verified according to prescriptive fire regulations. Furthermore, fire safety analyses have been performed to evaluate a more realistic fire behaviour of exposed timber structures. The finite element program SAFIR and the fire model OZone have been used in the advance calculations. Finally, it is shown that timber buildings should be designed according to advance fire safety approach and suggestions are given for developing a timber fire model.

Summary
A housing project comprised of 72 units is located in IJ Burg— a new suburb east from the center of Amsterdam. More specifically, the project sits on a man-made island called Steigereiland North, on a ‘left-over’ green strip of land. Two types of dwellings (A and B) are disseminated around the site forming various permeable blocks of living and working units. These apartments consist of free-standing, row, and semi-detached typologies, depending on their arrangement and orientation. The capacity of these units to grow and change over time is a key feature of this project. The project has an additional activity strip between the waterside and the housing fabric border which will aid to serve as a lively catalyst for the neighbourhood. This ‘mat’ consists of landscaping and supplementary functions such as: tennis courts, a soccer field, playgrounds, picnic zones, pergolas, a climbing wall, a dance studio, and storage facilities. The newly-added layer of economical, community-driven activities reinvigorates IJ Burg. Introducing light production as well as the creative and working classes into the urban fabric will also result in an extrovert and well-functioning community.

Summary
In this research the effect of using the combustible material CLT as the main bearing structure is investigated. As a combustible material, unprotected CLT can burn along with the fuel load present in a compartment. This master’s thesis aims to increase insight into the fire behaviour of unprotected CLT structures in a compartment burnout, conservatively assuming no active measures. The main research question of this work is: “Under what conditions is there a potential for self-extinguishment of cross-laminated timber?” A model of self-extinguishment of CLT was created which consists of various phases of a compartment burnout. Under the influence of an initial fire due to burning of room contents, the exposed CLT becomes involved in flaming combustion. Once the room contents have been largely consumed and the initial fire decays, the CLT contribution is expected to decrease as well, transforming from flaming to smouldering combustion. Finally, there will be a transition from smouldering to self-extinguishment. Two series of experiments were conducted to investigate this model and the conditions under which the transitions can take place.
