CONCLUSIONS

Plan van aanpak Na de P2 kan een bouwdeel verder worden uitgewerkt. Dit houdt in: het ontwerpen op basis van bestaande methoden en voor zover nodig uittesten van nieuwe methoden. Uittesten zal gebeuren op een bouwdeel dat representatief is voor de rest van de constructie in een proefopstelling. Eventueel gebeurd dit op schaal om in het laboratorium te kunnen testen. Uiteindelijk zal het ontwerp haalbaar moeten zijn en nieuwe kennis genereren voor volgende projecten.

10.1

10.2

Afbakening Het onderhoud en energiegebruik van het gebouw wordt ook meegenomen maar is geen hoofdonderwerp. Onderdelen kunnen voordat het niveau van definitief ontwerp en bestek worden bereikt, eventueel eerst met een aannemer worden besproken. Resultaten kunnen bijvoorbeeld zijn: conclusies, tekeningen en andere documenten die benodigd zijn om een bouwaanvraag in te dienen.

The Green Material MazeHere well explore examples of how building materials are changing, from manufacturing culture and environ-mental stewardship to up cycling and closed loop products. We will look at how to choose the right recycledor recycled-content material for your projects.

Well review several different certification systems including Cradle to Cradle, Scientific Certification Systems,Green Seal, and Greenguard. Examples of how to use these products for prescriptive programs like Built Greenor LEED will also be provided.

3.10.Efficient styles

Whereas efficient climate control usedto be considered peculiar,now it has

turned into an asset ofprestige.Oneofthe early examples is the main

office building for the NMB Bank inAmsterdam by Alberts & Van Huut.It

really is a little strange,relating as itdoes directly to RudolfSteiners ideas,

with its mountain-like slanted struc-ture,elaborate brickwork and small

windows.It is one ofthose buildingsthat is loathed by most ofthe archi-

tectural community and loved by thepublic.Its climatological quality

mainly depends on insulation and water flows inside.Alberts & Van

Huut continued to refer to organicshapes,but climatic efficiency became

subject to modernist architecturalconventions about transparency.

The NMB Bank is now part ofINGGroup,an organization with a long

history ofimportant architecturecommissions.They were one ofthe

early clients ofBerlage.Recently Meyer & Van Schooten designed a

new high-tech building for their top-level executives in Amsterdam.It fea-

tures the latest in efficient climatecontrol and bears a strong resem-

blance to Future SystemsGreenBuilding.To the users inside,the steel

structure,glass,gardens and largeempty spaces provide a dynamic ex-

perience ofworkspace quality.Thelook ofthis slick modern product-

form with its aluminium panellinghas caused the building to be popular-

ly dubbed The Dustbuster.What remains is the question ofwhether

prestige and efficiency are compatible.

Results and discussion

The kenaf composite panels were successfully manufac-tured. However, the high density (0.55g/cm3) of compositepanels made by the one-step pressing method showed slightdelamination. The reason may be as follows: the boardswith high densities have high compaction ratios (i.e., 3.9for a board with a density of 0.55g/cm3), making it difficultfor the steam inside the board to escape, while, in addition,in this study, the MDI adhesive formed a film on the boardsurfaces and prevented the steam from escaping, therebyproducing high steam pressure inside the board. When theinternal pressure of the steam in the particle mat is higherthan the bonding strength of the board during unloading,delamination might occur. In this study, use of a vacuumsystem may have lightened the delamination, because itwas not observed in panels with densities of 0.45g/cm3.However, use of the vacuum system did not completelysolve the problem. No delamination was observed inthe high-density composite panels made by the two-stepoperation.

The specimens that were delaminated were notevaluated further, and thus the number of test specimensdecreased.

Bending strength

The effect of board density on the MOR of kenaf compositepanels manufactured by one-step and two-step pressingmethods is shown in Fig. 1. The MOR values of the com-posite panels from the one-step and two-step pressingoperations increased with increasing panel density. Therelationship between MOR and density of one-step com-posite panels was similar to that of the two-step compositepanels. Compared to single-layer kenaf binderless particle-board, the MOR of the composite panel was improved,especially at the low density level. At a density of 0.3g/cm3,the MOR value was 8.0MPa, 3.2 times higher than that ofthe single-layer binderless particleboard, which was only2.5MPa, whereas at a density of 0.6g/cm3, the MOR valueof the composite panel was 20.9MPa, 1.4 times that of thesingle-layer binderless particleboard. During bending test-ing, all the failures were caused by bending failure when themaximum bending moment was developed.

The increase of the MOR value of the composite panel isdue to the relatively higher strength value of the kenaf bastfiber-woven sheet when compared with kenaf core particle-board. The tensile strength and Youngs modulus of wovensheet at various densities are shown in Fig. 2. The tensilestrength of kenaf bast fiber-woven sheet increases with in-creasing density. In kenaf composite panels, the thickness ofthe kenaf bast fiber-woven sheet was around 0.5mm despiteboard density, and thus the density of the kenaf bast fiber-woven sheet was calculated to about 0.75g/cm3. The tensilestrength was 36.3MPa. The high strength of kenaf bastfiber-woven sheet serves in imparting strength to the kenafcomposite panel. Because the weight ratio of the kenaf bast

fiber-woven sheet to the core layer decreases with increas-ing density of the kenaf composite panel, the improvementin the MOR value in high-density composite panels was notso evident when compared with the low-density compositepanel.

At the densities of 0.42 and 0.54g/cm3, the MOR valuesof kenaf composite panel can meet the requirements of type13 and type 18 particleboard, respectively, according to JISA5908-2003.

As shown in Fig. 1, the MOE values of both one-step andtwo-step composite panels increased almost linearly withincreasing board density. The MOE values of one-stepcomposite panels did not show much difference with thoseof two-step composite panel. At a density of 0.3g/cm3, the
