rever s e m o r pho g en e s i s rethinking urban constitutive roles l o c a t i o n : t aipa , ma c a u t u t o r : ma n f r e do ma n fr e din i

the purpose of this urban park is to reinvigorate the relationship between new and old macau. this is done by using a combination of the well defined and gridded morphologies of the new high density buildings with the arbitrary and informal morphologies of the old taipa village. this urban park structure is the ‘bridge’ between the old and the new of macau and is the result of ‘excavating’ the surrounding infrastructure and remerging them into this single structure. this creates a park that is new and radical while still keeping the historic values of its site.

tu darmstadt - submerged the underground campus l o cati o n: darmstadt, g ermany tuto r: manfredo manfredi ni

the proposal for ‘submerged’ was to extend the university of darmstadt underground. this was done by employing a mat building stratergy. by using a mat building stratergy, the university campus would be easy to navigate and would use space efficiently. and by submerging the mat building underground, the university retains its original aesthetic while still increasng the number of working facilities.

urban scheme of project

claim 3 - mat buildings are inherently energy conserving - larger surface area means that the building heats quick. By being underground, the building can also draw on the surrounding soil to keep the structure at a comfortable temperature.

claim 1 - mat building allow for greater adaptability in the use of space - spaces are simple shapes, very adaptable.

claim 4 - mat buildings reduce the overall need for transportation. By having a set circulation system throughout the structure, there is no need for other forms of transport.

claim 2 - mat buildings use land more efficiently - by submerging the mat building underground, land is used even more efficiently.

claim 5 - mat buildings create their own microclimates. By having these glace surfaces at ground level, glass houses have been created.

These glass houses create their own microclimates in which would be warmer than the outside climates.

here now - reimagining new lynn l o cati o n: new l ynn, auck l and tuto rs: chri s ho l mes and anna to ng p a r t i c i p a nt of t he a uc k l a nd he r i t a ge fe s t i v a l 2013 as a me mb e r of t he ‘no s m ok i ng’ t e a m .

Live. Laugh. Unite.

Our main idea is the interaction between the visitors of New Lynn, to develop the suburb into a destination rather than a thoroughfare.

The interaction in creating the smoke rings allows people to stop and enjoy the environment, bringing in the locals and visitors together.

From previous historical transitions we are able to see New Lynn encountering a cycle of the crossovers between the horizontal and the vertical relating to the permanence.

Maori travelling across – horizontal.

The industrialisation of brick factories – vertical.

Introduction of the railway – horizontal.

Reintroducing urbanisation through the construction of apartments – vertical.

There is a a translation between becoming a thoroughfare and a destination, however there is still uncertainty in this cyclic pattern, thus the atmosphere of smoke representing the unforeseen. Ambiguity may not be a negative act, thus celebrating the unforeseen future. The best moments are brought out when there is true interaction between the people in generating more of these smoke rings. It is evident that it brings the community together, people of different ages, backgrounds and the multicultural. Funny as it may sound, No Smoking becomes a social statement that is just ironic. Where we live in a society that discourages smoking, the No Smoking installation gives an opportunity for people to interact with smoke in relation to the overall wittiness essence of the project.

retrofit of architecture building l o cati o n: darmstadt, g ermany tuto r: al essandro mel i s g ro up members: wi ng fung chan, j i so o j ung , ci nd y zhang the technical university of darmstadt’s architectural building, built in the early 1900’s had no consideration for sustainability. it is a building that is cold during winter and too hot during summer. this is a proposal for a sustainable retrofit for the campus building.

Solar Atrium Vents at the top of the atrium are opened to let stale, warm air out.

The stack effect is enhanced by the heating of black heat absorbing

Rainwater Collection Rainwater is collected and used for watering the plants inside the greenhouse and other systems such as toilets.

Photovoltaics Solar energy is collected and used throughout the building. Excess energy is fed back into the campus.

Large South Facing Vertical Greenhouse The greenhouse acts as a double facade, drawing fresh air in and dehumidifying it before passing it into the building. Warm, exhaust air is drawn out of the interior spaces and passed out through the vent at the top.

NORTH Geothermal Drilling System This system uses the consistent ground water temperature to draw hot air out and passes cool air into the building. Ducts with inlets and outlets throughout the building help facilitate this.

Photovoltaics Solar energy is collected and used throughout the building and for operating the heat pump in the geothermal system.

Excess energy is fed back into the campus.

Solar Atrium Vents at the top of the atrium are closed so warm air is trapped inside the building.

Large South Facing Vertical Greenhouse Openings in the greenhouse are closed in winter. Air inside the greenhouse is heated by the solar energy and is trapped within the cavity. This reduces the conductive, convective and radiant heat loss of interior spaces. Plants inside the greenhouse

Computerised Top Hung Window Allows natural ventilation during summer while avoiding wind-driven ventilation as the building only requires natural air passing through. These windows are closed in winter in order to trap the warm air inside, providing insulation for the building.

Manual Operatable Interior Windows Allows users to determine airflow during summer with flexibility in relation to other spaces. These can also be opened during nighttime in summer to cool the building down for the next day.

MITIGATION OF URBAN HEAT ISLAND EFFECT

LESSENING OF THE ‘URBAN HEAT ISLAND EFFECT. COMPARED TO CONVENTIONAL ROOFS WITH HARD REFLECTIVE SURFACES THAT ABSORB SOLAR RADIATION AND RE-RADIATE IT AS HEAT, GREEN ROOFS OFFER THE BENEFITS OF EVAPORATIVE COOLING, LOWER HEAT ABSORBANCE AND REDUCED REFLECTANCE.

EVAPORATIVE COOLING

A SIGNIFICANT REDUCTION IN HEATING AND PARTICULARLY COOLING NEEDS DUE TO THE INSULATION PROVIDED BY THE ROOF THEREBY DIMINISHING HVAC REQUIREMENTS. A GREEN ROOF MODERATES HEAT FLOW THROUGH SHADING, THERMAL MASS INERTIA, INSULATION AND EVAPORATION.

STORMWATER RETENTION + RAINWATER COLLECTION

STORMWATER RUN-OFF CAN BE GREATLY REDUCED AND AT PEAK FLOW PERIODS THE ROOF ACTS LIKE A SPONGE DELAYING RUNOFF AND THEREBY DECREASING STRESS ON THE STORMWATER SYSTEM. AS THE ISSUE IS DEALT WITH AT THE SOURCE THE NEED FOR STORMWATER RETENTION ‘DOWNSTREAM’ IS REDUCED.

A ROUNDED HILL GEOMETRY IS USED TO FUNNEL WIND TOWARD THE TURBINE AS SHARP EDGES CREATE TURBULENCE, AS ILLUSTRATED ABOVE. THE AIRFLOW AT THE MAXIMUM POINT CAN INCREASE THE AVERAGE WIND SPEED IN THE AREA, BUT BEING CLOSE TO A CLIFF-LIKE EDGE MAY CAUSE TURBULENCE. THIS EXAMPLE REQUIRES A 20M HIGH TOWER TO GET ABOVE TURBULENT AIR.
