This document summarizes a mix-use building project located in Ponsonby, Auckland. The main design strategy is to create a sustainable building with high energy efficiency. Key aspects include: - Commercial and residential uses with office, archive/exhibition, and residential areas - Double skin facades and PV panels to passively heat and provide electricity - Structural system uses pre-stressed TVT beams, Cross-Laminated Timber, and a steel frame - Passive design aims to balance temperatures between areas and seasons through natural ventilation and solar gain/shading

6. Office area
Main features, sustainable strategy and conceptual
usage
Double skin facade: act as an insulation layer of the building, allow air (hot/cool)
flow in-between, ideally act as a greenhouse in-between layer and produce and
transport heat to the whole building in winter
T.V.T beam: high transparency, modularity, non-brittle collapse, ductility
P.V panel: provide part of the electric to the building
Material and purpose proposal
Laminated glass (exterior glass layer): higher sound insulation rating than other
glass, safety glass that holds together when shattered, providing heat to the
“greenhouse” layer
Low-emissivity glass (interior glass layer): reflect radiant infrared energy,
encouraging radiant heat to remain on the same side of the glass, preventing
overheating the building
Pre-stress T.V.T beam: high transparency, modularity, non-brittle collapse,
ductility
Office slab (synthetic resin flooring, pre-stress T.V.T beam and synthetic resin
ceiling): light weight, strong
P.V panel: provide part of the electric to the building

(hot/cool) flow in-between, ideally act as a heat transfer portal between office
area and residential area

14. In terms of how the system works, the building is like a massive sustainable machine to balancing the internal temperature in different seasons.
In the summer day time, the window form the top north side which have a highest temperature and low south side lowest temperature is open. It can create a
solar chimney effect and bring the fresh air into the building and cooling down the interior.
At night, the building can be cooled down by using the prevailing south-western wind to exhaust the hot air to the outside.
In the in the winter day tome, the double skin layer of the building can act as a green house, providing heat from the sun and using it to heat up the commercial
building. The double bubble skin acts as a heat-transport portal, transfers the heat to the apartment on the back. Some of the heats can be instore to the floor and
release it at night. Solar cell and central heat pump also are installed in the building to provide a backup plan to the passive system.

year 3 semester 2
Group Member: Bill Ko, Derek Deng, Geoff Chen, Kyung Ho Min, Phillip Cha
Site location: 518-598 West 18th Street, New York City, New York, United States of America.
Design idea: the Highrise project is to design a building that incorporates passive energy generation to
improve the quality of life within and around the structure.
Design strategy: building merges retail business and living into one infrastructure. By utilizing this
strategy, we are able to save a large amount of real estate that is becoming sparser in this dense urban
jungle.

35. [translucent auditorium]
year 1 semester 2
Site location: 110-114 Anzac Avenue, Auckland, New Zealand.
Design idea: Using different layers of translucent glass tube to manipulate the natural light into the
building to create an atmospheric and dynamic indoor experience for its occupants.
Design strategy: Atmosphere is the main feature throughout the whole building. The roof upon the main
auditorium hall is made of various size and height of half-transparent glass tubes. The overlapping of the
glass tubes can manipulate the natural light into the hall, creating a complex yet peaceful light quality. The
special shape of the main hall and the uneven surface can have a good control with the reverberation time
and reflection sound. It will somehow enhance the volume of the performance but prevent any echos or
other unnecessary noise into audience’s ears.

36. Photo was taken from the so-call “bush” next to the site where we were having the design task on.
Even though the site is located between two nosy main streets, Anzac Avenue and Beach Road, this
little “bush” can provide people a little escape from the busy city life. Sunlight penetrates through
the gap, along with the partly sound insulation quality the “bush” and the site have, so that to create
a relax atmosphere.
As the site is close to Auckland University city campus, along with the personality the site has, an
auditorium as an extra university entertainment facility to this “exotic” land will be a humble choice.
