toilet flushes are 'free' out of - Nishi

Nishi—
Sustainability
at a glance
With passive design and energy effi cient
fi ttings and appliances, the need for
mechanical conditioning is virtually
eliminated and energy and water bills
are reduced to levels far below any
other apartment building in Canberra.
NatHERS
(Nationwide House Energy Rating Scheme)
rates Nishi as an average of 8 star, where the
average rating in Canberra is 2.5 star; and a
minimum new build requirement of 4 star.
Building massing & orientation
The shape and orientation of the building is
carefully designed to maximise views, daylight
and prevailing wind direction.
Solar thermal
A roof-mounted solar boosted gas fi red thermal
system provides 70% of the building’s domestic
hot water consumption on an annual basis.
Passive solar heating
Most apartments receive at least 4 hours of
sunshine per day to facilitate passive heating.
Additional mechanical heat is only necessary
during the coldest or cloudiest periods of
the winter.
Dual-aspect design
All apartments allow for cross ventilation
and daylight access.
Natural ventilation
Apartments are naturally ventilated with
operable glazing and sliding doors to provide
fresh air and free cooling during shoulder
seasons and the summer.
High thermal mass
Regulates temperatures throughout the year
by storing and releasing heat appropriately.
Thermal buffer spaces
Thermal buffer spaces in the forms of a
conservatory and terrace/winter garden
create transitional spaces between the
outside ambient conditions and the main
living space of the apartment. They limit heat
loss and infi ltration during winter months and
provide shading to the living space during
summer months.
External shading
(specifi cally designed for Taiyo apartments)
Fixed or operable shades are tuned by
orientation to reduce solar gains in summer
(minimising need for cooling) while allowing
them in winter (to minimise the need for heating).
Hydronic radiators
While passive design provides comfortable
conditions during most of the year, radiant
heating provides additional comfort during the
coldest months of the year, with lower energy
consumption compared to forced air or electric
resistance heating.
Energy-effi cient lighting
A combination of energy-effi cient lighting
will be available.
Sustainable material selection
Materials have been carefully selected based
on its minimal ecological impact. These include
low volatile organic compound (VOC) emitting
materials, renewable timber sources from
managed forests and natural materials
which can be recycled or reused.
Rainwater collection
Estimated water savings for the residential
building by harvesting rainwater will be 650,000
litres/year with an estimated 80% (4 out of 5 toilet
fl ushes are free) of fl ush water requirements
provided from the rainwater harvesting system.
Highest rated water effi cient appliances*
Based on WELS rating
(Water Effi ciency Labelling Scheme):
—6 star basin mixers*
—3 star shower heads (7.5 litres/minute)*
— 4 star toilet suite pan
(3 litre or 4.5 litre fl ushes)*
Highest rated, energy effi cient European
appliances including a 6 star dryer
* Highest rated available at time
of specifi cation.
