winning streak
From day one, pollution was cut on the PNU site. An erosion and
sedimentation control plan was implemented during construction
to reduce pollution by controlling soil erosion, waterway
sedimentation and airborne dust.
To reduce heat, the team searched for special screens and glass.
Advanced glass fiber reinforced concrete screens shade the
buildings from direct sunlight. The mass of these screens was
carefully measured to absorb heat before it reached glass.
The screens also reduced building energy consumption by
3.5% (13% reduction in heat gain on the exterior envelope). In
addition, the team chose a special glass with high insulation
properties in order to minimize the heat gain.
Buildings, streets and parking lots in the PNU colleges are
made from low-reflecting material. The material's heat-
absorbing qualities result in temperature increases in the
atmosphere above.
A potential disadvantage of big built-up areas is the heat island
effect. PNU's design counters this warming effect through highly
reflective membrane roofs. Low-reflecting paving materials
and abundant trees also combat solar absorption.
A 13-km monorail winds its way across the campus. Granting
students speedy access to most of the university's zones,
it reduces the need for many vehicles inside the campus
while providing a low-emission and fuel-efficient alternative.
Water
How water gets used (and reused) is a crucial part of sustainable
LEED design. With foresight, it is possible to significantly reduce
water consumption for general buildings and reuse the water
completely in some cases for irrigation.
A look at PNU's sustainable features
With 2.8 million m
2
of built-up area, PNU is one of the ten largest
universities in the world and the largest university for women in
the world. All in all, three distinct colleges within PNU received
LEED Gold certification:
College of Education
Composed of two buildings, the College of Education is designed
for 8,400 students. Each building covers 48,200 m
2
, distributed
over five floors.
College of Languages and Translation
A linguistic college, designed for 1,300 students occupies an area
of 37,310 m
2
, distributed over four floors.
College of Business and Management
The College of Business and Management with a capacity of
4,200 students, occupies an area of 48,000 m
2
, distributed
over four floors.
Site
An excellent starting point for sustainable design is the
site. Experts meticulously consider how it affects its direct
surroundings and seek to minimize its impact beginning with
design and carrying over into construction.
Situational thinking helped PNU become a model sustainable
campus. Buildings were positioned to use the north-south
orientation to their advantage. The positioning made the most
of breezes and cast more shade on outside student areas.
Height was also turned into an advantage: buildings were
designed to shade each other in peak hours.
