A Holistic Approach
Finding your building's perfect energy balance.
By Gene Albano
hether your building is of
newer construction or in
need of improvements, energy
efficiency provides a great platform
to "rethink" your building and
integrate plans for all of its elements.
That's because, as every building
owner and manager in Hawaii
must be painfully aware, our island
state imports fossil fuel to produce
94 percent of our energy, and has the
highest electricity rates in the U.S.
Air conditioning, in particular, is
expensive, averaging 34 percent of
electrical usage in an office building,
but going as high as 80 percent in
some cases. Lighting ranks second,
at an average 27 percent of an office
building's energy costs.
For building designers, this
poses a very basic challenge: How to
make use of Hawaii's free, abundant
daylight without also letting in the
In the past two years, WSP Hawaii,
the local arm of an international
engineering firm that specializes
in energy efficient design and
construction, has worked with
architects and owners to come up with
two very different, cutting-edge work
spaces-'Iolani School's Sullivan Center
for Innovation and Leadership, and the
University of Hawaii Cancer Center.
Both pioneering projects were
designed to meet the stringent
standards required to receive L.E.E.D.

comfortable green buildings that foster
cooperative learning and creativity-
and are also sustainable in terms of
Similar to office buildings,
educational/research facilities face
high cooling loads. Each of these
projects faced unique challenges that
make them a constructive case study
in building green.

Sullivan Center at 'Iolani School
'Iolani School's Sullivan Center
for Innovation and Leadership (SCIL)
took shape in a creative process of
collaboration between the architects
of Group 70, the school trustees,
administration, teachers and students
and WSP Hawaii.
Perhaps the single most
distinguishing and arresting feature

center is its soaring glass curtain
wall that stands four stories high and
covers the full width of the façade.
This transparent, sky-blue building
"skin" is beautiful and highly
functional, providing abundant, nonglaring daylighting throughout SCIL.
For WSP Hawaii, the curtain
wall presented a dual engineering
challenge-preserve Group 70's
inspirational design and its sense
of freedom while maximizing the
center's energy efficiency.
WSP Hawaii could not rely on
typical external resources to help keep
the building cool, as the architects
specified no external shading because
they wanted to showcase the unique
application of the glass façade and
preserve the building's views. As
such, WSP had to strike just the right
energy balance with a combination
of high-performance window glazing
and wall and roof insulation.
Fortunately, the building's primary
east-west, south-facing orientation
minimizes the sun's heat penetration
into the building. Also, like other
structures in this sun- baked school,
SCIL features photovoltaic solar panels
on its roof that offers a sun barrier and
produces renewable energy.
