General Hospital of Niger – Niger
The inpatient building is designed into a two-story courtyard space, connecting
by continuous ramps and cloisters. In addition, it can meet the hospital
accessibility requirements without lifts and elevators.
The Medical Technology Building consists of four floors, including all important
medical equipment and operating rooms in the hospital. The external wall adopts
the single small-opening windows and the external sunshade in order to reduce
the heat exchange.
Insulation is the simple and
effective way to reduce the indoor
temperature. All the roofs are
designed with thermal insulating
layers, which are prefabricated
concrete panels, to reduce the heat
transmission.
In the hot and dry environment,
building shading has significant
influence on the indoor temperature.
In order to avoid direct sunlight,
a number of external sun-shade
components are designed. The gaps
between the shading panels and
the walls form air microcirculation
around the windows, which
is conducive to carry off the
surrounding heat. The architectural
technology of this sunshade system
has high durability with in-situ
concreting.
Buildings are mostly designed with
the opened veranda of two sides’
entrances, forming good natural
convection and improving the
physical experience of people inside.
Precipitation is quite low throughout
the year. However, the heavy
rainfall is intense with strong winds,
the leaves and dust blown by strong
wind could plug the drain normally.
Open-designed drainage is easy to
clean and meanwhile presents an
important facade element. The local
loose sandy soil is conducive to the
natural infiltration of rain as well.
