DESIGNING HIGH PER FOR MING FAC ADES
More importantly, it turned out that
introducing a natural ventilation strat-
egy offered far greater benefits than
improving glazing specifications. Seeing
as our long slim plan did not lend itself
to single-sided or cross ventilation, we
opted for a stack ventilation strategy.
Cutting a well in the plan in the darkest
area of the plan would create interest-
ing spatial connections between the
different floors, improve daylight and
serve our stack ventilation strategy.
From these tests we were able under-
stand that natural ventilation and thermal
mass were the crucial factors for our
design -- simply insulating over code
values offered far less benefit.
Our walls will have to be made from
dense materials and be of a considerable
thickness to contribute towards thermal
mass.

We achieved great daylight levels and low glare and
also introduced stack ventilation.
Walls
•
Analysing material options for walls (brick, concrete block, stud, precast concrete,
curtain and Exterior Insulation Finishing System) revealed that high thermal mass
options such as brick or concrete performed best in Annual Energy Consumption,
EUI and CO2 production terms.
•
A mix of both brick and concrete offered the right contrast in texture. We were able
to express our design intent and achieve high performance in energy terms.
