Insulation

The thermal mass of the rammed earth walls, concrete floors and ceiling slabs act as heat sinks to stabilise temperatures in rooms, storing the sun's heat and warming buildings in winter and cooling during summer.

> See diagrams of heating and cooling systems

Wool insulation in ceilings insulates the roof against penetration by the sun's heat in summer and traps heat in buildings during winter.

Window shading from all direct summer sun reduces room heating and the impact of glare.

Water system

Water provides heating and cooling for the buildings through pipes laid in concrete floors
and ceilings. Water is stored in large tanks in the roofs of each building.

In winter, the water is heated in solar collectors on the building roof and spread through
the pipes to warm buildings. Gas heaters can also be used to heat the water.

solar collectors during the day ...
... and circulated through building floors
by pipes.

In summer, the system works in reverse, with piped water that is warmed during the day
being pumped to the solar collectors at night to allow heat to be dissipated and the water to
be cooled. The cooled water is then circulated through the building to cool it.

Ventilation

Ventilation improves cooling in buildings at night, through the use of automatic louvre
vents, which flushes hot air from large spaces and lowers the internal temperatures. Low
level vents are located beneath windows in each room, while high level vents are
located in large central shafts or high roofs.

> See diagrams of the heating and cooling systems

Cross ventilation is attained through air moving through openable windows and vents in
the central shafts or roofs. Air is also circulated in each room by a reversible ceiling fan,
which mixes warm air near the ceiling with lower cool air during winter. The fan reverses air
flows during summer to move warm air out of rooms to cool them.

Right: Ventilation is provided
through the large windows
and automatic shutter
system below each
window.

Thermal chimneys in office and teaching buildings and the Herbarium assist internal
cross ventilation between offices and corridors and help cool the building, as hot air rises
and exits through louvres at the top of each stack
.
