The heating requirements of the rooms were calculated based on design specifications,
with certain exceptions. When the outdoor temperature reached -30°C, the required
room temperature varied between +10°C and +40°C. Ventilation was adjusted according
to design specifications and it was required to work at full capacity when the outdoor
temperature was between -10°C and +5°C.

Specifications of the water, sewage and heating systems. PSA.Despite the fact that the indoor temperatures and ventilation rates were
designed separately for each room by type of space, it is not clear from the specifi-
cations how these design values were to be reached. For example, the architectural
and structural designs did not take into account the heat insulation capacity of the
structures. The design values for indoor temperature and ventilation were not dealt
with in the designs in any systematic manner by analysing the combined impact of
the systems and spatial entities.
Aalto was also interested in developing a panel radiator model. He contacted Ab
Wärtsilä Oy, a shipyard and a mechanical workshop in Helsinki, in June 1931 and
suggested a completely new panel radiator model. The company showed interest and
