Currently, the 5th floor of the MacDonald Harrington building has
inoperable skylights and an HVAC system that cannot be controlled by the
occupants. Through our experiments, we can clearly show that this is
a missed opportunity for natural ventilation options that lead to high
energy savings and the minimization of environmental impacts.
We are proposing two modifications to the building, as well as roles
for the architects-in-training who occupy the 5th floor. First, we are
proposing to install windows that can open to their full capacity.
Through our experiments, having the full-opening capability of the
windows, as opposed to the current half-capability, provides an
important place for heat to escape, in addition to the skylights.
Second, we are proposing a skylight-switch control be installed. This
allows the occupants to decide, based on their thermal comfort level,
when to open the skylight, which in turn shuts off the heating or turns
on the air conditioning.
