Sunspace augmented positive Input ventilation of buildings.

Currie, John

Abstract

A total of 16 positive input ventilation (PIV) units were installed in a new build housing
development in west Scotland utilising a glazed sunspace on the south elevation of each dwelling
to augment the energy saving potential of the installation. Data logging equipment was installed
in each dwelling to enable assessment of the energy benefit to the property derived from the
delivered air temperature, outside air temperature, delivery flowrate and occupant control setting.
Additionally, an attempt was made to evaluate the system benefits relative to occupant comfort
utilising monitoring equipment in the occupied zone of the dwellings with a questionnaire survey
undertaken in support of this. Data collected over a 16 month period showed that using the
sunspace in this configuration can save up to 15 % of the domestic heating requirements when
compared with traditional infiltration ventilation, and more than doubled the energy benefit of
that obtained by positive input only ventilation.
