Road to the North East and Number 1 Hawthorn Avenue to the South East. The
proposed design is a three storey house equipped with a draught lobby, 2 children
bedrooms on ground floor, open kitchen-dining space with a lounge on the first floor, 1
master bedroom on the second floor, 2 bathrooms and a storage & machine room. The
designing of the house has been completed keeping in mind passive design techniques
for optimal use of solar gains. Adequate sized openings have been on desirable facades
for the purpose. In addition, there have been considerations made for the integration of
PV panels into the south-facing roof top whose sloping angle is estimated at 30
o
(Fig. 2).

Investigation of Solar Availability in Scotland
The general climatic conditions and solar irradiation levels of a potential construction site
in South Ayrshire were reviewed (Fig.3). In South Ayrshire, the daylight hours were
estimated to be 198.4 hours in the month of May and 37.8 hours in December. The
amount tends to increase from April to September and reduces towards December.
