A municipal swimming pool in Sertã,
Portugal
The Municipality of Sertã is located in central Portugal
and an approximate area of 446.6 km² with a population
of 16,721 inhabitants.
Sertã Municipal Swimming Pool opened to the public on
September 29, 2009, and offers an assortment of
sporting activities in the Sertã County. It aims to promote
a healthy lifestyle, thus improving the quality of life of the
local inhabitants.
The swimming pool sports area has a workout gym, a
25m x 12.5m semi‐Olympic pool with 6 lanes (500m 3 )
and a 12.5 m x 8 m pool (100m 3 ) for beginners. Both
pools are heated to 27°C.
A decision was taken to supplement the pools
requirement for sanitary hot water and pool heating from
roof mounted solar thermal collectors.
Software modelling indicated that the required collector
area for sanitary hot water heating would be 61.38 m 2
producing an annual energy output of 41,673 kWh.
Based on the pool sizes, a pool heating collector area
was estimated to be 146.52 m 2 , producing an annual
energy output of 119,629 kWh.
This translated to105 panels each of area 1.98m 2 .
For reasons of maximising annual efficiency and
aesthetics this was reduced 96 panels installed.
The installation predicted annual CO2 emissions saving
was approximately 38 tonnes.
The value of the contract was €140,403.98 + VAT.

The sanitary hot water requirement was based on a
consumption of 4000 litres per day (100 users each
requiring 40 litres).
