Abstract

Lundellska skolan Skrapan is an upper secondary school located in the Ulleråaker district in
Uppsala, Sweden. The building was completed in 1986 and houses approximately 1150 students
and a staff of 148 members. Obtained by Skolfastigheter AB by the end of the year of 2016,
the company initiated a planning phase for a renovation. Together with STUNS (the foundation
for collaboration between Uppsala's universities, enterprises and society) a project aimed at
assessing which effciency measures would be best suited for implementation, considering sustainability
and affordability, was started. The main components being energy mapping, compiling
possible energy effciency measures, creating a model of and simulating the building's use of
energy, as well as suggesting an appropriately dimensioned photovoltaic system for the facility.
The feld of building integrated photovoltaic systems (BIPV) was examined to be able to present
a perspective of the possibilities other than a roof based building applied system, should
Skolfastigheter AB plan to construct a new school dining hall.
The building's total energy consumption consisted of 894 MWh in district heating and 580
MWh from use of electricity. By introducing lighting-, ventilation- and comfort cooling control
systems, as well as replacing old windows, the buildings energy consumption could be reduced
to 712 MWh, a reduction of 764 MWh/year. Which would bring the building below the requirements
the Swedish national board of housing and planning (boverket) has set as a standard
for newly constructed buildings. The scale of the photovoltaic system was based upon two parameters,
matching the building's needs while at the same time keeping the payback period
as short as possible. The optimal solution was found to be spreading the photovoltaic system
across three available south sloping roofs would, accruing a total effect of 61 kWp.
