The Green Campus Challenge aimed to promote energy efficiency in university campuses in Portugal. Teams of students and faculty conducted energy audits of buildings on their campuses and developed efficiency plans. The 12 finalist projects identified annual electricity savings of nearly 2 million kWh and over 400,000 euros, reducing CO2 emissions by over 920 tons. The initiative helped raise awareness of opportunities in public buildings and contributed to debates around supporting energy efficiency in higher education.

2. Green Campus Challenge – context
 The EU’s 2020 goals established a 20% improvement on energy efficiency;
 The European Commission acknowledges that one of the greatest energy saving
potentials lies in buildings where it is possible to achieve reductions up to 50%
(EU, 2011);
 Public administrations in EU Member States can save between 20% to 30% of their energy
use (heat and electricity) by 2020 (ADENE, 2008);
 The Portuguese Action Plan for the Energy Efficiency also states the importance of the
public building sector to increase the energy efficiency investments, contributing to
the target of a 10% energy reduction (PNAEE, 2008 ).
 Universities, as places of innovation and creativity have therefore a special role, along
with technical schools and industry, in the task of creating “green practitioners”.

3. Green Campus Challenge
 The Green Campus Challenge (GCC) - Energy Efficiency in Higher
Education aims to promote energy efficiency in university
campuses;
 The Green Campus Challenge was launched in March 2011. It is
funded by ERSE trough PPEEC and it is a collaboration of IST/MIT
Portugal, INTELI and SelfEnergy;
 The GCC initiative targeted the overall Portuguese higher education
network, consisting of 316 institutions and which in 2010/2011
accounted for approximately 391.000 students and 25.000 faculty
staff (DGES-MCTES, 2012);
 The main goal is to develop multidisciplinary teams to conduct an
energy audit to a specific building of a university campus and to
prepare an energy efficiency report for that building.

4. Green Campus Challenge
 The teams were asked to be formed by 50% of students, particularly by people
from different areas of study and institutions; faculty members and technical staff
could also compose the team.
 The best 3 projects receive monetary prizes, as well as the best technical and
behavioural measures;
 Industry is present in the organization of the challenge and in the composition of
the jury:

12. Conclusions and further work from the
Green Campus Challenge
 There is a real interest both from industry and academia to look at the energy
efficiency in public buildings;
 This initiative contributed to the debate around the need of creating a
coherent and sustainable business model to support the energy efficiency
benefits in the higher education;
 Another aspect that may further boost the overall interest in energy efficiency
in campus is the creation of an EU wide approach to the energy efficiency in
the higher education sector, and efforts are being made to create a EU Green
Campus Project.
