2020 and beyond. In this respect, the European Union’s 2020 target, aims to a 20%
enhancement in EE at all stages of the energy chain: generation, transformation,
distribution and final consumption.
This subsection describes a set of procedures on the climatisation system carried out on the building TCM1 for reduction in energy consumption during this last
stage of the chain. All these applied measures are focused on heating-cooling control
system efficiency. The planned actions undertaken were designed following the recommendations laid down in the existing European Directives 2030/31/EU regarding
EE and 2010/31/EU on the Energy Performance of Buildings.
The implementation of an automatic system for the disconnection of heating/air
conditioning systems in every classroom, lab and office, has been realised. The system
easily governed by means of an electronic device installed in every dependence, turns
climate system off two hours after start-up. Moreover, a data analysis stage in order to
identify correlations between energy consumption and classroom and lab occupancy
(by using the ratio of the number of students per lecture and per lab), has been also
fuelled by the TCM-LL to be able to appropriately establish a specific correlation
between actions and quantitative results. In addition, to provide every classroom and
laboratories with a distributed network of infrared active sensors, for the required
people presence control, has been also explored. Note that this infrared technology
is also applied in the toilets of each building of the Park in order to optimize the use
of lighting resources.
Additionally, due to the energy requirements may be significantly different
depending on the local context, outdoor climatic and local conditions of the Mataró
city, have been taking into account. Thus, a set of specific actions to further improve
building energy performance, has been undertaken throughout the period considered.
The following briefly summarizes the major ones:
• Implementation of a routine of total stop of the primary circuit of heat pump during
the summer period, in order to drastically reduce the energy bill from the Tub Verd
supplier company in this period of non-academic activities.
• Installation of solar protection windows based on thermal material, following the
standard passive design methodologies (Hermelink et al. 2013; Mazria 1979) for
reducing indoor overheating, especially when dealing with glass buildings and
similar ones, such as the TCM1 building.
4 Results and Discussion
We present the annual consumption assessment for each year from 2014 to 2017. We
have considered that this period is enough to be able to establish a first trend analysis.
Consumption values have been directly extracted from energy bills. Tables 2 and 3
respectively show annual consumption from Tub Verd to cover heating and cooling
requirements and annual consumption per student. Although is broadly known that
cooling and heating requirements may vary greatly depending on weather conditions,
