systems across buildings, airports, underground stations or optimising

energyusage with the perimeter of a district, developing energy-positive

and proactive neighbourhoods, intelligent neighbourhood energy

allocation and supervision, energy forecasting, orchestrating integrated

renewable generation in neighbourhoods, co-ordinating energy usage

and storage in buildings, balancing energy production and consumption

at neighbourhood level, and developing smart solar-powered micro-grids;

all these are examples of project sub-objectives to be reached. In

particular, these can be assisted through information and communication

technologies such as holistic information modelling and simulation, 3D

visualisation, semantics-driven design, self-learning concepts or the use

of sounds to improve energy control.

Last but not least, the addition and fully complementary nature of the

PPP EeB projects within the broader smart cities strategy is currently

being proven through several projects aiming at demonstrating

technologies that are validated at building or district scale. At the large

city level scale, their innovative potential is being displayed through

lighthouse developments.

energy use data may be displayed to educate

homeowners, employees and the public as a

means to influence their behavioural patterns.

The critical role of refurbishment

Of course, under the main target of actions, the

existing building stock has been particularly

tackled in many PPP EeB projects in order to

analyse and demonstrate how innovations can

be integrated under the numerous and various

constraints enforced by the legacy of structures

built in the 19th and 20th centuries. A key to

achieving this goal is to understand the process

of selecting and integrating various

technologies from the many available. A truly

holistic approach is required to optimise the

performance of different building types,

climates and socioeconomic solutions while

taking account of the users of the buildings.

Meanwhile, some projects have focused their

objectives on certain categories of buildings

and technologies, such as the cost-effective

integration of renewables into existing high-rise

buildings; the issue of historic buildings, which

are the trademark of so many European towns

and will only survive if maintained as living

spaces; the schools of the future; multi-storey,

multi-owner residential buildings; buildings in

the Mediterranean area; standardised façade

system modules and panels; public non-

residential buildings; and re-conceptualisation

of shopping malls. Other projects deal with the

issues of encouraging a massive market

uptake, creating an impressive replication

potential, developing systemic packages,

possibly prefabricated, or developing renovation

strategies and toolboxes.

Optimising the operation of

buildings within smart cities

Once adequately designed and constructed or

renovated, buildings need to be operated with

their energy performance monitored and

managed in the most optimal way. Numerous

projects approach the different facets of this

search for optimisation. One of the ultimate

objectives is to ensure the durable high level of

performance of the various components and

the building itself, both as a total single entity

and as a composing element within the global

system, taking account of the European energy

grid level. Providing intelligent management

Defining European action towards reduction of the energy

consumption of buildings are 2010’s Energy Performance of

Buildings Directive and 2012’s Energy Efficiency Directive. A

number of measures are pushed under the buildings directive,

including the inclusion of energy performance certificates in

advertisements for the sale or rental of buildings; inspection

schemes for heating and air conditioning systems; the obligation

for all new buildings to be nearly zero energy by 31 December

2020; the setting of minimum energy performance requirements

for new buildings, for the major renovation of buildings and for the

replacement or retrofit of building elements; and EU countries have

to draw up lists of national financial measures to improve the

energy efficiency of buildings.

Meanwhile, the Energy Efficiency Directive means that EU countries

make energy efficient renovations to at least 3% of buildings

owned and occupied by central government; EU governments

should only purchase buildings which are highly energy efficient;

and EU countries must draw-up long term national building

renovation strategies which can be included in their national energy

efficiency action plans.

With efforts continuing to foster innovation in the sector, there is

confidence that Europe is on the path towards a sustainable future

for buildings.
