Context of today’s webinar
Innovative, integrated refurbishment
packages, supported by user-centered
business models, taking into account the
whole value chain of renovation
40 to 45% of Europe’s energy
consumption comes from buildings…
further 5-10% required for the
manufacturing and transport of
construction products and components
Building sector = One of the key
enablers for achieving 2050 low
carbon economy goals
Most of the energy savings required to
meet Europe 2050 goals must come
from existing buildings.
Renovation rate only 1% today…it
should be at least 3%
What are the main barriers to the
renovation of the EU building stock?
How can we address the non-technical
ones?

OBJECTIVE 1 – To
develop systemic and
cost-optimal solutions
for energy retrofit
The main objective of the project is to develop
an holistic and multifunctional toolkit based on
the synergistic interaction between building
technologies and technical systems.
The solution has to decrease installation time by
at least 30% compared with normal construction
practices and to ensure payback periods lower
than 15 years.
OBJECTIVE 2 – To
develop, update and
adapt innovative
technologies for their
systemic integration
HEART toolkit will systemically integrate
different types of subcomponents - envelope
technologies, technical systems, renewable
energy sources and building energy management
systems - offering high levels of performance and
communicating with each other.
OBJECTIVE 3 – To foster
building’s smart
upgrade
The developed solutions will enable to convert
existing buildings into Smart Buildings, i.e. in
interactive buildings characterized by dynamic
and multidirectional flows of energy and
information.
The control logic will learn about the building’s
behaviour and its end-user habits and
preferences, identify and apply optimal operating
profiles, allow real-time monitoring, allow active
involvement of end-users and enable dynamic
interfacing with the grid.
Objectives (1)

www.heartproject.e
u
OBJECTIVE 4 – To support and
improve the decision-making
process
By means of an iterative simulation of various feasible solutions, HEART
selects and sizes the most effective one, providing a detailed prediction
of the achievable cost-performance-benefit ratio.
In addition to strengthening the economic and energy-related benefits
HEART can support and facilitate decision-making, reducing the choices’
processing time by at least 30% and decreasing final outcome
uncertainty of the decision-making phase.
OBJECTIVE 5 – To promote energy
efficient financing
HEART reduces energy consumption, optimizes overall performance
and, through a continuous monitoring and makes a building’s operating
transparent. This aspect translates into an effective conduct of a
retrofit intervention and a constant documentation of its performance.
HEART will develop innovative business models to support energy
efficiency financing, oriented both at private investments and at public
incentives. It can be estimated that these tools, breaking down risks
and uncertainties, will increase by 20% the attractiveness of energy
retrofit investments.
Objectives (2)

www.heartproject.e
u
The project’s geographical focus is
Central and Southern Europe,
where the moderate climate requires
building energy performance to
relate as much as to heating,
overheating and cooling.
Application context

www.heartproject.e
u
The application target are multi-
storey residential buildings of the
second half of the last century.
Within this category, the most
common types are 4-5 floors linear
condominium buildings.
Application target

The decision-making phase
The HEART cloud platform
allows the decision maker
(designer, building owner,
investor) to find the
optimal configuration
under the technical-
economic point of view
High investment
cost - high energy
performance
Low investment

www.heartproject.e
u
The operational phase
The HEART cloud platform acts as an
adaptive-predictive energy
management tool.
It also allows those who manage the
building (energy manager, owner
etc.), but also the O&M service and
the investor, to monitor the
technical and economic
performance and to detect any
anomalies in real-time.

Prefabricated solutions for deep
energy retrofit of multifamily houses
7 May 2019
Roberto Fedrizzi
roberto.fedrizzi@eurac.edu

If a building owner decides to start a complete retrofit with an high impact on the
energy savings, most of the time other measures are involved from structural to
electric and hydraulic
 Highly invasive
 Long lasting
 Complex for the installers (multidisciplinary integrative approach)
 Expensive (energy savings pay the investment over a long period)
Deep energy retrofit of residential buildings

The complexity involved in the multifunctional approach has to be moved outside
the construction site, where it can be managed by professionals trained with
standardised solutions
 Highly invasive  systems and installations onto the façade
 Long lasting  detailed audit, design and off-site manufacturing
 Complex for the installers  plug & play products
 Expensive  reduction of installation and commissioning costs
 shift of risk from owners to investors
Deep energy retrofit of residential buildings

Multifunctional façade system
Final concept:
Macropanel system
Assembled before installation
Made of an aluminium
substructure directly anchored
to the slabs (one floor height).
Keep an space between
existing façade and the
macropanel (15cms)
This space allows us to
allocate:
• Ducts
• Pipes
• Wires
• Other facilities
Elements integration:
• Polymer concrete panels
(passive cladding)
• Photovoltaic panels
• Solar thermal panels
• Insulation boardsARUP, HALFEN, EURAC

 The installation process is relatively short but the
design phase is significantly longer compared to
traditional processes. This requires well structured
coordination among the actors involved.
 Despite the use of prefabricated solutions, the
installation results complex to traditional installers.
Training is needed by manufacturers and at
national/local level to enhance installers skills.
 It is hard to justify the measures only by means of
simple payback time based on energy savings.
Property value needs to be considered, and
actions are needed to value the retrofit in the real
estate market. Financing solutions moving risk and
payback from owners to institutional investors is
also needed.

4RinEU approach: building deep renovation
based on information coming from data
Two levels of information can arise from two different diagnostic systems:
• from energy audit – current behaviour of the existing buildings
• from Building Sensible Data Handler – continuous behaviour of the
renovated buildings.

Conclusions & wrap-up

65
Conclusions
 Most of the barriers to energy renovation are non-technical
• Financing,
• Information, acceptance by building owners & decision-making process,
• Skills of contractors/ SMEs,
• …
 In order to allow the massification of renovation, successful refurbishment
packages must:
• Be developed with a systemic, integrated and user-centered approach, from
design to operation
• Be combined with training activities to build up skills
• Be implemented in a coordinated approach involving all actors
• Be supported by innovative business models and smart financing

66
Conclusions
 Innovative business models and smart financing are required to support and accelerate
the deep renovation of the EU building stock
• Move risk and financial burden from owners to institutional investors or banks
• Better account for non-energy benefits (e.g. property value) to decrease risk and payback time
 ICT tools/platforms have a key role to play to unclock the ‘Construction 4.0’ potential and
renovation in particular
• Entry point for one-stop-shop approaches (design, financing, coordination of actors)
• Monitoring and energy management to narrow down the gap in performance and make sure
expected savings are realised
 Cover the whole value chain, from planning to operation, including quality control:
customised service package with technical solutions + financing
