The MOEEBIUS project is introducing 
a totally new approach to reducing energy 
consumption in the building sector, based 
on modelling the optimization of energy 
efficiency in buildings for urban sustainability. 
MOEEBIUS has been developing its work since 
the latter part of 2015, and the initial results 
are very promising.
The goal in the project was to elaborate 
products and services like the Integrated 
Energy Performance Optimization 
Framework, an Application for Consumers, or 
the multi-sensing NOD device that will enable 
the minimization of the aforementioned 
‘performance gap’  and promote customer 
confidence in the effectiveness of Energy 
Performance Contracting (EPC). The project 
also looked at the ability of ESCOs (Energy 
Service Companies) to guarantee results and 
mutually agree with customers on savings 
targets, thus reducing the business risks 
that have hindered the growth of the ESCO 
market, especially at the EU level.
Technically, the system as a whole appears 
quite complicated. Standing on a white box 
modelling approach of buildings, systems and 
distributed energy resources, a diverse range 
of components have been developed that take 
advantage of the energy simulation of those 
models and the real time monitoring of key 
performance indicators in pilot sites. Those 
components are combined in different ways, 
depending on the business scenario, use case 
and end-users’ needs. Selected applications are: 
Building Energy Performance Simulation tool, 
Demand Flexibility Engine, Dynamic Assessment 
Engine, Occupants’ User Interface, Predictive 
Maintenance Advisor, Retrofitting Advisor Tool, 
Facility Manager & ESCO Management Tool, or 
Decision Support System.
From the data acquisition side, the project 
has introduced innovations in a multi-sensor 
wireless device, MOEEBIUS NOD, for indoor 
monitoring and distributed data acquisition 
and management middleware.
In the last stage of the project the partners 
focused on the validation of specific solution 
components at large-scale pilot sites, located 
in Portugal, the UK and Serbia, incorporating 
diverse building typologies, heterogeneous 
energy systems and spanning diverse climatic 
conditions. These components started from 
different Technology Readiness Levels (TRL) 
and have been developed by a diverse range 
of project partners, from universities to 
technological centres and large companies.
As Dr Pablo De Agustin, representing the 
MOEEBIUS project coordinator, mentions, 
the potential of these models, algorithms, 
tools, etc. is impressive. However, there is 
still work to be done to prove that they can 
work together. One of the biggest technical 
difficulties in the project is undoubtedly 
integrating all the components within the 
MOEEBIUS framework and adapting its 
architecture to the needs and constraints of 
each business scenario and use case.
Living Labs (LL) activities played a crucial role 
in elaborating solutions tailored to the needs 
of potential end-users, and were an element 
which differentiated MOEEBIUS from ostensibly 
similar EU projects on energy efficiency. This 
is an environment for experience sharing and 
exchange towards user-driven open innovation of 
products and services. The activities carried out 
within the MOEEBIUS Living Labs were oriented 
towards widely disseminating the project 
outcomes, creating opportunities for exploitation 
and replication of the project results.
Most importantly, the Living Labs served 
as a channel for gathering feedback from 
the end-users and interested stakeholders 
throughout the whole project. This provided 
a basis to optimize all project developments, 
so as to directly address the critical needs of 
end-users, building occupants and relevant 
stakeholders involved in the operation of the 
MOEEBIUS optimization framework.
The pilot sites included a diverse range of 
building types and uses, where the contact 
people included professionals (ESCOs, 
Aggregators, Building Managers), with a solid 
knowledge of energy and technology aspects. 
Occupants of residential buildings also acted 
as contact points, as Dr De Agustin explains:
“These interactions with end-users 
convinced us that, in order to ensure 
that MOEEBIUS framework answered to 
stakeholders’ needs in each pilot site, the 
solution had to be flexible and adaptable, and 
their requirements should be understood.”
Indeed, the Living Lab community included 
both end-users of the pilot sites and external 
experts from academia and energy business 
sectors, who provided feedback during the project

lifetime through questionnaires and workshops. 
This approach helped project partners in the co-
creation process and in adapting the solution to 
each country and use case.
Moreover, the general reaction of Living 
Lab participants on the proposed solutions 
was very positive; “We really appreciate LL 
members’ attitude, both in answering online 
questionnaires and actively participating in 
the workshops,” dr Pablo De Agustin adds.
“In exchange, our intention was to propose 
useful solutions to diverse stakeholders in the 
energy market, from ESCOs and aggregators 
right through to consumers. Solutions are 
currently being evaluated in the pilot sites, and 
we can already confirm that project partners 
are considering  MOEEBIUS framework 
components as solutions that will help them 
in their decision making processes and in their 
day-to-day operations, working towards the 
goal of achieving energy savings.
These partners include a district heating 
company in Serbia, an aggregator in the UK, 
and building managers in Portugal,. On the 
other hand, consumers are already enjoying 
an informative consumption and billing mobile 
app, which is expected to raise awareness of 
energy efficiency among the general public.”
The main challenge faced by the MOEEBIUS 
project remains the energy performance gap: 
this is the deviation between the predicted 
energy performance of buildings and their actual 
performance. This ‘performance gap’ is reflected 
in the inaccuracy of business-as-usual modelling 
techniques as a method of representing the 
realistic use and operation of buildings.
A variety of factors are usually simplified 
through assumptions, not updated or even 
not included in static/passive models. These 
factors include the occupant’s behaviour, the 
complexities of the building (i.e. thermal bridges, 
infiltrations), alterations on building fabric, 
services, usage and controls during building 
life time, non-efficient control strategies, loss 
of performance due to low quality building 
practices and environmental inaccuracies (i.e. 
local weather, surrounding modelling). All 
these multiple and heterogeneous aspects are 
considered in the holistic MOEEBIUS approach.
Continuous calibration of the models is 
necessary in order to adjust the energy model 
to reality and keep them aligned over time. In 
this sense, the building energy models have 
been developed in EnergyPlus open-source 
software and standardized in order to allow 
dynamic modification of multiple parameters. 
A Building Energy Performance Simulation 
tool has been established in a server to run the 
models and update them according to inputs 
from other components, such as occupancy or 
user behavioural profiles, or weather forecasts.
On the other hand, a Dynamic Assessment 
Engine launches simulation requests, which 
results in Key Performance Indicators. These 
are compared with the real data measured at 
the building, modifying multiple calibration 
parameters and repeating the simulation 
requests until, through Bayesian models, the 
loop converges. An analogous approach has 
been implemented for the district level energy 
models, in this case based on Modelica.
The reduction of the ‘performance gap’ is also 
a real challenge for ESCO’s. As Post–Occupancy 
Evaluation studies in built and occupied buildings 
have demonstrated, the measured energy use 
can be as much as 2.5 times higher than the 
predicted energy use (more than 70 percent in 
the retail sector, 100 percent in residential, 150 
percent in offices, and over 250 percent in the 
education sector). So current predictions tend 
to be unrealistically low whilst actual energy 
performance is usually unnecessarily high.
In more detail, the ‘performance gap’ generates 
a consequent gap between payback estimates 
and techno-commercial Return-On-Investment 
calculations in ESCO projects which still use 
previous energy audits based on simplistic and 
inaccurate calculations. Due to this, ESCOs are 
not able to provide customers with appropriate 
simulations on acceptable paybacks of 2-5 years 
using low-cost interventions.
This constitutes a significant barrier to the 
development of the ESCO market, believes Ander 
Romero, coordinator of the MOEEBIUS project; 
“ESCOs are forced to add installations and 
commissioning services, project management, 
man hours, measurement and verification costs 
to hedge risk induced by prediction uncertainty 
and inaccuracy.” It makes many contracts totally 
unattractive, including in cases where the ESCO 
takes responsibility for the full implementation 
of a refurbishment project (from auditing to 
design and implementation). This introduces 
extra risks for ESCOs and significantly reduces 
their profit margins.
Hence, through significantly reducing the 
‘performance gap’, the holistic approach 
introduced in MOEEBIUS enhances the ability of 
ESCOs to guarantee attractive energy savings. 
“This will, in turn, eliminate the need for the 
addition of risk-hedging costs on-top of pure 
energy services, consequently increasing the 
payback attractiveness of energy performance 
contracts and reinforcing the confidence of 
customers regarding EPC effectiveness. This 
is crucial for the growth of the ESCO market, 
especially on the EU level,” says Ander Romero.
It’s obviously possible to indicate potential 
beneficiaries of the new solution. ESCO’s 
and DSM (Demand Side Management) 
Aggregators have been identified as main 
system stakeholders and as core business 
entities in the project. But occupants of 
buildings have their interest, too. According 
to assumptions of different innovative 
business models elaborated within the 
framework of MOEEBIUS, there are four 
innovative approaches tailored to the needs 
of the novel system users. In the business 
model suggesting a new energy management 
based on enhanced Energy Performance 
Contracts,  owners of specific buildings 
(public or commercial) could benefit from 
energy savings of up to 50 percent per side, 
which could be boosted by the incorporation 
of contextual and operational building 
parameters on optimization process.
Another efficiency business model for 
ESCO assumes that revenue per service will be 
offered by the ESCO to building managers (so 
that savings are shared). Along with the third 
proposed business model, raising occupants’ 
awareness is proposed as a tool for generating 
energy savings. Eventually, the valorisation 
of buildings through energy certification 
would serve as a revenue source for all system 
stakeholders.
In conclusion, MOEEBIUS enables the 
development of different business models 
in two areas -  ESCO and demand response. 
The project offers the possibility of providing 
users with fast, clear, easy, and always available 
insights into their own consumption and the 
cost of the energy used for heating. It enables 
users to learn, train, and make progress in 
their behaviour and demand response. It also 
enables remote monitoring of conditions in the 
apartment and control of the heating system. 
It enables ESCO firms, at the same time, to 
calculate more accurately the savings achieved 
by raising awareness and educating users about 
ways to save energy, which reduces the risk of 
poor EPC contracts and enables development 
in this area. So MOEEBIUS creates a win-win 
situation for all the stakeholders involved.
After nearly four years of international 
collaboration, the MOEEBIUS project will 
soon conclude its activities. The culmination 
will be the project’s final conference on 
28th of February 2019 in Wels, Austria, in 
the framework of World Sustainable Energy 
Days, which brings together more than 
650 delegates from over 50 countries from 
business, the research community and the 
public sector.
This international event is one of the 
largest annual conferences on sustainable 
energy in Europe. Every year it features 
policies, technologies, innovation and market 
development through a unique combination 
of conferences and interactive events.
