Smart buildings of the future need comprehensive and
extendible cross-domain management and control
functionality that today’s building automation and
management systems (BAS) do not adequately provide.
These buildings should not only create an environment
that optimises the conditions in which people can
work and live in comfort and with security but should
also ensure that management and maintenance are
performed effectively and efficiently. The BaaS (Building
as a Service) project set out to tackle these challenges by
introducing a novel semantic IoT service framework for
commercial buildings along with a reference architecture
and corresponding software platform as a basis for
current and future commercial building automation and
The BaaS Reference Architecture provides common
concepts and guidance for the development of concrete
BaaS platforms. In particular, the BaaS Information Model
facilitates the semantic modelling of devices, functions and
data and thus provides a blueprint for the specification
and generation of BaaS services. The establishment
of a BaaS system follows a service lifecycle model that
covers the phases of Design, Development, Engineering,
Commissioning, Operation and Optimisation. The BaaS
platform provides a number of tools and methodologies
supporting the first phases of this lifecycle while the BaaS
runtime facilitates the capabilities needed to operate a
system of BaaS services. A technical management system
monitors the services and ensures their proper operation.
The benefits of the BaaS platform and runtime have
been shown in various application demos, including
an Emergency Evacuation demonstrator and a Smart
Workplace demonstrator. Building automation engineers
benefit from BaaS tools that facilitate easy and flexible
modelling, development, engineering and commissioning
of services while tenants benefit from enhanced comfort,
better customisation of services and energy savings
through presence detection and environment awareness.
Essentially, the BaaS approach can serve as a blueprint for
stakeholders in future BAS ecosystems and provides for
promising exploitation options.
Project leader Materna continued to develop its Open
Source JMEDS (Java Multi Edition Device Stack) framework
based on DPWS (Devices Profile for Web Services) in BaaS.
The foundations for JMEDS were laid in the ITEA projects
SIRENA and OSAmI. JMEDS implements an abstraction
layer for the integration of diverse device technologies as
used and found in BAS.
BOR Software generated a commercial product from
the BaaS results: BEY, a Building Inventory Management
tool for commissioning, operating and monitoring BAS.
After BaaS, BOR has established a new division for Smart
Environment Engineering releasing commercial products
and professional services. In 2013, BOR was not familiar
with smart environments, but now the company has a
strong business in this field. BaaS gave BOR a fast learning
curve to convert knowledge into commercial exploitation
and new opportunities.
Prodevelop provided the prototype 3D Web Visualisation
for Real-Time Maintenance of Smart Buildings in BaaS. The
company has used BAS added-value services to enhance
its POSIDONIA Space © (Smart maintenance of harbour
infrastructures) and POSIDONIA Safety © (Emergency plan
specification and execution based on outdoor and indoor
location systems) solutions.
Siemens has taken advantage of the results of the BaaS
project for supporting the development of new BACnet
standards (a data communication protocol for Building
Automation and Control networks) together with Siemens
Building Technologies. Ideas from the BaaS project
have contributed to the Technical Working Group of the
Fairhair Alliance, launched in 2015, to adopt and develop
IoT technologies for Building Automation Systems, with
Siemens, Philips and NXP as members.
