How does the next generation of energy

efficient buildings look like?

SESAME and SESAME-S Projects

2 FFG COIN Projects (sesame-s.ftw.at)SESAME – Semantic Smart Metering, Enablers for Energy Efficiency (9’09-11’10)

- Prototype, proof of concepts, feasibility study

SESAME-S – Services for Energy Efficiency (4’11-9’12)

- setting up usable smart home hardware, a portal and repository

- organizing a test installation in real buildings: in a school (Kirchdorf, Austria) and a factory (Chernogolovka, Russia)

- developing specialized UIs and designing mobile apps for the school use case

Consortium partner network of 6 organizations

Motivation: work with real buildings, real data and real users

Technology:

Several Smart Meters

Sensors (e.g. light, temperature, humidity)

Smart plugs, for individual sockets

Multi-utility management (i.e. electricity, heating)

Shutdown services for PCs

User interfaces and apps: Web, tablet, smartphone (Android)

Installations in Real Life Smart Buildings

Data-Driven Management in the Intelligent Building

Millions of real life data triples collected in the semantic repository

Services Addressing Users @ School

Energy awareness, monitoring

Remote control - manual and programmed - e.g. scheduled activities and triggering rules

How do we get the users?

By having workshops with pupils: introduction to energy efficiency, building analysis, explaining the system and services

What are the stakeholders‘ needs?- Workshops at school with teachers, pupils,

janitors, management

How about energy awareness?- 47% of the pupils did not know who is

responsible for the energy management in their school.

- 69% would use an app to save energy on a regular basis

How to design energy awareness systems?

- Energy feedback and active shutdown of computers (power management)

Empowering Pupils to Save EnergyAcceptance and Effects

Using the power management app helped to save energy

No strong effect of devices used (tablet vs. smartphone)

Novel ways of energy saving are possible, but significant testing and development is necessary

NB: Rule based automation solution at the factory reported a similar level of energy savings

Communicating energy efficiency – application example (see www.alphaverda.com)

Users subscribe for the MobileApp with some of their information Address of their house / GEO position Type of the household Energy provider Energy tariff Energy consumption Devices they have

Benefits Hall of fame – a green point in the Green City Map Energy data in a GIS map in the Portal

Environmental data (CO2, weather ) Consumption and energy profiles

Residential data Public buildings (schools, hospitals, government… )

Getting insights based on aggregated data Which percentage of users from my geographic area use more energy than I use? Also a good service for city municipalities, governments

Receiving recommendations about tariffs / appliances Sharing energy efficiency practices (e.g. as policies)

Vision: Homes2District – Talking Buildings

Knowledge-based, distributed, service-oriented system solution to intelligently manage electric and thermal energy consumption and increase the usage and demand-oriented production of green energy on district level.

Smart Home Energy Datamarketplaces

Idea: A platform for publishing and querying energy data and establishing energy management services exchange between energy market stakeholders active in the smart building segment.

- Evaluation in terms of benefits for the marketplace ecosystem participants and enabling and simplifying creation of (new) data-intensive apps e.g. OpenFridge – monitoring app for consumption

Technology: semantic modeling, data analysis, scalable and economically viable datamarketplace infrastructures, new business models

Benefit: Energy companies, grid operators have means to assess the Smart Grid on a more granular level, and provide more M2M data services. Hardware manufacturers have the benefit in making their smart homes more intelligent. Third party developers benefit from the possibility to design Internet of Things apps, based on the open data. End users benefit from the new apps.

Conclusions

Real world as a research lab

Energy efficiency in buildings achieved- Via intelligent automation- Via effective human involvement

In the future, buildings, objects, agents will be interconnected via data (and will be even more intelligent)
