Big data för effektivare energianvändning

Big data for greater energy efficiency

Webinarium 20 April 2017 15:00 - 16:00 under ledning av professor Kornelis Blok

Data streams relevant for energy use in buildings are increasing. Many households have “smart” meters in place or are installing smart thermostats or smart plugs; and the first IoT applications are entering households. We see similar developments in commercial buildings.
This wealth of data provides new opportunities to better understand and control energy use in buildings. Significant energy saving potentials are claimed. Nevertheless, there are also serious challenges, like privacy and cybersecurity issues, and the variety of platforms.
In this webinar an overview will be given of the main developments in this new field. The challenge is how big data can empower users of homes and office buildings to create a comfortable and efficient living and working place.

Key messages
• Big data is not about data, nor is it about information technology. A big data project is about change management.
• Before starting on a big data project, it is important to ask ‘what problem you are trying to solve’.
• Key elements are good metering strategies, a plan to collect and organise data, but most importantly, a vision how to take action based on data.
• Privacy concerns need to be addressed through a regulatory framework clearly defining data ownership and uses.


Prof. Kornelis Blok
Kornelis Blok (1956) is professor of Energy Systems Analysis. He studied experimental physics at Utrecht University and received a Ph.D. degree in 1991 on a thesis ‘On the Reduction of Carbon Dioxide Emissions’. In 1984 he was one of the founders of Ecofys, where he is now Director of Science, next to his position at Delft University of Technology.



Klandra inte spegeln om Du inte gillar bilden

Då och då kommer det kraftig kritik mot de energiscenarier som till exempel IEA publicerar i sina årliga skrifter. Som senast den här från en organisation som heter Institute for Energy Economics and Financial Analysis (IEEFA) och har skrivit en rapport med det klatschiga namnet “Off Track”.

The International Energy Agency has wrongly guided governments into decisions about oil, gas and coal use that are inconsistent with the long-term climate objectives of the Paris Agreement

Men är det sant? Är det IEA som vilseleder? Så här förklarar IEA hur scenarierna konstrueras (jämför med bild nedan)

- New Policies Scenario of the World Energy Outlook broadly serves as the IEA baseline scenario. It takes account of broad policy commitments and plans that have been announced by countries, including national pledges to reduce greenhouse-gas emissions and plans to phase out fossil-energy subsidies, even if the measures to implement these commitments have yet to be identified or announced.

- Current Policies Scenario assumes no changes in policies from the mid-point of the year of publication (previously called the Reference Scenario).

- 450 Scenario sets out an energy pathway consistent with the goal of limiting the global increase in temperature to 2°C by limiting concentration of greenhouse gases in the atmosphere to around 450 parts per million of CO2.

Två av de scenarier som presenteras är alltså reflexioner av vad som händer i världen och det som är på väg att hända till följd av de beslut som fattats i olika beslutsorgan (länder, samarbetsorganisationer mm). Det är bilder INTE rekommendationer!

Om vi inte gillar det vi ser måste vi kanske rätta till de egna anletsdragen. Men klandra inte spegeln!
