Energy monitoring vision

Public sector entities are obligated by national energy law to obtain data about energy consumption and costs once per year and to establish energy management system. We would need similar management system for public lighting and public transport. Energy consumption for transport presents appx. 1/3 of final national energy consumption which is the reason to involve transport in energy management system. For public transport monitoring data about fuel consumption per vehicle in public transport is needed. Till now only data about number of km/vehicle was recorded. Public transport energy monitoring should later be implemented in private sector.

According to Decree on limit values due to light pollution of environment energy consumption for public lighting at municipal level should not exceed 44,5 kWh/person/year. To meet the requirements of the Decree monitoring for public lighting is needed. Further it would be also good to have: data about buildings envelope and other buildings data (year of construction, cultural heritage, volume, floor area etc.), standardised electronic bills for easier data acquisition, standardised bills for some fuels (heating oil, wood chips etc.), water consumption and trash. Because some bills also contain other data and thus costs between buildings or municipalities are not comparable.


Available data

Short explanation of the tables:

  • How is the data organized: It could be aggregated, detailed with specific locations, individually recorded per different units, spatial data like maps etc.
  • Who is the data provider: the entity or a person that provides the specific data (municipality, departments, agencies, businesses, individuals etc.)
  • How frequently is new data made available: regularly, periodically and how often, or on request.
  • Access restrictions: is the dataset free, open and available to public or are there any licences needed to use the data.
  • Data access point: URL of the data or contact person who is responsible for access to the resource.

Missing data

Buildings

Nature of data Volume of buildings
Why is it missing? Because there is mostly no 3d models of the buildings


Nature of data Building’s envelope structure (roof construction, walls construction, windows etc)
Why is it missing? For buildings with energy cards energy efficiency can be obtained but not envelope structure. For buildings without energy card there is no data


Nature of data Other data for simulations of energy efficiency of buildings (indoor temperature, regulation, occupancy schedule of the building etc)
Why is it missing? because it is hard to collect and is changing chaotically


Public Lighting

Nature of data Xml invoices are not standardised, but data is mostly available
Why is it missing? Xml Invoices would be better because it is way easier to collect data from xml docs compered to for example pdf docs. Some data is missing because there is no fine for companies that doesn’t include all the necessary data. The standardised form of xml invoices was generated in general (for all invoices – for example telecommunication, insurance, energy…) and because of that are not well defined for particular field.


Public Transport

Nature of data Measured fuel consumption (how many litres of fuels have been filled in gas station)
Why is it missing? For public transport monitoring data about fuel consumption per vehicle in public transport is needed. Till now only data about number of km/vehicle was recorded. Public transport energy monitoring should later be implemented in private sector.


Required ICT tools

Public Lighting

For public lighting data we would need (and we are already developing) the program to parse xml. bills and extract the useful data. Further we would need to find a way (it is possible to do it manually but it takes time) to get the data from different cadastres of public lighting and implement the useful data into our software.

  • Cadastre of street lighting should be updated in some municipalities
  • We will need to finish software to parse different kinds of xml. Documents

Software for some municipalities is already developed.


Public Transport

Software tool for public transport energy monitoring (data regarding energy consumption in transport sector at yearly level). We have identified the need to upgrade the existing tool that we already use for data collection of energy consumption in public buildings also for transport sector. The data collection of transport sector is still under developed and several data is missing. Through the tool development we will be able to collect the data about the fuel consumption/vehicle, number of km/vehicles recorded within single municipality. On a basis of collected data we will be able to elaborate economical, energetical and environmental indicators. This remote web tool will be accessible to final users (public transport performers) and will facilitate also the implementation of strategies at municipal level (SECAPs, local energy concept elaboration). The users of this tool will be trained how to handle the software and how to insert the needed data.
