Smart EV charging systems for zero emission neighbourhoods

The increased use of electric vehicles calls for new and innovative solutions for the charging infrastructure. At the same time, it is desirable to improve the energy flexibility of neighbourhoods. This report presents the state-of-the-art of smart electric vehicles charging systems, with focus on Norway.

Recommendations for further developments in eTransport

This memo summarizes promising possibilities for the further development of eTransport, of which some are included in the ZEN work plan 2018-2019. Among other things, the described developments deal with technologies within the energy supply chains for electricity and heat, with the representation of end-users, and with the representation of fluctuations in the availability of local energy sources.

Thermal energy systems in ZEN

This report reviews the state-of-the-art on thermal energy systems for neighbourhoods. Its main focus is on technologies related to 4th generation district heating (4GDH), biomass combined heat and power (CHP) systems, ground source heat pumps (GSHP) and seasonal heat storage.

Neighbourhood building stock model for long-term dynamic analyses of energy demand and GHG emissions

How should sustainable neighbourhoods be designed to reduce greenhouse gas emissions towards zero? What kind of information do decision makers need to make solid future plans on the neighbourhood level?
A dynamic building stock model has been developed for energy- and GHG-emission scenario analyses of neighbourhoods. The model is generic and flexible and can be used to model any neighbourhood where building stock data is available.

Guidelines on energy system analysis and cost optimality in early design of ZEB

This report presents a set of guidelines to assist building designers in a methodological approach to the analysis of energy systems in the early design phase of zero emission buildings. The guidelines are meant to accompany the use of a ZEB supporting tool, guiding through the necessary steps to evaluate the performance and adapt the dimensioning of different systems to the case at hand.

Zero Village Bergen: Energy system analysis

Based on discussions with the ZEB partners, three possible solutions have been investigated for the energy system of Zero Village Bergen:

  1. District Heating (DH)
  2. Biomass fired Combined Heat and Power (Bio CHP)
  3. Ground Source Heat Pump (GSHP)
