Paper Abstract

As a sustainable energy transition will see increased electro-mobility, its impact on the energy system needs to be understood and well integrated in planning. The Positive Energy Districts in this work consists of several buildings (new, retro-fitted or a combination of both) that actively manage their energy consumption and the energy flow between them and the wider energy system. Positive Energy Blocks/Districts make optimal use ofadvanced materials, local RES, local storage, smart energy grids, demand-response, cutting edge energy management (electricity, heating and cooling), user interaction/involvement and ICT. Positive Energy Districts are designed to be integral part of the district/city energy system and have a positive impact on it. Their design is intrinsically scalable and they are well embedded in the spatial, economic, technical, environmental and social context of the project site.

Integrated requirements for Positive Energy Districts were developed and tested in a mixed used area of Trondheim, Norway. The environmental, economic and social performance indicators were-identified Related to environmental impact the ISO 14031 Standard presents 3 categories of performance indicators: Management Performance Indicators (MPIs), Waste Indicators (WI) & Environmental Condition Indicators (ECI). For energy planning aspects the following indicators were identified:

  • Site or end energy (SE); Source or primary energy (PE); Energy Efficiency (EE); Energy Security (ES); Energy Independence (EI); Energy Resilience (ER); Reliability of Energy Systems (RS)

With these indicators the interaction and integration between the buildings, the users and the larger energy system can be monitored. The results can then be used to address implications of increased electro-mobility, its impact on the energy system and its integration in planning. Some of the main outcomes of the project are:

  • Focus on mixed use urban districts show improvements in performance indicators
  • The developed solutions are modular and can be replicated/gradually scaled up to city level..
  • Communication to local communities and local governments (particularly city planning departments) is an active and integral part of the solution, increasing energy awareness and ensure sense of ownership of smart solutions ensures sustainability of Positive Energy Blocks/Districts;
  • Promotes decarbonisation and resilience, while improving air quality.

The analysis of monitoring results led in some cases to the development of effective business models for sustainable energy services solutions; storage solutions (from short-term to seasonal); big data, data management and digitalisation solutions; and electro-mobility solutions.

Conclusions:

The objectives of climate mitigation and adaptation goals, local energy, air quality and climate targets and a secure and resilient energy system were met. Furthermore, it significantly increased share of i) renewable energies, ii) waste heat recovery and iii) appropriate storage solutions (including batteries) and their integration into the energy system and iv) reduce greenhouse gas emissions. This will lead the way towards wide scale roll out of Positive Energy Districts supported by significantly improved energy efficiency, district level optimized self-consumption, reduced curtailment. In particular the increased uptake of e-mobility solutions together with improved air quality has the potential to show the way for follow cities.
