A3P004: Identification of needs and priorities
A3P004: Identification of needs and priorities
  In our project, we carried out a comprehensive exploration of strategies to achieve positive energy districts in a Swedish residential portfolio. The focus on urban energy transitions necessitates a holistic approach that integrates building retrofit, solar technology exploration, and heating supply optimisation.

Exploration of Local Solar Sources: The analysis reveals varying solar irradiance resources throughout the year, emphasizing the importance of strategic placement. Integration of combined photovoltaic and thermal panels into building envelopes demonstrates the potential to cover a significant portion of the energy demand even in Sweden.

Heating Supply Optimisation with Solar Technologies: Despite the surplus energy production from on-site solar technology, challenges arise due to temporal energy asymmetry. The introduction of heat pumps emerges as a feasible solution to balance energy gaps, utilising both rejected and free heat. Optimisation scenarios, utilising a combination of geothermal heat pumps, water source heat pumps, and PVT, showcase remarkable reductions in emissions and primary energy consumption.

Urban Form and Energy Infrastructure Design: We realised the importance of returning to urban form and energy infrastructure design to optimise future residential portfolio potential. Building layout design, influenced by zoning regulations and innovative typologies, plays a crucial role in achieving district level energy efficiency. Future challenges, including demographic shifts, e-mobility, and climate change, necessitate a more holistic approach to energy infrastructure design, addressing not only heating and electricity demands but also cooling requirements.

A3P005: Sustainable behaviour
  While our investigation primarily centres on technical optimisation within Positive Energy District (PED) development, it is essential to acknowledge the broader scope encompassing social and governance dimensions. Specifically, understanding stakeholders' willingness to embrace technical recommendations upon project completion is important. Several potential influencing factors merit exploration, including economic considerations, technical optimisation-associated embodied carbon balance, the general public's technical perceptions, and operational feasibility. Evaluating these aspects holistically not only enhances the efficacy of PED initiatives but also fosters greater acceptance and participation within the communities they serve.

  The Rymdgatan's Residential Portfolio in Sweden presents a compelling case study for its classification as a PED-related research, given its alignment with sustainable behaviours and overarching PED development principles as follows:

Inclusivity and Social Equity: The residential portfolio situated in Rymdgatan caters primarily to a low-income community. By focusing on this demographic, the project addresses critical aspects of social equity within sustainable urban development. Ensuring access to energy-efficient housing and amenities for economically disadvantaged populations not only fosters social cohesion but also mitigates energy poverty, a pressing concern in many urban contexts.

Multifamily Residential Building: The inclusion of multifamily residential buildings within the portfolio underscores a commitment to density and efficient land use, both essential components of sustainable urban design. Such developments promote resource optimisation by consolidating housing units, thereby reducing per capita energy consumption and infrastructure demands. Moreover, multifamily dwellings often facilitate community engagement and shared resource management, fostering a culture of sustainability among residents.

Low Carbon Retrofitting and Transition: The overarching initiative to transition the entire Jakobsgårdarna district. The included Rymdgatan portfolio, towards low carbon retrofitting, represents a significant example of decarbonization and climate resilience. By integrating energy-efficient technologies and renewable energy solutions into existing infrastructure, the project not only reduces carbon emissions but also serves as a blueprint for revitalising old urban environments sustainably. This holistic approach to retrofitting demonstrates a systemic commitment to environmental stewardship and long-term sustainability.

Climate Adaptation and Renewable Energy Integration: Despite Sweden's climatic challenges, including lower solar resources during winter months, the Rymdgatan project leverages its geographical context to optimize renewable energy utilization. Sweden's greater solar resource availability during summer and geothermal potentials complement the design's emphasis on seasonal energy planning, where surplus energy generated during peak periods can be stored or redistributed efficiently. By embracing climate-responsive design strategies, the project demonstrates resilience in the face of climate variability while harnessing renewable energy potential effectively.
