Solar neighborhoods are communities prioritizing the exploitation of solar energy, with limited energy management systems. Buildings’ morphology and relations, building envelope and material features are designed to maximize the efficiency of passive and active solar strategies. Solar neighborhoods are characterized by a microclimate that enables adequate thermal and visual comfort, and high life standards, both indoors and outdoors.
 

What are the challenges?

• The current trend shows, that energy needs for space cooling – almost entirely in the form of electricity – will more than triple between 2016 and 2050, driven mainly by the residential sector (2,000 TWh => 6,000 TWh)
• Most of the projected growth in energy use for cooling is set to come from India, China and other emerging economies
• Space cooling is set to overtake appliances and plug loads to become the single largest user of electricity in buildings (2015: 10%; 2050: 30%)

Presentation at S-@ccess, International Conference on Solar Technologies and Hybrid Mini-Grids to improve energy access, Spain, April 26-28, 2023.

An enormous task:

• decarbonising around 6,000 district heating networks across Europe.
• solar heat is one of the proven, available, cost-effective measures to help complete this enormous task.

In this presentation we would like to show you how solar district heating works and who is using it successfully already

This seminar aimed to bring academic and professional knowledge, of designing sustainable communities with high life quality. In addition, it introduced and demonstrated the use of modeling tools in the design process to achieve specific performance goals, at urban and building levels.

The main objective of the Fall School was to introduce and discuss various solar strategies, and methods employed to assess and evaluate these solar strategies and concepts, from various perspectives and standpoints. Selected topics of presentations and discussions encompass:

• Status of solar technologies deployment and 100% renewables,
• Life cycle of solar technologies and impact,
• Socio/economic aspects,
• PV and solar thermal collector integration in buildings,
• Simulations of neighborhoods to analyze different solar strategies,
• Overview of various strategies and applications,
• Technologies and sustainable developments - case study from industry perspective.

This conference from mid-October, held at the European Congress on the Use, Management and Conservation of Buildings of Historical Value, featured several talks from the project’s partners and relating to Task59. Firstly, we saw two invited speaks amongst our partners: Dr Alexandra Troi of EURAC Research giving an overview of Task59, and Walter Hüttler of e7 energy innovation & engineering speaking on the role of research in the use of renewable energy in historic buildings.

Following this was a parallel session dedicated to Task59 and featuring presentations from project partners under the topics of Best Practices: Engaging Owners in Energy Renovations; Quality Assurance in Energy Retrofits: The Role of Standards and Simulation and Energy Retrofits: Tools for Better Decision Making.

Several of the project’s partners were able to attend the European Parliament in Brussels, Belgium for the Renovate Europe’s REDay 2019. This took place on Tuesday 8th October 2019. In addition to participating in round tables, presentations and discussions, several of the task’s case studies were also features as part of the REDay Exhibition, which stayed on display until the 11th October. This exhibition was a showcase of best practice renovation projects and programmes which can prove that energy renovation is not only possible, but already happening across the world. On the task’s part, we showcased Scottish renovated buildings as well as the work done in Villa Castelli, Italy, which is using 90% less energy. EURAC’s Daniel Herrera gave a presentation on the development of the ATLAS project database at the conference before the opening of the exhibition.

Mr. Herrera presented at this conference that covered the integration of solar energy in historic buildings, energy recovery, and Building Integrated Photovoltaics (BIPV) in architecture.

This is a one page overview of what Task 60 was about (2018-2020)

Mr. Herrera presented at this conference which approached and explored the technological, economic, ethical, behavioral, governance and public policy aspects of (analyzing and designing) urban energy systems. The conference was from a comprehensive engineering perspective, and aimed at highlighting current trends and issues affecting urban energy systems.

- Compact façade integrated MVHR and heat pump for decentral ventilation and heating
- Potential of onsite-PV to reduce non-renewable primary energy consumption
- Results of the project "SaLüH"

Abstract - A new building with 14 small flats is designed according to Passive House standard in Innsbruck, Austria. Heating and domestic hot water (DHW) supply are planned to be covered using direct electricity. Electric heaters are used for space heating, and electric boilers for DHW (one per flat). The whole south façade is covered with a Photovoltaic (PV) system of 27.3 kWp, aiming to cover as much as possible of the electricity needs. The idea was to keep the investments costs low, minimize the installation effort, eliminate the distribution losses, and increase the share of on-site renewable energy production using the available space in the façade [...]

Mr. Herrera and Ms. Aitziber Egusquiza, of Task 59 partner Tecnalia Research & Innovation shared their experience on Historic NZEB at the European Wise Event, organised by the Interreg Europe project VIOLET (preserVe tradItiOnal buiLdings through Energy reducTion) in Seville, Spain. Ms. Egusquiza presented the details of a methodology for decision making in the energy retrofit of historic areas and Mr. Herrera outlined the activities developed in Task 59 aimed at bridging the gap between research and practice in the renovation of historic buildings.

- Assessment of photometric properties
- Relation between photometric properties and lighting conditions in indoor spaces
- Energy performance and user acceptance studies

Keynote Presentation at EuroSun 2018 on October 12, 2018 by Daniel Herrera.  Talk: Historic buildings are trademarks of many cities but they will only survive if maintained as living spaces. Finding conservation-compatible technologies will be crucial for the built heritage and the opportunities for solar energy integration are far more substantial than one might initially expect.

Presentation given at the 83rd ExCo Meeting held in Stockholm, Sweden in June 2018.

Abstract - At the moment hardly prefabricated façade modules with integrated building services are used for the thermal renovation of residential buildings. Within the frame of the national research project “Prefabricated façade elements with maximum integrated HVAC components and systems for the renovation of existing buildings” the potential for the intelligent renovation of existing buildings should be shown and new solutions should be developed. A highest possible level of prefabrication should minimize the required renovation time and avoid vacancy. In particular, the aim is also to find solutions which allow a direct interaction of the HVAC components in the building façade with the room behind [...]
