Firstly, the project is about collecting aerial image data for calculation of biomass potential, considering factors such as susceptible areas, vegetation species, fauna and history of forest fires. The idea is to obtain spectral data of the municipality biome and process RGB (Red, Green, and Blue colour composites) images to calculate the vegetation index. Then, they will make a sampling network in various parts of the municipality, and thus complement with concrete results the measurement of biomass through laboratory analysis. With the combination of aerial image data and laboratory analyses, a map will be created to easily assess the most appropriate locations to make the collection of biomass, as well as a database with all the values measured. They will carry out a viability study for the implementation of a biomass central and its energy efficiency, considering the quantities estimated to be available as fuel in the municipality and other close biomass providers.

The investment concept will focus on different sectors:

A. Renewable energy production measures: Renewable Energy Community (REC) development, through the installation of PV panels. Accordingly with the Portuguese applicable law, REC can rely on the DNO and energy suppliers for energy sharing and billing, therefore those technologies are not comprised in the initial project.

B. Energy Efficiency Measures

  • Illumination (substitution of current lights for LED and implementation of automatic lighting control systems)
  • Climatization and Sanitary Hot Water systems optimization (less efficient equipment replacement for heat pumps, both for hot water and space heating/cooling)
  • Insulation (roofs, external walls and windows renewal ), which leads to a decrease of heat excess in high temperatures weather and reduces the heat loss in buildings in lower temp.
  • The measures will be implemented in 2 schools, a cultural and an admin. equipment and in 2 householders (pilot). Subsequent expansion to 52 buildings is also included in the project

In Braga, the following measures would be financed:

  • Collection and processing of aerial image data for the calculation of solar energy, considering factors such as roof inclination, orientation, and sunlight blocking by other buildings.
  • Development of a solar map to evaluate and calculate the solar potential of buildings, where it is possible to carry out various investment simulations according to consumption, hourly occupation and the panel ideal location.
  • Evaluation and identification of the best buildings where a combination of solar panels and bio-roofs would be viable. This would consider the receiving solar energy,
  • the inclination of the roof and its area. Bio-roofs not only promote biodiversity and reduce the surrounding temperature, but they also increase the solar panel’s efficiency by preventing overheating.
  • Publication of the results in an intuitive and easy to access platform, allowing the constituents to easily consult their building’s Bio-Solar potential, as well as tools to test any solar investment in their homes.

The intended measures on this investment concept to be financed are the creation of a district heating network for the five municipalities in the application. This district heating shall be powered by a combined heat and power (CHP) plant.

The combined heat and power shall be a 50 MW plant that will have a co-generation ratio for electricity of 5:1 and can also self-sustain the electricity needed for the plant. Also, such a system shall be powered by the existent biomass and bio-waste from the region. Such a system will allow not only to increase efficiency in the heating systems, but also to replace old wood combustion at households that have very low efficiency.

Furthermore, such a district heating system, has the capacity, later on, to be adapted for a district heating and cooling system. This can be important for a preliminary evaluation and to understand if it would be feasible to have this improvement in the future.

The investment concept will focus on three main areas: Public Lighting, Renewable Energies and Energy Poverty.
The objective of the first is to substitute inefficient lighting with LED and incorporate a smart management system. For this to be possible, the municipalities will need to obtain the grid management, a possibility foreseen in the future legislation to be released. Having this in mind, a Smart-City approach will then be possible to develop along with electrical vehicle charging systems supported in the public lighting grid, along with other strategies for financing purposes (publicity, city internet, etc.).
The second investment area will focus on renewable energy communities supported by photovoltaic systems. This is being implemented in municipal or private buildings. The third and last investment area will focus on the needs of a specific population to tackle energy poverty, focusing on building envelop improvement and PV integration.

Based on audits and smart metering of municipal buildings, a model will be created for the characterization and integrated optimization of energy uses. This model will produce several fundable intervention proposals, whose individual implementation contributes to the global objective of carbon neutrality and energy self-sufficiency in each intervention building.

Different interventions will be considered, to be defined according to the characteristics of each building and open to any opportunities for funding that are available, such as energy efficiency and renewable production using different energy sources (solar, biomass, hydrogen, others), with possible creation of energy communities;

The project will leverage interventions that simultaneously promote a more circular economy, either through the reuse and/or use of water, or through the use of biomass resulting from forest management in the municipality (if applicable), water efficiency and/ or reuse, for example.
