Renewable Energy Integration in Buildings

Detailed overview of innovation with sample startups and prominent university research


What it is

Renewable energy integration in buildings involves incorporating renewable energy sources, such as solar photovoltaic (PV), wind power, and geothermal energy, into building energy systems. This approach aims to reduce reliance on fossil fuels, lower greenhouse gas emissions, and promote sustainable building practices.

Impact on climate action

Renewable Energy Integration in Buildings under Energy-Efficient Buildings revolutionizes climate action by embedding renewable energy sources within urban landscapes. By reducing reliance on fossil fuels for heating, cooling, and electricity, this innovation mitigates carbon emissions, promotes sustainability, and accelerates the transition to a low-carbon built environment.

Underlying
Technology

  • Renewable Energy Sources: Solar PV, wind power, geothermal energy, and other renewable energy sources provide clean and sustainable electricity or heat for buildings.
  • Building Energy Management Systems (BEMS): BEMS can be used to optimize the use of renewable energy in buildings, balancing energy production with consumption and storage.
  • Energy Storage Systems (ESS): ESS, such as batteries, can store excess renewable energy for later use, ensuring a reliable and consistent power supply even when renewable energy generation is intermittent.
  • Grid Integration: Renewable energy systems in buildings can be grid-tied or off-grid. Grid-tied systems can sell excess electricity back to the grid, while off-grid systems require energy storage to provide a reliable power supply.
  • Net-Zero Energy Buildings (NZEBs): NZEBs are buildings that produce as much energy as they consume over the course of a year, typically through a combination of energy efficiency measures and on-site renewable energy generation.

Prominent Innovation themes

  • Building-Integrated Photovoltaics (BIPV): BIPV integrates solar panels into building materials, such as roof tiles and facades, generating electricity while serving as part of the building envelope.
  • Solar Thermal Systems: Solar thermal systems capture sunlight and convert it into heat, which can be used for space heating, hot water production, and even cooling through absorption chillers.
  • Geothermal Heat Pumps: Geothermal heat pumps utilize the constant temperature of the ground to provide efficient heating and cooling for buildings.
  • Wind Turbines for Buildings: Small wind turbines can be installed on rooftops or integrated into building facades to generate electricity.
  • Hybrid Renewable Energy Systems: Combining different renewable energy sources, such as solar PV and wind power, can provide a more reliable and consistent energy supply for buildings.
