Environmental Energy Technologies Division Profile

Environmental Energy Technologies Division

The Environmental Energy Technologies Division is a research facility dedicated to making energy technologies more efficient and reducing their negative environmental impact. Read on to learn more about its research, departments and facilities.

The Environmental Energy Technologies Division is the energy dedicated section of the respected Berkeley Lab located in the United States.

The Ernest Orlando Lawrence Berkeley National Laboratory is an official Department of Energy laboratory that carries out world-leading research in various scientific disciplines, such as energy, physical sciences, biological sciences and chemical sciences.

The Environmental Energy Technologies Division is dedicated to performing high-quality research and development to improve energy-related technologies, whilst also reducing the negative impact these technologies have on the environment.

Main areas of research

Energy and energy technologies is a huge area, which is why the Division concentrates on certain key aspects of research. These are:

  1. Energy efficiency in buildings - this can include improving windows and lighting systems to decrease energy use and designing simulation tools to test a building’s energy efficiency.
  2. Indoor health and the environment - focusing on air quality, this research involves looking at indoor pollutants and related health risks, as well as how to improve ventilation systems
  3. Advance energy technologies - this is research into energy technologies, such as batteries, combustion technology and lasers.
  4. Energy issues in the United States - this area looks into energy efficient standards, programmes and energy policy in the US.
  5. International energy issues - this research focuses on global climate change and energy efficiency in different countries, especially China and India which are known for high pollution rates.

Environmental Energy Technologies Division departments

To conduct all this research, the division is made up of five separate departments: Advanced Energy Technologies Department; Building Technologies Department; Energy Analysis Department; Indoor Environment Department; Air Quality Department.

 The Advanced Energy Technologies Department - this department of the Environmental Energy Technologies Division is dedicated to researching how to better convert and store energy, how to reduce the negative environmental impacts of energy related technologies and how materials can increase energy efficiency. Employees in this department are specialised in:
  • Electrochemical Technologies
  • Physical/chemical Applications
  • Combustion Technologies
 The Building Technologies Department - this section is focused on developing materials for buildings, such as window and lighting, more energy efficient whilst also being practical and visually pleasing. It also builds software for architects and engineers through which they can design buildings geared towards being more energy efficient. This department specialises in:
  • Windows & Daylighting
  • Simulation Research
  • Lighting Systems
  • Commercial Building Systems
  • Applications Team
 The Energy Analysis Department - as the name suggests, this department studies and analyses energy use in all sectors of the economy (e.g. industrial, transport, residential, commercial) in the US and around the world. Its specialities include:
  • Building Energy Analysis
  • Energy Policy Analysis
  • Global Environment
  • Industrial Energy Analysis
  • Transportation Energy Analysis
 The Indoor Environment Department - this Environmental Energy Technologies Division department focuses on energy used for heating and air ventilation indoors. Its aim is to reduce the amount of energy used for these activities whilst also improving indoor air quality. Employees here specialise in:
  • Commercial Bldg. Thermal Distribution
  • Commercial Bldg. Ventilation
  • Health & Productivity
  • Integrated Risk Assessment
  • Pollutant Dynamics and Chemistry
  • Pollutant Exposure Modeling
  • Pollutant Sources and Emissions
  • Pollutant Transport Modeling
  • Residential Ventilation and Energy
  • Residential Thermal Distribution
  • Ventilation Standards
  • Ventilation Systems
 The Air Quality Department - this is a bit different from the other departments as it is a programme that aims to encourage interdisciplinary research. Known as the Atmospheric Processes, Effects and Analysis Programme, it brings together experts from the Environmental Energy Technologies Division, Berkeley University and the University of California to research topics related to air quality, such as emissions, climate change and atmospheric aerosols. The programme specialises in:
  • Urban and regional air quality
  • Atmospheric processes impacting global climate
  • Advanced computing


To perform its research, the Environmental Energy Technologies Division of Berkeley Lab has a range of advanced research and testing facilities. These include:

  • Duct Laboratory - used to study duct leaks and how to seal the, as well as how to measure air loss through ducts.
  • The Energy-Efficient Lighting Laboratory - used for the development of efficient lighting and test lighting systems.
  • The Geographic Information Systems Laboratory - used to study data from different regions and countries and spotting patterns.
  • The Infrared Thermography Laboratory - used to measure temperatures and heat loss in buildings materials using infrared imaging.
  • Interior Pollutant Dispersion Experimental Facility - used to test the spread of air pollution in indoor spaces, as well as to develop new technologies to detect indoor air pollutants.
  • MoWiTT: The Mobile Window Thermal Test Facility - used to test windows and wall insulation.
  • Single and Multiple Room Environmental Chambers - used to study indoor air pollution.
  • The Sky Simulator - used to test lightning in scale-model buildings.
  • Solar Heat Gain Scanner - used to characterise the optical properties of window and shading systems.
  • Thin Films Materials Lab - used to analyse materials and equipment designed to male windows and glazing more energy efficient.
