Our Work

The ECBCS mission is to develop and facilitate the integration of technologies and processes for energy efficiency and conservation into healthy, low emission, and sustainable buildings and communities, through innovation and research.

The remit of the ECBCS Programme covers every aspects of energy conservation in buildings and community systems. Significantly, community wide energy systems are taking on increasing importance in providing energy services to buildings. For all building types, there are many issues relating to design, construction and performance in practice that need to be resolved. To this end, the ECBCS Programme carries out projects in the following areas:
  • Community scale energy systems
  • Performance benchmarking
  • Integrated system design including renewable energy sources
  • Renovation and retrofit
  • Construction technologies
  • Electric lighting and daylighting
  • Energy measurement, management & auditing
  • Environmental assessment
  • Thermal simulation
  • Ventilation
  • Control of moisture in buildings

Specifically for non-residential buildings, we have carried out research to better understand how energy reduction may be achieved through improved design and operation of systems, including:

  • Low energy cooling systems
  • Fault detection and commissioning

Sometimes challenges posed by certain building types require special attention. Therefore, the ECBCS Programme has undertaken projects on the following end use sectors:

  • Educational buildings
  • Office buildings
  • Hospitals
  • Residential buildings

... for Researchers, Assessment Organisations & Manufacturers

Participation in ECBCS projects is decided by national representatives. So, please contact your national representative in the first instance. If your country is not listed, please contact either the Executive Committee Chair or the ESSU (ECBCS’ secretariat) for more information. (Please note the benefits of joining a project close to completion become limited both for you and for the other participants.)

At an individual level, the Programme allows researchers and others funded by national programmes and industry to pool their collective expertise to produce high quality project outputs. By taking part in the projects, they create and reinforce their own technical networks, the benefits of which remain long after the particular project has formally ended. This does not happen quickly, but over the course of three to five years, these networks of expertise become established as excellent international channels of communication.

Please see here for a comprehensive list of projects under way or completed by the ECBCS Programme.

... for Practitioners & Clients

Many of the outcomes of the ECBCS research projects are aimed at practitioners, such as engineers, assessors, architects, contractors as well as their clients such as government and private sector customers, developers and construction project managers.

Regular updates about our work are published in ECBCS News. For information about how our research findings are being used in your country, please contact your national representative.

... for Energy Policy Makers & National Research Programmes

ECBCS works according to an approved Strategic Plan (currently for 2007-2012), intended to align with the national research programmes of the member countries. Certain outcomes from ECBCS projects are intended to inform national energy policy makers about best practice for the technical basis of regulations and standards. Read more here.

Objective: To be the primary international information centre on research and development in the fields of air infiltration and ventilation, and thus to provide a high quality technical and information forum covering the areas of ventilation and air infiltration in the built environment with respect to efficient energy use, good indoor air quality and thermal comfort.

Responsive components Integrating Environmentally Responsive Elements in Buildings (Annex 44)

Objective: Investigate the performance of responsive building elements and their integration in new responsive building concepts, and to develop guidelines and procedures for the design of responsive building concepts, including the estimation of the environmental performance of responsive building elements.

Lighting Energy-Efficient Future Electric Lighting for Buildings (Annex 45)

Objective: Identify and to accelerate the widespread use of appropriate energy efficient high-quality lighting technologies and their integration with other building systems, making them the preferred choice of lighting designers, owners and users.

Energy refurbishment for government buildings Holistic Assessment Tool-kit on Energy Efficient Retrofit Measures for Government Buildings (EnERGo) (Annex 46)

Objective: Improve the decision making process for energy retrofitting of government non-residential buildings, e.g. office / administrative buildings, dormitories / barracks, service buildings and production and maintenance facilities. Though the focus is on government buildings, many results can be applied to similar private sector buildings. Collectively, these building types represent a substantial part of the non-residential building stock.

Commissioning Cost Effective Commissioning of Existing & Low Energy Buildings (Annex 47)

Objective: Enable the effective commissioning of existing and future buildings for improved operating performance. The commissioning techniques developed through this research will help to transition the industry from the intuitive approach that is currently employed in the operation of buildings to a more systematic operation that focuses on achieving significant energy savings.
