Ghana - Energy Efficiency in buildings
TA provider: Econoler
The Energy Commission of Ghana requested the African Climate Technology Centre support to improve energy efficiency in commercial and public buildings in the country. This is against the backdrop that Ghana has been ushered into the community of middle-income countries and a steady growth in the national economy over the years has led to increases in commercial sector activities. The number of high-rise office buildings, hospitals, hotels and super markets are therefore on the increase. Consequently the demand for electricity for air conditioning, lighting, special purpose refrigeration and operation of office equipment has increased significantly. In 2011, the commercial sector accounted for about 24% of the electricity consumed. Inefficient use of electricity in these commercial buildings and facilities would therefore exacerbate the electricity wastage and increase electricity demand.
Though the design and construction of energy efficient commercial buildings offer big opportunity for energy efficiency improvements not much has however been achieved in that area. The energy saving interventions implemented over years in the commercial sector have focused mainly on efficient lighting and air conditioning and power factor improvements. Currently, there are no regulations and standards regarding the design and construction of energy efficient buildings in the country. This poses a very serious challenge to the improvement of energy efficiency in the country in view of the rapid growth being experienced in the construction of high-rise commercial buildings.
To address the problem, it is necessary to undertake energy audits in the existing commercial buildings to establish the baseline situation which will provide the necessary inputs for the development of energy efficiency standards and regulations for commercial/public buildings.
The energy audit would cover selected public and commercial buildings with an objective of establishing the prevailing energy consumption per square meter of floor space. The data and information obtained through the energy audit will provide useful inputs into the development of the standards and regulations. The data and information will also establish the baseline situation which will make it possible to determine the impact of the project in future.
The project encompasses both research and development. The research component consists of the energy audit which will be conducted to assess sources of energy inefficiencies in public and commercial buildings, amount of energy wasted, savings that could be made when energy efficiency technologies are applied in the design and construction of these buildings, etc. The findings of this research will inform the development of standards and regulations to promote energy efficiency in public and commercial buildings. The development component of the project consists of the development of the energy efficiency standards and regulations for the public/commercial buildings. The development and enforcement of standards and regulations on energy efficiency in buildings will reduce energy consumption wastage in public/commercial buildings.
The Technical Assistance would therefore assist to undertake these two key components of the project by providing the needed resources for the following:
• Study and data gathering mainly on energy consumption profiles of public/commercial buildings, identification of sources of energy wastage, identification of opportunities for energy savings and training of energy managers.
• Stakeholder consultations and development of energy efficiency standards/regulations, public education and sensitization as well as capacity building for enforcement of the standards/regulations.
The Project seeks to improve the energy use efficiency in buildings and reduce GHG emission through energy studies, standards/regulations, public education and capacity building. The introduction and enforcement of standards/regulations will require the adoption and installation of modern and energy efficient appliances and building materials. The project therefore has the potential to ensure technology transfer into the country.
Results: Technical Assistance is being undertaken to be finalised in 2016.
