project description

In line with the implementation of Sustainable Energy for All initiatives in Africa, the Climate Technology and Finance Center and Network has accepted a request from the Energy Commission of Ghana to improve energy efficiency in commercial and public buildings in Ghana. Considering the rapid growth in the construction of high-rise commercial buildings, the design and construction of energy-efficient commercial buildings offer big opportunities for energy efficiency improvements.

The African Development Bank (AfDB) hired Econoler and its partner firm GFA with the overall goal to improve the energy use efficiency in buildings and reduce greenhouse gas emissions through energy studies, standards and regulations, public education and capacity-building. More specifically, the project objectives are summarized as follows:

  • To conduct energy audits in selected public and commercial buildings to determine their energy consumption pattern and levels
  • To use the energy consumption information obtained from the energy audit to develop energy efficiency standards and regulations for public and commercial buildings
  • Deliver a 5-day training session on energy efficiency, including energy audits

highlights

This research and development project had two key components. The first one was the conduct of energy audits in commercial and public buildings and the delivery of training sessions on EE (Activity 1). The second one was the development of energy efficiency standards and regulations for commercial and public buildings (Activity 2).

A team of two local energy and engineering experts was built-up to provide the international experts with local context data and assisted them in conducting energy audits, interviews, training and workshops with key national stakeholders.
The purpose of Activity 1 was to determine the existing construction practices, materials and electric systems, as well as the energy consumption pattern and levels in commercial and public buildings.

The main tasks were the following:

  • Data-gathering:
    • Conducted 30 energy audits, including commercial and public buildings, and construction sites
    • Conducted 10 to 15 interviews with local construction-sector stakeholders, including professionals and retailers and distributors
  • Data-analysis:
    • Analyzed the data obtained from energy audits and interviews to identify the key construction trends, building metrics and energy indicators
  • Conducted training workshops for EE champions:
    • Selected potential trainees, including ministries, department and agencies, municipal authorities, and stakeholders in the real estate and construction sectors
    • Selected training topics, including EE concepts and most promising EE measures, best practices in EE standards, codes and labelling schemes, methodologies for conducting energy audits, and an introduction to RETScreen

The purpose of Activity 2 was to develop energy efficiency standards and regulations for commercial and public buildings, including an EE labelling scheme for buildings.

The main tasks were the following:

  • Developed EE standards and legislative instruments for commercial and public building elements
    • Reviewed the policy and regulatory framework in place in relation to the promotion of EE in buildings
    • Identified the main barriers to the adoption of a regulatory and legislative tool and proposed actions to mitigate them
    • Identified the types of buildings to be covered by the standards
    • Conducted a climatic analysis to adjust the EE standards accordingly
    • Discussed with the local counterparts to establish the type of compliance evaluation approach(es) to be used to enforce the standards
    • Performed a series of parametric simulations with a simple EE building analysis software tool and defined cost-effective EE standards to be applied to various types of building models
  • Developed an EE labelling scheme for commercial and public buildings
    • Reviewed international and regional experience in energy labelling schemes for buildings
    • Collaborated with the local authorities in charge of the project to establish the most appropriate format and contents
  • Held consultations with local stakeholders
    • Selected potential participants, including ministries, departments and agencies, municipal authorities, and stakeholders in the real estate and construction sectors
    • Selected specific discussion topics, including the project methodology and main findings regarding current construction practices and energy consumption profile, the potential standards and legislative approaches to promote EE in buildings, the proposed EE standards and legislative instruments, the review of existing EE building labels and proposed design, the potential barriers, and the recommendations.

The AfDB is following the recommendations made by Econoler and is on the right track to accomplishing its goal of sustainably reducing greenhouse gas emissions by implementing energy efficiency standards and regulations for Ghana’s public and commercial buildings.
