  • Built Environment Sustainable Energy Market Review - Sustainable Energy Toolset II (BEST II)

Sustainable energy toolset II aims to update and expand the previous Sustainable energy toolset, facilitating energy efficiency screening and assessment of built environment projects within EBRD’s portfolio of investment projects. The status of the energy efficiency legislation and regulations related to the built environment were reviewed. It address different types of buildings as follow: Multi-storey apartment buildings, Family houses, Shopping malls and retail centres, Logistic centres, Offices, Hotels, Recreation and sport, Healthcare facilities, Schools, Shops.


Main activities:

  • Review of buildings related EE regulatory environment
  • Development of sustainable energy indicators of existing buildings
  • Development of check list of applicable measures with basic technical specifications
  • Development of market penetration study

Client: EBRD


Location: Albania, Armenia, Azerbaijan, Belarus, Bosnia and Herzegovina, Croatia, Georgia, Kazakhstan, Kyrgyzstan, Moldova , Mongolia, Romania, Russian Federation, Serbia, Tajikistan, Turkey, Turkmenistan, Ukraine, Uzbekistan


Duration: 10/2011 - 02/2012

  • Energy Efficiency in Buildings in the Contracting Parties of the Energy Community

Develop a Study to support governments in their efforts to meet their commitments under the Energy Community Treaty by assisting them to increase the efficient use of energy in buildings and improve their energy performances, as well as for implementation of their National Energy Efficiency Action Plans with respect to buildings sector.


ENSI providing various services to ensure good quality output of the Study:

  • A standard approach/methodology for developing a building stock inventory and a methodology for defining reference buildings in each category;
  • Based on reference buildings, estimated economic energy saving potential and optimal investment costs per category, including prioritisation of measures based on their cost effectiveness;
  • A data base (methodology and tool) for the required climate parameters used in the calculation of minimum energy performance of buildings;
  • Common methodology for calculating the energy performance of buildings according the EPBD;
  • Series of recommendations on what measures/steps are necessary to set the minimum energy performance requirements for different categories of new and existing buildings or building units and technical building systems in accordance with the requirements of the EPBD;
  • A list of minimum EU standards, and an outline of the secondary legislation that is required to be adopted in order to proper implement the EPBD;
  • A common Roadmap/process flowchart for the implementation of the EPBD;
  • Training Workshop.

  • Quick Assessment of Energy Performance of Built Environment Projects

The Quick-Assessment aims to assist EBRD on evaluation and identification of sustainable energy components in build environment projects as well as compare given project with energy performance benchmarks. The Project addresses public, residential and commercial buildings in the pipeline of Property & Tourism, Transport, Agribusiness, Municipal Teams as well as suitable projects of other Banking Teams of EBRD.

The assignment includes:

  • Development of a standard energy efficiency questionnaire for new building developments;
  • Engagement with the Clients on clarification on any technological aspects;
  • Quick-Assessment of energy performance of selected built environment projects.

Sustainable energy investments are described per the following categories: building fabric; HVAC; lighting; water saving equipment; power supply infrastructure.
Beside the energy performance assessment of the proposed projects and solutions, the project also includes evaluation of possible additional energy efficiency improvement measures:

  • Review existing technical specification and identify possible additional feasible sustainable opportunities;
  • Analyse these feasible energy efficiency opportunities and assess energy savings and carbon reductions;
  • Provide cost-benefit analysis of those additional sustainable measures selected to be recommended for implementation.

Client: EBRD

Location: CIS

Duration: 07/2010 – 07/2011


  • Enhancing sustainable energy and transition impact in built environment - Sustainable Energy Toolset

Sustainable energy toolset aims to facilitate energy efficiency screening and assessment of built environment projects within EBRD’s portfolio of investment projects. It address buildings of commercial and some public services including shopping malls, retail centres, logistic centres, offices, hotels, recreational and sport facilities, healthcare facilities, multifunctional service facilities.


ENSI developed and prepared the following materials and tools:

  • Energy performance benchmarks (space heating, domestic hot water (DHW), cooling and air-conditioning, lighting, total delivered energy, total primary energy, total emission of CO2) for 8 types of buildings: This task also included development of brief overview of building codes;
  • A checklist of applicable measures with basic technical specification and cost-benefit analysis;
  • Preparation of quick-scan software calculation tool for quick and simplified annual energy balance of public and commercial service buildings;
  • User manual for the quick-scan calculation tool.
