Energy efficient design and construction of residential buildings


In the framework of «the Energy Efficient Design and Construction of Residential Buildings» RK Government/UNDP/ GEF Project - which a long-term objective is a greenhouse gases reduction in Kazakhstani housing sector by means of increasing the new residential buildings’ energy efficiency - a designing and construction of an energy efficient residential building pilot project’s implementation is ongoing in Karaganda.

The Primary Goal

Introduction of the international practice on energy efficient residential building designing in order to attain a considerable decrease in a building’s energy consumption and greenhouse gases emissions’ volume and also maintenance costs saving.
The residential building designing and construction are financed by the Karaganda City budget in the framework of «the Employment Program - 2020» Governmental Program on direction of a labor force mobility increase for housing of the program participants.
The UNDP/GEF project on energy efficient construction cofinances the pilot construction unit as to attraction of the international experts for energy efficient designing and construction development. The Republic of Belarus NIPTIS Scientific Research Institute named after Ataev acts in the capacity of the project’s international expert team.

The Unit’s Basic Characteristics:

Quantity of floors
Quantity of bays
Quantity of
Flats’ total area (m2)

The complex of the design arrangements aimed at the energy use efficiency increase:

  • Efficient thermal protection of external building envelopes:
    1. an absence of shifting the warmth-keeping jacket alongside of a height of walls;
    2. an additional heat insulation of external walls of an attic floor with mineral wool boards and in spots of abutment of ceilings upon external walls;
    3. heat-insulating-inserts-made-from-mineral-wool-boards installation alongside of a height of a slab in frontal zones of slabs’ bearing; a heat insulation of a plinth reinforced concrete floor;
    4. a heat insulation of the aligned overlapping of the staircase and elevator section along reinforced concrete slabs;
    5. the reduced total thermal resistance of windows RFr= 1,00 м²•°C/W.
  • An efficient engineering system:
    1. System of a forced influx-and-extract ventilation with a heat regeneration;
    2. Heating devices fitting out with automatic temperature regulators;
    3. A building’s monitoring systems’ uniform network;
    4. A horizontal system of heating distribution;
    5. apartment-by-apartment heat meters installation;
    6. The heat consumption regulation’s automated system (HCА).
  • The calculated (design-basis) rate of consumption of thermal energy used for building heating per year amounts to qhdes = 55,7 kilojoule/ (m2 - °С – a full day) that corresponds to a requirement demanded for the B "high" energy efficiency class of the consumption of thermal energy rate used for heating and ventilation when qhreq=64,8 kilojoule/ (m2 - °С – a day). A rise in the project cost caused by measures aimed at energy efficiency increase amounts to about 10 %, the cost savings resulting from measures on energy efficiency increase amounts to more than 30 %.
    Upon construction activities termination the RK Government /UNDP/GEF Project will monitor a decrease in the building’s energy intensity and greenhouse gases emissions’ reduction.
