Building Energy Efficiency Passport 2020

The energy passport of a building is developed in accordance with the regulation on the rules of registration of the passport of energy efficiency of buildings during reconstruction or new construction in order to calculate the physical and technical condition of the building and to obtain real information about the physical and technical condition of the building.

  The building energy passport contains the following information: the geometric characteristics of the building, the thermal performance of the exterior enclosure structures of the study object, and the energy performance of the building.

  The energy passport of the building also contains permissible normative indicators of thermal and energy characteristics of the building, which enables the control bodies, investors or buyers to understand to which class of energy efficiency this house belongs and what energy saving measures should be taken in the near future.

Since 2016, mandatory certification of the energy efficiency of existing buildings has been introduced. And since 2019, energy certification by a certified energy auditor has become mandatory. But the development of an energy passport remained part of the design and audit work.

So an energy passport is made when compiling an energy efficiency section when designing new homes or renovating, upgrading existing ones.

The production of an energy passport is for the purpose of assessing the exact energy performance of buildings, comparing the calculated indicators with the current standards and finding ways to improve the energy efficiency of the object.

The development of a passport for the energy performance of a building is made upon request of the building owners or the authorities.

When developing recommendations for improving the performance of a building, it is imperative to develop a feasibility study for the solutions.

 The energy efficiency passport in accordance with DSTU-NB А.2.2-5: 2007 has the form established

An example of an energy passport that displays the following data :

• Location, exact address of the building;

• General data of the calculated area of ​​the object of their functional purpose and characteristics

• Comparison to the minimum requirements for heat transfer resistance of the respective building.

• Calculated or actual energy efficiency indicators calculated in accordance with current standards.

• Overall energy efficiency class of the facility;

• List of energy efficiency measures and justification

• Last name, the name of the specialist who compiled the document and its certificate number.

Certification of energy efficiency is one of the necessary steps to ensure the required level of energy consumption of the building. The Energy Efficiency Passport includes three key parts: calculating and justifying compliance with the regulatory requirements, verifying the energy performance of the facility during operation and encouraging building owners to reduce energy consumption.

An energy certificate is developed on the basis of the energy passport, which substantiates the quality of the object in the real estate market.

The certification has the following structure:

 1) Calculation:

• Geometric characteristics, volumes, surfaces of the object with the definition of the heated area; 
• Calculation of the exact heating period according to the climate of a certain region, indicating the internal temperature according to sanitary and hygienic standards;
• Energy consumption and energy losses on the microclimate support systems, taking into account the methods of regulation, location and energy source consumed in the engineering systems of the building; 
• characteristics of thermal radiation of the outer walls and shells, setting the value of thermal insulation of both the individual elements and the object as a whole;
• specific energy consumption for heating and calculation of consolidated energy parameters;
• compliance of energy indicators of the house with the standards according to the legislation.

  2)  Definition:

•     structural, three-dimensional or engineering changes in the built house in comparison with design decisions;
•     the actual level of energy consumption in the first year after commissioning;
•     comparison of operational and calculated thermal and energy characteristics.

  3)  Labeling and certification:

•     energy efficiency class and home energy certification;
•     planning and justification of energy efficiency measures.
