Introduction

Pursuant to Article 4(1) of Directive 2010/31/EU on the energy performance of buildings (the

‘Directive’), Member States must ensure that minimum energy performance requirements

are set with a view to achieving cost-optimal levels. This paragraph also provides for a

review of these requirements at regular intervals no longer than five years. The previous

assessment was submitted by Hungary to the European Commission in March 2013. That

Report showed the need for more stringent requirements. The relevant Decree No 7/2006 of

the Minister Without Portfolio of 24 May 2006 on the determination of the energy

characteristics of buildings (the ‘Decree’) was supplemented accordingly by adding Annex 5

on cost-optimal requirements (the ‘COR’). The COR came into force on 1 January 2015 in

relation to investments implemented using national and EU funds aimed at energy savings

or support from the central budget. As of 1 January 2018, the COR has become mandatory

for all investments falling within the scope of the Decree.

As five years have elapsed since March 2013, another review is required. The method of

reviewing and reporting is provided for under Article 5 of the Directive. In accordance with

this Article, the Commission adopted Regulation (EU) No 244/2012 supplementing Directive

2010/31/EU of the European Parliament and of the Council on the energy performance of buildings by

establishing a comparative methodology framework for calculating cost-optimal levels of minimum

energy performance requirements for buildings and building elements (the ‘EU Regulation’), the

method set out in which was used as a basis for this Report.

Executive summary

Due to the combined effect of the reduction in energy prices and the rise in the price of

building materials and construction services, the optimal level of U values determining the

thermal insulation of buildings is showing lower energy efficiency than before. The

requirements adapted to the previous optimal values therefore easily comply with the

Directive. This effect proved to be more moderate for overall energy performance (the Ep

value) indicating the energy consumption of the whole building. The level of energy

efficiency set forth in the requirements in this context is 15 % higher on average than the

absolute optimal level. Accordingly, the requirements laid down in the Decree are in

conformity with those in the EU Regulation and, therefore, no further measures are

required.

Major changes since the previous report in 2013

The calculation of optimal levels was performed by updating the data items in Hungary’s

2013 Report1. The reference buildings and improvement packages have been maintained. The

analysis carried out for this update mostly takes into account the state of affairs in 2017,

depending on available data.

As compared to the 2013 Analysis, which calculated energy demand (Ep) using the

calculation method applicable in 2012, there have been several changes, the most relevant of

which include, but are not limited to, the following:

air exchange from the lack of airtightness is now taken into account,

boiler energy efficiency has been modified in certain cases,

the domestic hot water generation (DHWG) resource has decreased for certain single family buildings,

the energy demand of internal heat load and lighting has been changed,

the calculation method for heat recovery from air has been changed,

There have also been significant changes in investment costs between 2012 and 2017:

the costs of constructing complete building constructions for new buildings have increased by 14-17 %,

the doors and windows market has been restructured, and related costs have typically increased by 10-20 %,

the installation costs of thermal insulation have increased by 20-40 %,

the costs of technical building system and electric system investments have increased by 7-12 %.

Another major change is that only Class A2 non-combustible facade thermal insulation

systems may be installed on tall buildings. This applies only to TH-2 buildings made of

precast concrete panels, and the replacement of thermal insulation material causes further

price increase.

Unlike in the 2013 Report, the partial and final results of energy calculations and cost

calculations are presented together. This means that they are not included in Annexes 1 and

2 but are all presented in Annex 6 by building type.

Initial data on reference buildings and packages

No essential changes have occurred in the building categories included, in their geometric

characteristics or in the initial technical facilities as compared to those in the 2013 Report.

However, there have been changes in the standard use of a number of types of technical

building system equipment and their calculation methods. As of 1 January 2015, windows

installed under an energy efficiency grant scheme must have a thermal transmittance (Uw) of

1.15 W/m2K. The market has been reorganised due to the efforts to adapt to the new

1 Calculations for the establishment of the cost-optimal level of energy performance requirements for buildings, 2013, Energiaklub, Krisztina Severnyák, Orsolya Fülöp

5

requirements. The window type with Uw=1.6 W/m2K previously assessed has almost

completely disappeared, and has therefore been replaced by windows with Uw=1.4 W/m2K

in this assessment. In addition, windows with Uw=1.3 W/m2K have been replaced by ones

with Uw=1.15 W/m2K.

Further details are presented in Annexes 1, 2, 3 and 4. It should be noted that additional

variants were assessed for some building categories in terms of technical issues and solar

cells.

Costing

The costs of investment components are included in Annex 5.

For investor calculations the following cost data were taken into account in respect of energy carrier

prices.

Type of energy carrier

Price of energy carrier (HUF/kWh)

natural gas 11.8

electricity 37.1

district heating 14.1

district heating, institution 17.1

firewood 9.9

wood pellets 15.3

Table 0.1

Except for firewood and pellets, the prices of energy carriers for the first year of the

assessment were provided by the Hungarian Energy and Public Utility Regulatory Authority

based on the national average prices. Table 0.1 includes a sales tax of 5 % for district heating

and 27 % for other energy carriers.

Energy carrier

solar energy, wind energy, hydropower, geothermal energy (other than heat pumps)

0

CO2 emissions were taken into account for the macroeconomic analysis with the values in

Table 0.2. The same values had been used previously for the evaluation of grants. These

values only include CO2 released by burning energy carriers in appliances (boilers, turbines,

etc.) installed in the territory of the country and exclude emissions from the production and

transportation of energy carriers. Another important fact, from the perspective of

macroeconomic analysis, is that the district heating provider receives state aid for residential

consumers. In respect of the aid paid for district heating in 2016, the average amount per

energy carrier was 6.28 HUF/kWh, which increases macroeconomic price data as compared

to those in Table 0.1. This aid applies to reference building TH-2.

The pricing used for the calculation of global costs was based on the following values.

Determining energy demand and global costs

In accordance with the experience gained during previous analyses, the partial and final

results of both energy demand calculations and cost calculations are now presented in the

same table to increase transparency. Thus, these data are included by type in Annex 6.

The assessment of the variants’ reasonableness has been made more transparent by

introducing further parameters. We introduced:

the parameter ‘investment (HUF/m2)’ which expresses the initial cost of an

improvement variant calculated for useful floor space, and helps to determine which

building categories require the highest unit costs;

the parameter ‘costs of savings (HUF/kWh)’ which expresses the costs of an

improvement variant calculated for the amount of energy saved, and helps to

determine which variants are suitable to ensure considerable savings at the lowest

costs;

the parameter ‘static payback time (a)’ is the investment cost divided by the value of

energy price reduction achieved in the first year (it excludes the discount rate and

7

the increase in energy price, but includes maintenance costs), and assists in investors’

decisions and helps to assess the acceptability of a variant;

the parameter ‘static global costs (HUF)’ is the sum of initial costs, maintenance

costs, and the energy costs of the first year as multiplied by 20 or 30 and helps to

verify sensitivity analysis. In other words, it is a simplified verification model

calculated using a discount rate of 0% and an energy price increase of 0 %.

The absolute optimal levels determined by each costing model are marked with a red

background in Annex 6. Similarly to the 2013 Analysis, the comparison is also shown in a

graph.

Assessment of variants by reference building

On the basis of Annex 6, the following statements can be made.

CSH-1: Existing single family building; loam

This type of building constitutes about 10 % of the residential building stock. As regards the

building envelope, optimal levels were typically obtained with medium-level improvement

packages No 8 and 11 (U=1.15 W/m2K for windows, 0.35 for walls, etc.). For the majority of

price models, variant No 11 including the abovementioned renovation of building

constructions combined with technical improvements, i.e. the replacement of the heating

installation represents the optimal level. However, it should be noted that in contrast to the

burning of purchased firewood as assumed in the calculation model, a considerable amount

of wastes produced in and around the house may be used in such buildings for energy

purposes. Nevertheless, the energy performance upgrading of these buildings is justified

precisely because burning wastes can cause significant health impairment.

CSH-2 Existing single family building, small-sized brick

Due to the similarities with reference building CSH-1, the same findings can be made in

respect of the building envelope, with the addition that the assessment of CSH-2 also

included technical building system packages used more widely, such as heating with natural

gas. Upgrading to such an appliance is more likely with this reference building than with

CSH-1. From the standpoint of an investor, a changeover to heating with natural gas appears

to be more favourable. The costs of connection to the natural gas network and the

construction of pipelines were not taken into consideration in the analysis. Variant No 11

with natural gas heating is still an optimal solution for the E1 D3 I price model even when

this cost is estimated at HUF 0.5 million. However, a changeover to natural gas is no longer

optimal where the connection and development fee is estimated at HUF 1 million. In that

case, variant No 14 would represent the optimal level, implying that – similarly to CSH-1 –

advanced wood burning is optimal under such conditions. From a macroeconomic

perspective, maintaining wood burning along with the modernisation of building

construction and technical building systems typically gives the optimal solution. Assuming a

high increase in energy price and a low discount rate (E2 D3 I and E2 D3 M), variant No 19

8

with solar cells proves to be the optimal solution when combined with a complex renovation.

Further details on the optimal values provided by solar cells can be found under CSH-6.

CSH-3 Existing single family building, B30 brick

This reference building is very similar to the previous two. However, an important difference

is that here gas convector heaters installed in each room are assumed as an initial system.

Despite the low (76 %) efficiency of a gas convector heater, the improvement of the technical

building system would not be optimal; instead, the renovation of the building envelope can

be considered to be the optimal solution, just as with the two previous options. Above

variant No 10, the replacement of existing gas convector heaters is not optimal even when a

lower initial efficiency of 71 % is taken into account in the calculation. However, it should be

noted that the simplified method referred to in the Decree does not take into account the

operation of a boiler at partial load, which could in practice completely nullify the reduction

in energy demand gained through the renovation of the building envelope. If a reduction in

efficiency of at least 15 % occurs seasonally due to the part load of the heat generating

appliance, the improvement of the technical building system becomes cost-effective. In this

case, the optimal value would be 136 kWh/m2 with variant No 11.

In summary, we should not conclude that it is not worth replacing a gas convector heater

with a more modern heating system in a single family building.

CSH-4 Existing single family building, holed brick

Similarly to the previous study, variant No 11, i.e. a combination of medium-level thermal

insulation, improvement and boiler replacement remains the optimal solution for this single

family building typical of the 1980s.

CSH-5 Existing single family building, Porotherm brick

For this 1990s reference building, extensive renovation has not proved to be optimal.

However, variant No 19, which includes only the replacement of the boiler, was found to be

favourable. From a macroeconomic perspective, the installation of a solar collector under

variant No 18 gives the optimal solution at a discount rate of 3 %. Accordingly, boiler

replacement should be supported for newer buildings in combination with the installation of

a solar collector.

CSH-6 New single family building, Porotherm brick

The optimal solution for this newly built reference building was again medium-level thermal

insulation and windows, which are represented by variant No 15 with a consumption of

132 kWh/m2a. This should be compared to a typical new single family building certified in

2017 with a consumption of 127 kWh/m2a, although a consumption of 230 kWh/m2a was

still accepted. Consequently, the regular construction practice reflects the cost-optimal level.

For certain price models a more advantageous thermal insulation also proved to be optimal

(variants No 18 and 20). These can comply with the COR, which came into force in 2018 for

9

all building types, with respect to the U value as well. As a result, COR requirements impose

an extra cost of less than 2% on builders as compared to the 2017 average.

Supplementing a technical building system with a heat recovery system, a heat pump or a

solar collector was not found to be optimal either. With an investor model, a solar cell (PV) is

only considered optimal when there is a significant price increase and low discount rate;

however, it is not optimal for the model E1 D3 I which was taken into account. It should be

noted that this study calculates with a 10-year lifecycle for inverters instead of the 5-year

lifecycle assumed in the previous one; even so, a solar cell is only found to be optimal under

favourable funding conditions.

Variant No 18 represents an exceptional combination where a 1.15 W/m2K window is paired

with a 0.22 W/m2K non-transparent building envelope package instead of a 0.35 W/m2K

one, and has more advantageous technical building system control than variant No 1. From a

macroeconomic perspective, this variant is the optimum level for several models.

Variants No 13, 14, 20 and 21 comply with the requirements for nearly zero-energy buildings

(NZEB), which are set out in Annex 6 to the Decree. Out of these, variant No 20 gives the

optimal solution. The requirements for the share of energy from renewable sources are laid

down in Part IV of Annex 6 to the Decree. The amount of renewable energy sources required

for this variant is 19.3 kWh/m2a, while the current amount of renewable energy sources is

23.9 kWh/m2a. Due to a 10-year lifecycle assumed for an inverter, this variant proved to be

the optimal level for a number of price models. When calculating with a lifecycle of 7 years,

this variant is only optimal with E2 D3 M. However, the application of a solar cell will not

represent the optimal solution in any of the cases when a lifecycle of 5 years is assumed. In

such cases, No 18 replaces No 20 as the optimal variant. It is apparent from the above that

the lifecycle of an inverter is of key importance in terms of the energy efficiency of buildings.

By comparing variant No 15 with No 20 it can be observed that an extra cost of 6 % is

required for an NZEB as compared to an average building built in 2017.

TH-1 Existing apartment block, ten-storey, precast concrete panels

Since 2012, a facade thermal insulation system with an A2 fire rating is required for tall

buildings. This requirement only applies to this reference building out of those assessed. As

a result of this stricter level of fire prevention, a rock-wool thermal insulation with a higher

price had to be taken into account for this reference building. Nevertheless, variant No 11

which includes complex renovation continues to be the optimal level. From a

macroeconomic perspective, the use of a solar collector was found to be optimal in one case,

and therefore, support for its installation is justified.

TH-2 Existing apartment blocks with outside corridor made of brick

Similarly to CSH-3, gas convector heaters were taken into consideration in the calculation.

10

The same level of thermal protection (1.15/0.35) has proved to be optimal. However, for this

reference building the improvement of the technical building system with the installation of

a central-heating boiler (variant No 11) was also found to be optimal. The reason why this is

very beneficial is that a facade flue outlet in such buildings carries a serious risk to the health

of individuals and the condition of the building due to the closed urban street structure and

air shafts and atriums. Nevertheless, the replacement of old gas convector heaters with new

ones as an independent solution under variant No 17, as well as this option combined with

thermal insulation and window replacement under variants No 18 and 19, were also

assessed. The installation of a new gas convector heater was not found to be optimal in any

case but it at least ensures lower global costs as compared to leaving the heating system

unchanged. Another reason why supporting the individual replacement of gas convector

heaters with facade flue outlets is not practical is that during a subsequent installation of

thermal insulation the heaters would have to be removed and then reinstalled, which

requires two visits and is done at a high cost. The same applies to the improvement of

thermal protection only.

TH-3 New multifamily building made of Porotherm brick

Similarly to the previous assessment, the initial variant has proved to be the optimal with a

consumption of 138 kWh/m2a. Variants 13, 14 and 15 were also assessed in respect of the

minimum share of energy supplied from renewable sources. It was found that variants 14

and 15 comply with the U value requirements for nearly zero-energy buildings.

Out of these three options, 14 represents the optimal level. With this variant, the amount of

renewable energy sources required is 18.4 kWh/m2a, while the current amount of renewable

energy sources is 32.4 kWh/m2a, so this variant easily complies with the renewable energy

requirements. In the case of E1 D3 I, global cost is only 3 % higher than the optimal level. In

the case of E2 D3 M, global cost is even lower than the initial state.

I-1 Existing school building made of precast concrete panels

Here it was once again the most typical variant No 8 with medium-level building

construction improvement and without technical upgrading that proved to be optimal. No

sufficient return is provided by variants No 10 to 13, i.e. the combined application of control,

the replacement of heat transfer appliances, the improvement of the domestic hot water

system, the modernisation of lighting, the installation of a heat recovery air handling system;

for these variants even the global cost of the initial state is lower.

I-2 Existing school building, made of brick

Here, too, it was the most typical variant No 8 with medium-level building construction

improvement and without technical upgrading that proved to be optimal. In the same way

as for I-1 but also including a boiler replacement, technical improvements did not prove to be

cost-effective. For this reference building, a technical improvement simpler than that in

variants 15 to 17 including the replacement of boilers, heating control, the replacement of

11

heat transfer appliances, modernisation of lighting and control has also been assessed.

Although these variants have not been found to be optimal either, at least their global costs

were lower than those of the initial state.

I-3 New school building made of brick

It is worth mentioning that while the renovation of school buildings referred to in the above

two cases does occur from time to time, the construction of a new school building is

uncommon. Accordingly, there is no such thing as ‘an average new school building’ as with

new residential buildings CSH-6 or TH-3.

True to form, non-transparent building construction to meet medium level requirements was

found to be the optimal level. However, in contrast to the results of other assessments, the

optimal solution for windows proved to be the less stringent variant No 5. This is likely due

to the very high energy efficiency of the initial technical building system.

Although each variant from 9 to 16 is compliant in respect of the Ep value, only those with

the 0.22 package meet the requirements for non-transparent building envelopes. However,

not all of these have a sufficient share of energy from renewable sources. The requirements

for nearly zero-energy buildings are fully complied with by variants 14 and 16. From the two

NZEB variants, No 16 represents the optimal level where the amount of renewable energy

sources required is 14 kWh/m2a and the current amount of renewable energy sources is 19

kWh/m2a.

IR-1 Existing office building made of brick, with rendered facade

Exceptionally, the renovation of the building construction to meet the previous requirements

introduced in 2006, i.e. variant No 7, was found to be the optimal solution. Variants with

technical upgrades including the installation of an air handling system and a heat recovery

system were not optimal in this case either, but at least variants No 10, 11 and 12 provide

lower global costs than the initial state.

IR-2 Existing office building made of brick, with stone-clad facade

As is usual, medium-level improvement package No 8 is considered to be the optimal level.

It is important to note that no facade thermal insulation is installed for this variant. Unlike

for reference building IR-1, the global costs of the initial state are not improved by the

complex upgrading of the technical system.

IR-3 New office building

In the same way as with I-3, an optimal solution was given by variant No 5 to meet medium-

level requirements, which only includes the replacement of non-transparent building

constructions with improved ones. Considering that both I-3 and IR-3 have an advanced

initial technical system, it can be concluded that the optimal solution requires only a slight

12

improvement in thermal insulation, as compared to the 2006 state. In other words, a less

advantageous technical system calls for better thermal protection, while a modern technical

system only needs medium-level thermal protection to give the optimal level.

The Ep requirements for nearly zero-energy buildings are complied with by variants No 6

and 9 to 13. Out of these variants only No 6, 9, 12 and 13 comply with the requirements for

thermal insulation. However, the requirements for the share of renewable energy sources is

only met by variant No 13 where the amount of renewable energy sources required is

21 kWh/m2a and the current amount of renewable energy sources is 23.1 kWh/m2a.

Summary of the variants To summarise the above chapter, the following conclusions can be drawn:

The improvement of residential buildings

For residential buildings built before 1990, a package with medium-level thermal insulation

and the replacement of windows (1.15/0.35) proved to be the optimal level. In the majority

of cases, variant No 11, in which the improvement of the technical building system is

combined with the modernisation of the building envelope, is the optimal solution. In the

exceptional case of reference building CSH-3 it is assumed that – due to the operation of the

boiler at part load – the optimal solution would in fact be improvement also including a

renovation of the technical building system, but this could not be demonstrated because

operating at part load is not taken into consideration in the Decree. With a high increase in

energy prices and a low discount rate, the installation of solar cells is also advantageous, just

as it was found in the case of CSH-2. From a macroeconomic perspective, the installation of a

solar collector may also be beneficial.

The improvement of institutional buildings

The modernisation of the technical building system and electric system of an institutional

building provided varying levels of effectiveness. In most cases it was not the optimal

solution; such renovations are always advised to be reviewed on a case-by-case basis using

cost-benefit analyses. Other than that, the installation of thermal insulation and the

replacement of windows proved to be optimal. In view of the fact that, in this case,

modernisation is considered to be major refurbishment under the regulations in force, the Ep

requirements must also be met. Therefore, a partial improvement of the technical building

system and electric system may also be necessary.

The compliance of new buildings with NZEB requirements

In respect of the U value, packages including 1.15 windows and 0.22 non-transparent

constructions are able to meet the NZEB specifications. These solutions show optimal values

for certain price models. Ep requirements are discussed in the next chapter. In the context of

the required share of renewable energy sources within a nearly zero-energy building, the

13

optimal level could be approached and, with the model E2 D3 M, even reached in several

cases primarily through the installation of solar cells. This was partly due to the fact that the

inverter’s assumed lifecycle was increased to 10 years, as it was explained in the section on

reference building CSH-6. Furthermore, the beneficial feed-in tariff is also an important

factor with respect to solar cells. However, a prerequisite for this is that the users of a

building should feed no more electricity back into the network than they use in a year

(balance measurement). The burning of firewood has not been assessed for new buildings;

however, it can be seen from the evaluation of existing buildings that it is also beneficial. The

extra investment cost required to make the optimal solution fully compliant with NZEB

requirements is 5 to 10 % as compared to the construction practice in 2017, not taking wood

burning into consideration.

The relationship between the optimal level of overall energy performance

(Ep value) and the respective requirement

The optimal levels determined for each costing model and reference building are

summarised in Annex 7. Below that, the requirements for each reference building are

presented in the row ‘Ep requirement’.

As described in the Introduction, these requirements include the COR requirements laid

down in Annex 5 to the Decree for each improvement package.

It should be noted that the COR requirements apply to all building permits and simple

notifications submitted after 1 January 2018 or, where these are not necessary, construction

works commenced after that date, in the case of buildings falling within the scope of the

Decree. Accordingly, in addition to the improvement of existing buildings, they also apply to

new buildings.

Meanwhile, the requirements for nearly zero-energy buildings – as set out in Annex 6 to the

Decree – came into force on 1 January 2016. Occupied buildings have to become NZEB by

31 December 2020 or, for buildings to be used or owned by authorities, by 31 December 2018

(the ‘deadline’). Therefore, a building planned to be put into use after the deadline should be

designed and constructed on the basis of NZEB requirements. Having regard to the

imminence of the deadline and the fact that several years may elapse between the designing

of a building and the time it becomes suitable for use, a building is to be designed today to

meet the NZEB requirements. Accordingly, the comparison of new buildings in Annex 7 is

based on the NZEB requirements instead of the COR.

The difference, as a percentage, compared to these requirements is presented in the rows

below each requirement. The model E1 D3 I is used to establish the optimal values, which

are shown in bold. The highest derogation from the optimal level in each case is +6 %, while

the average is -15 %. This means that the requirements typically differ from the optimum in

14

favour of a lower environmental load and a safe use of resources. Compared to the present

cost-optimal level, the requirements represent 15 % higher energy efficiency, on average. It is

mostly the renovation of school buildings where the required values of energy performance

were found to be too strict.

From the perspective of the assessment, it has to be noted that no thermal insulation was

assumed for reference building IR-2 (a historical office building) due to its ornamental

facade; therefore, the level of renovation of the building envelope is below 25 % and the

project is not considered as ‘major refurbishment’. Accordingly, it is not subject to the Ep

requirement, making it irrelevant from the perspective of the review of that requirement.

In the sensitivity analysis, the 15 % threshold was exceeded for certain reference buildings by

the cost model E2 D3 M (high price increase, low discount rate, macroeconomic approach),

which is the most favourable in terms of energy efficiency measures. Optimal levels with an

energy efficiency exceeding the requirements can also be found for models E1 D3 M and E2

D3 B, mostly due to the variants that include solar cells. For other models, the requirements

represent an energy efficiency greater than the optimal value. In the case of the E1 D3 I

pricing model chosen for the assessment, which is the most typical of today’s conditions,

the requirements comply with the provisions laid down in Articles 4 and 5 of the

Directive for all types.

The optimal level of thermal transmittance (U) and its relation to the

requirements

Annex 8 summarises the optimal values determined by each costing model and reference

building, where optimisation is examined separately for windows and non-transparent

structures. Thus, the optimal level for windows was the one with the lowest global cost out

of variants No 1, 2 and 3.

The optimum for non-transparent structures was represented in the case of renovation by the

variant with the lowest global cost out of variants No 4, 5 and 6, while in the case of new

buildings, variant No 4 was replaced by No 1.

In Hungary, U value requirements are not dependent on either the geometry or the purpose

of the building or on whether the building is renovated or newly built. Furthermore, the

COR and the NZEB provisions uniformly use the same U value requirements. In addition,

only three types of packages per building construction type were assessed for the U value.

For these reasons, the most accurate result is obtained by examining which package is found

to be optimal most often. This is examined in the range ‘Number of optimal cases’ on the

right side of the Table, summarising all the optimal values of the sensitivity analysis.

A weighted average of these values was taken into account when making the comparison

15

with the requirements. In the case of windows, the variant complying with the requirement

of U=1.15 W/m2K which occurs uniformly for both the COR and the NZEB requirements

was found to be optimal about 1.5 times more frequently than the variant where U=1.4

W/m2K. The 1.4 variant gave the optimal solution for new buildings, due to the favourable

technical facilities of the initial building. A ‘passive house window’ with U=0.8 W/m2K was

not optimal in any of the cases. Accordingly, the weighted average was U=1.24 W/m2K. The

energy efficiency of the U=1.15 W/m2K requirement is 8% higher than this. The assessment

of non-transparent structures shows much larger variance than for windows. The energy

efficiency represented by the weighted average for walls is 42% lower, for slabs (attic, roof)

22% lower and for basement slabs 25% lower than the required value.

Determining a lower U value is not justified as the existing values represent a sufficiently high

energy efficiency. The requirements set out in the Decree for the thermal transmittance factor,

applicable as of 1 January 2018, comply with the provisions laid down in Articles 4 and 5 of

the Directive.
