1. Introduction According to Article 4 of Directive 2010/31/EE for the energy performance of buildings: “Member States shall take the necessary measures to ensure that

minimum energy performance requirements for buildings or building units are set with a view to achieving cost optimal levels. The energy performance shall

be calculated in accordance with the methodology referred to in Article 3. Cost optimal levels shall be calculated in accordance with the comparative

methodology framework referred to in Article 5.”

The Regulation (EU) No 244/2012 and the guidelines accompanying the Regulation, establish a comparative framework for calculating cost-optimal levels of

minimum energy performance requirements. The calculations have to be performed from a macroeconomic point of view (looking at costs and benefits of

energy efficiency as a whole) and a strictly financial point of view (looking only at the investment itself).

This report presents the calculation results for Cyprus. The calculation was performed at climatic zone 2 (as it is defined in National Methodology for

Calculating the Energy Performance of Buildings), but it can be assumed that the results also cover climatic zones 1 and 3, since different calculation tools

have proved that the calculated energy consumption in these areas is quite similar1. At climatic zone 4 (areas above 600m height) the weather conditions

differentiate from zones 1, 2 and 3, since the winter season is longer and much more severe than in the other three zones. However, more than 90% of the

population lives in climatic zones 1, 2 and 3, and for this reason the results are considered to give a fair picture about the economic effects of minimum

energy performance on the vast majority of the population.

2. Reference Buildings According to Regulation (EU) No 244/2012: “Member States are required to define reference buildings for the purpose of cost-optimal methodology. The main

purpose of the reference building is to represent the typical and average building stock in certain Member State, since it is impossible to calculate cost

optimal for every individual building.” The Regulation asks to identify one reference building for new building and at least two for existing buildings. The

reference buildings can be established either with the selection of a real example or by creating a “virtual building”.

The total dwelling stock in Cyprus2 was in 2011, 433.212 of which, 299.275 are permanent residences and 133.937 are empty or of seasonal or temporary

use. Of the 433.212 residences, 172.944 are detached houses, 59.050 are semi-detached houses, 32.893 are terraced houses and 123.557 are apartments.

32.530 are conventional dwellings in partly residential buildings

The recorded year of completion of these buildings is as follows:

• 3.968 were completed before 1919, • 9.129 were completed between 1919 and 1945, • 20.343 were completed between 1946 and 1960, • 24.255 were completed between 1961and 1970, • 61.247 were completed between 1971and 1980, • 85.503 were completed between 1981and 1990, • 70.094 were completed between 1991and 2000, • 54.897 were completed between 2001and 2005, • 74.203 were completed between 2006 and 2011.

When it comes to the size of the residential buildings in Cyprus, the mean area per dwelling there has been a decreasing trend from 184m2 in 1998 to 153m2

in 2005. Since 2005 the mean area per dwelling has remained approximately in the same level.

The total building stock in the tertiary sector 3 was approximately 81.000

Out of the 81.000 there is information for the following categories of buildings:

• 10734 are buildings used by public authorities, mainly offices

• 10355 are schools (nursing kindergarten, primary schools, gymnasiums, lyceum and universities)

• 3956 are hotels and tourist apartments,

• 603 are hospitals and medical centres.

Virtual reference building were established to represent one new single family house, one new office building, one new apartment building, two existing single

family houses, two existing office buildings, two existing apartment buildings and one existing retail building (Annex I). The buildings were created based on

the above mentioned data and statistical data regarding thermal insulation and technical systems installed in existing buildings7. Also very useful was the

input of various stakeholders.

3. Calculations Energy efficiency measures were applied on the reference buildings. The energy savings resulting from each measure was calculated using the software

SBEMcy which simulates the National Methodology for Calculating the Energy Performance of Buildings, also used to issue Energy Performance Certificates.

The National Methodology defines set point temperatures, typical outdoor climatic condition, typical functionality (Annex II), and primary energy conversion

factors (Annex III). The results derived from SBEMcy were compared with the consumption of similar real buildings and adjustment factors were introduced in

order to give pragmatic energy consumption (Annex IV).

The cost of every energy efficiency measure and the cost of energy resulting was calculated based on Regulation (EU) No 244/2012. The scope was to

calculate the Global Cost for the reference building, and then to calculate the Global Cost of different packages of energy efficiency measures applied to the

reference building. Global Cost means the sum of the present value of the initial investment cost, sum of the running costs, and replacement costs (referred to the starting year), as well as disposal costs if applicable8. The Global Cost is calculated by the following formula:

6 According to Cyprus Organization of Tourism 7 Τελική Κατανάλωση Ενέργειας στα Νοικοκυριά 2009, Στατιστική Υπηρεσία 8Source: Commission Delegated Regulation (EU) No 244/2012 of January 2012 supplementing the Directive 2010/31/EU

7

Annex V provides the cost data that was used for the calculation of initial investment cost and running cost, replacement and disposal cost. All cost data are

market based. The running cost constitutes of the energy cost and the maintenance cost. For the energy cost the average current prices were used for the

first year, and then an annual increase of 2.8% was taken into account using the estimated fuel and electricity development trends as provided for by the

European Commission on a biannually updated basis9.Annex VI provides the life span of the building, elements of the building envelope and the technical

systems, as well as the annual maintenance cost in percentage of the initial investment10. The maintenance of the technical systems was calculated based

on that percentage. The replacement cost was taken into account for the technical systems, since almost all of them have shorter life span than the building.

Considering the financial calculation, for every package a calculation was performed at 7% and 14% discount rate. The choice of these rates was

made to depict the “good” and the “bad” investment environment scenario, having in mind the current financial situation and the loan rates given by

commercial banks for housing. Considering the macroeconomic calculation, for every package a calculation was performed at 3% and 4% discount rate. The calculation period is 30 years for residential buildings and public buildings, and 20 years for non-residential buildings. Subsidies are not included in 9 Source: EU Energy Trends to 2030; update 2009. European Union 2010 10 Source: CYS EN 15459:2007

the calculation, since the primary objective of the calculation is to examine the potential of readjusting minimum energy performance requirements or to form

new.

4. Minimum Energy Performance Requirements

National minimum energy performance requirements should not be more than 15% lower than the outcome of the cost-optimal results of the calculation taken

as the national benchmark. The calculation has examined the cost optimality of the current minimum energy performance requirements as they apply for new

buildings and buildings above 1000m2 that undergo major renovation11. These are:

• Maximum U-value for roof 0.75 W/m2K

• Maximum U-value for wall 0.85 W/m2K

• Maximum U-value for floors in contact with external environment 0.75 W/m2K

• Maximum U-value for floors in contact with closed unheated space 2.00 W/m2K

• Maximum U-value for windows 3.80 W/m2K

• Average U-value 1.30 W/m2K for residential buildings

• Average U-value 1.80 W/m2K for residential buildings

• Energy Performance Certificate with energy class at least B

• Solar heater for hot water supply (only for residential buildings)

• Providence for installing a system that generates power from RES

Also, the calculation has examined the implementation of minimum energy performance requirements for buildings that are below 1000 m2 and undergo major

renovation and for building elements that form part of the building envelope when they are replaced or retrofitted as it is derived from article 4 of Directive

2010/31/EU.

5. Results The following tables show the results of calculation from the financial and the macroeconomic point of view. Annex VII gives graphs of the most important

calculations, as well as graphs of the calculation results of the same variants but with different discount rates, which are not recorded at the tables. The

comments on the plan for readjusting the gap between an existing minimum requirement and the cost optimal solution, and the comments for implementing

new requirements to existing building that undergo major renovation are subject to public consultation and Ministerial approval, and cannot be considered

binding.

Gap

666 145 - 180 No requirements N/A

Justification of the gap: No gap Plan to reduce the non-justifiable gap: The range of the calculated primary energy of the building according the MAEPB lies within the B energy class of the Energy Performance Certificate (EPC). The cost optimal range is represented on variants 6,7,12 and 13. The plan is to propose as minimum requirement to be at least energy class B for a single family building that is undergone major refurbishment. The various measures that constitute variants 6,7,12 and 13 can be guidelines and not mandatory measures, since existing buildings have particularities that may make the implementation of these measures not feasible.

Table 9

Basic reporting table for energy performance relevant data – Existing single family building B

The MAEPB has been developed according to the Law that Regulates the Energy Performance of Buildings. Software SBEMcy is the tool that simulates MAEPB and is used for issuing Energy Performance Certificates. The calculation method complies with the umbrella document PG-N37, which lists standards relevant to the implementation of the EPBD. In particular EN ISO 13790 deals with Energy performance of buildings – Calculation of energy use for space heating and cooling. The Guide for the Thermal Insulation of Buildings is the approved document for calculating U-values for building elements and it complies with EN ISO 6946, EN ISO 13370, EN ISO 10077-1 and EN ISO 10456.

Gap

321 82 - 187 No requirements N/A

Justification of the gap: No gap Plan to reduce the non-justifiable gap: The range of the calculated primary energy of the building according the MAEPB mainly lies within the B energy class of the Energy Performance Certificate (EPC). The cost optimal range is represented on variants 12 and 15. The plan is to propose as minimum requirement to be at least energy class B for a single family building that is undergone major refurbishment. The various measures that constitute variants 12 and 15 can be guidelines and not mandatory measures, since existing buildings have particularities that may make the implementation

Gap

537 226 - 252 Up to 234 No gap

Justification of the gap: No gap Plan to reduce the non-justifiable gap: The range of the calculated primary energy of the building according the MAEPB mainly lies within the B energy class of the Energy Performance Certificate (EPC). The cost optimal range is represented on variants 15 and 19. The plan is to propose to maintain the minimum requirement to be at least energy class B for an office building that is undergone major refurbishment. The various measures that constitute variants 15 and 19 can be guidelines and not mandatory measures, since existing buildings have particularities that may make the implementation

Comparison table for both new and existing buildings - Existing retail building

Reference building





Gap

822 158 – 184 No requirement N/A

Justification of the gap: No gap Plan to reduce the non-justifiable gap: The range of the calculated primary energy of the building according the MAEPB mainly lies within the A energy class of the Energy Performance Certificate (EPC). The cost optimal range is represented on variants 8, 9 and 10. The plan is to propose to a minimum requirement to be at least energy class B for a retail building that is undergone major refurbishment. The various measures that constitute variants 8, 9 and 10 can be guidelines and not mandatory measures, since existing buildings have particularities that may make the implementation of these measures not possible in certain buildings.

Table 40

Comparison table for both new and existing buildings – New single family house

Reference building





Gap

479 112 - 243 Up to 207 No gap

Justification of the gap: Plan to reduce the non-justifiable gap: The range of the calculated primary energy of the building according the MAEPB mainly lies within the B energy class of the Energy Performance Certificate (EPC). The cost optimal range is represented on variants 20, 23, 24 and 28. This minimum requirement is proposed to remain the same.

Justification of the gap:

Plan to reduce the non-justifiable gap: The calculation of the roof insulation as a single measure in a new building indicates that the cost optimum level is 0,39W/m²K. However, the global cost between 0,19 and 0,81 W/m²K show very small incremental changes. It is proposed that the new minimum requirement for roofs is 0.63 W/m²K.

The MAEPB has been developed according to the Law that Regulates the Energy Performance of Buildings. Software SBEMcy is the tool that simulates MAEPB and is used for issuing Energy Performance Certificates. The calculation method complies with the umbrella document PG-N37, which lists standards relevant to the implementation of the EPBD. In particular EN ISO 13790 deals with Energy performance of buildings – Calculation of energy use for space heating and cooling. The Guide for the Thermal Insulation of Buildings is the approved document for calculating U-values for building

213

elements and it complies with EN ISO 6946, EN ISO 13370, EN ISO 10077-1 and EN ISO 10456.

Table 83

Basic reporting table for energy performance relevant data – New office building




The MAEPB has been developed according to the Law that Regulates the Energy Performance of Buildings. Software SBEMcy is the tool that simulates MAEPB and is used for issuing Energy Performance Certificates. The calculation method complies with the umbrella document PG-N37, which lists standards relevant to the implementation of the EPBD. In particular EN ISO 13790 deals with Energy performance of buildings – Calculation of energy use for space heating and cooling. The Guide for the Thermal Insulation of Buildings is the approved document

285

for calculating U-values for building elements and it complies with EN ISO 6946, EN ISO 13370, EN ISO 10077-1 and EN ISO 10456.

buildings W/m²K

Gap

2,16 0,24 – 0,47 Up to 0,75 108%

Justification of the gap: Plan to reduce the non-justifiable gap: The calculation of the roof insulation as a single measure in a new building indicates that the cost optimum level is 0,36 W/m²K. However, the global cost between 0,24 and 0,47 W/m²K show very small incremental changes. It is proposed that the new minimum requirement for roofs is 0.63 W/m²K.
