Energy Performance Certificates

The Energy performance certificate (EPC) shows the energy consumption and annual CO2 emissions of a building. Energy rating scale is between A (most efficient building) and G (least efficient building).

EPCs are produced using standard methods and assumptions about energy usage. This means that the energy efficiency of one building can easily be compared with another building of the same type. This allows prospective buyers, tenants, owners, occupiers and purchasers to see information on the energy efficiency and carbon emissions from their building so they can  consider energy efficiency and fuel costs as part of their investment.

  

EXISTING BUILDINGS

Since 1 June 2013, the energy performance certificate (EPC) must be provided whenever a property is rented out or sold, according to RD 235/2013.

The EPC should be calculated by simplified procedures, such as CE3 and CE3X, or general option (LIDER and CALENER). The certificate also gives specific recommendations for how to improve the performance of your property and the potential energy consumption reduction which could be achieved when recommendations are applied.

We develop the EPC of any kind of property, for more details please contact us

What is the energy performance certificate of an existing building?

The energy performance certificate for an existing building consists of one or more documents that describe how efficient the building’s energy consumption is. EPCs are produced using standard methods and assumptions about energy usage, in order to compare easily energy performance of different properties. This allows prospective buyers, tenants, owners, occupiers and purchasers to see information on the energy efficiency and carbon emissions from their building so they can consider energy efficiency and fuel costs as part of their investment. The certificate should contain at least the following information:

  • Identification of the building or part thereof that is certified
  • Indication of the recognized procedure used to obtain the energy efficiency rating.
  • Indication of the legislation on energy saving and efficiency of application at the time of its construction.
  • Description of the building’s energy characteristics considered: thermal envelope, heating and lighting, normal operation and occupation, thermal comfort conditions, indoor air quality, etc.
  • Energy efficiency rating of the building expressed by the energy label (between A and G).
  • Document of recommendations for improvement of energy efficiency.
Who needs an EPC?

Since 1st June 2013 every domestic property for sale or rent needs to have an Energy Performance Certificate. You can perform the certification of an entire building or part thereof. Should you perform the certification of an entire building, the document will be valid for each of the apartments, offices or premises included in the building. 

There are some exceptions:

a) buildings and monuments officially protected as part of a designated environment or because of their special architectural or historic value.

b) buildings or parts of buildings used exclusively as places of worship and for religious activities.

c) temporary buildings with a planned time of use not exceeding two years.

d) Industrial buildings, defense and agricultural or parts thereof, in the part for workshops, industrial processes, defense and non-residential agricultural.

e) Buildings or parts of buildings insulated with a total useful floor area of less than 50 m2.

f) Buildings purchased for major renovations or demolition.

g) Buildings or parts of existing residential buildings, whose use is less than four months a year, or for a limited time a year and with expected energy consumption of less than 25 percent of which would be of use throughout year, provided the record by declaration responsible homeowner

The label must be included in any offer, promotion and advertising to the sale or lease of the building or building unit. When the existing building is the subject of the contract of sale of all or part of the building, as appropriate, the energy performance certificate obtained shall be made available to the acquirer. When the object of the contract is the lease of all or part of the building, as appropriate, simply simple display and made available to the tenant a copy of the certificate.

Which regulation establishes EPCs?

Royal Decree 235/2013 of 5th April 2013, “Basic procedure for certification of energy efficiency in buildings”. The purpose of the basic procedure is to promote energy efficiency, using objective information to compulsorily be provided to buyers and users in relation to the energetic characteristics of buildings, in order to assess and compare their performance. 

How is the calification procedure?

The energy performance rating of existing buildings should be made by a process that has joint recognition of the Ministry of Industry, Energy and Tourism and the Ministry of Development. It can be done by the general option, through recognized software, or by any of the simplified prescriptive procedures, such as CE3 and CE3X. 

How is the certification procedure?

Once the Rating has been achieved, the technician should check the compliance of the energy efficiency rating obtained with calculated or measured data of the existing building or part thereof, elaborate the document of recommendations for improvement of energy efficiency, and issue the Energy Performance Certificate of the existing building. 

Who can issue an EPC?

According to the Royal Decree, the certificate should be issued by qualified professional technicians who are authorized to undertake building projects and thermal installations for buildings, such as architects, quantity surveyors, or engineers.

Who will monitor compliance?

The energy performance certificate of the building must be submitted by the sponsor, or owner, as appropriate, to the competent body of the Autonomous Region in energy certification of buildings, for the registration of these certifications in their area. 

The competent body of the Autonomous Region in building energy certification shall establish and implement a system of independent monitoring of energy performance certificates. The control is carried out on a random selection of at least a statistically significant proportion of the energy performance certificates issued annually.

In addition, we perform energy audits, with advice on measures to reduce consumption; we develop as well energy-efficent refurbishment projects,  that will reduce energy consumption, and thus improve the rating of a property.

NEW CONSTRUCTION

Since 2007, it is mandatory to make available to buyers or users energy performance certificate, according to RD 47/2007 (now replaced by RD 235/2013).

The EPC should be calculated by simplified procedures, such as CE2, or general option (LIDER and CALENER).  We develop the EPC of any kind of new construction.

Furthermore, as sustainability consulting, we work with design teams in order to achieve a reduction in energy consumption and thus better energy efficiency rating.
