Energy Audit

Echipa noastră, formată din  auditori certificaţi şi autorizaţi oferă servicii de auditare termică şi energetică atât pentru locuinţe individuale cât şi pentru ansambluri rezidenţiale, clădiri de birouri şi spaţii comerciale.

In addition to our activity we conduct thermal and energy expert examinations of various types of buildings: individual dwellings, residential developments, office buildings and business premises. 

Our experts are certified for all the stages of the thermal and energy evaluation process, starting from the evaluation of the thermal, technical and functional features of the building with a view to issuing the energy certificate to the generation of the energy audit report

The main purpose of the building energy certificate is to provide to the owner or user and to any person that is interested in buying or insuring the building certified information about the energy performance of the building and of the relevant interior installations. 

The energy performance of a building is determined according to a calculation methodology and is given by one or several numeric indicators that are calculated taking into consideration the thermal insulation, the technical features of the building and of the installations, the design and the location of the building in relation to the weather elements, the exposure to sun and the influence of the neighbouring buildings, any individual sources of energy and other factors, including the interior temperature condition of the building, which has influence on the necessary energy.

The energy audit analyzes the results achieved after making the thermal analysis of the building and finds efficient solutions both in technical and financial terms for the thermal and energy revamping thereof.

The obligation to have the energy certificate is provided in the Law no. 372/2005 on the energy performance of buildings and in the Order no. 1459/2007 approving the Methodological Rules on the energy performance of buildings, issued by the Ministry of Development, Public Works and Housing.

The energy performance certificate of a building is a technical document for information purposes that certifies the energy performance of that building.

In the European Union, the EC Directives 91/2002 and 31/2010 regulate the obligation that all the building categories must have energy certificates to show the energy consumption efficiency. Such directives apply to all the members states and also to those in the accession process. 

The simplified methods for calculation of the heat requirements are based on the European Standards EN 832 and EN ISO 13790, which were designed to unify the concept of energy consumption in the building sector and to compare the performances thereof. 

In Romania the obligation to obtain the energy certificate is set out in the Law no. 372/2005 on the building energy performance and the Order no. 1459/2007 approving the Methodological Rules on the energy performance of buildings, issued by the Ministry of Development, Public Works and Housing.  

The energy performance certificate can be issued as a result of an energy audit process conducted with the purpose of selling and buying, of leasing or for the purpose of thermal refurbishment and upgrading of the building. 

Why is the building / apartment Energy Certificate necessary?

The Energy Certificate indicates the energy performance and environment class of a building and gives an energy mark to the building, which provides information to the buyer about the real energy consumption. In other words, it shows how much the utility bills cost per month and how much one needs to spend to get optimum thermal comfort.

The Energy Certificate will help determine the building price more accurately, in that the prices of the houses that have a higher energy mark will go up, since they are cheaper to maintain, unlikely those with low energy efficiency.

What are the energy performance classes according to which the buildings are ranked and the marks are given?

According to the proven energy performance, the buildings are ranked in 7 classes on an energy scale starting from A, which is the lowest energy consumption class to G, which is the highest specific energy consumption. The marks are given from 1 to 100, the mark being determined by well-established criteria; the higher the consumption efficiency, the higher the mark.

The issuing of the energy performance certificate consists in:

  1. evaluating the building energy performance in normal conditions of use;
  2. defining the reference building that is attached to the actual building and evaluating the energy performance thereof;
  3. ranking the building in the energy performance and the environment class.

Following the thermal energy analysis, a thermal and energy analysis report will be drawn up for the building to include: 

  1. the main technical and energy features of that building;
  2. data about how the total annual energy consumption is determined with regard to the heating, ventilation and air conditioning, artificial lighting and preparation of the household hot water, as estimated for that building; 
  3. input data;
  4. calculation summary or denomination of the certified calculation software used;
  5. Conclusions chapter to show the energy information specific to the building, which will be entered in the energy performance certificate, including the energy score given to the building. 

The documents that are necessary for obtaining the energy performance certificate for buildings and plants are:

  1. The building title; 
  2. The document showing the construction year and the construction type;
  3. Cadaster documentation; 
  4. Building location plans; 
  5. Cadaster Plan – showing the building site in relation to the cardinal points and neighbours;
  6. Building plans / scale drawings by storeys;
  7. Drawings of the installations; 
  8. Technical details about the construction material employed, technical details about the thermal and the ventilation equipment and plants, the hot and cold water supply;
  9. Technical structural resistance expert report (if any);
  10. Consumptions in the recent years, monthly electricity, gas, water, sewerage consumption.

During the process for the issuing of the energy performance certificate, the auditor or the audit team must inspect the building. 
The building Energy Performance Certificate is valid for ten years.

Our Team is made up of certified and licensed auditors and offers heat and energy audit services both for individual dwellings and for residential developments, office buildings and business premises. 

Energy Audit is a procedure that serves to identify the main heating and energy features of a building and of the building heating system. After the building thermal audit is conducted, the energy audit analyzes the results achieved and finds efficient solutions both in technical and financial terms in order to renovate and upgrade the building and the relevant plants thereof for increased heating efficiency. 

Such solutions, as well as a number of other recommendations on the choice of the best option will be detailed in an energy audit report, which is the key item of the entire audit process. 

In a nutshell, the audit report describes:

  • How the audit was conducted; 
  • The main energy features of the audited building;
  • Proposals for the modernization of the building and of the building plants;  
  • Conclusions and judgments about the most efficient measures to be implemented, particularly in financial terms.

With regard to the presentation of the report, it is always adjusted according to the customer’s request, since it is the customer that makes the final decision about the investment in the building energy upgrading. However, there are a few constant features regarding the presentation of the energy audit report: “irrespective of customer, the report must be drawn up in clear words and easy to construe”.

The documents necessary in order to obtain the building Energy Audit Report

In order to have the energy audit conducted and to obtain the audit report and the Energy Performance Certificate for the audited building, the customer must produce to the auditor all the documentation necessary for the audit report.

However, in case the customer does not have all the documentation related to the building structure, measurements and scale drawings need to be effected.

Therefore, the following documents of the building log book are required:

  1. building site plans;
  2. building structure drawings;
  3. drawings and description of the building installations;
  4. technical data about the construction materials that were employed, about the heating, ventilation and air conditioning system equipment, hot and cold water providers, etc.

As to the consumption incurred by the existing new or old buildings, the following data will be required:

  1. electricity consumption/month for at least one year;
  2. gas consumption/month for at least one year;
  3. cold and hot water consumption/month for at least one year;
  4. sewerage and waste consumption /month for at least one year.

As to the consumption to be incurred by a new building to be erected, the following data will be required:

  1. Information about the equipment and the material to be used for the building installations (can be found in the building permit design and in the basic design engineering according to which the Building Permit is issued and the building is erected).
  2. Description of the electricity, gas, hot and cold water supply systems and sewerage systems of the building (can be found in the building permit design and in the basic design engineering according to which the Building Permit is issued and the building is erected).

The following laws are listed for information purposes.  
It is possible that these laws might have undergone partial or full amendment or cancellation. 

Therefore it is recommendable that, before making any decision with a view to obtaining an energy performance certificate or a thermal upgrading design, the validity of this information should be verified together with an expert, such as a certified energy auditor!

The prices for the audit or the energy certificate services are determined according to the purpose envisaged by the user thereof. 

In narrow terms, the energy certificate of a building or apartment is the result of a finding. Whereas the energy audit involves a larger process that ends up in providing several technical solutions adjusted to the energy class requested by the customer, with a view to increasing the thermal comfort.

Thus, in order to determine the price for the energy audit and/or certificate, the following items will be taken into consideration:

  1. Gross building area (building/apartment);
  2. The information provided by the customer (design, building log book, energy consumptions, etc.). If the technical information requested is not available, measurements and scale drawings will be done, therefore the unit price will increase.
  3. Complexity of the building and of the available technical solutions; 
  4. Delivery term for the work; 
  5. The repeated occurrence of the design; 
  6. Location of the building / apartment.

For information purposes, the prices vary between 1 EUR /sqm and 4 EUR/sqm. Also, the larger the area, the lower the unit price. For special categories of customers: retired, unemployed and applicants in “Prima Casă” programme, a 10 to 30% discount will be applied.
