Study K.EN.A.A.K. – Energy Upgrade

Energy efficiency study is the study that analyses and evaluates the energy performance of a building (according to the Energy Performance of Buildings Regulation (KENAK)). For the issue of a building permit for a new or radically renovated building with a total surface area of more than 50 m², the following is required elaboration and submission Energy Efficiency Study to the competent Planning Authority. It is a necessary study for the issuance of a building permit and replaces that of thermal insulation, as it was before the implementation of the new regulation.

According to the new legislation, every building must meet certain energy efficiency requirements. The requirements, as far as the design of the building is concerned, relate to:

  • the thermotechnical characteristics of the shell elements; and
  • the technical characteristics of the electromechanical installations (heating, cooling, air conditioning, ventilation, lighting, hot water).

The design data are entered in special software energy analysis software and calculate the final consumption primary energy. The building, after being compared with a reference building with similar geometrical characteristics, is classified in an energy category, which will be confirmed by energy audit and the issuing of a certificate (PEA).

The Energy Study for businesses (Hotels, Schools, Offices, Medical Centres, etc.) is a complex process and includes,

  • Recording of all energy consumptions of the building such as cooling, heating, heating, heating, lighting, motors, etc.
  • Registration and evaluation based on fuel and space
  • Economic assessment of the existing energy situation of the building by space and fuel
  • Energy simulation based on a target energy model
  • Proposals for saving and energy upgrading of the building accompanied by economical and technical criteria.

Building Permits Building Permits

Our studies department undertakes the issuance of any type of building permit.

  • License Small Small Scale (with a maximum budget of 25.000 €),
  • License building permit
  • Approval building.

A building permit is required for the execution of any building work, which does not fall under small-scale building work and concerns in particular:

  • erection, addition and repair of buildings,
  • demolition structures with exceptions in specific cases,
  • excavations or backfillings greater than plus/minus 0.80 metres, as well as paving, landscaping and landscaping of plots and land for the purpose of building,
  • construction of a swimming pool,
  • a change of use, if there is a change for the worse in the elements of the coverage diagram or in the design loads of the structural design or a change in the mechanical installations as regards their passages from other floors or common areas,
  • construction of retaining walls, as well as walls and fences not covered by the small-scale building works approval,
  • construction of underground tanks,
  • work on the installation of underground, prefabricated liquid and gaseous fuel tanks at service stations,
  • works , with a budget of more than twenty-five thousand (25,000) euros,
  • legalization any work carried out for which a building permit is required.

We’re on it:

  • the collection all approvals (e.g. forestry department, archaeological department, architectural council, etc.),
  • the pension all the studies required to complete the file for the issue of the building permit, as well as
  • from the adoption procedure to the competent building department.

Energy certificates

Energy Performance Certificates, What is an Energy Performance Certificate? Energy Classification

The Energy Performance Certificate or Energy Performance Certificate (P.E.A.) is a document that records and declares the energy consumption of buildings or parts of buildings. The Energy Certificate is issued exclusively by Energy Inspectors, who are certified engineers from the ministry. In order to issue the Energy Certificate there will definitely be a autopsy of the space, in order to carry out the necessary checks and measurements. The issuance of the Energy Certificate of your building, means the ranking of this in one of the energy categories determined by the Ministry of Justice, while at the same time it will include Recommendations of the inspector (non-binding) for the energy upgrade of the building, with the ultimate goal of energy saving.

Energy certificates are required for all buildings, regardless of floor area and use, when the following cases apply:Existing buildings:

  • On Sale or the lease any building larger than 50 m², in accordance with Presidential Decree 100/2010.
  • If you join the programme “Save at Home“, regardless of the size of the building.
  • The lease commercial premises, such as offices, doctors’ surgeries, shops, restaurants, etc. In these cases the owner now needs to submit electronically all the details of the property to the taxisnet system where the contract will be validated. Even in this case, of course, there are some exceptions where the energy certificate is not necessary, such as in ovens, parking lots, dry cleaners, car repair shops, etc.

The PEA is a certificate that measures the energy consumption of the property. That is, the cost of heating, air conditioning and hot water production, in relation to the losses of the construction, perhaps due to age or the materials used. A similar certificate now exists on all electrical appliances which ranks them in relation to the energy they expend to operate.

So you will have noticed that the prices of electrical appliances vary depending on their energy consumption. This means that the less energy it consumes (A+, A++, A+++), the more expensive it is.

The same is true for the residences. Those that are classified in a high energy category have a higher resale value. They also prefer to buy or rent a house with a lower energy consumption

because the tenant will prefer to buy a property for which they will spend less money on heating, air conditioning and hot water production.

The duration of the certificate is 10 years, as defined by the Ministry of Environment and Climate Change (YPEKA) through Presidential Decree 100/2010.During this period, the energy certificate can be used as many times as necessary for the rental or sale of the property. The only case where a new energy certificate may be issued is if the owner makes interventions that will improve the energy efficiency of the building, in which case the new form will reflect the energy upgrade.

The Energy Inspection procedure consists of the following stages:

  • Collection of the necessary data from the interested party, after consultation.
  • Autopsy – on-site data collection – Photography.
  • Processing and evaluation of data using certified software.

Issuance of the PEA.

  • Built after 1983Built before 1983If the dwelling for which you want to issue an Energy Performance Certificate has a building permit after 1983, you will need the following:

Fire protection

Buildings, regardless of their use, are distinguished in terms of fire protection into existing and new buildings.

The cut-off point for this distinction shall be the date start date the date of entry into force of the Regulation. 71/1988 (A’ 32) “Fire Protection Regulation for Buildings”.

Existing buildings are considered to be those whose building permit was issued before the date of entry into force of the above-mentioned Presidential Decree, while new buildings whose building permit was issued after the entry into force of the Π.∆. 71/1988.

The term “fire safety” was synonymous with the expression “safety against fire”, because this was imposed (and justified) by the strict discipline in the “narrow” sense of the words: fire and safety, from which it derives.

With the evolution of science and technology over time, the belief has been developed that ‘safety against fire’ is the purpose of fire safety – a belief that is generally accepted to be correct.

Both fire safety and fire protection are involved in the general human concern for making the right decisions. For the necessary actions (mental, etc.) it is necessary to know the nature of fire, so it was considered appropriate to follow the separation: fire safety fire protection, review of the prevailing views on the categories of fire according to the nature of the fuel.

This examination of fires shall be carried out

  • with criteria that extend to the technological area
  • for teaching purposes, and
  • with reference to the standardisation in force in our country.

The adoption of the above policy is a consequence of the intention to have an easy source of information for those who study the rational operation of fire safety systems in technological, educational or legislative contexts, since the root of the factors responsible for such operation lies in the type of fire.

Passive and Active Fire Protection

The fire protection of buildings is divided into two sub-sectors:

  • at passive fire protection, which ensures the timely and safe safe and secure escape of the public from the building and avoidance of spread of the fire to other premises or buildings
  • at active fire protection, which refers to the means installed in a building that help to timely the early detection of a fire and/or the immediate response before it becomes uncontrollable.

In addition to fire suppression, particular attention is paid to preventive measures of passive and active fire protection depending on the use of a building.

Finally, buildings are classified, depending on their use, into the following categories: Residential buildings, Hotels, Education buildings, Offices, Shops, Shops, Public places, Crafts, Industries, Warehouses, Health and welfare buildings, Correctional buildings, Car parks and Petrol stations.

The fire protection measures that buildings must have are:

  • Permanent Fire Water Supply Network where provided and in buildings with a height of more than 28 metres.
  • Automatic water sprinkler system where required for each building depending on its use.
  • Automatic fire detection system in hazardous areas and where required for each building depending on its use.
  • Automatic full-slope or local application extinguishing system where required.
  • Automatic explosive mixture detection system where required for each building depending on its use.
  • Manual fire alarm system where required.
  • Portable fire extinguishers (dry powder, carbon dioxide, etc.).
  • Auxiliary tools and instruments.
  • Setting up fire protection teams.

Natural Gas

In recent years, natural gas has become more involved in engineering applications. It has a wide range of applications in small and large scale installations such as heating, domestic hot water, cooking, cooling, steam generation, cogeneration, electricity generation and as a fuel for motor vehicles. It is one of the most economical and ecological fuels and as its distribution network is constantly expanding, it can be used in more areas of the country.

The installation of natural gas requires an application study, which is submitted and checked by the competent authority. Upon approval, we are allowed to proceed with the gas installation construction works. Once the work is completed in accordance with the approved study, the installation is inspected by the competent authority and then the gas supply is switched on.

Our company undertakes the design of natural gas installations on all scales, from a stand-alone installation of an apartment or detached house to installations for large building units & industries.

Advantages of natural gas

  • Natural Gas is cheaper: compared to other energy sources, it allows for significant savings in all forms of its use in the domestic sector.
  • Natural Gas presents limited maintenance needs: thanks to its combustion characteristics, proper regular maintenance is sufficient to ensure the perfect functioning of the installations and a longer lifetime of the appliances in use.
  • Natural Gas arrives continuously and is easy to use: it arrives directly to the home and other places of use.
  • The Natural Gas does not require a storage tank : enough with the problems of fuel supply, with the worries and delays of refuelling, with the periodic checks on stocks.
  • The Natural Gas is paid according to the indications on the meter : you only pay for the quantity actually consumed, as recorded by the meter.
  • The Natural Gas is safe : The reliability of modern appliances and the professionalism of the installation technicians guarantee the highest levels of safety.
  • The Natural Gas during combustion : leaves no traces or residues and does not produce sulphur compounds which are one of the major causes of pollution.
  • The Natural Gas is practical : the new type of appliances also allow for special installation solutions, which, especially in the case of renovations, would be difficult to achieve using other fuels.
