Building's energy class

Ballan info

Energy saving and eco-sustainability are finally the new key words in Italian construction. Bear this in mind, because now all properties for sale must be accompanied by an energy performance certificate, with the relative letter indicating the class from A to G. Purchasers will find this an important factor when considering the costs of property management.

Why is the energy performance certificate so important?
The main difference between a building certified as energy class A and one, for example, in class F (the national average of Italian buildings) lies in the consumption of energy or fuel for heating in the winter season. A class A building requires less than 30 Kwh per square metre per year, equivalent to less than 3 litres of heating fuel per square metre, per year. Vice versa, a class F building requires more than 160 Kwh, equal to over 16 litres of heating fuel, per square metre, per year. It is obvious that the closer the energy class letter is to A, the less it costs to heat the building. And the less it pollutes the environment with CO2 emissions.

A guarantee for those buying or renting a home
Energy certification of buildings is an assessment procedure envisaged by the European directives 2002/91/EC and 2006/32/EC. The declared aim of this standard is to reduce collective energy consumption, lower CO2 emissions, to introduce new draft standards and to improve transparency on the property market, providing property buyers and tenants with objective and transparent information on building characteristics and energy costs.

Lower thermal transmittance, improved insulation
Energy certification of buildings envisages a section on system quality (high energy efficiency) and one for the heat insulation class (low thermal transmittance). But what does "thermal transmittance" mean? In thermodynamic terms, it defines the insulating properties of an element, and more precisely is the physical value that measures the amount of heat exchanged by a material or complex element per unit of surface area and unit of temperature, in which the unit of measurement is W/m2 K. The lower this value, the less heat is dispersed outside during winter while less heat penetrates the building during the summer. This is why less energy is needed to heat or cool a building certified as energy class A, B or C.

The role of the garage door in building insulation
Together with their relative frames, the doors and windows themselves - including garage doors - contribute to the insulation of a building, if they meet the transmittance requirements, which depend on the climatic zone. A garage is often adjacent to or integrated in the home. Although there is no obligation to consider it a heated room, it is worth treating it as such. This prevents a cold zone from “intruding” the home, lowering the energy performance rating. This is the reason why it is worth investing in an insulated garage door, especially when the garage is integrated in the building.

Ballan SpA is a green company, boasting long-standing implementation of policies for environmental protection and energy saving. Ballan is now one of the leading companies in its sector to offer products that meet with the most stringent requirements regarding thermal transmittance for energy upgrading of buildings (certified by tests performed with a notified body). The up-and-over doors Linealegno HF are proof of this commitment, as are the up-and-over doors Fusion HF and sectional doors New Age offering outstanding features such as excellent thermal efficiency.
