The energy saving with fixtures that are able to guarantee the optimal conditions of lighting and thermal insulation is considerable, so much so that those who decide to replace the fixtures in favor of one energy requalification of the building has the right to incentives that reimburse (in terms of tax deductions) up to 65 percent of the expenditure incurred.
Who wants to get sensitive energy saving with fixtures will have to choose doors and windows with high thermal insulation so as to be able to reduce heating costs in winter and air conditioning costs in summer. In addition, with the right fixtures (skylights, roof and wall windows), you can save on lighting by taking advantage of natural light even on cloudy days.
The energy saving with fixtures, between optimal lighting and chimney effect
Skylights, roof windows and large windows can reduce the energy consumption associated with artificial lighting to a minimum, plus, if wisely installed, the fixtures can help to save on air conditioning systems. The windows on the façade, combined with the roof windows, if placed in the same room, activate the chimney effect, excellent for saving on air conditioning: warm air, lighter, comes out of the roof windows recalling the air fresh from the outside.
The energy saving with fixtures, thermal insulation
When choosing the materials for the construction of our windows, the so-called U factor must be considered. The U factor represents the thermal transmittance which expresses the amount of heat that can pass through a surface element of 1 square meter in the presence of a difference in temperature of one degree between the inside and the outside. In other words, in Factor U it represents the complex of thermal exchanges between the external surface of a wall and the internal one. Plus theU factorof a material is high the less suitable that material will be for construction use, on the contrary, the lower the U value and the greater itsthermal insulation.
When choosing windows, the opportunity given by double-glazed windows must be carefully considered: with a lower U-factor, double-glazed windows do not disperse heat. Always talking about energy saving with fixtures righteous, it is necessary to report the heat-insulating glass, characterized by structures with low thermal conductivity.
The energy saving with fixtures, the incentives
The importance of fixtures in terms of energy saving it is universally recognized, so much so that Italian law provides for tax incentives for their replacement. The condition for using the eco-bonus is that the U thermal transmittance requirements, expressed in terms W / m2K, are respected (the transmittance requirements were defined with the decree of the Minister of Economic Development of 11 March 2008, as amended by decree of 26 January 2010). The tax concessions also concern the replacement of the entrance doors, provided that these are windows that delimit the heated envelope of the building towards the outside or towards unheated rooms and the thermal transmittance indexes required for the replacement are respected. windows including fixtures.
The energy saving with fixtures, the do-it-yourself
For Rsave energy with windows it is possible to continue with a mild requalification do-it-yourself. The first step is to add special seals for doors and windows. The seals aim to eliminate drafts improving the degree of thermal insulation but certainly will not affect the U factor of the materials.
