What are the insulating varnishes: a guide on the technical characteristics and operation

Many companies offer special insulating coatings or additives to be mixed with more conventional paints promising miraculous results in terms of energy savings. They argue that the application of these paints on the walls of the building to ensure a 25% reduction in heating costs and even 40% savings on summer cooling.

To make it more convincing often use words like secret ingredients, nanotechnology and ceramic powders. But is it true? It 'really possible with a simple coat of paint and what is special, earn one or two Class Energy Efficiency?

Thermal insulation for buildings: life cycle of the polyurethane foam

One of the elements that a considerable impact on the evaluations of sustainability of a building is definitely the thermal insulation that can reduce and even halve the running costs of the building itself. In the category of the insulating polyurethane industry has decided to inform the market of qualitative data

and numbers of its environmental impacts. In 2005, the polyurethane panels have obtained a class of eco-efficiency according to the methodology BRE (Building Research Establishment). These studies cover the entire production process characterized by:

What are the smart cities and what Italian towns are closer to the concept

Smart cities, cities of the future, able to face the new challenges such as globalization, the economic crisis and sustainable development, while maintaining the high quality of the environment and mobility, with an eye to social cohesion, technology, creativity and the freedom of its inhabitants.

The model also want to strive Italian cities, although the territory is extremely diverse and makes it almost impossible to fit a schema and a standard model of smart city in all its urban realities, as is the case with success for other European and overseas.

The law provides for the protection of buildings against noise pollution

The environment around us, especially the home, some situations that are detrimental to our health seem more obvious than others. In reality, not all forms of pollution effects "immediately" undetectable. Noise pollution is one of these.

In homes, especially in condominiums citizens, forced cohabitation of so many people gives rise to numerous household noises that may be intolerable and that often lead to numerous quarrels. However, the noise sources can also be located outside the building (traffic, transport, industrial facilities, road works, construction).

Expected compulsory insurance property for earthquakes and floods

Compulsory insurance for extreme weather events and construction ban in areas with very high landslide risk also needs to be updated every four years the scientific report on the risks of climate change and must also be updated to 2013 plans hydrogeological structure of river-basin district, forthcoming constitution: these are some of the measures contained in the draft strategic lines for the protection of the territory that the environment minister, Corrado Clini, sent to the Interministerial Committee for Economic Planning (CIPE).

According to the Minister for the plan to protect the territory it takes about 40 billion for fifteen years. As announced by the Minister Clini, the insurance will be required to cover the risks associated with extreme weather events, goods and facilities of both the State and the private sector will be mandatory only for homes and buildings in high-risk areas.

News 2012 tax building deduction

From 1 January 2012, the tax deduction of 36% on building renovations no longer maturity.

The facility, introduced since 1998 and extended several times, was made permanent by Decree-Law n. 201/2011 (Article 4) which provided for its inclusion among expenses deductible for income tax.

It is also the deduction regime relating to restructuring, of entire buildings, performed by construction companies or property renovation and building societies, which shall, within six months from the date of completion of the work, the subsequent sale or assignment of the property .

Documentation building: energy efficiency, acoustic and thermal

Among certifications existing or new arrival. Documentation that indicates the energy efficiency, acoustic and thermal playing most of the opportunity to re-launch the construction market. The energy performance certificate is an official document, valid for 10 years, produced by a person accredited as "energy certification" and several recognized organizations at the local and regional level, issued by qualified technicians who can attest to the consumption and energy characteristics of a building. With what objectives was introduced in Italy this procedure? In addition to work in the interests of saving resources and respect for the environment, inform the owners of the properties on the energy consumption of a building, making them aware of the costs of its management, means increasing demand for energy-efficient homes, what which has a positive impact on the development and revitalization of the construction industry.

Thermal and acoustic insulation of buildings: the cork as a natural alternative

Its most common use is as a stopper for bottles, but the cork is a resource from which come to life hundreds of products. The material resulting from the cork, in fact, is used in clothing, in the footwear industry, the nautical, crafts, furniture and even in bio-building and bio in the traditional one. About its many properties. And 'fire resistant, waterproof, lightweight, protects the environment from the heat and cold, is renewable, biodegradable and recyclable.

From cork waste we produce panels of the caps and granules for thermal and acoustic insulation to be applied to the entire building envelope to improve energy efficiency and ensure the comfort of living: sottotegole and attics, crawlspaces, under floor, walls, insulation to coat inside and outside of buildings. In addition to the high performance resulting from natural material, the panels are made with minimal quantities of adhesives without health risks, typically the same ones used for the production of stoppers.

Approach to the basic criteria for a correct design of efficient buildings

Several times, for some time, we tried to find an adequate answer about the modus operandi needed to make buildings energy efficient, emphasizing at the same time as it was fundamental to resort to a rigorous approach aimed at pursuing high quality standards. Therefore, there is no doubt that, with the proper planning, should be followed by an equally correct execution, without forgetting the important role of the "control" of the two phases that, in doing so, are placed in close relationship and synergy.

It follows that the first important step is to think, in the design phase to a building envelope that takes into account various aspects such as for example: the correct orientation of the building within the lot, or the search for the best ratio S / V, or finally the achievement of greater compactness possible. The orientation of the building, in fact, plays an important role in both the winter and summer behavior. Specifically, with regard to the behavior winter, you can get the appreciable heat gains, while relatively to summer, you should avoid excessive exposure to sunlight of the facades.

Consumption reduction by upgrading the energy efficiency of buildings

Italy counts on its territory 13 million and a half of which produced about 12 million intended for housing. Almost 65% of these buildings are single-family homes and villas or else large and small apartment buildings.

Since the end of World War II to the early '80s was built 50% of the national building stock.

Among them, the buildings built between the '50s and the '70s have very low energy performance, consume about 160 kilowatt-hours per square meter, compared with 75 of a new building.
