The first 100% eco-building

Headquarters organization World Wide Fund for Nature in the Netherlands is the first building in the world with zero carbon emissions.

The building has a natural ventilation system and the outside is covered by solar panels that generate electricity and hot water. The ceiling contains small glass tubes which allow circulation of water providing heating during winter and răcorirea during the summer.

All materials used were first verified to not negatively impact the environment. Thomas Rau, chief architect of this project presented the main points for the WWF headquarters is 100% organic:

"First class does not use fuel at all. We use what we have. Keep the heat emitted by humans and machine. Cooling system is based on the water which then use the toilets. Recover heat from exhaust air before him. Deposit heat into the ground. Regenerated by solar energy networks, etc.. "

More over, the building has a generator for heat and electricity for emergency operating on oil in the first system of its kind in the world, says Thomas Rau.

Headquarters is a friendly environment and animals. Thus, the roof allows the birds to build nests, and the basement is a welcoming environment for bats.

Passive House Energy Independence

Passive house concept and the European trend A "passive house is a dwelling without heating system, heat is supplied by the ventilation system of housing.

A passive house standard outer jacket contains a highly insulated thermal windows thermo wood joinery and a ventilation system integrated which eliminates foul air in the building and it passes through a heat exchanger which recovers part of the heat transferring a the fresh air coming out of the housing.

A passive house can be built anywhere in the world because the concept is very simple but at the same time, intelligent. According to Passivhaus Institut in Germany there are several thousand passive houses built in Europe, especially Germany (3500), Austria (1000), Switzerland and Sweden.

What is a passive?

A "passive house is a dwelling in a separate heating system almost is not necessary or not necessary at all. Heat is provided by a special ventilation system, mounted in the housing. A passive house offers very comfortable living and healthy, both winter and summer. In a passive house is missing quite damp and cool summer in the interior is very nice. Those who suffer from various allergies (currently, dust, asthma, etc..) Can smoothly keep windows closed in spring or autumn, because housing is fed with filtered air prosperous.

A passive house standard outer jacket contains a very good insulator (usually less than 20 cm of expanded polystyrene of high density 30kg/mc), carpentry wood windows (or PVC) with double glazing windows thermo Lowe of 3 sheets and a system of integrated ventilation, which eliminates foul air in the building and it passes through a heat exchanger which recovers part of the heat transferring to a fresh air coming out of the housing.

In conclusion, passive house is defined by two basic elements: a jacket of the building very well heat and lack of heating. May be true that a home built in passive Romania requires no heating system? According to calculations made by Passivhaus Institute passive house needs only 10-15 kWh/m2 per year, equivalent to a maximum 1.5 cubic meters of natural gas or 1.5 gallons of fuel oil per 1 sqm of surface heating on the year.

For a standard housing, these figures are at least eight times higher. As mentioned above, the second element of a home is the lack of a passive heating system classic, being replaced by a simple but intelligent ventilation, whose costs do not rise much above the cost of heating a modern classic.

A passive house is always equipped with a mechanical ventilation system very effectively to maintain optimal air quality in housing, record without significant loss of heat. Thus we get much lower loss of energy when ventilated house (less warm air outwards) and more interior comfort (less cold air entering the house).

For most of the year that lead to maintaining a constant temperature inside delightful house, without the need for a heating plant. During winters with extreme low temperatures (-350C) requires an active heating (electric oil heater, etc.).

But one faorte little power so even in conditions of extreme minimum temperatures in passive house temperature will comfortable one. Usually, the investment used to implement an effective classical heating in a dwelling classic will be used for better thermal insulation and sealing of windows, and better ventilation of the passive house.

Conclusion German and Austrian specialists is that a passive house does not need installation of heating, but only a very good thermal insulation and a ventilation system with heat exchanger.

Green buildings, in 2019 binding

Since 2019, all newly constructed buildings in the European Union should produce the same amount of energy that you consume. Parliament voted to end last week as the deadline for achieving this goal should be 2019. For public buildings, the term is established in 2016.

"The potential of buildings to consume less energy and produce renewable energy is huge," said Arianna Vitali Roscini, responsible for European Policy of the World Wide Fund. "Promoting energy efficiency is an extremely beneficial for Europe. By implementing energy efficiency measures to improve energy security, reduce emissions, encouraging technological development and creating new jobs ", and showed Vitali Roscini. A quarter of the buildings date from the first half of the twentieth century Voting has revised previous legislation regarding energy efficiency of buildings. New energy efficiency standards will apply to all buildings refurbished, not only those with over 1,000 square meters, as the previous law provided. This is important because a large part of the European building stock is the existing buildings, of which 25% were built before 1945. In Europe, energy consumption of buildings is 40% of the total, of which 36% is energy-producing emissions. Much of this energy can be saved through insulation, heating and cooling best with double windows, lighting or economically smart meters to monitor energy consumption.

Tax Relief....scutiri de taxe...

In Romania, tourist establishments that have a capacity of housing up to 40 cameras and services environment would be exempt from tax on income or profits for a period of 10 years, stated in a bill submitted to the Chamber Members.It provides reduced rate of TVA to 9% for the same unit of accommodation.
To receive a green label, operators must meet three criteria from a total of six. These included the use of alternative energy, eco-bulbs in the tourist location, the use of ecological detergents, but also the promotion of Romanian traditional environment.

In Romania, the only Eco Hotel is located in the resort Saturn.
