The Syma Hall 2009th held from February 11 to 13 Roofs, Walls, Building Facades & Energy Exhibition & Conference for 3 days provided a variety of "ground" of construction of the professional participants of discussion and meeting. The overture as a major event (conference, a panel dealing with reconstruction in parallel) was discussed in the green roofs are still many ways to discuss the fate of troubled fed. Alexander's chief architect Fegyverneky welcome words not reflected in the narrow topics, speech is more current news from szemezgetett of construction.

The step-child

The opening of the host Bellavics Laszlo said. The President of the National Association of Builders Green Roof presented the association's history led to his most important moments of their mission and of course also specified. The successes and failures in both rich in the closing decades of the main objectives of the organization still is, to win the right to exist and not just an independent profession of architecture or horticulture stepchild of the count.

The opening for the first impressions I almost started to amplify the insight that there really is something very new to the entrance and false things. This is only and exclusively in the transaction, rather than the quality of presentations presumption. What I mean? It is simply that the artist in its first two foreign languages ​​and translation students were not in sync with professional interpreters, but it sentence by sentence, pausing only managed to solve. This error, however, the amateur organization made ​​us a lot of professional artist, who I think was meaningful to all involved in the day. It is mine, who is just starting to really interested in the subject and it was a challenge at all times pay attention and absorb new knowledge, both of those practitioners who have a real jamboree was an event where the latest results could share with each other professions.

Whose roof gardens are still all new to them and not really able to put their website ZEOSZ attention of the most important information

How to make it more attractive, to encourage green roof construction? Practice in Germany | Ing. Karl-Heinz Braun (Germany)

The German Roof Gardener Association sent as published by Karl-Heinz Braun's introductory lecture, to the roof gardens of some of the disadvantages and advantages of sketching began. The major problem of modern urbanization in the closed surface finishing. A lot of paved surface by rainwater can not elszikkadni, but flowing in increasing quantities on the busy channel system. Not only the natural water management, but also upset the household heat, reckoned to be the development of urban heat islands. They should not suffer to be necessary if green roofs widely introduced. What is the advantage of these lies? The outlet of the green roof as compared to water and heat retention of 50-90% and is also important that the rainfall is not yet transferred to the rains, but also allow further delay of the channel system thus freeing the excessive load. Bind through photosynthesis, carbon dioxide, is cooled by evaporation through the surface and the surrounding air as well. The temperature is also an important balancing role, as measured on the bare roof, sometimes up to 80 ° C temperature of the water seal is an erosion, amortizing.

Today, it is also certain that the growing health risk in cities solid pollutants the plants would be able to bind with high efficiency. This is very important in view that the German cities of temporary traffic restrictions failed to reduce the concentration of fine dust. More livable environment for the realization of green roofs zajszigetelésükön too high, of course, also contribute to their recreational functions. Karl-Heinz Braun, good insulating ability of the energy savings resulting from even a very simple green roof is estimated at 5 liters of heating oil per square meter per year.

The Germans are closer to us than to those perceived to have benefits for part of their everyday practice in the construction of green roofs. On the one hand, the Federal Nature Conservation Act, on the other hand, the grants provide the framework. The law provides that a new building at the old areas in conditions should be ensured that recorded in the vegetation. The roofs of at least 60% of an extensive zöldtetőnek must be in the orchard for at least 10 cm in height and bears live in permanent vegetation. The details of the development authorities.

That this is not just on paper but in reality it is, that the artist has good examples. The "Stuttgart 21" project stations still to be realized, Potzdamer Platz area of Berlin, however, already 10,000 m2, water recirculation system boasts a green roof, which allows 23,000 m3 of potable water per year saving. Such systems are then collected by rainwater, irrigation during dry periods, or even the house gray water needs can be satisfied.

So You'd think that all is well in Germany. This contradicts the fact that in recent times megkurtították direct financial support. Wernau example of the station - where local people are transformed by their own extensive gardens in the gravel roof, however, shows that the German people in some cases, able to act without the incentive for improving the environment.

The German practice is still a "joker" in many cities because of the additional drainage fee shall be paid after the run-off surfaces. This indirect measure, try to shorten the payback time for green roofs, which are so many advantages in economic terms they represent an alternative to the flat roofs in comparison.

Corrosion of insulating plates hydrobiological green roofs | Marek Novotny (Czech Republic)

Mr. Novotny stated at the outset that the Czech Republic is still no law on the establishment of green roofs, and their steep roofs are green realized plane szemezgetett. A special application is seen in a shopping center in Prague at the top, or rather the facade completed extensive roof slope of 58 °. If the slope is such a great emphasis should be placed in the planting medium mechanical recording, the statics and vegetation maintenance as well.

The vízszigetelésnél the root-resistant design is practically a requirement, it is only recently come to light, which is of great importance to the microbial corrosion, that is the phenomenon wherein the vegetable acids, and other emissions due to spurring dynamism microbial activity attacks the insulating plate, such as PVC film. The material for the first time the decay of flooded areas occur in the form of star-shaped cracks and spreads more and more damage to the film. The insulating plates would threaten other hazards such as hail or any mechanical damage during construction. I feel that the presentation made at the end of the specific questions - what is it that is causing the corrosion and what precautions to protect ourselves against it, but we have not received an adequate response.

Green Roofs in the domestic regulatory practice (OTÉK and other legal background) | Bellavics Laszlo

"We boarded the Form 1, but pulled hand brake!" She commented Bellavics's the situation, so that our country has some culture and legal background of the green roof building, but the legislation does not appropriate and the gap is huge.

The artist OTÉK as amended (the green roof components: II. Chapter § 25 and Annex 5) is like a soup bag: small, thin, meaningless, artificial, and not charging the man with satisfaction. Why such a pessimistic ZEOSZ-president who, however, a problem-solving, there are proposals that would like to devote a separate writing.

Organic matter without extensive ültetőközegek | Dr. Laszlo Gerzson

The Corvinus University associate professor of the Faculty of Landscape Architecture lecture highlighted the potential of building a green roof is one of the most professional dilemma is always the right choice means the planting medium. Basic requirements of the planting medium is that it is to be lightweight, inexpensive, structure constant, and sterile, have good water retention and water permeability, and have high nutrient content. Intensive roof gardens to the traditional garden soil to a similar but more stable structure, planting media from the truth. Extensive green roofs and planting medium should be sought in the application that does not provide good living conditions for the unwanted weeds. Not all spontaneous-looking species, however, does compete with the more noble species, in some cases, thriving plant communities are created to increase biodiversity. Germany likes to install Sedum roofs, moss, which is a good pairing, because while the Sedum species in the dry, while the moss-like species in the wet weather.

The planting medium to meet the strict demands, but what kind of materials to comply with these? False assumption that only the soil. The planting medium can be inorganic or organic creators. Body of the artist in the tuff ones, (eg, rhyolite), clay, lava and téglaőrleményt the agyaggranulátumot, the blast furnace slag, perlite, plastic chips, and recycled cotton stone highlighted. Be an integral component of peat, compost and potting soil, or even rice shell, which latter is difficult to obtain because the concrete industry can use this material.

Why is it that the MOM Pak on top of garden greenery just below the air conditioner, very rocky, nutrient-poor periphery strengthened? Remember Liebig's Law? The minimum standards are recognized by states that the plant is always adapted to the environmental factors which are present in the most adverse conditions. The roof is a hot, sunny summer afternoon is not the soil and nutrient deficiencies are very significant, but the heat and lack of water.

Green Roof role in mitigating the urban heat island | John Prekuta

St. Stephen's University assistant professor of tetőkertjein own design (eg in a nursery flat top designed extensive gardens) has shown through how beneficial role of green roofs in the summer heat waves in cushioning. In addition, as described in a previous research, which examined how different surfaces covered roofs of the quality of storm water flows through. It was established that the vegetated surface of the inorganic micropollutants (cadmium, lead, copper, chromium, nickel, zinc) can be filtered against a significant part of the smooth PVC coating.

Extensive and intensive roof garden next to each other

The report, far from being over, the afternoon "A" section will continue with the presentation. Will address climate change, the costs of green roofs, insulation, and various application possibilities of planting a specific media, and that the most frequently asked how to avoid mistakes | VÉRTESY Monika environmental engineer
