Last weekend, from Friday to Sunday, RoGBC was present at the National Real Estate Fair with a booth used by its partners as exhibition space systems and products for green building. Among partners: Zest Collective, ALUKÖNIGSTAHL, E-MOTION, SIP PANEL TECHNOLOGIES, Studium Green, EfdeN, ECOPACK, Arta Gradinilor, BuildIN, Energinomics. Together we tried to answer the question:

Can I have a green house?

A green home requires as little impact on the environment both in terms of construction, building materials and energy used in its operation. At the moment it is not easy to build a “green” building. This would involve the use of special construction materials, renewable energy or energy very cheap for cooling, lighting and hot water production. Last but not least, a green home architecture is specifically designed for use within the natural advantages of the place in which it is built. Impossible? Certainly not, but most important is to try to minimize the effect it will have on future home environment. And on your budget!

Construction21 and Metropolitan Solutions are organising a new European online contest

Cities and local authorities worldwide have something in common: they have to become so called “Smart cities”. The intensifying trend of urbanisation forces cities to upgrade their existing infrastructure and to completely develop new forms of infrastructure. Therefore city planers, architects, technical experts and decision makers need smart and practicable solutions that are resource efficient, secure, low in emissions and reliable at the same time. Future infrastructural systems have to be intelligent, autonomously and interlinked to insure the provision of rapidly growing urban populations alongside a high quality of life.

Buildings are an important factor in this urban development, and the “Sustainable Urban Building Contest” seeks to address this aspect. With a view to promoting Best Practice solutions, we ask applicants submitting buildings to the contest to showcase

solutions that are already feasible and have been made reality today. For buildings you have already completed, show us:

1. How buildings can be integrated into the infrastructures of the “city of the future”

2. How buildings can make a positive contribution to infrastructures of the “city of the future”

3. How buildings can help improve quality of life in a city

Applications can be submitted online from the 21st of January 2013 until the 22nd of February in 2013.

The voting phase starts at the 25th of February until the 13th of March of 2013.

Read more about the Contest and the rules at .

The winners will be awarded to present their Best Practice Solutions at the Metropolitan Solutions Fair in Hannover (8 – 12 April 2013). Metropolitan Solutions has developed as platform for applications and solutions for cities and megacities, and has grown significantly since its launch in 2011. In April 2012, more than 70 exhibitors showcased their offers on 3,000 square meters. Beginning in 2013 the trade show has more space in Hall 1 and an innovative concept of immersion in the “city of the future”. Instead of the usual exhibition passageways, for example, visitors walk along streets lit with streetlamps. Panoramic wall images display forward-looking products and urban development solutions. Visitors are brought to Hall 1 in electric cars.

The Atilt House – simple architecture, complex concept

SPA INOVATIONS, active supporter of the RoGBC participated in the “Passive House” Competition organized in Bulgaria.

The team that worked on the project was:

  • arh. Bogdan Teodorescu
  • arh. Ionut Tudose
  • arh. Sorin Juverdeanu
  • arh. Octavian Dragomir

We are happy to share with you’re their project:


The first question mark in elaborating the project was: who lives in this house and what will the owner is going to use it for. The needed spaces being already given, our team decided this will be a dwelling house for a maximum four persons. A vegeration area, measuring 10 sqm will host all the systems needed for this house, such as heating, water, air and electricity systems. This part of the house will also be at the semi-basement level, gaining a more clear view of the site, and also phonic isolation, being desired to exclude most of the systems outside of the house. The volume is to be raised following the idea to create an efficient natural resource gathering house. The resources we had in mind are: the sun energy, the rain water and earth’s characteristics for phonic and thermal isolation. Harvesting the sun energy means to create a volume that can make good use of the sun light during the day, using not only photovoltaic panels, but also letting the sun heat the house by using windows and the greenhouse effect. This aspect will be helped by creating a rectangular cutting in the basic volume for better harvesting of the sun light. Shades are to be considered in this aspect, to prevent the overheating. The rain water collecting criteria implies atilt planes and retention systems. The planes are to conduct the water to a desired route, protecting the house from strong winds, winds that can supplement the water quantity on a atilt plane with a retention system. Exploiting the earth’s characteristics concludes to build part of the house under the earth’s level.

Position and Surroundings

            Concluding the architecture and the volume aspects, following at each step the positioning criteria, we decided that the house will be placed on the site with access from the west, green facade on the north, yard access on the east and glass and shades facade on the south. On the northern limit it is desired to place a layer of high vegetation (trees) to create better protection for the the house ant its atilt planes. Also the building will be placed near this limit to benefit from the sun light in the most part of the yard. The western part of the site will benefit from road access and parking lots. The vegetation used for the yard, other than the trees mentioned, is to be mainly low height vegetation, such us grass, shrubs, bushes, groves and climbing vegetation that will be present on the roof, eastern and western facades and in the underground court. The location, in relations with the urban and natural context, represents a big hint for the material usage aspect.


Engaging the question of material usage, the answer came from the location itself. The closest one was the earth found on the site. The earth will be excavated to build the semi-basement floor, to build the plant area, and to create an access for the rest of the yard and the plant area also. Part of this excavated earth it is to be used in the foundation and some at the roof, the choice for this house’s roof, being a green roof. At this point, it must be specified that the choice of the green roof implies also the use of recycled plastics and ceramics in the  roof’s earth layer. This method helps the vegetation layer to gain stability. The type of vegetation used for The next identified material is wood. The site location is in a hill area where wood can be found as a local resource. Wood will be used to build the ground floor and the roof structure. Also from wood can be made a wool wood named heraklith, an efficient insulator and light partitioning material for the interiors. In the local resource category we include also the stone. Stone will be manufactured for the landscape design of the yard. The village being close to Sofia, the capital of Bulgaria, means quick access to the material manufacture industry and low cost transportation. The conclusion of this idea brings us to the rest of the needed materials such as concrete and reinforced concrete, a very durable material, used for the foundation and the semi-basement structure, stonewool insulation, cellulose insulation, made from recycled paper, a great airtight material, metallic elements used for the access boxes and and coatings and elastic membranes for wind and water protection.

Systems and technology

For electircity production, we propose using 20 photovoltaic panels, which can provide 40% of energy requirements of the building. Photovoltaics  is a method of generating electrical power by converting solar radiation into direct current electricity direct current electricity using semiconductors that exhibit  photovoltaic effect. The convertion is static, clean and eco-friendly. To increase production efficiency, we propose placing a surface of water adjacent to the panels to reflect sunlight.  For artificial lighting we plan to use LED lighting bulbs and low-consuming electric fixtures and appliances, reducing the electricity consumption up to 80%.

Heating and hot water will be ensured by a wood pallet stove, placed in the technical area for optimal distribution, and solar collectors.Wood pellets are a type of wood fuel, generally made from compacted sawdust or other wastes from sawmilling and other wood products manufacture. High-efficiency wood pellet stoves and boilers typically offer a combustion efficiencies of over 85%. Emissions such as CO2NOx, SOx and volatile organic compounds from pellet burning equipment are in general very low in comparison to other forms of combustion heating. For summer cooling and ventilation we will use the Air to air exchanger and Ground-to-water heat pump.

The Ground to water Heat pump has extremely high efficiency: 60% of the energy required for heating comes from the natural environment due to factor COP 5 (5 kW of heat energy produced for 1 kW of electricity consumed). The heat pump produces up to 17kW and is combined with a Hydronic radiant floor heating system, a system of metal tubes laid within a floor that carries hot water into specific rooms, dispersing the heat through the floor surface. Hot water is provided with the aid of the heat pump and two solar collectors.

The Atilt House also makes use of rain water cisterns for irrigation of native landscaping and a vegetated roof for efficiently collecting and filtering rain water. Using rainwater for toilet flushing, clothes washing, bathing and showering make the biggest contribution to saving water. This means that the water levels in the rainwater tank will be regularly drawn down, allowing more rainfall to be captured and used.

Natural daylighting is a very important aspect of its design concept. Window positioning play a critical role in passively heating the house. South facing windows along with the curtain wall warm thermal mass walls and floors affectively warming the house on a cold winter day.  After the infrared rays from the sun touch any surface,  these rays are absorbed and converted into long-wave thermal radiation which is incapable of escaping back through the glass. Indoor vegetation represents a natural bio-filter which is a component of the indoor air quality systems and is an element of the sustainable design strategy for the building.
To remove the stale indoor air and replace it with fresh, clean air from outdoors we used an Air-to-Air Exchanger. The  Air-to-air exchanger is an effective system that provides the necesary air change per hour of 0.5 without consuming large amounts of electricity. In addition to providing a consistent supply of fresh air, the Air-to-Air Exchanger can help significantly lower heating costs during the winter by transferring heat from the exhaust air to the fresh air stream. In the summer, it also reduces the load on the air conditioner by lowering the temperature of the fresh outdoor air.

Through implementation of geothermal, photovoltaic, solar hot water, and advanced heat-recovery technologies this home has succeeded in reducing the energy consumption by more than 80% compared to a typical home construction, an annual heating and cooling requirement of 15 kWh/m2/year, an airtight building shell ( 0.5) and a thermal bridge free construction (0.01 W/mK).

Jury’s feedback:

-Very good sustainable design concept;

-Energy: The thoughts about the wood pellets and water reflection of the sun light to  the solar panels are very good;

Ozone Homes has completed the first building with green apartments in the complex Avalon Residence. The block totaling 12 apartments with two and three rooms and is located in northern Bucharest, in Tunari.

Avalon Residence homes are practical, clean and very good in terms of the purchase price and operating costs. Block number 1 is completed, followed in October to be complete in terms of connection to utilities and building annexes: alleys, access, parking and leisure facilities. Ozone Homes has proposed that in early spring to start organizing the site for the second block, for which there is already reservation request.

Homes Ozone Technology used in Avalon Residence, defines a positive development trend in the construction industry, in terms of achieving outstanding energy performance of buildings. It defined the concept of cross-modular-prefabricated with multiple benefits, not only in terms of energy efficiency in buildings, reduction of CO2 emissions reduction of maintenance costs, especially the speed of execution of construction and follow severe stages of production costs, transport, assembly and completion.

Technology provides an external envelope of buildings with the most effective solution currently known insulation in construction. It also improves the useful area of ​​any space, high resistance in case of earthquake or fire, excellent soundproofing qualities. The living quarters are no longer using methane gas and any other fossil fuel, ensuring the exploitation of clean house. Method of manufacture of materials is done using specialized software, which helps reduce costs, prevent waste and decreases time-scales. Over 60% of the materials used are recyclable and reusable, no environmental pollution.

In the preliminary energy audit, building energy scored 100 (maximum that can be granted) and at the energy class A. For heating, the building requires 23.7 kWh / year, which ensures lower maintenance costs, compared a similar building built traditionally up to 60%.

Avalon Residence is a set composed of 3 blocks P+1, with 2 and 3 bedroom apartments (about 40 housing units, with areas between 51 and 74 m) and prices ranging from 42.500 EUR and 63.750 EUR, plus 5 % VAT. All apartments are furnished and equipped kitchen with appliances, fully equipped bathroom, dressing room, parking and access to common facilities: pool, playground, miniature golf, watch. The ground floor apartments have private garden, while the upstairs have balcony.

Avalon Residence,  is a success for the company, is the basis of discussions with a number of local councils, banks have the “legacy” lots of land, investors need to add value to land that they hold for partnerships in the near future. Ozone Homes wants to become an affordable commodity in terms of green homes, extended at the table. “The most difficult part of our pioneering is the process of explaining and popularizing the benefits of purchasing” green products “. Most people want concrete and brick construction, so we have proved that our product is better so if an earthquake or a fire, but also in terms of air quality in homes. ” said Andrew Prelea.

At the press event for the launching of Avalon Residence, September 28th, Andrew Prelea highlighted the advantages of a genuine eco-building with a positive impact in the foreseeing future. At the event also attended Steven Borncamp (President of the Romanian Green Building Council), Prof. Dr. Ing. Emilia-Cerna Mladin (President of the Association for Energetic Auditors for Buildings,Romania) and Zoli Toth, Green Hour Ambassador forRomania, green activist and well-known artist.

  • the whole program is named “Casa Verde” (Green Homes) and the initial budget will be 520 Million RON out of which 400 Million RON is directed to individuals.
  • the financing is 90% of the cost of the project but it can not be more than 25.000 RON
  • the procedure for obtaining the money by individuals seems very simple – the beneficiary should forward a folder that includes very simple to obtain/prepare documents ( ID, property documents and a declaration of his/her willingness to accept the project) to an authorized installer that should accept and validate the project
  • the money will not be directly received by the beneficiary (physical persons) but will be reimbursed to the authorized installer after the project is implemented
  • the list with authorized installers should be available to the public by 20th of December – on the websites of the Authority for Environment Fund and the Ministry of Environment and Sustainable Development
  • the physical persons should be able to receive the subventions starting with the 5th of January 2009
  • the “Green Homes” program is an annual one and it will be developed each year between 5th of January – 5th of December

The program is also available for companies but there the procedure is different (no information yet) and the financing should be around 60% of the cost of the project and not more than 300.000 RON.

In order to find additional information such as…

– what are the criteria for having a project accepted and validated by the authorized installer

– what is the procedure for companies to receive funding

– what is the accepted duration of a project a.s.o

…we will have to wait for the financing guide to be released. We’ll keep you updated of course.
