ABSTRACT This project deals with design of low-energy family house in Vrcov in the Czech Republic, in terms of The Czech off-grid house (Český ostrovní dům 2017) event for architecture students from the Czech Republic. The concept goes by principles of off-grid houses, while keeping all comfort for inhabitants such as standard grid-on house. The design connects progressive, sophisticated and fully functional solution to achieve the most self-sufficient and economical house. The house is designed for family with four members (parents and two children) and is composed into two floors. The design responds to stakeholder´s way of life and fulfils his wishes and requests. The house is also divided into two parts because of stakeholder´s work. Sometimes he would like to work from home, so the working space is separated from the residential space and so is the mass of both parts. This separation allows the owner to work in the working space without intruding the privacy in the residential space. This part of the house is also fully equipped for living, so it´s possible to use it as a room for guests. To sum up, this solution is designed according to modern way of living in the countryside, using pieces of knowledge of sustainable design and responding to the context of the place and supply inhabitants with all comfort in living close to nature.

VILLAGE, POND, ACTIVITY
IN SITU FINDINGS: Spectacular views into the nature (forests, fields). Close contact with nature – great garden. Connection with people and with the village green– do not isolate yourself. Merging with the place – two floors, pitched roof, nonorganic shape of the mass… Usage of local materials and technology. The high grown tree – especially for children to play. Transport noise – “hide yourself” Calmness towards the nature. Optimal orientation to global sides.

SHEEP “THE LAWNMOWER” Breeding sheep is also part of the design including small stable for sheep. Sheep would be used for mowing the garden instead of standard lawnmower. The energy consumption of lawnmower could be saved – electricity or oil. Calculation told us that we would need for this land (approximately 1500 square meters) six sheep to keep the grass mowed.
SHEEP “THE LAWNMOWER” | 9
IDEA The shape of the building is based on the basic idea that allows the passage between the individual parts of the building, the garden and the access road. This “junction” is a glazed part connecting the main, two-storey (first floor + attic) mass of the object with a second, partly two-storey mass in which is located shelter for a car, garage, shed / workshop, sheep stable and in the 2nd floor above the garage is working space / guest room. These two masses are perpendicular to each other to the shape of letter L. The main mass of the building, together with the connecting neck and the two-storey part with the garage and the working space / guest room, is roofed with a pitched roof. The shape of the main mass reflects several principles. With its “shifting”, the terrace at this place and the children’s treehouse, the mass reacts to the high grown tree, which is located in the north side of the land and it offers children to play. Reaction to the south side with views into the garden, landscape and the direct contact with nature is a porch with a large terrace, large windows and a dorm at the 2nd floor. The design process of layouts, taking account of the orientation and the location of the house on the land, reflected into the resulting mass, size of the window and door openings and the principle function of the entire building. The basic principle of the shape, orthogonality, two storey (1st floor + attic) and pitched roof is based on the effort to adapt to the surroundings and fit into the local environment. This basic principle is supplemented and adapted according to the specific conditions, shaped according to the form, using modern materials, construction and the most energy-efficient technologies. This combination resulted in the final shape, design, material and technological solution.

LAYOUT DESIGN Designed family house is two-storey, specifically it is a ground floor with a residential attic. The total mass is L-shaped, with one part forming the main mass of the house and the other part, perpendicular to the first one, forming complementary spaces, working space / guest room, garage, workshop and a stable for sheep. The location of individual rooms evolves from the orientation to the global sides, the orientation towards the access road and the garden, the views, the direct contact with nature and the funkcionality (for example from the point of view of the distribution of pipelines of technologies), etc. The entrance is placed in a glazed connecting neck (leeward), which forms a crossroad. It allows to go from the entrance directly to the garden, into the main mass of the house, to guest rooms or into the garage. The garage also has indoor and outdoor access to the garden. The garden is accessible from the house by this glazed section or directly from the living room through the terrace to the porch. Behind the entrance door of the main part of the building, there is an entrance hall with a storage space, a utility room and a toilet. Via wide sliding door, we can continue into the living room with a dining room and a kitchen. Here is a staircase leading to the attic. In the attic there is a private room, a bedroom with a cloakroom and space for storage of seasonal items and necessary equipment, children’s rooms, a bathroom and a separate toilet. The design of the attic has taken into account the impressive view of the nearby nature, so there is a relax zone with a large window, which provides the space for relaxation, a library and comfortable chair. The corridor thus becomes a place of residence. Direct access from the corridor to the working space / guest room is possible through the glazed connecting part. The second part of the L-shaped mass forms shelter for a car, a follow-up garage and working space / guest room over the garage. Because of this, it is possible to invite clients / co-workers to the office without having to pass through the residential part of the house and disturbing family life. Following the garage there is designed a workshop, also serving as a garden warehouse for seasonal furniture and tools storage. This part ends with a small stable for a few sheep replacing the lawnmower, which is profitable on this large land. The separation of guest room from the main house, serving as a working space as well, is profitable for several reasons. The couple, entrepreneurs, have space for potential clients or undisturbed work, so the client does not have to pass through the residential part of the house and interfere with family life. If this part of the object is just serving as a guest room, it can be rented (in case of long-term non-use for business). This space includes a private bathroom, a storage space, a kitchen with basic appliances, a desk and a sofa bed. It is assumed that the use of this place is irregular, so there is no need to heat the space if it is not in use for a long period of time, which can lead to energy savings. An important aspect is the connection with the environment and nature. This is why the living room is accessible from both sides. In the south side it is accessible over the terrace with a summer kitchen and seating, covered by a roof overhang against bad weather conditions, and to the north side on the terrace which provides access to a treehouse for children. Thus, the owner of the house can see the children playing on the terrace or around the tree, and also have an overview of the events in the village, towards the pond and the village green. M1:100 0

ARCHITECTURAL DESIGN The architecture of the house is based on the idea and basic principles of the design. The combination of the local architecture character with the modern way of design, materials and sustainable technologies has resulted in this proposal. This is the current form of family housing in the countryside, which does not interfere with the local character of the building and at the same time enables a modern comfortable living, in close contact with nature and people from the village. The proposed house is based on the location, exact location on the land, orientation to the global sides, layout, emphasis on contact with nature, investor’s requirements and his way of life (for example, separating a working space / guest room from the main building to enable the owner, the businessman, to work from home, but not combining work and family life at the same time). Design offers close contact with nature with its openness to the garden and adjacent natural landscapes, as well as connection with the high grown tree and its use for the treehouse for children. By choosing the saddle roof, the non-organic shape and the two-storeyed (1st floor + attic), the house succeeds in incorporating the existing building without disturbing local architecture character. The choice and combination of materials promotes purity and harmony with nature.

NOVATOP is a comprehensive building system of large format components made of crosslaminated solid wood (CLT – cross-laminated timber). NOVATOP components are manufactured from dried spruce slats put together in layers; the layers form an angle of 90˚. The number of layers can differ and determines the final thickness of the panel. The wood is dried to a moisture content of about 8%; this ensures high stability of components and prevents them from cracking. The slats are glued to each other on all faces in the production process. Polyurethane adhesives are used as approved in accordance with European standards for the manufacture of wooden load-bearing building components both for interior and exterior. All panels are distinguished by their high strength, stability and outstanding static load-carrying capacity – they create a solid, secure and true all-wood construction. Due to our exact drying process and our panel forming technology, they exhibit dimensional stability even with changes in humidity. What can NOVATOP components do? NOVATOP System properties allow innovative and exciting design solutions and are an inspiration and challenge for Architects. Due to the solid nature of the NOVATOP system, many professionals are now using wood in situations they may not have previously considered. The technological advancement of NOVATOP eliminates mistakes of common wooden buildings and therefore significantly improves the quality of the finished buildings. The simplicity of execution of structural details, the minimum number of assembly joints and the simple composition of walls comprise a significantly positive argument. The simplicity of execution is reflected not only in the speed of construction, but also makes the whole building particularly economic and cost-effective. Energy-efficient and Passive buildings NOVATOP has been offering a proven and highly efficient solution for energyefficient and passive houses since 2009 and is a supporting member of the Passive House Centre Association. The system is suitable not only for family homes and apartment buildings, but also for reconstructions, additions, extensions, etc. It enables partial deliveries of walls or roofs as well as a comprehensive solution for the whole building. The beauty of natural wood The icing on the cake with this technology is the ability to keep the exposed bearing structure as a final solution of internal surfaces. Visible-quality wood offers completely new possibilities in shaping interior design providing an elegant mix of large areas of wood and other contrasting materials in a modern interior. Despite the increase in demands on project coordination and construction, the result is unique, enduring and cost-effective. A Czech manufacturer, Swiss know-how NOVATOP products are manufactured in the Czech Republic, mainly from Czech coniferous wood, under strict environmental regulations. The production process complies with the strict criteria for a number of certifications (PEFC, Natureplus, ETA…). State-of-the-art CNC equipment using CAD data is used for processing the components and the entire production process is controlled digitally. Everything is produced in the Czech Republic however the system was developed and verified in Switzerland. Source: www.novatop-system.cz

WATER APPLICATION SCHEME The primary objective of the water management in the building is its reuse. For the object we designed a sewage treatment plant with flowing into the retention storage tank and overflow into the infiltration elements. Into the retention tank is swept purified wastewater and rainwater, from the roofs of an object, which also passes through some mechanical cleaning filters. The water in the retention tank is primarily intended for the needs of the house (flushing toilet, washing people...), but also for use in the garden. To supply the house with drinking water, we consider the construction of a well and in case of extreme drought and the connection of the building to the public water supply. As part of the small energy saving of hot water, we consider installing a heat exchanger on the outlet of the waste water from the tub, which passes the heat to the parallel cold water supply. For energy savings when pumping water to flush toilet, we designed a storage water tank in the 2nd floor of the building. The precaution is used for the use of electricity at a time of surpluses, to replenish water from the retention tank outside the building into the accumulation tank, from which the water can gravitationally flows into the toilet tanks on both floors. It could be also connected to the washing machine in the 1st floor.

SCHEME OF ENERGY CONSUMPTION IN THE HOME As the main source for the heating we chose the fireplace stoves using pellets with automatic feed by an electric feeder. Fireplace stoves have built-in hot-water heat exchanger, with which is hot water distributed over the distributor-collector into individual circuits of underfloor heating and into a hot water storage tank. The accumulation tank is in period of non-use of the fireplace stoves heated by an electropatron. As a primary electric source of energy is used a small photovoltaic power plant, which at a time of surpluses of solar energy stores the transformed energy into the battery storage or electromobile. In the period of a lack of electricity from a photovoltaic power plant, a connection is established to the public power grid. Electricity distribution system to individual appliances is controlled and monitored by an intelligent system. Intelligent system decides the use of electricity from the photovoltaic power plant or from the grid and switches off unnecessary appliances. Due to irregular use of working space / guest room we designed electric heating and hot water preparation. Heating is considered underfloor with electric mats and hot water preparation by an electric boiler.

House lighting is an essential element for the quality of living. At the same time, it helps to connect the interior with exterior, which was one of our main goals. In the 1st floor we designed an open space that helps sun lighting the space from the south and north. There is a different story on each of the global side and exactly in the interior, they are interconnected. This Daylight Factor study has served us to design shading (preloaded construction) to exclude the sun‘s direct rays, but not to stop the flow of ubiquitous light into the interior. High-quality illumination helps mental well-being and minimizes the need to light up with artificial light.

GRAPHS OF HEAT FLOWS AND THERMAL LOSSES As part of the decision on the thermal and technical properties of the building, we have optimized the building envelope structures. For variants 1 and 2 we have chosen, to insulate the structures, to the recommended values of the thermal transmittance (according to ČSN 73 0540-2:2011). Other variants, 3 and 4, include the design of thermal insulation at the upper limit, recommended values for passive houses. The last two variants, 5 and 6, are designed to meet the lower limit of recommended thermal transmittance values of passive house structures. The variants are combined with the installation of openings with thermal insulating double glazing (variants 1,3 and 5) and triplets with increased solar factor (variants 2,4 and 6). For winning variant number 6, we decided on the best thermal technology properties. This option is already in the category of passive houses. The design of structures with better thermal and technical properties is considered suitable for the low operating costs of the technology in the house.

For calculations of electricity consumption in the house, we have created variants of the use of the building in summer and winter. We can see differences in the distribution of energy consumption on a normal workday and during the weekend. Variants are developed for assumed hourly electricity consumption. The main source for electricity generation is a small photovoltaic power plant, consisting of photovoltaic panels on the roof structure and semipermeable photovoltaic cells, placed on the movable shading.

According to our assumption the total daily electricity consumption is likely to be higher than it would actually be. Also appliances that do not need to be used at the same time on the same day are included, so because of these appliances, the total amount of energy consumption is increased. We also have an intelligent shutdown system that will reduce our electricity consumption. The intelligent system switches off appliances that do not have to be turned on at the same time. However, during the summer, as we can see on the charts, we have some surpluses of solar energy, that we can store in rechargeable batteries, for later use. Another option is to store energy in an electromobile which will be at the time of the greatest surpluses of solar energy connected to a photovoltaic power plant and recharged. With extremely high profits and low power consumption, we can consider heating the storage tank with an electropatron to store energy „in the water“.

MECHANICAL VENTILATION In the main building is designed mechanical ventilation with heat recovery. The ventilation unit was placed in the 2nd floor, into an attic space. All air distribution in the 2nd floor is kept in the attic space. All air distribution in the first floor is led in void space of the ceiling structure. Ventilated air volumes are calculated, to meet minimum hygienic requirements. When switching off mechanical ventilation, the house can be cross-ventilated in the 1st floor or using roof windows. Natural window ventilation was chosen in working space / guest room, because of the irregular use of this space.
