We built the foundations for the first low-energy consuming house in Sofia, according to European standards and requirements for energy efficiency with energy passport and protocol tests for density.

The house is semi-detached. Made of wood, stone and natural materials with a total area of 400 sqm. It has two floors. The construction of the house is solid wood, in the section between slabs, stairs, and the roof. The surrounding walls of the house are made of wood and wood materials with insulation alpine technology. The foundation of the house was built by “Lirato Building” LTD. At this stage, the most important thing is to observe all sizes set by the constructor parameters and to perform quality heat and waterproofing of the foundation. The elements of the house are manufactured by Meiberger for 40 days. The house is built on the spot for five weeks by the Austrian team. External and internal frames are the high-quality combinations of aluminum and PVC, the doors are massive veneer manufactured entirely from Josko Windows & Doors, Austria. The outer insulation of the house is heraklit boards covered with treated by a special technology Siberian larch (Class A) in combination with lime-cement mortar. The facade is ventilated, and the floors of the house are all integrated systems – water, sewer, heating, cooling, and ventilation.
The heating and the cooling in a house  are determined by heat pumps water-land by German manufacturer Viessmann Werke, which is connected with four boreholes, each 100 meters deep. The drillings were made in five days by the German company Baugrundsued. The finishing works are completed in two months by Austrian and Bulgarian teams. The house was built with comfort ventilation with fresh air, produced by the German company Wernig. Ventilation provides high-quality air, secured against emissions, allergic and asthmatic diseases independently for each family house. The Solar collectors by Viessmann Werke provide hot water. The roof is made of Austrian company Breitfuss on technology that requires no maintenance in operational period, with a final layer of white pebbles. The entrance to the property is from the east entrance to the house from the north Energy Center (Bramastan), which brings together by a central lobby both houses. The furnishing of the house is from renowned German manufacturer hülsta. The decoration, fabrics, and curtains are the brand by Laura Ashley.

There are four stages in the design and construction of energy efficient building in partnership Meiberger Holzbau and Veda Asset. The first stage: “Individual project for building” starts with filling out a checklist of the manufacturer, the customer determines their needs and desires. After signing the contract manufacturer produces a conceptual architectural design – a description of the architectural design of the house, functionally designed facade views. The approved conceptual design budgeted by the manufacturer. The budget covers plates, interior and exterior walls of the building roof. The budget at this stage includes foundation, installations, finishing, doors and windows, interior. The design was based on the approved preliminary project. It was held at a consultative meeting with the client to specify the terms of reference for the technical project, which includes the notion of client exterior, interior and technical solutions chosen for the engineering part of the project on the implementation of the building. The Technical project covers all parts and it is the basis for the issuance of a building permit and implementation of individual parts. Bulgarian designers in different parts checked for consistency with the Bulgarian standards and countersign. Once the client approves and signs the technical design, Meiberger Hozlbau and Veda Asset produce the full budget of the building in all parts and brought to the attention of the customer offer for the production of building and the terms of the deal with a draft contract.
The second stage in the design and construction of energy efficient building its production. Third stage started in parallel with the second and includes: preparation of detailed offers for other parts of the execution of the building (windows, doors system for controlled ventilation, heating and cooling, water supply and sewerage, kitchen, sanitary, electrical, furniture and decor) and negotiating with the client, according to best practices. At this stage seek opportunities for optimizations to the full budget of the building. The installation of the construction site and the transfer of the finished building the client is the last fourth stage of the design and construction of energy efficient buildings.

Vedic architecture (Sthapatya Veda)
Sthapatya Veda (Stapatya Veda) translated from Sanskrit is one of the 40 areas of knowledge of the scriptures is a complex science to create buildings with cosmic force. This is the oldest and most comprehensive system architecture in harmony living by environmentally-friendly laws.
Compliance with the principles of Vedic architecture provides an opportunity for happiness, healthy and comfortable lifestyle or work in the future building. Vedic architecture is based on a fundamental understanding that the man is a cosmic creature. Human physiology has its precise analogies in space. The Sun, the moon, and other planets have their equivalents in brain physiology and stand together in resonance.
Vedic architecture is defined as the intelligence of the natural laws that harmoniously connects individual life in space. Each technique has its own tools for simple, quickly and efficiently achieve the objectives. Five basic principles of Vedic architecture is the key to quality of life: orientation of the building – positively affect the function of the human brain; provides deep and recovering sleep; brings health and motivation through vital rays of the sun; the rooms in the building – support biorhythms and daily processes of humans in the proper arrangement of individual rooms according to the energy fields of Vedic geometry and specific functions; Energy Center Brahmasthan (bramastan) – strong impact on the occupants of harmonious, charged with energy and vitality, creates an atmosphere of happiness and success; perfect cosmic proportions – provides the full potential of human physiology as the length, width, height and internal spaces are sized according to Vedic math to comply natural and cosmic proportions.
Consultation and design of the future house or building started in the selection of land. Comply optimal location to the cardinal points of the earth and building size, shape and distribution of the built space, slope, location of groundwater and construction of the surrounding area.
