Energy efficiency refers to the minimizatio n o f energy co nsumptio n thro ugh design, seeking ways to use inno vative heating and edge building techno lo gies in o rder to beco me a referenced NZEB. Enviro nment. Reductio n o f greenho use gas emissio ns by the use o f enviro nmentally friendly renewable energy so urces such as sun, geo thermal heat o r bio mass. Emo tio n & health. The ho use seeks to achieve that unique quality o f living and explo res ways to ensure a healthy ro o m climate using as much as po ssible the natural building material o f clay pro ducts. Eco no my. Last but no t least, we o btained an affo rdable ho use and maintenance co sts in o rder to pro ve that it is po ssible to have an attractive and affo rdable NZEB. The E4 House concept follows the subsequent development of the major energy efficient building design methods but at the same time pays attention to the cultural background and the regional adaptation of the layout to each context. In architectural terms, the main elements that are crucial to the building’s energy- efficiency are also the most powerful visual characteristics - in particular the components of the buildings envelope. And these elements are also the main factors that bear the marks of tradition and culture, represented by the urban rules and the site context. Based on this, the project focused on the contemporary approach of the pitched roof - covered with ceramic tiles, of the massive brick walls and terraces - possible to have ceramic finishes, of the windows typology and the balance of textures and colours, both for exterior and interior.

Thro ugh in-depth studies o f co ntempo rary architecture, tecto pushes the limits to the mo st inspiring, intriguing and inno vative co ncepts. Go o d architecture do esn`t just fulfill practical needs but exceeds them by captivating the users and engaging their imaginatio n. Tecto green wo rks at the intersectio n between research and practice. We seek to demo nstrate that sustainable materials and techno lo gies have a legitimate and necessary ro le within architecture. They do no t have to be asso ciated with co mpro mising aesthetical values; o n the co ntrary, they can enrich the architecture by creating healthy and dynamic buildings. Tecto `s green co ncept challenges traditio nal thinking by studying, refining and implementing new materials and techno lo gies into pro jects. As part o f o ur sustainable develo pment wo rk, tecto team has been certified passive ho use designer in acco rdance with the passive ho use standards fo rmulated by the german passive ho use institute in darmstadt.

Thus, the so called E4 pro gram - E fo r Energy, Eco no my, Eco lo gy and Emo tio n – was develo ped as a po ssible future ho use mo del. The architectural took into account the localiz ation of building into the site and orientation facing the cardinal points and the predominant wind. These decisions contributed to the shape of the building geometry, as well as to the distribution and properties of transparent and opaque elements of the façades. A major innovative energy system considered in the proposed E4- house design consists in an optimiz ed Trombe wall, known to provide heat by a combination of thermal mass and greenhouse effects. In the original Trombe wall solution, the southern wall of the building – usually made of materials with heat storage properties (thermal mass: bricks, concrete, stones) – is painted in dark colors and has a glass panel placed in front of its surface, at a certain distance to create an air cavity. By greenhouse effect, the wall is heated by convection from the warm upward airflow that is generated through the gap. The present design attempts to optimiz e the Trombe wall by combining its effects with ventilation. The Trombe wall is placed on the Southern surface of the living room, where the overnight temperature may be lower than the temperature needed for comfort during the day. The energy efficiency approach of the architectural design also focused on the building materials. A key element was the use of recyclable/recycled and/or locally available materials. The design team developed a range of performance measures in terms of the building envelope materials, among which the most important are: High levels of thermal insulation, Additional insulation, Use of metal consoles and 15 cm of extruded polystyrene to break the thermal bridges,Use of intelligent adaptive membranes,Use of energy performant triple- glaz ing windows and doors.The passive energy efficiency strategies are however limited in their effects for the NZEB concept. Active measures were added to bring their part in the overall energy performance of the building. This included:Two solar collectors that supply heat to a buffer energy storage unit to partially support domestic hot water preparation, as well as space heating. Twelve photovoltaic solar panels were also mounted in order to produce electricity and reduce the carbon foot- print of the house.Low- temperature heating pipes placed underfloor and radiant wall heating/cooling with built- in tubes. A central home automation technology may enable homeowners to control heat, window coverings, lighting, security sensors and cameras, as well as to track comfort parameters in real time or various energy consumptions over times. Such a system inform and educate the users and may lead to a change that experts call in short format „energy bahavior”.
