// Description
The challenge of designing an E4 House, coming up with personalised ideas and design to enhance the 4 main
concepts: Energy efficiency, Environment, Emotion &health, Economy.
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.

meaningfulness, receptivness to inno vatio n and aestethic expressio n. 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. This way, we o ffer co mpetent
co nsultancy in design, calculatio n and co nstructio n o f passive ho uses o r buildings with lo w energy co nsumptio n, with healthy
and co mfo rtable indo o r climate all year ro und.
Tecto detail is specialized in design o f co mpo nents and details, in o rder to identify, rethink and refine any element that do esn`t
achieve the highest po ssible architectural quality. Fro m individual detail to o verall systems, o ur aim is to o ptimize fo rm and
structure. We fo cus o n building with appro priate metho ds and sustainable techno lo gies in o rder to have the best po ssible
result, no matter the scale o r functio n.
We stro ngly believe that meaningful, well-so lved details are the o nes that shape an architecture wo rth living in.
De script io n archit e ct urale : The purpo se o f the pro ject is to design an afo rdable single family ho use that best describes

A majo r inno vative energy system co nsidered in the pro po sed E4-ho use design co nsists in an o ptimized Tro mbe wall,
kno wn to pro vide heat by a co mbinatio n o f thermal mass and greenho use effects. In the o riginal Tro mbe wall so lutio n, the
so uthern wall o f the building – usually made o f materials with heat sto rage pro perties (thermal mass: bricks, co ncrete,
sto nes) – is painted in dark co lo rs and has a glass panel placed in fro nt o f its surface, at a certain distance to create an air
cavity. By greenho use effect, the wall is heated by co nvectio n fro m the warm upward airflo w that is generated thro ugh the
gap. The present design attempts to o ptimize the Tro mbe wall by co mbining its effects with ventilatio n. The Tro mbe wall is
placed o n the So uthern surface o f the living ro o m, where the o vernight temperature may be lo wer than the temperature
needed fo r co mfo rt during the day.

E4 starts with the develo pment o f advanced energy co ncepts as a prerequisite fo r 20 10 /31/EU Directive, which asserts that
starting with 20 20 all the new buildings will have ZERO ENERGY BALANCE. 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
