AN ENERGY EFFICIENT HOUSE BUILT WITH CLAY BLOCKS

e4

This single-family home in Romania was built in accordance with the principles of the e4 concept, which focuses on energy, economy, ecology and emotion. The building combines clay blocks and the use of alternative energy sources to create a home that represents sustainable, high-quality, living with affordable construction and low maintenance costs.

AN ENERGY EFFICIENT HOUSE BUILT WITH CLAY BLOCKS

e4

This single-family home in Romania was built in accordance with the principles of the e4 concept, which focuses on energy, economy, ecology and emotion. The building combines clay blocks and the use of alternative energy sources to create a home that represents sustainable, high-quality, living with affordable construction and low maintenance costs.

With this e4 house near Bucharest, Tecto Arhitectura has proven that sustainable building does not have to look dull. As affordable construction was part of the brief, the architects achieved a modern look by using clear and structured forms and the interplay of black and white. This concept has been applied both externally and internally. Keeping in mind the comfort needed for a modern family with two children, the architect created flowing indoor spaces and big windows to let in plenty of daylight.

IN FULL CONTROL OF THE INDOOR CLIMATE

The clay block walls ensure a balanced indoor climate and protect against sudden temperature changes. Furthermore, this e4 brick house reflects the owner’s willingness to use innovative solutions when building their home: from the groundwater heat pump to the solar collectors on the roof. The house has a “central brain” incorporating the latest automated technologies, which allow the owners to control all the parameters affecting their comfort and optimum management of the maintenance costs.

CLAY BLOCKS – SUPPORTING LOWER ENERGY CONSUMPTION
An additional distinctive element is the thermodynamic solar wall – “Trombe wall”. It contributes to the natural ventilation of the house by enhancing heating/cooling of the interior with zero power consumption. This is possible due to a combination of solar power technology and the thermal inertia of clay blocks. In winter, the thermodynamic solar wall absorbs heat during sunlight hours and then slowly releases it overnight, supporting lower energy consumption.
