e4 Single-family house in Romania

A single family house in harmony with the people living inside and with the environment outside

The e4 brick house built near Bucharest, Romania is a single family house reflecting the four principles: energy, economy, ecology and emotion. The solution adopted for this house combines the use of clay blocks with the use of alternative energy sources in order to ensure the quality of living with affordable construction and maintenance costs.
Keeping in mind the comfort needed for a modern family with two children, the architect created flowing indoor spaces and set minimal accents by unusual colors and surfaces of natural materials.

Clay bricks as foundation for an up to date family house

The brick walls are creating a balanced indoor climate and ensure protection against sudden temperature changes. Besides that, this e4 brick house reflects the owner’s openness to use sustainable solutions when building their house: from the water heat pump to the solar panels on the roof. The house has a “central brain” incorporating latest technologies that allow owners to control all the parameters important for their comfort and optimum management of the maintenance costs.

Sustainable architecture: The Thermodynamic solar wall

An additional distinctive element, used for the first time in Romania for a family house, is the thermodynamic solar wall (also called "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 greenhouse effect 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 an overall lower energy consumption.

"The e4 concept applied for single family houses represents the ideal vision on a possible house for future. The project explores simultaneously multiple ways for low energy and materials consumption during building process and after that, when actually living in the house.” Dr. Architect Sergiu C. Petrea, Tecto Arhitectura.
