Passive Houses (or Passivhaus) are energy-efficient, ecological constructions known for being extremely comfortable for their inhabitants

Passive Houses are environmentally responsive homes. Their energy-efficient design reduces the ecological footprint to a minimum. In Casal Mallorquí, we use the Passive House model to align with our values for a sustainable lifestyle while respecting our environment.

Thanks to the construction systems we use, we can achieve the highest energy efficiency and comfort. This is largely due to the type of insulation, its density and continuity throughout the enclosure. It is also essential to detect bridges or thermal leaks in the project phase and, subsequently, minimise them according to construction details.

The mechanical ventilation system in Passive Houses are also a key factor in maintaining the right temperature throughout all seasons. It also creates a source of fresh, pure air inside the home. This system, combined with the use of natural energy sources such as sunlight, reduces energy consumption to a minimum, making the need for additional energy practically non-existent.

Last but not least, we must consider the natural and higher quality materials used when constructing these types of buildings if compared to traditional homes.

If you are looking to adapt your home to its natural environment whilst living in a healthy, sustainable and comfortable space, Passive Houses are the best option.

The way in which Passive Houses are built considers the compactness, orientation and solar protection of the building.
The facades are designed with large openings to absorb sunlight and collect heat all year round. Eaves, pergolas, porches and slats are used to protect these openings from direct sunlight, keeping the house cool in the summertime.
The construction contains a continuous envelope that minimises the hot spots where thermal leaks can occur. When constructing a Passive House, great care is taken to ensure all parts are fully-sealed, achieving therefore, the highest energy efficiency.

The windows and doors in Passive Houses are strategically placed to make the most of them. They are double or even triple glazed which, together with this precise alignment, enables Passive Houses to use optimal solar radiation when closed and natural ventilation when open. In winter, solar radiation passes through and heats the interior, while in summer it is blocked to prevent overheating. All this is done to ensure a natural and pleasant indoor climate all year round.

A thermal bridge is a point at which the insulation surface in a building envelope breaks. This can cause heat to escape during winter or enter the house in the summertime. It can also cause problems such as condensation, damp or mould. When building a Passive House, the design is done with great care to ensure all sections are fully sealed, achieving optimum energy efficiency.

Mechanical air renewal systems are an excellent solution to ensure inhabitants health and energy efficiency. Mechanical ventilation secures constant air renewal, achieving the best indoor air quality by reducing the presence of pollen, dust, mites and other harmful particles. The way it works is simple: it brings in air from outside, purifies it and before returning it back outside it keeps up to 90% of its heat to temper the new air that enters. Except in summer, when the system works in the opposite way. This reduces the need for air conditioning and achieves greater energy efficiency.

Thanks to the quality and thickness of the insulation used, energy loss through facades, enclosures, floors and roofs is minimal. In a Passive House, the insulation is continuous and covers the entire thermal envelope of the building. All the conflictive points susceptible to air filtration are protected with different thermal solutions and specialised materials.

What are the advantages of Passive Houses?

As we become more aware of climate change, we have to address not only how we live but also where we live. Passive Houses are completely eco-friendly. They use a small amount of energy to create minimal environmental impact.

Passive Houses offer an alternative way of living which improves the health of their inhabitants, as well as that of the planet. The sustainable, energy-efficient construction significantly reduces CO2 emissions.

At Casal Mallorquí we are experts in Passive Houses. Our commitment to the environment goes beyond words. Thus, we advocate for this model which is beneficial to the planet and its inhabitants.

Passive Houses offer a double advantage: consumption and environmental impact are lower than your standard home. Therefore, we obtain an economic benefit and contribute to a more responsible lifestyle towards the world around us.

The insulation quality helps to keep such high energy efficiency as it allows the temperature to be maintained more easily. Besides, it also prevents noise pollution. Its mechanical ventilation system replaces the traditional heating and air conditioning systems, obtaining a greater control of the temperature than in a traditional house. In addition, its minimalist design adapts perfectly to the different types of construction.

Passive Houses offer an alternative way of living which improves the health of its inhabitants as well as the planet due to the energy-efficiency construction which reduces CO2 emissions.

  • What are Passive Houses made of?

    Passive House buildings are often made from similar materials to those used in standard homes, even though materials of natural origin such as wood predominate. Our constructions have a wooden structural envelope, adding warmth to the design and creating a welcoming home that favours the well-being of its owners. Thanks to this, the execution time is reduced by half. We cannot forget that wood is a 100% renewable and sustainable material, so it is fundamental in the path towards reducing our ecological footprint.

  • Are Passive Houses healthy?

    Yes, they are healthier than traditional houses. Due to the mechanical ventilation system that purifies the air, many harmful particles are removed. Thus, the quality of life of residents is greatly improved.

  • How do Passive Houses keep their temperature?

    In Passive Houses the main sources of heat energy are natural, such as the sun and body heat itself. Factors such as materials and thickness of the walls or the insulation of windows, floor and ceiling, contribute to maintain a constant temperature, preventing heat leaks from the interior to the exterior in winter or vice versa in summer.

  • Do Passive Houses need air conditioning?

    Mechanical ventilation replaces the noisy, bulky traditional air conditioning systems. Passive Houses are also perfectly insulated and the distribution of windows and doors is studied in detail to avoid the need for air conditioning.
