We build naturally healthy passive houses in Dublin

Passive houses – the perfect mix of energy-efficiency and comfortable, affordable, and ecological living.

What started with a simple idea has now evolved with dedication, hard work and patience, and become a revolution on its way. We are changing the way houses are built and we can help you bring that change in your life.

Passive houses are not just an on-paper concept. They offers real, tangible results. And we bridge the gap between the idea and the reality with our design-build services.

Built with the highest standards of thermal efficiency, passive houses ensure that you have perfect temperature in your house all year round. And the need for oil and gas? That is completely eliminated and your annual savings are bound to rise.


The Technological Aspects of Passive House

The main concept behind passive houses is to reduce the use of active sources of energy, like heating and cooling systems.

Owners of passive houses get the benefit of using energy sources like sunlight, ventilation, etc. and the temperature of their house is maintained at a level that is deemed ‘comfortable’ all year round.

The strategy that we use is to utilize the “free” heat to keep the temperature of the structure regulated.

So, where does this “free heat” come from? And what is a passive house design?

Let us answer these questions one by one.

Free heat is the heat generated from electrical and gas appliances. Refrigerators, computers, ovens, and even light bulbs give out free heat.

Now, passive houses are designed such that this free heat does not get out of the house unintentionally.

The components that are at the base of a passive house design include is the mechanical ventilation system. This system has an air to air recovery component and is installed to bring in the fresh air and remove the equivalent amount of stale air simultaneously.

The stale air that is leaving the house carries with it the free heat. The heat recovery ventilator captures this heat and transfers it to the fresh incoming air.

This way the cool fresh air enters the home with the free heat and is warm.

Benefits of Building a Passive House

Passive houses are a relatively new concept. You don’t often come across people living in a passive house, right? So, why should you consider building a passive house? Well, we as Passive House Dublin consultants and builders have not one but many reasons to offer.


Your house will become your home only when it offers you complete comfort. Passive houses score extremely high when it comes to their comfort quotient. During both, the cool and the warm months, passive houses offer extreme comfort of living. And we are not the only ones who preach this. Passive house dwellers have testified in favor of this time and again.

Quality of Life

Passive houses not only contribute to the global good, but also contribute towards keeping your quality of life high. One of the principles behind the success of passive houses is “thermal bridge free design”. Through this design we eliminate weak spots, cold corners, and excessive heat loss. Thus, increasing the quality of living. We also help prevent damage by reducing the chances of moisture build-up to a minimum.

Sustainable and Ecological

When passive houses reduce the use of energy and stay energy-efficient, this means that the use of the sources of energy is significantly cut down. This, in turn, lowers the ecological dis-balance and helps you live sustainably, leaving enough for the generations to come.


Passive houses offer two-fold affordability. They do not just help you save a lot on energy bills in the long run, but are also an affordable investment, to begin with. We can renovate and modify old dwelling with the use of passive house building materials or build a passive house from scratch for you.
