As architects, thinkers and designers, we are always pushing the bounds of current innovation to build a more sustainable tomorrow in Crete, Greece.

What Exactly is a Passive House?

A Passive House is a building design standard that integrates sustainable development principles and value engineering schemes for better performance from every angle – to manage moisture, thermal transfer, air, and sunlight for exceptionally comfortable, healthy, and super-efficient buildings. It is an energy-efficient comfortablereasonable and ecological construction concept that is efficient with resources, appropriate to its context, affordable to build and operate, and truly delightful to inhabit.

The “classic five” Passive House design principles—continuous insulation, free-thermal bridge design, airtight structure, energy-efficient and high-performance windows and doors, and filtered fresh air with heat and cooling recovery—are joined by the principles of sustainable architecture and biophilic design.

Eco-friendly Buildings

Everything we do is grounded in our purpose to design, build and manage sustainable, eco-friendly and of exceptional quality properties. We strive to make our mark in leaving Crete a better place for future generations by designing, planning and constructing eco-friendly and sustainable residential and commercial buildings.

Through a rigorous site assessment and by integrating engineering with Big Data, our design response is unique – inspired by local insights, financial, environmental and spatial constraints as well as the social and historical distinctions each project presents.

This assures sustainable and aesthetic solutions with lasting value for clients, inhabitants and society.

Typical Passive House Energy Use

Share of Total Energy by End-Use Comparison.

The pie charts illustrate comparisons between a conventional house in Crete, Greece and a passive house in terms of energy usage.  We are assuming that 57% of the total energy consumed by a conventional building is used for heating and cooling.

If the building was a passive house, the total savings would equate to 47% of the total energy consumed by a conventional building.  This equates to a 85% savings in space heating and cooling cost.

How is a Passive House in Crete Built?

Our Passive House approach empowers us to design spaces that matter. A Passive house is built like any other building. Despite the fact that, a passive house is constructed with almost the same materials, methodologies and standards as a non-passive house, it can dramatically slash heating and cooling energy use by as much as 80-90%.

Most of the Passive House design integrates value engineering and biophilic principles to establish an exceptional energy thermal isolation for the building and ensure a healthy, comfortable, and noiseless interior environments, full of clean, filtered fresh air.

Also, a passive house doesn’t have to look like a spacecraft full of solar panels and off-grid equipment. The most significant parameters of passivity can be tailored to fit different styles of buildings from very modern villas to traditional detached houses and from city-centre apartments to historic apartment buildings.

3 Additional Factors of Passive House Cost to Consider.

    1. Passive House = Investment in an asset: The “premium” for a passive house should be around 5-15%. That said, this added expense up front is really an investment made by the project owner and will generate a return on investment (ROI) in the form of energy savings, exceptional performance and reduced maintenance costs over the life of the building.
    2. Reduced operating costs: Passive constructions can use up to 90% less energy than conventional constructions. Because of their attention on energy consumption mitigation and efficiency, passive buildings are ideal for zero energy building (ZEB) design. ZEBs use solar photovoltaics, heat pumps and small wind turbines to generate as much energy as they use. As a result, net energy costs for operation of Net Zero properties should be close to zero.
3. Supplies: Depending on how easy it is to source construction materials, equipment and supplies your Passive House cost will vary.

How Much Expensive is a Passive House Construction in Crete?

It’s hard to give a quick answer to such a complex question. First, understand there are four key factors that affect building cost: (1) Complexity of the design – the more complicated the building design, the more expensive to build, (2) size – No surprise here, the bigger the house, the more it will cost, (3) location – a property near the seaside will cost more than a property located in a village near the White Mountains, and (4) quality of the structural and construction materials.

Generally, the larger the construction, the less its passive elements will impact the budget. A big detached villa will be approximately 10 % percent more expensive to achieve passive house standards. However, it could be much more affordable because of the continuous improvements in construction materials improvements.

Generally speaking, the number that’s usually quoted is that it costs between €1300 to €2,000 per square meter of building in Crete. Given that an average three-bedroom villa in Crete measures around 200 square meters in all, you’re looking at about €260,000 for the full, unfurnished build. That doesn’t include the cost of the land, the cost of extras like a swimming pool and landscape gardening, special off-grid equipment or taxes, which typically amount to around 15% of the total. Factoring them in gives a final ballpark figure of about €390,000 for a Passive House.

Let’s reiterate – that’s an estimation! There are so many variables to think about when it comes to calculating the cost of your new project in Crete that there’s almost no such thing as an accurate ballpark figure. It’s possible to bag land here for under €100.000, but there are also plots worth millions.
