Troni-Brien House is a single family project with particular clients which were looking to live in a Zero Energy House, therefore the right standard to design with was Passivhaus. In Chile, normal housing heating demands about 150 to 200 kWh/m2. With Passivhaus requirements this house demands 15kWh/m2 per year.
Troni House is located in the mountain range of Santiago, Chile called Farellones. It‘s a rural area 1350 mamsl with a climate of warm summers and cold winters, with snow and temperatures below 0°C.
The building is facing north with large windows to enjoy the view and solar gains in winter, protected by eaves which provide shade and prevent overheating in summer.
he design phasestarted in 2012, the construction process started in November 2013 and thehouse was completed by April 2015.
The Project development and construction process haveconstantly encountered challenges. The construction cost was an importantissue, in Chile there is only one Passivhaus certified project so theconstruction technical requirements are far from standard, and the site difficult access increased the problem. Including all systems the construction of the project is around 40% more expensive than a traditional house in Chile.
In order to ease the materials transport to the site,the project was designed with light weight SIP panels, and an additionalinternal steel structure was needed for seismic requirements.
The construction materials and systems were mostly covered by imported products available in Chile, only sealing air tight products were brought from Germany.

Building users opinion
The house is performing completely within expectations and we are extremely grateful to all of you for the way in which you have contributed to realize a pioneer house in Chile in terms of sustainability and energy use.
- The interior temperature stays between 20 and 23 degrees regardless of the cold or external heat. Better than expected
- The performance of the Photovoltaic solar panels is very good. We are producing more photovoltaic energy than projected.
- The mechanical ventilation system has been a great discovery. Air quality and sleep improve significantly. Floating dust is drastically reduced.
- The passive solar design lets in the sun in the day in winter and not in summer. The solar angles on the terraces work as designed.
- We are happy to see that everything works as planned.
- We consider our civil and Christian duty to promote the use of renewable and sustainable energies and systems. If you need to take the house as an example with potential clients, testimonies, articles, etc., we will to support you.

Reasons for participating in the competition(s)
The house is located on an artificial terrace carved into the hill, joining it and facing north, taking advantage of exceptional sunlight conditions and privileged views of the valley.These conditions required to project a north facade with large windows to enjoy the view and solar gains in winter, protected by eaves which provide shade and prevent overheating in summer. Besides a large sun roof that covers 100% of the electricity demand and a surplus of electrical energy is injected into the public electricity network. 76% of the hot water demand it is projected.
The energy demand and consumption were determinedtrough PHPP software according to all Passivhaus requirements. Additionally tocalculate the Zero Energy balance a specific consumption profile was createdaccording to the expected Family activities and renewable energy systems wereintegrated in the design.
Thesolar thermal and photovoltaic systems contributions are 5.070 [kWh/y] and12.743 [kWh/y] correspondingly, based on calculations performed with Dr. Valentin Energie Software GmbH.
