With an investment of US$7.5 million, the project developed 22 “passive houses” that save up to 80% of energy
The project that brings together 22 houses was built in the same place where an old abandoned factory was located.
In the place where a factory operated a few years ago, real estate developer Pablo Delfino carried out an exclusive residential project. With an investment of around US$7.5 million, Organa, the name given to the gated community of houses designed under the Passivhaus construction philosophy, covers 70% of a block in the Martínez area, province of Buenos Aires.
The story behind this ambitious project reveals an innovative approach to urban planning, since the only way to build in this area was through the reconversion of an old industry.
“San Isidro rewards the eradication of industries.” What we did was reuse an area within the urban fabric that was occupied by an abandoned factory, and thus give new life to a part of the neighborhood,” explains Gonzalo Arana, architect of Estudio Arana. And he adds: “We got the land from touring the area, we liked the location, the dimensions and we saw potential in it.”
The result is a set of 22 houses that extends to a target audience: “From young families looking for a green environment, as well as those from other complexes in the area,” says Alan Flexer, Entrepreneurship Manager at Inmobiliaria Narvaez , to Responsible for the marketing of Organa.
The former abandoned factory where the new gated community is now located.
The complex is located at Gral. Pirán 1298, in Martínez, close to the San Isidro Hippodrome, the Unicenter Shoping, the Plaza de Martínez and the San Isidro Golf Club. And, due to rapid market acceptance and demand, according to Flexer, 50% of the properties have already found an owner.
The construction has units of three and up to four floors.
As for their values, they are around US$350,000 for the smallest units, which face Cuyo Street, with 232 m², three bedrooms and three floors (which include underground parking with exclusive entrance). The units on General Pirán stand out for their four-level design, with access also from the basement, and prices range from US$385,000 to US$400,000 with almost 296 total square meters.
There are 22 houses that have a single common entrance with private security.
What is the passive house philosophy like?
“The Passivhaus philosophy has two important issues: energy savings and air quality. It is the second construction that meets these conditions in Argentina (the first is an entrepreneur from Mar del Plata),” explains the Entrepreneurship Manager at Inmobiliaria Narvaez.This type of construction deserves its name because it consumes practically no additional energy. For example, instead of relying on expensive heating appliances, these homes achieve optimal comfort through intelligent passivity.
The dining room is located on the ground floor of the units.
For Flexer, these constructions are also ideal for health, since they ensure continuous air renewal, in addition to being friendly to the environment.
Paolo Massacesi, the director of the Latin American Passivhaus Institute (ILAPH), explains that passive houses are built on a set of fundamental principles: high thermal insulation, absence of thermal bridges, high-efficiency carpentry, controlled mechanical ventilation, and high level of airtightness. At the same time, in Latin America it is added: solar protection and design in relation to the bioclimatic position with respect to how you want the home to be oriented so that it has the best possible thermal conditions. “This construction will reduce energy consumption in the area by at least 60% to 70%,” he states.
Regarding the costs generated, the director of ILAPH says that there are two key points: the initial investment and the energy consumption of the home. “In countries where mortgage loans exist and where energy is very expensive, transforming a traditional home into a passivhaus is profitable. On the other hand, in Argentina today it is very difficult to say because we are going through a stage of readjustment of our reality, but I believe that, those of us who have the economic capacity to be able to do so, must assume the environmental commitment”, he declares.
The bases of this construction are isolated from the earth.
According to the architect, the construction of passive houses was a great merit for leaving the comfort zone "investigating some new techniques regarding the rational use and conservation of energy."
In this sense, each unit in the project has a ventilation system that continuously renews the air, providing low energy consumption that can represent up to 80% savings on the monthly utility bill.
Additionally, the HVAC system incorporates heat pumps, which are significantly more energy efficient than traditional heating and cooling systems by moving heat rather than generating it.
The houses have a double ramp to access the underground garages.
The kitchens are equipped with furniture
Design and energy efficiency details include PVC carpentry with DVH, underfloor hot water heating, air conditioning in each room, exterior air exchanger/filter, motorized curtains, solar or wind energy on the roofs and pre-installation for chargers. electric cars.
The four-story units have a double-height desk on the second floor.
