Lizza Dileyni Díaz de Oleo has made her final work of the Master's Degree in design and management Environmental of Buildings (MDGAE) of the University of Navarra in the study MADC & Partners, in Madrid, where she has collaborated in the energy optimization of a project for an office building in Castellana Street -former headquarters of the CNMV-, which finally has result winner in the competition.

The work of the recent graduate has consisted in bringing the project up to nZEB (nearly zero-energy buildings) standards: "Part of my work in nZEB standards was the study of climatic conditions, such as temperature, rainfall, humidity, winds and solar radiation, important aspects for designing measures to ensure the building's energy self-sufficiency, which were then included in the project", she explains.

The building at Paseo de la Castellana 19 is a century-old mansion that will be rehabilitated while maintaining the protected elements and at the same time transforming it into a first class building, "with a modern image and design and with optimal indoor air quality and comfort," adds the specialist in design and management Environmental Building.

In addition to the MADC & Partners studio, of architect Miguel Ángel Díaz Camacho, the project was carried out jointly with the RLA & Asociados studio, of architect César Ruiz Larrea; both new members of the academic staff of the Master's Degree MDGAE of the University of Navarra.

Reduce primary energy consumption by 59.63%.

Lizza Dileyni Díaz De Oleo - a native of Santo Domingo, Dominican Republic - explains that once the variables of design were studied, "the most favorable ones were chosen, which will reduce consumption to 45.41 kWh/m2 and reduce the primary energy expense by 59.63%". "In the proposal the energy simulation was contemplated with active systems that include renewable energies through photovoltaic solar energy and geothermal energy. The energy simulation to obtain the building's nZEB standard was carried out in the Design Builder program, and the calculation engine used for the results was EnergyPlus+," the postgraduate explained.

It was precisely in the course of the Master's Degree MDGAE at the University of Navarra when Lizza entered contact with concepts such as the PassivHaus standard, LEED and WELL certifications and other principles related to the nZEB standard, "necessary to achieve spaces that combine low energy consumption, low CO2 emissions and healthy and comfortable interior spaces". "During the development of the Master's Degree", he adds, "I had the opportunity to conduct workshops in different programs, such as CE3X and Design Builder, with which we perform energy simulations of buildings in their current status to compare them with the final status of the building after applying passive and active measures, and depending on the climatic conditions of different locations.

"There are other concepts that I learned at Master's Degree that do not apply at this stage of a project, but are necessary to ensure that the rehabilitation of the Building is nZEB, once the construction process is completed. These are the airtightness of the building - which is determined by Blowerdoor tests and also by thermographs to detect infiltrations/exfiltrations and thermal bridges - as well as the correct selection of materials and a design that allows for their proper disposal at the end of the useful life of the Building, so that it is governed by the principles of the circular Economics ", concludes the new expert.
