PERSONAL PROFILE

I am an Italian native speaker. During my studies, I had the occasion to travel and to partecipate to the Erasmus program in Glasgow and I believe that this allowed me to see new things and cultures giving me the chance to open my horizons toward the world. My desire is to continue working and living in a diverse, multicultural and international context. During a full academic year in an English-speaking country (Scotland), I acquired good fluency in everyday speech as well as in the technical terminology of architecture and engineering. Furthermore, I have a basic knowledge of French and I am willing to improve my proficiency. I enjoy team work and organise the work between team mates and I feel determined to take up various challenges and to learn new working approaches. During the last years, I've approached the theme of buildings sustainability, in terms of energy consumption, enviromental impact and renewal energies, that I am willing to develop and to improve in the following years.

The context: The university objective is to invest in education, forming professional figures with a deep knowledge in agriculture, farming and forestry who are able to exploit local resources and to promote a sustainable development of the mountain envi-ronment. Nowadays, the exhisting structures are not sufficient anymore to carry out all the accademic activities; furthermore, there is a lack of facilities to support and host students coming from far away. The project is an attempt to solve these issues, imple-menting new functions for accademic activities and creating a small campus for student accomodations.

The project: The challenge was to interpret the new functional needs of the university, the spirit and the ambitions of the programme of studies, the context of the Alps in a project characterized by a low environ-mental impact which integrates with armo- ny in its natural surrounding. As part of the olistic approach

adopted and to implement sustainable choices in the project, the LEED (Leadership in Energy and Environ-mental Design) protocol has been used as a guideli-ne: the selection of the site, management of external areas and rainwater runoff, water consumption as well as selection of materials. A second objective of the project was to provide low energy student accomodations in line with the Near-ly Zero Energy ’s definition laid out by the European Directive 2010. Therefore, the Passivhaus phylosophy has been chosen as a model for the residences. A residential unit has been deeply analysed in order to evaluate its energetic performance. The softwa-re PHPP (Passive House Planning Package) has been used as a design tool, assessing all the time the implication of the design process on the energy performance. Finally, the outcome is represented by a building that meets all the Passivhaus criteria and places itself very close to the definition of NZE.

In the concept of the expansion, the accade-mic functions have been split from the resi-dential once and kept closer to the exhisting once. The layout of the site favours the inte-gration of the new project with the exhisting urban tissue. New functions for both, social and accademic purposes have been imple-mented, including a green house and gardens in order support education and the develop-ment of sperimental farming.

LANDSCAPE SECTION - Rainwater harvesting

The sustainability in terms of environmental impact of the new project was an objective of the planning phase as part of the olistic approach adopted. LEED was used as a guideline during the planning stage in order to evaluate the best choices to guarantee a high level of environmental performace. The distance between the site and the city centre, has been eva-luated in the selection of the area: The proximity to such ser-vices contributes at reducing the use of personal cars, fosters the use of public transport and the mobility by bicycle and by foot. In order to support alternative transportation, new imper-meable surfaces for car parks haven’t been created; To limit disruption of natural hydrology, the external permeable are-as have been maximised to reduce rainwater runoff, but also for social and accademic purposes. Part of the green surface has been restored through a green roof with sedum, which requires a low manteinance level. The rest of the green areas have been planted with local vegetation to reduce the need of potable water for irrigation and to favour on site infiltration of rainwater. Another strategy to reduce potable water con sumption and rainwater runoff is the system of cisterns that stores rainwater for reuse in toilet flushing, washing machines and the irrigation of the greenhouse.

ACCADEMIC BUILDING

GROUND FLOOR

FIRST FLOOR

BASEMENT

The Accademic building has been designed as a multi-purpose structure able to meet the needs of the “Università della Montagna”. Its look is characterized by a compact volume dis- tributed on three levels. The functions implemented inside are a new library and study rooms, an auditorium able to host events up to about 180 people, a cafetteria and a greenhouse. The latest takes place on the south elevation of the building and constitutes its main feature: it is conceived as part of the social, architectonic, energetic and educational concept of the project. It forms a space where free time can be spent during all seasons and where students can carry out tutorials and experiments for accade-mic purposes. Furthermore it acts as a buffer zone, reducing the heat loss through the envelope and contributes to regulate the internal climate of the building. A very important aspect was to guarantee shading and ventilation during the summer: sha-ding devices and apertures able to induce pressure gradients have been included in the design.

TYPOLOGIES OF SPACES

STUDENT ACCOMODATIONS

The student accomodations take place in the southern part of the site, where six different residential units form a sort of “alpine village”. The new volumes adapt to the site morphology varying the height of the units from three to two storeyes. The campus can host about 70 people. In the three storey units some services for residents are provided, such as laundry, study room and a common lounge. Other spaces ex- posed to north provide room for plants and machineries, for recycling and bike parking.Two typology of accomodations have been implemented in the resi-dential units: the first one is an autonomus one, with private bathroom and kitchen; the second one is a shared flat, with five single rooms and common living areas, kitchen and toilettes.The internal layout is carefully balanced to guarantee a right amount of sociality and privacy. Furthermore, the final design is based on bioclimatic priciples which allow the building to make the most of the natural resources of the site. Some of these priciples include internal distribution, orientation, natural ventilation, compactness of the buil-ding.Finally, with the help of the software PHPP, the characteristics of the internal layout and the envelope have been varied in order to optimi-se the balance between energy losses and gains.

In passive buildings, the resolution of thermal brid-ges is a paramount step to ensure a high perfor-mance of the envelope. Indeed, thermal bridges could cause a local drop in superficial temperatu-res, leading to condensation and mould formation and a consequent decay of the building material’s thermal properties. In order to calculate the ther-mal bridges and to evaluate the superficial tem-peratures in these points, the various nodes of the building have been analysed with the finite ele-ment software THERM. Superficial temperatures re-sult higher than 17°C on the walls and higher than 18,5°C on the floors.

OVERHANGS STUDIESThe materials selected are mainly natural, recyclable and not harmful to humans. The structural material is constituted by XLAM panels made of spruce fir timber. Timber is a renewable and eco-friendly resource: its light-ness allows also a good seismic behaviour of the structure. Since buildings made of timber are considered “light”, the interior wall finishin-gs have been realized with clay panels, which ensure a better heat storing capacity of the building in order to passively exploit free heat loads and improving its winter and summer performace. For this reason also the founda-tion slab has been kept within the insulated en-velope.

The space heat demand descibes how much heat has to be supplied to the interior space during heating period in order to mantein what is considered a comfortable indoor climate with a standard temperature of 20°C.Once all the characteristics of the envelope, the ventilation system and the shading coefficients have been entered in the PHPP, these had been varied till the heating criteria were met.The final specific heat demand of the residen-tial unit is very low, about 8 kWh/m2y which is lower than the Passivhaus standard of 15 kwh/m2y. The performance of the building envelope can be classified as A+ according to italian re-gulations.The heat load has also been calculated resul-ting of about 9 W/m2 and it occurs during the sunniest but coldest day. This value is below the Passivhaus standard of 10 W/m2. Theoret-ically, it would also be possible to heat the building by supply air only, since sufficient energy can be delivered to the air treated by the ventilation system.

INDOOR COMFORT

Sustainability does not affect only environmental or energetic issues, but it transaltes also in the comfort for the inhabitants. A good indoor envi- ronment allows to improve the health and the productivity of the users.For these reasons, materials have been carefully selected, resulting mainly natural, recyclable and not harmful. Furthermore the mechanical venti-lation provides fresh air to the rooms and living room, removing indoor pollutants and exhausted air from the bathrooms and kitchens with an exchange rate of about 0,3 h-1.Another fundamental aspect which affects indo-or quality is natural illumination. The big apertures that allow solar radiation in also provide a good amount of natural light and a constant vi-sual contact with the exterior making the alpine context also part of the architectonic concept. To verify the amount of natual lighting, the softwa-re Velux Daylight Visualizer has been used to analyse the daylight factor, which results higher than 2% in residential spaces and higher than 3% in the study room at the ground floor.

Natural Daylight

The building services needed to cover the various energy demands of the building are mainly based on renewable energy resources. Since the project is located in an alpine climate, passive strategies were sufficient to provide sum-mer cooling, such as shading devices, natural ventilation and massive finishes in the interior walls. Therefore, the bu-ilding services are considered to cover only the heating demand and the domestic hot water demand.The system is composed by the following elements:
