Master’s Degree Thesis Environmental Design, Building Design, Thermal Comfort, CFD Analysis of a ZEB

ABSTRACT: Zero Energy Buildings require airghtness and mechanical venlaon systems to provide air changes

and energy saving. These requirements contrast with the principles of natural venlaon. Through a case study

located in Modena, Italy, a design strategy is proposed as a soluon to integrate natural and mechanical venlaon

systems at dierent mes of the year to reduce the energy consumpon in a newly designed high-density ZEB.

The internal comfort evaluaon for the warm season is then veried with a mulzone dynamic simulaon and a

CFD analysis. The proposal consists of two dierent approaches, the cold season and the warm one. For the cold

season, a mechanical venlaon system with earth tubes and heat recovery has been designed, together with

airghtness, solar greenhouses and high thermal mass and insulaon. For the warm season the design allows afree-running use: open trickle venlators applied to windows which provide background venlaon, mass and

insulaon migate the heat loads, vercal venlaon shas support natural venlaon and free night cooling. The

venlaon shas have been designed with aerodynamic principles to provide each apartment with addional (and

maximised) dierences of pressure due to the stack eect. The indoor comfort condions in the warm season are

then evaluated according to the ASHRAE 55 adapve model for free-running buildings.

The results of the study conrm that in the warm season acceptable indoor comfort condions can be achieved

in a free running building. The venlaon sha has an important role for the free cooling of a ZEB and can also be

adopted in the renovaon of exisng buildings.

The Green Courtyard Architectural Design of Residenal and Commercial Housing

Located in western Bologna in the middle of a regenerated quarter, this residenal complex faces the main square

and is surrondend by pedestrian walkings leading to a park. The inner and the external fronts have been dieren-

ated creang an inmate courtyard for residents and a representave front to the square and the public walks

where shops are located. Apartments have dierent sizes. Duplexes are located in the two upper oors, each one

furnished with a terrace and protected with an overhanging cover. Sliding panels surround the whole building to

protect from sunshine, except to the north where facades are enclosed to reduce heat dispersion.



Wroclaw Gate & Media Wall Urban and Architectural Planning, Deepining Into Two Buildings

Wroclaw is an important, dynamic and modern city located in south-western Poland going through a great urban

regeneraon, especially in the closest suburbs to the city centre. The locaon of the project is a strategical point

where the highway from Warsaw comes directly into the town. It was demanded to create a “sign”, something

iconic and “green” that would have become a symbol of the town. A Media Wall has been designed as a protecon

from the trac noise, covered with solar panels and with a led-lighng-system just behind the panels. Surround-

ing areas are essenally residenal or managed by University, with classrooms and student housing. An exisng

Mall stands just 500 metres away. Wroclaw University owns this ground, so buildings have to be compable with

academic uses.

White Apartments Architectural Design of Residenal Housing

It has been the rst project ever developed in a team. It was an exercise where structure and ground modelling

were given as invariant. A housing building had to be designed in a neighbourhood street with other buildings on

both sides. The concept consisted of creang four blocks separated by cornices. Each one is composed of blocks

(apartments) sliding over one other and creang in this way terraces for upstairs ats. All facilies are located at

the ground and underground oors.

Acs in Historical Buildings of Bologna (will be published)Conservaon - Restoraon Study and Design of Wooden Acs

Bologna has the biggest medieval historical centre in Europe and despite an architectural masterpiece is missing in

town, there are lots of magnicent buildings spread all over the city. Bologna istuons want to emphasize the im-

portance of Bologna on the internaonal scene creang a “historical atlas of Bologna”. Students of the University

are challenged to a great task to put the bases for this vast collecon of studies on buildings. Divided into groups,

all students have to lead studies of the most important buildings in town and literally to discover new treasures

in private and hidden houses. Studies on the various subjects have to be done based on historical and technical

proles, consulng historical archives in all the country (Bologna, Florence, Rome).I worked on wooden acs and produced a 165 tables work that was menoned with honours by commiee.

Ecologically Equipped Producve Area Urban Planning and Architectural Design

In the Reno-Galliera municipality, located in the northern province of Bologna, a new producve area will be devel-

oped. Aer consulng and analisyng public data, the Funo area was choosen for the project. The task also included

choosing a compable industry to Bologna’s region economy. A center of fruit processing was chosen to be designed,

a sort of “green industry” that would have become a point of reference for the whole region. It wouldn’t have been

just a factory, but a complex that involves open-air exposion areas, gourmet shop/restaurant, agricultural lands and

industrial areas. Manufacturing itself becomes part of exposion, so visitors can get in and look at the producve

line. Many devices have been thought out to reduce environmental impact, for example producvity lines embody

low-impact, some processes can be done without energy (such as drying fruit) and some others recycling processingwaste. A detenon basin is located next to the built up area and becomes an integral part of the system. A composng

plant is also located in the area.



Structural Calculaons - FEM soware Samples of Drawings, FEM Modeling and Analisys

I worked on calculaons for a whole steel building as well as a concrete one, from roof to foundaons. Calculaons

were done according to Italian and European laws, using both allowable-stress method and limit state design, rst

done by hand and then veried with soware. Drawings were produced at each single step of the calculaons.
