Owner approach of sustainability

In 2017, the City of Pesaro launched a pilot project with the aim of encouraging a holistic approach towards circular economy principles to ensure the building design responds to environmental protection, health and well-being and other social considerations.  The ambition of Pesaro City is to accelerate the transition towards a circular economy, enabling construction firms to use a new system beyond the current outdated ‘take-make-dispose’ model and contribute to mainstreaming the circular economy concept within and outside the city. Instead of taking a traditional approach to developing works procurement, the city decided to adopt a more circular approach which would be to build a sustainable new school using the current asset.

The ecological footprint of the building was at the centre of attention since the design phase and improved in the tender process to increase the building adaptability, durability, and resilience in accordance with the circular economy principles.

The intent was to optimise circularity and enhance the use of sustainable building materials and technologies, save raw materials, and minimise waste from the construction of the building. The analysis of not only educational needs but also citizens expectations for use was the central theme: to make the building more circular in terms of its functionality and make sure that it can be used by everyone all day, every day to become a wonderful community space for all the citizens.

The environmental impacts were improved by the tendering process to build a low energy concept school using good design to support not only passive heating and cooling technologies, but relevant active mechanisms as needed. Moreover, considering how green requirements will affect the procurement process for works and implementing them in line with the legal obligation, materials and methods of production and provision are considered when defining appropriate selection criteria. As a result, the tender includes technical specification on energy efficiency, product lifecycle, waste management, water efficiency with attention paid to internal comfort to create the best indoor environmental conditions for the students and teachers. These results are guaranteed by the environmental energy certification made mandatory in the tender notice and measured in accordance with the Minimum Environmental Criteria (MEC).

Architectural description

The project consists of replacing three old army barracks built in 1950 with the new middle-school located in a green abandoned area surrounded by a very densified neighbourhood of Pantano, near the city center of Pesaro. The decision of the municipality was made to reuse the site for a school with zero land consumption by redeveloping the abandoned urban area.

The program includes in addition to the construction of the school also the construction of a new gym at the service of the nearby elementary school. The plans of the school-gym are in progress. 

With a gross surface area of approximately 2430 m², the school will accommodate some 375 students in 15 classrooms and 6 classrooms for special activities and one for music, a teacher meeting room, a canteen, multipurpose spaces, and a library also open to the local residents.

Since not all the stundents of the school use the canteen, it is also at the service of the primary nearby school. The canteen is planned to suit the needs of the families.

Even though it is strictly speaking a school building, the municipality aims to reach further and optimise circularity, so it is designed to act as a catalyst for the whole neighbourhood and its residents.

The analysis of not only educational needs but also citizens expectations for use was the central theme: to make the building more circular in terms of its functionality and make sure that it can be used by everyone all day, every day. To respond to this need, the entrance is a big hall to encourage circulation and interaction with others, so people can, meet others and stay to chat. The big hall has been planned as a mixed-use space that can be used like a conference hall by teachers and citizens. The design of the circulation pattern itself encourages people to sit down and use the circulation space.

The structure of the building is composed with reinforced concrete supporting partitions needed for the development of the double height space entrance hall and with the timber structure for the roof to contribute at achieving low environmental impact.

The classrooms are all located on the ground floor and the first floor and are visually linked together thanks to the glass walls, and the broad and bright corridors are designed to trigger spontaneous encounters and joint teaching and learning moments throughout the day.

By opting for a compact volume, the design was managed to minimalize the footprint and avoided further densification of the neighbourhood by simultaneously providing more than ample outdoor playground for the children with sport facilities.

When planning the building, relevance is given to thermo-hygrometric comfort, acoustic comfort, correct use of natural and artificial light, optimisation of the building envelope to maximise free benefits of the sun, appropriate use of water, choice of materials, use of appropriate technologies to maximize the energy performance with adjustable solar shading and green roof designed not only to insulate but also to mitigate water use and the heat island effect. All these features were part of the requirements for tender, so the construction firms had to respond to these criteria as part of the bidding process.

The coloured façade of the building is composed of a modular system of porcelain stoneware and finished with earthy colours introduces a smoothly playful dash of colour in the streetscape. The characteristic colour provides a strong and recognizable identity and establishes the school as a playful, eye-catching beacon for this vibrant neighbourhood.

If you had to do it again?

I would study better the impacts of the materials to prove the circularity of the building, as if it was a bank of materials.
I would improve the eco-design and the use of bio-based materials to assure that the building would be dismantled as much as possible, to maximize the quantity of re-usable materials.
I would also improve the use of light structure assembly technology to have a clean and environmental friendly construction site.

Building users opinion

Users are generally very satisfied. Four categories are considered: the point of view of the teachers, the students, the school assistants, and the parents.
A campaign to collect data is already planned. It should consists of individual reports and interviews, but due to the present COVID-19 situation, it hasn't started yet.
All users appreciate the brightness of the natural and artificial light as desired, the acoustic comfort due to the absence of background noise in the classrooms or any noise disturbance from outdoor, the thermal comfort which is tailor-made in every classroom thanks to the sensors, and the view of the park surrounding the school.
The students appreciate very much the glass walls of the classes that allow them to see the other classes, thus generating a sense of community.
What users especially liked the most, particularly the parents, is the indoor air quality (especially considering the present COVID-19 situation) thanks to the mechanical filtered ventilation climate system, with a CO2 monitor, able to guarantee higher levels of indoor air quality, reducing the risk of contagion.
The general opinion is that this school creates an environment friendly spaces where students can be educated on sustainability, aware of being part of a community, and can understand how important the relationship between the human being and the environment is.

The air networks branch off to all the spaces with the presence of people (normal and special classrooms, library, teachers' room and presidency, canteen, etc.), so that students and staff always have constantly renewed air and high quality.

The only UTA (delivery and recovery: 15,000 m3/h) has EC plug fan fans (head: 300 Pa delivery; 200 Pa recovery), F8 filters (renewal air) and M5 (expulsion), plus a promiscuous battery for heating and cooling. The ridges run through the suspended ceilings of the corridors and branch off towards the individual rooms (maximum airspeed: 6,5 m/s for the main ducts; 4,5 m/s for the distributions). Instead of using galvanized sheet metal for the distribution channels, those installed are made with sandwich panels composed of :
- rigid foam of polyurethane foam as a structural element,
- coating on both sides with zeolite-treated aluminum foil to be antimicrobial.

The nanostructured coating returns a surface in contact with the extremely smooth air that, also thanks to the absence of sharp edges, giving the channels self-cleaning property, thus reducing the need for cleaning of the channels.

Also to the benefit of air quality, the surfaces of flexible ducts are treated with the technology effective against 600 strains of micro-organisms and certified for the reduction of the proliferation of pathogens. The plenums are equipped with linear vents (2 of discharge and 1 of recovery, for each classroom or large room, in order to contain noise emissions), installed on the wall or in special lowered ceilings inside some rooms.

The exhaust air extraction system from the toilets has also been extended to the service rooms (warehouses, cleaning).

The mechanical ventilation and heat recovery system optimize energy performance, with an improvement of 42% of the performance of the building compared to the reference project. The design of the ventilation system has been carried out with a BIM system, in order to solve in advance any interference.

A thermal generator with a backup function of the heat pump with a 150 kwt boiler (T sent 40°C) with modulating burner has been installed. It provides complete backup for the winter period, allowing not only to support the operation of the heat pump in periods of low outside temperatures, but also to face the entire thermal demand of the building.

The increase in power is also accompanied by an increase in efficiency, from 104.6 (50 to 30 °C) to 109.4 (40 to 30°C) and numerous other advantages, including:
- low start-up emissions due to modulating burner and high-water content of circuits,
- minimum climate-altering and polluting emissions from the surface burner;
- increase in thermal recovery from condensation (up to 6%);
- rapid adjustment of operating times;
- simplification of the methane distribution system, with a consequent reduction in safety risks;
- high thermal comfort thanks to the detection of external temperature and solar radiation (by weather forecast);
- control of management costs;
- low maintenance costs due to low emission combustion and self-cleaning Al/Fe heat exchanger.

The installation of the most powerful boiler did not involve changes to the layout of the technology plant, nor to the layout of the fluid distribution networks that, before reaching the terminals in the environment, are stored in an inertial accumulation (1,000 l). This has also reduced the consumption of electricity by the circulation groups, due to the high-water content of the circuits. The production of the ACS is entrusted to a boiler-type heat pump with double coil, integrated in its storage tank (295 l). There are also devices for water softening and dosage of polyphosphate salts and legionella disinfectants.

The air conditioning system consists of:
- heat-cooled main heat pump generator, installed on the roof, with an additional methane boiler located in the technology plant;
- thermostatic storage upstream of the fluid distribution networks, which supply the radiant floors and the primary air plant with heat recovery.

The renewable energy system installed has a decisive impact on the performance and overall quality of the services provided. It is installed an air/water high-efficiency reversible heat pump, with powers equal to 135 kwt (water to the condenser at 30 to 35°C and external air at 7°C b.s., that is 6°C b.u.) and 113.5 kWf (with water to the evaporator at 12 to 7°C and external air at 35°C), of the silenced type.

The heat pump can produce water up to 55°C with outdoor air temperatures even of -6°C, and up to 40°C with an outdoor temperature of -15°C (the winter design temperature for Pesaro is -2°C), so it can also work for pre-heating of the ACS upstream of the relevant kettle. In summer, the water can be produced at 7°C with outside temperature up to 46°C.

This system leads to a significant increase in the energy efficiency of the generator (COP 4.15; ESEER 4.03), even when operating at partial loads. Despite the extension to the entire building of the mechanical ventilation system, the improvement also achieves a significant step forward on the front of primary energy.

In addition to the air used for heat exchange, the electrical absorption necessary for the operation of the generator refrigerator comes from energy "green", through self-consumption of the production of the photovoltaic field placed on the cover of the school and withdrawal from the grid of electricity from certified renewable sources.

From an environmental point of view, the main advantages of the improvement is the drastic reduction of the consumption of fossil energy sources and CO2 emissions into the atmosphere. You have in detail (compared to the requirements of the race):
- 0 p.p.m. Nox (-100%);
- 0 p.p.m. CO2 (-100%);
- expected annual emissions of 2,420 kgco2 (-86%);
- expected annual economic savings of EUR 1,052 (-84%).

From the economic point of view, it also records a significant reduction in operating costs, further increased by the installation of an additional heat pump, the same type and size of that proposed as an improvement, to ensure continuity of service and increase in the useful life of the generator. The building is equipped with a photovoltaic generation system located on the roof and with a specific power of 28.8 kwp thanks to the installation of 96 monocrystalline silicon panels with a power of 300 Wp each. The PV system is installed on the central part of the roof of the school building, with an inclination equal to 8, with anchorage to the structure according to the indications in the structural tables and with monocrystalline silicon panels 300wp.

Renewable energy: Optimal production of electric energy due to the PV panels
•Photovoltaic installation of 158,40 m2;
•n. 96 photovoltaic modules of 300Wph and 1,96 m2 each
•Photovoltaic power ratings 28,8 Kw continuous current
•Inverter Solaredge 27,6KW alternate current
•113,5 kW heat pump
•heating system: floor heating and VAV system (variable air volume)
•cooling system: floor cooling and VAV system (variable air volume).
The electricity produced by the PV panels also feeds the boiler for hot water production.

Solutions enhancing nature free gains :

The shape and position of the building was studied and orientated to best exploit solar radiation and optimize the free solar gains and natural lighting and shading: the main axle is oriented in the north-south direction.

Smart Building

BMS :

The building has been provided with the installation of BEMS system for the control of the operation and the regulation of thermomechanical systems according to needs, which includes:
- continuous monitoring of weather conditions;
- detection and regulation of thermo
-hygrometric comfort parameters;
- hygienic replacement of air according to indoor CO2 levels;
- operation of thermo-refrigerators, UTA, networks and terminals. In particular, the motorized actuators of the KNX type valves allow a finer regulation of the operation of the radiant floor circuits (0 to 100% in continuous), depending on the temperature of the individual room, with the possibility of minimum attenuation (2 to 3°C), in case of short periods of occupant absence, and "energy savings" (4 to 5°C), in case of closure of the building.

BEMS is an integral part of a wider building automation system, which also deals with:
- management and control of electrical and special installations (artificial lighting controlled by brightness and presence sensors, supervision of photovoltaic installations, etc.);
- solar radiation and the operation of obscuring systems;
- accounting for electricity consumption from the grid and energy production by the photovoltaic system;
- accounting for thermal and water consumption;
- maintenance of installations.

The system used an ethernet network with Bacnet over IP protocol. The implementation resulted in a class A system (according to EN 15232), aligned to the requirements of the CAM and functional also to the LEED certification of the building. Smart grids will be developed to join the plant system of the new school gym that is going to be built at the end of 2021 and the new primary school that is planned to be destroyed and reconstructed with also the reconstruction of the multi-purpose new buildings that are around the school. Thanks to the PV system of these 4 buildings, the municipality aims to develop a smart grid to provide renewable energy in the neighborhood with the intent to develop a smart green pilot district to scale up all over the whole city.

Smartgrid :

The monitoring of local energy production and consumption drop scenario is in progress and it has been developed by the Department of Industrial Engineering DIN (University of Bologna).

Users’ opinion on the Smart Building functions :

Students and teachers are very happy and enthusiast about the Smart Building functions: they realize how it is easy and friendly to obtain the best environment conditions in each classroom and lab.

Indoor Air quality

The school is equipped with a mechanical filtered ventilation climate system HVAC with a CO2 monitor able to guarantee higher levels of indoor air quality with the air exchange of 5 volumes per hour.

The air networks branch off to all the spaces with the presence of people (normal and special classrooms, library, teachers' room and presidency, canteen, etc.), so that students and staff always have constantly renewed air and high quality.

The only UTA (delivery and recovery: 15,000 m3/h) has EC plugfan fans (head: 300 Pa delivery; 200 Pa recovery), F8 filters (renewal air) and M5 (expulsion), plus promiscuous battery for heating and cooling.

The exhaust air extraction system from the toilets has also been extended to the service rooms (warehouses, cleaning).

The amount of volatile organic compounds (VOCs), such as formaldehyde, contained in construction materials are avoided by the requirements of the LEED certification and the Minimum Environmental Criteria mandatory in Italy. Most of the materials used are EPD certify.

Health & Comfort

Health & comfort :

As LEED project, this one had to comply with a ventilation standard used to achieve high indoor air quality.

The school is equipped with a mechanical filtered ventilation climate system, with a CO2 monitor able to guarantee higher levels of indoor air quality. Please note that in Italy natural ventilation system in buildings is sufficient by law. Natural ventilation significantly depends on the temperature difference between the indoor and the ambient air and the current wind situation. As a result, a sufficient natural ventilation cannot be guaranteed at all times. The ratio of the HAVC system installed is 5 volumes per hour of air exchange to guarantee a high indoor quality, since poor indoor air quality leads to, among others, headache, fatigue, and reduced learning performance. This mechanical ventilation system installed in the school ensure a continuous air exchange throughout the year creating the best health conditions within the school to also reduce the risk of contagion.

Comfort for all is guaranteed by a remote and customized temperature in all classrooms thanks to the sensors for thermal comfort and indoor air quality ensured by mechanical filtered ventilation climate system with a CO2 monitoring, able to guarantee higher levels of indoor air quality with the air exchange of 5 volumes per hour. In every classroom, a both natural and artificial light control system has been installed, and a high acoustic performance is obtained to create the best environment for learning and teaching.

Natural ventilation is also ensured thanks to opening in the upper window sections. If the climate is appropriate, natural ventilation can be established by the opening of windows, which would also reduce the building operating costs.

The amount of volatile organic compounds (VOCs), such as formaldehyde, contained in construction materials are avoided by the requirements of the LEED certification and the Minimum Environmental Criteria mandatory in Italy. Most of the materials used are EPD certify.

Last but not least the shape of the building and the connection with the garden through the numerous windows, the colour used for the door and ceiling, the functionality of the classrooms and the labs, and the wide halls where students and teachers can meet and have a chat, make this school also friendly and smart.
