We were asked to retrain the Primary School “Carducci” building envelope through the use of energy efficient technologies characterized by high architectural quality, proposing creative and innovative design solutions to give new image to the school. The building is in prefabricated reinforced concrete with space frames, built between 1954 and 1988, designed to accommodate an elementary school and a nursery school. The costruction is on two floors above ground: the vertical structural elements consist of 32 pillars 36x36cm (net of finishes) on the ground floor and 20 pillars 36x36cm on the first floor. The school is located within the urban network of Empoli, in Tuscany, corresponding to the Climatic Zone “D”. Here we have 1658 GG (Degree-Day), temperatures ranging from 0 °C to 31.5 °C and External Relative Humidity from 28.3 to 50.0% throughout the year. The daily temperature range in the summer months is 12 °C. After collecting the data from the climatic zone, we carried out a more detailed bioclimatic analysis on the building. The most disadvantageous situation is created in the winter, with strong winds of coming from north/north-east. As for rainfall, the most critical period is always the winter one with a maximum peak in November (100 mm). Using the online Sun Earth Tool program, we took the sun diagram for the maximum and minimum solar irradiation period, respectively on June 21st and December 21st. For each of the days indicated above, we studied the incidence of the sun’s rays and the relative shading in three different time slots: 9:00am, 12:00pm and 3:00pm. It is clear that the maximum incidence is reached on June 21st at noon with a tilt of 70°, while the minimum on December 21st at 9:00am with an inclination of 9°. In the analysis of the shadows we considered the surrounding buildings but we found that none of these significantly obscures the school complex. From the architectural point of view, we found several critical points. The building shows up a state of evident degradation, with different portions of the façade quite damaged, to be maintained or even to be replaced. The chromatic inhomogeneity of the building is very evi-

dent, probably caused by a limited freedom in the architectural composition deriving from the construction technology used, which shows the lack of unity between the architectural elements in the design. This compositional disorder leads to the total lack of visual references, which do not help the user experience within the complex. After a careful analysis of the current situation, we did a research on the most suitable technologies to be used for the energy improvement of the building. For the opaque vertical infills we decided to adopt the wall proposed by Knauf. The chosen coating, Aquapanel Outdoor, provides a thermal insulation on the facade, with slabs in fiber-reinforced cement, with characteristics of durability, resistance to water and weathering, making the laying of the insulating materials very simple. We used a 50 mm thick Fibertherm wood fiber produced by BetonWood as insulating material. For the covering of the roof slab we decided to use a green roof of the DAKU company. We chose a standard type of Extensive Roof, which guarantees the best compromise between weight, thickness and water self-sufficiency among the extensive green roof systems taken into account. We proposed it without the irrigation system: this condition helps to minimize the growth of weeds and allows to reduce maintenance costs. A layer of insulation has been added to the standard green roof package made of extruded polystyrene (XPS) to comply with regulatory limitations. The main purpose of this intervention was to give back some color unit to the building, going to cover it with a “second skin” that made it visually compact and uniform. The elements of major disturbance, such as entrance sheds and fire escape ladder, have been treated with colors lit and strong shapes, turning them from critical points into strengths in the composition of the building. Despite the choices of coating have been diversified for the transparent and opaque walls (wall “A” and wall “B”), we focused on the continuity of the façades as the main objective in order to obtain a result aesthetically pleasing with a minimally invasive intervention.

Library BIM modeling and Design Builder dynamic simulation Made in collaboration with Arch. Daniele Galuppi, Eng. Alessio Schiano and Arch. Matteo Pagliuca

For this work we were asked to model a library and to use a dynamic simulation tool to energy retain the building. As a start we shaped the library using Revit Software, which allowed us to design the digital representation of physical and functional characteristics of the library. Hereafter we have taken part to an energy competition. The task consists in the preparation of a “professional” report that describes and illustrates the benefits in terms of energy savings and efficiency solutions applied to economic model of building-plant for library use. The choices made were measured through dynamic simulations that have demonstrated their effectiveness in terms of energy, allowing us to calculate the time of simple economic return of the investment. All the simulation were made using Desing Builder software. The efficiency strategies that was adopted was chosen by assessing cost benefits which takes into consideration the energy performance, the savings achieved and the cost of the intervention through the financial analysis of the turn-around simple time. The aims were: • Minimize energy consumption per year (amount of gas and electricity) for heating, cooling and lighting • Minimize the intervention’s economic return (simple payback = work cost/fuel cost saved in one year compared to the base case)

With a limited intervention range: • Thermal insulation of the building envelope opaque • Replacing existing transparent surfaces with new high energy efficiency transparent surfaces, with solar control characteristics and optimum light transmission • Solar shading • Integrate control systems for natural ventilation • Integration of green roofs • PCM integration (optional) • Replace the boiler with a more efficient one or with a heat pump • Replace the cooling system with a more efficient • Insert heat recovery devices on controlled mechanical ventilation system The building of departure was not retrained and represents a possible technological configuration typical of centuries of construction prior to the introduction of the first legislation on reducing energy consumption in buildings. It has a great open volume in the ground floor, corrisponding to reading room, that has a large glass wall that cover the whole south surface. The interventions proposed can be classified into the categories used in Italian APE. It was mandatory to adopt strategies that are equally distributed among the categories in table 1.0: at least one intervention by category, unless the results demonstrate that, in a particular category, no intervention has convenience economical. There are no affordable efficiency strategies that have excessively long turnaround times — over the useful life of the component (30 years for building components and 15 year parts plant components). We have been create a remuse box of each of the upper sections, underlining the power saving of the solution and the corresponding economical investment. The bottom red number represent the simple return time of the investment. At the bottom side of the previouse page is possible to see the table representing the final solutions we have proposed for the Library. The first solution (the left table) involves vertical walls and flat roof insulation, windows replacements, inserting shielding sunblinds with fixed blades, air conditioning summer/winter plant with MVS and heating pump, MVS with heating recovery system, LED lighting system; with a simple payback of the investment of 18 years.

Asilo Nido Baloo/Bagheera Firenze,IT Energy AUDIT Made in collaboration with Arch. Daniele Galuppi and Eng. Alessio Schiano

Asilo Nido Baloo/Bagheera via dell’Agnolo 74 Florence (FI) Italy

Purpose of this work was to evaluate the energy consumption of the nursery Baloo/Bagheera. The nursery, which was originally called “Central Ward”, was built in 1952/1955 and was therefore one of the first kindergartens fiorentini; was renovated and expanded between 2006 and 2007 and further changes were done in 2012. The entrance of the nursery Baloo/Bagheera is in Via dell’agnolo 74, corner with Via Michelangelo Buonarroti. Looks like a “E”: the main body is facing South and is located on the main street, the three arms face the inner courtyard with a Northern exposure, two of which are adjacent to another building. The building is spread in elevation on two levels above ground (ground floor and first floor) and a third basement for technical rooms and the garage which is accessible via a ramp in the backyard. The main façade of 26.50 m is in white plaster and has a basement of blocks of stone Bush hammered by 1.50 m in height which reaches the string courses of the first level in the corner to the East and the prospect of Via Michelangelo Buonarroti. The building has a horizontal division is determined by the setting of the first stone stringcourse and reentrant metal railing from the balcony level. The entrance at street level consists of a large window with full height and iron shutters on all three floors there are openings in axis with a pitch of 2 m between them that they become doors for access to the loggia on the top floor. Part of the frames of the South elevation and towards the inner courtyard were replaced in the last renovations of the 2012 two-Chamber glass. The sloping roof recently renovated (2008) was made of tiles. The corners of the structure at the main facade to the South there are stairwells between the three levels of the building. The internal distribution provides a lift in the lobby listed in the operations of the 2006-2007 and a small staircase that leads to the mezzanine. This level is the main concourse dividing the rooms allocated to the Secretariat and the staff changing rooms to the East, and the classrooms of children on the West side of the school. The entire first floor accommodates classrooms, rooms for children’s meals and toilets. While in the

basement are intended for all service areas, such as locker rooms, industrial kitchen and pantry, deposits, boiler room, and the unloading area and garage. The thermal power station is accessible from the outside and overlooking the courtyard of the school. The basement and ground floor heating is provided through radiators, unlike the first floor where the heating and cooling system is provided by fan coil. The methodology used included a first phase of preliminary data collection relating to the site. After a diagnosis limits and framing of those involved went to analyze the Thermo-physical characteristics of the building envelope and the plants present. For each of the energy flows involved were then collected consumer data from invoices and/ or dedicated counters. The analysis of energy bills has helped define the building-system. Correction parameters, adjustment factors are the physical parameters of the building: square meters, cubic meters and degree day. Proposals for action to improve building energy management and get more or less significant savings on electricity bills. The proposals were divided into three levels, depending on their level of intervention costs. • Staff training the correct management of the building. • Replacement of existing lighting with LED lamps. • Install heat reflective insulating mats (in the cavity between the radiator and the wall). • Analysis of the behaviour of the building envelope and the possible intervention of improvement. • Installation VMC in decentralized system with heat exchanger. Please note that assessments made about the energy savings achievable and cost-related economic benefits the implementation of interventions are based on information available

to us, current consumption on some information techniques found in the field.
