Doors and windows repre-sent the worst points for thermal dispersion and cold bridge in buildings. The difficulties around using insulated and triple glazing windows is linked toto their costs and to their ability to guarantee the thermal envelope continu-ity. For one of these window suppliers the JPW company has provided a few examples of common UK wall structure in plan and section in order to allow this company to get the passivhaus certifica-tion. Most of the insulation retrofit projects are restricted by urban rules that most of the times avoid changing and incre-asing of external shape. Therefore we have managed an internal insu-lation that for several reasons has to be treated carefully to prevent moisture and damp into the wall and on the other hand an external insula-tion that can use the wall thermal capacity

This building, placed in Machynlleth in the middle of Wales, is a really old house showing several critical points for thermal insulation and prevention from moisture and damp duedue to an articulate shape and its orientation.The survey has reported few damages in particular on the wood structure of floor and ceiling and lots of wet patches on the slate walls. For this reason the study of archi-tecturaltectural details has been really interesting. The challenge was represen-ted in creating a thermal insulation, between jun-ctions with stone walls, that prevents all timber frames from water con-densation. The slate wall’s thermal inertia can create a huge temperature jump exactly in the padding joint. To avoid this is important to put a breathable insulation that can dry the damp created and a specific thickness of the

BIO FUEL PASSIVHAUS M+E SCHEMATIC

VENTILATION PIPES SCHEMATIC

As a representative agent of one automatic ventila-tion system supplier in the passivhaus field, we have received the task to design an aeration and heating system for two dif-ferent buildings typologies actually under construc-tion in UK. The first of these is a semidetached house having two separa-ted ventilation scheme: one needs 180 m³ air volume, the second one 120 m³. The different volu-metric contribution deter-minates the diameter of pipes and the powerful of the heat pump exchanger. Was interesting to solve some difficulties during the bigger apartment design due to the air machinery position far from the external wall. During Wales winter we have a really massive thermalthermal excursion between inside and outside, whereby avoiding very thick insulation around the pipes is used

to put a pre-heater just at the beginning of supply pipe making the air warmer. That prevents moisture and condensa-tion forming. The second project is made by three didifferent buildings which contain fifty-three apart-ments totally. First of all is necessary to calculate the entire air volume, after that we have to divide them between the right number of pumps. These last has to be put on the roof with heating system and the silencers. The system is centralized com-pletely. The ventilating distribution is through a main column that is l inked to a several V-Box which regulate the air supplying into the different ambient.

Within six months of my experience in this firm various experiences of interventions on existing buildings were discussed. With regard to the design from scratch I can give as anan example three different types of passive house concept in buildings: a social house, a barn and a factory. For each of these we tried to keep intact as much as possible the tra-ditional side in its form and in the choice of mate-rials. The break point for all three projects is a massive inclusion of glass and a roof garden. The first allows a break from the past with big walls of slate that were a charate-ristic of these buildings in favour of transparency, brightness and lightness. The second, as an addition on being an effective thermal insulation, blends the natural inclu-sion of modern architec-ture in both urban and rural environments.

The project area site is situated in Honduras at Copan Ruinas, not far from The Ancient Mayan City of Copan, one of the country’s most important archeological sites.AcknowledgedAcknowledged by Unesco as being under the protec-tion of the “World Heritage Foundation”, this site re-quires a particularly sensi-tive planning approach, dedicating full attention to its enviromental impact, from the morphological and material substances point of view.The plan is based on the Ecosites Model, scientifi-cally enviromental eco-parks, seen as instru-ments for the territorial management and for the promotion of learning activities, aimed at support-ing human development.

The museum is the only building which differs in shape and position.TheThe reason behind this is the desire to let art be per-ceived as a continuam in the passing of time and so a passage introducing itself into the present. Hence the tunnel form.

Museum

TheThe shape of the whole building is based on the study of the cross-section of the Mayan Piramids and on the role of the sun in the surrounding enviroment. The main building,building, although, very jagged and complex looking at first sight, actually turns out to be a simple tri l ite composition of wood. The height of the sections, the distance betweenbetween them and the thickness of the bamboo sails are directly connected with the study of the sun. With a maximum inclination of 87°, the sun never reachesreaches the glass surfaces that alternate between the sail sections. In this way the green house warming up effect is avoided. In addition, the large sails serve as heatheat removers for the electric conductors absorbing heat from the sun and releasing it immediately due to their small dimensions.The museum is positioned according to the direction of the winds, in such a

way as to prevent the damp air inside from stagnating. The wooden beams that make up the structure are divided up into primary and secondary supporting frames.frames. The former are double pillars anchored by a hinge on an upside-down T-shaped beam. These

are used both for the support of the beams in the ceiling and for those in the roof-covering. The beam in the ceiling is passed through two pillars and gets bolted to them. ViceVice versa the cross supporting beam in the roof covering, this is made up of two thin beams

The organization of the Firenze Castello area, near the airport, proposes the new placement of the Tuscany Region firms and its administrative offices.ItIt is an opportunity for a new approach to decon-gest the urban system and improve the quality of the suburbs. The project includes the inside history of the Florence evolution, but decoding the form in a modern thought. One building destined for offices and administration andand another that would represent the Town Hall.What better chance of studying the purpose of fifteenth century admini-strative building: “the Uffizi”. Instead for the represen-tative building I had been studying the ancient town hall: “Palazzo Vecchio”.Both of them are full of meaning and they are the symbol of Florentine society and culture

From the scanning of the prospectus with the Leica scanner laser 2500 and a following revision of the point clouds, it has been possible to complete an initial analysis of the degradeddegraded area of the building, also visible through the naked eye but more efficiently traced thanks to “false colour” obtained by the scanning of the scanner. The artificial stone, being the absolute predominant material in the building of the facade takes on shades of green in the less affected zones, and progressing through variousvarious shades of yellow, becoming orange in the areas heavily stained by dust and smog.It also possible to notice that the areas which are particularly blackened are predominantly in the pro-truding parts and in the indentations. The most striking feature is the stain

positioned on the left of the opening on the second floor.TheThe mapping of all these degraded areas have revealed the poor air flow exposure preventing the efficient removal of the deposited particles due to the presence of water.

STATIC DEGRADATION

TheThe second survey of the building deals with the building technology and the evaluation of the cracks identified on the outside of the building.AA research carried out on the Liberty techniques as made it possible to identify in the artificial

facade covering, the material the prospectus of the building is made up of. This was obtained by spraying a mixture of concrete onto an iron grids, purposely inserited into the supportingsupporting structure made up of bricks. Therefore, the nature liberty styles were obtained through modelling on site.The cracking that can be seen today is due to the partial coming away of this layer of concrete that is slipping down because of an underneath landslide caused by water infiltration.NeverthelessNevertheless these lesions have not affected the brick built supporting structure.
