The construction going on in the street Sant’Antonino 88 is a first in the city: the first will be ready soon and wood house eco-friendly straw. The commissioner simplification and innovation Filippo Zanetti, together with the architect Jimmi Pianezzola (designer and director of the opera) and the engineer Constant Bonacina Casalogica of the company, explained the positive aspects of the construction of buildings of this type in city. Also present was the city councilor Everardo Dal Maso. “A wooden house and straw, the first in Vicenza, is an interesting novelty and an example to be repeated for the characteristics of eco-sustainability in the environment – said the Councillor for simplification Filippo Zanetti and innovation -. When, in the private housing office, we noticed this innovative project that would be developed in the context of an ex Bid we decided it had to be made known. The goal of the Bid is to give the opportunity to approach the family of origin: within certain constraints give the opportunity to realize the small houses at variance with the Zoning. The story happiest part of the Bid is the one of this house, made entirely of wood and straw, with innovative technological features with obvious energy advantages and sealing. The administration would like to promote this type of construction so that the building code that we are implementing want to encourage and reward structures that favor energy efficiency. ” The single house is made of pressed straw bales that distinguishes it from the point of view of architectural and construction from the current building practices for the study of shapes, low environmental impact, research on building materials used. The project is part of the activities for the satisfaction of the family housing needs charitable (ex Bid – Announcement of common interest): a total of 1,525 applications were received and 626 were accepted; of these to date we have reached 29 actual questions, of which 18 were considered to have the requirements, then they have got permission to build and are under construction. The project – thus imitating an idea of architecture linked to the archetypes of the building where a fence and a superimposed roof make up the family home – provides an enclosure that protects from the road or nearby car park, it opens to the garden and private patio bordering the south. The extensive coverage, the same size of the fence but rotates 90 degrees, welcomes and protects the entrance, creating a porch for life outside, leaves the sky over the patio. The latter preserves the life inside and at the same time is a water reservoir in cobblestones, integrated by a hydraulic system of communicating vessels for rainwater disposal, the garden of the micro-air-conditioning, the use of water in for irrigation. The heating and cooling of the house are designed ad hoc as the ratio of the openings and of the jetties with sunlight. The air-conditioning as the production of hot water and electricity are entrusted to a system of photovoltaic panels and heat pump with accumulation of water. The house is not connected to users of natural gas. The technology adapted and made system from Casalogica firm Brescia (innovative start-up in the construction sector with assets of many accomplishments) provides that the straw bales are used as a major closing infill brick of the wooden structure. The design system refers to “Nebraska” method of construction in the US nineteenth straw and the European tradition that developed in the early twentieth century and then taken up with new life in the nineties of the last century. This technique is cheaper by about 20% compared to the use of brick and has a low energy consumption, also the production process and the life cycle of the article employing low levels of the so-called “gray energy.” In case of fire in the wall of straw bales plastered on both sides has the triple strength compared to concrete masonry and steel.
