Edificio ad alto consumo energetico
A Passivhaus construction in central Italy, a temperate zone categorized as having cold winters and hot summers, that provides energy savings and reduces environmental footprint in a region where the technological requirements are burdened by the obligation to mitigate risk from high seismic activity. The structure consists in a light and flexible steel and wood beam frame with reinforced concrete dividing walls arranged inside the thermally insulated core that provide additional mass contributing to the passive thermal accumulation. This complex structure guarantees the stability of the building and minimizes kinetic energy resulting from seismic activity and contemporary reduces the risk of damages to the airtight envelope. The project is based on the Passivhaus standard to optimize energy consumption, and relying on the Life Cycle Assessment (LCA) method to minimize the impact on the environment. The philosophy of the project. Conceptual: by reference to the use of the golden proportion or ratio as a base for the architectonic geometry of the building, and to the use of the principles of Feng Shui. Architectural: by reference to the use of contemporary and non-vernacular indoor and outdoor design and materials. Environmental: by reference to the use of natural (such as wood, wood wool, aluminum, steel and glass) and/or recycled/recyclable materials, water cycle management, preservation of the permeability of the external surroundings, relocation of centenarian olive trees, reuse of the digging material. Ecological: by reference to the use of a solo ventilation system with heat recovery and subsoil heat exchanger both for heating and cooling, with a small contribution of a heat pump, passive strategies such as winter solar gain, summer solar protection, thermal solar system for domestic hot water (more than 80%), and photovoltaic panels to achieve energy independence with the use of solely self-produced renewable energy sources and such a main contribution to a real “close to zero” building end life environmental impact.

Approccio del proprietario alla sostenibilità energetica

The choice to build this sustainable passive house depends about ethic reasons, connected to the wish of reducing the environmental impact and the energy consumption in a country like Italy that import the main part of the energy that consumes, from the wish to minimize the management costs and from the wish to reach a very high level of indoor quality living, level that it is impossible to reach with conventional construction methods and techniques.

Descrizione architettonica

The architectural design is based on an holistic and interdisciplinary process of
the place-architecture-envelope-mechanic system, implemented by passive energy gains
and passive protection against energy dispersion and indoor summer overheating.
The choice of a contemporary design, the use of low environmental impact and non-vernacular materials, such as natural wood and aluminium, and the design of a structurally anti-seismic and extremely high energy
efficiency building with reduced operating costs, are parts of the requisites of the project.
The architectural setting makes use of the golden proportion or ratio (the golden number - φ ≈
1,61803) as a base for the architectonic geometry of the building, and of the principles of Feng Shui.
A special attention paid to environment protection: relocation of dozens of centenarian olive trees; the choice of natural construction materials, mainly recyclable; the management of worksite waste; the reduction of drinking water consumption and rain water recycling; the preservation of the permeability of the external surroundings due to gravel or green surfaces, the reuse of digging materials; the minimization of the environmental impact.
