Introduction
I work on the hybrid border between scientific research and design, to create a domain of common understanding and possibilities for experimentations. My main topics are: the use of photovoltaics in buildings (BIPV), and landscapes, with focus on trans-disciplinary perspectives and innovative cognitive frameworks for new design visions.

As an answer to the increasing demand for photovoltaics as a key element in the energy transition strategy of many countries—which entails land use issues, as well as concerns regarding landscape transformation, biodiversity, ecosystems and human well-being—new approaches and market segments have emerged that consider integrated perspectives. Among...
Article
Full-text available
It is widely acknowledged that the visual dimension of photovoltaics (PV) is fundamental for social acceptance. In this sense, the so-called Building Integrated Photovoltaics (BIPV) is a possible catalyzer, as PV is hidden (integrated) into building envelope morphologies that are familiar to the public. It is crucial to be able to design and assess...

The need for shifting to urban renewable energy integration and use is critical when the goal is decarbonizing the global energy system. Due to cities’ integrating framework, the energy transition in urban environment towards renewable energy can be achieved in all end-use sectors, not only in power but also in heating, cooling and transport. Solar...

From 2012 to comply with the ED 2010/31/EU and its recasts, all new buildings will perform as Nearly Zero Energy Buildings (NearlyZEBs). Buildings are going to be transformed through a careful design into energy generation systems, and the conventional, centralized system of energy generation is going to be replaced by a "web" of energy generation...
Conference Paper
Full-text available
A photovoltaic (PV) greenhouse has a part of its transparent covering replaced by (opaque) PV components. This system allows for a " double use " of the resource land, because it generates energy in the form of biomass (crops, or flowers, or algae) and, also, electric energy. In islands, where land is limited, the energy demand is increasing; the u...
Article
Net Zero Energy Building (NetZEB) design has become a crucial topic of research in recent years. Because of its complexity, discussion has been carried out on methodological criteria useful to define and assess NetZEBs (building system boundary, conversion factors, energy balance, interaction with the grid, monitoring, etc.), mainly with the engine...

Façades are the central element in the design and architectural definition of contemporary buildings. Several solutions, with different aesthetical appeal, perform the finishing materials of existing building and new constructions. A sustainable design process today is intended to produce high-performance buildings that are energy-efficient, health...

Article
Starting from the end of 2020, all new buildings will have to be Nearly Zero Energy Buildings (Nearly ZEBs—ED 2010/31/EU recast). This new ‘energy paradigm’ might be a revolution for architecture and for Photovoltaics (PV) too, but there are both cultural and technical obstacles to overcome. There is a need to re‐think the way buildings are designe...
Conference Paper
Full-text available
The energy topic has become increasingly important in architecture: since buildings are big consumers of energy and architects and the public are interested in energy as never before. [Scognamiglio 2008] The Energy Performance of Building Directive (EPBD) [EU 2010] establishes that starting from 31 st December 2020 all new buildings have to be Near...

Promoting whole building strategies that employ passive measures together with energy e...
Article
Thanks to a new energy consciousness, driven also by European energy policies and national feed in tariffs, photovoltaic surfaces are becoming part of the image of our cities and landscapes. Unfortunately, despite the increasing in the use of Photovoltaics (PV) in the recent past, its architectural quality still seems not always satisfying. In a nu...

Article
The shift from traditional fossil fuels to renewables is implying a diffusion of “visible” PV modules in our buildings and landscapes. In contrast with traditional fossil fuels, which were hidden in the ground somewhere, far from the city life, renewable energy generation systems, and Photovoltaics (PV) in particular, are visible. This change is ge...
Conference Paper
Full-text available
The energy footprint of an inhabitant of today's cities in industrialized countries is larger than usually assumed if all forms of energy, including nutrition, are taken into account. In a post-fossil fuel and de-carbonised society, more land surface area will be required to fulfil human energy and nutrition needs. The paper outlines concepts for f...

Thin film photovoltaics is a particularly attractive technology for building integration. In this paper, we present our analysis on architectural issues and technological developments of thin film silicon photovoltaics. In particular, we focus on our activities related to transparent and conductive oxide (TCO) and thin film amorphous and microcryst...
Article
Full-text available
The attention of the public for energy conservation is influencing the field of Architecture, and implies a new regard to the energy consumption of existing buildings, too. As a consequence, in historical cities, architects are asked to re-design buildings in order to improve their performance. For this re-design, very often, new energy production...
Conference Paper
Building integrated photovoltaics (BIPV) are currently one of the more diffuse application of the photovoltaic technology; but another important field might be investigated in our country (Italy), that is the integration of PV systems in the landscape. It means the installation of PV systems in valuable sites, characterized by an high cultural valu...
Conference Paper
An important subject to investigate in the field of the diffusion of photovoltaic systems is the development of landscape integrated PV components fit to the installation in valuable sites, that are characterized by an high cultural value (such as archaeological areas, natural parks, small islands). The aesthetic value of the components is the most...
Conference Paper
Full-text available
The new regard of our contemporary culture for energy conservation is influencing the field of Architecture. Photovoltaics is now seen as a smart technology useful to transform buildings into " cool " contemporary energy generators. This new symbolic status of Photovoltaics is creating new architectural and market demands. This makes it more import...
Conference Paper
Full-text available
One of the key of success for the building integration of PV seems to lie on the aesthetical aspect of the PV modules. The quality image issue is not so trivial since they are just the end users that need to be convinced to accept the installation and in any case the modules have to be integrated into the overall concept within the building design....

Renovation of existing residential buildings is an important field in Italy, where the building maintenance market is estimated to be in the near future about the 70% of the total construction market. [I] More and more often building maintenance is aimed to improve the energetic behavior of the building envelopes, and, consequently, to reduce the o...
