Retrofit: energy improvement of existing buildings

Wednesday 30 September - 10.00 a.m.
Galleria dell'Architettura

The high standard of energy performance and environmental sustainability in new building is an increasingly common requirement in the national and local Italian standards and is increasingly being perceived by professionals, particularly as a result of the activity of certain qualified training and certification bodies.
These virtuous practices need to be extended to the entire existing building stock, particularly in Italy where obsolete buildings make up the vast majority and may present particular critical features (such as a high degree of obsolescence or artistic-architectural value). In these cases the challenge is even more critical and concerns both the building shell and the utilities.
Retrofit operations aim to improve the existing building stock by introducing performance characteristics that were not originally present. Retrofit does not fall within maintenance activities as it represents an update, an adaptation of the building in specific relation to energy efficiency but by extension also to other functions relating to the environment and sustainability. These operations may include integrated design solutions for the production of clean energy; the introduction of new technical elements in the building shell to control the sun factor; energy saving obtained by introducing new layers in the building shell and in the partitions. What role should building materials play, particularly ceramic tiles?

Redevelopment of the basic historic fabric: project for Brennone 21 in Reggio Emilia

Energy improvement of the basic building fabric of the Italian historic city centres is unavoidable. Maintaining it as it is would be the fastest route to rapid destruction.
The objective of the project Brennone21 is experimentation into planning methods and techniques for defining typological and energy remediation of the basic historic building heritage and for creating zero-emissions architecture in the historic centres of cities.

Biographical notes
Born in 1964, aggregate professor in Architectural Composition at the Faculty of Architecture of Ferrara, he carries out research and experimentation in the field of architectural design as well as studies into the relationship between project and construction and the relationship between architectural planning, sustainability and energy.

Technologies and components for energy improvement: the contribution of ceramic


Ceramic has always been an important building material and over time has maintained and even improved on its traditional functions. Now however it has become the focus of attention for study and R&D to develop new and previously unexplored functions for achieving energy saving and sustainability in building. The report discusses the main trends and their results and expected future consequences, as well as new product types.

Biographical notes
Degree in Industrial Chemistry from University of Bologna. Coordinator of Advanced Technical Ceramics Section of Centro Ceramico Bologna, Centre of Research and Experimentation for the Ceramic Industry – Laboratory of Emilia-Romagna Region High Technology Network – and director of the Centro Ceramico thermal analysis laboratory.
He works on national and international research projects with specific scientific management roles.
He carries out scientific and research activities in the following fields: preparation of colloidal suspensions of ceramic powders, technologies for forming advanced ceramic materials (slip casting, pressure slip casting and injection moulding), functionalisation of ceramic surfaces.
He has written more than 70 scientific and general publications on the above themes in various Italian and foreign trade magazines, monographs and books

Air conditioned zone concept

Stefan Hitthaler

Designer – Consultant for CasaClima
Air conditioned zone concept

New residential, commercial and traffic areas are continually being constructed, sacrificing land and energy.  This trend could be reduced by using areas that are already intensely constructed and by adopting structured corrections. The principle of compaction is based on improving the energy balance, density and quality of living. In order to expand, energy must be saved. The new settlement models will derive from interdisciplinary work, cooperation between urban planning, architecture, energy efficiency, sociology and economics.

Energy retrofit of historic buildings and integration between building shell and utilities

Giacomo Bizzarri

Lecturer and Lead Researcher at E-FAF – energy laboratory at Ferrara Architecture Faculty
The article presents a summary of the Energy Plan of the Municipality of Reggio Emilia and the subsequent research activities within the context of the European project LIFE-LAKS and ECO2Regio, for computation of the benefits deriving from the various energy policy actions promoted by the City Plan.
The adoption of a rigorous methodology overseen by a well-known international body by way of arbitrators has led to the conformity of the procedures followed being certified to the requirements of standard UNI ISO 14064-2, thereby making them suitable for obtaining energy efficiency certificates in the future.

Lecturer and Researcher at Ferrara Architecture Faculty

Energy improvement and housing programme

Ottagono, together with the Faculty of Engineering of Bologna, the Faculty of Architecture of Ferrara and the Faculty of Architecture of the University of Bologna in Cesena and the city’s leading building firms, addresses the them of energy improvement of the building stock in Bologna constructed from the end of the second world war to the early 1990s, particularly in connection with the regional law for implementation of the government’s Housing Programme. Three cases will be discussed: IAN CASA, PEEP and terraced housing development in the 1980s
