Cristian Angeli is the author of the book:
“BUILDING SAFETY, EFFICIENCY AND COST SAVINGS”
The idea of this book directly followed the realization of how scarce the information is on the scientific research carried out all over the world on ICFs. These studies were conducted through testing and experimentation and offer scientific evidence on the economic safety and energetic benefits of the ICF construction system. Therefore the author of the present book collected analyzed and catalogued by typology fifty pieces of research that are now available for rapide use and easy consultation.
The collective reading of these works shows that ICFs make a construction system with a relevant and internationally consolidated scientific background concerning both the usual performativity and exceptional aspects like explosions and tornadoes. Each summary is followed by a few explicatory lines listing the topic and the references to the author.
The volume also presents an introductory part in which the main specifications of the ICF system are described and a section devoted to the pictures of buildings under construction to better illustrate this construction technology
Cristian Angeli is the author of the manual:
“SISTEMI COSTRUTTIVI A PARETI PORTANTI IN C.A. – INSULATING CONCRETE FORMS /CONSTRUCTIVE SYSTEMS OF LOADING BEARING CONCRETE WALLS – INSULATING CONCRETE FORMS”
Legislazione tecnica, Rome 2018
This publication describes load-bearing concrete wall constructive systems, made of polystyrene formworks (known as ICF, Insulating Concrete Forms).
It deals with the matter in a organic and multidisciplinary way, because it talks about the planning, executive, scientific and industrial aspects, highlighting the most important characteristics, from the structural and energetic point of view, to fire behaviour, costs, executive methodologies,regulatory and fiscal aspects, and possible critical issues.

The art of building has evolved over the centuries, based on the experimental (or rather occasional), detection of the good functioning of the works already created, or the inventiveness of few manufacturers who, guided by intuition, have conceived new geometries and new solutions.
The structural safety and environmental sustainability of the buildings, at this particularly challenging time for our country, because of the recent earthquakes that struck Central Italy in 2016, represent themes of fervid discussion in the world of professionals and businesses, involved in another complex cycle of reconstruction of thousands of buildings, which are damaged or destroyed by the earthquake.
The main and deepest need, without doubt, for people who have lost a lot or even everything, is to regain that seriously injured dignity, through the reconstruction of their homes and workplaces, and to revitalise those socio-economic tissues, torn apart by the terrible events that have, not only in a metaphorical sense, strongly shaken them. […]
The economical, technical, and emergency situation has quickly changed some behaviors and today the ICF systems, together with prefabricated wood, are counted among the most promising in terms of benefits induced in the construction phase and performance of the finished building. […]
Finally, I believe that the priority goals of the current post-earthquake reconstruction of 2016, which are rapidity, increase in structural safety and energy efficiency, can be fully satisfied through the use of ICF load-bearing walls system.

“The knowledge of materials”, says Adalbert Stifter, “and their correct way of approaching each other, is the first requirement of every good builder (Baumeister).
The most rich imagination is useless if it lacks such knowledge, since it’s only from them that the constructive fantasy can grow, which is however restrained in the mind of the master builder (Baumesiter), from the implications of the materials that he wants to use.
The built form (Gebaute Form) comes from constant laws and, is always genuine and pure; unlike the architecture (Arkitektur) which lives on the conditioning of time and culture, “Gebaute Form” is in a certain sense timeless and everywhere valid. 1.
The statements by Adalbert Stifter, contained in the “famous” book by Paul Schmitthenner “Built form: variations on a theme”, represent an excellent “openness” to build a reflection on the text written by Cristian Angeli. […]
This book instead (this is its first value), helps us to understand the complexity of a constructive system that, although partially innovative, works on ‘massive’ structures and ‘closed’ forms, in contrast to a common taste that seems to prefer transparent walls, light and with little ‘impact’.
In fact, even to a distractive observer, it’s clear that one of the dominant researches of contemporary architecture is the tendency to create light structures, built with dry assembled materials and technological elements.
In recent years, thanks to the main trade magazines, the trend has been reinforced, to the detriment of heavy structures and in particular of concrete works. Wolfang Bachman, director of the famous German magazine “Baumeister”, believes that the concrete “… in addition to being aged, has a bad reputation”.
The author proposes (here is a second merit of the text), to extend the field of observation, framing the theme, not only on the performance and structural efficiency, but also on the economic and complete management of the site, revaluing and enlightening the innumerable potential of structures with ICF walls […]

I embrace the editorial initiative of Mr. Angeli, engineer, totally dedicated to load-bearing constructive systems of reinforced concrete. These systems were, in fact, the object of studies and researches by the Institute of Construction Engineering of the University of Bologna (where I currently work) since the ‘70s.
The first works were mainly dedicated to the prefabricated reinforced concrete bearing walls and led to the construction (under the design of Prof. Claudio Ceccoli) of numerous civil works that went up to twenty floors in height. In more recent times (starting from the ‘90s of the last century), the studies turned into systems with reinforced concrete load-bearing walls cast in place (able to provide “monolithic” load-bearing structures), first studying their static behavior, and then, starting from the early 2000s, also the seismic behavior. […]
During these years, when there is more awareness of how the problem of seismic resistance of buildings is central not only for the immediate security of the houses in which we live, but also for the value of construction inheritage that we will leave to future generations, an increasingly spreading of these innovative structural systems appears to be very actual and essential. The complete volume, written by Engineer Angeli, is proposed as a fundamental tool for disseminating knowledge, a fundamental condition for constructive diffusion.
