I metodi di valutazione rapida degli edifici

Methods of fast evaluation of buildings For many years, works carried out on existing buildings have constituted the principal activity in the building sector, in of the quantity of work carried out and the investments made. Problems related to maintenance/ renovation/ reuse do not only affect buildings erected in the period following the Second World War. Many of these buildings were erected over forty years ago, while others are approaching a forty year history - an age which is commonly considered to severely limit the function efficiency of a buildings, if it has not been subjected to improvement works. Property owners, both private and public, are therefore finding themselves responsible for making diverse and important investment decisions, to bring buildings Up to the date with regulations (safety, accessibility, energy efficiency, sound-proofing etc.), to carry out maintenance work on various parts of building and so on. It is therefore becoming increasingly important to be aware of the technical-functional features of a building, in order to be able to apply the correct strategies when carrying out improvement works. In answer to this problem, various methods have been developed and made available. Despite of their varying objectives and fields of application they have many common features and can be grouped together under the term “methods of fast evaluation”. These methods of fast evaluation are aimed at providing strategies for building work with an efficient use of human and economic resources and time available. They are based on technical, functional and/or economic criteria and the observation and evaluation carried out lead to points being awarded for specific categories, based on a chart of predefined references which may be used in accordance with standardized procedures even on very extensive building surveys. They can be developed to support various stages of works on existing buildings, from planning and scheduling of works to project development and selection of maintenance strategies. The essential requirements for these methods are: user-friendliness; speed of application; the ability to accurately guide to stage of observation-evaluation, guaranteeing unambiguous results; the suitability of the reference model used for the object of the evaluation; the correct balance between the objective of the method/the depth of the observation/the results of the evaluation.
