Abstract
Safety in the workplace has been regulated for years in Italy in a very complete manner and very often it is identified as a set of rules governed by the Legislative Decree of 9 April 2008, n. 81: Consolidated text on health and safety at work, implementation of article 1 of the law of 3 August 2007, no. 123 regarding the protection of health and safety in the workplace. Very often, within the Risk Assessment Document (DVR– Documento di Valutazione dei Rischi), required by law for all companies that have at least one worker, the risks associated with air conditioning and ventilation systems are not always sufficiently taken into consideration, as regards to workers safety at workplace. Numerous studies have shown that microbiological and chemical contamination of the air in confined indoor spaces inside buildings can be attributable to poor hygienic conditions, overcrowding of the premises and/or situations where it is not possible to ensure proper cleaning and maintenance of the aeraulic systems themselves. In this context, this research provides an interesting analysis of some of the main problems inherent in the maintenance of aeraulic systems and their implications, for the parties involved by law, in terms of non-compliance with the provisions of Legislative Decree 9 April 2008, no.81, offering useful ideas for those who want to ensure maximum energy efficiency and healthiness of air conditioning and/or ventilation systems.
Highlights
The European Commission in the last 15 years matured a strong commitment to sustainable development as an indispensable element to guarantee economic prosperity and life quality for people respecting the planet
The “Renovation Wave for Europe” initiative will be based on measures taken with the Clean energy for all Europeans package, notably the requirement for each European Directive (EU) country to publish a long-term building renovation strategy (LTRS), other aspects of the amending Directive on the Energy Performance of Buildings (so called EPBD - (EU) 2018/844), and building-related aspects of each EU country's national energy and climate plans (NECP)
A substantial growth in the usage of climatization, air conditioning and ventilation energy efficient systems is foreseen in the years to come as an indirect consequence on Energy Efficient Buildings, according to the orientation of the European Commission to the sustainable development as an indispensable element to guarantee economic prosperity and life quality for people, respecting the planet
Summary
The European Commission in the last 15 years matured a strong commitment to sustainable development as an indispensable element to guarantee economic prosperity and life quality for people respecting the planet. The “Renovation Wave for Europe” initiative will be based on measures taken with the Clean energy for all Europeans package, notably the requirement for each EU country to publish a long-term building renovation strategy (LTRS), other aspects of the amending Directive on the Energy Performance of Buildings (so called EPBD - (EU) 2018/844), and building-related aspects of each EU country's national energy and climate plans (NECP) This wave of renovation in the building sector, in line with the provisions of the European Directive (EU) 2018/844 on energy efficiency in buildings as a recast of the previous Directive 2010/31/EU (the so-called EPBD, Energy Performance of Buildings Directive), both in the public and in the private sector and in new buildings and existing ones, is possible thanks to the use of highly insulating materials, energy efficient HVAC plant solutions and cutting-edge construction techniques, which ensure that the energy needs of the new buildings tends to be lower and lower, using huge quantities of renewable energy, with obligations already active at EU-27 level, based on the following deadlines: - 01/01/2019: new buildings owned by the public or occupied by public administrations must be nZEB; - 01/01/2021: all other new buildings (practically all private buildings) must be nZEB. In all these cases the correct use of ventilation is extremely important
