| Summary/Abstract |
The domestic heating sector has a high potential in terms of energy savings and environmental impact. In the present study, an analysis has been carried out on the effect of domestic heating on natural gas (NG) consumption and pollutants emissions. In particular, among various emission pollutants, the nitrogen oxides (NOx) emissions at national level were analyzed in detail. The work was carried out under a collaborative research project between the Italian Ministry of the Environment and Politecnico di Milano.
For the assessment of the national NOx emissions due to residential heating, an inventory of the domestic boilers stock operating in Italy from 1999 to 2010 was made. As from a technological point of view, the precise data about the real composition of national domestic boilers stock were incomplete and not updated, a methodological procedure was developed in order to reconstruct the national domestic boilers stock based on the available technologies and thermal power. According to this scenario, the technological improvement of national boilers stock in the last decade was evaluated in terms of natural gas saving and reduced NOx emissions. Further some discussion has been made on the energy policies for the diffusion of more efficient boilers.

| Summary/Abstract |
Natural Gas (NG) is commonly used for satisfying population needs for heating, domestic hot water production and cooking, particularly in countries where the price of electricity is high. Typically, NG is extensively distributed on urbanized territory and can be exploited by using different technologies. As a consequence, primary energy is usually consumed directly in buildings, allowing high efficiency conversion but also producing pollutants in urban areas. In this paper a comprehensive analysis on NG use in the Italian domestic and tertiary building sector has been carried out, in order to evaluate energy and environmental impact of this fuel on different climatic and geographical contexts, also considering the temporal fluctuation of consumption. The aim of the work is to trace a reliable and up-to-date scenario of NG employment for building heating in Italy, which is one of the EU countries where this source is more widely used.
The study was carried out under the research program "Analysis and evaluation of the current status of the reduction measures of environmental impacts due to heating energy consumption in Italy", funded by the Italian Ministry of Environment.
The data presented are an essential basis for the development of building energy efficiency and consumption rationalization policies.
