The First Report CRESME - SAIE
ENERGY AND BUILDINGS: WHAT IS GOING ON?
How and to what extent the energy efficiency of buildings is changing the market
and observation to quantify the economic impact of technological processes and the dynamics of supply and demand are driving the construction market. And 'This is the main objective of the First Report on ENERGY AND BUILDINGS SAIENERGIA promoted by and implemented by CRESME presented at the opening of Saie 2009.
"The core research - says the CEO of CRESME Lorenzo Bellicini - is to analyze the market that directly impacts the building and construction sector. We have set ourselves a number of questions and the answers we sought. For example, weighs on the market for energy-saving closures transparent? About 6 million windows made in 2009? Glazed systems, systems of screening? As for closures on the mat? About 46 million square feet of walls to be carried out despite the crisis? We have a specific section devoted to the effects on production and market of air conditioning, heating and cooling. We estimate that in 2009 you are just replacing some 900,000 persons and facilities which we have analyzed the changes in the choice of boilers or new plants and how these choices alter the energy performance. Special attention we devoted to the automation and control and to meet alternative energy sources to oil ...."
And what are the results being achieved in new construction and upgrading of existing assets?
"Italy is a country lagging behind compared to the" climate package "based on the European Union aimed at saving 20-20-20 a progressive reduction of CO2 emissions, so that we were condemned to pay penalties of € 550 million. And we know that the greatest contribution to the savings and reduction of CO2 emissions, potentially comes from its energy recovery work on the park's existing buildings. Suffice it to only the example of the retrofit retained at the time of ordinary and extraordinary maintenance, which would be able to save 57.1 GWh in 2016 and already almost 83.8 GWh in 2020, taking into account only the residential and tertiary sectors. A result which accounts for almost 64% of total energy savings assumed in the year. "
The Report describes the potential savings of different technological solutions and design, to understand and assess to what extent the different construction methods are able to get closer to emerging from the most recent and thorough analysis that highlight how an optimal exposure of the building will save around 3% of energy consumption. Again an example helps to understand the great potential existing in the industry and that the solutions are actually at hand: a cost of 380 € / sqm for the purchase of thermal insulating windows you are able to reduce by 18% Co2 emissions. An investment that, for the purchase of glasses "low-emissivity", which pays for itself in 10 years.
Some important effects of the measures taken steps to see. For example, the effect of the introduction of the "tariff" has resulted in the production of energy from solar photovoltaics, although still limited, an increase of 395% from 39 GWh to 139 GWh.
Reduction of CO2 delays Italy
The "climate package" of the European Commission 20-20-20 (20% of consumption covered by renewable energy, -20% greenhouse gas emissions, improvement of 20% energy efficiency) to be implemented by 2020 for Italy provides a reduction of -14% of the CO2 emissions compared to 2005 and total production from renewable sources 17% of final energy consumption. The reduction greenhouse gas emissions must include the 20% by energy-intensive sectors (ETS), but also the 13% of non-ETS sectors. With this measure, it is investing an obligation to reduce emissions even families (consumption habits) and buildings (production, consumption and efficiency). Already this year, Italy is in default with respect to emissions and must pay fines to the EU 555 million euros. Also in the consumption of renewable energy Italy appears to lag behind the target of 17% in 2020 because, in 2006 stood at 7% and 2008 is estimated to be placed around 8, 5%. Only with respect to electricity consumption, Italy is located in a less difficult because in 2008 consumed 24.0% of renewable energy (including manufactured and imported) on a target that is expected to about 30% in 2020.
