The future of construction lies in sustainability. Energy efficiency in buildings is a necessary reality, since most of the energy consumption in our cities occurs indoors , around a fifth of the total. Furthermore, it is . Estimate that in Spain there are more than 13 million homes that do not meet the minimum efficiency in energy consumption. For this reason, starting in 2020 it will be mandatory that all constructions seek to be Almost Zero Consumption Buildings . However, how do we achieve more efficient buildings? On the one hand, thanks to Almost Zero Consumption Building (ECCN), in just over a year there will be no nee to worry about the construction sector. By then, European-wide measures will be implemente so that new construction achieves homes and professional environments that meet the following.
How to ac hieve energy efficiency in buildings?
Conditions: Ecological lighting . Beyond low-consumption light bulbs, ECCN must seek better use of sunlight so as not to depend on artificial solutions. Passive cooling in summer. Heat must be preventd from Hong Kong Phone Number List seeping into the rooms in the warmer months. To do this, you can have ventilatd covers and other options that do not require the use of air conditioning units. Thermal insulation to prevent the entry of cold in winter. The tightness of the buildings means that in the colder months the use of heating is not necessary. Photovoltaic panels on the roof to supply other air conditioning systems, if necessary at specific times. Mechanical ventilation systems . They are key to energy efficiency in buildings , since a third of the consumption admitte in this type of buildings is ventilation. Double flow ventilation.
Solutio ns are capable
Addition to guaranteeing health in the rooms, offering heat in winter and cooling in summer thanks to their exchanger. Reducing spending on lighting and also air conditioning is the most important challenge of Argentina phone number list energy efficiency in Almost Zero Consumption Buildings . However, this is achieve with a comprehensive construction plan. And, furthermore, the big problem comes when taking into account all the homes and places that are in poor conditions base on their energy efficiency . This is where a new type of rehabilitation would come in focuse on improving the way buildings manage consumption. Efficient rehabilitation is somewhat more expensive than implementing the same measures when constructing a new building, but then you can save significantly on utility bills, so.
