We believe that you have to strike a balance between the materials used, the level of efficiency sought, and the reduction of CO2 emissions (to the extent possible). And of course all of this has to fit within a price that is also sustainable. The goal is for everyone to be able to afford this type of construction. This is why we\u2019re not radical in what we do; we always advise our customers about what they can include in their project depending on their budget<\/p>\n<p>[\/vc_column_text][vc_empty_space height=&#8221;12px&#8221; el_class=&#8221;mobile&#8221;][vc_single_image image=&#8221;35445&#8243; img_size=&#8221;full&#8221; css=&#8221;.vc_custom_1739802094146{padding-bottom: 0px !important;}&#8221; el_class=&#8221;mobile&#8221;][\/vc_column][vc_column width=&#8221;1\/2&#8243; css=&#8221;.vc_custom_1739802086773{background-image: url(https:\/\/rosagres.com\/wp-content\/uploads\/2025\/02\/rosa-gres-arquitectura-casa-sophia-07.webp?id=35444) !important;background-position: center !important;background-repeat: no-repeat !important;background-size: cover !important;}&#8221; offset=&#8221;vc_hidden-sm vc_hidden-xs&#8221;][\/vc_column][\/vc_row][vc_row equal_height=&#8221;yes&#8221; el_class=&#8221;no-gutter&#8221; css=&#8221;.vc_custom_1724245892314{margin-bottom: 0px !important;}&#8221;][vc_column width=&#8221;1\/2&#8243; css=&#8221;.vc_custom_1739802135197{background-image: url(https:\/\/rosagres.com\/wp-content\/uploads\/2025\/02\/rosa-gres-arquitectura-casa-sophia-08.webp?id=35447) !important;background-position: center !important;background-repeat: no-repeat !important;background-size: cover !important;}&#8221; offset=&#8221;vc_hidden-sm vc_hidden-xs&#8221;][\/vc_column][vc_column width=&#8221;1\/2&#8243; css=&#8221;.vc_custom_1724244681035{padding-top: 25px !important;padding-bottom: 50px !important;}&#8221;][vc_empty_space height=&#8221;22px&#8221; el_class=&#8221;no-mobile&#8221;][vc_column_text css=&#8221;.vc_custom_1724248994740{padding-right: 40px !important;padding-bottom: 10px !important;padding-left: 40px !important;}&#8221; el_class=&#8221;no-gutter&#8221;]<\/p>\n<h3 class=\"azul\">WHAT CONCEPTS DID YOU BEAR IN MIND WHEN MAKING THE SWIMMING POOL A SUSTAINABLE CONSTRUCTION?<\/h3>\n<p class=\"texto-\">The swimming pool was always at the heart of the project. We\u2019re in Madrid, and it\u2019s quite common for customers to want to install a pool in their home.

We also ensured that the manufacturer of the material implemented sustainability criteria in its manufacturing processes.

The goal was to find a highly energy efficient purification system that would minimize electrical consumption. To achieve this, we installed a solar pump. It has 3 filtering speeds and allows the pool to be purified with truly reduced consumption.<\/p>\n<p class=\"texto-\">Another important aspect was heating the pool. We wanted to find out how long swimming season could be extended. Not for us, because we barely use it, but in order to give our customers feedback. This is why we installed a heat pump (aerothermal). It is one of the most efficient ones on the market, with an impressive energy efficiency coefficient of performance (COP) of 10.5.<\/p>\n<p class=\"texto-\">Both pieces of equipment, the purifier and the aerothermal pump, always operate with daylight, when we\u2019re generating enough energy with the solar panels, to ensure that they entail no additional cost. All of this is possible thanks to our home automation system, which automatically manages these operations.<\/p>\n<p>[\/vc_column_text][vc_empty_space height=&#8221;12px&#8221; el_class=&#8221;mobile&#8221;][vc_single_image image=&#8221;35451&#8243; img_size=&#8221;full&#8221; css=&#8221;.vc_custom_1739802198947{padding-bottom: 0px !important;}&#8221; el_class=&#8221;mobile&#8221;][\/vc_column][vc_column width=&#8221;1\/2&#8243; css=&#8221;.vc_custom_1739802188459{background-image: url(https:\/\/rosagres.com\/wp-content\/uploads\/2025\/02\/rosa-gres-arquitectura-casa-sophia-09.webp?id=35450) !important;background-position: center !important;background-repeat: no-repeat !important;background-size: cover !important;}&#8221; offset=&#8221;vc_hidden-sm vc_hidden-xs&#8221;][\/vc_column][\/vc_row][vc_row equal_height=&#8221;yes&#8221; el_class=&#8221;no-gutter&#8221; css=&#8221;.vc_custom_1724245892314{margin-bottom: 0px !important;}&#8221;][vc_column width=&#8221;1\/2&#8243; css=&#8221;.vc_custom_1739802248064{background-image: url(https:\/\/rosagres.com\/wp-content\/uploads\/2025\/02\/rosa-gres-arquitectura-casa-sophia-11-1.webp?id=35453) !important;background-position: center !important;background-repeat: no-repeat !important;background-size: cover !important;}&#8221; offset=&#8221;vc_hidden-sm vc_hidden-xs&#8221;][\/vc_column][vc_column width=&#8221;1\/2&#8243; css=&#8221;.vc_custom_1724244681035{padding-top: 25px !important;padding-bottom: 50px !important;}&#8221;][vc_empty_space height=&#8221;22px&#8221; el_class=&#8221;no-mobile&#8221;][vc_column_text css=&#8221;.vc_custom_1724249263250{padding-right: 40px !important;padding-bottom: 10px !important;padding-left: 40px !important;}&#8221; el_class=&#8221;no-gutter&#8221;]<\/p>\n<h3 class=\"azul\">WHAT IS THE DIFFERENCE BETWEEN ENERGY CONSUMPTION AND WATER CONSUMPTION IN A STANDARD HOUSE AND IN CASA SOFIA?
