This is the starting point for considering internal thermal waste unjustified: powering systems that pump cold air into a building that overheats because of an unprotected envelope with green kilowatt-hours is already a failure.<br>When choosing systems for active air conditioning in contexts like these, their sizing is also calculated on summer heat peaks: moments that are certainly frequent but extreme. This means that for the remaining time, the machines will be oversized, resulting in high initial capital expenditure and increased energy consumption.<br>When systems operate under extreme conditions, the stress they experience increases, and a growing energy expenditure does not correspond to the expected cooling performance. At this point, regardless of the energy powering the system, it will be wasted because if the building envelope is not protected, active air conditioning will always be insufficient to create a healthy microclimate.<\/p>\n\n\n\n<h3 id=\"la-nuova-gerarchia-degli-interventi-lefficienza-passiva-come-prerequisito-strutturale\" class=\"wp-block-heading\">The new hierarchy of interventions: passive efficiency as a structural prerequisite<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">For companies, it is therefore appropriate to reverse the perspective and change the approach to the issue: real results are achieved starting precisely from the existing industrial and commercial building, without intervening with structural changes.<br>Passive interventions on the building envelope should in fact be assessed and planned before the installation of any active system, whether this means energy self-production or the replacement of air-conditioning systems, which in some cases even proves unnecessary after the application of high-performance passive solutions.<\/p>\n\n\n\n<h3 id=\"gli-interventi-per-limitare-il-surriscaldamento-di-tetti-e-coperture\" class=\"wp-block-heading\">Interventions to limit overheating of roofs and coverings<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">The heat impact of roofs and coverings undermines the work of photovoltaic panels as well as the performance of the external condensers of industrial chillers. Traditional industrial roofs, generally covered with dark bituminous membranes, absorb the solar spectrum and increase their surface temperature up to 80\u00b0C on the hottest days.<br>Looking specifically at photovoltaic panels, the silicon they are made of, being a semiconductor, loses conversion efficiency when the operating temperature increases.<br>Therefore, when solar radiation reaches its maximum, the photovoltaic system is weakened precisely because of the overheating of the roof surface.<br>To improve this condition, as well as to reduce incoming thermal load and support the work of HVAC systems, the solution is to intervene on the building envelope. Passive technologies act on the properties of the structure, making it an ally in managing surface temperature and therefore indoor temperature.<br>Thermal-reflective coatings transform a roof into a cool roof, a powerful tool for improving control over temperature management without using electricity.<\/p>\n\n\n\n<h3 id=\"la-decarbonizzazione-sono-solo-obbligo-normativo-ma-strumento-di-welfare-attivo\" class=\"wp-block-heading\">Decarbonisation is not only a regulatory obligation, but also an active welfare tool<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Transforming a decarbonisation pathway, as required by regulations, into a strategic lever for energy retrofit and increased well-being for people therefore becomes an element that helps the company build a genuinely green reputation.<\/p>\n\n\n\n<h3 id=\"temperatura-ventilazione-naturale-e-sicurezza-visiva\" class=\"wp-block-heading\">Temperature, natural ventilation and visual safety<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">The indoor microclimate is not just a choice: the employer is first and foremost required to provide a healthy environment for staff working in production areas and offices, as provided for by the Consolidated Law on Safety.<br>Increasing the capacity of active air-conditioning systems, as we have seen, does not always guarantee that the desired temperature will be reached, and it also creates unhealthy indoor environments. Cold air currents generate thermal stratification responsible for discomfort and malaise among people.<br>Indoor climate comfort is achieved when perimeter surfaces are prevented from radiating heat towards people.<br>As regards transparent surfaces, the optical impact of visual glare is another disturbing element, beyond the greenhouse effect they can encourage when they are not protected by solar-control films. Sunlight entering through glazing and skylights creates contrasts that make it difficult to read monitors, while also encouraging distraction.<\/p>\n\n\n\n<h3 id=\"la-velocita-di-intervento-come-variabile-finanziaria\" class=\"wp-block-heading\">Speed of intervention as a financial variable<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">In the traditional evaluation of an investment, namely initial cost and estimated amortisation, another variable must be added, which in the case of production sites, industrial and commercial buildings, takes on significant value: time efficiency.<br>By this we mean the time-related cost of a structural intervention that requires not only technical planning and start-up times, but also a downtime period that interferes with production and internal logistics.<\/p>\n\n\n\n<h3 id=\"serisolar-e-la-tecnologia-passiva\" class=\"wp-block-heading\">Serisolar and passive technology<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">With the installation of passive solutions, the traditional construction site does not exist: the energy retrofit of a building envelope is carried out in a short time and causes no interference with company operations.<br>The application of thermal-reflective coatings on roofs and solar-control films on transparent surfaces is carried out by specialised technicians who work externally and without invading internal production spaces.<br>A further advantage is that energy savings are immediate because there are no technical start-up times, since these are passive solutions: as soon as they are installed, these products reduce the incoming thermal load and help improve work environments.<\/p>\n\n\n\n<h3 id=\"serisolar-ti-aiuta-a-riscrivere-il-bilancio-di-sostenibilita-della-tua-azienda-e-migliorare-il-rating-esg\" class=\"wp-block-heading\">Serisolar helps you rewrite your company\u2019s sustainability report and improve its ESG rating<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">To start reducing your company\u2019s CO2 emissions today, choose a partner that has chosen immediate and measurable results for energy retrofit.<br>Serisolar promotes sustainability not only for its environmental value, but also because it is a valuable tool for companies that choose effective decarbonisation and a clear message to stakeholders: concrete and technologically advanced efficiency.<br>Furthermore, the carbon efficiency of a company\u2019s real-estate assets determines a relevant portion of its <a href=\"https:\/\/serisolar.com\/en\/decarbonisation\/\">ESG<\/a> rating.
