However, it is considered an outdated system that, in addition to taking up space, requires constant maintenance and, consequently, generates high operating costs.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">However, reality shows that many condominium owners and administrators <strong>They are unaware of the real benefits of transitioning to natural gas.<\/strong>. In this way, they end up maintaining an inefficient infrastructure which, consequently, compromises both the <strong>security<\/strong> as for <strong>operational economy<\/strong> of the building.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">In this article, therefore, you will understand <strong>Why switching to natural gas is a strategic decision.<\/strong>, In addition to understanding the costs involved, the return on investment, and how the transition occurs in practice, further information will be presented. <strong>Real-life examples of buildings in Santa Catarina<\/strong> who have already made this change. In the end, you will have all the information you need to make a technically, economically, and strategically sound decision.<\/p>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<h2 class=\"wp-block-heading\">What is natural gas?<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Natural gas (NG) is a fossil fuel composed primarily of methane (CH\u2084). It is extracted from underground reservoirs and subsequently distributed to consumers via a pipeline. <strong>underground pipeline network<\/strong>, operated by local concessionaires, such as Celesc, in Santa Catarina.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Unlike LPG, which depends on cylinders and frequent replacements, natural gas is supplied. <strong>continuously<\/strong>, The water is supplied directly to the building, similar to water and electricity supply. Therefore, the consumer only pays for the volume actually consumed.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Furthermore, natural gas is lighter than air. Therefore, in case of a leak, it tends to rise and dissipate quickly. In addition, its operating pressure is lower than that of LPG, which makes the system... <strong>naturally safer<\/strong>. As a result, there is no need for storage, delivery scheduling, or risk of shortages.<\/p>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<h2 class=\"wp-block-heading\">LPG vs Natural Gas: A Complete Comparison<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Before making any decision, it is essential to conduct a technical, economic, and operational comparison between the two systems.<\/p>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<h3 class=\"wp-block-heading\">Operating Cost<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Firstly, the monthly cost is one of the factors that most impacts the decision.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Natural gas:<\/strong><\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Average value in SC: R$ 0.80 to R$ 1.20 per m\u00b3<\/li>\n\n\n\n<li>Average monthly consumption per apartment: 25 to 35 m\u00b3<\/li>\n\n\n\n<li>Estimated monthly cost: R$ 20 to R$ 42<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>LPG (Bottled Gas):<\/strong><\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Price of a 13 kg gas cylinder: R$ 60 to R$ 80<\/li>\n\n\n\n<li>Average duration: 15 to 20 days<\/li>\n\n\n\n<li>Estimated monthly cost: R$ 90 to R$ 160<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">Consequently, the monthly savings per apartment varies between <strong>R$ 48 and R$ 138<\/strong>. Therefore, in a building with 30 units, the annual savings can reach between <strong>R$ 17.280 and R$ 49.680<\/strong>, This reinforces the financial viability of the change.<\/p>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<h3 class=\"wp-block-heading\">Security<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Besides cost, security is a determining factor, especially in multi-family buildings.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Advantages of Natural Gas:<\/strong><\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Lower operating pressure, reducing risks.<\/li>\n\n\n\n<li>Lower probability of explosions<\/li>\n\n\n\n<li>Continuous system, no need to handle cylinders.<\/li>\n\n\n\n<li>Constant monitoring by the dealership.<\/li>\n\n\n\n<li>Direct compliance with current technical standards.<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Risks of LPG:<\/strong><\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>High blood pressure<\/li>\n\n\n\n<li>Risk during gas cylinder exchange<\/li>\n\n\n\n<li>Need for proper storage<\/li>\n\n\n\n<li>More frequent periodic inspections<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">In this way, industry statistics indicate that <strong>Buildings using natural gas have up to 801% fewer gas-related accidents.<\/strong>, when compared to those that use LPG.<\/p>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<h3 class=\"wp-block-heading\">Physical Space<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Another important point is making the most of the available space in the condominium.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Natural gas:<\/strong><\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>It only needs a wall connection.<\/li>\n\n\n\n<li>Eliminates the need for a central gas supply.<\/li>\n\n\n\n<li>It allows for the reuse of the previously occupied area.<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>LPG:<\/strong><\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Requires a central gas system with multiple cylinders.<\/li>\n\n\n\n<li>Minimum safety distances are required.<\/li>\n\n\n\n<li>It can occupy between 20 and 50 m\u00b2 in small condominiums.<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">In practice, therefore, a condominium with 30 units can free up space equivalent to <strong>1 or 2 parking spaces<\/strong>, which, in turn, can be converted into common or commercial areas.<\/p>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<h3 class=\"wp-block-heading\">Convenience in Everyday Life<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">From an operational standpoint, the impact on residents&#039;

Contudo, trata-se de um sistema considerado ultrapassado, que, al\u00e9m de ocupar espa\u00e7o, exige manuten\u00e7\u00e3o constante e, consequentemente, gera custos operacionais elevados. Ainda assim, a realidade mostra que muitos propriet\u00e1rios e administradores de condom\u00ednios desconhecem os benef\u00edcios reais da transi\u00e7\u00e3o para o g\u00e1s natural. Dessa forma, acabam mantendo uma infraestrutura ineficiente que, por consequ\u00eancia, compromete tanto a seguran\u00e7a quanto a economia operacional do edif\u00edcio. Neste artigo, portanto, voc\u00ea entender\u00e1 por que migrar para o g\u00e1s natural \u00e9 uma decis\u00e3o estrat\u00e9gica, al\u00e9m de conhecer os custos envolvidos, o retorno do investimento e como ocorre a transi\u00e7\u00e3o na pr\u00e1tica. Al\u00e9m disso, ser\u00e3o apresentados casos reais de edif\u00edcios em Santa Catarina que j\u00e1 realizaram essa mudan\u00e7a. Ao final, assim, voc\u00ea ter\u00e1 todas as informa\u00e7\u00f5es necess\u00e1rias para tomar uma decis\u00e3o t\u00e9cnica, econ\u00f4mica e estrategicamente fundamentada. O que \u00e9 G\u00e1s Natural? O g\u00e1s natural (GN) \u00e9 um combust\u00edvel f\u00f3ssil composto principalmente por metano (CH\u2084). Ele \u00e9 extra\u00eddo de reservat\u00f3rios subterr\u00e2neos e, posteriormente, distribu\u00eddo aos consumidores por meio de uma rede de tubula\u00e7\u00f5es subterr\u00e2neas, operada por concession\u00e1rias locais, como a Celesc, em Santa Catarina. Diferentemente do GLP, que depende de botij\u00f5es e trocas frequentes, o g\u00e1s natural \u00e9 fornecido de forma cont\u00ednua, diretamente ao edif\u00edcio, de maneira semelhante ao fornecimento de \u00e1gua e energia el\u00e9trica. Assim, o consumidor paga apenas pelo volume efetivamente consumido. Al\u00e9m disso, o g\u00e1s natural \u00e9 mais leve que o ar. Portanto, em caso de vazamento, ele tende a subir e se dissipar rapidamente. Somado a isso, sua press\u00e3o de opera\u00e7\u00e3o \u00e9 menor que a do GLP, o que torna o sistema naturalmente mais seguro. Como resultado, n\u00e3o h\u00e1 necessidade de armazenamento, agendamento de entregas ou risco de desabastecimento. GLP vs G\u00e1s Natural: Compara\u00e7\u00e3o Completa Antes de qualquer decis\u00e3o, \u00e9 essencial realizar uma compara\u00e7\u00e3o t\u00e9cnica, econ\u00f4mica e operacional entre os dois sistemas. Custo Operacional Primeiramente, o custo mensal \u00e9 um dos fatores que mais impactam a decis\u00e3o. G\u00e1s Natural: GLP (G\u00e1s de Botij\u00e3o): Consequentemente, a economia mensal por apartamento varia entre R$ 48 e R$ 138. Dessa forma, em um edif\u00edcio com 30 unidades, a economia anual pode atingir entre R$ 17.280 e R$ 49.680, o que refor\u00e7a a viabilidade financeira da mudan\u00e7a. Seguran\u00e7a Al\u00e9m do custo, a seguran\u00e7a \u00e9 um fator determinante, especialmente em edifica\u00e7\u00f5es multifamiliares. Vantagens do G\u00e1s Natural: Riscos do GLP: Dessa maneira, estat\u00edsticas do setor indicam que edif\u00edcios com g\u00e1s natural apresentam at\u00e9 80% menos acidentes relacionados a g\u00e1s, quando comparados \u00e0queles que utilizam GLP. Espa\u00e7o F\u00edsico Outro ponto relevante \u00e9 o aproveitamento do espa\u00e7o dispon\u00edvel no condom\u00ednio. G\u00e1s Natural: GLP: Na pr\u00e1tica, portanto, um condom\u00ednio com 30 unidades pode liberar espa\u00e7o equivalente a 1 ou at\u00e9 2 vagas de garagem, que, por sua vez, podem ser convertidas em \u00e1reas comuns ou comerciais. Conveni\u00eancia no Dia a Dia Do ponto de vista operacional, o impacto na rotina dos moradores tamb\u00e9m \u00e9 significativo. G\u00e1s Natural oferece: GLP exige: Assim, o g\u00e1s natural proporciona maior previsibilidade e conforto no dia a dia. Vantagens Estrat\u00e9gicas do G\u00e1s Natural em Edif\u00edcios Al\u00e9m da compara\u00e7\u00e3o direta com o GLP, o g\u00e1s natural oferece benef\u00edcios estrat\u00e9gicos de m\u00e9dio e longo prazo. Valoriza\u00e7\u00e3o do Im\u00f3vel Estudos imobili\u00e1rios indicam que edif\u00edcios com g\u00e1s natural apresentam valoriza\u00e7\u00e3o entre 5% e 8% no valor de mercado. Por exemplo, um apartamento avaliado em R$ 500.000 pode alcan\u00e7ar entre R$ 525.000 e R$ 540.000 ap\u00f3s a moderniza\u00e7\u00e3o do sistema. Dessa forma, o mercado passa a enxergar o im\u00f3vel como mais moderno, seguro e eficiente. Redu\u00e7\u00e3o de Custos Operacionais Quando se analisa o condom\u00ednio como um todo, os n\u00fameros tornam-se ainda mais expressivos. Custo GLP G\u00e1s Natural Economia G\u00e1s mensal R$ 2.700 R$ 600 R$ 2.100\/m\u00eas Inspe\u00e7\u00e3o anual R$ 1.500 R$ 300 R$ 1.200\/ano Manuten\u00e7\u00e3o da central R$ 800\/m\u00eas R$ 0 R$ 9.600\/ano Total anual R$ 39.300 R$ 7.200 R$ 32.100 Portanto, ap\u00f3s o primeiro ano \u2014 no qual ocorre o investimento inicial \u2014 toda a economia passa a ser recorrente e previs\u00edvel. Sustentabilidade Al\u00e9m dos ganhos financeiros, o g\u00e1s natural \u00e9 30% a 40% menos poluente que o GLP. Assim, contribui para: Por esse motivo, condom\u00ednios que buscam certifica\u00e7\u00f5es ambientais encontram no g\u00e1s natural um aliado estrat\u00e9gico. Custos de Implementa\u00e7\u00e3o Naturalmente, a principal d\u00favida refere-se ao investimento necess\u00e1rio para a mudan\u00e7a. Investimento Total \u2013 Exemplo (30 unidades) Fase Valor Projeto e licen\u00e7as R$ 5.000 Obras civis R$ 75.000 Materiais e equipamentos R$ 25.000 Testes e certifica\u00e7\u00e3o R$ 3.000 Total R$ 108.000 Por unidade R$ 3.600 Retorno do Investimento Considerando uma economia anual m\u00e9dia de R$ 32.100, o retorno do investimento ocorre em aproximadamente: R$ 108.000 \u00f7 R$ 32.100 = 3,4 anos Ap\u00f3s esse per\u00edodo, portanto, a economia passa a ser l\u00edquida e recorrente por d\u00e9cadas. Considera\u00e7\u00f5es Finais Em resumo, a migra\u00e7\u00e3o de GLP para g\u00e1s natural n\u00e3o \u00e9 apenas uma moderniza\u00e7\u00e3o, mas sim uma decis\u00e3o estrat\u00e9gica.
