How can shading devices reduce energy consumption in buildings?

The statement "Shading devices can be classified into two main types: external & internal." isn't strictly true. There is a third option, which is where the shading device is incorpoated within the cavity of an insulated glass unit - the option that Okalux Glastechnik have been producing in various forms for over 5 decades. The benefit of this is the reduction in installation time, as well as the long term saving in maintenance costs. With no dirt ledges as you get with a traditional Brise Soleil the only maintenance required is cleaning of the glass. Okatech, with an expanded metal in the unit, achieves light transmission & g values that vary with the suns angle. A g as low as 8% can be achieved for high sun angles, reducing cooling loads

Shading devices act as building sunblock, blocking unwanted heat gain and saving energy in multiple ways: Reduced cooling needs: By blocking sunlight, they lower indoor temperatures, decreasing reliance on air conditioning. Optimized daylighting: They control sunbeams, allowing natural light without glare, minimizing use of artificial lighting. Improved comfort: Cooler spaces lead to increased occupant comfort and productivity. Lower energy bills: Savings on cooling and lighting translate to reduced energy consumption and cost. Think of them as your building's sunglasses, keeping it cool and comfortable while saving energy

SOIL has enormous potential for carbon capture and storage. This is one of the ecosystem services that NATURE-BASED SOLUTIONS demand. This is noticeable in the quality of biodiversity it supports. - Based on my experience, it is essential to analyze soil taxonomy, ecological functions, climatic variations, and the quality of biodiversity, among other aspects, very well. - A great utility of this ecosystem service is in soil bioengineering, which contributes to this ecological function.

Shading devices reduce energy consumption in buildings by blocking direct sunlight, reducing cooling loads, improving occupant comfort, extending the lifespan of materials, controlling passive heating, and integrating with building design.

External shading devices block the direct sunlight that penetrates glass, but more critically heats the entire surface of a structure. This can be not just in the form of overhangs, but decorative, detached walls. Accommodating plant life can enhance the shading capabilities as well as increase aesthetics and consume pollutants. Interior shading typically takes the form of window covers, but also includes insulation interior to the wall structure.

Shade-producing devices, like blinds and louvers, have two advantages: they increase occupant comfort and energy efficiency. When shade is strategically positioned, solar heat gain is reduced, reducing the need for excessive cooling. This improves productivity and well-being by ensuring a constantly comfortable indoor atmosphere while also saving electricity. Furthermore, by optimizing natural lighting, these gadgets minimize glare and lessen the need for artificial lighting. Their incorporation into architectural design improves both the building's usability and aesthetic appeal. Shading devices, in short, are essential to sustainable construction practices because they combine energy efficiency with comfort and aesthetics.

Beyond the obvious effects of reducing the need for interior air conditioning, shading, namely exterior, can reduce sun damage to exterior coatings. The thermal impacts on structural materials can also be reduced with exterior shading, with more heat sensitive items in the interior of the structure being protected with interior insulation.

O sombreamento é uma das mais importantes estratégias, dado o clima brasileiro, o calor proveniente do sol e a frequente necessidade de bloqueá-lo. Em climas quentes, pode ser utilizado conjuntamente com medidas de resfriamento passivo, além de colaborar com a eficiência energética, enquanto, em climas frios deve ser aplicada de modo bastante planejado, de forma que n?o impe?a o aquecimento da edifica??o nos meses de menor temperatura, colaborando também com a eficiência energética, evitando o uso de aquecedores.

Generally, shading devices are used to protect inner spaces from direct solar gain through openings, windows and large glazed surfaces. Different climatic region needs different configuration of shading devices. Buildings in hot-humid climate need to reduce solar radiation and sunlight penetration into the building.

While there may be upfront costs associated with the installation of shading devices, the reduced energy consumption over the building's lifespan can result in substantial financial benefits.

Já que a posi??o do sol em rela??o ao planeta se altera ao longo do ano, o projeto de sombreamento deve ser feito em conjunto com a carta solar. A carta solar permite que o dispositivo de sombreamento seja projetado de forma que bloqueie o sol nos momentos onde ele é indesejável (quando está muito quente) e que entre nos momentos em que é desejável (quanto está frio). O horário do dia em que se tenta bloquear os raios solares também é importante de se definir: nas fachadas norte e sul, esses raios s?o mais fortes quando o sol está diretamente em cima. Portanto, um brise horizontal, como um terra?o ou um beiral, é efetivo para proteger a janela.

Interior or exterior? Exterior will keep sunlight from penetrating the glass (which itself can have shade characteristics). Unless removable, n a cold climate, no heat from the sun to the interior. You can operate interior shading to protect anything that fades and still get the benefits of sunlight for lighting and morale.

Ao selecionar dispositivos de sombreamento para um edifício, é essencial considerar fatores como clima, geometria solar, orienta??o e geometria do edifício, fun??o e ocupa??o. A exposi??o à radia??o solar na fachada e no telhado, as preferências de conforto térmico e visual dos usuários, e as propriedades térmicas e ópticas, durabilidade e manuten??o dos materiais e cores s?o determinantes. Além disso, a viabilidade e custo dos dispositivos devem ser ponderados com base na complexidade, tamanho e método de instala??o.

Uma coisa que achei muito útil e interessante é que o sombreamento externo deve sempre considerar o custo de instala??o, a durabilidade e o custo de manuten??o. Principalmente, em edifícios altos a manuten??o desses dispositivos geralmente é muito complexa, gerando um custo elevado de manuten??o. Logo, um equipamento bem projetado e com maior durabilidade deve ser sempre ponderado.

Shading devices can reduce building footprint, in terms of CO2 emissions and energy consumption, where these devices will contribute to serve building occupants efficiently and in smart way based on our needs, such as making use of sunlight and natural ventilation.

Brises verticais: Bloqueiam o sol de manh? e tarde nas fachadas leste e oeste. Brises horizontais: Bloqueiam o sol quando está diretamente em cima, durante o dia, por exemplos nas fachadas norte e sul. As dimens?es de proje??o dos brises afetar?o os horários do dia durante os quais a janela está protegida de entrada de sol, ou seja, sombreamento. Sombreamento interno: Dispositivos de sombreamento internos, como cortinas e persianas, podem ser usados para controlar a entrada de radia??o solar em ambientes internos. No entanto, s?o muito menos eficientes do que dispositivos colocados na área externa, isso porque quando expostos ao sol, se aquecem e emitem calor diretamente para o ambiente, ou seja, n?o barram, de fato, a chegada da radia??o.

And to think, within the last week on LinkedIn, the solar energy industry took an environmental hit for not being green because solar panels reflect heat.

Consider reflective coatings as part of the heat management strategy. This is actually an ancient strategy that is appearing again on homes in high sunlight areas in the U.S. Southwest. A house may be any color on shaded sides, but white or very light pastels on sun facing sides, and with very reflective exterior paint.

Shading devices, such as awnings, louvers, or external blinds, can significantly reduce energy consumption in buildings by minimizing solar heat gain and glare. By strategically positioning these devices, they block direct sunlight from entering windows during peak hours, reducing the need for air conditioning and artificial lighting. This helps maintain a comfortable indoor temperature and lighting level, consequently lowering cooling and lighting energy requirements. Additionally, shading devices can prolong the lifespan of HVAC systems by reducing their workload, resulting in further energy savings and maintenance cost reductions.
