(Background and Purpose) As the economic activity of women increased with rapid industrialization, dual-income families surged. Therefore, the number of cases where the responsibility of childcare was given to daycare centers has increased due to the nuclearized family. As such, the problem of childcare emerged. According to this demand, the number of daycare centers is increasing rapidly despite the physical environment not being properly prepared. Increasing efforts have been made to improve daycare centers, but the importance of creating a natural light environment is often overlooked. The introduction of natural light into the infant care environment is considered a condition that influences the physical and emotional well-being of each recipient, and thus must be considered in the daycare center environment. Therefore, this study seeks to review the effects of natural light on infant development and to suggest a direction of design for the spatial inflow of natural light into children's homes through a domestic and international case analysis. (Method) This study analyzes how natural lighting in indoor childcare areas influences the development of infants, including their ability to exercise, as well as their cognition, emotion, and spatial awareness. Types of natural lighting applied in daycare center interior spaces were classified. First, the visibility by visual element; second, the direction by the method of light inflow; third, the material by the quality of light; and fourth, the brightness by the amount of light. Based on this criteria, three daycare centers in Korea and Japan were selected and a case study was conducted for applied natural lighting design elements to each space. (Results) As a result, both Korea and Japan were found to be good at mining for visual distinctions, but Japan used various sizes, locations, and window heights in their orientation. However, the results show a lack of spatial depth displays through brightness in both Korea and Japan, reflecting poor awareness of the various effects of natural light. (Conclusions) The inflow of natural light into the space of daycare centers is an important factor that positively influences the development of infants and young children. Therefore, it can be seen that natural light is a design factor that must be considered as a basic requirement in daycare center space design. As little importance is placed on natural lighting in the construction of Korean daycare centers, this study provides an opportunity to recognize natural lighting as a significant design element in infant spaces. This study has a limit in its selection of a detached building in daycare center for study; therefore, future research on natural lighting in various types of daycare center spaces is needed. (연구배경 및 목적) 핵가족화와 여성의 사회활동 증가로 맞벌이 가정이 급증함에 따라 가정에서 육아를 전담했던 예전과는 달리 아동 보육을 어린이집에 맡기는 경우가 증가하게 되면서 0세반이 증가하는 등 보육문제가 대두되고 있다. 인간의 발달에 있어 가장 결정적 시기인 0~6세인 영유아 시기의 물리적 보육환경은 매우 중요함에도 불구하고 이러한 수요에 따라 물리적 환경은 제대로 갖추어지지 않은 채 어린이집의 수만 급증하고 있는 실정이다. 이에 점차 어린이집 시설 개선을 위해 많은 노력이 진행되어 왔으나 자연채광을 통한 빛 환경 조성의 중요성에 대해 간과하는 경우가 많다. 영유아 보육 환경에 있어 자연광 유입은 인체의 신경을 자극하여 재실자의 신체와 정서에 좋은 영향을 줄 수 있는 요인으로 반드시 고려되어야 할 조건이라 사료되며 이에 본 연구는 자연광이 영유아 발달에 미치는 영향에 대해 고찰하고 국내·외 사례분석을 통해 어린이집의 공간별 자연광 유입의 공간디자인에 대한 방향 제시를 연구의 목적으로 한다. (연구방법) 본 연구는 실내 보육 공간으로의 자연채광의 특성이 어떻게 영유아 운동능력·인지·정서·공간인지 발달에 영향을 미치는지에 대해 분석한다. 어린이집 실내공간에서 자연채광이 적용된 유형을 분류하였다. 첫째, 지각적 요소에 따른 시각성, 둘째, 빛의 유입 방법에 따른 방향성, 셋째, 빛의 질을 통한 물질성, 그리고 넷째, 빛의 양에 의한 명도성으로 분류하였다. 이를 기준으로 국내 및 일본의 어린이집 각 3곳을 선정하여 공간별 자연채광 디자인 요소 적용 사례연구를 진행하였다. (결과) 그 결과 국내와 일본 모두 시각적 특징를 위한 채광에는 우수했으며 방향성에 있어서도 측창, 천창을 다양하게 사용하였지만 일본의 경우 다양한 크기와 위치, 용도로 채광창을 활용하는 방법에 있어서 차이를 보였다. 반면 국내 및 일본 모두 명도성을 통한 공간의 심도표현이 부족한 결과로 미루어 보아 자연광의 다양한 효과에 대한 인식이 다소 부족하다는 것을 알 수 있었다. (결론) 보육 공간으로의 자연광 유입은 영유아의 운동능력·인지·정서·공간인지 발달에 긍정적인 영향을 미치는 중요한 요소이다. 그러므로 어린이집 공간디자인의 기본적인 요건으로 자연광 유입은 반드시 고려되어야 할 디자인 요소임을 확인할 수 있었다. 국내 어린이집 공간 건립에 있어 자연채광에 대한 중요도가 높지 않은 실정으로 본 연구를 통해 유아 공간에서 자연채광이 중요한 디자인 요소로 인식할 수 있는 계기를 마련한 것에 의의를 두고 있다. 그러나 본 연구에서는 단독형 어린이집을 선정하여 연구를 진행한 한계점을 가지고 있으나 앞으로 이를 바탕으로 다양한 유형의 어린이집 공간에서 자연채광에 대한 공간 연구가 지속적으로 진행될 필요가 있다.

지재훈,최익서 한국공간디자인학회 2022 한국공간디자인학회논문집 Vol.17 No.2

(Background and Purpose) With the rapid development of science and technology, the role and function of light have gradually changed and expanded. In the midst of the changes, city people have come to demand quality lighting associated with natural light in a park, and have come to pursue park lighting that heals and revitalizes tired city life. However, the understanding of the expressive characteristics of natural light is still insufficient, and there are no studies on the use of night lighting related to it. Therefore, the purpose of this study is to specifically propose an application that can secure citizens' emotional stability and a sense of healing, and activate the value of night lighting in the park by directing the night lighting associated with the expressive characteristics of natural light. (Method) It draws the expressive characteristics of natural light by establishing the concept of the value structure by dividing the elements of space into natural and artificial elements through theoretical review on the expressive characteristics of natural light, and by examining the connectivity between park elements and Japanese architect Tadao Ando's philosophical thinking that reflects the modeling of water and light that natural elements have. Taking Nam-san Park in Seoul as an example, it intends to suggest a specific direction for using natural light in various visual modeling. (Results) It has been confirmed that landscape park elements are divided into water, green space, roads, and facilities, which are related to non-materiality and temporality according to light brightness, color temperature, and shadows of nature. It appears as a healing characteristic and an experiential characteristic through the interaction between humans and nature, which is an action factor. In the end, it was confirmed that the expressive characteristics of natural light were developed into human behavior affordance and symbolism by interlocking with non-materiality such as surface, reflection, projection, and distortion and temporality according to the seasons of nature. (Conclusions) In the city park at night, the environment is changed differently depending on the complete utilization of the expressive characteristics of natural light in the space. In particular, it was confirmed that the physical property change of light among the expressive characteristics of it, was expressed as biodynamic characteristic, healing characteristic, and experiential characteristic that are deeply related to the emotional state of citizens, which helps their emotional change, secure emotional stability. It was confirmed that it helps to recreate the existing luminous environment of the park as an experiential space that can bring emotional serenity and vitality away from a more monolithic perspective. It is hoped that various follow-up studies such as a study on the criteria for lighting environment design, will proceed by building a qualitative luminous environment utilizing the expressive characteristics of natural light through this study.

The purpose of this study is to analyze Alva Aalto’s libraries for understanding his efficient induction of natural light. To fulfill this purpose, Alvar Aalto’s thought about library and natural light are examined through his working years and building types. The comparison of his libraries on usage of natural light shows different ways of natural light induction based on different locations and programs of libraries. Similarities and differences of Alvar Aalto’s library architecture have strong relationship to the usage of natural light in libraries because Alvar Aalto himself regard reading as the core function of library and the efficient use of natural light is the main key of reading. In his natural light planning, regional characteristics including environmental factors and programmatic differences act as a basic standard for natural light plan. Especially, altitude of sun and its path, seasonal features affect the induction way of natural light. While conical skylights used at Viipuri library shows the characteristics of universality in Modernism architecture, later libraries presents not only various kinds of pan-shape plan but different ways of inducing natural light in according to appropriate function. From conical skylight to monitor with curved reflection wall make it possible shed diffused light to reading space and this affects to form Alvar Aalto’s organic architecture. As a result, using natural light in Alvar Aano’s library architecture act as the core of forming library concepts and their development.

Humans have adapted and evolved to natural light. However, as humans stay in indoor longer in modern times, the problem of biorhythm disturbance has been induced. To solve this problem, research is being conducted on lighting that reproduces the correlated color temperature(CCT) of natural light that varies from sunrise to sunset. In order to reproduce the CCT of natural light, multiple LED light sources with different CCTs are used to produce lighting, and then a control index DB is constructed by measuring and collecting the light characteristics of the combination of input currents for each light source in hundreds to thousands of steps, and then using it to control the lighting through the light characteristic matching method. The problem with this control method is that the more detailed the steps of the combination of input currents, the more time and economic costs are incurred. In this paper, an LED lighting control method that applies interpolation and combination calculation based on the minimum spectral power distribution information for each light source is proposed to reproduce the CCT of natural light. First, five minimum SPD information for each channel was measured and collected for the LED lighting, which consisted of light source channels with different CCTs and implemented input current control function of a 256-steps for each channel. Interpolation calculation was performed to generate SPD of 256 steps for each channel for the minimum SPD information, and SPD for all control combinations of LED lighting was generated through combination calculation of SPD for each channel. Illuminance and CCT were calculated through the generated SPD, a control index DB was constructed, and the CCT of natural light was reproduced through a matching technique. In the performance evaluation, the CCT for natural light was provided within the range of an average error rate of 0.18% while meeting the recommended indoor illumination standard. 인간은 자연 빛에 적응하고 진화해왔으나 현재는 실내 생활의 비중이 높아짐에 따라 생체리듬 교란의 문제가 유발되었다. 이의 해결을 위해 일출~일몰간 다채롭게 변화하는 자연광의 색온도를 재현하는 조명이 연구되고 있다. 자연광 색온도의 재현을 위해서는 색온도가 다른 다수의 LED 광원을 사용하여 조명을 제작한 후 수백에서 수천 단계의 광원별 인가전류의 조합에 대한 광특성을 측정 및 수집하여 제어지표 DB를 구성하고 광특성 매칭 방법을 통해 조명을 제어하였다. 이러한 제어 방법은 인가전류의 조합 단계를 세밀하게 할수록 많은 시간 및 경제적 비용이 발생한다는 문제가 있다. 이에 본 논문에서는 LED 광원별 최소 분광분포로 보간 및 조합 연산을 수행하여 자연광 색온도를 재현하는 방법을 제안한다. 먼저 색온도가 다른 광원 채널로 구성되고 각 채널별 256단계의 인가전류 제어 기능을 구현한 LED 조명을 대상으로 채널별 5개의 최소 분광분포(Spectral Power Distribution, SPD)를 실측·수집한다. 이후 수집한 SPD를 대상으로 각 채널별 256단계의 SPD를 생성하는 보간 연산을 수행하고, 채널별 SPD의 조합 연산을 통해 LED 조명의 모든 제어 조합에 대한 SPD를 생성한다. 생성된 SPD를 통해 조도와 색온도를 산출하여 제어지표 DB를 구축한 후 매칭 기법을 통해 자연광의 색온도를 재현한다. 성능 평가에서는 실내 권장 조도 기준을 충족하면서도 평균 오차율 0.18%의 범위 내에서 자연광의 시간별 색온도를 제공하였다.

김형경 ( Hyungkyung Kim ),유진형 ( Jinhyung Yu ) 한국공간디자인학회 2015 한국공간디자인학회논문집 Vol.10 No.5

(Background and Purpose) Exhibition space has changed in its role and function in response to rapidly developing social changes. With the gradual transformation from a focus on material wealth to a focus on quality of life, more people are looking for comfortable places to relax and relieve fatigue produced by a complex society. Such spaces have evolved into havens for psychological healing and inspiration. Accordingly, findings of this study suggest that utilizing natural light is important in the design of the exhibition space as a place for psychological healing and inspiration. Natural light can be utilized to produce a comfortable and pleasant environment, with absolute light from the sun as its source for human body rhythms. Natural light is characterized by ever-changing temporality, which can be utilized as the important factor for providing a new atmosphere in an exhibition space that is environmentally friendly. (Method) Through general considerations of natural light and exhibition space, the necessity and role of natural light in exhibition spaces was examined; thus, the relationship between natural light and spatial composition was studied to describe the characteristics of light. An example of utilization of natural light for an exhibition space was found in Peter Zumthor’s Kolumba Museum, which considers light as an architectural language; accordingly, a case study was conducted and the findings were used to present methods for applying the same principles for exhibition spaces. (Results) The characteristics of natural light are classified into brightness, color, and height; furthermore, temporality is caused by the changes in these three characteristics. The psychological emotion that we feel from exposure to light differs depending on the state of light; natural light appears in more varied ways in space through interactions with factors related to spatial composition. Characteristics of light expression in space are sub-classified as expandability, limitation, transparency, immateriality, and directivity, and the utilization of these can be expressed differently depending on the intentions for a space. The Kolumba Museum was planned to feature each spatial characteristic by utilizing these characteristics intentionally. The museum is intended to be a psychological space that influences emotions by allowing visitors to experience various states of light over time, thereby inducing experiences and memories from exposure to natural light in an open structure designed as an exhibition space. (Conclusion) Natural light in an exhibition space is produced with regard to the characteristics of space depending on the utilization method. In an exhibition space, natural light plays a physical role in creating a visual environment with various changes in the state of light depending on the temporality of natural light; thus, natural light has a psychological role because it induces psychological/emotional changes in humans. Natural light influences the general relationship between an exhibition space and the audience; further, it is an important mediating factor in communication between them. Through this study, it is hoped that the importance of natural light in an exhibition space is recognized and that its range of utilization can become wider with subsequent in-depth studies.

태양반사광 규제 입법에 관한 연구

이지헌,이지민 법제처 2023 법제 Vol.703 No.-

최근 빛에 의한 공해인 광해가 사회적 문제가 되고 있다. 인공광(인공조명)에 의한 피해는 2012년 인공조명에 의한 빛공해 방지법이 제정되면서 법률로 규제 및 관리되고 있지만, 자연광에 대해서는 아직까지 아무런 규제 입법이 없다. 자연광(태양광)에 의한 피해 중 직사광에 의한 피해는 자연 현상에 의한 불가항력이나, 반사광(태양반사광)의 경우 건물 축조라는 인위적인 행위가 자연광과 결합한 것으로, 경우에 따라서는 주변 지역의 사람들과 재산에 피해를 일으킬 수 있다. 그러므로 입법을 통해 인공조명에 의한 빛공해 문제를 해결한 것처럼, 태양반사광에 의한 문제 발생을 사전에 방지할 수 있는 입법적 규제가 요구된다. 외국의 일부 국가에서는 현재 태양반사광에 대한 입법적 규제가 이루어지고 있으며, 국내에서도 태양반사광에 의한 문제 발생을 사전에 방지할 수 있는 입법적 규제가 현재 시도되고 있다. 그러나 많은 국가들이 규제 법안들을 제정하지 못한 이유 중 한 가지는 규제의 기준이 될 수 있는 자연 반사광에 의한 빛 반사 피해가 참을 한도를 넘어 생활방해에 이르는 기준을 아직까지 학계에서도 구체화하지 못하였기 때문이다. 또한 건물 재료의 반사율은 자연광의 입사각에 따라 변화하는 등 낮은 반사율을 가진 건물 재료를 사용하였다고 하더라도 자연 반사광의 피해를 전부 방지할 수는 없다. 즉, 반사율만을 기준으로 한 통제는 태양반사광으로 인한 문제 해결에 적합하지 않다. 태양반사광으로 인한 피해는 건축 재료 자체의 반사율이 영향을 미치는 부분도 있으나, 태양의 남중고도 및 태양광의 반사각도 등 주변 환경 및 지리적 위치 등에도 크게 영향을 받는다. 건물의 형태, 방위, 및 높이, 계절, 시간에 따라 자연 반사광의 영향은 달라질 수 있다. 그러므로 빛 반사로 인한 피해의 규제는 일률적인 건물 재료의 반사율 기준이 아닌 건물의 형태와 방위, 그리고 건물의 높이와 인접 건물과의 거리에 따라서 한 건물에서도 각각 다른 반사율 기준이 적용되어야 한다. 따라서 획일적인 입법을 통한 규범적 규제방식보다는 건물의 형태 및 환경조건, 보행자 및 운전자의 피해, 주변 지역으로의 열방사 등 다양한 상황을 고려한 디자인 단계에서의 ‘성능 평가’를 중심으로 규제하는 것이 바람직하다. Recently, light pollution caused by artificial light has become a social issue. Damages caused by artificial light have been regulated and managed by law since the Light Pollution Prevention Act of 2012, but there is still no legislation or regulation regarding natural light. Among the damages caused by natural light (sunlight/solar glare), direct damages caused by direct sunlight are considered unavoidable due to natural phenomena. However, reflected light (reflected solar glare) is a combination of artificial actions such as building construction with natural light and can potentially cause damage to people and properties in surrounding areas. Therefore, legislative regulation is required to prevent problems caused by reflected solar glare in advance, just as the issue of light pollution caused by artificial lighting has been addressed through legislation. Some foreign countries currently have legislative regulations in place for reflected solar glare, and similar legislative regulations are being attempted domestically to prevent issues caused by reflected solar glare in advance. However, one of the reasons why many countries have not been able to enact regulatory bills is that the threshold for damages caused by reflected natural light, which can serve as a basis for regulation, has not yet been concretely defined even within the academic community, as it extends beyond tolerable limits and interferes with daily life. Furthermore, even if building materials with low reflectance are used, the reflectance changes depending on the angle of incidence of natural light, so it is not possible to completely prevent damages caused by reflected natural light. In other words, control based solely on reflectance is not suitable for resolving problems caused by reflected solar glare. Damages caused by reflected solar glare are influenced not only by the reflectance of building materials themselves but also by the surrounding environment, geographical location, solar zenith angle, and solar azimuth angle. The impact of reflected natural light can vary depending on the shape, orientation, height of the building, as well as the season and time. Therefore, regulations on damages caused by light reflection should apply different reflectance standards for each building, depending on its shape, orientation, height, and distance from adjacent buildings, rather than using a uniform standard based on reflectance of building materials. Therefore, it is desirable to regulate through a ‘performance-based requirements’ at the design stage, considering various situations such as the shape and environmental conditions of the building, damages to pedestrians and drivers, and heat radiation to surrounding areas, rather than through uniform legislation and normative regulatory approaches.

대표추세선 기반 자연광 색온도 주기 산출 방법

오승택,김윤지,임재현 한국정보과학회 2022 정보과학회논문지 Vol.49 No.12

The color temperature cycle of natural light helps in promoting good health, such as maintaining the human circadian rhythm. However, although the current lighting technology provides the color temperature during a specific period or the color temperature calculated from characteristics of natural light, a continuous color temperature cycle appearing on the ground cannot be realized. Therefore, this paper proposes a calculation method of natural light color temperature cycles based on the representative trend line to realize the cyclic properties of the color temperature of natural light. First, the color temperature cycle for the sunny day based on each solar term was extracted through the natural light characteristic DB collected through actual measurement. A representative trend line was created through analysis, and then a mean deviation between the representative trend line and color temperature cycle by each solar term was obtained. After calculating the color temperature cycle from the representative trend line from sunrise to sunset for each solar term, a standard of color temperatures of natural light for the solar term/days through shift calculation based on the mean deviation of the color temperature was calculated. The proposed method proved that an accurate color temperature could be calculated within the mean absolute error of 39.8K. 자연광의 색온도 주기는 인체 써캐디안 리듬의 유지 등 건강에 도움을 준다. 그러나 현재 기술은 일정 시간별 색온도나 자연광 특성 기반 연산에 의한 색온도를 제공하지만, 지상에서 발현되는 자연광의 연속적인 색온도 주기를 재현하지는 못하였다. 이에 본 논문에서는 자연광 색온도의 주기 특성을 재현하기 위해 대표추세선 기반 자연광 색온도 주기의 산출 방법을 제안한다. 먼저 실측을 통해 수집한 자연광 특성 DB로부터 각 절기별 맑은 날에 대한 색온도 주기를 추출한 후 분석을 통해 대표추세선을 도출한 후 대표추세선과 각 절기별 색온도 주기와의 평균편차를 구한다. 이후 각 절기별 일출~일몰에 대한 대표추세선 기반의 색온도 주기를 산출한 후 절기별 색온도 평균편차 기반의 이동 연산을 통해 특정 절기/일의 자연광 색온도의 제어 기준을 산출한다. 제안방법에 대한 실험에서는 각 절기별 실측치 대비 평균절대오차 39.8K의 범위 내에서 정확한 색온도 산출이 가능함을 확인하였다.

Good natural lighting and unimpeded views out of a building belongs to the minimum standards required by guidelines for natural, healthy, productive workplace. Attention, however, should be focused not so much on a simple maximization of the natural light available in a space, as on improving the quality of lighting by ensuring as even but intense distribution of illumination in all inner areas. An architectural means of optimal daylight distribution is by using so-called light shelf systems, horizontal shading and redirecting devices. They improve the uniformity of natural light in a space by reducing the level of illumination near the window and redirecting light deeply into the space. In most cases, systems of this kind consist of light-colored, reflecting or mirror elements in the area of the building facade. One problem in selecting and positioning elements of this kind is the facts that ultimately the amount of light available in the facade plane is merely redistributed and reduced a little with each reflection. This paper aims to provide the design guidelines for optimal light shelves based on their geometric and optical characteristics. Their role, that is, a tradeoff between optimal distribution of the daylight and glare control has been evaluated simultaneously. A series of computer simulation deals with the basic geometrical design elements of a commonly used light shelf and sky conditions. As is shown in the results, for best distribution, light shelves should be located as low in a space as possible without causing glare, typically above standing eye level. In addition, more uniformity of light distribution can be improved by extending of the shelf and reflectance of the shelf and higher ceiling height might play a role in increasing the effectiveness of light shelves.

K 노인전문병원의 공간 통합도와 자연광의 상관관계 분석

문선영(Moon, Sun-Young),이현수(Lee, Hyun-Soo) 한국실내디자인학회 2015 한국실내디자인학회논문집 Vol.24 No.2

In case of Senior Hospitals, meticulous care is required in both amount and quality of natural lighting because of the semi-long term residence of patients. Natural lighting has a huge impact on the physical and psychological part for the seniors. Likewise, natural lighting is an important factor considered for hospital design because it can also effect hospitalization period of patients. Research subject was K Senior Hospital which was determined as the courtyard-type building made to provide healing environment through natural lighting. Analysis was performed by dividing the space of K Senior Hospital into Central Treatment Department directly used by patients, Outpatient Department(OPD), Ward Department, Common Use Department. Research was carried out in two ways of integration value analysis using SPACE SYNTAX and illumination intensity analysis using ECOTECT. K Senior Hospital intended to actively let in natural light through courtyard and to make patients exposed to natural light when they walk along the circuit corridor built around the courtyard. This environmental consideration affected the utilization rate of Common Use Department and residence time of patients raising the average of Common Use Department on every floor. As a resuit of this study presenting type C and type D, part of four types of illumination intensity, takes higher percentage of almost every spaces compare to the others therefore K Senior Hospital was designed on the assumption of healing environment composition through natural light. The result of this research would be used meaningfully in the space programming phase of Senior Hospitals in the future. Utilization rate can be adjusted using illumination intensity value in the space that integration rate should be planed to be high. The use(purpose) of space and integration rate can be used as a guideline to set illumination intensity of natural.
