Introduction
Aicha Diakite is a researcher and lighting engineer working in the field of daylighting, sustainable urban planning and environmental modelling. She is currently working at the Chair of Lighting Technology, Technische Universität Berlin (Germany). Her doctoral research proposes spectral sky models to enable the integration of new daylighting strategies into the design of urban structures that support people’s well-being. Aicha received several awards for her work including the H.-J.-Helwig-Prize 2014 by the German Society of Lighting Technology, the Hans-Peter-Willumeit-Award by the Center of Human-Machine Systems and the Clara-von-Simson-Prize honoring women in science and engineering by the TU Berlin.

Article
This paper analyses the forecast accuracy of current state-of-the-art, data-driven, spectral sky models. The aim is threefold: (i) to determine the forecast accuracy of existing spectral sky models based on a large dataset of spatially, spectrally and temporally resolved measurements, (ii) to investigate the practical implications of spectral forec...
Article
Full-text available
Spectrally and spatially resolved information on daylight is critically important when planning for non-image forming (NIF) responses. Nevertheless, the availability of such data is scarce given the high initial costs and complex on-site maintenance of high-end spectral measurement devices. The CIE (Commission Internationale de l’Éclairage) reconst...
Article
This paper introduces a novel approach to integrate orientation-dependent spectral properties of daylight in urban planning. These spectral characteristics of light at façades are represented in spectral daylight potential diagrams (SDPDs). The applicability of SDPDs is subsequently discussed in the context of non-image forming (NIF) effects, compa...
Technical Report
Full-text available
This technical report deals with the current state of the art in the field of spectral measurements and models of daylight. The presented document is a result of joint work conducted by members of the IEA SHC Task 61 / EBC Annex 77, Subtask C3. It provides an overview of: (i) daylight sites conducting spectral (radiance, irradiance) measurements (i...
Article
This paper presents selected results from the first stage of DAYKE (Daylight Knowledge in Europe), a 3-phase project that investigates the knowledge on daylighting in buildings among architecture students and practitioners across Europe. Subjective judgements from 561 students from 8 architecture universities in the EU, collected through two survey...
Article
Full-text available
Research indicates that spectral distribution and the direction of the light received at the eye are relevant parameters in studies looking into non-image-forming effects. Nonetheless, lighting conditions are often described with vertical illuminance at the eye and correlated color temperature only, both of which are integral measurements that are...
Conference Paper
Two independent surveys were conducted in 2017 and in 2018 among architecture students across Europe to investigate their knowledge on daylighting and the impact of that knowledge on the visual perception of daylit spaces. A total of 600 responders were involved. This paper presents findings from the second survey, which was distributed in six Euro...
Book

Energy efficient lighting is said to be one of the most cost-effective approaches to save energy and reduce C02 emissions. In order to stimulate the application of lighting retrofits of good quality, IEA Task 50, Subtask B “Daylighting and Electric Lighting solutions” has looked into the assessment of existing and new technical retrofit solutions i...

Integrated Solutions for Daylighting and Electric Lighting: From component to user centered system efficiency Overview Lighting accounts for approximately 19% of the global electric energy consumption. Research and development in the field of energy efficient lighting techniques encompassing daylighting, electric lighting and lighting controls potentially can contribute significantly to reduce this demand. Nonetheless, growing economies, higher user demands for quality lighting and rebound effects as a result of low priced and more versatile electric lighting – “more for less” – lead to an absolute increase of the worldwide lighting energy consumption. More light is used, less consciously. The lighting as well as the façade market have seen significant technological developments and strong growth in the past decade - where nevertheless both market sectors still act mainly completely independent of each other, leaving out big chances for better user centred and at the same time efficient systems. Research and developments in the field of energy efficient lighting techniques that integrates daylighting, electric lighting and lighting controls is thus needed. The ultimate goal is employing this integrated approach and bringing these techniques to the market which can reduce significantly worldwide electricity consumption and CO2 emissions. These activities will therefore be in line with several different governmental energy efficiency and sustainability targets.
Project
The main goal of the project is the development of data-driven spectral sky models for accurate integration of daylight in the design of healthy urban structures. The spectral sky models reveal the orientation-dependent spectral characteristics of daylight and are derived from the spatially resolved spectral measurements collected at the daylight measuring station of the Technische Universität Berlin, one of the few measuring sites worldwide gathering this kind of data. The spectral sky models will subsequently be used as a basis for a large-scale parameter study on the impact of building orientation, existing daylighting conditions and urban obstruction proprieties on the spectral potential of daylight. The spectral characteristics of daylight on facades will be displayed in spectral daylight-potential diagrams. The outcomes of the parameter study are to be shared with urban planners and lighting designers, in order to encourage greater awareness of the potential of daylight and help create new lighting design strategies that support people’s well-being.
Project
The project aims to quantify the level of knowledge of daylighting among professionals and university students in the building sector.
