|“Colour preference-based LED lighting” – The current color quality designs of LED lighting products are based on the current standards for chromaticity specifications (e.g., ANSI C78.377) and color rendering metric (CIE CRI). However, it has been known that lights with chromaticity below the Planckian locus and lights with color-enhancing characteristics (larger gamut area) are often preferred. It is also experienced that too much color saturation has negative effects. Vision experiments were conducted at NIST recently using NIST Spectrally Tunable Lighting Facility simulating typical interior lighting environment, to determine the most preferred level of chromaticity shifts from the Planckian locus and the most preferred level of chroma increase of objects for interior lighting situations. The results showed that the chromaticity much outside the range of ANSI C78.377 (Duv≈ -0.015) and lights slightly enhancing chroma (DC ≈ +5, Ra≈ 85) are most preferred on the average of ≈20 subjects. These results indicate that the current standards are unduly restricting color quality design, prohibiting possibilities of more preferred lighting products. Additional standards are needed to allow development of such variation of lighting products based on color quality preference.|
|Assoc. Professor Inês Azevedo’s research interests lie at the intersection of environmental, technical, and economic issues, such as how to address the challenge of climate change and to move towards a more sustainable energy system. Dr. Azevedo tackles complex problems in which traditional engineering plays an important role but cannot provide a complete answer. Dr. Azevedo has also been working on assessing how specific policies will shape future energy systems, especially in a carbon-constrained world.|

|“Transitions in Museum Lighting Design”Abstract: Through a concise appraisal of existing museum lighting techniques Transitions in Museum Lighting Design looks at how the advent of new and emergent technologies is opening the way for more innovative approaches to lighting design. As architecture is called upon to reconcile conflicting philosophies, so too must natural and artificial lighting design focus on the changing relationships between museum architecture, artefacts and the external environment, cultivating a broader public understanding of the role of light in how we interpret our surroundings.|

|“Light and colour in the built environment” – This presentation covers how to describe the effect light will have on an environment: its atmosphere, faithfulness in portrayal of surfaces, making food appetising, making people look healthy and of course the foundation functional needs. It will detail core technical parameters: colour appearance, colour consistency and colour rendering, with a breakdown of the metrics involved and in each case some unique demonstrations, for example of gamut area on fabrics – illustrated below. Each attribute will then be discussed in terms of its application relevance from the standpoint of Interior Designers and Lighting Designers. Using core end-user needs like brand, emotion, functionality and environmental fit, examples will be given and explained in diverse applications from residential to galleries to retail to offices to decorative outdoor.|

|“The potential health issues of solid-state lighting” – The International Energy Agency’s (IEA) Energy Efficient End-Use Equipment (4E) Annex on Solid-State Lighting (SSL) works to assist governments of member countries in promoting SSL as an effective means to reduce energy consumption worldwide. Between 2011 and 2014, the SSL Annex reviewed all of the major health-related literature associated with LED lighting. This presentation follows the publication in September 2014 of the results. The biological and health effects of SSL products on humans will be detailed: glare issues, photobiological effects caused by the optical radiation on the eye and the skin, flickering phenomena and non-visual effects of light, such as the effects on circadian rhythms and the biological clock. While lighting standards and practices have recently evolved to include some health-related requirements, the author will explore the uncertainties surrounding both the undesired and beneficial health effects of the human exposure to SSL products.|

|“The results of quality testing of residential LED lamps” – The EU-regulations on Eco-design and Labelling for lighting provide an essential framework for supporting energy efficient lighting solutions in the domestic sector. A smooth transition from old inefficient lighting technology to highly efficient lighting requires further supportive measures and information services for the consumer. Making good energy efficient products visible for the consumer by product testing can prevent this. To this end, comprehensive testing of high efficiency products has been done. More than 370 lamps of 95 different types have been tested during 18 months. Lamps types include LED omnidirectional bulbs and candle-type lamps, as well as LED spots and downlights. All tested lamps, assumed to be “high quality” products, have been selected anonymously from store selves in 12 European countries following agreed quality criteria. All these results will be presented during the talk.|

|“Daylight in the built environment” – My talk at SPARC builds on the talk that I gave last year and offers a more examples and a more finely crafted exploration of the importance of Daylight in the Built Environment. The talk is an exploration the challenges and opportunities to integrate daylight design (and lighting design) in built environments. I will explore places in where daylight plays a significant role in defining the architectural qualities of that space. I will consider the importance of daylight integration, some of the innovations where daylight is being integrated into the architecture or urban design. I will talk about the consequences of poor urban design outcomes that limit access to daylight to buildings and urban spaces. The talk will consider the history of daylight integration to buildings, lighting design and how lighting design and architecture might come together to become a single discipline around light and space. The talk centres on the experiential aspects of light and space and seeks to provide an overview of the importance of daylight integration in urban space. The possibilities of this daylight and electric light integration is explored in projects that Di Mase Architects has begun to explore along with the work of local and international architects.|
