Sustainable Lighting Design

In this episode, we talk with Lisa Heschong, architect and founding principal of the Heschong Mahone Group (HMG), a building science consulting firm, where she led groundbreaking research showing the relationship between daylight and student test scores, retail sales, and office worker performance. Lisa is also the author of the renowned book Thermal Delight in Architecture, and the most recently published book Visual Delight in Architecture, along with many groundbreaking technical publications about daylighting and energy efficiency in buildings. In this episode we will talk with Lisa about some of the topics that she covers in her last book, such as the importance and the value of having a view out, as well as how views can be evaluated. We also discuss the benefits and challenges of considering both daylight and electric light when designing buildings, and conclusions from the various research that she has led throughout her career. This podcast is part of a research-in-practice project on sustainable lighting design by Maha Shalaby & Isabel Villar.

In this episode, we talk with Dr. Till Roenneberg, President of the World Federation of Societies for Chronobiology, and former President of the European Society for Rhythms Research. He has initiated and directed several large national and international research networks and received several international research prizes and has been named “Ambassador of Sleep” by the German Sleep Foundation. Till has published more than 200 papers that have been cited more than 21,000 times and has written two books, “Internal Time” and “The Right to Sleep”. We discuss with Till our biological needs for light and darkness, the causes and consequences of Social Jetlag, Daylight Saving Time, and what key features a building should have to support our circadian rhythm.

In this episode, we talk with Naomi Miller, lighting designer, and Senior Lighting Research Scientist at the United States Department of Energy - Pacific Northwest National Laboratory. Naomi's work focuses on bridging the gap between technology and application. She works with clients and stakeholders to overcome the hurdles facing the adoption of energy-efficient lighting products, raising awareness of the importance of lighting quality and the impacts of light on humans. We discuss with Naomi how lighting standards and certifications can be drivers for good lighting design, the importance of interdisciplinary collaborations between academia, practice, and the lighting industry, as well as her latest research on flicker and circadian lighting. Naomi recently served as a member of the Illuminating Engineering Society's Board of Directors and is both a Fellow of the IES and the International Association of Lighting Designers (IALD). This podcast is part of a research-in-practice project on sustainable lighting design by Maha Shalaby & Isabel Villar.

In this episode, we talk with Sebastian Knoche, leader of Trilux lighting research team and an active member of the European Repro-Light research project. Repro-light is a European research project that aims to support the European lighting industry in moving towards a more sustainable and competitive future. We discuss with Sebastian the outcomes of Repro-light, the lessons learned, as well as the myths and truths that every person working with lighting should take into consideration when having sustainability in focus.

Pete Strasser is the Technical Director of the International Dark Sky Association, IDA. IDA is a non-profit organization, whose mission is to “preserve and protect the nighttime environment and our heritage of dark skies through environmentally responsible outdoor lighting. In this episode we talk with Pete about how artificial lighting at night is impacting our environment, what we can do as lighting designers and users to revert this, and what available technical solutions and tools are at hand to help us protecting the dark sky. This podcast is part of a research-in-practice project on sustainable lighting design by Maha Shalaby & Isabel Villar.

Gayathri Unnikrishnan is a lighting Designer and Vice President of the WELL standard development and Concept Lead for light at IWBI. In this Podcast we will be getting some insights into the Light feature in the WELL certification system and discuss some of the challenges that come up when working with it in practice. As well as how we can better integrate daylight and electric light in the lighting design process. This podcast is part of a research-in-practice project on sustainable lighting design by Maha Shalaby & Isabel Villar.

Marie- Claude is an associate professor at the Department of Architecture and the Built Environment at Lund university in Sweden and an expert on sustainable design at White Arkitekter.  She recently published the book ‘Daylighting and lighting under a Nordic Sky' a student's literature book that touches on qualitative and quantitative aspects of light. In this interview, we will start by discussing some of the sections in the book that are connected to light quality and then further dive into energy efficient strategies for optimizing light in buildings.
