The International Journal of Sustainable Lighting (IJSL) is the successor of the former Ingineria Iluminatului - Journal of Lighting Engineering, issued in Romania starting with 1999. IJSL aims to become an internationally recognized journal and to complement the existing prestigious lighting journals with an emphasis on emerging lighting issues including light pollution, chronobiology, sustainable buildings by extending its readers and authors to the worldwide lighting communities. The IJSL is an open access journal and is published bi-annaully in June, and December each year.

Aims and Scope

The International Journal of Sustainable Lighting is based on a change of paradigm from energy-efficiency to trans-disciplinarity (including energy, ecology, biology, green buildings, astronomy); it is a peer reviewed scientific journal encompassing experimental, theoretical and applied research results with respect to field of sustainable lighting. It provides a forum for architects, engineers, biologists and researchers involved in the design, operation, construction and utilization of lighting.

The foremost objective is to give a quality online publication to our readers and authors. In this pursuit, our effort focuses upon quality publishing and an unquestioned commitment to the highest standards of professional and corporate ethics.
