Light is far more than just illumination – it shapes atmosphere, creates functions, forms spaces, and has a lasting impact on users' well-being. For architectural firms, precise and early lighting design is an indispensable component. Together, we develop holistic, aesthetic, and technical lighting concepts that seamlessly integrate into your architectural vision – sensuous, innovative, and sustainable.
At DAY & LIGHT, lighting design does not begin with the detailed design phase, but rather at the very point where architecture takes shape: in the competition stage, in the urban planning concept, and through an in-depth dialogue with the space, materials and users. Our approach is based on the HOAI service phases and incorporates advanced lighting analyses, simulations and practical model testing.
At the start of every project, we establish contact and clarify responsibilities. We introduce the project team and, together with the clients, define the methodology, processing procedures, deadlines, and budget specifications. We develop an understanding of the construction task, the client, and the end-user.
Even in competitions, many parameters of the lighting effect can be influenced early on through daylight analyses, insolation and shading studies. Together with the planning team, we analyse building geometries, sightlines and orientations with a view to daylight potential, shading and reflection. For this purpose, we record sightlines, thoroughly check daylight penetration, insolation and shading conditions, and take into account not only the architecture but also energy-related and usage-related requirements.
Our range of services for this phase includes:
In the design phase, we deepen the planning by further developing the impact concept and examining technical feasibility. Together with the planning team, we develop detailed lighting concepts that optimally combine visual atmosphere and technical feasibility. We simulate luminance levels and investigate the reflective and transmissive behaviour of glass, materials and surfaces. In this process, we determine the necessary lighting tools such as luminous intensity, light distribution and colour temperatures. These requirements are elaborated in detail and integrated into the lighting concept, which also considers urban planning contexts and spatial relationships. A catalogue of measures with prioritisation and a timeline completes the concept.
Our services in this phase:
In the detailed design and execution planning, precision is key. We develop installation situations, define lighting parameters for tenders, and coordinate interfaces with electrical planning, façade, and interior finishing.
Services in this phase:
We oversee the construction work on-site, check the implementation with a focus on quality, and ensure compliance with all lighting technology specifications. With effective sampling, testing, and adjustments, we optimise the lighting effect in the final stages. After commissioning, we support monitoring, recalibrations, and post-occupancy evaluation.
Our role:
We view lighting design as a collaborative process, closely integrated into BIM-supported model-based planning. This integration ensures the compatibility of our lighting concepts with the overall digital model – including geometries, light sources, and control systems. Changes are automatically communicated to all project stakeholders, thereby minimising planning risks and saving resources.
With over 20 years of experience, we are your reliable partner in museum, public, and private construction projects. We think with lighting expertise and profound design awareness, collaborating with architects in a spirit of partnership, innovation, and precision.
The LiTG publication „Scope of Work for Lighting Design – Part 1: Daylight and Artificial Lighting“ provides detailed specifications for lighting designers and highlights which services are required in addition to those covered by HOAI.
