Daylight & Sunlight

Rigorous analysis that unlocks solutions

Planning policy mandates that new developments ensure sufficient daylight and sunlight to promote healthy living. As urban areas across Ireland become more densely populated, this consideration is essential for creating responsible, future-proof developments that enhance value.

With industry-leading expertise in daylight, sunlight overshadowing, light pollution, solar glare, and photovoltaic analysis, supported by advanced climate-based modelling software, we assess potential impacts on both developments and neighbouring properties. Our clear, actionable advice empowers design teams to navigate these challenges effectively.
