About Brightfield Home

What This Site Covers

Brightfield Home publishes material on the planning and assessment of natural lighting in homes. The topics covered include window placement and orientation, the design of light wells in multi-storey housing, and the calculation of daylight factor in enclosed floor plans.

The geographic focus is Poland. The regulatory context, climate data, and construction typologies described on this site are specific to Polish conditions and the standards applicable there. Readers outside Poland should verify that the methods and requirements described apply in their jurisdiction.

All content refers to publicly available documents, standards, and data. No proprietary tools, private research, or commercial partnerships are involved in the preparation of content.

Editorial Approach

Articles are written in an informational style. The site does not promote specific products, manufacturers, or contractors. References cited are to publicly accessible documents including Polish building regulations (Warunki Techniczne), European standards (EN 17037), and open data sources.

Where precise data is unavailable, the site uses neutral formulations rather than invented figures. When regulations or standards change, content is reviewed and updated accordingly.

Content Accuracy

The information published here is intended as general background on daylighting principles and Polish regulatory context. It is not a substitute for professional architectural or engineering assessment. Specific design decisions — particularly those involving compliance with building regulations — require consultation with a licensed professional familiar with the applicable local conditions.
