ABSTRACT This paper describes a pioneering in situ study of the daylight characteristics of a historic house interior. A combination of lux measurements inside and outside a historic showroom and recording of sunshine hours have been used together with a log of the room blind operation to understand the daylight characteristics of the room under different weather conditions, blinds settings and season. Average lux, daily lux hour dose, time below 30 lux and daylight factor metrics have been derived to assess daylight conditions over a 10-month period for both conservation of light-sensitive collections and the viewing experience of visitors. Recommendations are made on how to improve daylight management for conservation and visitor experience.

改进历史陈列室的日光管理：一种基于详细记录和分析的方法

摘要 本文描述了对历史悠久的房屋内部日光特征的开创性原位研究。结合了历史陈列室内外的勒克斯测量值和日照时间记录，以及房间百叶窗操作的日志，以了解房间在不同天气条件、百叶窗设置和季节下的日光特性。已推导出平均勒克斯、每日勒克斯小时剂量、低于 30 勒克斯的时间和日光因子指标，以评估 10 个月期间的日光条件，以保护光敏收藏品和参观者的观看体验。就如何改进日光管理以保护和游客体验提出了建议。
