图书馆和档案馆收藏了大部分文化遗产。图书馆和档案馆的主要目的是提供适当的室内气候条件，以保存其收藏。通常，存在大量吸湿材料，这有助于稳定的室内气候条件。由于游客的存在，有限的干扰发生在存储库中，并在很大程度上排除了热舒适的要求。库档案显示更宽容的设定点控制与允许的波动的潜力。目前很少有研究动态设定点控制和间歇调节在图书馆和档案馆。本研究的目的是探讨间歇调节和动态设定值控制的可能性，在荷兰的图书馆案例研究的能源影响和小气候行为。通过2016年8月至2017年8月的温湿度监测活动，在常规条件和干预期间（夏季和冬季）（空气处理机组关闭）对当前室内气候进行了评估。时间和空间的测量提供了重要的信息的小气候行为的调查库。一个经过验证的多区域模型被用来研究多个设定点的策略。结果表明，间歇调节的潜力取决于是否使用动态设定点条件在运行时间（如ASHRAE气候类）。如果应用静态条件，则能量需求显著增加，然而，在动态设定点控制下，显著的能量节省是可能的。使用寿命乘数用于评估化学品风险。大多数研究的设定点策略显示出增加的化学风险。
Libraries and archives house a majority of cultural heritage objects. The main purpose of libraries and archives is to provide suitable indoor climate conditions for preservation of their collection. In general, a large bulk of hygroscopic material is present which aids stable indoor climate conditions. Limited disturbances due to visitor presence occur in repositories and excludes to a large extent thermal comfort requirements. Library archives show potential of more tolerant setpoint control with permissible fluctuations. Little research is present into dynamic setpoint control and intermittent conditioning in libraries and archives. The aim of this study is to explore the possibility for intermittent conditioning and dynamic setpoint control on the energy impact and microclimate behavior in a library case study in The Netherlands. By means of a hygrothermal monitoring campaign from August 2016 to August 2017 the current indoor climate has been assessed under regular conditions and intervention periods (summer and winter) where the air handling unit was turned off. Both temporal and spatial measurements provided important information on microclimate behavior of the investigated repositories. A validated multi-zone model was used to investigate multiple setpoint strategies. Results show the potential of intermittent conditioning depending on whether dynamic setpoint conditions are used during operational hours (e.g. ASHRAE climate classes). If static conditions are applied, energy demand increases significantly, however, under dynamic setpoint control significant energy savings are possible. The lifetime multiplier is used to assess the chemical risks. The majority of investigated setpoint strategies show increased chemical risk.
