Influence of microclimate control scenarios on energy consumption in the Gallery of the 19th-century Polish Art in the Sukiennice (the former Cloth Hall) of The National Museum in Krakow

摘要

The main aim of preventive conservation, ensuring protection of historic collections, is stabilization of relative humidity, and for some materials also temperature, in the interiors of historic buildings or museums. The improper microclimatic parameters may cause irreversible damages. On the other hand, strict control of indoor climate is expensive. Definition of optimal microclimate control in terms of energy use, taking into account most important, sometimes even contradictory factors, requires interdisciplinary cooperation, among others in the field of conservation, collections' care, architecture, building physics and HVAC systems. Due to the type of historic objects and specific microclimate requirements, hygrothermal simulations of whole historical buildings are essential for the most part of a case study. The paper presents an analysis of energy consumption according to various microclimate control scenarios for The National Museum in Krakow: The Gallery of 19th-century Polish Art - located in Renaissance Cloth Hall in Krakow (UNESCO World Heritage Site). The analysis is based on the results of simulations performed with WUFI~RPLUS software and in situ measurements. The microclimate control variants were developed, among others, on the basis of ASHRAE and ICOM-IIC guidelines. The research was supported by The Polish National Centre for Research and Development within "HERIVERDE" project.
