Functional Fires in Historic Buildings: their impact on environmental conditions and response of timber objects

Abstract
Approach my doctoral research through the discipline of material and object decay through environmental conditions. Historically in Britain, buildings have been heated by open fires, but today they are mostly heated with central heating systems. This has led to a dramatic change in the internal environment within buildings, which impacts not only upon the fabric of the building but also the objects kept within them. In heritage, conservation heating aims to keep objects at certain relative humidity levels, rather than comfort temperature levels, but this is not always the case.The research is aimed at better understanding what the environmental conditions were within historic buildings when they were solely heated by open fires. Experimenting with buildings and open fires, logging humidity and temperature in a three dimensional grid pattern and making use of thermal imaging so as to create a detailed picture of the environmental conditions within buildings. This data will be fed into climate chambers in the laboratory, and historic materials will be monitored to produce an accurate picture of the impact historic heating patterns had upon various materials.

| Description | The response rate of timber to various humidity ranges. This has (surprisingly) never been properly research in a detailed way before and was essential for the production of a reference scale as part of the PhD study. |
| Exploitation Route | The method for the production of data on the response rate and equilibrium of timber samples can be re-used across a broader range of timbers/materials to provide a larger reference scale. |
| Sectors | Agriculture Food and Drink Construction Environment Manufacturing including Industrial Biotechology Culture Heritage Museums and Collections |
| Description | The care of historic objects in the buildings at Amgueddfa Cymru - National Museum Wales St Fagans. |
| First Year Of Impact | 2016 |
| Sector | Culture, Heritage, Museums and Collections |
| Title | Data of the reaction of historic wooden samples and their response to various humidity patterns. |
| Description | This data shows how samples of timber with original coatings from historic timber respond to environmental change. New research has shown a possible link between repeated daily fluctuations, and the hastening of overall moisture loss to a sample. |
| Type Of Material | Database/Collection of data |
| Year Produced | 2020 |
| Provided To Others? | No |
| Impact | This will impact the way historic furniture and cellulose based objects are stored and displayed in museum collections. |
| Title | Efficiency calculations for open fires encompassing converted heat |
| Description | Previous experimentation into open fires neglects to calculate chimney heat gain and convected heat. This new method of analysis utilises thermal imagery to make a more holistic approach to the efficiency of open fires. |
| Type Of Material | Data analysis technique |
| Year Produced | 2020 |
| Provided To Others? | No |
| Impact | This data will be useful for those who wish to have a method for calculating heat gain from fireplaces throughout a building which does not concentrate singularly on radiant heat. |
| Title | Model of humidity patterns in solid wall constructed building when heated by open fire |
| Description | Utilising Matlab a 3d model has been created to visualise the humidity patterns with a room when heated by open fires |
| Type Of Material | Computer model/algorithm |
| Year Produced | 2020 |
| Provided To Others? | No |
| Impact | This is the first time open fire heating has been visualised in this way, especially in regards to humidity. |
| Description | Collaborative Doctoral Award, Joint Partner National Museum of Wales |
| Organisation | National Museum Wales |
| Country | United Kingdom |
| Sector | Public |
| PI Contribution | Research with the National Museum is the basis of the whole thesis. Access to historic buildings and understanding their heating patterns and responses when open fires are utilised in a traditional method. |
| Collaborator Contribution | Access to the historic buildings at St Fagans, use of the buildings and fuel, access to office space, funding for equipment and outreach, provision of historic material samples. |
| Impact | Outcomes will take the form of a PhD, a set of guidelines for the management of fireplaces in historic buildings and a conference to deliver the work. Other papers and publications are also likely. |
