Technical Tuesdays: technical conservation webinars
These free weekly webinars, presented by Historic England's Technical Conservation Team, provide delegates with an in-depth look at a range of technical conservation topics. The Technical Tuesday series will explore the following themes:
Beneath the surface
Survey and inspection
- 12 May - Infrared thermography
- 9 June - Geospatial survey
- 30 June - Materials Science for building conservation
- 14 July - Damp
Buildings at risk
Survey and inspection 3: damp - 14 July
In the final webinar on the theme of survey and inspection we’ll look at the principles that should be adopted when investigating moisture-related issues in traditional buildings, including the factors to take into account when determining the causes of damp in old buildings. We will also explain the potential and limitations of various methods for assessing moisture in building fabric and how measurement and monitoring can help in diagnosis of damp-related problems.
Beneath the surface 3: concealed decoration – 7 July
Until the 20th century, wall paintings were commonly used to decorate buildings of all types and status. In historic buildings, wall paintings may survive exposed, but they are often hidden under layers of paint, plaster, or wallpaper (or all of these). They can also be concealed behind panelling or later walls or features. In this webinar we’ll talk about how to assess the potential survival of historic painted decoration in a home or building, and what to do if wall paintings are discovered.
Materials science for building conservation – 30 June
This webinar will explore the contribution of materials science to the conservation of built heritage. We will explain how scientific techniques carried out in the laboratory or on site can be used to learn more about material composition and causes of decay, and how this can inform repair strategies and specifications. We will describe some of the challenges and limitations to be aware of when commissioning materials science work. We will also present an overview of the setup of pilot-sites to assess conservation treatments in historic buildings, and the role of materials science in the development of innovative conservation treatments.
Building services 2: Installation – 23 June
Building services engineering systems - having considered the principle reasons for building services engineering in the first webinar we now start to look at how to control the internal environment and how this influences the decisions on the design and methods of installation for the building services engineering systems.
Buildings at risk 2: Graffiti - 16 June
In this webinar we’ll talk about methods of removing graffiti from historic buildings, primarily masonry –stone, brick and concrete - as well as approaches to preventing it.
This webinar will be of interest to anyone caring for historic buildings; including local authorities, building owners, practitioners.
Survey and inspection 2: Geospatial survey - 09 June
Geospatial survey encompasses a wide range of survey technologies for capturing three dimensional data and digital imagery of heritage objects, buildings and landscapes. Once processed the outputs provide accurate, scalable base documentation that aids a variety of applications including archaeological/architectural analysis, site presentation, condition survey, structural monitoring and conservation works planning.
This webinar will discuss the heritage application of geospatial survey technologies and through reference to two case studies, consider their use for historic buildings and structures alongside some of the challenges faced when undertaking or commissioning such survey work.
Beneath the surface 2: fibrous plaster - 2 June
Fibrous plaster is a material that is hugely prevalent in historic buildings, but is little recognised, completely ignored in scientific research and poorly described in publications on architectural history and conservation. This webinar will look closely at the material itself, its use and its conservation.
Building services 1: principles and decision making - 26 May
Building services engineering systems are sometimes viewed as causing damage and an intrusion; especially when considering historic buildings. However, they are now a necessity in many situations to meet the expectations of our society. Even before decisions are made on the actual systems to be used there are a number of key questions and considerations.
This webinar is the first of three on building services and looks at some of these sometimes conflicting issues and how they feed into the decisions made for the building services engineering required.
Buildings at risk 1: fire in thatched buildings - 19 May
Since the 1990s, the number of fires in thatch-roofed buildings has risen significantly. Evidence strongly suggests that this is related to the increasing popularity and use of wood-burning and multi-fuel stoves, but the actual mechanism and cause has long been a subject of contention.
This webinar will explain the background to research commissioned by Historic England in collaboration with NFU Mutual Insurance Ltd to investigate the causes of fires in thatched buildings fitted with a wood-burning stove. The results have challenged previous theories and have resulted in new guidance to reduce the risk of fire in thatched properties.
Survey and inspection 1: thermal imaging - 12 May
Infrared thermography is a useful surveying tool to determine the performance characteristics of historic buildings and their services and will help to determine their structural and environmental integrity. Applications can cover assessing energy efficiency improvements, deterioration of fabric from damp, identifying defects to investigating electrical faults and anomalies in building services. The webinar will discuss the use of infrared thermography for historic buildings and building services, covering the theory of thermography, its limitations and issues of interpretation.
Beneath the surface 1: earthen mortar - 5 May
Anyone working in conservation will be aware of the past use of lime mortar, but what about earthen mortar? Where was it used and what was it used for? This presentation explores this under-appreciated material, explaining what it is, where and how it was used, and how to approach repair and conservation.
A common sense approach to damp: part 2 – 18 March
Historic buildings, like modern buildings, can be adversely effected by damp. Damp in buildings can come from a variety of sources be it flood water or broken drains. However, in mitigating the effects of damp in buildings we need to better understand the properties of building materials new and old and how water reacts with them.
This is the second of two webinars in which we will be looking at the sources of damp and how we can best mitigate the effects and/or address the damage caused.
Glazing and the environment – 19 February
Windows are often the first part of a building people think of changing when they worry about comfort, or energy and carbon. But how do you choose the best approach for a historic building, and know that you will be benefiting the building, the environment, and of course the occupants? This webinar puts glazing into a historic context, and will help you approach these difficult questions in a new way. Join Dr Robyn Pender from our Technical Conservation teams and Katie Parsons, Historic Environment Planning Adviser for London and the South-East, as they explore how to deal responsibly with glazing, from sash windows to modern facades.
A common-sense approach to damp – 15 Jan
Historic building, like modern buildings, can be adversely effected by damp. Damp in buildings can come from a variety of sources be it flood water or broken drains. However, in mitigating the effects of damp in buildings we need to better understand the properties of building materials new and old and how water reacts with them. In this webinar we will be looking at the sources of damp and how water behaves when it it comes into contact with various building materials.
Acting in a flood emergency – 11 December 2019
In the midst of a flooding crisis, it can be difficult to know where to turn with confidence for advice on how to look after your historic building before, during and after the waters arrive. This webinar will introduce you to the ways traditional buildings handle floodwater (including the latest results from Historic England's research programme, and how to get the best drying regime in place), and what you can do to increase both the resistance and the resilience of your building.
More webinars are coming
Another series of Technical Tuesday webinars is planned for the autumn.
Historic England is an IHBC-recognised CPD provider, and participation in this event may provide part of the compulsory CPD requirements of a full or associate IHBC member.
