Study offers historic buildings protection from climate change

24.08.2010
Some of the nation's most historic buildings and monuments may be better protected from decay in future, following a development by engineers.

Researchers at the University of Edinburgh have devised a method of forecasting damage caused by the weather to stone buildings – including statues, monuments and other historic sites, as well as modern masonry buildings.

The development allows conservationists to estimate the likely impact of long-term climate change on stonework and brickwork to determine the most suitable plan for preservation.

Studies show that a changing climate could have a significant impact on the deterioration of stone and brick buildings.

Building deterioration is often caused by water from the ground rising up through the stone. As water evaporates, salts are left behind which crystallise at the surface. Damage can also be caused by the physical impact of ice forming and melting during cold weather.

Climate change is expected to lead to higher temperatures and lower humidity, which would increase the rate of water evaporation from stone buildings and subsequent deterioration. Damage that would take hundreds of years under present conditions could be significantly accelerated.

Weathering damage can cause disfigurement to monuments and buildings and lead to crumbling or collapse. Increased rates of damage are likely to impact on maintenance costs.

The study, the first of its kind, created computer models of water movement in stone, based on data from previous studies. The research, carried out as part of a Leverhulme Trust-funded project led by the University of Oxford, was published in Proceedings of the Royal Society A.

Dr Andrea Hamilton of the University's School of Engineering, who co-led the study, said: "This research allows us to predict the effect of climate change on water movement through buildings, enabling engineers to decide on the most appropriate method of preservation in the years ahead."

Professor Chris Hall of the University of Edinburgh's School of Engineering, who also co-led the study, said: "The work shows for the first time the critical importance of evaporation in driving the flow of water through masonry structures."

Im Focus: Electron highway inside crystal

Physicists of the University of Würzburg have made an astonishing discovery in a specific type of topological insulators. The effect is due to the structure of the materials used. The researchers have now published their work in the journal Science.

Topological insulators are currently the hot topic in physics according to the newspaper Neue Zürcher Zeitung. Only a few weeks ago, their importance was...

Im Focus: Significantly more productivity in USP lasers

In recent years, lasers with ultrashort pulses (USP) down to the femtosecond range have become established on an industrial scale. They could advance some applications with the much-lauded “cold ablation” – if that meant they would then achieve more throughput. A new generation of process engineering that will address this issue in particular will be discussed at the “4th UKP Workshop – Ultrafast Laser Technology” in April 2017.

Even back in the 1990s, scientists were comparing materials processing with nanosecond, picosecond and femtosesecond pulses. The result was surprising:...

Mapping the interaction of a single atom with a single photon may inform design of quantum devices

Have you ever wondered how you see the world? Vision is about photons of light, which are packets of energy, interacting with the atoms or molecules in what...

Im Focus: Novel silicon etching technique crafts 3-D gradient refractive index micro-optics

A multi-institutional research collaboration has created a novel approach for fabricating three-dimensional micro-optics through the shape-defined formation of porous silicon (PSi), with broad impacts in integrated optoelectronics, imaging, and photovoltaics.

Working with colleagues at Stanford and The Dow Chemical Company, researchers at the University of Illinois at Urbana-Champaign fabricated 3-D birefringent...

Im Focus: Quantum Particles Form Droplets

In experiments with magnetic atoms conducted at extremely low temperatures, scientists have demonstrated a unique phase of matter: The atoms form a new type of quantum liquid or quantum droplet state. These so called quantum droplets may preserve their form in absence of external confinement because of quantum effects. The joint team of experimental physicists from Innsbruck and theoretical physicists from Hannover report on their findings in the journal Physical Review X.

“Our Quantum droplets are in the gas phase but they still drop like a rock,” explains experimental physicist Francesca Ferlaino when talking about the...
