Aiming for net zero: A guide to energy efficient buildings

In the previous issue I wrote about the impact buildings have on greenhouse gas emissions and the potential impact of climate change on the design of buildings. We are all going to be hearing the phrase ‘net zero’ a lot more over the next few years as the UK attempts to balance its...

Climate change: What’s next for UK livestock welfare?

The language of late 2021 has a focus on climate change, and how our leaders are going to commit to consumption and investment policies that will make a significant change for the better. The language is not new but is finding a wider usage; re-think, reduce, re-use, recycle. At the same time the global livestock industry is...

Selecting the Correct Steel Grade

Steel is a remarkably versatile construction material and has so many uses within modern agricultural and industrial buildings.  In addition to the structural frames, which are usually made from hot-rolled carbon steel, galvanized cold-formed steel is often used for the purlins, cladding rails and the roof and wall cladding, while steel bolts hold the structural elements together and reinforcing...

Light: Adding Value to a Steel Frame

Design guidance on lighting for livestock buildings has remained rudimentary for years. BS5502: part 40, (1990) states that natural lighting should be provided for cattle where possible, with supplementary artificial lighting where appropriate. Target light levels recommend 50 lux as standard service illumination and 300 lux for inspection. Similar guidance is given for...

Installation of Photovoltaic (PV) Arrays on Agricultural Buildings

Photovoltaic (PV) panels are becoming an increasingly common sight on buildings across the UK, as owners attempt to turn sunlight into cash while doing ‘their bit’ for the environment. Farm buildings are no exception, especially where electricity is required to power plant and processes within the building. If, however, the PVs are not installed correctly,...
