| Buildings Roundhouse completes a Designing the internal Triple environment for livestock buildings The award winning Roundhouse has reached another milestone by having one customer buy 3 Roundhouses for one farm. Dr Martin Heywood, RIDBA Technical Consultant. airy Farmer, Chris McDonald from Heddon on the Wall in Northumberland bought his first RH30 in 2011 to house his dairy calves, convinced the ventilation benefits would solve the pneumonia problems he was incurring. This unit, the first of its kind for calves at the time, was so successful that in 2013 Chris ordered a second RH30 for his dry cows. In this second building Chris built a five stall parlour to take colostrum from the freshly calved cows to feed the calves. The cows then re-join the main herd only once Chris is happy they are over D the calving and their feed intake meets set parameters. Having bought two RH30’s we thought Chris was done, but in spring 2017 Chris asked if we could fit a RH45 on the farm for his followers. Specifications were agreed and planning submitted and in November 2017 work commenced on site. The Roundhouse is now complete and in use and now we wait to see if he’ll go for a forth! Chris is unique in having three Roundhouses, but we do have a farmer with a current order for three Roundhouses for this year and we have another existing RH30 owner, with his site being prepared ready for a RH45. 28 | Farming Monthly | June 2018 t is essential that animal housing provides a comfortable, clean and dry environment free from hazards and health risks. The design of the building and specification of the materials used to construct it play a major role in achieving these aims and, if done properly, can lead to healthier, happier and more productive animals. This article considers some of the issues that should be addressed by building designers and farmers in order to improve the well-being of their livestock. Ventilation The provision of adequate ventilation is arguably the most important consideration when designing a new building for animal housing. A distinction needs to be made between a well ventilated building and a draughty I one. Nobody, human or animal, wants to live in a draughty building that lets in cold air whenever the wind blows, causing discomfort and potentially ill health. On the other hand, a regular supply of fresh air is essential to replenish oxygen, remove exhaled carbon dioxide and control temperature and humidity. Correct ventilation will reduce relative humidity and the risk of respiratory infections, eliminate stagnant air and avoid unwanted draughts. Factors to consider when designing a building for ventilation include: • The dimensions of the building and layout of any internal partitions • The proposed occupancy of the building • Factors affecting the local wind speed including building location, altitude, shelter and proximity of other buildings. www.farmingmonthly.co.uk
