Pipes, valves & fittings Another example of a small change making a big


difference is the example of a building hot water system, simply changing a 4-port constant volume valve for a PICV can have a significant impact even on an older system. Switching to 2-port PICVs means that the hot water is delivered to a specific location, only where it’s needed and with no wasted energy.


The introduction of PICVs into an existing HVAC


system helps to stabilise temperature range in a building, while also allowing the system to react to heating and cooling demands in different occupied spaces – without overshooting set- point temperatures. Greater control and better accuracy of indoor temperatures are better for the environment as well as occupants. Naturally, when working on a refurbishment


project it’s possible to find systems that aren’t in great shape. In older or dirty systems, prevention is better than cure and there’s no replacement for a robust maintenance regime. However, engineers can check that a system includes strainers, filter pots and non-return valves all of which can prove very useful in keeping things running smoothly. The careful consideration of backflow products in a system can help to reduce contamination in open-loop systems. Optimising cleanliness can support overall system efficiency and reduce future breakdowns. A further product with consideration for those


less-than-ideal retrofits in older buildings is solenoid valves. They’re an invaluable preventative measure that can be easily retrofitted to prevent dripping taps, non-closures and leaks, and provide energy savings particularly in buildings where occupancy diversity varies considerably. Pressure reducing valves (PRVs) are also a useful


choice for new-build and refurbishment projects. They are designed to control the pressure of incoming water from the mains supply. This external pressure can be unpredictable, so the PRV prevents surges of high-pressure water that could damage crucial system elements such as boilers, as well as causing leaks in pipework. As water is an increasingly precious resource,


PRVs can also play an important part in reducing its wastage by reducing the outlet pressure of taps, achieving significant water savings over time. PRVs, non-return valves and solenoid valves


are good examples of how inexpensive updates can make systems easier for building owners to manage their HVAC systems by helping to prevent breakdowns and call-outs. While not directly related to net-zero, any technology that extends the lifetime of systems subsequently reduces the operational carbon footprint of a building by reducing the need to replace equipment. Building services can make a significant


contribution in driving Net Zero in our built environment. It’s becoming more challenging to find


potential savings as targets are set ever-higher. However, at Albion we believe that with attention to the details of a hydronic system, particularly in valve selection, there are energy and costs savings to be found. Valves can provide a cost-effective solution that not only meets building efficiency and carbon targets, but also supports longer operating life for the system. Whether it’s a new-build or retrofit project,


correct valve selection can help designers achieve the system performance they’re looking for.
