As an Electrical Contractor that provides many services to a number of clients across East Sussex, the rest of the UK and even abroad, we have become very familiar with HVAC systems and BMS. For many building types a HVAC used in conjunction with a BMS can be exceedingly beneficial, it can save both time and money, and allow for buildings to maintain a comfortable and safe environment.
At Blair Installations our Brighton based electricians and project managers have a wide variety of experience of working with HVAC control cabling, and have worked on numerous projects and have utilised Belden, Bus, YY, SY and CY cabling systems.
We are experienced in designing and installing all types of cable containment systems, as proven by the testimonials we have received from previous clients. If you are considering using our services as electrical contractors to give you control of your building, there are some things that you should know, including understanding some terminology, as well as being informed of the benefits to a HVAC system or BMS.
HVAC stands for Heating, Ventilation and Air Conditioning, and is a control system that allows an organisation to control the heating and air conditioning of their building using sensors to ensure that things such as the temperature are kept at a comfortable level.
BMS stands for Building Management System, but is also known as a Building Automation System (BAS), and is a system that controls and monitors mechanical and electrical equipment. A BMS can encompass a HVAC system which would controls ventilation and air conditioning, but also give control to power and lighting, as well as fire and security systems.
For these sorts of control systems there are three different types of cable: YY, SY and CY. SY cable is suited to installations with medium to high mechanical stress due to its Galvanized Steel Wire Braid (GSWB), and whilst YY and CY cable are very similar, they lack the mechanical protection provided by a GSWB. YY is a versatile cable that works well in environments with light mechanical stress and CY cable provides protection against external electromagnetic influences, as it has a tinned copper wire braid with polyester binder tape.
Where a BMS really excels is that it affords you better control over your power consumption. With a properly designed, installed and maintained system, you gain control over how your building is being run, allowing you to cut costs by reducing unnecessary energy consumption. This can be achieved by scheduling some systems to only run when necessary. A well installed HVAC system and BMS will also reduce issues such as heating components and circuits overheating, causing unwanted heating across a building.
It’s Not Just About Heat
A well designed, installed and maintained HVAC system will allow you to monitor not just heat, but other environmental factors that occupants will not always consider, such as room humidity and air movement. This is something that when successfully monitored will make an environment far more comfortable.
Won’t This Be Expensive?
One of the common misconceptions about HVAC systems and BMS is that they will be costly and that only large organisations will be able to afford to have them. It’s important to be aware that as with most electrical projects, a BMS is scalable and is designed to suit your needs, not just for large office blocks or industrial complexes, as such the cost is scalable too. As mentioned above a BMS or HVAC system can help to reduce costs by conserving energy.
Internet of Things
A phrase that is becoming used more commonly nowadays is the Internet of Things, essentially what this is referring to is the connectivity of real physical systems through the internet, and this isn’t limited to accessing a computer or printer that is in a different building. The majority of BMS can be networked to work over the internet, and can even be accessed by a web browser, meaning that you won’t necessarily need a specific work station to operate a BMS from, and you won’t necessarily need to be in the building you’re controlling, essentially streamlining the operation of a BMS. This ease of use doesn’t mean that you won’t need some training to use a BMS, but you don’t need to be an expert to utilise these controls.
