Birmingham’s St Mary’s Hospice provides vital care and support to people and their loved ones who are living with life­ limiting illness


Every day the hospice cares for 400 people living across Birmingham and Sandwell and can offer personalised support in people’s homes, in their community and at the hospice itself. Its aim is to help people live well with their illness, right up to the end of life and be there for their families, carers and loved ones.


During the summer of 2018 the decision was taken to replace the existing inefficient heating plant with 2No Ethos FS 350 floor standing condensing boilers from Mikrofill. Installed by long established mechanical contractor, Guardian Gas, each stainless steel boiler employs 2No independent burners, each with a 10 > 1 modulation providing an overall turn down ratio of 40 > 1 (700kW > 17.5kW). This ensures the buildings load is consistently matched by the boilers whilst maximising fuel efficiency.


A Mikrovent 750 low loss header c/w air and dirt separation complimented the installation by trapping dirt particles five microns and larger via its integral stainless steel brush.

Priva BMS helps preserve historic HQ of National Centre for Writing


The National Centre for Writing in Norwich has installed state­of­ the­art Priva Blue ID technology to monitor and control the internal climate


The upgrade is part of a £2 million extension and refurbishment project, part funded by the Arts Council England.


The organisation is housed in Dragon Hall, a Grade I listed, 15th century medieval trading hall of significant historic interest. The building is renowned for its spectacular timber crown-post roof and intricately carved dragon.


The existing BMS, as well as being unreliable, suffered from both poor usability and operability, being described as “fiddly and not user friendly”. To address the situation, Norwich-based Electrical and Mechanical Controls Ltd (EMC) was appointed to the project. “Energy saving wasn’t the primary driver for this project,” says Dan Millard, Technical Operations Manager at EMC. “Conservation of the Grade I listed building was the main concern. Dragon Hall incorporates a lot of old timber and it is therefore vital to ensure the climatic conditions are right, for example – keeping an eye on the humidity to ensure the beams don’t degrade.” “Priva is our BMS manufacturer of choice due to the products being


reliable and cost effective,” says Millard. “We deployed Priva controllers for the main panel at Dragon Hall, utilising Priva Blue ID C4 controllers that


interfaced the Mitsubishi air conditioning system via BACnet. We also used the Priva cloud connection [TC Manager Connect] to integrate the new wing with the rest of the building.” “From a planning point of view, care was needed with regard to what we mounted on the walls,” says Millard. “With this in mind, the sensors used had to be visually in keeping with the rest of the building.”


The upgraded and extended Dragon Hall was opened in June 2018.


www.priva.com/uk International Convention Centre Wales to be air conditioned by Carrier


Carrier's award­ winning high efficiency AquaForce Vision 30KAV chiller has been chosen to provide high quality air conditioning for the new International Convention Centre Wales (ICC Wales)


Located at the prestigious Celtic Manor Resort, host of the Ryder Cup and recent NATO Summit, the ICC Wales project is an £83.7m joint venture between the resort’s owners and the Welsh Government. The new venue, which opens in 2019, will accommodate 5,000 delegates and includes a 4,000sqm pillar-free main hall and a 1,500 seated auditorium.


Two Carrier 30KAV chillers equipped with Greenspeed Intelligence inverter-driven screw compressors have been selected to air condition the new facility, each delivering 791kW of cooling. The innovative technology recently won the Air Conditioning Product of the Year 2018 in the UK's Cooling Industry Awards, due to its energy efficiency and excellent environmental credentials. The chillers are being deployed in a duty share configuration, with each chiller sized for 58 per cent of the diversified load to provide outstanding resilience and continuity of cooling at all times. Due to the coastal location, the units have been


specified with Super Enviroshield condenser coating which is factory-applied and provides an extra high level of corrosion protection for the high efficiency all-aluminum heat exchangers from corrosion.


Peter Davies, director of contractor and installer CMB Engineering, says: “Carrier has a reputation for reliable, well-engineered systems, and the company's senior sales engineer Russ Tyrell provided helpful support throughout the project. The efficiency performance of the new 30KAV chiller range is excellent due to the use of inverters that precisely match cooling output to current load. This is highly attractive for end users, as it delivers high quality comfort conditions for occupants, while minimising running costs and enhancing environmental credentials, all important considerations in the ICC Wales project.”

The Sir Jack Hayward Ground is the first team training and academy base of Premier League football club Wolverhampton Wanderers


The state of the art facility was opened in 2005 and named in honour of the club’s Life President and former owner Sir Jack Hayward. It features two high-quality under-soil heated pitches, an indoor pitch, a fully equipped gymnasium and a hydrotherapy pool. In addition, the training ground's medical and physiotherapy facilities made it the first British sports club to establish a fully accredited onsite professional sports laboratory. Established West Midlands contractor Lord Combustion Services, proposed the replacement of the existing PU equipment with a pre-

commissioned Mikrofill pressurisation package. This included two x 700 litre expansion vessels, two x service drain valves and a Mikrofill 3 PU unit.


The pre-commissioning includes the setting of the nitrogen/air charge in each of the vessels to match the cold fill parameter on the Mikrofill unit.


In turn, this ensures the vessels absorb the correct amount of volumetric expansion when the system operates at its designed final working pressure.
