TROX Air Conditioning Perfect for Prestigious Central London Revitalisation Project

TROX Air Conditioning Solution Perfect for Prestigious Central London Revitalisation Project

TROX - 21 Dartmouth Street, London
For the prestigious redevelopment project at 21 Dartmouth Street, London, a premium occupant experience was essential to complement the enviable location. The installation of a TROX air conditioning solution, including TROX X-CUBE air handling units (AHUs), and X-AIRCONTROL modules, with the X-AIRCONTROL Zonemaster, is enabling the building to achieve outstanding levels of efficiency alongside elite levels of comfort.

The 21 Dartmouth Street building is situated in the heart of St. James’s Park, between Buckingham Palace and the Palace of Westminster, a short stroll from Sloane Square’s series of specialist boutiques. The address features a magnificent new rooftop, a majestic lobby and modern business amenities befitting its architectural grandeur. A total of 53,000 sq ft of office space is offered across nine floors, naturally commanding an extremely high degree of occupant comfort.

When specifying the air conditioning system for the building, the main contractor, mac group, and their M & E services consultants, Max Fordham, required a solution which would combine optimum comfort conditions with outstanding environmental performance. The solution, provided by air conditioning specialists TROX UK, incorporates precision-engineered air handling units, and provides the latest VAV capability featuring advanced zone control technology to deliver best-in-class energy efficiency and occupant comfort.

Air handling
At the heart of the system are two TROX X-CUBE air handling units. Each X-CUBE incorporates TROX’s integrated controls package, whereby damper actuators, pressure, temperature and humidity sensors, as well as heat recovery control and fan control strategy, are linked into the X-CUBE digital control network. Both units incorporate thermal wheels with pre-programmed strategies, selected to meet BVU efficiency in accordance of the ErP 2018 standard. This is the highest level of smart technology, combining pre-set algorithms, developed by TROX, to facilitate rapid reactions to changes in building load.

Zone-based VAV control
To deliver outstanding levels of comfort and energy efficiency, the system utilises TROX’s X-AIRCONTROL variable air volume functionality. This is integrated seamlessly with the X-CUBEs and with a TROX X-AIRCONTROL Zonemaster to address the needs of the different occupied spaces across the site. The building is divided into 20 X-AIRCONTROL zones, each of which has a TROX TZ-Silenzio supply controller and a TROX TA-Silenzio extract controller. The X-AIRCONTROL zone modules combine information from humidity, temperature and PIR sensors and ensure the perfect interaction of all air handling components in a room. The system recognises all digital sensors automatically and uses measured values to initiate control procedures.

The X-AIRCONTROL modules also collect information from air quality (VOC) sensors, which can be an invaluable tool in refurb projects, where large amounts of volatile organic compounds can remain present due to new furnishings/fittings and decorative work. Whilst the VOC sensor does not measure CO2 directly, it measures VOC’s exhaled by human beings which are directly proportional to the amount of CO2 exhaled. The VOC sensors detect many potentially harmful compounds (unlike simple CO2 sensors) and can communicate with the system to change the air flow rates, increasing them until acceptably low VOC levels are reached, and reducing again once the compounds have sufficiently dissipated. For a prestige office project such as 21 Dartmouth Street, this monitoring of VOC levels was vital to avoid poor ventilation and its negative impacts on productivity for building occupants.

The 20 zone modules are integrated with the TROX X-AIRCONTROL Zonemaster. This is an intelligent controller which provides a single point connection to the BMS for all of the zones via Modbus TCP or BACnet IP. For larger systems it is possible to connect five Zonemasters together creating a network of up to 125 zones. All configuration of the zones can be achieved easily using the on-board web server located on the Zonemaster. It simply requires a web browser for access, and no specialist skill sets or specialist software are necessary.

Energy efficiency and acoustics
Inherent within the TROX system supplied for 21 Dartmouth Street is a fan optimisation strategy, controlling fan speeds based on damper blade position, which enables energy consumption to be reduced significantly. The Zonemaster monitors the position of all damper blades on the system and adjusts fan speeds in response to changing demands in each zone of the building, ensuring that fans are never operating at a higher level than necessary to meet demand. This provides significant energy savings compared to conventional fan speed control where the fan is commissioned to deliver a maximum system pressure at all times. Another advantage of the reduced system pressures/fan speeds is a reduction in noise, providing acoustic levels that are ideal for office applications.

Practical considerations
To ensure that the building was ideal for IT-intensive office premises, TROX Silenzio air supply and extract units were selected for each zone. These units can obtain an accurate airflow measurement without the requirement for lengths of straight air duct in advance of each module. This reduces the space and ducting requirements, making it much easier to integrate the units in a congested ceiling space.

Ian Thomas, Product Technical Manager - Air Products at TROX UK, commented, “Increasingly, designers of HVAC systems for prestige commercial properties are exploiting the advanced control capabilities incorporated into the air handling equipment itself. This provides an extremely effective alternative to bespoke programming of the BMS, and delivers increased levels of zone-based control for occupants of the building. The 21 Dartmouth Street project is an excellent example of this approach, and we are proud to have played our part in the redevelopment of this prestigious site.”

TROX PWX Fancoils Chosen for Two Chamberlain Square, Birmingham

April 2019

TROX PWX Fancoils Chosen for Two Chamberlain Square, Birmingham

TROX has been selected by BAM Construction to supply PWX fancoils for the second building at Paradise, Birmingham - Two Chamberlain Square. The 183,000 sq ft office building, the vision of Glenn Howells Architects, will join the first building in offering a cumulative 350,000+ sq ft of Grade 1 office space as part of the Paradise masterplan. Inspired by the Victorian architecture of the city’s Grade 1 listed Town Hall and Council House, the building presents a strong facade with elegant, slender columns which run its full height, before stepping back at the sixth floor with a roof terrace. With this aesthetic philosophy in mind and elite technology in hand, the Paradise project, from developer-manager Argent, is set to reinstate Birmingham's civic heart and bring the city into the future whilst celebrating some of the UK's finest Victorian architecture and the legacy of Joseph Chamberlain.

The TROX PWX fancoil range was an ideal choice for the air conditioning system at Two Chamberlain Square, where comfort of building occupants and energy efficiency are key priorities. Launched in 2017, the PWX fancoil was the result of an extensive research and development programme in which TROX rejected incremental product enhancements in favour of a comprehensive rethink of fancoil technology. When developing the PWX range, TROX put the new fancoils through thorough in-house testing, using their in-house test chamber (constructed to comply with ASHRAE 79, BS1397 and EUROVENT 6/3), in addition to extensive corroboration of results at an independent test facility.

As a result, specifiers of PWX fancoils are able to input exact performance criteria for an extremely wide range of thermal and acoustic scenarios when planning their air conditioning schemes, instead of having to rely on less reliable ‘anticipated’ or ‘expected’ data. The TROX PWX range is therefore able to speed up the specification of projects significantly, streamline installation and commissioning, and provide valuable environmental and cost benefits whilst reducing levels of risk.

TROX PWX units feature new inlet attenuators, inlet plenums and discharge attenuators capable of achieving outstanding performance across a wide range of applications. SFPs across the range comply with and exceed Part L requirements, with typical values between 0.15 to 0.25 W/(l/s) at 30 Pa ESP. The availability of in-house testing laboratories at TROX’s factory in Thetford means that fancoil performance can be trialled and tested during the design phase, ahead of installation, to speed-up and streamline projects and to assist best-in-class system design.
