Essex Carbon Reduction Feasibility Studies
Air Source Heat Pump Systems
Heating and Domestic Hot Water
Essex county identified a number of infant and junior schools as part of their estate carbon reduction programme which had end of service life gas or oil fired boilers providing heating and hot water generation. Detailed site surveys identified building fabric issues including blown double glazing units, poor insulation and poor maintenance access. Opportunities for installation of carbon reduction technologies were assessed using heating design loads and energy estimates including a degree day regression analysis to estimate seasonal and annual energy useage. Capital, energy costs and likely risks were identified. Globe Engineering worked collaboratively with the school heads to minimize student disruption.

Design calculations determined optimum size for boilers, hot water cylinders, hot and cold water storage tanks to suit current demands and regulations. Globe Engineering worked collaboratively with the facility managers to minimize disruption and incorporated prefabricated packages in our designs to minimize site installation works.
Prince of Wales Theatre
Infrastructure Development & Asset Management
Prince of Wales Theatre audiences complained of cold draughts and hot spots, and of poor air quality, causing sleepiness, with huge differences in comfort between the stalls and circle. Globe Engineering identified several problems. HVAC concept designs and detailed drawings were developed to obtain listed building planning consent. The undersized cooling coils were replaced to improve chiller performance and extract fans adjusted to enhance existing plant capacity. Cool-duct panels were added to the brickwork air-ducts to reduce air leakage. A new stage extract system improved the large-scale air distribution, with bespoke eye lash deflectors addressing local air distribution. As a result, overall “Book of Mormon” complaint levels have dropped.
Queens Theatre
Infrastructure Development & Asset Management
Queen’s Theatre’s curved-wall project to widen the stage required the construction of a new substation in the theatre’s underground vaults and new electrical infrastructure. To support the project on the mechanical front and meet the modern requirements in the 100-year-old theatre, Globe Engineering undertook a detailed HVAC asset management survey, identifying HVAC plant replacement needs and designing a resulting program of works. New boiler plant, new air handling units with heat recovery and an upgraded BMS were incorporated, along with new hot and cold water supply and infrastructure for the building. Involving extensive liaison with all stakeholders, the project success will be measured by air quality and its effective distribution.
CITIBANK Data Centre
Problem Solving & Plant Optimisation
Citibank’s data processing centre needed to enhance its HVAC plant reliance to meet the industry’s “Uptime” tiered certification. The data centre’s chillers were at the end of their life and required replacement. Globe Engineering’s analysis of the IT loads and data hall highlighted that Citibank’s CHP system and cooling plant were working inefficiently together. Globe Engineering designed the N+2 electrics and cooling for the data centre, matched the chilled water required to the air handling loads, optimised the systems in the building and hydraulically modelled the chilled water network. Working with multiple stakeholders, a plant optimisation plan was implemented with predicted results of 385,000 kWh p.a. in energy savings.
Hardwick Square
Office to Residential Conversion
Imperial Developments wanted to convert one floor of Hardwick Square (an existing office building) into 9 off high end flats without penetrating the slab to the level below. This required clever design solutions for installing and maintaining the new drainage systems contained within the new multi/level false floors. Globe Engineering provided detailed drawings and calculations to gain building regulations approval, minimize floor depths, prevent flooding of adjacent flats and maintain proper access for maintenance.
CITIBANK Central Belfast Offices
Office Redevelopment
Citibank needed additional office Space in central Belfast and consequently acquired the lease for 5 stories of a suitably located existing office building. Unfortunately the existing air conditioning and ventilation systems were not capable of catering for the Citibank fitout occupancy and computer heat output. Globe Engineering provided at short notice designs for supplementary air conditioning systems and modifications to the ventilation systems. The project was designed, tendered, installed, commissioned and the client occupied the space within about 3 months from the signing of the lease.
Breitling
Design & Project Management
Breitling needed to expand its Tunbridge Wells service centre. A quiet, clean, vibration-free environment was needed to maintain watches, while the cleaning area generated noise, vibration and dust. Globe Engineering was asked to design and develop air handling systems for both working environments. In the service area, circular removable fabric ducts on a pulley system were connected to the air-conditioning pipework to ensure low air velocity movement. In the cleaning area, a negatively-pressured space was created to contain the metal dust given off, with a high-velocity extraction system connected to a cyclone to take the dust away. Cleanliness was enhanced and noise was minimised, creating a healthier working environment and better watch service outcomes.
Stansted Airport
HBS Project
Stansted Airport has a continuing responsibility to maintain it’s baggage handling and security systems to meet passenger safety, comfort and service requirements. Globe Engineering worked with Manchester Airports Group to design the ventilation systems serving the high speed baggage security scanners and as concept guardian for the scanning monitoring facility. A mock-up was built and multiple temperature measurements were taken to determine the air flow pattern around the high speed scanners and the effect of the mezzanine floor over. The ventilation system was value engineered to provide the required air flow whilst reducing the number of fans and optimising the ductwork to allow maintenance and plant replacement access.
Heathrow Airport - Terminal 1
Design & Project Management
Heathrow Airport Limited Terminal 1 required a dedicated chilled water distribution system funded by the expansion of its international departures lounge (IDL). Globe Engineering worked with the lead designer for the production design works to provide detailed designs. Secondary chilled water pumps were replaced with controlled pumps, a new large 4MW chiller was installed and the distribution pipework renewed. Some of the challenges faced included locating the chillers and the cooling towers and these were overcome using detailed 3-D computer models and the resulting production drawings. The chillers were broken down and re-assembled in a multi-story carpark basement and the cooling towers were installed on an adjacent large steel frame. The complex project was delivered on time and to budget, with the required additional chilled water capacity for the IDL.
CITIBANK RDC Free Cooling
Feasibility & Design
Globe Engineering undertook a feasibility study to investigate the possible application of free cooling technologies to help Citibank with their ongoing programme to further improve the efficiency of the RDC Data Centre. This feasibility study analysed the existing system performance, the existing load profile and integration with the CHP plant supplying the building. Free cooling technologies including dry air coolers, adiabatic coolers and closed circuit cooling towers were analysed to determine the optimum system in terms of overall performance, buildability, operational considerations and operating hours. Citibank were satisfied that the free cooling system would provide their desired outcome and Globe Engineering subsequently designed the recommended free cooling system for installation in the near future.
