Furse Platt Senior School
Working closely with the project architects, Atkins, Banyards developed an elevation design that maximised daylight into the space. With 100% of the teaching spaces averaging above 300 lux from daylight alone, meaning that the already energy efficient LED lighting can be used sparingly throughout the year.
To prevent this sunlight from overheating the spaces, Banyards utilised the exposed concrete mass in the ceilings and the feature Atria in the centre of the building to create a passive cooling strategy. Using Hybrid Ventilation Units, air is blown across the concrete ceiling slab to keep it cool. In summer, hot air is transferred from the classrooms into the triple height atria where it rises to vent from high level louvres to create a stack effect.
All occupied spaces in the building pass CIBSE overheating criteria TM52 through these ventilation methods, saving the requirement for costly and environmentally damaging air conditioning.
The design was completed with high efficiency gas boilers feeding underfloor heating, which runs at a lower temperature than many other wet heating systems to reduce energy. To meet a council requirement to generate 10% of a new build’s energy on site, 60m2 of photovoltaic panels were installed on the roof, which should produce enough electricity (9 MWh) to meet the annual ventilation load for the building.
The building as designed will perform approximately 25% better than building regulations requirements for energy performance and will provide a world class learning environment for the children attending the school.
We were appointed to complete the MEP design for a new teaching block on the site of a recent 9 block PFI scheme in Ealing, West London. The new block was to be completed using a modular off-site construction method, with Ealing Council as the client.
The school had to comply with the criteria of the London plan. This meant that the building has to achieve an emissions target 35% lower than the national targets set in Part L of the building legislation, complying with the London Plan part 9 cooling hierarchy. We used dynamic simulation modelling to show that the building passed CIBSE overheating criteria TM52.
As a result of the simulation, we showed that the lightweight structure lacked thermal mass to assist with offsetting peak daily room temperatures and developed a solution which could provide natural cooling within the building by taking advantage of increased mass and night time cooling.
A traditionally constructed building has a concrete slab that absorbs heat during hot weather. However, we worked with the SIP construction company to come up with a new solution for their panels that integrated a high-density plasterboard into their wall construction, adding additional thermal mass.
With this new fabric solution, we were able to show the building complied with TM52, using a hybrid natural and mechanical ventilation solution to cool the teaching spaces. This included the south facing science labs that experienced significant heat gain from experiments using Bunsen burners (for example). This immediately greatly reduced the energy demand of the building by removing the need for cooling using air conditioning and improved the thermal comfort for the occupants.
The modular construction company has now added the high-density plasterboard recommended by us to their standard constructions used on projects nationwide.
The new teaching block features a large double height glazed facade over a café area that needed to be designed to limit solar gain. We simulated the annual sunlight that the café was exposed to and designed a feature brise soliel solution that limited the direct radiant gain energy into the space.
As part of our due diligence and commitment to sustainability, we designed the heating system with a simple looped connection point for connection to a future district heating network.
With the school being made up of multiple blocks and surrounded by many commercial properties within a densely populated residential area, the project represented an ideal addition to a potential network to help diversify the load profile in the area. Ealing Council are committed to establishing heat works across the borough in the future.
With the school block being part of an existing campus, the design had to integrate with existing BMS, access control, fire alarm and CCTV systems and the construction had to be mindful of the fact that the block was being built on an active school site.
Following the London plan’s hierarchy: Be-Lean, Be-Clean, Be-Green - we approached the energy strategy balancing the additional up-front investment of high-efficiency equipment against the lower running costs. Once a balance had been achieved between these two factors, we looked to achieve the remaining portion of the 35% reduction using renewables.
A number of energy sources were reviewed, such as biomass and CHP, however, with a large south facing roof the use of PV was an obvious choice for the renewable energy source and aligned with Ealing Councils Energy Strategy, including off site monitoring.
We specified a 155m2 photovoltaic array to ensure the building passed the London plan and provided the school with a source of income as most of the electricity generated during the hot summer months would be exported to the grid as the school will be largely unoccupied for holidays. The school has successfully achieved BREEAM very good and will provide a first class learning environment for the students.
Cox Green School, Maidenhead
This school is located in a densely populated residential area close to the centre of Maidenhead on an extremely constrained site shared by a leisure & community centre, football club, church and council offices. On this project, Banyards had to engage with key representatives from the school, local authority and numerous representatives from the neighbouring properties.
Works were delivered strategically in several phases in order to minimise any disruption to the other stakeholders; specifically the downtime associated with loss of electricity at defined times, which was carefully programmed and communicated.
This phase was primarily an enabling works package undertaken in a six-week summer shutdown period to facilitate the demolition and construction of a new dining block, teaching accommodation and refurbishment of science laboratories.
Banyards worked with the school to identify the services affected by the works to enable the school to continue offering external holiday-club and community services.
Lancaster Royal Grammar School
The scope included mechanical and electrical design services to refurbish a boiler and heating system; delivered in multiple phases in an occupied boarding school on an extremely constrained campus located close to Lancaster city centre.
With a limited six-week school holiday period, works commenced during termtime, while the school was occupied, and hence required detailed planning and a considered approach to phasing.
Banyards produced a programme-of-works through dialogue with the Estates Manager and Head Teacher during the tendering process. The programme became the key document for all parties to manage the construction activities and the school timetable. The age of the existing 160-years old building meant that the route of the services was critical to not spoil the aesthetics but also to ensure the installation was safe and efficient. Banyards worked closely with the various stakeholders to agree these routes through detailed surveys and site-walks accompanied by the client.
St Crispin’s School
This project included the refurbishment of sixth-form accommodation working on an existing live and constrained site in an urban area located on the main A329.
The programme-of-works accommodated the multi-phase aspect of the project and incorporated stakeholders’ needs such that the utility works and upgrades were undertaken out-of-hours to mitigate any loss of teaching time.
Banyards developed a thermal model of the existing accommodation and simulated numerous scenarios to identify the optimum environmental solution that could be afforded within the budget.
The existing building suffered from overheating and Banyards provided three options supported with graphs and reports during the modelling phase to upgrade the fenestration strategy and expose the concrete soffit, in order to transform the enviroment of the building during the warmer summertime months.
The City Business School was founded in 1966, its MSc in Administrative Sciences began in 1967 with the transition to MBA in 1979.
In 2002 the school moved to new premises in the London Borough of Islington and changed its name as part of a strategy formed by Lord Currie of Marylebone, to compete as an international business school in a market dominated by US universities.
The school had previously been spread out across the City of London's Barbican Centre development. Half of the £40 million funding for the new building came from the reserves of City University of London. The school also received a gift from the Sir John Cass's Foundation, founded in 1748 to educate children in the City of London. The school changed its name to reflect the support of the Foundation.
Project AMP provides for the relocation of the Department of Aeronautics into both the City & Guilds Building (previously the Mechanical Engineering Building) and the Skempton Building. This project is being run in parallel with the refurbishment and reconfiguration of the middle third of the City & Guilds Building and reconfiguration of the 3 level annexe building for the Aeronautics relocation.
There is a pressing need to renew numerous elements, services, plant and infrastructure to meet the requirements for world leading engineering research and teaching.
The overall project began in 2011 and is scheduled for completion in 2017.
Langley Park Primary School (second phase)
Banyards appointed as Baxall Construction’s consulting engineer for the second phase of development at Langley Park Primary School in Maidstone.
This second stage development consists of a new extension, increasing the school’s capacity from 1FE to 2FE to help with the significant growth of new dwellings adjacent to Langley Park.
We are delighted to once again be involved at Langley Park; as Geoffrey Osborne’s consulting engineers we were part of the team for the original new build of the school which opened in 2016.
Manchester has always been in the front line in Chemistry. John Dalton founded modern Chemistry in Manchester in 1803 with his theory of atoms; James Joule laid the foundations for the science of thermodynamics in the 1840's and the first UK Professor of Organic Chemistry, Carl Schorlemmer, was appointed to Manchester University in 1874. In modern times Chemistry Nobel Prize winners such as John Polanyi (1986), and Michael Smith (1993) studied for their BSc and PhD at Manchester University.
The last major overhaul of Manchester University’s Chemistry building was in the mid 1990’s, now our Commissioning Validation teams are currently surveying all 10 floors of the Chemistry building, validating the mechanical, electrical and public health services and producing CAD drawings of the mechanical and electrical systems.
Due for completion in May 2016 our MEP validation survey findings will assist the M&E Design Consultants to finalise the Stage 4 Design allowing the construction works to proceed on the refurbishment of the building over the next 7 years.
We are proud to be a part of the the next step of improvements in Manchester University’s ongoing programme of upgrading its Chemistry building to meet the exacting technical requirements of the 21st century.
