Our selection of case studies showcase a cross section of recent QODA projects.

We are an energetic and enthusiastic Design Engineering Consultancy led by highly experienced and talented engineers, working across mechanical, electrical and sustainable areas of building design. To find out more about what we do, check out our case studies below.

Case Study

University of the West of England (UWE) SAP3

QODA have been appointed as part of the design team lead by architects Stride Treglown, for the UWE SAP3 project which consists of the development of a new 2000 bedroom student accommodation scheme. We have been appointed primarily as the Passivhaus and sustainability consultants on the project, having previously worked with the university to produce a sustainability design guide helping to address their 2030 zero carbon targets. QODA are also appointed for MEP duties which are being carried out as part of a joint venture between ourselves and another consultant.

One of the key drivers we are working on is the requirement for the project to meet Passivhaus standards, as well as looking forward to how the project can help facilitate the ability for the university to achieve its end goal of being zero carbon by 2030. The project is also being carried out to full BIM level 2 requirements.

Case Study

Learning Centre – Kew Gardens

QODA are providing Passivhaus consultancy and MEP design for the new Learning Centre at the Royal Botanical Gardens, Kew. The project is set to be pioneering and plant-based as well as achieving Passivhaus Premium standard. The project comprises of a range of classrooms, labs, offices, and a seminar space to provide an inspiring learning experience to visitors. QODA are currently developing the design to take full advantage of the low energy aspirations of the project, including demand-based mixed mode ventilation and natural cooling, reversible heat pumps within the main air handling system, rainwater harvesting and PV. QODA are working closely with the Architect, Hazle McCormack Young (HMY), to guide the built form by developing a range of dynamic models in order to achieve BREEAM exemplary daylighting in tandem with exceptional energy and overheating performance.

Case Study

Residential Development, London Borough of Ealing

The London Borough of Ealing have commenced an extensive programme of residential development across the borough. This exciting masterplan includes a number of sites (currently 10) which have been divided into 3 packages for design and construction purposes. QODA have been appointed as MEP designers for Package 3 and have also secured a role across all 3 packages as Net Zero Carbon Champions. We will be employing Passivhaus modelling and assessment to inform the design and deliver Ealing’s commitment to carbon reduction. Ealing are developing their net zero carbon design guide and have identified Certified Passivhaus building as a key part of its strategy.

Case Study

Convent Way

QODA have been appointed as MEP and Sustainable Engineers for the 1000 dwellings masterplan at Convent Way, which spans across 5 phases. The project is trying to set a new urban dwelling standard for the London Borough of Hillingdon in terms of integrating Passivhaus design, landscaping, sustainable transport, and building quality. Car parking will be covered with podiums to create a healthy and vibrant community. QODA are designing a communal ambient heat network to provide maximum benefit to the client with respect to plant capital expenditure and space consumption, while trying to minimise tenant bills. The 2 stage reversible heat pump and passive design features will maximise thermal comfort now, while also meeting the climate challenges of 2050 and 2080 with minimal refurbishment.

Case Study

IDRM, University of Oxford

QODA have been appointed as Passivhaus Consultants for the Institute of Developmental and Regenerative Medicine (IDRM) at the University of Oxford. This is a cutting edge research facility, aiming to promote multidisciplinary working and collaboration across three key areas; cardiology, neurology and immunology.  Working with McLaughlin and Harvey and SRA Architects, QODA are responsible for design and site duties for all aspects of Passivhaus design, including a particular focus on delivering class-leading airtightness. Project value: £23.5m.

Case Study

St Peter’s College, University of Oxford

Under QODA’s leadership, St Peter’s College committed to the Passivhaus Low Energy Building standard as a key approach to delivering their sustainable building aspirations. QODA were appointed as Passivhaus Consultants for the project, guiding the design team to develop a compliant scheme. This has involved influencing the construction system, the façade design, as well as dealing with complexities including the proximity of historic structures, façade noise issues, and stringent planning targets, which were comfortably met by the Passivhaus approach. The approach has also led to the simplification of the M&E design, in particular, the proposed use of electric heating, which eliminates the need for wet heating pipework and boilers. The overheating risk has been carefully considered for the project, leading to a thermal strategy consisting of secure ventilation through screened openings, thermal mass, optimised glazing design (including deep reveals for shading), and the option for future cooling to be added through the air system allowing resilience to climate change.

Case Study

Church of England, Pilot Study

QODA were appointed to undertake a pilot study of four heritage buildings for the Church of England, ranging from C17 to 1960s construction. Using a combination of careful site surveys, existing utility data and building energy models of each site, we identified a range of interventions for each house type, and rated them for CO2-saving potential and viability in a sensitive heritage context, as well as for disruption to building occupants. For each site we calculated likely reduction in carbon footprint, against a ‘do-nothing’ baseline (the amount of CO2 the building would emit if it were simply operated in 2030 as it is today).

Case Study

Kennedy Building, University of Oxford

QODA are the Passivhaus and M&E consultants for the rooftop extension at the University of Oxford. Rather than simply replicating the existing façade, we have developed an alternative design with the architect which greatly reduces heating and cooling demands, as well as achieving excellent internal daylight and comfort. As a result, the building is close to achieving Passivhaus performance. QODA have also inputted into the detailing of the building to deliver an “Airtight Design”, while ensuring that junctions are buildable and thermally robust.

Case Study

Court Place Gardens

QODA have been appointed as the M&E and Passivhaus consultants for a 90-home residential scheme for the University of Oxford. The scheme aims to achieve Net Zero Carbon for the site by adopting the Passivhaus standard, combined with renewable energy systems. In our role as Passivhaus consultant we are advising on massing, form, and construction method for the dwellings, as well as developing a simple and cost-effective approach to renewable energy.

Case Study

SLG Convent

QODA have been appointed as M&E and energy consultants for this refurbishment and extension of the accommodation for the Sisters of the Love of God Convent in Oxford. QODA have worked with MEB design and the design team to develop an energy strategy for the new wing which achieves close to Passivhaus performance. We have been intimately involved in the development of airtight and thermally robust construction details and setting construction standards for the contractor.
