Alice McLean, Associate Air Quality Consultant, Ramboll

Abstract
One of the challenges faced by architects and engineers is in designing buildings that create healthy indoor environments whilst at the same time meeting net zero targets.  Indoor air quality is likely to deteriorate as building envelopes become tighter and energy performance demands increase.  However, there is no primary legislation in the UK that requires indoor air quality standards to be achieved and therefore little attention is paid to indoor air quality during the standard design process.  This presentation will introduce the above and recommend an alternative health-based approach to ventilation design for new and existing buildings.

Andrew is a committed indoor air quality professional and an associate of the Institute of Environmental Sciences,

the Indoor Air Quality Association, the UK Indoor Environments Group, the UK Radon Association and the Radon Council along with several APPGs and lobby groups.

Abstract
IAQ improvement is a vital endeavour for British society considering we spend most of our time indoors. There’s a big risk the drive to Net Zero will create unintended consequences for IAQ, health and wellbeing because the predominant ventilation strategy of our 28 million existing domestic properties is not scalable. It’s why so many properties suffer condensation and mould in winter. Active PIV is a term used to describe a unique methodology for affordable and easy to install ventilation solutions that not only improve IAQ but facilitate improved energy efficiency without the enormous energy wastage associated with natural ventilation.

Emma Gibbons, PhD Candidate, UCL

Biography
Emma Gibbons, BSc Hons, CEnv, MIAQM, MIEnvSc, PIEMA, is a PhD Student at University College London. Her field of research is indoor air quality, with a focus on building ventilation and the ingress of ambient air pollution into buildings. Prior to her PhD studies, Emma was a Senior Consultant at Arup, and she has more than 15 years of experience in air quality consultancy. She is a Chartered Environmentalist, a full member of the IES and the IAQM, and a member of the CIBSE air quality working group.

Abstract
A current challenge to indoor air quality is the balance between ingress of ambient air pollution and dilution of indoor pollutants, whilst maintaining occupant comfort. Modern energy-efficient buildings often dilute indoor pollutants and contaminants through well ventilated spaces. However, this can introduce ambient air pollutants into the indoor environment, particularly in urban areas where outdoor concentrations can be at levels greater than recommended guideline values.

In this study, continuous air quality monitoring was carried out in a number of office buildings in central London. Air pollutants and comfort parameters (NO2, O3, CO2, PM2.5, PM10, VOCs, formaldehyde, temperature and relative humidity) were measured using diffusive sampling and continuous monitoring methods. Measurements were carried out in different buildings to understand what influence the ventilation system design and operation had on indoor air pollutant concentrations. 

It is envisaged that case study will be of interest to professionals in all areas of the built environment, including air quality professionals, building services engineers and those interested in healthy and sustainable buildings.

Biography
Michael has worked in air quality for over 35 years, he was a founder member of IAQM and sat on its committee from its formation until 2017. He has assisted with the preparation of several guidance documents from the IAQM, most recently leading the group that produced the guidance on the assessment of odours for planning. He was the air quality lead on many major infrastructure projects including HS2, Gatwick and Stansted Airports, New Tyne Cross and the Replacement Forth Crossing.

After several years leading a large environment consultancy he founded MBAL in 2021 to focus on technical work. At the same time Michael started a masters in History and Philosophy of Science at UCL which he has just completed. As a result, at this conference he is trying out some of his new found knowledge to talk about some ethical and social justice issues associated with air quality standards.

Abstract
This presentation will examine how ethical considerations in public health policy would result in a very different focus in air quality policy compared with our current focus on air quality standards. It will be demonstrated that current policies do not result in maximising public health benefits and can often result in policies that have minimal  benefit. The presentation will examine the UK approach over the last 30 years and suggest how these should change to improve public health outcomes in the future.

Carl Desouza, Research Associate, Imperial College London

Biography
Dr. Carl Desouza is a post-doctoral research associate at Imperial College London. Carl’s research at the Centre for Low Emission Construction focuses on net-zero construction and pathways to achieve carbon neutrality within the industry. His research aims to raise awareness of the impact of dust and emissions on local air quality and health across the construction industry through real-world emission and occupational exposure measurements on active construction sites. He has worked on various research projects which include hydrogen-combustion, machine telematics, retrofit technology, dual-fuel and alternative fuels, personal exposure, power management systems, and construction dust mitigation. Dr. Desouza works with policy makers, regulators, and industry partners to provide independent scientific evidence to understand pathways to achieving the UK governments’ NetZero decarbonisation targets by 2050.

Abstract
The construction sector is one of the largest contributors to GHG and AQ emissions in the UK, with ~300,000 machines consuming ~2.5 mil-tonnes diesel emitting ~6 mil-tonnes CO2e. We have worked with industry partners to provide independent scientific evidence on innovative technologies as alternatives to diesel combustion. Measured emissions from hydrogen combustion demonstrated >95% reduction in AQ pollutants, while H2 fuel-cell trial demonstrated an annual reduction potential of 486 tonnes CO2 and 2.3 tonnes NOx. The outputs from these trials form a route map for the construction industry where uncertainty and regulatory guidance is unclear from the government.

Abstract
We have been working on the feasibility of options to reduce emissions at construction sites working with ‘exemplar sites’ to demonstrate the possibilities. We provide lessons learned from the work and consultation with industry stakeholders (as referenced in the Chief Medical Officer’s report). We introduce our emissions tool which calculates NOx, PM and carbon emissions from NRMM, which has value for contractors, regulatory bodies and local authorities. This work is timely as DEFRA have called for actions towards reducing NRMM emissions. We demonstrate how to achieve reductions and recognise the need to support the transition and help quantify the benefits.

Abstract
The CURED emissions model predicts emissions of NOx from road vehicles.  It was first released in 2016 and widely used until 2020, when we determined that it was no longer required.  The CREAM emissions model predicts emissions of ammonia from road vehicles.  It was released in 2020 and is widely used, often being requested by bodies such as Natural England.

New evidence is now available which suggests benefits in reintroducing an alternative emissions model for NOx, as well as for PM10 and PM2.5, and updating the CURED and CREAM Models. CURED-4 and CREAM-2 will be released in summer 2023.  As with previous versions, both models will be free to use.

The presentation will explain why the updates are required, the new evidence used, and how predictions made using these models compare with previous versions and alternative approaches.
