Countdown to net zero: tackling whole-life carbon in air conditioning

Four industry experts join the Journal podcast to discuss the challenges of reducing operational and embodied carbon in building cooling systems. Space cooling accounted for nearly 16% of the global building sector’s electricity consumption in 2020 according to the International Energy Agency. Global demand for space cooling and the energy needed to provide it will continue to grow for decades to come, with the demand for cooling expected to triple by 2050. This podcast, sponsored by Daikin, discusses the challenges of decarbonising cooling across a building’s lifetime with four expert guests discussing how best to reduce both operational and embodied carbon. Subjects tackled include training, embodied carbon calculations, and the role of digital twins in managing building data. The panel concludes that engineers must also consider occupant comfort and flexibility in building design to reduce the requirement for cooling. The guests on the podcast, chaired by CIBSE Journal editor Alex Smith, are: Carl Collins, head of digital engineering at CIBSE Matteo Dall’Ombra, product commercial Daikin UK Clara Bagenal George, an associate at Introba Andrew Mitchell, head of sustainability operations director at Mace

People, energy and performance: a new approach to office lighting

Covid has radically altered the way we work, with a hybrid approach seeing people spending as much time working from home as in the office. For companies to persuade people back to the office workplace and attract new talent, they now have to offer attractive, comfortable spaces that provide opportunities for creativity and collaboration. Lighting has a large part to play in making people feel healthy and comfortable at work, whether it’s through human human-centric lighting or access to daylight and exterior view. Of course, any lighting strategy has to minimise the energy used. With lighting making up around 17% of energy use in an office, it’s imperative that designers look at strategies that minimise energy use, therefore reducing costs and the carbon in their projects. Our podcast will explore the current trends in lighting around design, people and performance and will look at how automated controls can help reduce energy use. Guests discuss the key trends in commercial lighting, including tuneable white light, flexibility, access to daylight, the digital transformation, and how automated controls can help reduce energy use. The guests also emphasise the importance of refurbishing and the reuse of materials and look at CIBSE’s TM66 guide to circular lighting. The guests appearing in the podcast chaired by Alex Smith are: Miguel Aguado, marketing and technology manager at Lutron Electronics. Juan Ferrari is a lighting designer who leads the London Lighting Design team at Hoare Lea. Bob Bohannon, who is head of policy and academy at the Lighting Industry Association. He is also a past president of the Society of Light and Lighting, and led the team that wrote CIBSE’s TM66 on circular lighting.

Podcast: Designing new pump technology into existing spaces

How significant returns can be generated by upgrading building services infrastructure to achieve carbon savings and operational efficiencies The increased focus on whole life carbon in the design and procurement of buildings is having a seismic effect on services procurement and design. The carbon cost of embodied energy in existing buildings is leading many developers to refurbish their buildings rather than build from scratch. This podcast, sponsored by Grundfos, looks at the growing influence of whole life carbon calculations on design and procurement, and the importance of 'upfurbishing' existing buildings with energy efficient systems and designs. Guests Edmund Vaughan, from ChapmanBDSP, and Glenn Miller and Linda Dingley, from Grundfos, discuss the challenges of calculating whole life carbon in buildings and equipment. They also look at the balance between reusing equipment to save embodied carbon and specifying new efficient plant and materials that cut operational carbon. The podcast looks at how manufacturers are providing more environmental data to help consultants make more accurate carbon assessments and discusses the importance of calculating whole life carbon at the start of the design process. The importance of metering existing buildings to understand the performance of existing systems is discussed with a reference to Nabers UK, which requires property owners to rigorously monitor buildings to ascertain system performance. Details of the guests in the podcast, chaired by CIBSE Journal editor Alex Smith, are: Linda Dingley, senior marketing specialist at Grundfos Glenn Miller, regional product and solutions manager at Grundfos Edmund Vaughan, operations director at ChapmanBDSP

Podcast: The benefits of distributed pumping in HVAC applications

In this podcast, sponsored by Grundfos Pumps, we discuss the benefits of distributed pumping in HVAC applications. Danny Staerk and Glenn Miller look at how this approach helps save energy, simplifies balancing and reduces commissioning time. The Grundfos distributed pumping solution distributes chilled water in HVAC applications without the need for pressure-regulating valves. Staerk and Miller explain how savings of up to 54% in pump energy can be achieved by replacing throttling valves with intelligent pumps in HVAC retrofits. They explain how intelligent pumps perform to the exact building load meaning there is no need for balancing or rebalancing through the building's lifetime and discuss how data available from the pumps offers insights into building performance that are not possible with valves. Guests in the podcast, chaired by CIBSE Journal editor Alex Smith, are: Glenn Miller, product and solutions manager at Grundfos Pumps who joined the company in 2005. He has a strong electro-mechanical background and extensive experience of delivering solutions to the commercial building services industry. Danny Staerk, leads solutions manager for HVAC and CBS Systems at Grundfos Pumps. He joined Grundfos as controls product manager having previously worked supporting wind power management SCADA systems.

Podcast: The challenge and opportunities of delivering heat networks

In this podcast, sponsored by Grundfos Pumps, we discuss the challenges and opportunities of realising the government’s ambition of significantly growing heat networks in the UK. The Committee on Climate Change has recommended that up to 18% of heat demand should be met by heat networks by 2050, and it has emphasised the importance of connecting non-domestic buildings to networks. It states that these should account for 53% of total heat delivered by heat networks by 2050. Grundfos’ Glenn Miller and Kim Hansen will share the Danish company’s extensive experience of district energy networks, while CIBSE's Julie Godefroy looks at the government policies that are being used to encourage the uptake of heat networks. The podcast will look at the influence pumps have in overall system performance and the role they play in the efficiency of individual components in a district energy system. Guests in the podcast chaired by Alex Smith are: - Glenn Miller, product and solutions manager who has worked as an engineer in construction since 2005. - Kim Hansen, business development and solutions manager in District Energy, who has been specialising in developing digital solutions for district heating networks that are driving improved energy efficiencies. - Julie Godefroy, who is the head of sustainability at CIBSE and has been involved in CIBSE’s response to the government's proposals on growing the number of heat networks in the UK.
