    5. The challenge and opportunities of delivering heat networks

    5. 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.

    3. How Covid-19 has affected the way buildings are ventilated

    3. How Covid-19 has affected the way buildings are ventilated

    The authors of CIBSE's Natural ventilation guide discuss the best practice for minimising the risk of the virus as we emerge from lockdown


    Minimising the risk of Covid-19 in the built environment is the topic of the latest podcast by CIBSE Journal. The authors of CIBSE's Covid-19 Ventilation Guidance discuss the physics of virus transmission and how the infection risk can be minimised in buildings.

    Appearing on the podcast are Dr Shaun Fitzgerald, director at the Centre for Climate Repair, University of Cambridge; Eimear Moloney FCIBSE, director at Hoare Lea; Dr Chris Iddon, chair of the CIBSE Natural Ventilation Group; and Abigail Hathway, lecturer at the University of Sheffield.

    1. Ambient loop heating systems, sponsored by Daikin

    1. Ambient loop heating systems, sponsored by Daikin

    This podcast, sponsored by Daikin, looks at the concept of ambient loop systems and how they can help decarbonise heating in dwellings.

    Darren Manley, Daikin's solution business manager, sets out how heat pumps in apartments connected to low-temperature heat networks will deliver sizeable reductions in dwelling emissions under the SAP 10 calculation methodology.

    Manley explains how the system can deliver low carbon heating and cooling when connected to low carbon heat sources such as central air source heat pumps, waste-heat recovery and fifth-generation district heating.
