Utilisation of Digital Twin Technology to Enhance Building Performance: 31/03/22

CIBSE Young Energy Performance Group are pleased to invite you to our upcoming online event; "Utilisation of Digital Twin Technology to Enhance Building Performance"

Join us for a discussion around how digital twins can be integrated effectively into both the design and operational phases to optimise a buildings energy performance. This CPD will include actual case studies as well as software demos to show why digital twins are critical to improving the energy efficiency of the built environment.

The topics include:

  • Using digital twin technology (IES ICL suite) to design and integrate key elements of a smart energy network for large scale retrofits as part of energy performance contracts on university and public bulding estates.
  • Using digital twin technology during operational phases after large scale retrofits to support measurement and verification, performance commissioning and controls optimisation. Therefore ensuring energy reduction targets are achieved.
  • Improving the design, delivery and operation of heating and cooling systems in both buildings and heat networks through hydraulic system optimisation

The speakers are:

  • Tunde Olaoye, Sector Director of Smart Energy Systems at SSE Energy Solutions
  • Chris Davis, UK Sales Manager at Hysopt
  • Brian Vanheel, Sales Engineer at Hysopt

If you are interested in attending this event, please find out more information and sign up at our Evenbrite page. 

If you have any topics you would YEPG to cover in future discussions, podcasts and events. Please email them to [email protected]

More upcoming events will be announced both here and on our Eventbrite page. 



Carbon Bite Night Series 2021

1. Humidity control on Indoor spaces (27/10/21) - Given the recent pandemic, more attention has been shifted towards ventilation practices. However Humidity control in the built environment continues at times to be neglected. The three speakers discuss active and passive measures available, and the following topics: 

  • How can you save energy & cost?
  • How does Humidity affects indoor air quality, comfort & the spread of COVID-19 ?
  • Available technologies for Humidity control?

​Rossella Perniola + Dave Marshall-George + David Black
The slides for the event are available here: Humidity control on Indoor spaces

This was YEPG's first in-person event since the pandemic. Thanks to WSP for hosting!


2. Quality Assurance of Heat Networks (04.08.2021) - The recent update to CP1: Heat Network Code of Practice (CP1 2020) places a much larger focus on verification of heat network performance. To meet these requirements and support the decarbonisation of the sector, it is clear that the role of quality assurance will become more important during the design and delivery of new schemes. This discussion will aim to highlight the importance of heat networks quality assurance and demonstrate quality assurance processes. Our speakers will also discuss the impact of quality assurance of heat networks from a housing developer and mechanical contractor's perspective

1. Demand side response (17.05.2021) - Given that we are moving towards an electricity powered future to achieve Net Zero targets, can our current grids accommodate the emerging demand in electricity as well as the anticipated unpredictability from increased renewable generation? With the increased uptake of storage solutions as well as onsite generation, how can these be utilised and integrated with the grid to decrease electricity bills and better manage the peak electrical loads? Speakers at this carbon bite night discuss the topics above.

Carbon Bite Night Series 2020

1. The role of 5DH in the UK's path to net zero (30.04.2020) - 5th generation district heating has gained a lot of attention in the UK industry recently, with improvements in technology and updates to key regulations driving the use of heat pumps. However, design philosophy and implementation of this technology remains unknown to many, as few 5DH networks are currently operational in the UK.

2. Taking commercial offices to net zero carbon (01.05.2020) - The release of the LETI Climate Emergency Design Guide in January and the UK Green Building Council targets for Commercial Offices in April have put Net Zero Carbon front of place in commercial office design. But how do we actually go about delivering Net Zero Carbon commercial office buildings? In this event speakers discussed how to achieve Net Zero Carbon in design, operation, and retrofit of commercial assets.

3. The impact of DHW temperatures on energy performance (12.08.2020) -
 Domestic hot water (DHW) temperatures have long been a discussion point in the industry, due to the impact of this set point on resident comfort, energy performance and public health. As the industry focus moves towards electrically generated heat, the impact of DHW temperatures on energy performance becomes increasingly important, and there is increasing momentum to reduce these temperatures. In collaboration with the Society for Public Health Engineers, the three speakers discuss their experiences and expertise on the factors that influence DHW temperatures and current research that will help to shape the conversation going forwards.

4. Design to mitigate overheating in the built environment (02.12.2020) 

CIBSE YEPG & EPG Joint Event

Net Zero Carbon: The Short and Long Term (23.01.2019) - Having declared a Climate Change emergency what do we do now? The Committee for Climate Change suggested that all new housing should be off the gas grid by 2025. If we wait until 2025 does that simply make the net zero by 2050 all the more difficult? What practical steps should be taken in the short term and what will happen in the long term? The Energy Performance Group has assembled a top team of speakers including an Architect, an Engineer and a Developer to consider what concrete steps can be taken in the short term to address this issue. The Young Energy Performance Group have done something similar but focused on the longer term issues.
