Future of District Heating - 5 July 2017 (Cambridge) 

YEPG AGM - 11 July 2017 (London)

SKY GARDEN TOUR - 3 February 2017

By Serena Favatello, Sustainability Consultant at Hilson Moran

The CIBSE YEPG and the multidisciplinary engineering consultancy Hilson Moran organized a breakfast time Tour and Talk at the Sky Garden on top of the 20 Fenchurch Street building in the City of London.

Dan Jestico, former Head of Research & Development at Hilson Moran, talked through the challenges of designing efficient and effective features for this unique space.

The Sky Garden spans over three storeys at the 37th floor of the building and provides a 360° view across the City of London. Thanks to dynamic thermal modeling and CFD analysis, a smart system of automated louvers and apertures has been designed to naturally ventilate the Sky Garden and provide acceptable comfort level for the plants that grow in the space and the visitors. The roof has also been cleverly designed to incoporate a self bearing structure to the roof, provide external shading and guest photovoltaic panels.
The Sky Garden also contributed to the sustainable achievements of the 20 Fenchurch Street building, the ‘Walkie Talkie’ building, which achieved a 31% pass margin over Part L2A of Building Regulations and a BREEAM Excellent rating.
The integrated PV panels system is not the only sustainable source of energy at 20 Fenchurch Street, the building also incorporates the first Fuel Cell to be installed in a commercial development in the City of London, integrated into a Combined Cooling, Heat & Power (CCHP) system and support the Mayor of London’s policies on climate change mitigation.

An informative and energising start of the day, which left the attendants enthusiastic about the outcomes that a challenging and attentive building design can achieve.


YEPG BIG FAT QUIZ OF THE YEAR - 28 November 2016



We have hosted a series of talks, focusing on the Carbon Bites concept.

Each event saw two speakers covering the background (context; headline points of interest; current challenges & opportunities; common shortfalls, failings or misconceptions) and a project specific example (application; a case study or similar) in relation to a particular theme of interest for the Built Environment and Energy Performance in particular.

The topics, speakers and dates were as follows:

1. Legal Background of Building Energy Performance Requirements (09.03.2016) – where does all the regulation come from and how much of what we do is driven by it (EPBD, BRUKL, EPC, DEC, ESOS, etc.)
Hywel Davies + Netza Jack
The slides for the event are available here: Carbon Bite Night - Energy Performance

2. District Heat Networks (23.03.2016) – major area of focus in London and many other parts of the UK
Phil Jones + Chris Grainger 
The slides for the event are available here: Carbon Bite Night - District Heating Systems

3. Controls (06.04.2016) - basics & impact of, importance of end user interaction w. building and environment, criticality of good/simple/intuitive design

Nicola Combe + Ben Brakes The slides for the event are available here: Carbon Bite Night - Controls

4. Metering (20.04.2016) - sub-metering, TM39, BBP Toolkit, links back to benchmarks, control, understanding of building performance
Quentin Babcock + Peter Tse 
The slides for the event are available here: Carbon Bite Night - Metering

5. Post Occupancy Evaluation (04.05.2016) - importance of end user, understanding what worked previously and how it could be improved in the future
Tom Kordel + Lisa Pasquale 
The slides for the event are available here: Carbon Bite Night - Post Occupancy Evaluation 

6. Energy Performance Benchmarks (18.05.2016) – what's out there, they're really old and need updating, other sources (i.e. not just CIBSE TM46.Guide F), building specific benchmarks for clients
Maria Spyrou + Karim Dada 
The slides for the event are available here: Carbon Bite Night - Benchmarking


Carbon Bite Night in Bristol: Behaviour and Energy Management (06.04.2016)

This event was kindly hosted by AECOM and examined the often misunderstood role of behaviour in the energy performance of buildings, as well as the relationship between increasing automation and occupants' satisfaction. The slides presented by Phil Hampshire (Buro Happold) and Kevin Couling (AECOM) can be downloaded from here: Carbon Bite Night - Behaviour and Energy Management
