Power Hours

This page contains the presentations from our ‘Power Hour’ events. In these fast paced talks we have a panel of speakers each with 8 minutes to present followed by a moderated panel discussion. We have a timer counting down from 1 hour and everything needs to be finished in that time!

Green Tariffs, PPAs, Offsetting and Insetting (Webinar)
25 September 2020

Climate change is changing our planet and society and we need to reduce our emissions fast. One way to do this is to for people to sign up to green energy tariffs, and offset their carbon emissions. Companies and organisations can sign up to renewable energy power purchase agreements and inset their emissions. 

But what do these actions achieve on the ground? What is their impact? Do they create positive change and reduce our greenhouse gas contributions? What are the advantages and disadvantages of acting in this way? Is it lot of greenwash?

Covid-19: Energy Use Now and Lasting Legacy (Webinar)
22 July 2020
 
There is no doubt that the energy performance of buildings has been pushed back further in the agenda of organisations and individuals to prioritise the health and well-being of people. But how can the energy and sustainability professional community reassert the importance of energy use given that we still have climate emergency and net-zero carbon targets to achieve by 2050? This webinar looks at both the challenges around Covid-19 standards and energy use, commissioning, the changes in consumption habits, energy purchasing and more.

Responsible Refurbishment (Webinar)
27 May 2020
 
Many organisations are signing up to net zero carbon targets. However, even if carbon neutrality in operation and the construction process is achieved, we will always be left with 'embodied carbon' in materials. For the first EPG Power Hour to be held online, our guest speakers tackled issues surrounding embodied carbon, and considered at what point you might refurbish a building rather than demolish and rebuild.

Getting Bristol Off the Gas Grid
18 February 2020
 
In February 2019 the Committee on Climate Change published a report entitled “UK housing: Fit for the future?” As part of that report they proposed that from 2025 at the latest, no new homes should be connected to the gas grid.
 
Preceding this, Bristol City Council had already become the first UK council to declare a climate emergency for the city, passing the motion unanimously. Consequently, the city council set an ambitious goal of making Bristol carbon neutral by 2030.
 
During this meeting - our first in Bristol - a panel of 4 experts gave their Power Hour opinions in short presentations, considering whether these goals are achievable, and how and or what the alternatives might be.

Net Zero Carbon: the short term and long term challenges and solutions
23 January 2020

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.

Come and find out more from our panel of 6 experts giving their Power Hour opinions in short presentations that will consider this challenging issue.

Getting Housing Off the Gas Grid
11 September 2019
 

In February 2019, the Committee on Climate Change published a report, entitled “UK housing: Fit for the future?”. An important part of this report is their proposal that no new homes should be connected to the gas grid from 2025 at the latest. Come and find out more from our panel of 4 expert speakers as they give their Power Hour opinions in short interesting presentations. These Power Hour opinions aim: (1) To provide insights into whether getting housing off the gas grid is achievable; (2) To provide insights into the views of the consultant, developer and utility providers; and (3) To provide insights into how and what the alternatives might likely be in the future. The names, affiliations and presentation titles of our panel of 4 expert speakers are described below:

Speakers
  • Jake Attwood-Harris, Hawkins\Brown Architects - "Getting Housing off Gas Grid"
  • Kartik Amrania, Sweco - "The Consultant’s View"
  • Aaron Caffrey, Ballymore - "The Developer"
  • John Marsh, Metropolitan - "The Utility Providers View"

Fuel Cells - Do They Really Work?!
14 May 2019
 
With the predicted fall in the carbon intensity of UK grid electricity, is there still a place for fuel cells to provide carbon free heat and power for the built environment? Come and find out more from our panel of 5 expert speakers giving their 'power hour' opinions in short presentations that will give an overview of the technology, a developer's view, what experience has been so far from two operators and what we might see in the future.

Heat Pumps - Do They Really Work?!
12 Mar 2019
 
Heat pumps are not a new innovation, however with the predicted fall in the carbon intensity of the grid they are quickly becoming the technology of choice for heating, hot water and cooling applications in buildings across all scales. Before we commit to this on mass in the UK, is it worth pausing and considering the risks and consequences based on what we know so far? Come and find out more from our panel of 4 expert speakers reflecting on their experiences so far and what the future might bring.

Operational Energy Use - Can Anybody Really Predict It?
15 Nov 2018
 
Operational energy predictions have long been an elusive task for the industry, challenging even the best designers, clients and operators. With increasing demand for accurate predictions of operation performance at the design stage, including recent changes in BREEAM 2018 and more demanding client briefs, we must ask ourselves the tough question: can we really predict operational energy performance?

Electricity Storage for Buildings
28 Sept 2018

Battery storage is becoming a regular feature in technical news bulletins with global investment in energy storage expected to reach $550Bn by 2050 and the price of lithium-ion batteries falling by 80% since 2010. This event looks at electricity storage in buildings, the challenges this entails, how it affects the power grid, and how industry, owners and occupiers can help!

Metering for Fame, Fortune & Happiness
July 12 2018

Can no one get metering right? We have to put them in, but does anyone check they're working or even look at them afterwards? Forget metering for Part L! This event provides essential insight for metering multi-let buildings, as “Part L metering” can be insufficient for tenant billing, particularly in relation to heat networks.
