Ground source heat pumps for Reading


This ‘Reading Climate Forum’ event was held at on  20 November 2017, in the conference hall at RISC – 35 London Street, Reading.

Ground source heat for Reading


Rayner Mayer (Sciotech) – explained the need for ground source heat pumps in Reading, and the opportunity we have to take advantage of the chalk that underlies the town.

Chris Beales (Environment Agency) – talked about how groundwater is used, and some of the challenges faced in London by users of a different version of the technology.

Darren Wilkinson (Vexo International) – explained the technical solutions for making existing domestic heating systems a lot more efficient…which is very important for a scheme like the one being proposed.

Stuart Gadsden (Kensa Contracting) – explained how the closed-loop systems work in practice, and gave us examples of successful schemes for housing associations.

Pilot Project

We finished with a discussion about a pilot project, to test the technology in Reading. This has the support of the Reading Climate Change Partnership, and we are looking forward to seeing the results.

Reading’s Water Supply in a Changing World

Reading’s water supply in a Changing Climate

Michael Bright and Chris Beales – Friday 4th November 2016

“We live in a water stressed area. Learn about the impact of climate change on our water supplies with wetter winters and drier summers, where our drinking water comes from and what we can do to be more efficient in our water use.”

Chris Beales is a hydrologist working for the Environment Agency. He will talk about the current pressures on our local river system, and how change change is predicted to affect our rivers in the future.

Michael Bright is a water industry consultant. He will talk about how Thames Water supply water to our homes in Reading. He will discuss some of the challenges and what we can do as individuals to reduce pressure on our water resources.

We look forward to welcoming you to this, the fourth of our Autumn series of talks. It will be a lively and interesting discussion.

Low-Carbon Energy Techniques

Low carbon energy techniquesd

Rayner Mayer, Sue Roberts and Lee Webster – 17 October 2016

This is the third of our Autumn 2016 series of public talks related to climate change. Around a fifth of the UK’s carbon emissions come from domestic heating so reducing heat loss from homes and using energy efficient techniques will play an important part in meeting our climate change targets and keeping running costs down. Three speakers will provide an overview of the options and will describe some of the different techniques in detail.

Well-insulated and draught-proofed homes need to be properly ventilated so MVHR – Mechanical Ventilation with Heat Recovery – is important to ensure comfort and prevent condensation while minimising heat loss. Dr. Sue Roberts of energy assessors Ecomorph will describe how this works drawing on her experience turning her home into a ‘Superhome’.

Dr. Rayner Mayer of Sciotech Projects Ltd will explain how ‘heat pumps’ can multiply the energy in ‘green’ electricity to replace gas boilers as the UK abandons the use of fossil fuels. One example is the Student Services Building at Reading University which represents the current state of the art of low energy building and is heated and cooled by heat pumps using under floor heating. Heat pumps are widely used in air conditioning but studies suggest that Reading’s geology is particularly well-suited to exploiting heat held in the ground.

Lee Webster – Business Development Director of Aldermaston-based Anesco – the energy-efficiency solutions company – will give an industry view.

How to save on space-heating

Home energy saving talk

This is the first of our Autumn 2016 series of public talks related to climate change.
Tony Cowling and Ian Gough will be giving practical steps on how to save energy in our homes.

They will be giving practical advice on retro-fitting domestic energy-saving measures, including:

  • Insulation (loft, CWI, EWI, IWI)
  • Building fabric
  • Heating controls
  • Draught proofing
  • Glazing
  • Heating system upgrades
  • Appliances
  • Energy costs
  • Behaviours

Find out what’s right for you – from draught-stripping to aiming for PassivHaus standard – and how to save money, energy and carbon.

Climate justice and sustainable development – an interactive discussion

Climate Justice poster

Rayner Mayer – 29 June 2016

Dr Rayner Mayer (from Sciotech Projects and University of Reading) hosted a lively discussion on the ethics related to climate change. He introduced the following 3 topics, after which the audience debated the issues.

Climate Justice:

In the first section, Rayner introduced the concept of Climate Justice. He reminded the audience of the increase in extreme weather events, such as floods and droughts, associated with increasing climate change. These threaten lives and livelihoods across the world. He concluded that some regions are more affected than others; and that developing countries are disproportionately responsible for the greenhouse gas emissions that cause climate change, whereas poorer peoples are more vulnerable to the consequences.

Sustainable Development:

In the next section, Rayner discussed Sustainable Development. In simple terms: it is an obligation for the present generation to leave the world (biosphere) in a fit state for future generations. He noted that we have had successes so far, with millions of lives being saved as a result of the 8 ‘Millennium Development Goals’ (2000-2015). In the next 15 years we have the international ‘Sustainable Development Goals’ including: to end poverty, to end hunger, to reduce inequality and to ensure sustainable use of eco-systems. These include tackling climate change – if we don’t tackle the UN estimates that there could be up to 100 million climate refugees by the end of the next decade.

COP21 – the Paris Accord:

Finally Rayner talked about December 2015’s Paris Accord. In this, 195 individual nations have submitted ‘Declared National Contributions’, which are emissions reduction promises. These will be reviewed every 5 years. All countries signed-up to trying to prevent global temperatures from rising by more than 2 degrees Centigrade, however the current declared contributions could result in a 2.7 degrees temperature rise which is higher than that agreed in Paris. Religious leaders, including the Pope, are making strong calls for us to act on this global threat to life on earth. It is important that there are ‘top-down’ agreements like the Paris Accord, however it is equally important that we look at our own lifestyles and what are we going to do about it.

Climate Change impacts on food security – learning from past shocks

Climate Change and Food Security poster

Dr Jacob Bishop – 25 May 2016

Dr Jacob Bishop of the University of Reading University talked to us about “What is global food security?”:

  • future global food security which will require more than just increasing crop production
  • how global food might security be impacted by climate change
  • extreme weather events using past examples of food security failures as case studies
  • strategies being developed to reduce the impact of climate change on food
  • production and at other levels of food security
  • ideas of what can be done including increasing dietary diversity to reduce reliance on single crops.

Carbon Pricing – so polluters pay and people profit

Carbon Pricing poster

Clive Elsworth – 30 March 2016

On Wednesday 30th March the second in a series of ‘Reading climate forums’ discussed ‘carbon pricing’ – under which the cost of damage expected from global warming would be reflected in the price of fossil fuels.

Speaker Clive Elsworth from the UK branch of the Citizens Climate Lobby explained the ‘Carbon Fee and Dividend’ approach under which a fee would be paid when fossil fuels were imported or extracted by mining or drilling … and the money raised would be shared equally between all households.

Clive argued that fossil fuels must be priced out of the market – subsidies to renewables or energy efficient travel only reduce cost of activities so lead to more consumption. He said he had been inspired by climate scientist James Hansen’s book “Storms of My Grandchildren: The Truth About the Coming Climate Catastrophe and Our Last Chance to Save Humanity”.

Campaigner Justin Bowles then presented the views of three economists and a sociologist – saying that 90% of economists favour some form of carbon tax or carbon pricing to address climate change. He discussed the difficulties of setting a price today to reflect the risk of damage in the future.

Clive finished by hosting a role play exercise, where the audience were invited to try out some useful influencing techniques to try and sell the ‘Carbon Fee and Dividend’ concept to their local MP.

Extreme Events and Climate Chanage


Chris Beales – 16 March 2016

A series of ‘climate forums’ kicked off on Wednesday 16 March when Chris Beales, a local hydrologist and climate change specialist, discussed the links between ‘Extreme Events’ – weather events that can dramatically affect our lives, our homes and our communities – and climate change – which is often described by quite modest-sounding increases in global average temperature.

Extreme Events and Climate Change poster
The presentation showed that global and UK average temperatures are rising and are now at their warmest since records began, and the number of Extreme Events is increasing and records for temperature and rainfall are being broken.

Chris said that average temperatures are projected to rise significantly and we can expect to see even more Extreme Events – bigger and more frequent droughts and floods and heatwaves – which we need to prepare for.

Chris commented: “The world has important choices to make: if we significantly cut our use of coal, oil and gas … and meet the targets agreed in the Paris conference in December … we could limit the average rise in temperature to two degrees. Otherwise the climate could change very dramatically and the accompanying Extreme Events are going to be very difficult to deal with!”
