My work is in environmental consulting mainly related to building energy use,
such as low carbon heating off
the gas grid for CPRE, modelling heat losses from dwellings
Analysis of household electricity
use data for DECC and DEFRA, evaluating the
energy saving potential of a range of households behaviours for
DECC. Related projects include defining 'Cost Effectiveness' for Energy Improvements in Buildings for the Scottish Government.
I give workshops, sometimes paid and
sometimes not for community groups. These usually cover topics
connected with energy efficiency or about how to get the best out of
low carbon technology (such as heat pumps, PV panels or MVHR). I have also prepared some online material about the practicalities of living with carbon technologies
I spend a
good deal of time volunteering for local community groups, mainly:
- BSc (Hons) Open University 1st class (2010) in Environmental Studies
- MA (Hons) Cambridge 1st class (1984) in Computer Science and Engineering
My career has moved from computer programming, mainly systems and
graphics to environmental
consulting. These days I use a Mac Mini with Mac OS X and my main programming language is R.
- 2020-ongoing: Modelling low carbon heating systems to determine the most cost optimal solutions for retrofitting houses for BEIS.
- 2019-ongoing: Developing a method to determine the heat transfer
coefficient for a dwelling based on energy use data from smart meters
temperature data from thermostats.
- 2018-2019: A literature review to explore the variety of meanings of 'cost effective' in energy efficiency upgrades - what are the measures used and what is included or excluded and what time duratins are considered. The answers depend on who is asking the question, from householders or businesses to government policy makers.
- 2017-2018: Sourcing model parameters relating to energy
use and GHG emissions from processes ranging from heating building to
growing energy crops, for a model of UK greenhouse gas emissions
- 2016/2018: Quantifying heat loss through cavity party
walls. This had never been done before in homes that were in normal
occupation. We monitored temperature on both sides of the wall and
outside, and also heat flux in several places on one side the
wall. Then we had to develop a mathematical model of the heat transfer
and use statistical parameter fitting techniques to separate heat loss
to the outside from transfer across the wall to the neighbours home.
- 2017: Exploring innovation in solid wall insulation
for BEIS: conducting interviews with installers and prodoct
manufacturers, collating and synthesising the findings.
- 2016: Quantifying the benefits of home
insulation by comparing pre/post energy use in occupited homes, for an
insulation manufacturer. This also involved a great deal of data
cleaning and developing a methodology for the analysis, using air
quality data as well as energy use and temperatures. We found some occupants change
their ventilation habits substantially, affecting the energy savings.
- 2016: Quality assurance of inputs to a scenario
planning model used by DECC for industrial energy use and carbon
emissions to 2050. This involved collating and classifying
assumptions, summarising the structure and most importan assumptions
in different sectors for expert review.
- 2015: Analysis of energy savings in non-domestic buildings
for Innovate UK. This involved collating energy use data from a set of
50 leading edge buildings, identifying factors that contribute to good
and bad performance and common problems.
- 2015: Consulting for the Campaign to Protect Rural
England, about low carbon heating in rural homes, especially off the
gas grid. This involved interviewing householders about the measures
they had taken (or considered and rejected) to reduce energy bills
including insulation and heating systems. We were interested in
motivating factors , experiences, and savings made. The work also
involved modelling the impact of low carbon heating energy demands on
the landscape. You can download the report from CPRE: 'Warm
and Green; Achieving affordable, low carbon energy while reducing the
impacts on the countryside. See also my blog post Warm
- 2015: Consulting for the Department for Energy
and Climate Change: Costing Monitoring Equipment for a Longitudinal
Energy Survey. The aim was to evaluate options and costs for long term
monitoring of households for their energy use, behaviour and air
quality. This involved surveying the literature to find out what
equipment had been used before and collecting information directly
from researchers using surveys and a workshop. It seems there are many
aspects to consider in monitoring surveys from installing the
equipment to taking it away again. Reliability and ease of data
collection are as important as accuracy and resolution. Different
strategies are needed for households that do not have broadband
- 2014: Consulting for Department for Energy and
Climate Change: calibration of the NHM. The NHM (National Household
Model). The NHM is a software model that estimates the energy use in
UK homes according to their size, construction and insulation
properties. DECC use this model to predict the impact of policies like
the Green Deal. The calibration task is to compare the model results
with real bill data and adjust accordingly. Also the calibration
requires adjusting the housing stock model to reflect the known
status. There are more details on the CAR website.
- 2013 - 2014: Consulting for Department for Food and Rural
Affairs (DEFRA) and Department for Energy and Climate Change (DECC),
analysing Household Electrity Survey data. The task is to investigate
potential savings in use of electricial appliances by analysing a dataset
collected in 2010/2011 where 250 households had most of their
appliances monitored individually for a month.
The reports are published on www.gov.uk. The overall summary report is 'Powering the Nation 2'.
- 2012: Environmental consulting for DECC
on the energy saving potential of a range of
householder behaviours from turning down the heating thermostat to
installing an water efficient shower head, putting the lid on
saucepans or opening the fridge door less often. The project was lead
by Jason Palmer from Cambridge Architectural
Research You can download the report and associated spreadsheet with calculations from www.gov.uk.
- 2012: Environmental consulting for Department for Communities and
Local Government, researching and authoring the report 'DCLG
State-of-the-Art Review: Insulation and Thermal Storage
Materials'. The topic areas range from perforated bricks to vacuum
insulated panels and aerogels, from concrete to advanced phase change
materials for storage and from reducing heat loss to running
underfloor heating with off peak electricity. The project was lead by
Jason Palmer from Cambridge Architectural
Research and Ian Cooper from Eclipse Research
Consultants. A draft of the report is available on the CAR website.
- 2010-2011: Researching and writing Energy and
carbon emissions: the way we live today
- 2008-present: Website
construction and maintenance (both paid and pro-bono)
for several organisations, using wikis (pmwiki) discussion forums (smf)
and mailing list software (various).
- 2002-2009: Application design, development and maintenance for VBN
(Virtual Business Network) on their community network website
toolkit. Mainly VBScript, with a Microsoft-SQL toolkit but also some
VBScript these days, thank goodness). I also wrote system and user
documentation, recruited and trained new developers. VBN was bought
out by Sift in 2007 but I continued to do consulting work for them for
a few more years.
- 1989 - 2001: Systems software design, development and maintenance
for Smallworld GIS a geographical information systems toolkit, now
owned by General Electric. I started at Smallworld in 1989, almost
from the beginning of the company. I developed the graphics library
and the data dictionary for the Smallworld proprietary database as
well as implementing and maintaining the compiler for the proprietary
Magik language. Arthur Chance designed and implemented this language
and we both miss it even now. We worked mainly in Magik and C. I
documented the language and core systems for application
- 1984 - 1989: Before that I worked 5 years for Cambridge Interactive Systems, a
CAD-CAM company, mainly on graphics and user interfaces.
