New Part L & F Consultation

Following months of speculation after the release of SAP 10.0 the Government has published the first of two Approved Document L (conservation of fuel and power) consultations and the BRE has published SAP 10.1. The release of these consultations has been anticipated for some time, introducing plans for a significant improvement in carbon dioxide emissions over current standards as well as including changes to Part F (Ventilation), air tightness and improving the ‘as built’ performance of the constructed home.

Energy efficiency requirements

In response to the new UK law which targets to bring all greenhouse gas emissions to net zero by 2050, the proposed draft Approved Document aims to provide the roadmap to future energy standards. Two options are being discussed on how to meet this target. The preferred approach is a 31% reduction in carbon emissions when compared to current standards (option 2), with the second approach suggesting a less demanding 20% reduction (option 1). These are considered to be stepping stones to the 75-80% reduction targets in the Future of Housing Consultation. Each option is provided with a potential specification in order to meet these requirements but is clear that a wide variety of approaches to meet these performance targets are expected.

Transitional phase

In the past new Building Regulation changes have taken time to be adopted, typically with a year grace period, and in some instances with phased developments able to use old Regulations for future phases.  To mitigate this, the consultation is proposing to encourage a quicker implementation of the new energy requirements, where any specific building yet to have any work commenced is to be built to the latest standards. The introduction of this stricter implementation may result in sites with the same planning consent being constructed to different Building Regulations.

Performance metrics

The new Part L is proposing four performance metrics for buildings to be measured against, which are as follows:

  • Primary energy target
  • Carbon dioxide emission target
  • Householder affordability rating
  • Minimum standards for fabric and fixed building services

It is proposed that primary energy will be the principal performance metric and carbon dioxide emissions will be used as a secondary metric. This would measure the total energy demand of the building, accounting for the whole heating fuel Lifecyle rather than just the heat demand of the dwelling.

The currently used fabric energy efficiency metric has been removed, with the proposal to encourage good fabric by retaining and improving the minimum standards for the individual fabric elements (walls, roofs, floors, windows etc).

Electric heating

The latest CO2 emission factors released by the BRE in SAP10.1 considers electricity to be less carbon intensive than gas. In combination with the proposed removal of fuel factors this allows electric heating to become more appealing. However, the new Approved Document is careful to note electric heaters are very expensive to run, and if introduced on a large scale it may have a significant impact on the National Grid.

To address the above issue, there is the proposal for the introduction of the householder affordability rating to reduce the risk of high energy bills for consumers, which will be based on the theoretical energy cost of the dwelling. As a result of the lower fuel factors for electricity, heat pump technologies are looking more promising as they have the same low-carbon benefits as direct electric heating, but can deliver heat much more efficiently overcoming affordability issues and grid-resource constraints.

Phasing out high-carbon fossil fuels

It is the Government’s intention to phase out high-carbon fossil fuels in new build housing developments by 2025 with the new Part L supporting this intention. The removal of fuel factors will no longer provide any relief to the high-carbon heating systems like LPG and oil, which was previously introduced to help developments that did not have access to mains gas. The new Part L does not look to ban these heating systems but it will make it considerably more difficult to comply with substantial mitigating measures being required.

Energy planning requirements

The draft Approved Document proposes to streamline the planning process to potentially prevent Local planning authorities from having the power to set their own energy efficiency standards in an effort to avoid confusion and inconsistencies across the country. The move to the higher energy standards required by the new Part L may lead to the Planning and Energy Act 2008 becoming amended or even made redundant.

Overheating

Following the 2018 Environmental Audit Committee it was recommended that the Government should create a new regulation to stop buildings being built which are prone to overheating. In response the Government is committed to consult around introducing a new overheating standard in an effort to manage internal temperatures but the details are yet to be released.  If you want to find out more about the risk of overheating we recently published an article about this on our website http://aessc.co.uk/blog/overheating/

Air testing

Consideration is being given as to whether developers should test all individual homes on a development instead of having the option to sample test, to avoid the potential of untested dwellings not meeting the required standard. Developers will also need to include all failed air tests within the pack of documents submitted to Building Control to indicate remedial works have been completed.

The air tightness testing scheme methodology is under review and consideration is being given to alternative testing methods such as a pulse test. The proposed new minimum standards for fabric performance for air permeability is being lowered from 10 to 8m3/m2.K at 50Pa.

Air quality

The proposed Part F changes will look to include mandatory opening restrictions on buildings in low air quality areas in an effort to promote healthy indoor air quality in new homes. Consideration is also being given to the noise output of ventilation installations as research has shown this to be one of the factors contributing to home owners turning off fans, resulting in poor air quality. The draft Approved Document is clear that systems should not be unduly noisy but further consideration may be given in a future Part E consultation.

Consultation

Currently this consultation relates only to the Building Regulations for England, which will remain open for comment until the 10th January 2020. If you wish to respond, please see the online survey at https://www.surveymonkey.co.uk/r/TQW8GQ9. The Government has released a preferred option in relation to timings with the proposal of mid/late 2020 for the new regulations to come into force. It is expected in the near future for Welsh Building Regulations to also go out for consultation.

We are still reviewing all the proposed changes and further articles will be released over the coming months to keep you up to date and assist you in preparing for the new Regulations.  Feel free to get in touch with us if you want any further information on this in the meantime at info@aessc.co.uk

The future of solar storage innovation and the influence of legislation

Can the ‘Smart Export Guarantee’ and complementary technologies continue the solar trend despite an axe to the feed-in tariff?

 

There’s no doubt that solar photovoltaic (PV) panels represent a huge chunk of renewable energy generation in the UK. In 2018, 3.9% of total energy consumption was generated by PV panels. The UK is the 3rd highest generator of solar energy in the EU, behind Italy and Germany, and the 6th worldwide (behind Japan, USA and China). Primarily, this is a result of falling costs as the technology becomes more established.

In 2010, the average cost for a 4-kilowatt (KW) PV array was between £12,000 and £14,000, whereas today it’s £6,000. However, despite this, recent decisions taken by the current government have thrown the industry into jeopardy.

House with PV
A 4 KW PV system has reduced in price by approximately 54% in 9 years

Feed-in Tariff

The Feed-In Tariff (FIT) was a government scheme that ensured consumers with renewable technologies received a fixed payment for both energy generated, and energy they exported back to the grid. The generation tariff was based on the assessed annual system output, and export tariff of 5.38p/kWh paid based on the assumed export of 50% of electricity generated back to the grid, regardless of actual export levels.

As of April 2019, the scheme was discontinued by the current government as it “did not align with the governments industrial strategy”, leaving prospective solar panel owners in turmoil. While it did not affect the ~800,000 homes who had installed PV since the scheme was introduced in 2010, with no replacement scheme in place new solar panel owners were facing the prospect of giving away excess solar energy for free.

However, upon consultation with the industry, the department for business, energy and industrial strategy have decided to introduce a new scheme.

Smart Export Guarantee

The Smart Export Guarantee (SEG) is a new scheme that is being introduced by the government from January 2020. It affects owners of renewable technologies with a capacity of up to 5 megawatts (MW) and is dependent on whether their main energy provider has over 150,000 customers. Technically, there is no right to receiving the payment if you were to use a very small utility company, however smaller utility companies might offer competitive tariffs in a bid to attract customers.

It is similar to the FIT in the fact that it will pay consumers for the energy they export back to the grid; however, it differs by paying a minimum rate per unit of energy rather than a fixed tariff dependent on the number of panels. In theory, this is meant to benefit small-scale renewable energy exporters as it will naturally allow the industry to become more market-oriented rather than subsidised.

Anyone installing solar panels between the end of the FIT (1st April 2019) and the start of the SEG in 2020 is eligible for the scheme, providing the installation is Microgeneration Certification Scheme (MCS) certified. Although at the early stages, the hope is that once the scheme is fully up and running it will be more generous than the FIT.

The first export tariff was launched in the UK on May 1st 2019 by Octopus Energy under the name “Outgoing Octopus” and offers a fixed rate of 5.5p per kWh (0.26p higher than the FIT) or a dynamic rate which changes every half hour and varies based on current demand. This, coupled with the continuing decrease in the cost of solar panels and an uptake in complementary technologies may represent a very appealing prospect for future clean energy exporters.

Complementary technologies – Solar batteries

One solution to the challenges faced by the industry could be solar batteries. These boiler-sized boxes can be installed in houses with a solar array, and can typically hold between 2 and 13 kWh at any one time. They offer great utility to PV owners in the UK, as unpredictable weather conditions often cause uncertainty about consistent power generation.

“The UK will need as many as 20 million ‘mini power stations’ to meet its target of net zero energy by 2050” Dr Andrew Crossland, an engineer with MCS’ Batter Installation Standard division has claimed. However, despite this, the UK government are set to increase the VAT for home solar-battery systems from 5% to 20%. All the while home coal supplies will continue to receive the 5% VAT rate. This is in direct contradiction to the governments ambition, and could push the take up of solar-battery systems back by years.

In spite of reduced government incentives for renewable technologies, the industry looks set to continue its growth as the technology develops in three areas:

1. Safety – It’s estimated that around one in 10 million lithium-ion batteries will fail in their lifetime at the cell level. However, poor installation and inadequate battery management systems (BMS) can magnify the risks.

Reputation is a huge driver of the development of the industry, and as the world becomes ever more connected through the internet, the quality of a company’s product and installation standards could be the difference between success and failure. This importance placed on safety standards will incentivise the whole industry to continue driving up standards.

2. Software – New energy management systems are using complex algorithms and artificial intelligence (AI) techniques to assess and manage individual home solar and storage. Through the use of data generated from smart meters, energy providers are able to monitor energy use in real-time, and can optimise delivery to provide consumers with the cheapest energy possible at any given time.

For example, Social Energy have created a system that dynamically manages energy supply every 5 minutes, enabling users to charge their solar battery using grid power when the price is low, and sell their self-generated power back to the grid when demand is high.

In short, this could produce the tantalising effect of making solar and storage systems so economical, they’d pay for themselves.This type of technology has the potential to radically enhance the effectiveness of the systems it manages, and could cause a shift in market share towards independent suppliers and away from the “big six”. However, for this type of technology is to become the mainstream a radical sea change in consumer behaviour is required.

Tesla Powerwall
The Tesla Powerwall has a capacity of 13.5 KWh, enough to last for over 24 hours in the event of an outage based on average energy consumption figures for a standard home

3. Cost – In 2010 when the FIT was introduced, the cost of 4 kW PV panels was roughly £13,000. Today however, a homeowner can buy a 4-kW PV array and 4 kWh solar battery for around £8500. This showcases a dramatic reduction in the cost of renewable energy system. Furthermore, the efficiency of PV panels has markedly improved as well, from around 4.11% on average in 2010, to 4.90%. In essence, this gives the consumer more energy for less money. If renewable technologies continue the trend of decreasing cost as the technology becomes more advanced, they will present a more viable option for energy delivery to consumers, and as such the uptake will be greater.

Conclusion

If the UK is to meet it’s target of being of being net-zero carbon by 2050, renewable energy systems for private homes must be embraced by the mainstream. It is uncertain how much damage has been caused by the scrapping of the Feed-in Tariff, however new legislation such as the Smart Export Guarantee give hope that it will be kept to a minimum.

Despite changes to UK legislation and the tax rate for renewables, the industry as a whole shows no sign of slowing down. Indeed, the charge of innovation is picking up pace, with solar systems providing safer, more efficient power at an increasingly lower price. Coupled with an uptake in complementary technologies such as solar batteries and electric cars, solar technology could become the primary method of energy generation in the future.

In summary, widescale uptake of renewable technology seems inevitable; it’s only a matter of time. Currently due to high start-up costs a simple payback for a PV and battery system is unlikely. However, with continuing reductions in panel and battery costs, anything is possible in the future. Once consumers can be convinced of a system’s safety and efficiency, solar systems will likely become the norm and assist with meeting the UK’s net zero ambitions to address the fight against climate change. However, the biggest obstacle remains the payback time for renewable systems.

Time will tell whether the trend in falling costs for panels and potentially increasing revenue for energy exports will account for the high start-up costs, however the necessity for this hurdle to be overcome has never been greater. With ambition and innovation, it is possible to achieve this goal.

Overheating

Can new builds rise to the challenge of Climate Change?

The recent record-breaking heatwaves across the UK, following the previous heatwaves of 2018, have brought the risks of overheating into the public eye, even though it has been declared as a public issue by England’s Health Protection Agency since 2011.

The negative impacts of exposure to heat can be seen when daily temperatures surpass just 16-20⁰C (Committee on Climate Change: CCC). The social and economic impacts can range from, poor thermal comfort, reduced productivity and wellbeing, to fatalities. In 2017 the average number of heat related deaths per year was recorded at around 2,000 (CCC). At present an estimated 20% of the UK housing stock overheats in standard summer conditions, therefore as climate change takes hold and extreme weather conditions become the norm, more fatalities will inevitably occur, unless significant action is taken to reduce indoor overheating. The Environmental Audit Committee expect the average number of annual heat related mortalities to reach 7,000 by 2050. It is concerning that the number of heat related deaths is likely to triple in 31 years, and should be mitigated against as far as possible. Furthermore, it is estimated that circa 90% of UK hospital wards are prone to overheating (CCC). This puts already vulnerable groups at greater risk. This is a clear indicator of how the impacts of overheating will be felt more severely as the effects of climate change become more apparent.

Building Regulations, which must be met by all new build properties, require a certain level of fabric energy efficiency (i.e. the efficacy of building materials in retaining heat) to be achieved as well as low carbon emissions rates. These standards dictate well-insulated, air tight structures to maximise thermal performance. A well-insulated property will both prevent initial heat gain, and trap existing heat. It is therefore crucial to find a balance whereby heat gains from sunlight are utilised in the winter, and minimised in the summer. Accounting for the effect of thermal mass at design stage is also important.  Homes with high thermal mass can be very effective at combating overheating, however, when the materials do not have sufficient time to cool down during extended periods of hot weather, the heat builds up and it is difficult to achieve cooler temperatures at night. This highlights the difficulty in achieving the balance required to maintain comfortable indoor temperatures year-round, especially where overheating is not considered early on.

Low & High Thermal Mass

However, where overheating is considered early in the design process, there are many strategies and features that can be implemented in new buildings to combat overheating. Overheating can be reduced by:

  • Limiting glazing area on southern facades
  • Installing external shutters, this can enable the homeowner direct control of the amount of sunlight entering the property
  • Incorporation of cross ventilation. This allows air to flow through the building and alleviate high temperatures.
  • Utilising louvres which encourage ventilation whilst also blocking sunlight
  • Extending roofs to provide shade over windows
  • Green roofs and walls which work through insulation, shade, evapotranspirative cooling and the albedo effect
  • Wider landscape design to provide local shading
  • Window design to allow secure ventilation on the ground floor

While some of the features detailed in the list above can be retrofitted, most must be considered at design stage if they are to be cost effective. Air conditioning is a popular retrofit cooling solution and, while effective, it is problematic as it:

  • Is expensive to install and to run
  • Is energy intensive
  • Can worsen overheating for surrounding buildings by moving the warm indoor air outside
  • Can intensify the urban heat island effect
  • Uses Hydrofluorocarbons as the primary refrigerant, a greenhouse gas more potent than CO2

Air Conditioning Cycle

Air conditioning is therefore contributing to the problem that it is being installed to help solve. This is a vicious and counterproductive cycle, as shown in the diagram above, that could be stopped with more effective early design solutions to overheating.

It is estimated that 80% of the current UK housing stock will still be in use in 2050, and therefore retrofitting will be necessary for existing houses. This need not be the case for new builds. Installing measures to combat overheating is crucial to avoid health issues and additional cost to homeowners. By highlighting overheating risks through updated Building Regulations, the government could facilitate changes to the new build market. Many of the passive measures to reduce overheating discussed in this article can be tested in dynamic simulation software, and some local authorities have even made it part of their planning process to consider future weather data. It goes to show that the technology is available now to combat current and future overheating, and placing this risk at the forefront of design could provide future proofed homes for generations to come.

Overheating is an issue that is not going away, it will continue to grow over the coming decades. Think about how uncomfortable you felt in your home on the 25th July 2019, these temperatures will soon become the norm. Without change now, both us and the generations to come will have little respite from the overwhelming heat. New build developments must be designed now to cope with the climate of the future and not the climate of the past.

 AES Sustainability Consultants can assist designers with analysing the risks of overheating now and in the future. If this is something you would like to discuss further please contact Silvio Junges on silvio.junges@aessc.co.uk.

Plastic Free July: My Honest Account

Plastic Free July: My Honest Account

Written by Charlotte Dutton

Last month, inspired by the BBC One programme: War on Plastic with Hugh and Anita, who over the series highlighted the shocking truths of our plastic consumption. I decided it was time to jump on the bandwagon and really reflect on what I could do to reduce my own impact. I have written my honest experience; it is safe to say it isn’t a fairy-tale ending with a plastic-free happily ever after account of things, but it has opened my eyes to where I and others can reduce waste.

At the start of the July 2019, much in the same way Hugh did in Bristol, I decided to look at all the single use plastic in my life, a bit like opening Pandora’s box! I discovered that committing to a plastic free life when out/ travelling is difficult without proper preparation, and the kitchen was somewhat of a disaster but I had a relative amount of success in the bathroom, with some plastic products lined up to change in the future once they are finished.

As a Graduate Consultant, on a Graduate salary, money is an obstacle. One I became painfully aware of whilst trying to reduce my plastic consumption during the weekly food shop. When trying to shop ‘plastic packaging free’, it meant I wasn’t able to buy 80% of my usual items, but the alternative options were out of budget.

Out and About

I re-used empty jam/honey jars as storage containers, invested in Tupperware of all shapes and sizes and bought an extra water bottle for my car. I drive a lot – usually to the beach for surfing, to the gym or visiting friends and I like to keep hydrated. I found, an extra bottle in the boot of the car stops me heading somewhere, realising I need some water and resorting to plastic. I don’t notice it’s there half the time, but since I did it at the start of July, I haven’t bought a single plastic bottle of water! (Mini Victory Dance) 

The Weekly Shop

Aldi had a limited choice of plastic free fruit and veg; broccoli, tomatoes, lettuce, bananas… all wrapped in plastic. When I looked at other supermarkets, I found it was often the case that the plastic free option was again, the more expensive option. Of course there are local grocery stores and farm shops, which have the added benefit of reduced air miles and supporting local business, but I found they still have an increased price tag, and aren’t easily accessible for everyone and usually closed after 5pm.

Veg not in plastic

I would gladly pay more for my food, shop locally and choose the plastic free options, but on top of rent, bills and fuel, I’d have very little money to put into savings or to enjoy life outside of work. My immediate thought is, it shouldn’t be this hard! It’s easy to see how we have such a reliance on single use plastic when the decision for many is as easy as ‘cheap and convenient’. The financial aspect of making a plastic free or more eco friendly choice is something that I struggled with in pretty much every decision I made, and I found it really frustrating.

Home Cleaning Products

Switching out dish brushes/ sponges for a natural coconut option, using a cloth and spray rather than one use surface wipes and using Ocean Saver refillable cleaning products. My housemate and I are also experimenting with less chemical based cleaners – citric acid, white vinegar, bicarb of soda – things your Nan definitely knows about, but they work! I could also purchase glass spray bottles, and refillable bottles for detergent, but this is a work in progress.

Eco-Coconut Scourer

The Bathroom

I invested in a solid shampoo and conditioner bar, ditched the shower gel products for solid soap/body wash bar options, purchased a traditional razor and made my own body scrub. You can find loads of ‘recipes’ for body scrub online, and you don’t need to spend much at all. The one I made is a mix of coconut oil, sugar, lemon and honey – which also doubles as an in-shower moisturiser!

Coconut Oil, purchased in a glass jar, has a myriad of uses; hair conditioner, make-up remover and shaving gel!

I’m still searching for alternative products for my skin care routine, unfortunately cost is the problem again! The products I currently buy, set me back no more than £10 every couple of months. The same products, in a plastic free variant (or in Lush’s non-virgin plastic, which I’m counting as re-usable) would cost me over £40 – A commitment I would love to make, especially as a huge fan of Lush’s products, but I can’t financially make that commitment at the moment.

Shampoo Bar

In Summary

The financial implications of making plastic free swaps can’t be overlooked, I think a lot of people my age are in the same situation and feel the same way. We want to reduce our impact, we understand that most packaging is now used just once and thrown away, which is damaging our environment, but why do customers have to foot the bill for this change???

John O’Groats to Lands End completed by Bradninch Castle Velo Club

AES and DALTEC would like to say congratulations to Pete Turner, Mark Staddon, Stewart Wall, Steve Trump, Mike Bamforth, Neal Hobbs, Kevin Haddican, Andy Butler and Steve Pearson who took part in JOGLE 2019 to raise vital funds for four charities.

AES and DALTEC sponsored the Bradninch Castle team, with Managing Director Fraser Hall, taking it one step further by driving the support vehicle for the epic journey!

The route took the team of 49 to 60 yr old amateur cyclists over 986 miles with 58,000 ft of climbing during the 14 days but all for good reason. They raised an impressive £6,563.54 (inc Gift Aid) for the following charities:

Hope Challenge Team with completed structure

Hope Challenge 2019

After months of preparation and fundraising, a team of 5 from AES (Ed, Jono, Row, Andy & Ross) headed up to the Peak District at the end of June to take part in the 2019 Hope Challenge, organised by and in aid of Habitat for Humanity GB. The challenge was to raise money for the charity, design, construct and sleep in a shelter, as well as taking part in a series of physical and mental challenges throughout the weekend.

Morning picture

Meeting at the office at 05:15 on Friday 28th June, the team loaded up the cars and trailer with everything that was needed to construct the shelter and set off for the mammoth drive to the Peak District. Arriving at the Hollowford Centre in the spectacular Hope Valley the team set about constructing their shelter before the allowed build time closed and judging began at 18:00.

Having prepared and practised constructing our fully recycled and recyclable shelter, it went up easily with time to spare, allowing us to suss out our strong competition. Our shelter featured a frame constructed of cardboard tubes previously used on rolls of artificial grass, a pond liner floor, a Perspex roof from a dismantled chicken coop and tarpaulin used to protect the aforementioned artificial grass. The resulting look was maybe a little more rustic than some of our competitors’, however it was structurally sound and survived the whole weekend. The judges were impressed by our shelter, and loved the little touches like the luggage rack made from leftover tubes, and the bee hotel made with the remaining bamboo dowels.

Structure in progress

Saturday began with the challenges at the Hollowford Centre – a water transportation exercise against the clock using bamboo stakes, guttering and twine which went smoothly and really got the team going, setting them up nicely for the following raft build. After time designing and constructing the raft, intrepid paddlers Andy & Ross took to the lake for a lap of the course, completing it in a record time, all the while remaining dry! (more than can be said for our opposing team – sorry Coins!). The final challenge of the morning was to make a fire, Bear Grylls style, and boil water for a hot chocolate – living in Devon with the abundance of wood burners and open fires, if’s fair to say we had this covered!

Structure being built

The afternoon arrived and it was time to begin our hike and memory challenge, in the sweltering heat. On the start line, 20 items (including Pi to 20 decimal places) were laid out for us to memorise and recite following the walk. We each memorised specific items and set off for the hike. At the first checkpoint, a stretcher carry challenge had been set up – 1 member of the team had to carried using only a bivvy bag and a climbing rope. Jono & Ed stepped up and, on a rope swing seat, carried Ross over the 100m course with incredible strength and determination. The hike continued up to the spectacular Mam Tor and along the ridge back to the Hollowford Centre, returning just in time for the BBQ and prize giving.

Ross being carried

A night in the pubs of Castleton celebrating with the other teams rounded off the fantastic weekend. Congratulations to the winners from the NHBC and to the great lads of Pantera Carpentry who came in second.

Finishing 7th overall and raising £2,454.00 for Habitat for Humanity the AES team headed home to Devon. Don’t worry, parts of our shelter have been re-used, with the rest recycled.

We had a fantastic weekend and send our thanks to Habitat for Humanity GB and Across the Divide for organising the event.

Celebration of buyout

Successful Completion of Management Buyout

AES Sustainability Consultants and Domestic Air Leakage Testing Energy Consultants (DALTEC) announce successful completion of management buyout

 

The founder of both companies, Jon Bodington, was keen to protect the businesses and its staff by giving the management team the opportunity to purchase the businesses so he could take a step back to pursue other interests.  The buyout has transferred ownership of both companies to AES Sustainability Limited whose new shareholders include Jon and Sue Bodington along with members of the senior management team: Fraser Hall, Anna Farmer, Alex Brooks, Silvio Junges, Greg Lock, Andrew McManus and Stewart Boyce.

Day to day management control of the companies is retained by the existing Directors; Fraser Hall, Anna Farmer and Alex Brooks.

AES Sustainability Consultants and DALTEC provide high quality advice and technical support throughout the lifecycle of a development, from land buying and planning stages right through to post-construction testing and certification. The two companies employ over 40 staff and service clients across the UK, including many of the top national housebuilders, developers and contractors.

“I have worked with Jon since 2005 and found him to be an inspirational, driven and focused leader.  After 14 years of building AES Sustainability Consultants and DALTEC I understand his desire to take a step back from the businesses and am happy to take up the reigns and continue to deliver his vision.Fraser Hall

Founding AES Sustainability Consultants in 2005, Jon Bodington soon became the Managing Director of a growing team and whilst he won’t be in the office day-to-day, he will still have an impact on the future of AES and DALTEC through his role of Chairman.

“I have worked in AES for over eight years now and am extremely proud of the expertise and dedication of the team.  We are very grateful for the passion that Jon has instilled in us all and the high standards he has set. 

Jon has always been the driving force behind the business but as we have grown the senior managers have taken on increasing responsibility for the day to day running of the company and shaping our future direction. 

Jon’s decision to take a step back will not impact on our future growth as we have strong relationships with our client base and a passionate team dedicated to delivering the highest standards of service. Jon set up the company to deliver honest, impartial advice to the construction industry and we will continue to do this for our clients across the UK, large and small.”  Anna Farmer

Legal advice to the founders was provided by James Orpin of Tozers LLP and legal advice to the management buyout team was provided by Evelyn Adfield of Porter Dodson LLP.

Constructing Clean Air

Today is World Environment Day, a day to raise awareness of the environmental issues. This year, we are encouraged to learn more about the air pollution around you, and how we can #BeatAirPollution.

Poor air quality within our towns and cities has been well documented over recent years, but how much the construction industry contributes to this, particularly when taking a whole life cycle approach is perhaps less well known. Air pollution is known to cause a range of illnesses including; an increased risk of lung disease, asthma attacks, Type 2 Diabetes… the list does go on. There are numerous sources of air pollution from driving and heating your home to larger scale commercial activities, such as manufacturing and construction.

What can and does the construction do to help #BeatAirPollution?

Design 

  • Specify and install energy efficient building solutions, systems and equipment reducing SO2 and NOx associated with the burning of fossil fuels during the operation of the building.
  • Travel methods for the development users must be considered as early as possible to ensure the development is designed to enable significant reductions in car-based travel.
  • Where car-based travel is required; specify electric car charging, car sharing spaces and limited car parking to encourage the use of alternative or more sustainable transport modes.
  • Sufficient ventilation in buildings to reduce indoor air pollution.
  • Specification of non-toxic paints, varnishes, woods and solvents, to reduce emissions from these products throughout the lifetime of the building.

Construction

  • Construct responsibly by reducing traffic to site through efficient procurement
  • Replace generators, excavators, bulldozers, mobile cranes and loaders etc. (otherwise known as Non-Road Mobile Machinery or NRMM) with more efficient models and gain NRMM certification through the energy saving trust. There are now some companies producing electric NRMM and battery storage for generators to help reduce diesel usage on site.
  • Devise robust control measures for dust to limit its distribution both on and off site.
  • Use non-toxic paints, solvents etc. as much as possible.
  • No burning of materials on site.
  • Testing the new buildings indoor environments to ensure levels of formaldehyde and VOCs are met.

Handover and Occupancy

  • Commission building systems, to ensure that they are working and being used correctly to minimise any detrimental impacts on both the internal and external air quality of the development.
  • Building owners and managers to be provided with robust travel management plans to ensure that car-based travel is reduced as much as possible.
  • Building Handover and User Guides to ensure that facilities managers and users are able to use the systems correctly.

The construction industry can go a long way in helping reduce air pollution, by constructing buildings to help reduce air pollution and minimise impact of construction activities. In essence, the industry has a large role to play to help construct clean air for our future generations.
