Neil May - November 2018

 

Our co-founder, Neil May, sadly passed away on 12th November. His passion, knowledge & ability to motivate change will be greatly missed. His legacy of inspiring people to promote a sustainable built environment will continue. 

 

The STBA came into existence in 2011 following Neil’s discussions with other leading organisations – from Sustainability, Heritage and Industry – with concerns about the Green Deal. Neil continued to take an active role in the Alliance until ill health forced him to reduce his workload in 2016.

 

Under Neil May’s leadership in 2012 the STBA won backing from DECC to produce the Responsible Retrofit of Traditional Buildings, a report which built on an initial gap analysis backed by CITB and English Heritage. The report analysed the state of existing knowledge in the retrofit of traditional buildings, identified gaps in many areas of understanding, policy, skills & training, and made a series of recommendations to address these issues.

 

This approach has set the agenda for all our ensuing work, correcting standards where they were inappropriate for traditional buildings, improving policy in this area and providing guidance where it was completely lacking. The report led to significant funding from DECC for the development of an interactive Tool (the Guidance Wheel), and for work on moisture and thermal standards.

 

His work continues to form the basis of much of our work with much of the STBA guidance developed by Neil.

Practical responses to MEES

26th November 2018, Swindon

 

A workshop for landlords and portfolio managers.


Landlords and portfolio managers are finding it increasingly difficult to comply with  Minimum Energy Efficiency Standards whilst ensuring their properties are achieving real energy efficiencies. One of the reasons is that MEES are based around EPCs that often do not accurately reflect a building’s actual performance. It is important, therefore, to find an retrofit strategy that is both effective and also meets the requirements of current (and possible future) regulations.

 

The STBA and Fit for the Future, are collaborating to bring you an event which explores the practical responses to MEES. 


This workshhop takes place at the National Trust Head Office in Swindon on 26 November 2018 from 10.30 to 15.30.

 

During two contributory sessions, delegates will have the opportunity to share both the challenges they are facing, and the solutions being considered and implemented. The event outcome will assist the STBA to communicate concerns and solutions to the government.

 

Free to attend for STBA and Fit for the Future members. Guests £60.

APPG for Healthy Homes & Buildings White Paper

October 2018


The All-party Parliamentary Group for Healthy Homes & Buildings has launched its white paper: Laying the Foundations for Healthy Homes & Buildings. It highlights the need for a holistic approach to building design and renovation as one of the predominant and most urgent actions required by Government.


We are pleased to see, in recommendation 3, a whole house approach to existing buildings: "Making the renovation of current housing stock an infrastructure priority and developing plans for retrofitting that takes a holistic approach to maximising health & wellbeing.”

EPCs and the Whole House Approach

October 2018

 

Energy Performance Certificates are used as a tool that BEIS considers key in promoting energy efficiency improvements to buildings. With the increasing use of EPCs in policy it is vital that they reflect a true assessment of all types of buildings. As part of the STBA's ongoing dialogue with the government on building assessment and the whole-house approach, we have responded to the consultation on Energy Performance Certificates which closed on 19th October. Download the STBA response to the EPC consultation here.

 

The EPC is not a substitute for an energy audit and can only be useful as part of an enhanced homeowners’ report for the individual property. This would include assessment of the building type, condition and risk factors as well as a step-by-step retrofit/refurbishment plan – going into the future. 

 

We therefore urge you to read the STBA scoping study, EPCs and the whole-house approach. This report provides an overview of the key issues, constraints and opportunities surrounding EPCs. It identifies ways in which they could be better aligned with the STBA’s ‘whole-house’ approach, recommended in the Each Home Counts report.

French version of STBA Guidance Wheel

October 2018


The STBA Guidance Wheel has been adapted to give retrofit guidance for older buildings in France. CREBA (Centre de ressources pour la réhabilitation responsable du bâti ancien) has launched a French version of this freely available on-line retrofit tool, which highlights areas of concern for different types of construction and climatic zones. The French government are hoping to repeat the success of the UK where professionals have been using the Guidance Wheel for several years. The on-line tool assists decision making and increases learning about the whole-house approach to retrofit of traditional buildings.

 

La Guidance Wheel can be seen here and you can access the UK version here.

PAS2030 & PAS2035 and Each Home Counts

October 2018

 

PAS2030 and PAS2035 are due to be published in February 2019. The STBA has contributed to the development of PAS2035 throughout the process, and responded to the recent government consultation - where over 1,000 comments were received.

 

Our comments were minor as, in our view, the standard is of very high quality and needs little amendment before publication, though we would like to have seen a greater emphasis on repair prior to (or in place of) making changes. PAS2035 takes a risk-assessed approach to retrofit projects and traditional buildings will in most cases automatically be placed in the highest risk category, which should ensure that they are assessed by appropriately qualified surveyors. Significance of all traditional buildings (whether or not they have statutory protection) must also be assessed in line with BS7913.

The issue of qualifications is now being resolved and a level 5 diploma for Retrofit Co-ordinators is being developed by the FMB and funded by the CITB.  As most of the recommendations of the Each Home Counts review are now in progress, the EHC Implementation Board has now been disbanded.

 

 

 


Whole House Retrofit Toolkit

August 2018



The STBA is delighted to announce a 3-year project to test out the Whole House approach to retrofit, pioneered by the STBA and endorsed by Each Home Counts. This is being carried out under the Government’s Building Thermal Efficiency Innovation.

 

Based on 30-40 properties owned by social housing provider Melin Homes in South Wales, we will commence with detailed surveys of each house - including context and condition - before generating a bespoke programme of measures with detailed designs. These will address health and heritage in addition to energy use. The properties will be monitored for 12 months post retrofit, to check that the measures are working as intended and to ensure adequate indoor air quality.

 

Surveyor training will be developed alongside survey templates and training for installers.  Following further testing with the National Trust and RetrofitWorks, the process & supporting methodology will be released as a toolkit for industry use across the UK.

The Welsh Government recognizes the difficulties of retrofitting older buildings - July 2018

 

Our sustainability chairman, Peter Draper, joined Jill Fairweather of Cadw and Nigel Griffiths of STBA to meet with representatives of Welsh Government’s Decarbonisation & Energy Division and the Homes & Places team. There was genuine appreciation of the difficulties of retrofitting older buildings and a willingness to consider the evidence presented by the STBA and its members. There was also interest in developing detailed guidance to address the older housing stock in Wales, along the same lines as that which we developed for Bristol in 2015.

 

As we are now commencing our project to deliver “whole house” retrofit to 30-40 homes in South Wales (working with Melin Homes), this is very timely and the results can be used to feed into emerging policy in Wales. Welsh Government representatives pointed out that the Wellbeing of Future Generations Act obliges them to take a more rounded view of changes to the building stock and not to focus entirely on reducing carbon emissions from buildings “in use”. We therefore look forward to working more closely with Welsh Government as the whole house approach is developed.

EPCs and wider energy efficiency policy

July 2018

 

STBA’s director Nigel Griffiths joined National Trust, SPAB, CLA and IHBC to meet with Julian Critchlow, Director General, Energy Transformation and Clean Growth at BEIS. This meeting arose from a joint letter in 2017 which raised several issues around EPCs and wider government energy efficiency policy where it fails to consider adequately the particular needs of older buildings.

 

Ingrid Samuel of the National Trust explained the particular challenges they face with a large portfolio of private rented properties now subject to the new MEES regulations. Matt O’Connell of the CLA illustrated how some work which reduces carbon emissions can lead to a worsening of the EPC score, especially for off-gas properties. This underlined the conclusions of the recent paper from the STBA on problems with the EPC methodology (EPCs and the whole-house approach). We also pointed out that the recently launched online Energy Savings Advice Service (ESAS) did not seem to be consistent with the conclusions of the Each Home Counts report, which recommends a whole house approach.

 

Douglas Kent of the SPAB explained the risks of getting retrofit wrong and highlighted how the modelled u-values differ widely from actual measured values, as revealed by their research. He also stressed the importance of retaining the ability of older building fabric to breathe - to accept moisture and for this to be able to evaporate - when considering making any changes to buildings. 

 

Julian Critchley stressed that BEIS is still driven by the need to meet carbon budgets and that they needed a metric - this of course is likely to be carbon; as we know, this ignores many equally important aspects of buildings including human health and heritage - which, properly considered, should be part of a sustainable future. He also alluded to the importance of the government’s fuel poverty targets.

 

The meeting concluded with recognition from BEIS that a forum may be necessary for the detailed knowledge on this topic, held by the heritage sector, to feed into emerging policy.  We proposed that a group be formed with representatives of BEIS and the built heritage sector to facilitate this transfer of information, and BEIS undertook to look into this.



 


EPCs and the Whole House Approach

July 2018

 

The government is seeking views on Energy Performance Certificates (EPCs) - a tool that BEIS considers key in promoting energy efficiency improvements to buildings. This consultation is open until 19 October 2018. In April 2018 MEES (Minimum Energy Efficiency Standard) Regulations came into effect using the EPC as a compliance tool to mandate landlords to meet a minimum energy efficiency standard.

 

There are significant problems with using EPCs as a means of driving the policies for energy efficiency and we have been working with our Patron members, Historic England and the National Trust, to raise with BEIS our concerns and promote the necessary changes.

 

The EPC is not a substitute for an energy audit and can only be useful as part of an enhanced homeowners’ report for the individual property. This would include assessment of the building type, condition and risk factors as well as a step-by-step retrofit/refurbishment plan – going into the future. 

 

We therefore urge you to read the STBA scoping study, EPCs and the whole-house approach. This report provides an overview of the key issues, constraints and opportunities surrounding EPCs. It identifies ways in which they could be better aligned with the STBA’s ‘whole-house’ approach, recommended in the Each Home Counts report.

PAS2035 & Retrofit Training Pilot

July 2018

 

PAS2035 (specification for the energy retrofit of domestic buildings) is out for public consultation until 19th September) and is due to be published in February 2019. This will form an important part of retrofit going into the future. 

 

The STBA has been involved with PAS2035 to ensure the characteristics of old buildings are considered - and the initial draft will reflect this. However, it is imperative that we all get involved to ensure the end product – and the related training – are fit for purpose and filter down through all the layers of people involved with installing retrofit measures.

 

With appropriate training as a key element to success, the Federation of Master Builders, CITB & GLA are developing a retrofit coordinator course. This will enable contractors to deliver projects that are PAS 2035 compliant and covered by the Each Home Counts Quality Mark. Some of our members will be attending the pilot course in the Autumn. We look forward to their comments so that the STBA can give constructive feedback.

 

Over the next few months, we all have the opportunity to influence the final PAS2035 and related training. The STBA would like to hear your views and feedback as we respond to any areas of concern over the coming months.

 

Peter Rickaby gave a presentation (PAS2035: A new standard for domestic retrofit) at our STBA-SPAB Conference – this can be downloaded here.

New STBA report released


EPCs and the Whole House Approach

May 2018

 

Energy Performance Certificates (EPCs) are increasingly being used in UK policy as a means of driving the energy efficiency of the existing building stock. However, there are significant problems with this approach. The report provides an overview of the key issues, constraints and opportunities surrounding EPCs, identifying ways in which they could be better aligned with the ‘whole-house’ approach to retrofit developed by the STBA and recommended in the Each Home Counts report.

 

This study reveals that there are significant opportunities in the short term to improve clarity and understanding about the nature and limitations of EPCs. There needs to be a clear recognition that the EPC is not a substitute for an energy audit. Changes to presentation and the inclusion of key caveats concerning moisture, ventilation and heritage would also help to reduce the risks of misunderstanding and misuse.

 

In the longer term, it is becoming increasingly recognised that we need to deliver a sustainable built environment and not just a low carbon one, so a broader assessment is needed which has a wider set of goals - in other words, a Whole House approach, and an EPC can form an important part of the required assessment.

 

This scoping study has been prepared by the Sustainable Traditional Buildings Alliance (STBA) on behalf of Historic England and the National Trust. 


The scoping study can be downloaded here.

BBP's Guidance on MEES & Heritage Properties: 
Saving energy and protecting cultural value - May 2018

 
The BBP has today launched its latest Industry Insight, Minimum Energy Efficiency Standards and Heritage Properties: Mitigating risks through the procurement and interpretation of Energy Performance Certificates.

The report has been developed in collaboration with Sturgis Carbon Profiling, to support owners of heritage properties in meeting compliance requirements of Minimum Energy Efficiency Standards (MEES), whilst simultaneously recognising the special requirements of heritage properties.

The introduction of MEES has brought EPC ratings sharply into focus as an important indicator for investment and leasing decisions. However, with EPCs predominately designed to rate modern buildings, they do not always account for the traditional characteristics of heritage properties or propose the most appropriate energy efficiency recommendations.
    
Heritage properties often have many opportunities to improve their energy efficiency performance. However, without careful consideration of how improvement works will interact with their traditional characteristics, there is a risk of works having unintended consequences that compromise their historic value and cause physical damage.

Fortunately, many of these risks can be avoided by ensuring that property owners have a sound understanding of their buildings and that high-quality EPC assessments are undertaken. Guidance to support owners in this process is set out in the publication.

PAS2035 - March 2018


A publicly available standard for retrofit is under development at BSI. PAS2035 will cover the critical survey and design elements which had previously been included in PAS2030 - which is itself being revised and will focus purely on installation. We are delighted that PAS2035 has clear objectives including the avoidance of unintended consequences, the protection and enhancement of cultural and architectural heritage, and improving comfort, health and wellbeing.
 
A wider stakeholder consultation will be held in the coming months. We will share this with our network as it is critical that these objectives are maintained and followed through in the development of the standard, which needs to be in place for the next round of ECO - commencing in October of this year.


 


Building the Future: Qualifications Review

 - February 2018

 

Qualifications Wales has published its report, Building the Future: Sector Review of Qualifications and the Qualification System in Construction and the Built Environment. The report recommends some robust reforms that are intended to deliver clearly articulated, coherent progression routes from 14 to 19 for learners in Wales. 

 

The report also recognises that the knowledge and skills to work on traditional and heritage buildings needs to be embedded in mainstream qualifications throughout all stages of learning. This a major step forward for the historic environment of Wales and something that Cadw is actively promoting through its Strategic Skills Partnership Agreement with CITB, Historic England and Historic Environment Scotland.  

 

Qualifications Wales is inviting views on the options that they are proposing. Closing date 13 April 2018.

 

The full report, consultation document and international comparison report are available on their website.

Retrofit is at risk if not “whole house” approach

January 2018


Problems revealed in the article “Disastrous Preston retrofit” by Kate de Selincourt (in Passive House Plus magazine) flag up the consequences of retrofit without the ‘Whole Building” approach. Individual measures – such as efficient boilers – are, of course, beneficial across the board but unless the functioning of the building as a whole is taken into account, the result of more major retrofit will at best will be ineffectual and at worst damage the health of the building and occupants.

 

Image description

The STBA was established in response to concern over the “rush to retrofit” without consideration of the ‘unintended consequences’. The alliance of heritage, sustainability and industry practitioners was made possible by the joint desire for more research, enlightenment and influence (see the Origins & Development of the STBA), particularly in terms of defining and demonstrating practical whole building solutions

 

Our work on retrofit continues so that the failures, such as in Preston, can be avoided. The STBA has produced guidance and information including “Planning Responsible Retrofit” and “Whole House” . In addition, we were commissioned to produce the Moisture in Buildings paper published by bsi and we have worked with Bristol City Council to deliver their guidance on “Solid Wall Insulation”  and training programme for Bristol’s professionals and installers.

 

We are optimistic that, as the Whole Building approach is starting to be recognised in government policy and guidance, retrofit will improve and the need for different types of expertise for different building types will be acknowledged. Initiatives such as Each Home Counts should ensure that the one-size-fits-all mentality does not prevail.. However, there is still much work to be done and we shall continue to apply pressure for more change. Areas of ongoing concern are the assessment of buildings, EPCs and the SAP system for measuring energy rating.




Beautiful Buildings - the argument for beauty in a sustainable future - February 2018

 

It is not all about energy efficiency. Preserving beautiful old buildings that are functional and use high quality materials is a form of sustainability, say researchers. (See the full article on Science Nordic)


The research project, sustainable built heritage, by the Cultural Heritage, Transformation and Restoration research unit of The Royal Danish Academy of Fine Arts Schools of Architecture, Design and Conservation (KADK) recognises the value of beauty in a sustainable built environment.


Professor Christoffer Harlang states: “The understanding of what sustainable building is has become very restricted. There is a tendency to place a biased focus on the energy requirements of buildings. It is a huge problem because it often means that you either tear down buildings and build new energy-efficient buildings or rebuild beyond recognition. This means we lose the cultural heritage that is staring us in the face.”

 

Explaining ‘beauty’ Architect, Nicolai Bo Andersen says. “Beauty is not a matter of ugly or pretty. It is more a sense of meaningful cohesion, experienced through our senses and bodies. When a building speaks to us, it becomes sustainable, simply because we make a greater effort to look after it – because it is valuable to us,”

STBA comments on surveys as part of the buying and selling process - December 2017


The government consultation from the Ministry of Housing, Communities & Local Government - Improving the home buying and selling process in England - sought views on how to make the English process of home buying and selling cheaper, faster and less stressful.

 

As part of our response, the STBA questions whether building surveys should be part of the conveyancing period. The time restraints when securing the sale or purchase of a property often cause a rush into the almost tick-box exercise of procuring surveys and guarantees. These are usually for the comfort of mortgage providers. Even when a purchaser is keen for a full survey, they often end up with a less than satisfactory report.

 

“The issue arises in part because surveyors are often not specifically qualified to assess traditional buildings. The RICS Guidance for Surveys of Residential Property (2014) specifies that the surveyor needs to be familiar with the nature and complexity of the property type and the region in which it is situated, including: “Common and uncommon vernacular housing styles, materials and construction techniques; particularly important for older and historic buildings where the surveyor must understand the interaction of different building materials and techniques.” Many surveyors do not meet such a competence requirement. The need for a buyer to use an appropriately qualified surveyor (minimally BS7913) therefore needs to be made clear both to buyers and to mortgage providers when looking at traditional buildings.”

 

Our full response can be downloaded here.

 

The STBA's programme for 2018 includes a focus on the appropriate assessment of buildings. This would not be at the point of purchase but would form an ongoing homeowner's record to assist with understanding of the building type, significance, geographical context, condition and maintenance schedule. This would be important information essential when considering the essential 'whole house' approach for energy efficiency upgrades.

 

 


STBA Members' Workshop - Heritage, Environment & Industry: Common Ground and Conflicts‬ 

November 2017


Thank you to all those who joined us for our Heritage and Sustainability event at the end of November. The event got the ball rolling for this important programme by engaging with people from heritage, the environment and industry – but this is just the start of an ongoing discussion.

 

With the government encouraging industry to take the lead - in particular for retrofit - is it essential that we can find a common voice and alternatives to purely industry-led solutions. Only in this way can we create a truly sustainable traditional built environment.

 

Further Heritage and Sustainability events are planned for the future - and we hope this will give many more the opportunity to join us for these discussions.

Moisture and Breathability – 

ASBP and The Green Register event

November, Bristol - November 2017

 

On 9th November 2017, we took part in a well attended event on Moisture and Breathability This was organised by our Supporting Organisations, the Alliance for Sustainable Building Products and The Green Register.

 

In addition to our presentation on moisture in traditional buildings, Caroline Rye spoke about the SPAB Building performance survey, and the Bristol City Council talked about their Responsible Retrofit programme.

 

The event focused on buildings as part of a system in constant and dynamic interaction with people and the environment - not as standalone discrete entities. This interconnectedness means benefits, problems, solutions and consequences cannot be effectively addressed in isolation.

 

With energy efficiency as the main driver for retrofit, this event highlighted the importance of delivering effective moisture control, alongside good detailing, quality installation, consideration of product impacts and an effective ventilation strategy.


Moisture and breathability is part of the ASBP Healthy Buildings programme.

National Maintenance Week with SPAB 

17th to 24th November 2017


Efforts to keep our homes healthy and optimise thermal performance is often thwarted by inadequate building maintenance. SPAB are again celebrating National Maintenance Week with help and ideas for homeowners to preserve the fabric and character of their old buildings. The week runs from 17th November, culminating with National Gutters Day on Friday 24th November.



The Fighting Damp advice is available to download and this year they have produced a free, very handy, pocket-sized maintenance calendar. The SPAB Maintenance Calendar will help anyone who cares for a building to schedule simple, but helpful maintenance tasks throughout the year. Featuring fun cartoons and top tips, the calendar would be especially helpful as a give-away for local authorities and organisations working to promote good property care. More information - and how to order your calendar - on their website.



SPAB also runs an all year round Technical Advice Line where members of the public are able to discuss their technical queries over the phone with a member of their technical staff. The line is open Monday to Friday between 9.30am and 12.30pm on 020 7456 0916.

STBA & Heritage groups warn government over flawed approach to retrofitting older homes - November 2018

 

The STBA joined together with multiple heritage organisations, - including STBA members the National Trust, IHBC and SPAB - to write to the Government to emphasise that the one-size-fits-all approach to energy efficiency fails to recognise the unique nature of heritage properties.

The letter explains that policy to address the energy efficiency of the nation’s building stock is overly simplistic and designed from the perspective of modern construction and materials, ignoring fundamental building physics, resulting in inappropriate and potentially damaging measures.

 

According to the group, older homes built from traditional materials are being failed by the policy which gives homeowners inaccurate information on the energy efficiency of their properties and signposts them to potentially damaging retrofits. In the letter the organisations jointly ask to meet with Ministers to discuss the right solutions for safeguarding older buildings for future generations and to avoid further mistakes.

 

The conservation coalition writes that current policy to address the energy efficiency of the nation’s building stock is “overly simplistic” and “designed from the perspective of modern construction and materials, ignoring fundamental building physics, such as how traditional materials and structures ‘breathe’, resulting in inappropriate and potentially damaging measures.”

Private Rented Sector Legislation & SAP Updates - November 2017

 


The Domestic Private Rented Property Minimum Standard - Guidance for landlords and Local Authorities has now been published.


From April 2018 it will become illegal to let out a property with an EPC rating worse than “E”.

EPCs are based on RdSAP, itself derived from SAP - the Standard Assessment Procedure.


Following pressure from the STBA and other organisations, the recent updates to SAP included a much needed change in the default u-value for solid walls from 2.10W/m2K to 1.70W/m2K. Although this remains higher than the evidence suggests, this change is significant because EPC rating of some traditional buildings may improve as a result.


This change is also important because savings from solid wall insulation have been overestimated in the past due to the incorrect default value. Assessment of retrofit measures and packages of measures can  now be carried out on a more realistic basis.
