WHAT IS A HTT CAVITY?


What is a HTT Cavity?

• Term coined by DECC to identify properties that are

more difficult to treat for technical or cost reasons.

• Higher costs means that they were not treated in

earlier Supplier Obligations.

• Extending benefits of CWI to householders in hard to

treat properties is a Particular focus of the Energy

Company Obligation (ECO) and Green Deal.

– HTT Cavities a primary measure under CERO

• Defined in “The Electricity and Gas (Energy Companies

Obligation) Order 2012” Statutory Instrument.

• Further Guidance included in the OFGEM “Energy

Companies Obligation (ECO) 2012 - 2015: Guidance for

Suppliers”

The HTT Opportunity - Si

• (i) 3 or more storeys where each storey has cavity

walls;

• (ii) which a chartered surveyor has reported is not

suitable to insulate with standard insulation material or

techniques;

• (iii) which a chartered surveyor has reported is not

suitable to insulate without substantial remedial works;

• (b) a cavity within a cavity wall which is less than

50mm wide;

• (c) a cavity found in homes of prefabricated concrete

construction or with metal frame cavity walls; or

• (d) an uneven cavity formed in walls constructed of

natural stone or from natural stone outer leaf and

block or brick inner leaf;

Technical Notes

• Existing

– Internal Flues & Chimneys

– Technical Note -: drilling near flues

– Air Bricks and Ventilators.

– Safety Alert -: internal flues & chimneys.

– Flueless Gas Fires.

– Conservatories.

– Safety note : Core drilling.

• Proposed Drafts for review by Technical Committee

– Non Standard Buildings

• Narrow

• Partially filled

• 3 or more storeys up to 12m

– High Rise Buildings (above 12m)

– Commercial Buildings.

– Properties requiring remedial works


HTT Training

• Installation may require up skilling of existing

employees

– Assessors – competence to assess HTT cavities

– Technicians – ie non standard techniques

– Supervisors / technical moniters

– Sales/Customer Care.

• System Designer CWI Training Course -:

– Classroom.

– On Site.

• CIGA Training

– Working with System Designer’s

– Delivery to Installer Companies in association with

System Designers

HTT EXAMPLES?

10


HTT - Examples

• 3 or More Storeys

• Requiring substantial Remedials (4 hours)

• <50mm cavities

• Cannot treat with Standard Products or Techniques

– High Exposure/WP risks

– Timber Framed

– Partial Fill

• Steel or Concrete Frame

• Random Stone.


Identification -GD Assessment

• RdSAP covers 3 issues in relation to hard-to-treat

flaged on EPC – access, narrow cavity and exposure:

– Access issue is indicated for any façade where it is

not possible to safely pitch a 5 metre.

– A narrow cavity is indicated by a stretcher bond

brick pattern with wall thickness 220 to 250 mm.

– Exposure zones 3 or 4.

• Includes cases where at least 1 elevation is HTT.

• BUT:

– Does not map to ECO HTT definitions.

– Does not capture main addressable markets ie

remedials & Non Standard Techniques and Materials

High Rise

Building Report: (System Designer). (single page)

Suitability Assessment Form. (3x Pages)

High Rise Building - Additional Notes. (2x pages)

High Rise Building Assessment Version 4 RJS 04/04/2013


3 or More Storeys

• A building of 3 or more storeys of cavity wall is HTT.

• Includes basement with external wall exposed to the

air but excludes Lofts.

• Buildings up to 12m can filled under current approvals.

• In the case of buildings over 12m System Designer must

have a BBA approved procedure to issue height waivers

and additional CIGA requirements apply for issue of

CIGA HTT Guarantee.

• Can be notified under CWISC CP scheme.

12


Building Defects

• A building that a Chartered Surveyor reports

is not suitable to treat without substantial

remedials works is HTT

• Covers a wide range of defects and

structural issues.

• Standard construction and cavities, but CWI

cannot be installed until defects rectified.

• Includes removal of failed cavity or solid

wall insulation - but if covered by a

guarantee then savings from its

replacement cannot be claimed under ECO

• Additional requirements for sign off for

remedials - but standard assessment and

installation.

– Proposed to categorise by type or works.

Narrow Cavities

• A wall that has a section of cavity which is <

50mm wide is a hard-to-treat cavity wall.

• HTT Guarantee available where an approved

System used and can be notified under CWISC

CP Scheme.

• Currently some systems are approved down to

nominal minimum of 40mm.

• Each wall must be considered separately.

• CS report not required, but OFGEM looking at

evidence required to show that each elevation

claimed was <50mm.

– Assessment record with photographic

evidence?

– Monitoring through physical inspection?


Unsuitable for Std Prod.

• A Cavity that a Chartered Surveyor reports

is not suitable to be treated with standard

products is a HTT Cavity.

• Can be determined by whether a CIGA

Guarantee was available at 31/12/12

• Includes Partial Fill

• Includes Non Standard Constructions

– Steel Frame

– System Built

– Random Stone

• Cannot currently be treated or awarded a

CIGA HTT Guarantee.

• Not notifiable under the CWISC CP scheme.

14


Unsuitable for Std Tech

• A Cavity that a Chartered Surveyor reports is not

suitable to be treated with standard techniques is

a HTT Cavity.

• Can be determined by whether a CIGA Guarantee

was available at 31/12/12

• Includes Non Standard Techniques such as Lance

System

• CIGA HTT Guarantee available where:

– System approvals exist for technique

– Assessors and Technicians are trained by the

System by the System Supplier;

– Appropriate controls are in place to allow

identify properties to aid investigation if any

problems are reported.


FUTURE HTT DEVELOPMENTS?

15


Future Developments

• ECO Statutory Instrument imposes onerous requirements for claiming HTT cavities.

• In some cases includes report by a Chartered Surveyor and specific recommendation of a treatment

• Unproven, and work ongoing to develop alternative approaches that will provide greater safeguards.

• Centred on proposed BBA policy to assess and card HTT Assessors coupled with CIGA guidance and provision of CIGA HTT Guarantee.

• Requirement for CS hard wired in Si - so will require DECC change to legislation.

• Additional Issues:

– Monthly reporting by end of month following works.

– Uncertain monitoring requirements of Suppliers – evidence that Guarantee applied for etc.


Conclusion

• HTT cavities now defined

• OFGEM Guidance imposes some challenges but still

represents a significant opportunity

• Addressing all of the HTT markets will depend on R&D,

testing/approvals of systems and availability of

guarantees.

• CIGA HTT Guarantee now “live”

• Ongoing development of CIGA assessment and

installation templates and Technical notes.

• CIGA training being rolled out.

• Ongoing work to simplify ECO HTT requirements

• Updates will continue to be provided through member

communications and via the website:
