Each Home Counts Report

Chair's Foreword

“Worst of all, and despite the good intentions of the Government and activities of responsible companies, there have been too many instances of poor quality installations being made by companies who do not have the skills, quality levels or core values required to operate responsibly in this market. An example of this was highlighted in a review2 by Peter Hansford, former Government Chief Construction Adviser, which focused on solid wall insulation installations and informed this Review.

In my response, my Review seeks to ensure that, in the future, conventional measures, such as insulation, always deliver the quality levels and outcomes that consumers have every right to expect, underpinned by the protection, service and advice so critical for householders. It also seeks to ensure that new opportunities offered through the roll-out of smart meters and other energy efficiency and renewable energy measures fulfil their potential in a way that informs and protects householders.”

What does PAS2030 focus on?

PAS 2030: 2017

An holistic approach, mandating design, specification, assessment, and installation competency.

PAS2030 & Ventilation Guidance

PAS2030

Why is Ventilation so important now? when houses have coped for so many years without it

PAS2030 The importance of ventilation - what does the new 2017 document recommend

What type of Energy Efficiency Measures, affect the Ventilation?

PAS2030 - Why Ventilate now?

In the past, traditional buildings achieved a 'healthy‘ moisture and ventilation performance, open fireplaces played a big role. A constant, vigorous draught (all year round, but especially when the fire was lit), will have removed moisture, and created a healthy home.

An example of Todays homes

• Current grant schemes and building works to save energy and reduce gaps in properties – lower fuel bills & save money

Loft Insulation

Cavity Wall Insulation

Double Glazing

All of the above measures reduce air leakage

Most Common examples we seeof Dew Points & Condensation

Windows are natural cold spots and can be a good indicators of future condensation problems in a property.

Examples of condensation

Condensation and mould growth examples within people homes

Table A.6 – Minimum levels of extract and supply ventilation when continuous extraction is used

NOTE 1 to Table A.6: Each habitable rom should be provided with minimum background ventilation of 3125 mm2 free area.

NOTE 2 to Table A.6: Where the window opening size is 10% of the floor area of the WC and is relied upon to provide extract ventilation then this should not be included in the sum of total extraction rate calculation.

4.2.5 Minimum acceptable ventilation requirements

PAS2030 Summary

If the air permeability is less than 5m3/(h.m2) we recommend PIV is included to meet PAS2030 designs (E.G if EWI is used we assume air tightness is less than 5m3/(h.m2))

Contractors must be given a full ventilation design before works commence.

Ventilation specific designs must be considered when an Energy efficiency measure reduces the air tightness of the building. Example measures include the following;

External Wall Insulation

Draught Proofing

New windows or Doors

New roofs

Internal Solid wall Insulation

Cavity Wall Insulation

Increase in Enhanced compliance e.g.

Mandatory minimum technical monitoring rates/frequency

Evidence of POMI/POPT i.e. proportion of the property treated with EEM

Evidence of suitability of design

Tips for ECO project Success

• Try and provide as much Information upfront to consultants and/or the industry specialists.

• Ask yourself, have we covered every criteria to everyone's requirements, avoid anything being refereed back to design stage and holding up works.

• If you are unsure on any design aspect….. ASK QUESTIONS! People will be happy to provide help within that relevant industry.
