Dear Mr. Blowers,

Re: Review of the Energy Saver Incentive.

Thank you for this opportunity to comment on the Energy Saver Incentive programme. Cosydome Limited is a new company working with innovative solutions to some common problems in the energy efficiency area.

We are also new to the VEET programme but already have high regard for the organisation and what it is charged with achieving.

I believe the operational mechanism that is VEET must be celebrated for its perceived relatively simplicity but effectiveness and successful execution of tasks and delivering results.

The area we work in, heat transfer around downlights and luminaire safety devices, remains an important activity within VEET as existing and new product initiatives are considered and administered.

The holistic approach we take revolves around a few simple fundamental principles that will help us express our beliefs for what the VEET Scheme could include;

INSULATION: Primarily the use of insulation in dwelling ceilings – To retain the 'produced' heat in the home during winter and minimising the elevated temperatures of the ceiling from entering the living space during summer saving on additional air-conditioning costs.

Energy Saver Incentive: there is no incentive for home owners to invest in insulation as most do not understand the benefit believing the home is probably already insulated. Home owners have also been put off this activity due to the bad press of the HIP programme. Insulation is an activity that the ESC could motive the home owner to do through the VEET programme and possibly deliver more benefit for the investment over other products.

CEILING VENTILATION: implementing ceiling ventilation technology to evacuate the elevated ceiling temperatures created by solar activity is vital. Any activity that can remove the heated ceiling space replacing it with the cooler outside air is critical to reduce the undesired heating of the living spaces caused though this heat transfer form ceiling to room. It is important to seal all luminaires to ensure the cool space air of the room below is not inadvertently drawn out of the room via the luminaire openings due to ceiling venting.

Energy Saver Incentive: Most people do not appreciate that in summer or winter the temperature contained in the ceiling space is acting like a big panel heater or cooling unit respectively. Right now there is no incentive for them to act due to no appreciation of the benefit. This is an activity that the ESC could facilitate.

LIGHTING: Replacing Halogen and incandescent lighting with new LED technology is a relatively simple activity that can be quantified in terms of electricity conservation. Unfortunately, the design of these devices and their placement typically in ceiling spaces sets them up to fail prematurely and often well inside the promoted warranty period.

As the ambient temperature elevates above 40degC, the electronic circuitry contained inside these devices starts to deteriorate reducing the efficacy and performance life. It is common for an average ceiling to reach temperatures of 40degC during autumn and spring, and well above 40degC during summer. Add to this the heat generated by the device when energised and then, if installed in a ceiling containing cellulose insulation (1:5 homes according to the industry), or misplaced insulation and the device is positioned to fail prematurely and potentially at risk of fire.

We welcome the new VEET LED additional evidence requirements introduced in June and are confident this will help reduce the occurrence of low quality devices that have been previously supplied to the programme.

From here the next development will be the use of Luminaires in-combination with a protective barrier that ensures adequate ventilation to the luminaire, protection from accidental covering with insulation and separation from loose-fill type insulation such as cellulose.

Energy Saver Incentive: Replacing existing lights with LED's is already a VEET activity that has just been revised to include more stringent product performance criteria. We believe that despite this additional product evidence, unless the luminaire is installed in an environment where all precautions are taken to protect the device from accidental covering with insulation, cellulose or segmented, and measures are taken to keep the luminaire at its coolest operational temperature, then even the best products will not deliver the performance life promoted.

SPACE VENTILATION: When the living spaces are protected from the heating or cooling caused from inadequate insulation and downlights the next activity is good ventilation to insure the occupants have fresh clean and temperature controlled air to live in. A temperature controlled recovery ventilation system will deliver this.

Fresh air is drawn into the home from the outside through a filter and heat exchange system. This exchange unit warms (or cools in summer) the incoming air by exchanging the heat in the outward stale air to the incoming fresh air (generally 80% efficient).

The obvious benefit of this system is that the investment made to heat (or cool) the home is not totally lost in the process of providing fresh air to the occupants. In winter the cooler introduced air is heated to 80% of the warmed living space and in summer the hot outside air is cooled down to 80% of the living space temperature. This is a significant energy saving system as it only relies on energy efficient fans to facilitate the air exchange – the heating or cooling is a simple 'passive exchange' process.

Energy Saver Incentive: Again, the consumer is not well informed about the benefits of good ventilation. If mechanical heating or cooling is being employed then opening the window is an expensive activity to introduce fresh air.

I trust the above list of activities assist your organisation to added innovative solutions into the very successful VEET Energy Incentive Saver programme.

I welcome the opportunity to contribute further to discussion groups and thank you again for this opportunity.

Sincerely, Cosydome Limited.
