The Good Practice Exchange Case Studies Library will become the 'home' for all the case studies that are routinely identified as part of Wales Audit Office work. This includes case studies from our national reports for example Improving Access to the Countryside or Delayed Transfers of Care and more local reports such as our Housing Association Inspection Reports.
The Health Board identified inefficient and unreliable uses of energy at a 4,474m2 Community Hospital. These include heating systems, domestic hot water boilers, fiues, zone control valves and a building management system.
Saving through Tumble Dryer Replacements - Flintshire County Council - Llys Gwenfrwd, Croes Atti and Marleyfield Residential Homes
The Council's three Residential Homes had electric tumble dryers, for the simple reason that they were cheap to buy when the homes were being refurbished a few years ago. However, it was identified that the use of electric tumble dryers were not cheap to run.
South Wales Police installed software to automatically power down its computers after a specified period of inactivity. This initiative ensured that energy saving was achieved by reducing consumption. Computers turn to a 'low power state', and hence use less energy.
The Council had identified that electricity consumption could be reduced at their Llanelli Multi Storey Car Park. This identification emanated from a survey that was carried out during the first quarter of 2008.
The County Council installed twenty two voltage optimisation units in its larger sites:
The County Council installed 15 solar photovoltaic panel arrays throughout its buildings so as to bring renewable energy to the wider public. The arrays were installed in schools and libraries and each installation has a monitor located in the reception area, showing the current output and total output to date.
Gwynedd County Council has been aiming to reduce electricity consumption and Ioweing its carbon footprint. Its server room was at the end of its effective life and was not capable of supporting this commitment to energy efficiency. In addition, the Council had concerns about the risk of flooding as the server room was located in the basement ofthe building.
The Council's Energy team has launched a web-enabled heating control project in 70 schools to reduce energy usage and increase energy efficiency. This practice has proven to be highly effective.
South Wales Police has replaced existing T8 lighting in its Main HQ Building with more energy efficient T5 lighting. T5 retrofit lighting is a cost effective method of replacing T8 and T12 lighting. T8 and T12 lighting is, on average, 52 per cent more expensive to run that the T5 equivalent.
The Council has over the past eight years installed over three Mega Watts of biomass boilers at 11 sites.
