The key to the success of a solar-thermal installation is all in the sizing — just one of the problems which is taken away from the designer by using an Andrews SOLARflo system.

Solar thermal as a source of renewable energy

In a building with the right energy balance, using solar energy to produce domestic hot water can meet the 10% renewable requirement. Yan Evans gives practical advice how to get the best from this technology.

Priva helps Dublin school go greener

Monitored energy results for the first year of operation of the Archbishop Ryan School in Dublin indicate that its energy performance is twice as good as that of a school constructed to meet the good-practice targets outlined in CIBSE Guide F. Energy consumption was monitored by the Priva control system installed by Temperature Control Systems to optimise the operation of lighting and heating systems in response to the benefits of passive solar gain, daylight and natural ventilation.

The role of pumps in delivering energy savings

There is very little to be gain by improving the efficiency of pumps to reduce their energy consumption. Much more can be saved — about half — using speed control and the better design of systems, as John Veness explains.

Wilo shows the way to reduce pumping costs

Replacing pumps in 12 plantrooms at Derriford Hospital in Plymouth with equivalent pumps from Wilo’s energy-efficient range will reduce energy consumption by £70 000 a year — a useful dent on the electricity bill of over £1 million a year.

The third stage of the Grundfos Energy Project to encourage the use of more efficient pupmps is under way.

Grundfos energy project enters its third phase

Grundfos is moving into the third phase of its project to increase awareness of how using efficient circulators can significantly reduce carbon-dioxide emissions. The project started in 2005 with the launch of the world’s first A-rated domestic circulator — the Alpha Pro.

How Grundfos aids pump selection

To help customers decide which pumps would best suit their needs, regardless of the application, Grundfos provides a range of selection tools —which have become industry standards. These aids are constantly reviewed and updated to keep them relevant.

parallel pumping
Parallel pumping enables installed power to be halved compared with full duty/standby — and even greater savings can be achieved by controlling pumps to deliver the required flow.

Delivering energy-efficient pumps

Designing systems with duty and standby pumps that can both meet maximum demand is must not efficient. Wayne Rose explores other approaches.
