    Results of actions can be quickly seen as increased or decreased energy use to encourage responsible energy consumption.

Zero-energy school building uses Menlo3

When Århus Akademi refurbished the old classrooms and expanded the school they chose Menlo3. With an LOR that exceeds 80%, the lux level is 30% higher compared with the old installation. Combined with a lower wattage and lighting controls the result is up to 70% lighting energy savings.

Energy savings were of great importance for the new facilities because it is classified as a zero-energy building. The lighting is equipped with daylight controls, presence detectors, and an option for manual control, which enables the light to meet every need. Whilst a high lux level can help enhance energy and involvement during ordinary teaching it may be necessary to lower the light level when working on computers.

Some corridors are used for studying and even here Menlo3 has been used due to its excellent task illumination. With the focus on energy savings and a visual coherent architectural look and feel Menlo3 was also chosen for renovation of existing class rooms. The replacement was made one-to-one which makes it easy to compare the differences. In that part of the school the energy spend on lighting has been reduced by 50%, and during summer we expect savings to be rather 70% when the control system dims the light or turns it off as soon as artificial lighting is not needed.

The Sensa lighting control system gives occupants the flexibility they require, from a high lux level that enhances energy and involvement during ordinary teaching to lower light levels for computer work
