“We were very interested to note that our lighting load had the greatest impact on our power usage”.
Based on this knowledge from their electricity bill analysis, All Saints took action by replacing incandescent bulbs with efficient compact fluorescents (CFL) or light emitting diode (LED) bulbs as appropriate to the lighting required and upgrading their linear Fluorescents. They had already installed occupancy sensor switches in remote bathrooms to reduce power consumption from lights being left on.

The challenge of heating a large space efficiently is common to a lot of churches. The night store heaters in the main church and radiant heaters in the historic church are old and inefficient by modern standards. With rising electricity costs and Care of Creation motivating them, they were keen to explore alternatives. Far infrared radiant heaters are being considered.

All Saints considered the possibility of generating electricity on their roof. A quotation for installing photovoltaic panels was received. It is not cheap! The cost of a photovoltaic system is like paying your energy bills of the future, up front. Therefore, further cost analysis is required to assess whether or not the investment is worthwhile.
