The Anglican Dioceses of New Zealand are comprised of 9 cathedrals, nearly 900 churches and halls, more than 400 clergy homes, and 80 community facilities nationwide, ranging from retreat centres and aged care facilities through to schools and Whare Wānanga. As caretakers of these facilities we believe that faithful stewardship of God’s creation, for the benefit of everyone who share’s in it, is at the heart of the Auckland Diocese Sustainability Surveys.

The Sustainability Field Worker for the Anglican Diocese of Auckland carried out in depth Building and Operations Sustainability Surveys of ten parishes between 2012 and 2015. The Sustainability Flow Chart sets out the process that was followed in order to improve their sustainability. Here we summarise some of the findings from the parishes that have been surveyed. You can read more highlights in the Sustainability Newsbites for each of the churches involved.

Church Electricity Proportions of Use Chart

This chart represents four different churches that were surveyed. It shows what proportion of their total annual cost for electricity was spent in each of three areas – continue reading…

Top Tips on Heating – The type of heating you choose should suit the location in which the heaters are used. Some heat objects and bodies (radiant heaters), while others heat air (heat pumps) or are a combination (convector heaters). Modern units are far more efficient at delivering heat than old heaters, particularly for far infrared heaters, which suit large church auditoriums. Heat Pumps are a very efficient heating technology but see the “Radiant Heating for Churches” document for some pros and cons. The DIY Heating survey has recommended actions for improving heating efficiency.

Top Tips on Lighting – The lighting industry is currently going through a major transition from old inefficient incandescent technology to new very efficient Light Emitting Diode (LED) technology. During this phase prices are falling rapidly, but it is important to choose fittings and lamps of reputable brands to achieve savings. Improving efficiency by using occupancy sensors and / or timers is particularly helpful for remote rooms such as bathrooms in church facilities. Free natural daylight should be used wherever possible to save on lighting, which can be a substantial proportion of a church’s Base Building Load (see the Chart above and continue reading).

Top Tips on Hot and Cold Water – Water efficiency is about conserving the precious resource of fresh clean water that New Zealand has, as well as conserving the energy to heat this water for use in church facilities. For this reason recommended actions point to lower water use fittings and improved insulation of hot water storage units. Operational procedures such as schedules for checking that appliances are set to ‘Eco’ modes, checking for leaks and checking hot water temperatures help to maintain high efficiency standards.

This sample graph shows what makes up this church’s electricity bill. Knowing your church’s Electricity consumption pattern for one year allows you to make more informed decisions when investing in capital such as new heating.
