Crèches

Envirometer for crèches

In a project carried out by Rotterdam municipal authority, crèches were benchmarked using the Envirometer, with a a total of fourteen creches providing their Envirometer data over 2001. These data were used to compute an average Envirometer and scores on the individual indicators. The results of this benchmarking exercise are reported below.

Envirometer

On the right, the average Envirometer of the 15 crèches responding. In this case 'fuel' refers to gas or district heating. For the average crèche, the shares of the environmental themes are as follows:

24% electricity
32% heating
44% commercial waste
1% water and sewage

Transport (commuting and business travel) have not been included, because these data were filled in by only a few of the respondents.

Indicator scores

The table below shows the indicator scores that emerged from the benchmarking of crèches. We report the average and best results. All the scores are on an annual basis.

Indicator scores for crèches, 2001 (n=14)
Environmerntal theme	Indicator score	Unit	Average	Best
Electricity	electricity / floor space	kWh/m²	58	32
	electricity / child capacity	kWh/child capacity	493	233

Heating	gas / building volume	m³gas-eq./m³	7.6	3.0
	gas / child capacity	m³gas-eq./ child capacity	194	106

Water	water / child capacity	m³/child capacity	12.5	6.6

Waste	waste volume (total) / child capacity	liter/child capacity	973	587
	waste weight (total) / child capacity	kg/child capacity	146	88
	fraction of waste separated	%	6	46

Costs	energy costs / child capacity	€/child capacity	100	66
	total environmental costs / child capacity	€/child capacity	170	115

"Child capacity" was calculated as: (number of children*occupancy) + (capacity for after-school and/or similar non-school care*0.5).
