CONCLUSION
The Remarkable Benefits of Installing Air Conditioning in a Small Rural School The installation of air conditioning in this small school in Devon has resulted in staggering savings on heating costs.
The school is now receiving an annual saving of over £9k, which is a very substantial percentage of their budget. Furthermore, the school has reduced its CO2 emissions by over 5 tonnes per year.
Their investment has been recouped in less than 18 months, and over the life of the units (estimated at 15 years, but probably more), the school can expect to save over £130000.
This huge amount of funding can now be used by the school to improve the quality of education for generations of students.
