Plan of St Andrews School Chedworth

A Net Zero Carbon School - St Andrews Primary, Chedworth

An electric vehicle charger has been installed to enable the staff to choose to use EVs and charge while at work.

Electric Vehicle Charging

Many of our classrooms have had insulated suspended ceilings fitted recently as part of our conversion to a net zero carbon school. These help to keep the heat in and also reduce the noise reverberation in the classrooms to create a quieter teaching and learning space.

Insulated ceilings

All of the schools hot water needs are met by local electric point of use water heaters

Electric point of use water heating

As part of being a net zero carbon school all of our windows are now fully double glazed to keep the heat in and create a comfortable and quieter free teaching and learning environment

Double glazed windows

Each classroom (and the staffroom) has an indoor air quality sensor constantly measuring the CO2, VOC, Radon, Humidity and Temperature in the rooms and altering the teachers and the head when the air quality falls below the best standards so they can open the windows.

Indoor Air Quality Sensor

All of our display boards are hessian backed provide a calmer internal environment and can be re-used avoiding larger amounts of paper waste being generated.

Hessian Back Boards

As part of being a net zero carbon school all of our lighting is the lowest energy LED units which also provide the best quality light output available, free from flicker, to provide the best possible lighting for teaching and learning.

30 Solar panels provide much of the schools electrical needs

Four 14kW Air Source Heat Pumps provide all of the schools heating requirements. (There is no back up or secondary boiler). The hot water is provided from point of use electrical water heaters.

The PV panels are wired back through two invertors

Solar PV Invertors

A 5kW PV battery retains excess PV generation through the day and weekends and uses this to power the schools residual systems over night.

PV Battery

Separate pump sets for each heat pump allow them to be staged to meet demand

ASHP Pumps and Meters

Seperate control boxes for each ASHP and master controller. Allows for overall timing and holidays to be set. Generally ASHPs are run from 4am to 5pm Monday to Friday. The early start allows for warm up. 24/7 operation has been found not to be required.

ASHP Controls

All of our old cavity walls have been insulated to avoid heat loss in our net zero carbon school and help to create warm and comfortable teaching and learning environments inside.

Insulated Walls

We have dedicated an area of the school for wildlife and manage this space top encourage the growth of wild-flowers
