# J1V5 Air-conditioning Setpoints

## **What are the specified heating thermostat settings for conditioned zones in climate zones 2 to 8 according to the requirements?**

The heating thermostat setting is 20°C for all conditioned zones from 6:00 am to 12:00 am (daytime), and 18°C at all other times (night-time).

## **In which climate zones is the cooling thermostat setting 27°C for daytime conditioned zones from 6:00 am to 11:00 pm?**

The cooling thermostat setting of 27°C applies to daytime conditioned zones in climate zones 1, 2, and 3.

## **What is the cooling thermostat setting mandated for all climate zones?**

These settings are specified for the daytime and night-time periods as required by the compliance standards for air-conditioning services in different climate zones. The nighttime cooling thermostat setting is a constant 24°C for all night-time conditioned zones across all climate zones.

| Climate Zone              | Daytime Cooling Thermostat Setting (6:00 am to 11:00 pm) | Night-time Cooling Thermostat Setting |
| ------------------------- | -------------------------------------------------------- | ------------------------------------- |
| Climate zones 1, 2, and 3 | 27°C                                                     | 24°C                                  |
| Climate zone 4            | 26°C                                                     | 24°C                                  |
| Climate zone 5            | 25°C                                                     | 24°C                                  |
| Climate zones 6 and 7     | 24°C                                                     | 24°C                                  |
| Climate zone 8            | 23°C                                                     | 24°C                                  |

## **What are the requirements for heating thermostat settings during nighttime in climate zones 2 to 8?**

 The heating thermostat setting during nighttime is mandated to be 18°C for all conditioned zones in climate zones 2 to 8.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.betterbuilding.io/user-guide/workflows/energy-efficiency/j1v5-verification-using-a-reference-building-for-a-class-2-sole-occupancy-unit/j1v5-air-conditioning-setpoints.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
