    Hi,

    Does anyone know if the standards re. energy use for educational buildings differ from those for domestic buildings?

    I thought maybe for example, a secondary school might have a higher electricity or even DHW "allowance" than a domestic building, due to the labs and sports activities.

    I've read that a domestic building should have 60 kWh /m2a total energy use (https://passiv.de/en/02_informations/02_passive-house-requirements/02_passive-house-requirements.htm)

    I'm assuming the space heating requirement would be the same as domestic

    Posted By: minisaurusI've read that a domestic building should have 60 kWh /m2a total energy use (https://passiv.de/en/02_informations/02_passive-house-requirements/02_passive-house-requirements.htm)

    What that actually says is that "the total energy to be used for all domestic applications (heating, hot water and domestic electricity) must not exceed 60 kWh per square meter". So it's talking about specific uses of electricity, not total energy use.

    Hi MS, in the UK there are building standards for non domestic buildings, which are different from standards for houses, and different in eg Scotland and England where climate is different.

    Schools are only occupied for ~15% of the time. They need to be warm before the kids arrive in the morning, but not overheat when all the children come in. They need lots of lighting and ventilation during the short time when they are occupied. They are bigger buildings than houses (less surface area) with more people per m2, and often have more windows and doors.

    So overall their energy consumption per m2 is not comparable with houses.

    I've not been involved in a certified school, only residential, but from what I can tell the requirements are fairly similar to the domestic targets.

    This article gives a fairly good breakdown:

    There's more here:

    https://passipedia.org/planning/non-residential_passive_house_buildings/passive_house_schools/how_go_about_it


    Particularly worth noting the following passage:

    "An important boundary condition is the intermittent use with temporarily extremely high internal loads. The temporal average value of the internal loads with 2.8 W/m² on average is not much more than the values for residential use. Setback phases play an important role in school buildings. A tool is available for determining the expected effective temperature reduction"

    So the use patterns of the classrooms are a key difference compared to domestic.

    Great links, thank you Doubting Thomas; those links led on to interesting case studies from several places - Frankfurt, somewhere in Austria.

    You're right, the heating requirement is the same, or similar - around 15 kWh/m2/year
