Sectors — Schools & Universities

Your campus is two different institutions, and the bill only knows one of them

No other sector runs a calendar like this one, and no monthly total will ever tell a bursar which of the two states a payment belongs to.

For part of the year

The estate is full. Lecture theatres in use, laboratories running, halls of residence occupied, and consumption largely doing what it was built to do.

For the rest of it

Most of the campus is empty. If the bill does not fall substantially between the two, the institution is paying for something it is not using.

The same estate, twice a year

Metering makes the two states comparable. The gap between them is where the questions are.

In term

The campus does what it was built to do, and consumption is largely legitimate. The useful question here is not how much, but where — which faculty, which building, which hall.

  • Occupancy drives the loadLighting, fans and air conditioning follow the timetable, and laboratories and workshops draw hard in blocks.
  • Residences peak outside teaching hoursHalls consume in the evening and early morning — hot water, cooking, devices — the inverse of the teaching estate.
  • Cost has a departmentMetered by building, consumption can be attributed to a faculty, a hall or a service, which is what makes a reduction target something a person can own.

In vacation

Almost nobody is on site, so almost everything the meters record is either necessary standing load or waste. This is the most revealing period in the academic year and the least examined.

  • What should still be runningSecurity and external lighting, servers, water pumping, refrigeration in catering and laboratories, a limited residential presence.
  • What usually still isAir conditioning in closed offices, lighting in empty blocks, laboratory equipment left energised, water heating for residences with nobody in them.
  • What the difference is worthMultiplied across the weeks a campus stands empty each year, the gap between those two lists is usually the largest single saving available to the institution.

The empty-campus baseline

Measure what the estate draws when nobody is there. Agree what it ought to draw. The difference between those two numbers is standing waste, and unlike most energy savings it can be pursued without asking a single student or lecturer to change anything.

Once the baseline exists it also becomes the institution’s control. Every subsequent vacation is measured against it, so a building that was shut down properly last year and not this year shows up immediately — before the bill arrives, and while there is still vacation left to correct it.

It is also the number that decides a solar investment. A campus consumes while it teaches, in daylight, which is the best possible match for an array — but a system sized on term-time consumption will spend several weeks a year generating into a near-empty estate. Both states have to be measured before the capacity is fixed, which is what solar project development starts from here. Both states are what term-by-term energy reporting sets side by side, which is the comparison a bursar is actually asked for.

What gets metered on a campus

Campuses are metered by building and by service, because that is how they are managed and how their budgets are held. A school with three blocks and a university with forty buildings are the same problem at different scale.

Meter tier follows the current rating of the circuit; every three-phase meter takes three current sensors. Deployment is normally phased, starting with the highest consumers.

Where an institution needs a one-off study rather than continuous monitoring — for a capital submission, a donor requirement or a sustainability report — an energy audit is scoped to the estate instead.

Teaching estate

  • Lecture theatres and classroom blocks
  • Laboratories and workshops
  • Library and study spaces
  • ICT suites and server rooms

Residential estate

  • Halls of residence
  • Student kitchens and common rooms
  • Water heating and hot-water storage
  • Warden and staff accommodation

Estate services

  • Water pumping and boreholes
  • Catering and dining halls
  • Sports facilities and floodlighting
  • External, perimeter and security lighting

Halls of residence are their own problem

Residences are the one part of a campus where the people consuming the electricity are not the people paying for it. That is not a discipline problem to be solved by metering; it is a design problem that metering makes visible.

With each hall metered separately, an institution can see what residential occupancy actually costs, set the accommodation charge against evidence, compare halls, and identify the ones where water heating or an ageing installation is doing more damage than student behaviour ever could.

One thing only a campus can do

A live estate is also a teaching resource

For an institution teaching engineering, environmental science, economics or estates management, a metered campus is a real data set generated on site rather than a textbook example from somewhere else.

Where an institution wants it, platform access can be extended to academic staff for teaching and student project work — and the same data underpins the sustainability reporting many universities now publish.

Establish the baseline before the next vacation

The measurement only means something if it exists on both sides of the term date, which makes this the one sector where the timing of the assessment matters as much as the scope of it.

  1. While the campus is still full

    An assessment maps the estate and proposes which buildings, halls and services to meter first. Installation is scheduled with your estates team while the boards are accessible and the site is staffed.

  2. Once it empties

    The meters read a campus with almost nobody on it. That is the figure the institution has never had, and the one every subsequent vacation is measured against.
