Student Accommodation Energy Management — Intelligent PBSA Energy Control
Totem reduces energy consumption in purpose-built student accommodation by up to 75% through room-level control, automated scheduling, and wireless retrofit installation. No rewiring, no disruption to residents, savings from day one.
The PBSA energy problem
Heating accounts for up to 70% of total PBSA running costs. All-inclusive rent means students have no financial incentive to manage energy. Electric heaters, panel heaters, and towel rails run continuously in empty rooms — during lectures, weekends, and vacation periods. Traditional building management systems operate at zone or building level and cannot address room-level waste. Totem was designed for exactly this problem in existing buildings without renovation.
The system — two components
Totem Connect: central hub connecting to building internet and mains power, managing up to 35 Totem Control units via wireless mesh. Installs in riser cupboard. Multiple hubs for larger buildings. All feeding one centralised dashboard.
Totem Control: room-level unit installing inside or behind existing wall sockets ahead of electric heaters, towel rails, or any device above 500 watts. Full room commissioning approximately 15 minutes. No drilling, no rewiring, no damage to building fabric. Qualified electrician handles installation — no specialist engineers required.
Seven ways Totem improves PBSA operations
Improve Net Operating Income: energy savings flow directly to NOI, improving operating margins and asset valuations. Real-time monitoring: live energy consumption per device and room across the portfolio. Individual room control: device-level switching, scheduling, and monitoring. Automated scheduling: aligned to term dates and timetables. Inter-term setback: heating drops to frost-protection during vacations automatically. Energy data analytics: room-level consumption data for EPC assessments and ESG reporting. Portfolio scalability: one dashboard for all sites, no ceiling on scale. Unauthorised heater detection: high room temperature combined with low controlled-device kWh flags third-party devices — a fire risk and insurance compliance issue surfaced automatically.
Installation
Riser cupboard access for hub. Each room approximately 15 minutes — remove socket faceplate, install Totem Control unit, make good, fit push-button and temperature sensor. No rewiring, no structural work. Full floor commissioned in a single day. No disruption to residents. Savings begin immediately on commissioning.
EPC and regulatory compliance
UK Minimum Energy Efficiency Standards require EPC C for new and renewed tenancies from 2028 and all existing tenancies by 1 October 2030. New Home Energy Model (HEM) launches H2 2027 with four metrics: Fabric Performance, Heating System, Smart Readiness, and Energy Cost. Electrically-heated PBSA has viable compliance routes on both the Heating System and Smart Readiness metrics. Totem's room-level data supports EPC assessments and GRESB energy reporting.

The PBSA energy problem
Heating is your largest controllable cost —
and most of it is wasted
In electrically-heated PBSA, heating accounts for as much as 70% of a building's total running costs. Electric heaters, panel heaters, and towel rails run continuously in empty rooms — during lectures, weekends, vacation periods, and overnight — consuming energy that operators are paying for with no benefit to residents.
Traditional building management systems are expensive, invasive to retrofit, and operate at the building level rather than the room level. Operators have had no practical way to manage energy device by device, room by room, without significant capital investment in new infrastructure.
Totem was designed to solve exactly this problem — for existing PBSA buildings, without renovation.

Why PBSA operators choose Totem
Seven ways Totem improves your operation
💷
Improve Net Operating Income
Energy savings flow directly to NOI. Reducing consumption by up to 75% materially improves operating margins and asset valuations.
📡
Real-time monitoring
Live energy consumption for every device and room across your entire portfolio from one dashboard. Identify high consumers and act immediately.
🎛️
Individual room control
Control energy at device level, not just building level. Power down heaters in unoccupied rooms and restore comfort before residents return.
🗓️
Automated scheduling
Custom schedules aligned to term dates and lecture timetables. Devices power down automatically during unoccupied periods without manual intervention.
📊
Energy data analytics
Device-level consumption data supports EPC assessments, GRESB reporting, and ESG due diligence. Verifiable, continuous, room-level.
🏢
Portfolio scalability
From a single building to a multi-site portfolio — all managed from one dashboard. No new cabling infrastructure required to expand.
🔍
Unauthorised heater detection
A room showing high temperature but very low kWh from the controlled device is a strong indicator of a third-party heater. Totem surfaces this automatically — giving operators visibility of a fire risk and insurance compliance issue that would otherwise go undetected.
Retrofit installation
Designed for existing buildings —
no renovations required
Totem was built for retrofit installation in existing PBSA buildings. No new wiring, no structural alterations, no replacement of existing heating equipment. A qualified electrician can commission a full floor in a single day.
Savings begin immediately on commissioning — there is no warm-up period, no calibration phase, and no learning period required.
Step 1
Riser cupboard — Totem Connect
Hub installs in riser with mains power and internet connection. Wired or Wi-Fi. Takes under an hour.
Step 2
Each room — ~15 minutes
Remove socket faceplate, install Totem Control unit, make good, fit push-button and temperature sensor to agreed location.

Common questions
Frequently asked
Can Totem be retrofitted into existing student housing without major renovations?
Yes — and this is where Totem is fundamentally different from traditional BMS. Installation requires riser cupboard access for the hub and approximately 15 minutes per room. There is no new wiring between rooms, no structural alterations, and no replacement of existing heating equipment. The system communicates wirelessly via a self-healing mesh network.
What access is needed to install Totem in a PBSA building?
Two types: riser cupboard or plant room access for the Totem Connect hub (must have a mains power point available), and each individual room for approximately 15 minutes. A qualified electrician removes the existing socket faceplate, installs the Totem Control unit, makes good, then fits a push-button and temperature sensor to a location agreed with the operator.
What are the benefits of real-time energy monitoring in student accommodation?
Real-time monitoring delivers benefits across cost, operations, sustainability, and compliance. Heating accounts for up to 70% of PBSA running costs — monitoring identifies and eliminates waste from unoccupied rooms, failed equipment, and inefficient scheduling. Key benefits: energy reduction up to 75%, accurate data for EPC compliance and ESG reporting, automated fault detection, configurable occupancy schedules, and per-device analytics.
Does Totem affect resident comfort?
No. Schedules are configured to restore heating before residents return — rooms are warm when needed. The resident boost button provides on-demand heat at any time. At Bargate House, there have been zero complaints about comfort since installation.
Can Totem detect unauthorised electric heaters?
Yes. A room showing high temperature but very low kWh from the controlled device is a strong indicator of a third-party heater. Totem surfaces this automatically — giving operators visibility of a fire risk and insurance compliance issue that traditional BMS systems cannot detect at room level.
How does Totem support EPC compliance?
Totem's room-level consumption data directly supports EPC assessments. Under the new Home Energy Model (HEM) launching H2 2027, electrically-heated PBSA has viable compliance routes on both the Heating System and Smart Readiness metrics. EPC C is required for new and renewed tenancies from 2028, and all existing tenancies by October 2030.
