Top view of a construction site where three skilled workers wearing safety helmets and high-visibility vests are discussing a construction plan. One person is holding a clipboard with a drawing, while a second is pointing to a plan or tablet and the third is standing next to them listening. Stacked formwork elements, bundled pipes and other building materials are scattered around the group; on the right, vertical and curved reinforcing steel bars protrude from the concrete. The scene depicts a construction site inspection with coordination of work steps, safety aspects and construction work in a shell construction environment.

Full‑cycle energy to future‑proof your development

Compliant metering, transparent billing and energy performancy built in from day one.

Handover is cleaner, operations smoother and assets more valuable over time.

Developers carry the risk long after the ribbon‑cutting.

You commit capital and reputation to every project, but the metering and energy setup can still undermine the outcome if it’s treated as an afterthought. Compliance gaps, disputed utility charges, “mystery” cooling bills and systems that are hard for operators to run all end up back at your door as complaints, delays and extra cost.

From concept to handover, we act as your full‑cycle energy partner.
We help your teams choose and specify the right BTU, water and electricity metering, connect everything to remote reading and billing, and ensure the building is ready for compliant, consumption‑based billing the moment it goes live. We work with you at the design and construction stage so metering, billing and connectivity are specified correctly upfront. All installed without disruption and ready for your buyer or OAM to use from the first day of operation.

After handover, we can stay on as the metering and billing partner for your buyer or operator, protecting your reputation with accurate bills, fewer disputes and clear energy data across the portfolio.

Digitalisation makes it easier.

Developments run smoother when metering, billing and data are connected from day one. Our digital tools turn utility infrastructure into a single, reliable system that cuts manual work, reduces disputes and gives operators and residents clear insight into what they use and pay.

A meeting is taking place in a modern, light-filled office with glass walls. In the foreground, one person is sitting at a table in front of an open laptop, with printouts and a pen next to them; another person is standing next to the table and appears to be moderating the discussion. A third person is sitting opposite, gesturing as if explaining a point. In the background, other people are working in a lounge area, separated by glass and furniture. The ceiling lighting and visible technical installations emphasise the contemporary character of the workspace and a collaborative, professional working atmosphere.

ESCO Solution & Services

Turn audit findings into guaranteed savings with full‑cycle ESCO delivery - from design and retrofit to independent Measurement & Verification that stands up in tenders, audits and disputes.

Close-up of several people at a shared workspace: hands typing on keyboards and operating computer mice on desktop PCs. One person is wearing a yellow knitted jumper and a bracelet; other arms can be seen blurred in the foreground. The scene conveys concentrated work in an office or training room.

Utility Billing

Move from manual processes to automatic billing: accurate reads, transparent invoices and stronger collections for every building in your portfolio, managed by one accountable partner.

A shot of a modern residential or office high-rise building from below. The light-coloured façade has a clear structure and is characterised by several staggered, widely projecting balconies. Glass railings and large window fronts reflect the daylight and provide insights into the interior. The balcony slabs form strong horizontal lines and create a dynamic, staggered silhouette. A bright sky can be seen in the background, making the contours of the building particularly clear. The image conveys contemporary architecture, urban living and high-quality building design.

Metering Technologies

Deploy MID‑approved BTU, water and electricity meters engineered for the region and integrated with remote reading and billing, so your buildings are ready for fair, compliant billing from day one.

A person is working at a desk in an office, pensively holding a pen in their hand while looking at a large monitor. Several windows with text-based content and coloured areas are open on the screen, suggesting analysis or development work. In the foreground, another screen is blurred, next to it are a keyboard and a coffee cup. The environment is warmly lit and looks like a focused workplace in a home office or study. The scene conveys focused work, digital information processing and a calm, professional atmosphere.

Remote Connectivity (MDMS)

Centralise data from every meter and building on one MDMS platform, with automated hourly reads, real‑time alerts and exports ready for billing and ESCO performance reporting.

Improve efficiency for the long term.

When your building’s biggest energy users are measured, upgraded and monitored together, you gain lower costs, clearer data and assets that are easier to operate year after year. Our services turn one‑off projects into lasting performance improvements for you and your residents.

A service technician is working on a flat roof next to a row of large air conditioning or ventilation units. He is wearing a hard hat and a reflective safety vest and is kneeling in front of the units. He is holding a tablet or clipboard in his left hand, while his right hand is touching one of the units, as if he were checking its condition. The housings of the outdoor units are lined up in a row and feature round fan covers. In the background, roof structures and a sloped surface with solar panels can be seen, above which is a bright sky. The scene conveys the maintenance and inspection of technical building equipment.

Replacement of low EER ACs

Planned replacement of low‑EER AC units with high‑efficiency systems, cutting energy use and operating costs while maintaining comfort across residential and commercial buildings.

A service technician wearing an orange safety vest and protective helmet stands in an industrial plant between pipes and machine components. He is holding a tablet in his hand and checking a plant unit at head height, as if he were checking measurements or documenting a maintenance step. In the background, cables, metal beams and other technical installations run along a narrow corridor, and the lighting is reminiscent of a production or technical area. The scene conveys inspection, maintenance and digital documentation of plant operation on site.

Energy Audit

Independent, ASHRAE‑standard audits that reveal where energy is wasted, what to fix first and what savings you can realistically achieve.

The picture shows a light-flooded part of an office space. Two men can be seen sitting at a desk directly in the foreground, stretching from left to right in the lower third of the picture. The man sitting on the left has short, dark brown and curly hair, a brown-red beard, wears round glasses with black frames and a black shirt. The man to his right has almost black short hair, a brownish beard and is wearing a black T-shirt. Both men are looking at the two monitors on the desk in front of them. Both men are looking at the carbon audit provided by ista on these monitors. To the left of the monitors on the desk is a black printer. To the right of the monitors is a telephone and next to it, on the right-hand edge, two letter trays are stacked. In the background you can see a wall consisting of large windows that stretches from the first left third of the picture to the right edge. In addition, the ceiling, which can be seen in the upper part of the picture, also consists of the same large windows. On the right-hand side of the picture, a dark brown, approximately waist-high room divider can be seen, which bends to the right once. Six plants can be seen on the room divider and behind it. To the left of the picture, directly next to the man on the left, is a wall consisting entirely of green plants.
