Energy efficiency starting with measurement.

S4 reduces the energy consumption of buildings and sites by first measuring where, when and on what energy is spent. With that data we prioritize measures (LED lighting with control, automation, load management) by payback, and measure again to verify the savings.

Measure, prioritize by payback and measure again against the baseline.

Who it is for

Finance manager

Measures justified with data and executable in phases.

Facility manager

Know where the energy goes and act on it.

Sustainability lead

Measured data for reports and certifications.

You cannot reduce what you do not measure.

The energy bill arrives as a single number. Without metering by circuit or area, every measure is a bet: luminaires get replaced where they did not weigh much, or a machine that draws power all night goes unnoticed.

You need it if you recognize any of these signs:

Only the total consumption on the bill is known.
Night or weekend consumption is high with no explanation.
Changes were made without checking the savings afterwards.
There are sustainability or certification targets with no baseline data.

How the system is built.

Meters integrate with the building platform through open protocols such as Modbus or BACnet, so energy can be seen alongside lighting and HVAC and measures can be automated.

What is included and what is not.

Included in the service

Review of bills and of the installation
Metering by area or circuit where needed
Baseline and analysis of consumption profiles
Measures plan prioritized by payback and impact
Implementation of lighting, control and automation measures
Measurement and verification of the savings

Out of scope

Tariff negotiation with the energy supplier
Tax advice on incentives
Building envelope or structural works

Anything out of scope is coordinated with the right party or quoted separately, and is always stated in writing before we start.

How we do it, step by step.

Assessment

Bill analysis, site walk-through and metering where needed to learn actual consumption.

Reference regulations and standards.

These are the usual references for this type of system. The technical report of each project identifies which ones apply, depending on the use, size and location of the installation.

Regulatory reference, indicative

ISO 50001: Energy management systems; a framework for continually improving energy performance.
IPMVP: International protocol for measuring and verifying savings.
Law 1715 of 2014: Colombian law that regulates the integration of non-conventional energy sources and efficient energy management, with tax incentives that your adviser must confirm.
RETILAP: For measures that affect lighting.
RETIE: Colombian technical regulation for electrical installations: governs the service connections and circuits that power the equipment.

What people ask us most.

Where do you start?

By measuring. Without data on where and when energy is used, you cannot prioritize or verify the savings.

How are the savings verified?

By comparing later consumption with the baseline measured beforehand, adjusted for changes in use or occupancy. That is why measuring first matters.

Can the measures be financed in phases?

Yes. The plan is split into phases by priority, so that the first measures help justify the next ones.

Does it include solar energy?

If the assessment supports it, we evaluate self-generation as one more measure in the plan, compared with the others by payback.

Are there incentives for these investments?

Law 1715 of 2014 provides incentives for efficient energy management and renewables. Their application depends on each case and must be confirmed by your tax adviser.
