The commercial case
The buyer is not purchasing a control device. They are purchasing a measurable result.
Bumi.Earth starts with the operational and financial outcome: lower electricity use, stable building conditions and evidence that technical and finance teams can evaluate together.
Lower energy cost
Reduce avoidable HVAC electricity consumption.
Measured savings
Compare performance against an agreed baseline.
Stable conditions
Optimise output without compromising required comfort.
Clear ROI
Connect energy performance to investment and payback decisions.
How DCD works
Demand-based control for the HVAC equipment you already operate.
DCD reads changing conditions, calculates the required response and regulates compatible variable-speed equipment continuously. The proprietary technology sits underneath a broader energy-optimisation service.

Estimate the opportunity
Turn the electricity bill into a first-pass business case.
The calculator separates the estimated HVAC portion of the bill and models an optimisation range. The free assessment then replaces assumptions with measured site data.
- Useful for early budgeting
- Relevant to owners, CFOs and facility teams
- Followed by a measured 14-day baseline

Best-fit buildings
Large HVAC loads. Long operating hours. High electricity spend.
The strongest opportunities are typically owner-operated buildings where the party approving the project also captures the energy savings.
Malls
Large cooling loads and long operating hours
Hotels
Demand shifts with occupancy and guest activity
Hospitals
Continuous operation and critical comfort needs
Universities
Multiple buildings, zones and schedules
Office towers
Variable occupancy across the working day
Factories
Process and comfort cooling at industrial scale
Data centres
High, measurable and continuous cooling demand

EECA 2024 readiness
Is your building ready for Malaysia’s energy-intensity requirements?
EECA 2024 and its regulations took effect on 1 January 2025. For buildings within scope, readiness is a sequence of clear responsibilities—not a single audit at the end.
01
Confirm scope
Review whether the building falls within the applicable criteria and identify the responsible stakeholders.
02
Display the label
Applicable buildings must apply for, renew and display an Energy Intensity Label.
03
Maintain performance
The minimum two-star performance requirement applies from the fifth year after the first label.
04
Audit and improve
If notified of non-compliance, appoint a Registered Energy Auditor and prepare the required report and improvement plan.
Where Bumi.Earth supports the work: measure HVAC performance, identify addressable waste and keep implemented improvements visible.
Bumi.Earth is not a regulator. This is general information and does not replace statutory guidance or advice from a Registered Energy Manager or Registered Energy Auditor.

About Bumi.Earth
Intelligent HVAC energy optimisation for commercial buildings.
BUMIDOTEARTH is a Malaysian building-technology company focused on practical energy performance. We combine engineering, connected technology and commercial thinking to make efficiency projects easier to prove and implement.
Our work begins with the way a building actually operates: measure the condition, identify the addressable load, build the business case and keep results visible after deployment.

Common questions
What owners, finance teams and engineers ask first.
A practical introduction to DCD, measurement and the assessment process.
No. DCD is designed as an intelligent control layer for compatible variable-speed equipment. Bumi.Earth assesses the existing plant, controls and measurement points before recommending a deployment approach.
