How We Cut Allianz
Malaysia's Energy Bill
by 70%

The brief: cut operating costs across two prime KL office towers without disrupting a working headquarters.


We audited 13 office floors. Within months, consumption dropped 16,400 kWh a month and the full investment paid back in under 18 months.


This became the proof of concept for our Shared Savings model.

Models Built Around
Your Cashflow

01

Consulting Services

Full assessment across M&E, operations, and waste. Clear recommendations with quantified outcomes.

02

Shared Savings

Defined investment, savings, and payback per measure. Once results land, we share a percentage for an agreed period.

03

Co-Investing

On select projects, we co-invest directly. You get the efficiency gains immediately; we recover through a share of savings over an agreed period.

Best fit when
Savings are predictable and the baseline is measurable.
What you get
Implementation without capital outlay, and a partner invested in the result.
