Getting the best out of a property portfolio includes finding ways to effectively reduce operating costs and energy use, while maintaining agreed service levels.
Establish a base of information for each site within the agency’s property portfolio, defining:
Use this information, along with data related to the cost of maintaining and operating facilities, to build an overview of where cost efficiencies could be improved.
You can use the Government Property Portal to log and track corrective and preventative maintenance requirements.
We strongly recommend using any All-of-Government or Common Capability contracts that are available for the services required. These have been set up to ensure cost savings across government.

Ensure all facilities management contractors are appropriately performance managed against agreed key performance indicators.
We recommend using a common methodology for scoring essential areas, including:
Cabinet expects agencies to adopt cost effective options for managing and reducing their energy consumption.
To do this, you'll need a clear understanding of the current energy use at each tenancy.
For each tenancy site your agency uses:
Electricity contract – New Zealand Government Procurement
Reticulated gas contract – New Zealand Government Procurement
Ensure site metering is correct. Metering should reflect the size and expected tenancy of a site, with the flexibility for separate future floor-by-floor tenancies.
For a standalone tenancy, the electricity should all be powered through a single meter. The one meter should be a time-of-use meter, that can analyse:
For multi-tenanted buildings there should be:
Where there are multiple tenancies per floor or the tenancy has its own HVAC units, further sub-metering may be needed. NABERSNZ (The National Australian Built Environment Rating System as adapted for New Zealand) has more guidance on what metering you might need for your situation.

Using the data you've gathered, develop a plan of actions to take to reduce energy use.
Assign responsibility for the plan and reporting to an appropriate member of staff. If multiple sites are involved, energy usage accountability should be managed centrally.
Communicate the situation to all staff – outline the agreed strategies and how staff will need to use the space, expected outcomes and how their efforts will contribute to these outcomes.
Provide an annual report back to senior managers updating them on progress across the portfolio. This report should highlight individual performance across all sites.
