Many non-technical factors can impact on energy performance.[1. Bannister, P et al (2009) Low Energy High Rise Building Research Study – Final Research Survey Report. The Warren Centre]

The structures of leases, maintenance contracts and management responsibilities can support or hinder efforts to cut energy waste.

There are also a number of actions tenants can take to reduce their own energy use through energy efficient fitouts, benchmarking energy use, empowering staff and purchasing efficient office equipment. [1. Office of Environment and Heritage NSW (2012)  Energy Management Guide for Tenants  NABERS]

The Warren Centre has identified a series of practical means to improve the energy performance of large commercial buildings by implementing these non-technical measures listed below.

Energy efficiency measureNABERS energy impactMeasure summary (buildings perform best when):
Management1.3 starsManagement is at least partially in-sourced
Empowerment and accountability0.9 starsBuilding, asset and portfolio managers all feel able to affect efficiency
Disclosure0.5 starsNABERS performance is disclosed to tenants
Incentives and penalties0.4 starsService contracts provide efficiency penalties/incentive to maintenance contractors
Training and skills0.5 starsThere is an efficiency training program
 1.3 starsThe manager reports a higher level of energy efficiency knowledge
