Post-upgrade M&V
Buildings seldom achieve their optimum efficiency on day one. DeltaQ has developed the systems and processes to best able to monitor, and optimise energy usage post-completion of works. In addition to developing realistic energy targets for all sub-systems, we follow industry best practice guidelines (IPMVP) for accurate energy measurement at the gate meter and all sub-meters. We have two Certified Measurement and Verification Professionals (CMVP) staff members accredited in the application of IPMVP protocols.
In addition to energy measurement and reporting, we place a specific emphasis on ensuring that building controls are functioning optimally. In many cases this is the difference between building under-performance and achieving a 4.5 star NABERS or higher level of performance.
Our post-completion verification service includes:
-
Development of targets for the daily, weekly and monthly consumption of building sub-systems
-
Regular tracking & reporting of building & subsystem performance against NABERS/performance targets, including adjustment for variations in occupancy to provide real NABERS estimates
-
Regular (typically quarterly) detailed technical inspections of plant, controls and operation to identify energy efficiency related defects;
-
Tracking of defects and approval of defects resolution
Operations Review
Not all sites need to undergo a major upgrade in order to improve their energy performance. Since most buildings have a Building Management or Control System that controls the HVAC equipment and lighting, and the review of these systems provides a fantastic opportunity to deliver a “live rolling audit”. We call this service an “Ops Review”
An Ops Review is the ideal way to identify energy reduction opportunities in a simple and low-cost process that can lead to excellent cost effective savings.
In order to undertake an operational review, we visit your site and spend a day reviewing the operation and control of the plant via the BMS. We will take extensive observations and will supplement these with additional observations if a remote access to the BMS is available. We will analyse the data to identify performance issues and then develop a series of measures to implement. to the controls operation to improve energy efficiency.
We do not stop here! To ensure that these measures are actioned, DeltaQ’s team then attends site and works with your controls contractor to make sure approved control changes are implemented and savings are verified.
