Energy monitoring and verification in BREEAM and LEED certifications

Monitoring energy consumption is an important aspect of energy management. Regular monitoring and evaluation of consumption helps to detect wastage, find potential savings or detect faults early to detect energy leaks. The importance and relevance of energy monitoring is also reflected in the BREEAM and LEED certification schemes. Implementing energy monitoring means gaining a higher score in these certification systems.
Currently, not only monitoring of the main meters but also of the sub-meters is necessary to achieve a high rating. It is essential that the secondary metering is appropriately selected with respect to the building and the nature of the operation.

What you get: An energy efficient and better rated building

BREEAM NEW CONSTRUCTION

ENE 02 Energy Monitoring

This credit deals with the introduction of sub-metering of individual energies. The use of a data acquisition and processing system is also a prerequisite. Depending on the type of building, either 1 or up to 2 credits can be earned.

WAT 02 Water Monitoring

A criterion for receiving credit in this area is monitoring water consumption, which will help to better detect potential waste and identify potential water saving opportunities. By meeting the requirements, 1 credit can be earned.

WAT 03 Water Leak Detection

In this area, attention is paid to reducing the negative impacts of water leakage. By monitoring water consumption, it is possible to detect any defects and faults in the distribution system or in end fittings and appliances in good time. The introduction of monitoring, when combined with other measures, can provide a gain of up to 1 credit.

BREEAM IN USE

ENE 68 Energy Management System

This area deals with energy management in the building. It is possible to get 1 credit for implementing energy monitoring alone. However, through the use of monitoring, it is also possible to earn additional credits together with a combination of other measures related to energy savings and energy management - for example 1 credit for regular monitoring and control of the set energy savings targets.

ENE 69 Trends in Energy Performance Data

This area deals with the regular assessment of energy consumption and the monitoring of consumption trends according to different periods. The introduction of energy monitoring allows easy analysis of energy consumption and thus simplifies the evaluation. Up to 2 credits can be earned if the evaluation is carried out regularly at least 2 times a year.

LEED - NEW CONSTRUCTION

EA Credit 5 – Measurement and Verification

Enhanced Commisioning (1 bod)
The main focus of this area is to ensure that the design and operation of the building meets the design requirements in terms of energy, indoor environmental quality and durability. The introduction of energy monitoring allows energy and water consumption to be monitored and also helps to detect various faults or leaks. The implementation of energy monitoring, together with the fulfilment of other requirements, can contribute to the achievement of 1 point in this area.

Advanced Energy Metering (1 bod)The main purpose of introducing energy monitoring is to support energy management and to easily identify potential energy savings. It is also a prerequisite to introduce secondary metering for areas that consume more than 10% of the measured energy. The introduction of energy monitoring meeting the criteria may be awarded 1 point.

LEED O+M: EXISTING BUILDINGS

Water Metering (Up to 2 credits)Earning points for this credit is contingent on the installation and regular reading and monitoring of water consumption in the building. Water meter readings must be taken at least weekly and the data collected will be used to regularly analyze trends in water consumption in the various subsystems of the facility.

Advanced Energy Metering (Up to 2 credits)This credit is concerned with measuring the energy consumption of the building and finding any potential savings. The data collected is used to monitor consumption trends and identify potential savings. The acquisition of these points is also conditional on the setting of an automatic alert if the consumptions are more than 5% higher than the predicted value. Furthermore, a comparison must be made each month with the consumption for the previous months and also for the same period in the previous year.
