Residential and office buildings are energy-hungry, and account for some 44% of all energy consumed, ahead of transportation (32%), industry (21%) and agriculture (3%). So improving their energy performance and controlling their consumption of energy more effectively are key challenges for the energy transition. Do you manage a real estate portfolio? Here are a few possibilities for improving the way you check the energy performance of your buildings and your consumption of natural gas.
ENGIE offers a range of building energy and environmental performance solutions that make it simple to analyze the energy consumption of a real estate portfolio as the basis for reducing energy bills.
Energy Performance Contracts are then put in place to improve and guarantee the energy efficiency of a single building or real estate portfolio benchmarked against a reference scenario.
This is the type of contract entered into between ENGIE-Axium and The Ohio State University in the USA, one of the country’s largest campus universities with 485 buildings. The University has outsourced the operation and optimization of all its energy generation and distribution infrastructures (steam, cooling, gas and electricity) to the ENGIE Group, together with a package of energy services underpinned by guaranteed to cut energy consumption by 25% over 10 years.
In multiple occupancy and social housing buildings, it is also relevant and appropriate to enable everyone living in the building to control their own consumption, especially where heating, hot water and cold water consumption is billed individually to each home. The ENGIE Vertuoz Habitat solution makes it possible to do precisely that. The natural gas fueled central heating plant is fitted with general meters to measure overall building consumption.
Each home then has its own individual meter to calculate occupant expenditure precisely, and thermostats to control the temperature. A remote meter reading unit uploads individual consumption figures as the basis for personalized billing.
Smart metering solutions enabling extremely accurate control of energy consumption are now really taking off. For example, smart meters make it possible to set a consumption threshold and receive a notification when that threshold is exceeded, and they can also be used to compare consumption with similar households to provide a clearer impression of relative consumption. All the data generated are saved so that consumption trends can be tracked over time. In France, all multiple occupancy buildings connected to the natural gas utility network will be fitted with Gazparsmart meters between now and 2022.
