Floor area of existing buildings individually assessed for energy performance:
210,887 Square meters

Narrative outlining how building-level energy performance is assessed and how the results are used to improve performance:
TU Dublin has built an inventory of its electrical, gas, and water Public energy meters and hwo those are connected to buildings. The building inventory details the floor area of each building. The energy bills have then be analysed to associate energy consumption and costs of each public energy meter and distribute those across connected buildings according to the floor area of each building. Energy conversion are then convertd to tonnes of dioxide emission equivalent using AASHE STARS and international kWh to tCO2e conversion factors.
In addition, the Sustainable Energy Authority of Ireland (SEAI) does a similar exercise by interrogating energy providers on consumption asociated to our reported public energy meter. Additional information about our building inventories are reported to the SEAI Monitoring and Report platform which is then used to generate the SEAI Annual Report.
Finally TU Dublin compare its own analysis with SEAI analysis. Data from 2022 and onwards are matching.
The results informed the decarbonisation strategy and action plans defined in the Climate Action Roadmap.
Improvement on the actual energy consumption, cost, and associated tCO2e are ongoing with the installation of additional electrical, gas, district heating, and water meter for each building, together with the upgrade of our Building Managament Systems, the data collection and processing onto an Energy Management System, and the creation of digital twins - see the "Towards a Sustainable University Campus" project for more information (Ref 1).

Narrative outlining how building-level water performance is assessed and how the results are used to improve performance:

Water consumption is mostly measured at a campus and building area level by analysing our water bills. Water consumptions are monotired on a monthly and annual basis to identify the imact of water saving measures or the added consumption for the creation of new buildings and services.
Water consumption at the building level is currently done only in one building, the Greenway Hub that is a research building of 4,270 m2. Consumption is tracked from sensors connected to teh building management system.


Floor area of existing buildings third party certified to a green building standard:
9,555 Square meters

List of the institution’s existing buildings and their green building certifications:

Existing buildings built from 2019 to 2024 with a Building Energy Rating (BER) A2 or better, and thereby considered NZEB, are listed below  - TOTAL BELOW 9,555 M2:
Tallagh North, 2024, NZEB (BER A2+), 5,200m2
Aras Geal, 2024, NZEB (BER A2+), 4,040m2
Printmaking Workshop, 2021, NZEB (BER A2) 315m2
