There are many opportunities to reduce energy consumption in existing commercial buildings. With some minor adjustments and changes it’s often possible to reduce energy bills by up to 15%. Further reductions can be made through capital improvements involving upgrading walls, windows, roof, HVAC equipment, lighting and domestic hot water systems. This presentation will review the process of evaluating the potential of energy saving opportunities and look at how they are typically implemented in buildings. Case studies of example projects will be presented. We will also highlight grants and incentives that are available to help offset the costs of these upgrades. And we will provide an overview on how retro-commissioning ties into LEED-EB and an explanation of the related pre-requisites and credits.

The grant provides support of up to €1,000,000 per project. This goes to help businesses embed energy efficient design in their investment projects. It is open to private businesses and public sector organisations who are planning an investment project.
It is relevant to:
Brand new buildings and facilities
Upgrades or re-purposing of existing buildings and facilities
Manufacturing processes
This session will give an overview of the SEAI EXEED programme. It will provide case study examples from organisations. These organisation have all implemented these Energy Efficient Design principles within project investments.
A printed circuit board (PCB) is a fundamental component in modern electronics that serves as a platform for assembling and connecting electronic components. It provides a solid foundation for the interconnection of various electronic elements, including integrated circuits (ICs), resistors, capacitors, and other passive and active components.
The construction of a PCB typically involves a thin board made of non-conductive material, often fiberglass reinforced with epoxy resin or other laminates. The surface of the board is coated with a layer of copper, which serves as the conductive material for the electrical pathways.
PCB design involves a meticulous layout of conductive traces, which form the pathways for electrical signals to flow between components. These traces are usually etched onto the copper layer through a process of chemical etching or mechanical milling. The layout of the traces is determined by the circuit schematic, aiming to minimize signal interference, optimize signal integrity, and ensure efficient electrical connectivity.
In addition to the conductive traces, a PCB features various other elements. These include pads and vias. Pads are small areas of exposed copper where electronic components are soldered onto the board. Vias are holes drilled through the board that connect different layers of the PCB, facilitating the routing of traces between them.
PCBs can have multiple layers, ranging from single-sided boards with components mounted on one side, to double-sided and multi-layer boards, which have components mounted on both sides and multiple layers of conductive traces sandwiched between insulating layers.
The manufacturing process for PCBs involves several steps, including design and layout, fabrication of the board itself, application of the copper layer, etching or milling of the traces, drilling of holes for components and vias, and finally, assembly of components onto the board through soldering or other methods.
PCBs are essential in a wide range of electronic devices, from simple consumer electronics like calculators and remote controls to complex systems like computers, smartphones, and medical equipment. Their compact design, reliability, and scalability make them indispensable in the world of modern electronics, enabling the creation of increasingly sophisticated and efficient electronic devices.

NUMERICAL SIMULATIONS OF HEAT AND MASS TRANSFER IN CONDENSING HEAT EXCHANGERS...ssuser7dcef0
Power plants release a large amount of water vapor into the
atmosphere through the stack. The flue gas can be a potential
source for obtaining much needed cooling water for a power
plant. If a power plant could recover and reuse a portion of this
moisture, it could reduce its total cooling water intake
requirement. One of the most practical way to recover water
from flue gas is to use a condensing heat exchanger. The power
plant could also recover latent heat due to condensation as well
as sensible heat due to lowering the flue gas exit temperature.
Additionally, harmful acids released from the stack can be
reduced in a condensing heat exchanger by acid condensation. reduced in a condensing heat exchanger by acid condensation.
Condensation of vapors in flue gas is a complicated
phenomenon since heat and mass transfer of water vapor and
various acids simultaneously occur in the presence of noncondensable
gases such as nitrogen and oxygen. Design of a
condenser depends on the knowledge and understanding of the
heat and mass transfer processes. A computer program for
numerical simulations of water (H2O) and sulfuric acid (H2SO4)
condensation in a flue gas condensing heat exchanger was
developed using MATLAB. Governing equations based on
mass and energy balances for the system were derived to
predict variables such as flue gas exit temperature, cooling
water outlet temperature, mole fraction and condensation rates
of water and sulfuric acid vapors. The equations were solved
using an iterative solution technique with calculations of heat
and mass transfer coefficients and physical properties.
Using recycled concrete aggregates (RCA) for pavements is crucial to achieving sustainability. Implementing RCA for new pavement can minimize carbon footprint, conserve natural resources, reduce harmful emissions, and lower life cycle costs. Compared to natural aggregate (NA), RCA pavement has fewer comprehensive studies and sustainability assessments.

Hierarchical Digital Twin of a Naval Power SystemKerry Sado
A hierarchical digital twin of a Naval DC power system has been developed and experimentally verified. Similar to other state-of-the-art digital twins, this technology creates a digital replica of the physical system executed in real-time or faster, which can modify hardware controls. However, its advantage stems from distributing computational efforts by utilizing a hierarchical structure composed of lower-level digital twin blocks and a higher-level system digital twin. Each digital twin block is associated with a physical subsystem of the hardware and communicates with a singular system digital twin, which creates a system-level response. By extracting information from each level of the hierarchy, power system controls of the hardware were reconfigured autonomously. This hierarchical digital twin development offers several advantages over other digital twins, particularly in the field of naval power systems. The hierarchical structure allows for greater computational efficiency and scalability while the ability to autonomously reconfigure hardware controls offers increased flexibility and responsiveness. The hierarchical decomposition and models utilized were well aligned with the physical twin, as indicated by the maximum deviations between the developed digital twin hierarchy and the hardware.

• Initially developed in Denmark > 10 years
ago
• Intended as a sanity check on the project
design from a energy and water
consumption perspective
• Required for ISO 50001
• New build/upgrade is opportunity for open
mind to deliver step changes:
• Change the Process
• Challenge Peak Calculations / Future
Expansion allowances
• Right size Process or Utilities
• Allows optimum measurement and
metering strategy to be employed
• Usually helps to reduce Capex also
• “Savings” from Poor Design and Cheap
Equipment usually cost significantly more
over lifecycle of equipment
7. Energy Efficient Design, how FDT
implement EXEED
In practice the ESR is the hub around
which EED is built and how it is
integrated into the conventional project
workstreams – via change control
8. Project Execution Plan (PEP)
• Is it a revision controlled document, with a
clear overview of the project
• It should have the requirements for design
for energy performance and energy
management, list the EED project objectives
and requirements for energy measurement,
monitoring and reporting
• The PEP should have project timelines for the
delivery of EED objectives, with a schedule of
meetings/reviews where the overall project
design will focus on EED.
• The lines of communication requirements
between the EED Owner, Expert and project
design team should be presented and clear,
as well as other interested parties
• The PEP should present a first initial EED
assessment of the project, including:
• Varying operating conditions
• Criteria for identifying SEU’s
• Criteria for determining if EED opportunities
will be incorporated into the project
scope/design and how they will be proven to
be successful
• The PEP should also comment on how the
procurement and contracting strategy will
support EED
• Consideration of national policies or other
mechanisms that could support the viability
of energy performance opportunities should
also be referenced at the outset.
• A list of identified risks and opportunities
related to the design project should be
considered - this is a precursor to
‘challenge and analyse’
9. Design for Energy Performance
(DfEP)
• Design for energy performance (DfEP) is a process comprising of an energy balance
study stage, challenge and analyse stage, and an implementation stage for design
projects.
• DfEP consists of:
Energy balance study
• Should be completed at URS stage and updated continually
as new information becomes available.
• A baseline is typically used to record the EED savings
against.
• The point at which baseline is taken depends on the type of
project; Greenfield/Brownfield/Replacement etc. and at what
stage EED is implemented (pre/post URS, pre/post contract
etc.).
Challenge and analyse
• Ideally carry this out as early as possible, with a number of
workshops:
• W/S 1: URS Stage – highest impact for lowest capex.
Typically EED Team, Designers and Client
• W/S 2: Pre-Contract – Still good commercial leverage with
preferred supplier. Typically EED Team, Designers, Supplier
and Client
• W/S 3: Post Contract / Detailed Design Stage – Usually
carried out at P&ID finalisation / Hazop stage. Typically EED
Team, Designers, Supplier and Client
Implementation
• Opportunities selected for implementation should be
reviewed and integrated into the design, construction and
commissioning project stages.
14. DESIGN FOR ENERGY PERFORMANCE (8.4.1)
• ENERGY BALANCE STUDY (8.4.2)
15. Energy Balance Study (8.4.2)
• The Energy Balance Study should be completed at URS
stage and updated continually as new information
becomes available.
• It is a baseline which is typically used to record the
EED savings against, but should use whatever
information is available to maximise return on the ‘EED
effort’.
• The point at which baseline is taken depends on the
type of project; Greenfield/Brownfield/Replacement
etc. and at what stage EED is implemented (pre/post
URS, pre/post contract etc.).
Consumption Breakdown Production Assumptions
Utility Assumptions
16. Energy Balance Study (8.4.2)
• Key Questions Include:
• What is the Energy Service?
• What are all the energy uses and energy sources?
• What are the significant energy uses?
• What are the expected running hours?
• What is the annual consumption?
• What is the peak demand for each utility?
• The Energy Balance Study should be completed at URS stage and
updated continually as new information becomes available.
• When carrying out the energy balance, you should be
thinking of the challenge and analyse phase as well. Some
initial questions that may arise include:
• Storage – thermal storage, battery storage etc.
• Heat Recovery
• Plant Turndown
• What grade of Utility is required?
• Question:
• What is the Energy Service for your project?
17. Energy Balance Study (8.4.2)
• The EBS should identify the type of utility consumed,
how much of it and why it is being consumed….
• This analysis focuses the challenge and analyse
activity….
18. Energy Service
Identifying the correct energy service is a
skillset/mindset
It can help push queries/opportunities beyond the intended
brief to areas where further opportunities can be unlocked:
19. Energy Service
The best EED analysis ensures opportunities can be disseminated
outside of the project group to the relevant stakeholders

32. Measurement and Verification
(8.4.4)
• Common Mistakes to avoid ahead of implementation
with respect to Measurement and Verification include:
• Setting EnPI’s and KPI’s that are difficult to measure
• EnPI’s based on peak plant output, plant never achieves peak.
• Selecting meters with insufficient accuracy or turndown.
• Not considering parasitic load from services
• Heat from pumps into liquid – negative impact on cooling consumption.
• Heat load from lighting into environment
• Not setting benchmarks for ‘baseload’ operation
• Potential to miss opportunity for Economy mode
• Too many meters – analysis becomes cumbersome
34. Design for Energy Management
(DfEM) (8.5.1)
• The process and controls integrated into the project design having an
objective to include provision for best practices in energy
management
• Provide a systematic approach within the design lifecycle to manage energy
consumption in operation and are intended to support the energy management
requirements of ISO 50001.
• It should broadly take place in the same timeline as DfEP.
• Energy Measurement Planning
• Energy Variables Review
• Energy Performance Deterioration
35. Design for Energy Management
(DfEM) (8.5.1)
The optimum output from DfEM is to implement in
same timeframe as challenge and analyse and ensure
outputs are captured in the ESR
36. Energy Variables (8.5.3)
What are Energy Variables?
• “quantifiable variable that impacts energy performance (3.21)”
• EXAMPLE: production parameters (production, volume, production rate), weather conditions
(outdoor temperature, degree days), operating hours, operating parameters (operational
temperature, light level)
Energy Variable Review
• Of SEUs to understand how Energy Performance affected by varying operating conditions.
• Challenge the design to ensure SEUs operate efficiently under expected or planned
variability in operating conditions.
37. Energy Performance Deterioration
(8.5.4)
Energy Performance
Deterioration
• “determine the potential for
deterioration in energy performance
during operations.
• Appropriate measurement & mitigation of this potential deterioration shall be considered
during the design stage.
• Output – Design Change, Metering, O&M procedures
• EXAMPLE: Fouling in Heat exchangers, HVAC Filters Blocking, Bearing wear etc, Lighting
Performance deterioration, Dirty Skylights- can you access easily to clean?
38. Energy Measurement Planning
(8.5.2)
Energy Measurement planning

Based on the experience to date,
there have been a number of
learnings, such as:
• If you are working on a project as an
EED Owner or EED Expert, you cannot
always ensure the process is followed
strictly.
• For example, a project may be
fast track and opportunity to
reduce energy consumption have
been missed.
• However, experience has shown
that once the process starts, there
are always opportunities to be
unlocked.
• The client usually needs to be
challenged more than the supplier!
Barriers that need to overcome to
maximise EED benefits include:
Specifications
Timelines
Budgets
Contracts
Perceived ’Hassle’ Factor

• Once the supplier understands EED, they are generally
positive – briefing them in advance of a workshop is a good
idea.
• Having a client sponsor with influence on capex is a key
criteria for success of EED in any project.
• It is important to review the register of opportunities with
the Project Manager before formal issue.
• They will ultimately be held to account for any proposed savings, so
they need to be comfortable with the calculations and assumptions
used.
• One of the key advantages EED can provide to a project is
looking at the areas surrounding the project and
determining positive and negative impacts on utility
consumption, as well as potentially larger opportunities
outside of the core project scope.
45. Learnings from Projects using EED
• Apply EED principles as early as possible to a project
Sometimes can be difficult in practice, many projects do not get funds
approved for engineering until the business case has been made and
approved.
By the times this happens, the URS may be ‘locked down’.
Trying to have the principles of EED applied earlier in the project
lifecycle affords greater opportunity to significantly impact the ‘energy
service’.
• Capturing the outputs of EED from projects and applying
them to subsequent projects is key.
By doing this, EED becomes a routine element of the project lifecycle,
in the same way as say, a Design Risk Assessment, or Hazop
• Co-ordination is key!
Good: Applying EED to a refrigeration plant and requesting a best in
class COSP.
Bad: Cooling distribution with high pipework pressure drops and too
tight of a temperature difference across heat exchangers.
Result: Lost EED Opportunity
46. Learnings from Projects using EED
• Carrying out EED at any stage in a project always yields
benefits, especially on smaller projects. Even if
opportunities are missed, they can be captured and
possibly remedied on subsequent projects.
• The importance of EED in delivering improvements in plant
throughput is sometimes missed.
Heat recovery projects, especially when applied to the main process
can also deliver reductions in heat up/cool down times.
• It is vital that the EED expert takes the time to look outside
of the boundary of the project to see if there are
‘integration’ type opportunities that could be realised by
good design.
