Five actions fit for 55: streamlining energy savings calculationsLeonardo ENERGY
During the first year of the H2020 project streamSAVE, multiple activities were organized to support countries in developing savings estimations under Art.3 and Art.7 of the Energy Efficiency Directive (EED).
A fascinating output of the project so far is the “Guidance on Standardized saving methodologies (energy, CO2 and costs)” for a first round of five so-called Priority Actions. This Guidance will assist EU member states in more accurately calculating savings for a set of new energy efficiency actions.
This webinar presents this Guidance and other project findings to the broader community, including industry and markets.
AGENDA
14:00 Introduction to streamSAVE
(Nele Renders, Project Coordinator)
14:10 Views from the EU Commission and the link with Fit-for-55 (Anne-Katherina Weidenbach, DG ENER)
14:20 The streamSAVE guidance and its platform illustrated (Elisabeth Böck, AEA)
14:55 A view from industry: What is the added value of streamSAVE (standardized) methods in frame of the EED (Conor Molloy, AEMS ECOfleet)
14:55 Country experiences: the added value of standardized methods (Elena Allegrini, ENEA, Italy)

This is the second in a series of 'Show and Tell' webinars from the Ofgem Strategic Innovation Fund Round 1 Discovery phase, covering the Heat projects.
Consumers need better access to low-carbon heating options which remain reliable and affordable in comparison to existing solutions. For many domestic, commercial, and industrial end consumers, heat comprises a considerable proportion of their energy bills.
There are a variety of technologies which could potentially contribute to heat decarbonisation. These include heat networks, electric and hybrid heat pumps, hydrogen, biofuels and others.
As examples, you will hear from SIF projects working on developing the gas networks to adapt to hydrogen, and electricity networks exploring the use of thermal energy storage as a source of flexibility.
The Strategic Innovation Fund (SIF) is an Ofgem programme managed in partnership with Innovate UK, part of UKRI. The SIF aims to fund network innovation that will contribute to achieving Net Zero rapidly and at lowest cost to consumers, and help transform the UK into the ‘Silicon Valley’ of energy, making it the best place for high-potential businesses to grow and scale in the energy market.

This is a compilation of the overall process in conducting energy audit based on my personal experiences, training that I attended in Malaysia, India and Japan and information sharing between fellow EE practitioners.Not to forget references from books and internet.
I believe this would benefit to those who wants to understand what is energy audit all about for beginners to become energy auditor and to facilities owners to assess the need to conduct energy audit and energy audit proposals submitted by consultants
The energy model on which the majority of cities in developed countries are based upon is characterized by centralization and unsustainability. Barcelona, being a Mediterranean city, faces the challenge to increase its solar energy supply, moving towards a more sustainable energy model, while strengthening the network's business sector.
ASCAME is committed to this initiative, in the framework of the European project FOSTEr in MED gathering together in the auditorium of the Chamber of Commerce, Industry and Navigation of Barcelona, several experts in the field of renewable energy, as well as companies, public authorities, universities and organizations that will analyse the state of sector, its’ trends and the business development scenario emerged.

Cancer cell metabolism: special Reference to Lactate PathwayAADYARAJPANDEY1
Normal Cell Metabolism:
Cellular respiration describes the series of steps that cells use to break down sugar and other chemicals to get the energy we need to function.
Energy is stored in the bonds of glucose and when glucose is broken down, much of that energy is released.
Cell utilize energy in the form of ATP.
The first step of respiration is called glycolysis. In a series of steps, glycolysis breaks glucose into two smaller molecules - a chemical called pyruvate. A small amount of ATP is formed during this process.
Most healthy cells continue the breakdown in a second process, called the Kreb's cycle. The Kreb's cycle allows cells to “burn” the pyruvates made in glycolysis to get more ATP.
The last step in the breakdown of glucose is called oxidative phosphorylation (Ox-Phos).
It takes place in specialized cell structures called mitochondria. This process produces a large amount of ATP. Importantly, cells need oxygen to complete oxidative phosphorylation.
If a cell completes only glycolysis, only 2 molecules of ATP are made per glucose. However, if the cell completes the entire respiration process (glycolysis - Kreb's - oxidative phosphorylation), about 36 molecules of ATP are created, giving it much more energy to use.
IN CANCER CELL:
Unlike healthy cells that "burn" the entire molecule of sugar to capture a large amount of energy as ATP, cancer cells are wasteful.
Cancer cells only partially break down sugar molecules. They overuse the first step of respiration, glycolysis. They frequently do not complete the second step, oxidative phosphorylation.
This results in only 2 molecules of ATP per each glucose molecule instead of the 36 or so ATPs healthy cells gain. As a result, cancer cells need to use a lot more sugar molecules to get enough energy to survive.

introduction to WARBERG PHENOMENA:
WARBURG EFFECT Usually, cancer cells are highly glycolytic (glucose addiction) and take up more glucose than do normal cells from outside.
Otto Heinrich Warburg (; 8 October 1883 – 1 August 1970) In 1931 was awarded the Nobel Prize in Physiology for his "discovery of the nature and mode of action of the respiratory enzyme.
WARNBURG EFFECT : cancer cells under aerobic (well-oxygenated) conditions to metabolize glucose to lactate (aerobic glycolysis) is known as the Warburg effect. Warburg made the observation that tumor slices consume glucose and secrete lactate at a higher rate than normal tissues.
Richard's aventures in two entangled wonderlandsRichard Gill
Since the loophole-free Bell experiments of 2020 and the Nobel prizes in physics of 2022, critics of Bell's work have retreated to the fortress of super-determinism. Now, super-determinism is a derogatory word - it just means "determinism". Palmer, Hance and Hossenfelder argue that quantum mechanics and determinism are not incompatible, using a sophisticated mathematical construction based on a subtle thinning of allowed states and measurements in quantum mechanics, such that what is left appears to make Bell's argument fail, without altering the empirical predictions of quantum mechanics. I think however that it is a smoke screen, and the slogan "lost in math" comes to my mind. I will discuss some other recent disproofs of Bell's theorem using the language of causality based on causal graphs. Causal thinking is also central to law and justice. I will mention surprising connections to my work on serial killer nurse cases, in particular the Dutch case of Lucia de Berk and the current UK case of Lucy Letby.
THE IMPORTANCE OF MARTIAN ATMOSPHERE SAMPLE RETURN.Sérgio Sacani
The return of a sample of near-surface atmosphere from Mars would facilitate answers to several first-order science questions surrounding the formation and evolution of the planet. One of the important aspects of terrestrial planet formation in general is the role that primary atmospheres played in influencing the chemistry and structure of the planets and their antecedents. Studies of the martian atmosphere can be used to investigate the role of a primary atmosphere in its history. Atmosphere samples would also inform our understanding of the near-surface chemistry of the planet, and ultimately the prospects for life. High-precision isotopic analyses of constituent gases are needed to address these questions, requiring that the analyses are made on returned samples rather than in situ.
Multi-source connectivity as the driver of solar wind variability in the heli...Sérgio Sacani
The ambient solar wind that flls the heliosphere originates from multiple
sources in the solar corona and is highly structured. It is often described
as high-speed, relatively homogeneous, plasma streams from coronal
holes and slow-speed, highly variable, streams whose source regions are
under debate. A key goal of ESA/NASA’s Solar Orbiter mission is to identify
solar wind sources and understand what drives the complexity seen in the
heliosphere. By combining magnetic feld modelling and spectroscopic
techniques with high-resolution observations and measurements, we show
that the solar wind variability detected in situ by Solar Orbiter in March
2022 is driven by spatio-temporal changes in the magnetic connectivity to
multiple sources in the solar atmosphere. The magnetic feld footpoints
connected to the spacecraft moved from the boundaries of a coronal hole
to one active region (12961) and then across to another region (12957). This
is refected in the in situ measurements, which show the transition from fast
to highly Alfvénic then to slow solar wind that is disrupted by the arrival of
a coronal mass ejection. Our results describe solar wind variability at 0.5 au
but are applicable to near-Earth observatories.

Earliest Galaxies in the JADES Origins Field: Luminosity Function and Cosmic ...Sérgio Sacani
We characterize the earliest galaxy population in the JADES Origins Field (JOF), the deepest
imaging field observed with JWST. We make use of the ancillary Hubble optical images (5 filters
spanning 0.4−0.9µm) and novel JWST images with 14 filters spanning 0.8−5µm, including 7 mediumband filters, and reaching total exposure times of up to 46 hours per filter. We combine all our data
at > 2.3µm to construct an ultradeep image, reaching as deep as ≈ 31.4 AB mag in the stack and
30.3-31.0 AB mag (5σ, r = 0.1” circular aperture) in individual filters. We measure photometric
redshifts and use robust selection criteria to identify a sample of eight galaxy candidates at redshifts
z = 11.5 − 15. These objects show compact half-light radii of R1/2 ∼ 50 − 200pc, stellar masses of
M⋆ ∼ 107−108M⊙, and star-formation rates of SFR ∼ 0.1−1 M⊙ yr−1
. Our search finds no candidates
at 15 < z < 20, placing upper limits at these redshifts. We develop a forward modeling approach to
infer the properties of the evolving luminosity function without binning in redshift or luminosity that
marginalizes over the photometric redshift uncertainty of our candidate galaxies and incorporates the
impact of non-detections. We find a z = 12 luminosity function in good agreement with prior results,
and that the luminosity function normalization and UV luminosity density decline by a factor of ∼ 2.5
from z = 12 to z = 14. We discuss the possible implications of our results in the context of theoretical
models for evolution of the dark matter halo mass function.

6. Heat planning and governance
Heating is a local demand
• Unlike electricity and gas, heating is situated locally
• Often overlooked in national energy policy
If not treated systematically in energy policy and governance:
• Significant sector coupling and synergies are missed
• Many renewable or efficient heat sources are not considered
7. Strategic energy planning
• The purpose of Strategic Energy Planning is to address issues with current energy
supply and to formulate strategies and plans for transitions.
• Strategic heat and cooling planning does differ from planning for other energy carriers
due to the local nature of heating and cooling supply.
• Interdisciplinary: available resources, energy demands, technical potentials, current
legislation, the organisation of the energy sector and the related actors, political
drivers and barriers should be considered

10. Scope, Purpose and Stakeholders in Strategic Heat Planning
Scope, Purpose and Stakeholders
• Important to identify drivers of the strategic energy planning process:
• Climate change, energy security, pollution, energy poverty etc..
• Multiple drivers are likely to exist: important to figure out which ones align
Identification and coordination of stakeholders
• Who are the main actors engaged in the process
• Industry, high demand consumers, consumers with special needs
• Identifying opportunities to involve stakeholders that can play a constructive role in realizing heat
plans
• Identifying synergies and opportunities for cost-effective district energy systems
11. Scope, Purpose and Stakeholders in Strategic Heat Planning
Some Stakeholders to Consider:
- National Authorities
- Local Authorities
- Utility Companies
- Investors
- Researcher / Academia
- Developers
- Technology developers: geothermal, solar
thermal, PV, wind etc.
- Excess heat suppliers: industry
- Customers and Citizens
12. Scenario building
1. Quantify and locate heat demand
2. Quantify and locate heat resources
3. Quantify and assess heat-saving potentials
4. Establish scenarios for heat supply
13. Scenario building for strategic heat planning
1. Quantify and locate demands
• Measurements of actual demands allow for actual knowledge of distribution of
consumption.
• Modelling or estimating demands can be a way forward to provide inputs for
decision making – see for example Peta4 and Hotmaps.
Heating demand Budapest Cooling demand Budapest
From Hotmaps
14. Scenario building for strategic heat planning
2. Quantify and locate heat resources
• Strategic heat sources are typically either excess heat or renewable sources
• Low district heating supply temperature enables the use of low temperature geothermal resources
• Strategic heat sources can thus be low-temperature decentralised renewable such as solar thermal,
geothermal heat, or excess heat recovered from compressor machines

16. Scenario building for strategic heat planning
4. Establish scenarios for heat supply
• When establishing these scenarios, keep in mind the i)scope, ii) perspective and iii) timeframe of
energy systems analysis
• Do not make them too detailed at first! Easy to get lost in technical or legal details. It is important
to keep the process moving. Include the level of detail needed to make decisions and move further.
17. Scenario building for strategic heat planning
Methodological points for scenario building:
- Energy system scope:
- Include entire energy system to identify synergies
- Data is important:
- Good quality heating data is vital
- Timeframe:
- Ensure that scenarios are in line with long-term targets
- Differentiate between socio-economic and business economic prices:
- Taxation, subsidies, externalities etc. influence the result. Use costs
that are relevant to society and not supporting status quo.
- Important to remember that strategic heat planning is not business as
usual

19. Enabling Framework Conditions, Financing and Business Models
Three typical barriers:
Challenge 1: Level playing field
Recommendations:
• Fiscal levers
• Specific district heating legislation
• Consider district heating grids as infrastructure
• Consider externalities: decarbonisation, supply security, air quality
Challenge 2: Lack of governance tools to implement district heating
Recommendations:
• Feed back needs and ideas to national authorities and legislature. Create awareness of lacking tools.
• Identify what is possible within current regulatory framework
Challenge 3: Overcoming barriers to investment
Recommendations:
• Picking low-hanging fruits: start with high-demand consumers,
• Government intervention through economic and financial instrument
• Capacity building for authorities and heat market stakeholders

Editor's Notes
Heating is the largest end-use in Europe
Heating accounts for around 50% of total energy consumption
High potential for energy savings and district heating. In Europe around 50% district heating and 30% heat savings
District heating allows access to many supply sources
Geothermal ressources, large-scale heat pumps, excess heat, solar thermal
Thermal storage
Smart energy systems (sector coupling)
District energy can contribute to the transition towards an energy system that integrates smart electric, thermal, gas grids and larger amounts of fluctuating renewable resources
Serbia residential heat consumption is around 20-25% of Primary Energy Consumption
Odysse + Eurostat
Residential: 34.36 TWh (WITHOUT losses)
Primary: 173.2 TWh
~=20%
The policy scale – several interest and needs must be aligned. Local/strategic heat planning is carried out in the context of regulation ”from above”
The energy system – important to avoid suboptimisation or over use of certain ressources. Therefore SEP must take the broader energy system into context – both to exploit synergies but also avoid suboptimisation

Technical heat mapping
Quantify and locate heat demand
Quantify and locate heat resources
Quantify and assess heat-saving potentials
Establish scenarios for heat supply
Challenge 1: establishing the demand for heating requires the acquisition of data on energy consumption from buildings as well as the dynamics of the demand e.g. how demand changes over time. This data is not readily available, especially in relation to space heating and cooling.
Solution/tools to challenges 1 – Expand energy metering and measurement to gain knowledge of energy demand, mapping of current building stock to enable estimations of potential energy savings and feasibility of low-temperature supply, modelling or estimating the heat demand using available tools /PETA 4 and Hotmaps toolbox

The Energy efficiency first principle
Assess the costs of different energy-saving measures and implement the ones that are cheaper than the cost of energy supply.
Energy efficiency measures have a supply chain effect
Building renovation measures usually implemented with very long time frames, thus not always feasible to postpone a district energy project until certain energy efficiency potentials have been realised.

JINAN
In recent years, China has attached great importance to clean heating and has introduced a series of policies to promote, support and accelerate the promotion of clean heating.
Jinan, as one of the national pilot cities of "winter clean heating", has received ¥700 million of special financial support from the central government annually, or ¥2.1 billion for 3 years in total.
Under the impetus of the national clean heating policy, Jinan has formulated a relatively perfect clean heating policy system by 2020. The development of district energy in Jinan is inseparable from the promotion of policies.
BELGRADECase study: the City of Belgrade created Energy efficiency Fund as a financing pool for buildings renovation and district heating. Public buildings are scheduled first as demo projects. Capacity building for the municipality and involved stakeholders.
Belgrade formed an Energy Efficiency Fund for renovation of public and residential building, but also in order to expand their district heating network.
With high levels of energy demand savings on the building side through renovation, it can become more cost-effective to pursue sustainable energy supply options, like district energy based on renewable energy or excess heat, for the remaining energy demand. This means the opportunity to expand the district heating network without increasing installed heat capacity.
