1/3/2016 Raising the temperature of the UK heat pump market: Learning lessons...Matthew Hannon
Heat pumps play a central role in decarbonising the UK's buildings sector as part of the Committee on Climate Change's (CCC) updated abatement scenario for meeting the UK's fourth carbon budget. However, the UK has one of the least developed heat pump markets in Europe and renewable heat output
from heat pumps will need to increase by a factor of 50 over the next 15 years to be in line with the scenario. Therefore, this paper explores what lessons the UK might learn from Finland to
achieve this aim considering that its current level of heat pump penetration is comparable with that outlined in the CCC scenario for 2030. Despite the two countries’ characteristic differences we argue they share sufficient similarities for the UK to usefully draw some policy-based lessons from Finland including: stimulating new-build construction and renovation of existing stock; incorporating renewable heat solutions in building energy performance standards; and bringing the cost of heat pumps in-line with gas fired heating via a combination of subsidies, taxes and energy RD&D. Finally, preliminary efforts to grow the heat pump market could usefully focus on properties unconnected to the gas-grid, considering these are typically heated by relatively expensive oil or electric heating technologies.

Reporting on the sustainability of district heating networksMirjamHarmelink
The Netherlands is aiming at a climate neutral build environment in 2050, in line with the goals of the EU. This implies that district heating networks will have to be nearly climate neutral as well. A number of Dutch heat suppliers annually reports on their contributions to a climate neutral energy supply. It is, however, often unclear how these reductions are calculated, i.e. which information is being used and what the underlying assumptions are.
The Dutch government therefore has introduced a reporting obligation for district heating suppliers. Under this obligation, it will be mandatory for suppliers to report annually on the sustainability of the heat supplied to their customers by providing at least information on: (1) CO2 emissions per unit of delivered heat, (2) Primary fossil energy use per unit of delivered heat and (3) the share of renewable energy sources.
To ensure that reported data are transparent and comparable, a mandatory uniform reporting format and method to calculate the three indicators was developed. It is based on existing definitions and methods that are already accepted and recognised by the stakeholders and in line with the buildings regulations. The methodology should provide insight on the actual sustainability of supplied heat by using annual measured data from the heat suppliers as well as annual monitoring data on e.g. the efficiency and CO2 emissions of the Dutch electricity production systems. This presentation outlines the methodology.

Design of Heat Exchanger Network for VCM Distillation Unit Using Pinch Techno...IJERA Editor
In process industries, heat exchanger networks represent an important part of the plant structure. The purpose of the networks is to maximize heat recovery, thereby lowering the overall plant costs. In process industries, during operation of any heat exchanger network (HEN), the major aim is to focus on the best performance of the network As in present condition of fuel crises is one of the major problem faced by many country & industrial utility is majorly depend on this. There is technique called process integration which is used for integrate heat within loop so optimize the given process and minimize the heating load and cooling load .In the present study of heat integration on VCM (vinyl chloride monomer) distillation unit, Heat exchanger network (HEN) is designed by using Aspen energy analyzer V8.0 software. This software implements a methodology for HEN synthesis with the use of pinch technology. Several heat integration networks are designed with different ΔT min and total annualized cost compared to obtain the optimal design. The network with a ΔT min of 90C is the most optimal where the largest energy savings are obtained with the appropriate use of utilities (Save 15.3764% for hot utilities and 47.52% for cold utilities compared with the current plant configuration). Percentage reduction in total operating cost is 18.333%. From calculation Payback Period for new design is 3.15 year. This save could be done through a plant revamp, with the addition of two heat exchangers. This improvement are done in the process associated with this technique are not due to the use of advance unit operation, but to the generation of heat integration scheme. The Pinch Design Method can be employed to give good designs in rapid time and with minimum data.
ECI position on the revision of the Energy Efficiency Directivefernando nuño
The European Copper Institute (ECI) supports the EU’s climate ambitions for 2030 and
2050 and welcomes the proposed recast of the Energy Efficiency Directive (EED). Copper is
a key material for energy efficiency in all sectors and contributes significantly to the clean energy
transition as a sustainable raw material that is essential to decarbonise the economy.
The EED recast proposal goes in the right direction in many areas. We welcome the
mainstreaming of the Energy Efficiency First principle and the strengthening of the
exemplary role of public buildings in driving renovation. The revised provisions on energy
audits and energy management systems are also useful to help small and medium-sized
enterprises (SMEs) catch up on energy efficiency measures, although we believe that mandatory
certification can be a barrier to the adoption of energy management systems by SMEs.
However, more needs to be done to facilitate the exploitation of the significant potential for
utilising waste heat from industrial processes under the EED. It is welcome that under the
revised article 23, Member States are mandated to take measures for district heating and cooling
infrastructure to be developed where benefits exceed costs.
However, in many cases it will not be possible to direct industrial excess heat to district heating
networks, and in such cases, the conversion of waste heat into electricity for own
consumption should be explicitly included under EED Article 23 as an energy savings
measure to be considered by Member States in the cost-benefit analyses underlying their
comprehensive heating and cooling assessments, and under Article 24 when assessing the
utilisation of waste heat on-site and off-site when large industrial installations are newly planned
or refurbished.
Finally, it is important to acknowledge that increasing energy efficiency will sometimes have an
impact on the realisation of other environmental objectives, such as environmental protection,
resource efficiency or decarbonisation. In some cases, decarbonisation measures such as
switching to low carbon energy sources or increasing energy system flexibility may reduce energy
efficiency, while the implementation of higher environmental protection standards can increase
energy demand. Policymakers should be mindful of such trade-offs and take care to avoid setting
conflicting targets.
Electric technologies in dwellings - potential for achieving EU emission targetsLeonardo ENERGY
Webinar on electric technologies in dwellings. Key findings of BSRIA study on the potential of heat pumps and photovoltaics in achieving EU emission targets.
When compared to gas condensing boilers, heat pumps achieve much better results in fighting CO2 emissions originating from dwellings in Europe. Their reduction potential even increases when combined with photovoltaics, particularly in countries where electricity generation bears a high CO2 conversion factor. That is the main conclusion of the BSRIA study “Electric technologies – Potential for achieving EU energy targets in residential dwellings (2013)”, commissioned by the Leonardo ENERGY initiative.
The study assesses CO2 emissions and lifecycle costs of various heat and/or electricity generating technologies, for both new and existing dwellings. By comparing several European countries (Germany, Sweden, Poland, Italy, Spain, France and United Kingdom), the study reveals that effective policies and support schemes by local governments help achieving energy efficiency and CO2 emission reduction targets at low end user cost.

Neuro-symbolic is not enough, we need neuro-*semantic*Frank van Harmelen
Neuro-symbolic (NeSy) AI is on the rise. However, simply machine learning on just any symbolic structure is not sufficient to really harvest the gains of NeSy. These will only be gained when the symbolic structures have an actual semantics. I give an operational definition of semantics as “predictable inference”.
All of this illustrated with link prediction over knowledge graphs, but the argument is general.

Elevating Tactical DDD Patterns Through Object CalisthenicsDorra BARTAGUIZ
After immersing yourself in the blue book and its red counterpart, attending DDD-focused conferences, and applying tactical patterns, you're left with a crucial question: How do I ensure my design is effective? Tactical patterns within Domain-Driven Design (DDD) serve as guiding principles for creating clear and manageable domain models. However, achieving success with these patterns requires additional guidance. Interestingly, we've observed that a set of constraints initially designed for training purposes remarkably aligns with effective pattern implementation, offering a more ‘mechanical’ approach. Let's explore together how Object Calisthenics can elevate the design of your tactical DDD patterns, offering concrete help for those venturing into DDD for the first time!

Optimisation of existing
District Heating and Cooling Energy
Introduction
Many of the DH&C systems in operation nowadays were built around or before
the 80s. During this time, technology has been developing at a staggering
speed while these DH&C networks remain inefficient and obsolete. The aim of
this info-package is to gather different possibilities for the optimisation of a
DH&C in an overall approach, not only with the purpose of improving its
performance, but also to obtain environmental benefits, due to the arising
awareness in nowadays society towards energy and greenhouse gases
emissions reduction. In this context, several measures are described in order
to pursue goals as CO2 emissions reduction, lead to energy and economic
savings, increase end users comfort and supply security.
Several strategies to comprise the customer needs could be coordinated at the
main energy transformation levels within a DH&C system: generation,
distribution, heat exchange and consumption. All the strategies are
approached in a general way and they can be applied in every DH&C, giving
replicable and systemic solutions.
Regarding the generation system, boilers and energy source could be changed
aiming to increase inertia, reduce energy consumption and achieve the
stabilization of the energy price. At energy distribution level, there can be
distinguished between two different actuations: design actions to reduce heat
losses and pressure drops, and operation actions as control strategies to
adjust different parameters to adapt to real energy needs stabilising network
loads.
In order to optimise the energy exchange in the buildings substations, it is
essential to coordinate the generation and distribution to the end users
consumption profiles, while at end users consumption level, it would be
appropriate that they could adapt their energy consumption according to their
desired comfort level.
The following figure shows a scheme of the main energy levels above
mentioned and different actuation fields within these in order to optimise a
DH&C.

Optimisation of existing
District Heating and Cooling Energy
Goals
• Minimise the investment costs in the generation plant, by the optimisation of the
generation power. Simulations of the energy demand together with real data and
determining a global profile optimise the generation equipment. In addition, back-up
boilers from the original generation system could be maintained to supply peak loads.
• Optimise the generation by the installation of energy storage systems that smooth the
demand profile, and reducing the flow temperature set point. A low return water
temperature enables an efficient use of energy sources, increase the transmission
capacity, reduce heat losses and reduce pumping energy demand.
• Minimise GHG emissions by the use of at least 50% of renewable sources of energy. It is
possible to use biomass, waste thermal energy from already working plant or integrate
solar energy in the circuit.
• Reduce 15% heat losses in the distribution system by the layering in thermal storage
tanks, and pressure drops by actions in the distribution system during the design phase
which comprises the optimal design of the pipelines layout. Switch on/off strategies
reduce thermal losses in the distribution and generation power minimising peaks in
demand.
• Increase the efficiency of the system at least in a 5% of the performance and reduce the
district energy consumption by adapting the energy distribution and production to end
users real demand by the use, among others, of variable flow pumping system.
• Adapt the operation conditions to the real heat needs by control strategies to adjust
different parameters as the supply temperature and the flow rate, keeping constant one of
the two variables alternatively.
• Integrate a smart centralised control and monitoring system that ensures that the system
responds to the demand. With this measure we manage to optimise the energy balance
between the network and the substations.
• Achieve an appropriate coordination of the generation, distribution and energy exchange
control strategies in order to anticipate the response to the variations in the demand
profile. The substations constitute a connection point between the overall optimisation
strategies for the generation and distribution levels and the end users demands.

Optimisation of existing
District Heating and Cooling Energy
Progress
The demonstration of the above described measures for the optimisation of
existing DH in Valladolid is fully considered in the design phase in all the
energy levels (generation, distribution, energy exchange and end users),
and would be implemented in the coming months.
In Nottingham, the DH system is being used to supply Low Temperature
District Heating; this is optimisation of DH using the return heat on the
system at a lower temperature and using it in conjunction with a new
efficient distribution system to extend the network to customers with a lower
energy demand.
In Tepebaşı demo site, the DH system was supplied by individual heating
via combi boiler at each building. However, optimised system provides low
temperature central district heating (45-55 °C). In addition, energy source
optimisation is ensured by using renewable electric energy and organic
waste (pellet) instead of using natural gas.
Lessons learnt
01 It is feasible to optimise an existing District Heating and Cooling network.
02 It is possible to optimise a DH&C partially by implementing measures
regarding only some of the energy levels, taking into account that the
decisions made in one of the energy levels, inevitably would influence in
the rest of them.
03 In order to obtain the higher impact by the optimisation of the DH&C it is
advisable to implement measures in every energy level.
04 The optimisation of a DH&C is a process which is highly recommended to
be considered during the whole life of the network.
