LHW Partnership have completed a successful tender review exercise to a point of contract award with the selected contractor for a 200kWe Ground Source Heat Pump System at Wimpole Hall in Cambridgeshire.
Having previously undertaken heat loss and site surveys and prepared a technical specification, LHW can look forward to the technical advisor’s role when the installation starts in the new year.
There were some interesting solutions proposed, and in particular angled boreholes to minimise ground space utilisation.
LHW are currently preparing a technical specification for a matching ground based PV array, and have produced layout drawing options for Heritage and Planning review.
LHW Partnership have completed an ESOS type Energy Audit of the Emmaus Village in Carlton in North Bedfordshire.
Emmaus Village Carlton is a homelessness charity offering active support to formerly homeless people, and provide a real workable alternative to homelessness, offering people a home, as well as meaningful work in the social enterprise.
A review of the energy tariffs, electrical, water and heating systems, and handheld and drone mounted infra-red surveys to identity poorly performing technology
There were a number of principal aspects identified, and both renewable and energy efficiency solutions proposed offering both viable financial and 155 tonnes per annum C02 reduction.
LHW Partnership have released a video showreel of some of the interesting projects taken around the UK and Ireland over the last 12-18 months.
The videos abd images range from wind turbines, ground and buildng mounted solar PV arrays, coastal features, stunning scenery, and even a human "Crusaders" made up of enthusiastic children on a training week in Norfolk.
Sadly there were many to many to choose from and not all could be aired, and we chose to avoid some of the more technically oriented images which is the core activity. Please click here or on the image on the right to see the video.
LHW Partnership have completed a due diligence undertaking for a major energy focused Interational Consulting Engineer.
The project the first for LHW in the Middle East ws a due diligence exercise for a large ground mounted PV project in Oman, and the power will feed a desalination plant. As a comparison to the UK the generation per kWp is about 40% more but the panels run a lot hotter so dont work as well as in UK.
LHW Partnership were engaged by Billington Parish Council to provide a feasibility study to improve the energy performance of the village hall.
A number of technologies were found to be feasible including PV, and most notably basic insulation improvements, as there was no ceiling insulation and the air to air heat pump was losing heat through the roof. Curtains were an additional augmentation that was recommended as low cost and effective, as there are a large number of windows in the building with no curtains, and the the heat could be retained. The study did not advise LED replacement as the existing lighting is relatively new, and the lighting is not used very often. The air to air heat pump was the single largest energy consuming component. The PV would offset the energy consumption of the heat pump on an annualised basis that than real time. It was recommended to fit a Half Hourly meter to record energy consumption, so energy storage could be adopted in the years to come.
LHW were able to use infra-red aerial inspections though the building was close to the main road, the CAA approval granted to LHW allows a 20 meter area of control, so requiring control of the road was not an issue.
LHW Partnership have been engaged by St Georges School, Leigthon Buzzard to look at the energy perfomance, and possible renewable energy initiatves for community ownership.
As pat of the engagement an aerial Infra Red survey was undertaken demonstrating the building heat loss is a very visible form.
The school is looking at ground source heat pump technology, as there are several acres of playing fields
LHW Partnership have been engaged by Ovesco, based in Lewes to undertake feasibility of Solar PV and other technologies for schools and other interested parties in the East Sussex area.
Over 14 locations have been visited, and grid connection, Half Hourly demand and generation appraisals have been undertaken to optimise the size, and avoid excessive export. A technical tender specification has been prepared for each project for tendering , and aerial photographs and case studies of the completed projects are being prepared.
LHW Partnership have been accepted as affiliate members of the UK Thermography Authority, part of the British Institute of Non Destructive Testing.
With increasing recognition of the benefits of Infra Red imaging in the renewable and energy efficiency sectors with the identification of building heat losses, and technology anomalies, and the recent recognition of the importance in building energy in the Governments Clean Growth Plan, it is a natural step to accelerate learning and mix with fellow professionals and share best practice.
LHW Partnership has undertaken a multitude of Energy Feasibility appraisals for clients and operators in the Water, Transportation, Aggregates, Poultry & Agricultural,Fisheries and Logistics sector to optimise the PV/Wind generation, on site demand, export constraints and optimising the adoption energy storage, on a Half Hurly Modelling basis. The system developed in house, can accommodate all generation types on a HH basis, and HH PV data can be simulated for any system.
The system called Yieldworks is predominantly behind the meter based and can factor in DUoS rates, CCL, Triads, on a kWh and monetorised basis, but also has the flexibility to augment revenue models with grid service appraisal for the energy storage.
LHW Partnership LLP actively supported a successful planning application for a second 1.5 MW wind turbine planning application in its home town of Leighton Buzzard, in the face of strong opposition locally.
LHW were able to provide technical advice to people in the community on the less clear aspects of the renewables mix.
These included comparative data on seasonal Wind & PV generation profiles, embodied energy, capacity factors, and the comparative costs of grid development, the looming energy gap and nuclear issues.
The planning process was typified by a significant amount of creative information that was less than supportive of wind technology, and LHW was able to utilise 25 years of renewable and wind industry experience to help educate people who wanted honest information not always easily available
Over the summer LHW has undertaken Ground based infra-red inspections of over 50MWp of PV Systems ranging from roof mounted through to ground array PV installations, and provided IEC compliant reporting on the findings. The work has involved both PV module installation, as well as balance of plant including Inverters, Sub & main LV distribution boards, and HV equipment (transformers & switchgear)
LHW has developed a toolbox of Infra Red solutions for Ground based, roof mount, using drones, vehicle mounted, handheld stabilised gimbal and pole mounted platforms, enabling investigation in urban areas as well and in more rural areas.
Issed encountered and identified include PID, By-Pass diode failures, soiling from dirt build up, vegetation occlusion, and single multiple hot cells from potential manufacturing issues.
Today is the 4th anniversary of the establishment of LHW Partnership LLP.
Against a backdrop of an almost total removal of Government support for renewable energy, LHW Partnership LLP has completed over 500 varied engineering projects in PV, Solar Thermal, Biomass, Heat Pumps, Wind, Anaerobic Digestion, CHP and energy efficiency.
An enviable client list has been built up and LHW has been heavily involved with some of the most innovative Renewable Energy projects in the UK and probably the world, and has taken a market leading position in renewable energy and energy storage software modelling, aerial inspection work with a special CAA licence for aerial work in congested areas, and forensic capability in inspection work with infra red and electrical analytical inspection capability.
With thousands of people and companies forced to close or leave the industry, LHW has focused on the future of the industry, and it is beyond doubt this sector is the future.
On this day a special thanks to all the clients, friends, family and supporters who have helped make it happen.
LHW Partnership LLP have secured a 2 year contract to undertake aerial photographic and video services of a sustainable construction project involving the reclamation of a quarry in the Leighton Buzzard area and conversion into sustainable housing and landscape.
LHW Partnership LLP will record the progress of the project twice a week until project completion. The service commnenced in April 2017.
The project will involve the use of 2 UAVs , the CAA approved Hexacopter with congested area appproval and Sony A6000 / Panasonic GH4 , and also the Yuneec Typhoon H Hexacopter.
LHW Partnertship hold PFCO and a 20 metre congested area approval, making them one of very few orgnaisiations in the UK approved ot survey schools and other buildings which a stanard licence with a 50 metre appproval would not accomodate.

LHW Partnership LLP are providing visual, infra red inspection and photography services to clients in the UK.
We can operate in rural locations with land owner's approval as well as in urban, more congested areas as we hold CAA approval to operate with a 20 metre area of control for such work.
LHW Partnership LLP have been awarded Operational zone of control area permission by the Civil Aviation Authority of 20 metres radius to undertake aerial inspection work. This means that a distance of 20 metres around the drone is required, as opposed to the standard 50 metres, which is very restrictive in built-up areas.This will enable the facilitation of visual and infra red inspection of schools, urban buildings, that were previously not legally possible.
The approved aircraft is a hexacopter, with dual flight controller, dual GPS, dual power supplies, emergency parachute and prop guards, and is the result of 12 months safety case preparation, approved by the CAA in December 2016.
The Unmanned Aerial Vehicle (UAV) can carry visual and infra red camera technology.
LHW Partnership LLP holds fully PFCO approval, OSC approval for 20 metres, is qualified and insured, and holds level 2 infra red qualifications, to sign off infra red inspection reports. This is a requirement of the forthcoming IEC PV system inspection technical standard.
LHW Partnership LLP have been awarded a contract by Siemens to provide engineering services including inspection and routine maintenance on the PV Array at the Crystal Building in Docklands.
The 120 kWp array was commissioned in 2012, and LHW Partnership LLP will provide testing and maintenance services including Infra Red inspections, IV curve verification, and routine maintenance in line with the IET PV Code of Practice.
Siemens opened the Crystal in 2012 as a global hub for debate on sustainable living and development. Since opening, over 100,000 people each year have visited the interactive exhibition; thousands of meetings and events have been hosted in our sustainable events venue; and numerous major projects have been undertaken in the Siemens office on-site.
The Crystal sets the benchmark for sustainable building design. It is the only building in the world to achieve the highest certification in both the BREEAM and LEED schemes, as well as many other accreditations. Siemens technologies throughout the building ensure the highest energy efficiency and CO2 standards are met.
Designed by LHW Partnership LLP, and commissioned in 2014, the largest tracker ground mount system in the UK at 248 kWp is set to generate just short of 300 MWh in 2016. the same system generated 300MWh in 2015 which had a far better generating period in the June 2015 period.
Comparative models of a fixed non tracked system estimate the yield to be 241 MWh per annum, so for the second year running the system has generated 25% more energy than a fixed system, making it almost certainly the most efficient and effective larger scale ground mount PV generation system in the UK in terms of kWh generated per kWp.
LHW Partnership LLP along with the CLA are featured in an article on "behind the meter" energy storage benefits in last weeks Farmers Guardian. LHW Partnership LLP advocate a proper demand side energy audit, before investment as returns on investment are very much dependant on energy export offsets, and there are some very ambitious and unrealistic claims being communicated to prospective customers. An energy audit will determine the benefits and return on investment. See Farmers Guardian article here
Alongside other industry leaders, LHW Partnership LLP have been invited to present in the Energy Storage seminar on a topic called "Behind the meter - using storage to minimise export and maximise on site demand”, at the Energy Now Expo in Telford in 2017.
The presentation will allow the audience to hear about the importance of knowing your energy demand profile, and generation profile, and how careful data collection, modelling and system size optimisation can ensure a good project is developed and delivered.
Other speakers include the Energy Storage Network and the CLA, and the audience will be Rural and Agricultural stakeholders. More information is available here
The 2 partners at LHW Partnership LLP have had a technical paper approved for publication by the Institution of Engineering & Technology in the Engineering & Technology Reference section. The paper written by Laura Jones & James Hoare is titled 'Maximising and optimising solar PV generation with limited grid capacity by adopting new technology'.
The paper covers the background contexts and issues, the technology application benefits, and provides 4 pragmatic examples of successful installation where the technology application can be demonstrated.
The paper will be released in November 2016 by IET for members.
We are pleased to announce that LHW Partnership LLP is now offering half hourly modelling for solar PV and energy storage systems. The YIELDWORKS modelling software, which has been in development for 2 years, can incorporate any system size and technology combinations, providing a granular appraisal of the viability of battery storage systems.

September 2016 Update
This month LHW Partnership LLP is launching a renewable and energy storage management modelling service offering.
End Users (home owners up to and including Half Hourly metered and utility scale), installers, funders and communities will be able to appraise the effectiveness of implementing an energy storage system to supplement Solar PV, wind and also other less intermittent generating systems.
The modelling software can accommodate single and multi-facing PV systems, with either satellite or ground based meteorological data, historic Half hourly consumption data, simulated or recorded domestic consumption data at 5 minute intervals, network operator export constraint allowances, varying battery technologies, immersion heater diversion. It can also accommodate future energy demand reductions from LED implementation and other future energy efficiency technology innovations.
LHW Partnership LLP have published a guide to maximising PV Size, when there is a network constraint. The system based around HH modelling of PV & energy demand provides designers and developers with the opportunity to maximise / optimise the PV system sizing without being too conservative of having unacceptable yield constraints.
As part of the CLA Rural Business 2030 conference being held in London in December, the CLA are holding an Energy Seminar on September 6th at Hotel Du Vin in Birmingham.
The aim of the day is to bring a group of experts and CLA members together to put together some rural energy policy ideas looking towards 2030 as part of our Rural Business 2030 conference. LHW Partnership LLP are delighted to have been asked to present on the subject areas of
- Energy self sufficiency in the context of national energy policy & benefits for rural businesses.
- How can rural businesses move towards self sufficiency in heat and power.
- Is energy self sufficiency a realistic expectation by 2030.
It is now possible to follow the UK's grid activity by visiting Gridwatch. In particular, it is possible to follow the contributions of renewable and low carbon technologies to the UK energy mix.
Both Partners at LHW Partnership LLP are now Level 2 certified thermographers qualified to undertake thermographic surveys. Infrared thermography technology can be used to inspect ground mounted and roof mounted solar PV systems and thermographic surveys are now a feature of BREEAM, the world’s leading environmental assessment method and rating system for buildings.
BREEAM New Construction and BREEAM Domestic Refurbishment programs both recognise the benefit of thermographic surveys by awarding credits for Level 2 certified thermographers undertaking suitable thermal surveys.
LHW Partnership have recently completed the Site Acceptance test on a 500 kWp project on behalf of Prater for the new BSkyB Headquarters building near Isleworth in West London.
LHW Partnership were also engaged as Technical Advisors for the first phase of the project, providing system modelling services, technical advice on the use of PV module optimisers for fire alleviation to the lead project consultant (Arup), providingtechnical submissions and undertaking a technical review of contractor proposals. Following the completion of the installation work LHW Partnership conducted a site inspection to ensure all aspects of the system were in accordance with the new IET PV Code of Practice.
LHW Partnership, working in partnership with CLS Energy have undertaken an ESOS audit and appraisal report for the Landmark Trust. The portfolio of 195 buildings and associated transport infrastructure are some of the most unusual in the UK encompassing accommodation in Castles, Chapels, Light Houses, Gothic Temples, Railway Stations, Historic Towers and a wealth of interesting historic buildings.
The Landmark Trust offer short breaks in restored historic buildings, and are charity that gives new life to interesting and historic buildings for the benefit of the public at large.
LHW Partnership were engaged as Technical Advisors on a 2.3MWp ground based PV farm located south east of Leicester. The system was commissioned to meet the ROC deadline of 31/3/16 and comprises JA Solar 315 Wp modules with on board optimisers in a landscape orientation with 73 SolarEdge 27.6 kVA inverters. The system was designed to be one of the most efficient solar farms in the world by adopting technology not previously adopted for large scale ground mount systems, and will provide the client with real time performance information on each of the 8000 modules.
