As part of policy of having the right test equipment necessary, LHW have invested in a power quality analyser, and upgraded to latest handheld IR equipment to allow GPS and wifi, in addition to exisitng PV modelling test equipment and DC power supply & EL camera. This wil help renewable & energy efficiency aspects of business.
Following successful PV installation of 75kWp, a local authority engaged LHW to undertake a feasibility for adoption of heat pumps at a large 85 bed education and outdoor centre. This included IR verified heat loss, and full review of ASHP, Borehole and Ground collector systems.
In a month when travel was challenging, LHW were engaged and completed over 30 PV simulation models for clients ranging from 30kWp to over 300MWp, including roof top, and ground mount in locations from Columbia, Ireland, Lake District and a pan national warehouse portfolio. In all over 400 MWp of projects were modelled.
In March, LHW undertook a number of building heat loss surveys in the City of London, and elsewhere. The work resulted in a development of a system modelling tool for pragmatic determination of building "U" values of ageing building stock, fundamentally important for heating system improvement.
LHW is providing Technical Advisory services and Siite Acceptance inspection and reporting for a London Community Energy organisation and one of the UK's largest County Councils for nine PV rooftop and ground mount installations comprising over 500kWp of installed capacity
LHW have completed a detailed feasibility assignment for two NHS Trust Hospitals in England reviewing a range of options including rooft top and retrofit of car ports. As a large energy user the NHS is loooking at ways to energy reduce costs and CO2 emmisions in a cost effective manner.
In the first PV farm investogation of 2020, LHW undertook a range of daylight testing on a system, identifying low shunt resistance (PID) as the probable reason for system under performance. The testing , a scientifically correct and yet not a recognised mainstream IEC testing methodology helps provide a large amount of additional information on PV system performance issues.
