Syntegra Consulting Ltd were appointed as energy consultants to produce an energy strategy for the scheme at Manor House, Manor Lane, Feltham, London – to support the planning process, demonstrate Building regulations Part L2B compliance and to demonstrate the overall energy strategy associated with driving CO2 emissions reduction against 2010 building regulations via renewable technology.

The Manor House project entailed a Change of use from Health Centre to an Educational Spiritual Centre. Furthermore, the proposed development comprises of a 4 storey building consisting of community centre space and ancillary living accommodation. The site, highlighted in red (see above) extends to 0.56 acres (0.23 hectares) with a frontage to Manor Lane of 56 m (184 ft).This project required Syntegra to conduct a number of assessments, namely:  M&E consultancy, LED report, utilities procurement, energy strategy report, to name a few.

The improvements to structure and services included the following:

1. All external walls to be lined internally to give a U value of 0.35w/m2k i.e. reduced from 1.6 w/m2k.
2. All existing double glazed windows to be re-used.
3. All mechanical ventilation to be kept to an absolute minimum, but where used heat recovery devices to be employed wherever possible.
4. New Condensing boiler(s) to be installed having a minimum efficiency of 89%. (existing boiler efficiency around 60% and includes asbestos gaskets.)
5. All existing piped services to be stripped out and replaced with more a efficient system.
6. The calculations include for Photo Voltaic renewable energy, the exact amount yet to be determined, depending on the structural capability of the existing roof.
7. All lighting to be of the energy efficient type.

Scope included but not limited to:

1)   Energy/M&E/renewable technology strategy

2)  BREEAM pre-assessment (school & synagogue) -Target rating ‘very good’

3)  SUDS strategy

The undertaking of an ACI (Air Conditioning Inspection) is a legal requirement according to article 9 of the Energy Performance Building Directive in England and Wales (EPBD). Air Conditioning Inspections are mandatory for all buildings with installed systems with rated cooling output greater than 12kW. The air conditioning inspection consisted of site inspections and the production of the Air Conditioning Inspection reports, which presents the site inspections findings and the recommendations for improving the system’s energy efficiency in order to save energy and reduce carbon emissions.

The Bath Spa University buildings inspected lie under the packaged cooling and centralized cooling systems assessment since they are air conditioned by a number of VRV systems, single DX split systems and centralized Air Handling Unit (AHU) systems.

Syntegra consulting has managed to identify areas of improving the energy efficiency further of the building’s air conditioning system. Recommendations were made in upgrading AC equipment and control methodology. In addition, Syntegra investigated in improving the AC system’s efficiency and buildings overall energy performance further, by recommending the use of LED lighting. LED lighting is the most energy efficient lighting technology compared to conventional technologies. Furthermore, LED lighting generates minimum heat, which helps reducing a building’s cooling load from lighting. Therefore, LEDs not only reduce the lighting electricity cost, but also the AC (air conditioning) cost of electricity due to reduced heat gains (cooling load). In addition, Syntegra managed to present solutions involving energy/heat recovery systems.

The recommendations given took into account lighting design, investment costs and payback periods. The LED feasibility presented total energy and carbon savings of 66%. In essence, a conversion from fluorescent lamps to LED lamps would generate energy savings of 57,300kWh per year and cabon savings of 24 tonnes per year. The feasibility study clearly shows the savings of LED Vs Fluorescent lights. The feasibility study was concluded with a proposal recommending new LED lamps or LED fitting retrofits, together with detailed investment and installation costs, as well as the payback period estimated at 3.7 years with LEDs Lifetime of 19 years

Syntegra Consulting is an independent energy consultancy and can source products from major LED lighting manufacturers.  The company will specify the optimum light sources for its clients for any specific project.  For more information on the Free LED Feasibility Survey, contact Syntegra Consulting Ltd
