Paragraph 55 Schemes – Sustainability Support

News Bulletin EE-02


Energy Evaluation consultants have many years’ experience in delivering high specification sustainable solutions for residential developments. Furthermore as part of the DLP Consultancy family we have well established strong connections with in-house Planning Consultants, Architects and Transport Consultants to support Paragraph 55 schemes from initiation through the planning process to final delivery.

Energy Evaluation can assist in producing schemes that are truly innovative. Schemes that maximise the use of natural resources whilst reducing the impact on the environment and finite fuels. Energy Evaluation proposals are formulated to enable clients’ designs to attain low or zero carbon targets or perhaps to achieve Passivhaus standards.


Energy Evaluation solutions are based around an ethos of Fabric Energy Efficiency First. This design ethos makes the most of natural resources before considering the use of alternative LZC Technologies.

Our input generally includes the development of a 3D model to aid in the review of:

  • Orientation – Passive Solar Design: maximising beneficial solar gain during the heating season, whilst reducing the risk of overheating during the summer.
  • Shading Features – brize-soleil, overhangs and planting.
  • Fabric – Review of use of high performance or innovative materials, thermal bridging & air tightness.
  • Glazing – Maximising natural light, and controlling solar gain.

With a combination of Dynamic Simulation Models (e.g. EDSL Tas) and SAP calculations we can assess the performance of the proposed dwelling in terms of energy and CO2 emissions. The performance of different heating and ventilation solutions can be appraised including:

  • Standard heating systems (gas-fired)
  • Biomass boilers
  • Air Source / Ground Source Heat Pumps
  • Mechanical Ventilation and Heat Recovery.
  • Summertime overheating risk (Part L1a Criterion 3 or more detailed CIBSE TM 59 (2017)

Energy Evaluation can provide a costed Feasibility Assessment of suitable technology including:

  • PV
  • Solar Hot Water
  • Heat Pumps
  • Wind Turbines
  • Micro CHP
  • District Heating

Given the implications of Paragraph 55 requirements we strongly recommend that developers and their agents get in touch with Energy Evaluation to discuss how best to approach any scheme. Energy Evaluation has a full suite of tools to aid in the full consideration of energy efficiency, water efficiency and climate change adaption. In addition our consultants are qualified to prepare calculations and EPC/ SAP certification for submission to Building Control.
