Part L compliance calculations
Over the year, as Part L has been updated, complying with building emission targets has become more demanding. Using Dynamic Simulation Modelling (DSM) for Part L ensures potential CO2 savings can be realised by getting the full benefit of building geometry, fabric, lighting and HVAC systems going into the design. At Leggo Consulting DSM is used for all buildings from the simplest to the most complex.
Sunlight and daylight analysis;
The BRE Report ‘Site layout planning for daylight and sunlight: a guide to good practice’ is often used to guide decisions by Local Authorities over planning applications. We can provide design advice and reports to confirm that new developments meet planning requirements both for the development itself and the impact it has on neighbouring properties.
Overheating studies (CIBSE Guide A, BB101, TM52 and future climate predictions);
The term ‘overheating’ refers to discomfort to occupants caused by the accumulation of warmth within a building. It is considered to be a growing problem in the UK due to climate change, the urban heat island effect, electronic equipment, and increasing amounts of glazing. We can provide design advice and reports to remediate predicted overheating in schools (BB101), non-domestic buildings (TM52 and CIBSE Guide A), as well as future climate scenarios using weather data produced by Exeter University.
Load calculations for plant sizing;
Space heating and cooling loads for plant sizing using dynamic simulation modelling which captures the dynamic relationship between internal and external environments.

Sustainability/Feasibility Reports and Energy/Carbon Statements for planning
Many planning authorities now require a planning application to include a comprehensive Renewable Energy Feasibility Statement for a development. Due to the lack of a nationwide policy, feasibility studies will vary between Local Authorities. Many Local Authorities will require a reduction in Energy and many will require a reduction in Carbon. Different Local Authorities will also ask for different reductions, some will require a 10% reduction, whereas others may require a 20% reduction or more using renewable energy. We will liaise with the Loca
