Energy Efficiency

At Ridings, we use a variety of simulation software such as IES VE and Hevacomp. This allows us to convert extensive building performance data into a clear and concise format for the client.
Our engineering and energy specialists provide in depth assessments and simulations, covering a range of regulations such as Part L, TM52, EPC, SAP’s and BB101. The Dynamic Simulation Modelling we perform allows for early consideration of energy and carbon performance and gives clarification in concept design and architectural proposals.

Ridings have employees accredited through Elmhurst, to produce both L2 calculations and Energy Performance Certificates. We are flexible and can propose the results of these calculations in several different formats, such as 3D models, graphically or in a comprehensive report.

BB101 provides information on regulations, standards and guidance on ventilation, thermal comfort and indoor air quality for school buildings.

This document is used to inform our designs for school ventilation and heating systems to ensure that comfort conditions are achieved for the students, and the energy usage and carbon footprints for the school are met.


Overheating has become a serious challenge for building designers. The need to reduce energy consumption whilst dealing with global climate change and increasingly demanding comfort expectations has reduced the options available for building comfortable, low-energy buildings.

At Ridings, we excel in generating energy analysis and performance models that illustrate potential engineering solutions to address overheating within the building and satisfy the requirements of TM52.


At Ridings, we have employees accredited through both BRE and CIBSE to produce calculations in line with the latest issues of building regulations L2.

We use the SBEM (Simplified Building Energy Modelling) calculation engine as part of the methodology of calculating the energy performance of buildings approved by the Secretary of State for the purposes of Part L.

Our ability to assess and calculate the energy performance of a building at the pre-construction phase as well as at the design and as built stage allows us to comprehensively analyse the performances of the building at every stage of design.

Part L

Energy Performance Certificates are a statement of how energy efficient a building is. The EPC shows the building energy rating on a scale of A to G with A being the most efficient.

The EPC is a requirement for dwellings and the sale, rent or construction of buildings other than dwellings with a floor area greater than 50m².

The EPC Certificate is a reflection of the energy consumed and takes into consideration of all aspects of the building design affecting energy usage. The energy usage parameters are input into a software program which performs the calculation of energy efficiency.

EPC – Energy Performance Certificate

The Standard Assessment Procedure (SAP) is the methodology used by the Government to assess and compare the energy and environmental performance of dwellings. Its purpose is to provide accurate and reliable assessments of dwelling energy performances.

At Ridings, we use the latest government approved SAP software to assess the energy performance of all new dwellings on the residential schemes we work on.
