Part L2 Analysis for New and Existing Buildings

Our CIBSE registered Low Carbon Consultants provide support to clients by advising upon legislative matters such as Part L2A and Part L2B compliance. This includes using Dynamic Simulation Software to check buildings meet the carbon emissions requirements set by the regulations (criterion 1) and solar gains do not exceed the established limits (criterion 3). 

Energy Performance Certificates (EPC)

Our accredited team of Low Carbon Energy Assessors can produce Energy performance certificates up to level 5 (complex buildings). EPCs are required for buildings on construction, sale or lease.

Air Conditioning Inspections (ACI)

TB+A have a dedicated team of accredited inspectors who are able to undertake energy efficiency audits upon your air conditioning systems and lodge them with the Landmark official register.  Air Conditioning inspections (ACIs) have been a mandatory requirement since January 2011 in compliance with Article 9 of the EPBD that all buildings having an air conditioning system >12kW have a valid inspection report.

The aim of the ACI Report is to outline any areas within the operation of all HVAC equipment that would improve in performance and reduce energy costs. We try to look at the introduction of any no-cost/low-cost initiatives and any capital investment opportunities that may arise.
The survey covers the inspection of air conditioning systems, measuring the performance and power of fans, and associated cooling electrical load, comparing performance with industry standards to identify energy savings whilst maintaining their minimum performance requirements.

Minimum Energy Efficiency Standards (MEES)

The Private Rented Sector Minimum Energy Efficiency Standard (MEES) Regulations were approved in February 2015. These regulations are based on duties set by the Energy Act 2011 and establish the following:

  • From April 2018 it will be unlawful to grant a new lease or renew an existing lease for properties in England and Wales if their Energy Performance Certificate Ratings are F or G.
  • From April 2023 this mandate will apply to all rented property, including where leases are already in place.

We can help you to understand the risks and undertake an analysis of your existing EPC data and building services to determine what improvements, if any, may be needed to improve building efficiency and meet the MEES regulations.
