Energy Ratings

BER Chart

Building Energy Rating (BER)

The Building Energy Rating Certificate (BER) is part of the Energy Performance of Buildings EU Directive. The aim of the Directive is to make the energy performance of a building transparent and available to potential purchasers or tenants.

Our services include the Building Energy Rating assessments for both Dwellings and Non Dwellings. Our BER services are especially beneficial when utilised at the Pre-planning stage. We take a value engineering approach, which allows the alternative options for improved energy ratings and Part L Compliance to be budgeted and compared. In many cases this leads to a low cost, passive design solution.

BER Certificates

A building energy rating certificate is issued after the BER has been carried out.

Preliminary BER Certificates can be provided using a Simplified Building Energy Model which gives a quick turnaround assessment at the pre-planning stage. For complex buildings that involve atria, natural ventilation and complex building structures, we use an integrated environmental simulation which allows a much more advanced computer simulation of the building.

In all cases, the Building Energy Rating will be accompanied by a detailed report. The report identifies building improvements and investment options for the client to improve the building performance and reduce running costs.

DEC Certificates

From the 1st January 2009, public bodies occupying buildings over 1,000m2 are required to exhibit a DEC, in a prominent place, clearly visible to the public. The DEC is intended to encourage public authorities to adopt environmentally responsible and efficient use of energy in buildings. The DEC is based on the measured energy use, where the actual energy consumed in the building is compared to a benchmark for similar buildings, and shown on the certificate A1 - G scale in terms of primary energy. There is also a CO2 indicator which shows the CO2 emissions associated with the building's energy consumption. Benchmark or typical buildings have a E1 rating.

LEED Certification

Leadership in Energy & Environmental Design (LEED) is an internationally recognized green building certification system, providing third-party verification that a building was designed and built using strategies intended to improve performance in areas such as energy savings, water efficiency, CO2 emissions reduction, improved indoor environmental quality.

Developed by the U.S. Green Building Council (USGBC), LEED is intended to provide building owners and operators a concise framework for identifying and implementing practical and measurable green building design, construction, operations and maintenance solutions.

Having your building LEED rated demonstrates a company’s desire having an energy efficient and environmentally friendly building. LEED certified buildings often provide healthier work and living environments, which contributes to higher productivity and improved employee health and comfort.


BRE Environmental Assessment Method (BREEAM) is a voluntary measurement rating for green buildings that was established in the UK by the BRE. It is the world's foremost environmental assessment method and rating system for buildings, with 200,000 buildings with certified BREEAM assessment ratings and over a million registered for assessment since it was first launched in 1990.

BREEAM sets the standard for best practice in sustainable building design, construction and operation and has become one of the most comprehensive and widely recognised measures of a building's environmental performance.

A BREEAM assessment uses recognised measures of performance, which are set against established benchmarks, to evaluate a building’s specification, design, construction and use. The measures used represent a broad range of categories and criteria from energy to ecology. They include aspects related to energy and water use, the internal environment (health and well-being), pollution, transport, materials, waste, ecology and management processes.

Benefits of an Environmental Rating System

Environmental rating systems are voluntary but they have extensive benefits including:
  • market recognition for low environmental impact buildings
  • confidence that tried and tested environmental practice is incorporated in the building
  • inspiration to find innovative solutions that minimise the environmental impact
  • a benchmark that is higher than regulation
  • a system to help reduce running costs, improve working and living environments
  • a standard that demonstrates progress towards corporate and organisational environmental objectives
