An overview of what BREEAM ratings are, why they are valuable and what needs to be considered in order to ensure that CHP schemes maximise their impact on BREEAM ratings.
BREEAM Ratings – a brief summary
"BREEAM is the world's foremost environmental assessment method and rating system for buildings, with 250,000 buildings with certified BREEAM assessment ratings and over a million registered for assessment since it was first launched in 1990."
- Energy: operational energy and carbon dioxide.
- Management: management policy, commissioning, site management and procurement
- Health and wellbeing: indoor and external issues
- Transport: transport-related CO2 and location related factors.
- Water: water consumption and efficiency.
- Materials: embodied impacts of building materials, including lifecycle impacts like embodied carbon dioxide.
- Waste: construction resource efficiency and operational waste management and minimisation.
- Pollution: external air and water pollution.
- Land use: type of site and building footprint.
- Ecology: ecological value, conservation and enhancement of the site.
Proposed CHP schemes for new buildings, as well as retrofit installations for existing buildings, will clearly have a major impact on the first of these factors but may also influence ratings on some of the other factors.
The value of BREEAM ratings
Ensuring that your proposed CHP scheme has the maximum positive impact on your building's BREEAM rating is valuable for 2 main reasons:
- Value/attractiveness of property assets – particularly where your property asset is likely to be sold or rented in the market, a positive BREEAM rating will make it more marketable.
- Reputational – if your organisation ascribes value to its reputation for a sustainable approach, a positive BREEAM rating will demonstrate independent, tangible evidence of this approach.
These areas of added value are, of course, additional to the energy/carbon cost improvements that your scheme will be expected to deliver.
Obtaining a good BREEAM rating
"A BREEAM rating is fast becoming a must for both developers and occupiers looking to gain competitive advantage. Early consideration is vital to ensure a top BREEAM rating is effectively achieved in the most cost efficient manner."
In relation to your proposed CHP scheme it is vital to think carefully about your whole project's impact on the future BREEAM rating, including the design and construction phases, and not to concentrate solely on the energy/carbon cost improvements that your scheme will be expected to deliver.
