What Are The Benefits of BREEAM?
It's the hope that the BREEAM assessment will help building owners and designers improve their carbon footprint across Potters Bar and make better use of their resources. A BREEAM certification is a way of validating how good a building is in terms of the environmental impact through a globally recognised standard.
It's not unheard of that making a building more environmentally friendly will increase the cost of construction - but BREEAM aims to show that by building this way you will save on operational costs in the future that in turn limit investor costs and makes the property more attractive when reselling.
How Is BREEAM Assessed?
BREEAM's aim is to educate building designers, owners and occupiers throughout Potters Bar about the impact their building has on the local area. To do this, BREEAM gives a rating of Outstanding, Excellent, Very Good, Good or a Pass based on transport, waste, energy, health, water, pollution, materials, management and ecology.
What Is A BREEAM Rating?
The BREEAM ratings for a new, non-domestic building in Potters Bar are:
- Pass: standard good practice (top 75%)
- Good: intermediate good practice (top 50%)
- Very Good: advanced good practice (top 25%)
- Excellent: best practice (top 10%)
- Outstanding: innovator (top 1%)
The maximum score a building can achieve in Potters Bar is 100% from a BREEAM assessment. It used to be that 'Good' was the maximum level that could be achieved, however in 2008 a new 'Outstanding' category was added. The percentage required for each level remained the same despite this.
