Why do we need another Eco Rating tool?

Why do we need another Eco Rating tool?

There isn’t a tool that adequately brings together Eco-efficiency assessment & specification of building elements for a circular economy! There is a need for an improved approach for circulareconomy sustainable design & build decisions that fundamentally closes three Gaps

Gaps!

Why do we need another Eco Rating tool?(Cont..)

The three Life-cycle and cradle to cradle problems/gaps in construction & buildings, namely:

Performance Environment impacts Affordability.

NSBM Eco-Efficiency Framework

Cost assessment tool

Virtuous Circle for Continuous Improvement

Inventory of sustainable materials with performance criteria (ideally with EPDs or best substitute) covering:

• Buildability

• Habitability

• Ecological Impact and the Environment (2Es)

• Durability and whole-life costing including maintenance, final disposal plus potential for re-use of construction materials – DfD..

• Prevention of toxicity and hazardous chemicals in construction and use.

Material database

An intelligent model providing insight to plan, design, construct (and deconstruct ?), manage buildings and infrastructure.

Optimise engineering solutions detecting clashes Improves quality of communication and information to make critical

decisions about design and interaction with partners Improves the quality of the services delivered Reduce the costs at every stage of the lifecycle of the building Provide greater clarity for all stakeholders across the project

Database for materials and products EN 15804 – Environmental Product Declarations

Product level data feeds into element level framework i.e. convert x kg bricks + y kg cement = 1 m2 brick wall …etc

Building element level framework feeds into building level framework i.e. x m2 brick walls + y m2 windows….etc

SummaryA tool that provides improved pathways to:

• an Eco-efficient standard which is more than just the carbon equivalent (CO2e) assessments of buildings in operation or embodied energy.

• integration of key qualitative and quantitative considerations into a single LIFE-CYCLE assessment score which closes the affordability, performance and environment gaps including those in buildability, habitability and ecological fit.

• circular economy methods for better buildings to avoid unacceptable impacts on people, communities and the planet.
