Webinar Instructions

• We will be recording the webinar. Please turn off your audio or video if you do not want to appear on the recording.

• Throughout the webinar you can write your questions in the ‘Chat’. During the Q&A session (14:00-14:30), you may be invited to 'unmute' and ask your question verbally.

• If you would us to ask your question on your behalf, please write it in the Chat and add ‘ask for me’ to the question.

• Please keep your audio muted when not asking a question or taking part in a discussion.

• If you have a technical problem with Zoom, you can write a message to ‘Richard (ASBP)’ on the ‘Chat’ and we’ll try to sort it out.

Plastics in Construction – Dragon’s EcoDen® Pitch Series

Aimed at innovators, start-ups and manufacturers launching new product

ranges, the purpose of the ‘Dragons’ Den’ style event programme is to identify

innovative alternatives to conventional plastic building materials and

packaging.

Events to be held in the autumn with a Grand Final in 2021!

• Single use plastics and packaging – Thursday 17th September

• Building services – Thursday 15th October

• Flooring, finishes & paints – Thursday 19th November

• Building elements (Walls, doors, windows, roofs) – Thursday 17th December

Supported by the ASBP

Plastics in Construction Group

Plastics in Construction – Introductory Q&A Guide

New interactive PDF introductory guide

on ‘Plastics in Construction’.

- Why plastics?

- What are the issues and alternatives?

- What are the drivers?

- Why ASBP and plastics?

- What is being done?

Authored by ASBP and peer-reviewed by

Plastics in Construction Group members.

zLatest predictions

From the start of 2020, the remaining carbon budget is 985 Gt CO2 for limiting warming to 2.0°C with a 66% probability.

The remaining carbon budget is reduced to 395 (235) Gt CO2 if meeting the warming limit of 1.5°C with a 50% (66%) probability is aimed for.

The remaining budget will be used in 5 year and 7 months if emissions don’t drop.

zMechanical, Electrical, Plumbing (MEP)

Mechanical: Heating, Ventilation, Air conditioning

(HVAC)

Electrical: Telecommunication, Power distribution,

Lighting, Security, Fire protection

Plumbing: Domestic hot and cold water, Sanitary,

Drainage, Gas supply, Compressed air supply, Steam

zImpact of MEP

The Carbon Leadership Forum estimated that the upfront impact of MEP systems ranged from 40 to 75 kg CO2e/m2

Components of MEP in this study included:

Mechanical: Equipment and ductwork for Heating, Ventilation, and Air-Conditioning (HVAC) systems*

Electrical: Generators, batteries, electrical service and distribution, wiring devices, and lighting fixtures

Plumbing: Domestic water piping and sanitary sewer piping*

*Excludes refrigerants and plumbing fixtures and fittings

zReplacements

Building Services are often replaced within 10 to 20 years of

installation

This means their impact is much greater over the building

lifetime

The Carbon Leadership Forum estimates that MEP can account

for around 50% of embodied carbon over a 60 year lifetime.

zImpact of MEP

The Swiss estimated that the Embodied Carbon impact of MEP systems for residential buildings over 60 years ranged from 70 to 190 kg CO2e/m2

Components of MEP in this study included:

Electric equipment

Heat generation

Heat distribution and delivery

Ventilation equipment

Water (sanitary) equipment

zPotential Savings in London

1.2 million square metres of office space were being constructed in

London in 2019 – the associated MEP could have up to 93,000

tonnes of upfront carbon (consumption footprint of 8000 UK people)

If this was constructed with best practice embodied carbon MEP

rather than typical, it could at least 25,000 tonnes of Upfront CO2

today, with ongoing savings in replacing MEP into the future
