- • Brian Murphy will provide:
- • A glimpse into the world of EE, EC, LCA, BIM, D&DT, Validation of manufacturers information
- • Offer some tools to help steer a safe root between sustainability and liability
- • Suggest new career opportunities

OE/C > EE & EC
- • During the Sustainability Revolution we will progress towards:
- • low energy demand buildings
- • shift our focus towards
- • embodied energy & embodied carbon – building fabric
– services
- • If BRE and BREEAM ever catch up
100% Thermal Insulation: Energy in use in building
Materials & Thermal Insulation: Embodied Energy Embodied Carbon (Carbon positive) 100%
0% Now Zero carbon Homes by 2016!
-5 to -20%
Materials & Thermal Insulation: (Carbon negative)
UK Perspective
- • bre’s BREEAM Environmental Assessment Method
- – Non-domestic, voluntary, going global, fail>pass>excellent>outstanding>green
- – Tick box exercise, found wanting in many areas and supporting tools
- – Not based on low operational energy buildings so biased (weightings) as a result
- – 5-7% of credits down to materials (weighting must change & % increase)
- • Code for Sustainable Homes (created by bre based on EcoHomes/BREEAM)
- – Government (DCLG) requirement for funded housing slow development to higher standards
- – Delayed, progressively adopted in private housing development
- – No requirement in private houses and self build (many living a >3++++ planet lifestyle + eco bling)
- • bre’s Green Guide to Specification
- – Backed by Construction Products Association
- • Predominantly conventional materials manufacturers
- • predominantly big or medium sized enterprises
- • Or highly automated low labour force with big turnover
- – Predominantly violet materials, but claims a level playing field
- – Generic LCA, whole elements, conventional construction
- – Backed by Construction Products Association
- • bre’s GreenBookLive
- – Environmental Profiles = EPD,
- – products, violet ingredients, carpets, PVC, bitumen
- – EPD being worn as a green badge when it is not a green badge
- • The UK at least needs an OR EQUIVALENT with a level paying field and green materials included
- • bre are breaking into the EU & Global market with BREEAM
- • EU and the world needs an OR EQUIVALENT
Carbon in buildings
- • Sequestered Carbon in biobased materials
- • Embodied Carbon & Energy in materials
- • Embodied Carbon in embodied water in materials
- • Embodied Carbon in transport of materials
- • Embodied Carbon in transport of people
- • Embodied Carbon in construction
- • Carbon load of mains water in use
- • Carbon in Energy & Fuel & Heat
- • Operational Carbon in operation & maintenance
Status Quo
- • Our industry
- • Self serving
- • Profit focused
- • Compromise happy
- • Building is a means to an end
- • Competent building is optional
- • Competent Appropriate Environmental Construction is unlikely
BIM & D&DT
- • Government procurement via Building Information
Modelling (BIM)
- • we have the tools to draw and measure/quantify
– but where is the Information & Modelling?
- • BIM libraries are appearing:
– full of dumb models
- • Design & Decision Tools are needed to:
– analyse, compare, choose appropriate products, materials – make changes to our specification habits.
- • Everybody needs to become involved in driving change:
– designer, specifier, cost controllers, value engineers, manufacturer, installer, facilities manager.
Architects
- • Many Architects don’t fully understand
– physics of buildings and science of materials,
- • Focus on philosophy, poetry, art and BS
- • Quite often short on knowledge
- • Rarely brief the engineers in sustainable approaches to be adopted
- • Engineers with calculations can run rings round them
Engineers
- • Engineers are focused on the numbers of structural and services engineering
- • whilst Environmental Assessment Method (EAM) are on efficiency drives;
– Tick box exercises
- • Engineers need better guidance on the environmental opportunities. © NGS 2013 Services LCA EE EC BIM.pptx
Services Engineers
- • Services Engineers read the journals about novel approaches to:
– low energy lighting, lighting controls,
– sustainable drainage,
– water saving appliances and valves,
– smart meters and smart or intelligent buildings,
- • but we still see many dumb solutions born out of:
- – some knowledge applied badly,
- – fear of health and safety,
- – resulting in wasteful practices and higher energy consumption
© NGS 2013 Services LCA EE EC BIM.pptx
Specifiers
• Standard specifications are the norm,
– reliant upon the drawing annotation or schedules to point at the specification clauses relevant to the project.
- Standard specification quite often:
- – permit the use of recycled aggregates or OPC replacement
- – but do not require their use,
- – unless the Engineer is proactive in requesting them,
- Industry norm will be adopted for familiarity, simplicity and piece of mind.

QS & Cost controllers
- • compromise between what we design and what we build with: – cost cutting,
– value engineering (Another fiction)
• (looking at more than one item at a time and finding cheaper overall solutions)
• Usually cost cutting in disguise
- • with low initial cost as the primary criteria for success
- • CAPEX v OPEX
- • TOTEX no where to be seen
Contractors • substitutions
– (often replacing a good product with a worse one or a different performing product),
- surreptitious or otherwise,
– with profit margin as the primary criteria for success.
© NGS 2013 Services LCA EE EC BIM.pptx
Constructors
- • Further degradation of ambitions occurs on site through lack of communication from the design team,
- • lack of understanding by site agents and managers leading to poor substitutions,
- • poor supervision, lack of care or lack of knowledge of new systems or methods
- • leading to misguided ambition or poor workmanship.
Sustainability Revolution • Aiming for:
- Competent Appropriate Environmental Construction, it is possible
- Falling a long way short mostly
• Even the dark greens are not always successful
- Thermal bridging permitted by mixing component size to reduce waste change k value of materials in cavity walls

Carbon Dioxide
- • A gas
- • 1 part Carbon and 2 parts Oxygen
- • Abbreviated CO2
- • An important part of the Earth’s Atmosphere
– Not enough and its too cold,
– too much and its too hot

Carbon Dioxide
- • Can be liquid at cold temperature
- • Recently used as a blowing agent in foamed plastics
- • Has been used to fill double glazed sealed units
- • Used in fire extinguishing? © GreenSpec 2008-13 BrianMurphy

Renewable Carbon
- • Carbon in the form of cellulose fibre as grown by plants and trees is renewable over a much shorter period
- • Some is naturally fast growing
- • Some slower and artificially fast grown
in plantations
- • Uses include: Food, Oils, Biomass fuel, Bio-fuels, material for cloths, utensils, boats, construction materials
Renewable Carbon Materials • Materials using plant and tree based cellulose
• Trees: 40-100 years >
– Wood many applications
- • Plantation thinnings: much sooner >
– small section and composite timber products, timber fibre and flour
- • Wood fibre:
– Thermal and acoustic insulation, underlayment isolation, soft batts and rigid boards
Rapidly Renewable Carbon Materials
- • Plants: 1 growing season: – E.g. cellulose fibre
– E.g. Hemp shiv
- • Bamboo: 1 growing season >
– animal food
– Flooring, linings, boards, etc. – Liquid store, pipes, scaffolding
- • Oils and resins:
– 1 growing season > Linseed oil,
– Linoleum flooring – Paints, oils
Renewable carbon materials v Non-renewable carbon materials
- • Plant based materials with properties of plastics
- • Potato starch made into equivalent of expanded polystyrene
– At end of use + water > reverts to starch
- • Bio-plastics are being developed using plant based material and plant extract resins
– With the properties of plastics
- • Foamed plastics in particular
- • Plant based resins in place of synthetic resins
– used to make carpet
- Resin and cellulose – furniture
Carbon Sequestration
- • The naturally occurring or deliberate removal of carbon from the atmosphere
- • The storage of carbon in materials or a store or a sink where it will remain.
- • Types of sequestration include:
- – ‘geological’ where CO2 is captured and buried
underground or under ocean e.g. in porous stone
-
- – ‘biological’ where CO2 is absorbed during the growth of plants and trees.
- – ‘Oceanic’ where CO2 is absorbed by the surface of the oceans
- – ‘Soil’ where CO2 is absorbed by top soil
Carbon Sequestration in Construction
- • usually refers to building products derived from plant materials
– such as wood and hemp,
- • where CO2 is absorbed as part of the
growing process.
- • The carbon remains ‘locked’ in the material for the lifetime of the building
– And potentially beyond end of first life.
– BRE Green Guide assumes its burned or
landfilled
– But we have 1⁄2W2L not long until 0W2L
Carbon Trading (a kind of Fiction)
- • Kyoto Summit’s Protocol called for Carbon reductions by all nations
- • USA and a few others refused to sign up if it meant this might affect their business communities profitability (and profligacy)
- • A last minute suggestion to try to get the USA to sign up was to invent a way for the developed countries to do nothing and pay another country for its share of unused ‘carbon credits’
Carbon Offsetting
- • A kind of Fiction
- • Ask an abstaining couple to abstain from sex
- • So you can have affairs when you want
- • Everything is in balance
© NGS 2013 Services LCA EE EC BIM.pptx
Embodied
- • A kind of Fiction
- • Energy or Carbon or Water
- • Conceptually Embodied in material
- • Not embedded
- • But left in the factory or released to the atmosphere or discharged into the drain or disposed in landfill
© NGS 2013 Services LCA EE EC BIM.pptx
Embodied Energy
- • All the energy required and used to grow, harvest, extract, manufacture, refine, process, package, transport, install of a particular product or building material.
- • What about:
– maintaining and disposing of it?
– embodied energy of the labour force
- that made it, stock it & travel to site to install it?
Embodied Carbon
- Conceptually, Carbon ‘embodied’ in the material but not ‘embedded’ (no longer or never present in the material)
- Usually the totalling up of the carbon
- – used to create a material or product
- – Or released in the manufacturing
- – Includes the carbon from fossil based fuels used in the manufacturing processes and transporting
Embodied Energy v Embodied Carbon
- • Don’t mix them up
- • They are not the same thing
- • Many materials use energy to manufacturer
– Depending on the fuel choice
- different levels of carbon outputs
• Some materials release Carbon/CO2
– To the atmosphere – Plastics
– Cement
- • Steels are high embodied energy
- • Plastics are high embodied carbon
- • Cement is high embodied energy and carbon
Embodied v Embedded Carbon • Embodied is understood
- Embedded:
– Unhelpful term too close to Embodied
– Related to Sequestered Carbon? – But ……proposed definition…..
© GreenSpec 2008-13 BrianMurphy
Embedded Carbon?
- • Plastics are made from hydro-carbons
and still contain them
- • The have ‘embedded’ carbon
- • They can be ‘un- or re-processed’ back to hydro-carbons
- • In time landfills will be mined to reclaim plastics to turn back into hydro-carbons
- • to make fuel or other plastics
Carbon Sequestration
- • Growing plants, bamboo, wood, etc.
- • Turns carbon dioxide from atmosphere into renewable carbon cellulose fibre
– Waste product is oxygen
- • Stores carbon dioxide in wood fibre
- • Timber in construction stores CO2
- • For the life of the building
Renewable Carbon Sequestration
- • Carbon8Systems
- • Carbon Dioxide, Water and particles
- • Combine to grow calcium carbonate ‘stones’ around the particles
- • Stones that can be aggregates
- • Grow tiles around particles
© GreenSpec 2008-13 BrianMurphy
Low Carbon alternatives • OPC Ordinary Portland Cement
- Replace with OPC substitutes
– GGBS Ground Granulated Blast Furnace Slag Cement (from steel production)
- – Or 65% GGBS blended with 35% OPC
- – PFA Pulverised Fuel (High Carbon Coal) Ash Cement
- OPC replaced partially or completely
- – with Lime
- – Lower cooking temperature
- – Carbon sequestered during construction and during building life
Carbon negative, positive & neutral
- • Grow Trees
– Carbon sequestration from atmosphere
– Carbon negative C-ve
- • Convert to wood or paper
- • Burn wood or paper
– Release carbon to atmosphere
– Carbon positive C+ve
- • Net result: Carbon neutral C+=-
- • But there is a little energy and possible carbon in converting the tree to wood or paper
– not quite Carbon neutral a bit Carbon positive C+ve
Carbon Negative
- • Hemp-lime construction
- • Uses hemp shiv as an aggregate C-ve
- • Uses lime as a binder C+ve
- • To make a material like concrete C-ve
- • But many other positive properties
- • But add cement for fast set C+ve
- • Add aluminium oxide to react with cement to foam like aerated concrete E+ve
- • But still C-ve
Carbon Positive • Often used confusingly
- meaning carbon negative with a ‘positive’ swing
© GreenSpec 2008-13 BrianMurphy
Carbon Neutral
- • Conceptually, a state whereby the CO2 generated by a process is exactly balanced by the amount of CO2 either offset or sequestered by the process.
- • A carbon neutral building is one that either uses no fuel that generates CO2 or where its consumption of CO2-generating fuel is equally balanced by exported renewable energy.
- • The definition continues to be debated as to the extent of direct / indirect CO2 that is included in the equation
- • E.g. CO2 generated in the construction of the building.
© GreenSpec 2008-13 BrianMurphy
Carbon Load
- • Associated with water supply:
- – Water is cleaned with chemicals and energy
- – Water is pumped with energy into water towers to deliver by gravity
- • A water sector is a major
– User of energy
- • The energy sector is a major
- – user of water
- – waster of energy and heat (75% of input)
- – Power stations use steam turbines
- – Turbines are fed with water turned to steam
- – The steam is cooled in cooling towers
- – Steam escapes and some water is recycled
- • Its time this was sorted out, where is CH&P,
– whichever fuel they choose
Low Carbon Building (LCB): (In use)
- • LCBs are buildings which are specifically engineered with Carbon Dioxide reduction in mind (a major Greenhouse Gas (GHG) with Climate change potential).
- • So by definition, a LCB is a building which emits significantly less Carbon Dioxide than regular buildings.
- • There is at the moment no emissions threshold under which a building would qualify as a LCB.
- • But to be genuinely Carbon or CO2 neutral, a LCB would have to achieve at least 80% Caron or CO2 reduction compared to traditional buildings.
Achieving 80% Carbon Reduction is easy!

Cradle-to-*
- • Life Cycle Analysis (LCA) is often broken down into phases of lesser ambition.
- • Cradle-to-cradle
– Where recyclable / reusable products are the subject
- • Cradle-to-grave
– For non-recyclable materials that are destined to be disposed of
- • Cradle-to-gate
– production from extraction of raw material and factory production
- • Cradle-to-site
– extraction, factory production and delivery to site
– though these LCAs are useful and more common – they tend not to tell the whole story
LCA for Transport
• We need transport LCA calculators too
- For all parts of the journey
– From source by Land to coast or airport
– port to port by sea
– Airport to airport by aeroplane (fantasy) – Coast to site by land
– Trains or trucks?
– What size truck?
– Via logistics centres different size trucks
- not just by sea (fiction)
Carbon sequestration in LCAs
- • BRE Green Guide argue that the carbon sequestered by
plant or tree
- • stored in construction materials for life of building
- • Will be released when the materials are landfilled or burned (not always the case)
- • However Landfill is no longer seen as end of life option so BRE cannot assume this any more
- • Designers have a long way to go to habitually design for deconstruction
- • But MMC is easy to assemble, dismantle and reassemble
– So lets make things well, durable & robust so they can be reused
Carbon sequestration in LCAs
- • BRE argue that materials will be lost to
landfill
- • but we argue they may also be suitable for composting so they still retain Carbon
- • Some plant based thermal insulation materials are robust
- • Can be used and reused
Environmental profile
- • The output of an environmental profiling process
- • Profiling can be of a generic nature using general industry data or it can be of a proprietary nature using product- specific data
- • for example as part of the BRE’s ‘Environmental Profiles Certification Scheme’.
- • Generic profiles (based on whole sector data) form the basis of the BRE’s ‘Green Guide to Specification’.
– A fiction based on fact
- • Product Profiles (based one manufacturer’s product) form
the basis for BRE’s ‘Green Book Live’
- • Occasionally Product profiles are used by BRE in Green Guide creating false impressions of green materials
Environmental profiling
- • The ‘identifying and assessing the environmental effects associated with building materials’ (BRE)
- • usually using a standardised methodology
- • The UK profiling market is dominated by the BRE, but other methodologies are currently being developed
- • for example CAP’EM project.
CAP’EM project
- • An EU Interreg funded project, currently underway,
- • to develop a harmonized assessment procedure for building materials based using a simplified LCA-based methodology.

Carbon-Free? • Renewable Energy sources
– Carbon-free energy:
• Solar PV, Solar Thermal, wind, hydro, wave, tidal, current,
– Carbon-neutral energy: Biomass
- Take care to distinguish between renewable energy and energy efficient
– Energy Efficient
• Heat Pump: air, water ground source
- Must use carbon-free energy-in
• To get carbon-free more energy-out
Low impact services
- All natural or passive
- Natural Daylight Sunlight and Moonlight
- Passive or Active ventilation no AC – Fabric ventilation systems
- Passive stack effect buoyancy
- Aquifer delivering freshwater to surface
- Gravity & syphonic drainage – Wooden rainwater goods
- Metals and plastics: better choices than BAU
ME&P
- • Made of plastics, metals, circuit boards, etc. services
- • will probably have the biggest impacts despite smaller volumes.
- • Plastics: High Embodied Carbon and Energy
- • Metals: High Embodied Energy (& Carbon from Fuel)
- • Circuit boards: Metals Plastics Chemicals
- RoHS & REACH & WEEE Regs.
- I said probably, we will only find out when we start to quantify it all.
BIM
• Government Procurement ambitions
– Avoid Errors
– Save Money 20-25% anticipated
- On top of Egan 10% year on year?
– Reduce Government Procurement Costs
– Joined up thinking & doing:
- Design Build Operate

Joined up thinking
- • Needs joined up design teams
- • Needs joined up building models
- – Clash detection
- – Artificial Intelligence
- – No stretching or snap
- – Coordination between disciplines
- – Coordination between services teams
- • Ideally no iteration (a fiction)
- – Service routes worked out accurately
- – Ideally designed services (can you do it any more?)
- not performance specification
- • Needs joined up communication
- • Needs joined up classification

NGS ECHO
- • Confirmation of Manufacturer’s Self-declaration
- • ISO 14021
- • Claims must be based on evidence – Evidence held available for scrutiny
- • It must be transparent
– If its commercial in confidence its not permitted
- • It must be explicit and not ambiguous
Declarations
- • NGS DoC Declaration of Conformity based on ISO
- • NGS DoEM Declaration of Excluded Materials
- • NGS DoRR Declaration of REACH Requirements

PVC
- I thought PVC was PVC (fiction) • But its blended to order
• REACH regulations (Facts)
• SIN List Substitute it Now - SVHC Substances of Very High Concern • Maximum 0.1% or must inform customers • Plasticisers: (Phthalates) up to 30%
• PVC must change or it will disappear
PVC skirting
- • Adhesive failures
- • Polymer migration from high plasticisers coving into adhesive
- • Coved Skirting shrinking – No longer fits
– Gap created
– Place for Bacteria
- • Adhesive fails
– No longer adheres
– Cannot re-adhere
- • PFI hospitals and schools
- • Temporary loss of rooms & corridors to replace skirtings
Careers
- • Re Classification of MEP Specifications
– To Uniclass for BIM or wait for NBS Engineering
- • Project Specifications
– Pro-actively Green rather than optional
- • B Information M
– Information gathering, collating and dissemination
- • B I Modeling
– 3D CAD BIM ready models with Information added
- • D&DT APPS
- – GURUs who understand the Principles, Properties, Materials, Science
- – Develop the APPS that bring the information together
