BIM - What it is
BIM, is an Integrated process built on
coordinated, reliable information about a
project from design through construction
and operation
– Create coordinated, digital
design information and
documentation;
– Predict performance,
appearance, and cost;
– Deliver the project faster, more
economically, and with reduced
environmental impact.

BIM – What it isn’t
– It’s not just 3D CAD
– It’s not just a new technology application
– It’s not next generation, it here and now!
BIM is essentially value creating collaboration through the entire life-
cycle of an asset, underpinned by the creation, collation and
exchange of shared 3D models and intelligent, structured data
attached to them.

There are also workmanship issues…

BIM Maturity
• Level 0
Unmanaged CAD probably 2D, with paper (or
electronic Paper as the most likely data
exchange mechanism.

BIM Maturity
• Level 1
Managed CAD in 2D or 3D format using a
common data environment, and possibly
some standard data structures and formats.

BIM Maturity
• Level 2
Managed CAD in a 3D environment held in
separate discipline “BIM” tools with attached
data. The approach may utilise 4D Programme
data and 5D cost elements.

BIM Maturity
• Level 3
Fully open process and data integration enabled by IFC /
IFD. Managed by a collaborative model server. Could be
regarded as iBIM or integrated BIM potentially employing
concurrent engineering processes.

investment and commitment … while also providing a recognisable
auditable standard to demonstrate our abilities externally.”
“Our next step is to achieve Business Systems certification for the
remainder of our studios and extend our employee capability through
the BRE BIM AP accreditation scheme.”

The measure of our success
BREEAM Aims & Objectives
BREEAM family of schemes aim to:
– Ensure best environmental practice
– Consider a broad range of environmental concerns
– Balanced to ensure quality, safe & healthy environment
– Set standards surpassing those required by regulation
– Challenge the market to provide innovative solutions
– Provide a credible environmental label
– Stimulate demand for sustainability in the built environment

How did it approach energy:
Neighbourhood level:
• 100% green heat and green
power use at the district level
supply of green power and
green heat to the surrounding
neighbourhood;
• decentralised generation , local
distribution – local supply:
matching supply and demand
for heat and power.
Building level:
• follows the criteria were
buildings are designed first to
minimise energy loss –before
the focus shifts to renewable
energy solutions;
• demand for heat reduced
through insulation and air-
tightness
• low-energy housing: K-level
26W/m2K (BAU = K45)
• maximisation of renewable
energy sources;
De Balk van Beel, Leuven, Belgium
LSE's New Students' Centre
• incorporated into the design
include a combined heat and
power unit (CHP) to generate both
heat and electricity, photovoltaic
(PV) panels on the roof;
• The design also facilitates natural
ventilation and cooling;
• An LED screen in the ground floor
foyer displaying dynamic
information relating to the PV,
CHP and integrated water
harvesting systems, and the DEC
rating (after a year of operation).
• A 254m2 PV system that
contributes to reducing of CO2
emissions by 32.3%, when
compared to the building
regulations’ Target Emission Rate
• Extremely efficient boilers and
CHP systems that meet the
energy heating demand whilst
also minimising NOx emissions
(less than 40 mg/KWh).

BREEAM In-Use
• BRE Environmental and Sustainability Standard (BES 5058)
• Designed to provide detailed and meaningful insight into the environmental performance of buildings throughout their entire operational life.
• Providing assessment of:
– the building (Asset Rating),
– the operation of the building (Building Management Rating),
– how Clients are managing their activities within the building (Organisational Rating).
Green buildings will become less
valuable than non-green buildings
Green buildings will become more
valuable than non-green buildings
There will be no change
• Business case beyond
operational cost savings.
• Emerging research shows link
between the financial &
environmental performance of
property assets.
• In order to protect and enhance
value, sustainability
characteristics need to be
continually monitored and
reported consistently.
THE
1,850 employees working there. Le Hive’s name is an acronym from the French for hall of innovation and energy showcase.
The retrofit of the seven-storey building reflects Schneider Electric’s position as an energy management specialist, incorporating comprehensive energy monitoring, and was carried out largely by the company’s own in-house experts.
Driven by research, science &
documented best practice
• BREEAM UK New Construction 2011
scheme
• Covers costs associated with:
• ‘Pass’ to ‘Excellent’ ratings
• Energy and water capital and life cycle
costs, payback and utility savings
• Key contributors
• BRE Global – project managers and
authors
• BRE Trust – funding body
• Sweett Group – provided costing
information, conducted cost studies and
produced cost results
Construction capital & life cycle cost study
– Three case study buildings:
an air-conditioned office
a secondary school
a community healthcare centre
– Base case building established (meets
statutory requirements)
– Range of sustainability measures
identified and applied
– Represented progressively higher levels
of BREEAM ratings
– Factors taken into consideration in
determining costs include:
Location (poor, typical, good)
Range of specification choices/design
decisions
Methodology Overview
Capital costs
– Achieving lower BREEAM ratings
incurs little or no additional cost
– Targeting higher BREEAM ratings
incurs some additional cost but this is
typical less than 2 %
Lifecycle costs
– The study of operational costs shows
that this can be paid back within 2 - 5
years through utility cost savings
Headline Findings

Market feedback
Aviva investors use of BREEAM
“All new acquisitions must have a BREEAM
rating”
“BREEAM is a strong rating tool that helps
sound, responsible property investment”
“Tenants will discard of buildings that don’t
have BREEAM ratings”
