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.

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.

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”
