Vanilla The operation of the building is in compliance with

applicable laws, codes and standards.

Deep GreenThe operation of the building has a near-zero

impact on the environment and thereby future

proofs our projects.

It doesn’t end here...

New or retrofi t buildings

rarely perform exactly as

design teams intend from

the fi rst day of occupancy. A

soft landing approach which

includes tenant and landlord

meetings as agreed in the

green MOU ensures project

teams can remain involved

after practical completion

to identify energy wastage

or other problems and help

the occupants gain full

control over the building’s

environmental systems.

In Hollywood House, training

was given to teams from both

the landlord, Prupim, and

the tenant, Skanska, covering

the building systems, design

concepts and operational

principles. They learnt how

to set baselines for energy

use, with progress tracked on

the green building monitor

to educate occupants and

drive behaviour that further

reduces fuel and water

consumption. They also learnt

how to use the information

to fi ne-tune mechanical,

electrical and plumbing

facilities to reach optimal

operational performance.

The project team tracks

consumption trends and

monitors operational

performance against agreed

target metrics. Identifying

anomalies or areas for

improvement, the team can

then take corrective action.

This process of continual

improvement helps ensure

the building realises the full

effi ciency gains that a green

retrofi t promises.

GreenThe operation of the building is beyond compliance,

but not yet at a point where it can be considered to

have a near-zero environmental impact.

Green buildings are becoming acost-effective, sustainable andattractive alternative to the traditionaloffi ce environment.

you can’t affordto not build green.

By maximising both the economic and environmental performance

of a building, green features can reduce costs for energy, water,

operations and maintenance. In addition, an improved working

environment is widely acknowledged to result in a happier, more

productive workforce, attract talent and enhance profi ts.i

Increasingly, it seems,

At Skanska, we absolutely believe in this green ethos, advocating it

to our clients and applying it to our own offi ces. In Woking, a green

retrofi t of our offi ce building – Hollywood House – has embraced

the latest advances in green technology and innovative thinking.

Working within the landlord’s budgets,the result has been to vastly

improve the environmental and economic performance of the

building, while creating an

In these pages, we highlight the benefi ts of some of the green

technologies and approaches used in Hollywood House. Although

we’ve implemented over 40 different green measures, this

represents only a fraction of the vast array of technologies available.

In order to avoid dangerous levels of planetary warming, cuts in greenhouse gas emissionsof 80% or more will be needed by the 2050s. This is just one reason why in a fast-changing world we need to live, work and play in much greener buildings.

It is not, however, only a question of new buildings being greener. Some 80% of the buildings we will have in 2050 are already standing, so it is also very much a matterof improving those already built.

Retrofi tting existing offi ces, homes andfactories is certainly going to be a major part of action for greener living. And this is not only about environmental gains but also an opportunity to seek fi nancial benefi ts and improved comfort.

I have got to know Skanska over the last few years and have been impressed by the level of commitment and expertise that is evident across the company’s operations. This includes a lot of time and effort invested in working out how best to deliver green retrofi t.

The work Skanska has done to improve its own Hollywood House offi ces in Wokinggives a sense of what is possible, and whyembarking on ambitious green retrofi t isa desirable and achievable aim. It alsounderlines how Skanska has developed the skills and know how to deliver in this exciting new market.

I hope what the company has to offer will soon be in even more demand, as others come to see the huge potential gains that can come with green retrofi t.

The Leadership in Energy and EnvironmentalDesign (LEED) Green Building Rating System™is the internationally recognised benchmark for the design, construction and operation of high performance green buildings. LEED gives building owners and operators the tools they need to havean immediate and measurable impact on their buildings’ performance. LEED promotes awhole-building approach to sustainabilityby recognising performance in fi ve keyareas of human and environmentalhealth: sustainable site development,water saving, energy effi ciency,materials selection and indoorenvironmental quality.

LEED explained

When the lease for Hollywood House came up

for renewal in 2010, Skanska’s mechanical, electrical

and ceilings team had a tough decision to make.

Should the team stay in its existing building, which

was dated and expensive to run, or move to a new

location and risk disrupting the lives of employees?

The location of Hollywood House, a 1980s fi ve-storey

building in the heart of Woking, was ideal in terms

of transportation links and access to local amenities,

however, the offi ce itself scored poorly in terms of

energy effi ciency. Skanska’s employees wanted to

work in surroundings that lived up to the company’s

green aspirations. They literally wanted to ‘walk the

talk’.

So, the team decided to approach the landlord,

Prupim, and submit a proposal to refurbish the

building and maximise its energy performance,

reducing energy costs. Working closely with Prupim

on each stage of the design, the team successfully

negotiated the fi rst Green Lease/Memorandum of Understanding (MOU) in the UK.

Taking 32 weeks to complete, the resulting green

retrofi t of Hollywood House propelled the building’s

Energy Performance Certifi cation (EPC) from an

F to a C, excellent for a building of this age. And it

has achieved LEED (Leadership in Energy and

Environmental Design) Platinum certifi cation, giving

the two fl oors Skanska occupies a total of 96 points,

the highest ever score in the UK for an offi ce fi t-out.vii

Sustainable materialsHighly sustainable materials were employed wherever

possible, for example, the kitchen units, furniture and

shelving were made from bamboo, a material favoured

by environmentalists for its rapid growth rate and

durability.

The majority of existing fl oor carpet tiles were recycled

into plastic products, while replacement tiles contained

70% recycled content. The plasterboard for the walls

has a recycled content of 79%.

Breathe easyThe paints, adhesives and sealants

used in the refurbishment all have low

volatile organic compounds (VOC)

content contributing to a more

comfortable offi ce environment for

workers (VOCs are chemicals that

release a toxic smell causing illness).

The vinyl used in kitchen areas contains

5% recycled glass and has a low VOC

content.

The lighting arrangementis 20% more effi cient than the original lighting design and 35% more effi cient than guidelines from the Chartered Institution of Building Services Engineers.

7 Monitoring energy useA comprehensive metering system measures the use of lighting, power, heating, cooling and water around Hollywood House,displaying results on monitors for allemployees to see. The data is used tooptimise the effi ciency of the buildingsservices and environment through themanagement team’s soft landing approach; and to support landlord and tenantmeetings, as agreed under the Green MOU.

6 Solar photovoltaic arrayThe roof features a 20kWh 140m2 solar photovoltaic array. To overcome restricted space and climatic issues the array is heldin place by a purpose-builtsteelwork support frame manufactured at the Skanska Fabrications facility.

Generating up to 15,676kWh per year of electricity for the building, with the option to sell excess electricity to the local Woking energy centre via private wire, this equates to a carbon offset of 8,319kg/CO

2 per year.

The payback period is 13 years.

32% savings on tap2 Off-grid electricity

Slashing carbon emissions byover 32% from grid electricity, Hollywood House has becomethe fi rst commercial building to tap into Woking’s energy centre.

This innovative solutionprovides low-carbon electricity via a combined heat and power plant (CHP).

Tomorrow’sworld1 Green building monitor

Recording the offi ce’s carbonfootprint, a bespoke greenbuilding monitor tracks useof energy, water and gas,comparing current performanceto that before the refurbishment.Displaying information onscreens around the offi ce, the monitor includes a warningindicator that alerts employees when performance drops belowset targets. This educational tool supports the soft land approach and provides accurate detailed data for tenant meetings,as agreed under the GreenMOU driving down energy consumption by an additional 5 - 8%.

12 Reducing water useIn Hollywood House, instant boiling hot and chilled fi lteredwater is available in breakout areas via zip taps. Providingdrinking water on demand, this is a highly effi cient alternativeto traditional kettles and water coolers. Passive infrared (PIR) movement detectors and low water usage devices installed onall taps within the kitchens and bathrooms, as well on the toilets, reduce water consumption by 55% as assessed by LEED(Leadership in Energy and Environmental Design).

In case of a malfunction, an over-arching presence detectionsystem will shut down the water mains where a leak or faultoccurs. And a system of meters, linked to the buildingmanagement system, monitors water use throughout theSkanska offi ces, helping us identify further ways to reduce water consumption.
