About MECO

As the Middle East is made up exclusively of emerging office markets, the Middle East Council for Offices(MECO) was formed in 2009 to promote better practice in the sector. Despite the rapid growth in most MiddleEast markets, a distinct lack of quality in office accommodation prevails. From design to specification to assetmanagement, MECO is committed to promoting acceptable standard of office space in the region. It does thisthrough an open dialogue of roundtable discussions, forums, seminars and the release of research papers.

MECO promotes the advancement of all facets of the office cycle in the Middle East from design to occupation.A focus on research and creating open dialogue with developers, consultants and occupiers allows MECO todeliver a better understanding of what constitutes a superior working environment.

Introduction

The Middle East office market has matured rapidly in the last decade. There is an increasing demand forbetter quality space from occupiers which has arguably seen office development in this region improve at ahigher rate than anywhere around the globe.

Significant sums of sustained government spending over this past decade has drawn more internationaloccupiers to the Middle East and those who are already here have been making their presence larger. Localorganisations are becoming more exposed to international office standards and are seeking improvedconditions within their own work environment. Ultimately, people like to work and function moreproductively in good quality office space.

Whilst there are good examples of quality office buildings and developments in the Middle East,understandably the volume of this category is still being fulfilled.

This guide aims to quantify what is deemed to be ‘best practice’ within the Middle East region for the officedevelopment lifecycle – from design through construction phases on to property management andoperation. It should be viewed as a starting point – a line in the sand – that will evolve as the market developsfurther. It is designed to represent what the MECO committee and numerous contributors from all stages ofthe development cycle consider as ‘best practice’. In addition to design issues, the guide also takes inconsideration both sustainability and operational issues including health & safety, environment and aspectsassociated with the use, operation and maintenance of the office workplace. Although many of the metrics inthe guide may be deemed to be aspirational targets and standards this can only be positive for the sector tokeep evolving and produce good quality office space.

Using all of the metrics within this guide does not imply a perfect building or development. Building designand specification is a complex jigsaw of integrated factors influenced by parameters such as site constraints,local regulations, cost and programme. It is a holistic process and the metrics within this guide merely providea reference point.

Within this guide, the standards imposed by Government agencies have not been ignored but in some casesthey vary from what has been determined as best practice. Developers and consultants should ensure theycomply with local regulations.

Many international occupiers often have minimum standards of occupation and specification criteria whichthey expect in all their offices. These typically include: CSR (Corporate Social Responsibility) items relating tosustainability and accessibility amongst other things; typical occupational density requirements; powerloadings; lighting levels; building health and safety standards; means of escape; security; etc. The wants andneeds of occupiers are considered as an integral part of creating this guide.

NOTES:Throughout the Specification Guide, all measurement types (i.e. NIA, GIA, etc.) are as defined by the RoyalInstitution of Chartered Surveyors (RICS) Code of Measuring Practice (6th Edition) now incorporating theInternational Property Measurement Standards (IPMS) for Office Buildings (2014).

3 Flexibility

3.1

Occupational

Density

1 person per 8m2 -

12m2 of NIA

Standard office accommodation in the region has a higher

Floor Space Ratio (FSR) than that in more developed

markets. A range of 1 person per 10-14m2 is generally

typical in the Middle East. Future requirements will likely

trend to Western standards of higher densities as

efficiency is given more importance by occupiers.

3.2

Subdivision of

Floors

Yes - Design for

flexibility.

Subdivision should be more flexible than currently seen in

many parts of the region, where often slab-to-slab block

walls predefine units with MEP already designed and built

to suit the subdivision. This practice inhibits flexible

subdivision of floors.

Shell & Core flexibility for sub-division in terms of unit size,

MEP, partitioning, fire, metering should be considered.

Structural Design should be flexible to accommodate

additional vertical riser capacity.

3.3

Capability for in-office kitchen and/or Executive Bathroom

Yes

Base build water and drainage design should incorporatecapacity for occupiers to include these facilities withintheir own office space. Water and waste tap-off pointsshould be readily available near the core or a riser withinthe tenancy.

3.4

Capability for separate entrance for men and women

Yes

Although becoming less of an issue in most Middle Easternmarkets, some occupiers may require flexibility for anefficient way to allow separate entrances. The capabilityfor separate bathroom and kitchen should also beconsidered.

3.5

Prayer Rooms and Ablution in Common areas

Yes

Occupiers may request some form of prayer room in thecommon area irrespective of building size. Common areabathroom on the level of the prayer room should haveablution facility. Consider building location with respect tolocal prayer facilities.

4 Building Accessibility

4.1 Car Space provision1 space for every 45m2

of NIA or better

Proximity to public transport links may influence

this ratio. A lower ratio is more appropriate for

developments where occupiers have less choice

of alternative transport. If there is a mixed-use

component to the development, it may be

possible to structure parking across the uses at

different times of day to achieve a lower parking

ratio.

Adequate provision should be given for visitor

parking. Provide allocated disabled parking bays

in close proximity to building entrances. All car

spaces should be numbered and allocated to

facilitate parking management.

4.2 Alternative TransportDevelopment of a

Travel Plan

Consideration to be given to drop off area, public

transport links, lift share schemes and cycling

provision.

4.3 Universal Access

Refer to UK Building

Regulation 2010 Part

M ‘Access to and use

of buildings’.

MECO encourages the development of an access

statement which identifies which approach to

inclusive design you have adopted, the key issues

of the particular scheme, the sources of advice

and guidance used. At its very simplest an access

statement might record that the intention of the

client, designer or design team was to comply

where appropriate with the guidance given in

the Approved Document M. It might also show

how you wish to depart from the guidance,

either to achieve a better solution or to deal with

the constraints of an existing building.

Part M requires the inclusive provision of ease of accessto and circulation within all buildings, together withrequirements for facilities for disabled people. Much ofthe guidance in the Approved Document M is based onthe British Standard BS 8300:2001 (IncorporatingAmendment No.1) Design of buildings and theirapproaches to meet the needs of disabled people –Code of practice, which is based on ergonometricresearch. Note that the guidance given in ApprovedDocuments only indicates one way of complying withthe requirements and that there may be other, equallygood, ways. This is particularly true when dealing withexisting buildings.

5 Building Envelope

5.1

Solar Heat Gain Coefficient (SHGC or G-Value)

0.25 applicable to all envelope glazing on office levels.

It is the ratio of solar gain (due to direct sunlight) passing through aglass unit to the solar energy which passes through 3mm ClearFloat Glass. It is referred to as an indicator to how the glass isthermally insulating (shading) the interior when there is directsunlight on the panel or window. Ideally, glazing should be selectedto maximise LT with minimum SHGC and best U-Valueperformance. Consider external shading devices as alternative toultra low SHGC. External shading should be simple and easy toclean through the use of either a BMU or rope access.

5.2 RoofsTarget U Value 0.2W/m2K

The importance of the roof U-Value is dependent on its area relative to the entire building envelope. The roof U-Value has greater impact in low rise deep plate buildings than in high rise.

5.3 WallsTarget U Value 0.3W/m2K

This is dependent on proportion of glazing. The overall performance of the envelope needs to be considered rather than any one element in isolation.

5.4

Windows / Transparent cladding

TargetU Value 1.9W/m2K

This is dependent on proportion of glazing. The overall performance of the envelope needs to be considered rather than any one element in isolation.

5.5

Thermal Bridging Awareness

YesConsideration needs to be given to the effects of thermal bridging . Detailing of areas where thermal bridging is a risk is encouraged at design stage to improve construction.

5.6Envelope Air Permeability

Target 5m3/hr/m2

@50Pa

Internationally, 2m3/hr/m2 @50Pa is classed as best practice. In theMiddle East, the practice of air tightness testing is under developedand as such a less stringent target has been set. Refer to CIBSETesting Buildings for Air Leakage and ATTMA Technical Standard 1for further guidance. Requires testing at construction stage whichis still in its infancy in this region. Consider sealed facades.

5.7Window Light Transmittance

Maximise after SHGC & U-Values have been achieved.

Glazing to be selected to maximise LT with minimum solar gainsand best U-Value performance. The importance of LT is dependenton a number of factors including office depth, internal layout, useof external and internal shading devices and use of perimeterdaylight sensors. The balance between natural daylight, glare andsolar heat gain should be assessed on a project by project basis.

MECO BEST PRACTICE GUIDE 2015: V.2.0 10

SOUTHERN ELEVATIONS

EAST/WEST ELEVATIONS

Exposed glazing should be kept to a minimum on southern,

eastern and western elevations to limit peak solar gains.

Northern elevations can afford to have slightly higher proportions

of glazing so long as the insulation properties are good and a

recess or overhang is considered.

Internal blinds are less effective than external shading at reducing

the solar heat gain internally as they allow 75% of the solar

energy into the space. Below are some solutions that can be

applied to different orientations to reduce building cooling load

and allow glazing proportions to be maximized.

Building Envelope Solutions

Where external louvres are used, an access strategy should be developed for cleaning and maintenance purposes.

There are a number of elements that together can help to achieve a successful office lighting solution: it needsto be practical, visually interesting, sustainable and safe. If any of these are missing, it is possible that thelighting will fail to achieve the aim of a well-conceived, comfortable space in which to work and interact andconsequently may not be able to endure time.

It is difficult to stipulate a set of objective criteria that when complied with will create a lighting design that issuitable for any/all office space/s. Some important criteria are outlined in this Guide. It would be incorrectthough to say that by following these, will ensure a successful lighting design. Additionally, all too often it isjust the functional lighting that is initially considered, the entire lit environment should always be well-thought-out. The ideal solution would be to include both a daylight and artificial lighting design professional that,alongside the design team, can assess the design situation and propose the best possible lighting solution fora space.

Soft Landings is the BSRIA-led process designed to assist the construction industry and its clients deliver better buildings.Soft Landings helps to solve the performance gap between design intentions and operational outcomes.

10.3 Building fit-out

Encourage tenants to adopt an environmental methodology such as LEED Interiors or SKA rating.

Ska is an environmental labelling method to evaluate fit-out projects. Ska can be used alongside otherenvironmental assessment methods, it differs to Estidamaand LEED new construction by focusing directly on fit-out.LEED Interiors and Ska only include measures that thedesign team can influence, not the wider context of thesite location, proximity to public transport links etc.

10.4a

Operation

Adopt LEED EBOM

Use LEED EBOM: Existing Buildings to certify the operationsand maintenance of a building project and create a plan forensuring high performance over time. The rating systemcaptures both a building’s physical systems and the waythe building is occupied and operated by its managers.

Ensure the base build can facilitate a WELL Certification

The WELL Building Standard® is an evidence-based systemfor measuring, certifying, and monitoring the performanceof building features that impact health and wellbeing. TheWELL Building Standard® is third-party certified by GreenBusiness Certification Inc. (GBCI). By adopting the .WELLCompliance for core and shell, the base build will be able tofacilitate a certification by future tenants.
