HEEPI Better Buildings Programme

July 2004

Dr Richard Jones - Building & Facilities Manager


2/34

First Chemistry Building


3/34


Constructed in 1860

First purpose built Chemistry Laboratory

Chemistry as Separate discipline

4 charcoal fires provided fume extraction


4/34



5/34

Chemistry Research Laboratory


6/34

Chemistry Research Laboratory

First occupied 5thJanuary 2004Contains: Organic, inorganic, biological and

physical and theoretical chemists

CRL is a research building, no undergraduates

Occupants are Part II students, Ph.D students,post-docs and professorial chairs


7/34

A Major Advance

Inorganic Chemistry Building 1860Dyson Perrins Building 1915

Physical & Theoretical Chemistry Building 1941

Significant change in working environment

1stclass services and facilitiesUser feedback very positive


8/34

What has worked well ?


9/34

Atrium


10/34

Atrium Caf

Immense success and highly complimented

Always first point of call on tour

Nothing like this before

Chef Manager probably plays important role butdecision to allocate space taken at start

Dilemma: more laboratories or the open space ?


11/34

A. Open Space

Focal meeting point for occupants

Provides change of environment during working day

Lunch, tea/coffee and meetings without travelling

Has encouraged groups/disciplines to interact

Encourages ownership in the building


12/34

Atrium Environment

Under floor heating in winter

Automatic roof vents and windows in summer

Maintains pleasant warmth in winter but cool

environment without costly air conditioning


13/34

Generic Laboratory Design

One generic laboratory design developed

Should be used for all general research work

Allows high degree of flexibility

Users always adapt to space available

Allows for easier consistent maintenanceBuilding is more impressive, contiguous


14/34

Generic Laboratory


15/34

Specialist Laboratory Design

Always a requirement for specialist

laboratories

Usually central facilities, service, production

Specific heat loads, light levels or air handling

Specialist design in response to equipment notUsers wishes

Tendency to build inflexibility or kingdoms


16/34

Dirty/Clean Philosophy


17/34

Dirty/Clean Area Philosophy

Provides clean areas and routes and dirty

areas and routes

Samples, chemicals, white coats, analytical

services in dirty areas

Meeting, eating, visitors in clean areas


18/34

Open Plan Write Up Areas


19/34

Open Plan Write Up Areas

Despite reservations has worked well

Areas not noisy and are conducive to work

Some rules required No music systems


20/34

Water Consumption

Chemistry traditionally uses a lot of water

Water for cooling and vacuum generation

Each fume hood has vacuubrand pump

Despite water use reduction effluent clean

All chemical waste for specialist disposal


21/34

Building Management

Trend 962 BMS

Head end located in building

Building personnel can interrogate easily

Can tweak settings to provide increased

sophistication


22/34

What could be improved ?


23/34

BMS Temperature Control

Currently maintained at 21oC during day

Building 24/7 but less occupancy at night

Unoccupied temperature at night to 18oC

Saves money/energy in winter through less

heating

But..


24/34

in Summer

Possibility to induce additional cooling overnightCould program BMS to have high set back

temperature during summer

But when do I change temperature settings

Could result in heating overnight


25/34

Temperature Control Required

Range or window requiredHeating and cooling unoccupied at 18oC 24oC

Monitors incoming air and makes decision to

heat or cool


26/34

Air Handling


27/34

Air Handling

Building discharges air equivalent to four

bedroom house every secondThis is air conditioned air, expensive air

Face velocity of fume hood is 0.5ms-1

Air supply into building matches extract required

Quantity of air required to maintain velocitygreater when fume hood open


28/34

Education

Educate Users to close sashes whenever absent,

even 2 minutes

Introduction of on-the-spot fines

Also a safety issue, contains problems


29/34

Firetrace

Heat sensitive tube in top of fume hood

Any sufficient heat source will break tube andrelease CO2

CRL has had one genuine solvent fire to date

Fire extinguished in seconds

Negligible damage, replace Firetrace tube and

cylinder, no ductwork or cabinet damage


30/34

Recycling & Waste Control

CRL produces 12 cubic yards of waste per day

CRL produces 25, 45 gallon drums of solvent

waste per month (collected twice per month)

Segregated recycling requires a lot of space,

plastics, steel, aluminium, paper, glass,

cardboard


31/34

CRL Waste Control Area


32/34

Recycling & Waste Control

CRL uses 140 glass Winchesters per day

All arrive boxed and on pallets

CRL recycles back to suppliers

Suppliers cannot collect every day so need tostock pile with general recycling


33/34

Awaiting Recycling


34/34

SuggestionsInclude open areas, natural light and natural

ventilation in buildings

Use a generic design for laboratories unless

specialist equipment dictates otherwise

Seek an increasing amount of sophistication in

building environmental control

Remember education of Users is significant in the

success of the systems

Dont underestimate the amount of space required

to fulfil recycling activities
