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

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

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 ?
7/26/2019 CRL HEEPI.ppt
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
7/26/2019 CRL HEEPI.ppt
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
7/26/2019 CRL HEEPI.ppt
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

Generic Laboratory

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

Dirty/Clean Philosophy
7/26/2019 CRL HEEPI.ppt
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

Open Plan Write Up Areas
Despite reservations has worked well
Areas not noisy and are conducive to work
Some rules required No music systems
7/26/2019 CRL HEEPI.ppt

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
7/26/2019 CRL HEEPI.ppt

Building Management
Trend 962 BMS
Head end located in building
Building personnel can interrogate easily
Can tweak settings to provide increased
sophistication

What could be improved ?
7/26/2019 CRL HEEPI.ppt
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..
7/26/2019 CRL HEEPI.ppt
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
7/26/2019 CRL HEEPI.ppt
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
7/26/2019 CRL HEEPI.ppt
26/34
Air Handling
7/26/2019 CRL HEEPI.ppt
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
7/26/2019 CRL HEEPI.ppt
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
7/26/2019 CRL HEEPI.ppt
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
7/26/2019 CRL HEEPI.ppt
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

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
7/26/2019 CRL HEEPI.ppt

Awaiting Recycling

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
