Chemistry Research Laboratory

1
Chemistry Research Laboratory

• HEEPI Better Buildings Programme
• July 2004
• Dr Richard Jones - Building Facilities Manager

2
First Chemistry Building
3
First Chemistry Building

• Constructed in 1860
• First purpose built Chemistry Laboratory
• Chemistry as Separate discipline
• 4 charcoal fires provided fume extraction

Chemistry Research Laboratory
6
Chemistry Research Laboratory

• First occupied 5th January 2004
• Contains 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
A Major Advance

• Inorganic Chemistry Building 1860
• Dyson Perrins Building 1915
• Physical Theoretical Chemistry Building 1941
• Significant change in working environment
• 1st class services and facilities
• User feedback very positive

8
What has worked well
9
Atrium
10
Atrium Café

• Immense success and highly complimented
• Always first point of call on tour
• Nothing like this before
• Chef Manager probably plays important role but
  decision to allocate space taken at start
• Dilemma more laboratories or the open space

11
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
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
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 maintenance
• Building is more impressive contiguous

14
Generic Laboratory
15
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 not
  Users wishes
• Tendency to build inflexibility or kingdoms

16
Dirty/Clean Philosophy
17
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
Open Plan Write Up Areas
19
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
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
Building Management

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

22
What could be improved
23
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
in Summer

• Possibility to induce additional cooling
  overnight
• Could program BMS to have high set back
  temperature during summer
• But when do I change temperature settings
• Could result in heating overnight

25
Temperature Control Required

• Range or window required
• Heating and cooling unoccupied at 18oC 24oC
• Monitors incoming air and makes decision to heat
  or cool

26
Air Handling
27
Air Handling

• Building discharges air equivalent to four
  bedroom house every second
• This 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 velocity
  greater when fume hood open

28
Education

• Educate Users to close sashes whenever absent
  even 2 minutes
• Introduction of on-the-spot fines
• Also a safety issue contains problems

29
Firetrace

• Heat sensitive tube in top of fume hood
• Any sufficient heat source will break tube and
  release 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
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
CRL Waste Control Area
32
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 to
  stock pile with general recycling

33
Awaiting Recycling
34
Suggestions

• Include 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
