2. 1.0 Environmental Conditions for spaces
• External design temps can be found from the use of CIBSE guide A table
A2.4 for winter conditions and A2.6 for summer conditions
• A good table to use for internal design criteria is from CIBSE guide A table
A1.5
3. 2.0 External Service Requirements
• The external services to the building include; water, gas electricity, telecoms.
This may also include renewables like biomass.
• Water / Gas meters need to be accessible to the suppler (i.e. on the site
boundary).
• To work out the loadings the BISRA rule of thumb guide can be used or this
could be done through a full assessment of each metered space.
4. 3.0 Mechanical Selection of system Parameters
To select the types of systems we have to
consider type of systems that will meet the
design brief.
• This may include for heat generation gas
boilers, heat pumps, biomass boilers and ect.
• For heating the space this may include fan
coil units, radiators, heated ducted system with
AHU’s and ect.
• For cooling the building this may include VRF
system, ducted system with AHU, Fan coils with
Chillers and ect
• For Water services there may be Rain water
harvesting and low water use fittings
5. 4.0 Electrical Selection of system Parameters
To select the types of systems we have to
consider type of systems that will meet the
design brief.
• This may include lighting uplighters, Cat 5
louvres, LED.
• Electric supply could be CHP, wind power or
solar panels.
• Where will the switchboards, sockets and
data points be required.
6. 5.0 Electrical Power to the development
• You first need to understand the total electrical load to the development.
• The development will require a full supply from the grid, but
• This could be supplemented by renewables (wind / solar power) and CHP.
7. 6.0 Sustainably & Energy strategy
• The sustainability and energy strategy are likely to utilise Low and zero
carbon generating technology's (LZCGT)
• These include wind turbines, heat pumps, solar thermal panels,
Photovoltaic Panels, Combined heat and Power, fuel cells and biomass /
Biogas boilers.
• These can be used any number on a project, just note cost
8. 7.0 Compliance with Section 6 and 7
• Section 6 deals with the energy consumption of the building, while section
7 deals with the sustainability of the building.
• To comply with section 6 a the building need to be less than a Target
Emission Rate (TER)
• The SBEM calculation will work out the notional building (based on a
number of factors) and then we need to beet the Emissions of that building
by a percentage. (TER)
9. 7.1 Compliance with Section 6 and 7
• Section 7 has sliding scale of compliance levels.
• Bronze – compliance with section 1-6
• Bronze Active – as above plus some form of LZCGT
• Silver – Compliance with section 1-6, with a 28.6% lower TER
• Silver Active – as above plus some form of LZCGT
• Gold – Compliance with section 1-6, with a 64.3% lower TER
• Platinum – Compliance with section 1-6, with a 100% lower TER
• It should be noted there are lot of other clauses, but are for schools
10. 8 Entry points and Service routes plant areas
• Entry points for services will naturally be on the ground or basement floor and
as close to the site boundary as possible
• The entry point will also be determined as to where the service runs in the
street and where the provider can make that connection to the building.
• Main service routes to be thought about are vertical and horizontal.
• Vertical service risers can be located behind staircases and lift shafts
• Horizontal services could be located along corridors
• Main plant areas can be located on the roof on within the basement
11. 9 Plant Space Requirements
• For a rough size of main plant area requirements refer to the BISRA rules of
Thumb. This will give rough weight and plant space requirements
• When determining plant layouts a person requires 2m head height and 0.6m
width to manoeuvre round equipment
• A space of 1m is required from all electrical panels
• Large pumps should be place on the ground
• Any AHU’s / Boiler should be located close to the external walls
• Cold water storage would be wise to locate seperatly from boilers
12. 10Access, security, external lighting, Vertical
transportation and Comms,
• Access – does the building need controlled access through key fobs for
employees / maintenance contractors?
• Security does the building require an alarm system for doors and windows
at night, possibly PIR detectors.
• How much in the way off CCTV is required? Throughout the building or
just in the main corridor spaces
• Where will people require access to at night (required lux level's)? Will the
building be lit at night for planning conditions?
• Where will the telecoms be required? Throughout the office area, also
front desk and plant rooms, ect.
13. 11 Fire Protection Plan
• Do you have a fire partition layout from the Architect? If not assume fire
walls will be between floors, segregating plant rooms and main spaces.
• All items of services passing though will be fire stopped, ie Fire dampers in
ducts and incumbent material round pipe and trays.
• All exit ways will be light signed and emergency lights will be installed to
activate to give a background light level in the event of power cut
• Will the spaces have sprinklers
14. 11 Fire Protection Plan Cont
• Fire detection systems – smoke detectors, heat detectors and fire knock
button.
• Fire alarm – where should sounders be placed / should there be flashing
beacons for people who are hard of hearing
• In the event of a fire what services should be shut down. I.e. vent, lifts,
boilers, ect
