Notes:

*** GENERAL ***

This model represents a tower block flat at the West Whitlawburn Housing Cooperative (WWHC) in Cambuslang.
It is a generic model for the 432 tower block flats (6 towers, 12 floors/tower, 6 flats/floor) at the site.
{11/03/2018}

The general layout of the flat was determined from a floorplan produced by contractors and which is given in
/doc/Tower_Floor_Plan.pdf. Although the proportions of the flat came from this architects drawing, the scale 
of the drawing is unclear and so the specific dimensions of the flat must be verified on site. {11/03/2018}

The model comprises a fully defined thermal building with an associated air flow network for infiltration and
ventilation. {11/03/2018}


*** GEOMETRY ***

The flats are each comprised of several living areas: living room, kitchen, bathroom, two bedrooms, hall and 
a solarium (formed by enclosing a balcony during a cladding refurbishment). {11/03/2018}

The geometry of these living spaces are identical across all the flats (a negligible number have had further
modifications i.e. the splitting of rooms etc.) however the arrangement of the rooms of each flat in a floor
are different. {11/03/2018}

The thermal zones in the model are named as follows:

	Living_#   : Living room in Flat #
	Solarium_# : Solarium in Flat #
	Kitchen_#  : Kitchen in Flat #
	Hall_# 	   : Hall in Flat # 
	Bathroom_# : Bathroom in Flat #
	Bedroom1_# : Bedroom 1 in Flat #
	Bedroom2_# : Bedroom 2 in Flat #
{11/03/2018}

The surfaces forming these zones are according to the following 12-character, quad-designation:

		abc-EfgHij_#
Where:
	
	(1)			(2)				(3)				(4)
	abc = type of surf	Efg = Zone containing surf	Hij = Zone adjoining surf	# = Flat no.

	wal = wall		Hll = Hall			~ As designator (2) ~		A number 0-9 
	flr = floor		Bd1 = Bedroom 1							defining the  
	cei = ceiling		Bd2 = Bedroom 2							flat number in
	wdw = window		Bth = Bathroom							the model.
	dor = door		Liv = Living room
	glz = other glazing	Sol = Solarium
	ext = extractor		Kit = Kitchen
				Out = Outside (building)
				FL# = Adjacent flat*
				LbN = Communal lobby North
			       [LbS = Communal lobby South]
			       [Lnd = Central tower landing]
			       [Ref = Communal refuse room]			
			       [Vd1 = Communal void on floor]
			       [Vd2 = Communal void on floor]
				RGT = "right" **
				LFT = "left" **
{11/03/2018}

* The numbering in FL# (adjacent flat) is arbitrary due to multiple surfaces in the kitchen overlapping the same
  adjacent flat. {11/03/2018}
** RGH and LFT are designators to be used when multiple surfaces (of the same type) in a zone adjoin the same 
   thermal zone. These designators refer to the location of the surface from a viewer walking into the main
   entrance of that zone. In some cases, a lower case zone identifier can be used i.e. hij not Hij.
   {11/03/2018}
[] These designators are not currently used but are included for future whole floor models. {11/03/2018}


*** CONSTRUCTIONS ***

Standard esp-r constructions are used within the model. Information has been gathered from managers at WWHC and
from the floor plan in /doc/Tower_Floor_Plan.pdf to inform this. {11/03/2018}

The following constructions are used:

	Brk_blk_1980	: for internal structural walls (presumed to be predominantly concrete)
	intern_wall	: for internal non-structural walls
	int_doors	: for all doors within the flat
	extern_wall	: for all external walls with cladding installed
	dbl_glz		: for all external windows
	internal_glaz	: for glazing between living room and solarium
	cpt_cel2flr	: for all ceilings
	cpt_flr2cel	: for all floors

{11/03/2018}

! Note: These are provisional constructions and are used more as placeholders than true representations of the	!
! buildings actual current fabric. {11/03/2018}									!


*** OPERATIONS ***

The flow of air through the model (via infiltration and ventilation) is modelled through a distinct nodal air flow 
network and so no air flow operations are included. {11/03/2018}

As of yet no casual gains (or profiles) have been added to the model. {11/03/2018}


*** CONTROL ***

Four provisional zone controls have been added although these are test placeholders rather than realistic schemes.
{11/03/2018}

The control schemes are as follows:

	1. One control for all times of all day types. Heating only with a setpoint of 15 degC. Ideal control.
	   {11/03/2018}

	2. One control for all day types. Heating only with a setpoint of 18 degC from 5.30am to 8am and a setpoint
	   of 15 degC at all other times. Ideal control. {11/03/2018}

	3. One control for all times of all day types. Heating only with a setpoint of 20 degC. Ideal control.
	   {11/03/2018}

	4. One control for all day types. Heating only with a setpoint of 20 degC from 5pm to 12 midnight and
	   a setpoint of 15 degC at all other times. Ideal control. {11/03/2018}


*** AIR FLOW NETWORK ***

A provisional air flow network has been modelled to capture the ventilation and infiltration of the flats. At the
present time, all thermal zones are associated with a fluid node and each are appropriately connected. The network
currently only deals with air movement through cracks/underpasses and through a mechanical vent in the bathroom.
{11/03/2018}

Details of the network are provided below:

	- Five boundary nodes. A wind induced node located at each of the four external windows and one (constant 
	  pressure node located 30m above the reference datum) representing the communal mechanical ventilation 
	  exhaust. {11/03/2018}
	- Seven internal unknown nodes, one for each of the thermal zones. {11/03/2018}
	- Five door underpasses (10mm x the door width). (Located at bottom of door.) {11/03/2018}
	- Five glazing/window cracks (2mm x perimeter of glazing). (Located at centre of the pane). {11/03/2018}
	- One constant flow mechanical ventilator located in the bathroom. {11/03/2018}

The naming of these components follows the following convention:

	- Boundary Nodes... Out-Efg_#. Where Efg and # correspond to associated zone and flat number as above.
	- Internal Nodes... efg_#. Where efg is lower case form of associated thermal zone designation.
	- Components....... EfgX_crk_#. Where Efg is zone designation; X represents surface type (W=window,
					    D=door,G=glazing)a; crk = crack* and # is flat number.
{11/03/2018}

* Currently cracks are the predominant component (alongside one extractor = EXT). These designations may be changed
  in the future. {11/03/2018}
