§11-39-4 	General 	requirements. 	The 	provisions 	of
these 	rules 	apply when 	a 	comfort 	air 	conditioning
system or 	a 	ventilating 	system 	is 	to 	be 	installed 	in
buildings 	used 	or 	to 	be 	used 	as 	public 	buildings.
(1) 	New buildings. 	These 	rules 	apply 	to 	all 	new
buildings. 	New buildings 	mean 	buildings,
additions 	thereto 	and 	alterations 	thereof,
for 	which 	plans 	have 	not 	been 	approved 	by 	the
department 	previously 	or 	construction was 	not
in 	progress 	prior 	to 	the 	effective 	date 	of
these 	rules.
(2) 	Existing 	buildings. 	These 	rules 	apply 	to 	all
alterations 	or 	improvements 	to 	existing
buildings, 	including 	the 	replacement 	of 	any
major 	apparatus 	or 	device 	related 	to 	air
conditioning 	or 	ventilating 	systems. 	Existing
buildings mean 	buildings, 	additions 	thereto
and 	alterations 	thereof, 	structurally 	com-
pleted 	or 	for 	which 	plans 	have 	been 	approved
by 	the 	department 	and 	construction 	is 	in
progress 	prior 	to 	the 	effective 	date 	of 	these
rules.
(3) 	Change 	in 	use. 	These 	rules 	apply 	to 	every
building, 	or 	portion 	of 	a 	building, 	devoted
to 	new use 	for 	which 	the 	requirements 	under
these 	rules 	are 	more 	stringent 	than 	the
requirements 	covering 	the 	previous 	use.
(4) 	Design 	and 	preparation of 	plans. 	All 	plans
and 	data 	on 	air 	conditioning 	and 	ventilating
systems 	shall 	be 	prepared by 	or 	under 	the
direct 	supervision 	of 	a 	"designer." 	All 	air
conditioning 	insta1lations 	shall 	be 	designed
and 	installed 	to 	provide 	proper 	comfort 	as
defined 	in ASHRAE 	Standard 	55, 	unless 	con-
strained 	by 	laws 	of 	the 	United 	States 	of
America 	or 	the 	State 	of 	Hawaii 	for 	reasons 	of
conservation 	of 	energy.
(5) 	Refrigeration 	system. 	The 	entire 	installation
of 	refrigeration 	in 	connection with 	air
conditioning 	shall 	be 	in 	accordance 	with good
engineering 	practice 	and 	the 	provisions 	of
ANSI/ASHRAE 	15.

The 	department may 	on 	its 	own motion, 	or 	on 	the 	complaint
of 	any 	person, 	revoke, 	suspend, 	or 	deny 	a 	permit 	after
notifying 	the 	permittee 	or 	applicant 	and 	offering 	him

times 	when 	outdoor 	temperature 	is 	much 	lower 	than 	daily

be made 	in 	estimating 	the 	net 	instantaneous 	heat 	gains
in 	a 	building 	shall 	be 	in 	accordance 	with 	good
engineering 	practice.
(c) 	Infiltration. 	Infiltration 	air 	volume 	rate
and 	the 	sensible 	and 	latent 	heat 	gains 	therefrom 	shall
be 	determined 	for 	air 	conditioning 	systems; 	and where
calculated 	infiltration 	rate 	differs 	from 	required
outdoor 	air 	rate, 	the 	larger 	quantity 	shall 	be 	used 	for
calculating 	the 	cooling 	load.
(d) 	Control. 	Provision 	for 	reasonable 	control 	of
temperature 	shall 	be made 	for 	all 	air 	conditioning
systems. 	[Eff. 	JAN 3 1 1983 	] 	(Auth: 	HRS 	§§321-9,

§11-39-8 	Outdoor 	air 	supply. 	(a) 	The 	outdoor
air 	shall 	be 	taken 	from 	a 	clean, 	uncontaminated 	source.
(b) 	Outdoor 	air 	shall 	be 	ducted 	to 	the 	air 	condi-
tioning 	or 	ventilating 	apparatus, 	or mixed with
recirculating 	air 	in 	a 	plenum. 	Wherever 	the 	outdoor
air 	duct 	is 	not 	connected 	to 	the 	apparatus, 	the mixing
plenum 	shall 	be 	properly 	engineered 	and 	free 	from 	air
contamination 	sources.
(c) 	All 	outdoor 	air 	intakes 	shall 	be 	screened 	and
shall 	be 	located 	as .far 	as 	possible 	from 	stacks 	and
vent 	outlets, 	but 	this 	distance 	shall 	in 	no 	case 	be
less 	than 	twelve 	feet 	(three 	and 	five-tenths 	metres).
Domestic 	clothes 	dryer 	vents 	shall 	not 	be 	considered as
outlets 	for 	this 	purpose. 	The 	distance 	in 	each 	case
shall 	be 	sufficient 	to 	prevent 	the 	discharged 	air 	from
entering 	the 	outdoor 	air 	intake.

(4) 	If 	agreed 	between 	the 	designer 	and 	the
director, 	a 	particular occupancy 	in which
tobacco 	smoking 	is 	illegal 	and 	does 	not
occur, 	may 	have 	reduced 	outdoor 	air 	require-
ments, 	where 	based 	on 	a 	specified 	amount 	per

exhaust 	air.
(b) 	Requirements 	of 	air 	purity with 	regard 	to
dust 	contained 	therein 	shall 	be 	assumed 	to 	be 	met 	if

(a) 	Ventilating 	systems 	within 	the 	scope 	of 	these
rules 	shall 	provide 	the 	required 	ventilation 	service
for 	all 	occupied 	areas 	for 	which 	such 	form of 	ventila-
tion 	is 	to 	be 	used. 	Systems 	shall 	comply with 	all

air 	quantities 	shall 	be 	guided 	by ASHRAE 	Standard 	62.
Filtration 	shall 	be 	applied 	to mechanical 	ventilation
supply or make-up 	air.
(b) 	Ventilation 	for 	restaurant 	cooking 	equipment.

shall 	be 	guided by NFPA Standard 	96.

above 	the 	highest 	roof, 	and 	higher 	than 	any
adjacent 	roof 	at 	the 	property 	line, 	a 	grease

the 	designer 	furnishes 	details 	in 	his 	permit
application, 	the 	installation 	is 	in 	accordance
with 	the 	agency's 	approval.
(3) 	Hood 	and 	duct 	design 	shall 	be 	indicated 	on
plans, 	to 	scale, 	with 	exhaust 	air 	and 	filtered
make-up 	air 	quantities 	indicated.

tions 	or 	test 	results 	satisfactory 	to 	the
director 	shall 	be 	provided.
(c) 	Toilet 	exhaust 	shall 	be 	four 	cfm per 	square
foot 	of 	toilet 	room 	floor 	area. 	If 	the make-up 	air 	is
air 	conditioned, 	the 	exhaust 	rate may 	be 	reduced 	to 	two

§11-39-13 	Garage 	ventilation. 	Ventilation 	for
enclosed 	automobile 	parking 	garages 	shall 	be 	guided 	by
the 	following:
(1) 	Each 	story 	or 	level 	of 	a 	parking 	garage 	shall
be mechanically 	ventilated 	unless 	all 	of 	the
following 	requirements 	are 	met:
(A) 	More 	than 	half 	the 	wall 	area 	is 	open, 	in
a 	wall 	length 	of 	at 	least 	(forty 	per
cent) 	the 	perimeter;
(B) 	There 	is 	no 	parking 	attendant 	or 	other
employee 	normally working 	in 	the 	space;
and
(C) 	There 	is 	no 	such unusual 	or 	irregular
shape 	of 	the 	story 	or 	level 	that 	the
majority 	of 	the 	area would 	usually 	not
receive 	natural 	air 	motion.
(2) 	Mechanical 	ventilation 	for 	parking 	garages
shall 	require 	a 	minimum of 	one 	and 	five
tenths 	cfm per 	square 	foot 	(seven 	and 	five
tenths 	liters 	per 	second'per 	square metre)
over 	the 	entire 	floor 	area 	requiring 	ventila-
tion. 	At 	locations 	where 	traffic 	is 	such
that 	congestion 	can 	occur, 	for 	example 	at 	an
exit, 	the 	air 	distribution 	shall 	be 	adjusted
to 	provide more 	air.
(3) 	Ventilation may 	be 	by 	supply 	or 	exhaust, 	but
shall 	be 	arranged 	for 	reasonably 	even 	air
distribution.
(4) 	An 	engineered 	system may 	be 	employed, 	using
the 	equation: 	Q = Kn/C, 	where 	Q = exhaust
ventilation 	rate, 	cfm; 	K = 1,380,000 	(a

hardships 	in 	complying with 	these 	rules, 	the 	director
may make 	a 	variation 	or 	temporarily 	set 	aside 	such
