The healthcare

sector is changing

The healthcare sectr is facig a big

dilemma. O e had, the medical

fferig ad patiet care ptis are

cstatly beig imprved ad ew

health isurace premiums. The

situati is amplified by the icreasig

tha it was 50 years ag.

I additi t this, cscietius use

a ecmic issue i hspitals. The true

task csists f cmbiig eergy effi-

The icreasig privatizati f fiacig

hspitals ad cliics als serves t i-

crease cmpetiti. The fight fr slvet

private patiets has already started. May

facilities have t be revated t gai

leverage i this cmpetitive evirmet

i rder t ffer the required cmfrt ad

keep csts uder ctrl.

Thse respsible fr buildig techl-

prve themselves i this evirmet f

icreasig cmpetiti. Their bjective is

t esure the best pssible patiet care

(patiet satisfacti) withi a high-per-

frmace mtivated rgaizati (staff

ability) ad a high stadard f reliability

(quality).

The swe: itegted buildigslutis

Buildig techlgy is a key t success. It

secures cmfrt, hygiee ad the safety

f patiets ad staff while allwig fr

streamlied perati ad a high level

f eergy efficiecy. Therefre, mder

buildig ad security techlgy is a

imprtat cg i hspital ad ut-patiet

I rder t ctiue meetig icreas-

ig requiremets with regards t eergy

supply, cmfrt, security ad prfitabil-

ity, the systems icreasigly have t be

itegrated i a buildig. Netwrkig all

Climate chage ecessitates ew slu-

tis fr eergy ptimizati. Amg

ther thigs, these slutis are required

t reduce greehuse emissis. The

Eurpea Ui (EU) has set as its bjec-

tive t reduce the eergy csumpti f

buildigs by 27 percet by the year 2020.

I rder t achieve this, mderizati

has t be accelerated ad effective meas-

ures fr icreasig eergy efficiecy have

t be implemeted.

Energy-intensive

processes in hospitals

Electrical supply, media supply ad air

cditiig techlgy are all part f

what makes a successful hspital. I addi-

ti t this, wrk that prtects resurces

ad cst savigs ctribute csiderably

t achievig busiess bjectives.

The fllwig figures clearly shw the

relevace.

Fuels are used primarily fr heatig

ad fr prducig warm water. Electrical

eergy is primarily used fr lightig advetilati. Tgether they are resp-

sible fr apprximately 75 percet f a

hspitals ttal eergy csts. O average,

Germa hspitals csume apprximate-

ly 300 kWh thermal eergy ad ver 100

kWh electrical eergy per square meter.

Mst hspitals share specific features that

sigificatly impact eergy csumpti.

Amg ther thigs, these iclude:

Heat requiremets fr prducig

warm water thrughut the year with

a temperature level that smetimes

exceeds 60C.

Ofte simultaeus requiremets fr

Cstat pwer requiremet distribut-

ed ver the curse f a day ad thrugh-

ut the year.

Ctiual requiremet fr air cdi-

tiig.

Hwever, may hspitals have ld

systems i eed f revati. Thus,

csiderable savigs ptetials are left

utapped. Practical examples shw that

savigs f 25 t 40 percet are realistic

after implemetig the apprpriate

revati measures.

Due t the fact that fssil fuels will ly

be able t be used t a limited extet

i the future, hspitals are als faced

with the issue f future eergy availabil-

ity. Ruig hspitals ad ut-patiet

departmets require a uiterrupted

supply f eergy every day. This is eve

ecessary t prevet life-threateig situ-

atis, as ca be the case durig surgery.

We supprt hspital peratrs whe it

cmes t the eergy issue: by prvidig

secure eergy supply ad distributi,

via eergy-savig ctractig, via precise

kwledge f csumpti ad ptimiza-

ti ptis with buildig maagemet

systems as well as via ew, eergy-pti-

mized systems.

Lwered csumpti f resurces,

lger system perati as well as bet-

ter maiteace ad repair f a device

usually result i lwer peratig csts. If

all these factrs are take it csidera-

We supprt the GreeBuildig prgram:

This is a vlutary prgram iitiated by

the Eurpea Cmmissi t imprve

Accrdig t the gree bk f eergy

I rder t be able t reduce eergy

ti first has t be measured. The

measured data is subsequetly csli-

prvides the fudati eeded fr

Eegy lysis

Progressive technologies for energy

savings have to be developed on an

ongoing basis. We have the knowledge

and the experience required to analyze

a hospitals energy results in a meaning-

ful manner comparing values to gener-

ate benchmarks, which can be used asthe foundation for optimization.

Eegy ptimizti

Eergy ptimizati is custmized t

meet the requiremets f each hspital.

It is based the results f the eergy

measuremets ad subsequet aaly-

sis. This icludes the ptimizati f

hspital perati busiess prcesses.

Existig buildigs

I a existig buildig, eergy cst

In cases of room modifications, the

building technology is adjusted to suit its

Hygiene

I a hspital, hygiee is a daily challege:

New patiets, visitrs ad persel e-

ter the hspital every day. They all brig

ivisible viruses it the hspital. Fd

ad ther gds are als delivered a

daily basis. It is impssible t keep a place

with s much ctact ad mti free f

germs! Accrdig t a specialist medical

study eight t twelve percet f hspital

treatmet prcedures are hidered by

scmial effects r, i ther wrds,

ifectis acquired i the hspital.

Rm vetilati systems i the hspital

serve t maitai the required thermal

rm climate, extesive filterig f mi-

crrgaisms ad dust, aesthetic gases

ad drs i the air as well as the dissipa-

ti f heat lads. Here it is f utmst

imprtace that the thermal effects adpressure effects remai uder ctrl at

all times especially i surgery rms.

Air currets travelig frm e area t

ather ca be especially dagerus fr

hygiee. Fr example, cstructi dust

has a high percetage f fugus spres.

Therefre, cstructi measures i

hspitals have t be especially carefully

plaed. It pays t sped a bit mre

cstructi separati measures.

Dge psed by legiell

Legiella are bacteria primarily fud i

water ad damp evirmets, ad thus

they are fud i buildig techlgy

systems. They are a atural cmpet

f the micrflra f water. Drikig water

frm the lcal water supply lies always

ctais a limited umber f differet

bacteria. This culd als iclude legiel-la i exceptial cases.

The multiplicati f these represets

a hygiee risk ad this ca be caused

iside buildigs if water stagates ad is

warmed. Warm water systems are thus t

be istalled ad perated s as t make

legiella multiplicati impssible.

Lw tubulece displcemetcuets

Lw turbulece displacemet currets

are supplied t the peratig rm via

a ceilig vet. It is especially imprtat

here that the rm temperature is higher

tha the temperature f the supplied air.

This causes the supplied air t be mved

dw by the thermal effect ad esures a

high level f hygieic safety. The perat-

ig ad istrumet tables are shielded

frm micrrgaisms i the air by the lw

turbulece displacemet curret. With

this type f vetilati, the risk is lw

that germs frm the utside will eter.

The highest level f hygiee regulatis

The ight tempetue tll times

The temperature f the supplied air is

imprtat fr the cmfrt f the team

f surges. I peratis requirig great

physical effrt such as isertig a hip

prsthesis, the team f physicias fte

requires a cler temperature tha i

relatively fier peratis. I the past,

the temperature i the peratig rm

was regulated directly frm the rm

ad the guidelie was 21C +/- 3C.

Tday, the temperatures are set frm the

ctrl ceter. Key figures are idividu-

ally allcated t each surge, s that

each pers ca wrk i a evirmet

matchig their prefereces.

Humidity d dust

Relative humidity als plays a imprtat

rle i the air quality. Mst peple per-

ceive relatively dry air t be ucmfrt-

able: Studies have revealed that air with a

higher level f humidity tha the refer-

ece value f 30 percet ca be experi-

eced as t dry by tested perss.

Hwever, a icrease i humidity ca

als prve t be prblematic. If there is

t much humidity, mildew develps at

places where water stads ad especially

i shwers ad baths. Fugus spres

are t dagerus fr peple with itact

fte d t have sufficiet defeses.

Therefre, gd air exchage with clea

filtered air is mre imprtat tha humid-

ity fr health. Tw utside air systems

Fr example, i Switzerlad it is c-

taied i article 19 f the medical prd-

uct rdiace frm the year 2001: The

The EU directive serves as a legal frame-
