The plumber or tinsmith is no more

of a health, wellness and

comfort contractor than a framer is a

cabinet maker.

There is a difference!


Failure to Communicate!The construction industry thinks a health, wellness and comfort is a

tinsmith or plumber…

Consumers equates plumber to someone who unplugs toilets and

fixes leaks. Does Tin Bashing sound soothing?


HVAC Systems can be threatening or

therapeutic towards the aging process…

hvac M UST be repositioned in the minds of consumers a s a health,

wellness and comfort issue.

The energy index climbed 7.3% between February 2004 and

Informal care creates a domino affect on

informal care givers and the building

environment.

Canada


One-half of the family and friends who provided personal care to seniors had to change their social activities (52%) because of their care giving

duties.

Canada


More than one-third had to alter their holiday plans (39%).

Roughly one-third also suffered disturbances to their sleep (31%) and

health (29%).

One out of every two caregivers had to

incur extra expenses (55%) related to care giving.

Alzheimer's Facilities


Adapted from seniorresource.comCopyright© Robert Bean, 2004

Continuing Care Retirement Communities (CCRCs)

•Active seniors - independent lifestyle

•Private home - regardle ss of future medical needs.

•May require buy-in, o r an up-front annuity purchase followed by monthly payments covering se rvices, amenities and needed medica l.

•Availabil ity of multiple levels of care, without the uncertainty of wondering where you will live.


Adapted from seniorresource.com


Congregate Housing

•Independent l iving - priva te separate apartments

•Opportunity to share activities of daily living with other residents as one chooses.

•They may offer rental or ownership units.



Assisted Living

•Offers help with non-medical aspects of daily activitie s in an atmosphere of separa te, private l iving units.

•It can be likened to Congregate living for re sidents less able to function independently in all aspects of their daily lives.



Board and Care

•Board and Care is usually offered in what may appear as a converted home.

•It provides a homelike setting with supervision and ca re for 4-10 residents


Adapted from seniorresource.com



•Skilled Nursing Facilities may be freestanding, or pa rt of a seniors community offering any or al l of the following:

•Congregate, Assisted Living, Continuum of Care

•It may special ize in Short Term or acute nursing ca re, intermedia te or long te rm skil led nursing ca re.




• Early stage patients - accommodated in a Congregate o r Independent wing of a multi-level campus.

• Many Assisted Liv ing Communit ies will accept and successfully house ea rly stage residents.

• As the disease progresses pa tients may develop argumentative behavior, "sundowning" and wandering habits.

• Generally the communit ies best equipped to deal effectively with this middle stage patient are Alzhe imer' Communities.

How Do We Define It?



What environmental

condition influences

our aging process

more than any other

aspect of our lives?

Aging & The Environment…


“...the careful

regulation of body

temperature is

critical to comfort

and health.”ASHR AE Fundamentals 2001

Comfort & Health…


“...the judgment of comfort

is a cognitive process

involving many inputs

influenced by physical,

physiological,

psychological, and other

processes.”

The Mind & Body Interface…


thermal perception

factorsdemographics

(gender, age, economic status)

context (building design, building func tion,

season, clima te, se mantics , so cial

conditioning)

cognition

(attitude, preference, and expec tations)(McIntyre 1982, Baker 1993, Baker and Standeven 1994, Oseland 1994a,b,

Griffiths et al 1988).

Factors…


Every thing you

need to know about

your health and

wellness in your

home environment

you experienced

before grade

school...

The Good News…


“…characteristically,

people seek to be

comfortable, and

take actions to

secure thermal

comfort; the

motivation to do so

is powerful”

The Motivation…


“We do not seem to

recognize that our

real customer is the

occupant, not the

building.”

H.F. Levy, P.E.

Professional Engineer & (Life Member ASHRAE)

The Challenge…

10


...the sad truth

according to

Decisions Analysts

Home Comfort

Survey™ is only 50%

of occupants are

actually satisfied...

The Benchmark…


“…the percentage of

physical measurements of

indoor climates actually

meeting the

recommendations of

ASHRAE Standard 55 was

remarkably low … ranging

from an average of 6% in

summer to 21% in

winter.”

The Opportunity…


“The purpose of this standard is

to specify the combinations of

indoor the rmal environmental

factors and pe rsonal factors

that will produce the rmal

environmental condit ions

acceptable to a majority of the

occupants within the space.”

The Standard…


Understanding

human

physiology is

the first step

in gaining

control.

First seek to understand…


Our thalamus is

responsible for letting

our brain know what's

happening outside our

body.
