Health and Well Being

Many factors influence whether a building has a positive or negative impact on its occupants.

The use of wood as a structural or finish material has made a unique contribution, with a focus on indoor air quality, acoustics, physical health, and a natural, positive human response to wood that has always been intuitive, but is increasingly being proven by research and experience.

“ It's about designing places where people want to be”

 

Wood promotes Health and Well Being because

Wood products are beautiful, natural, durable and sustainable – and the only major building material that grows naturally. The use of wood products can also improve indoor air quality by moderating humidity because Wood is a natural humidity regulator: its moisture content always matches the ambient air, providing natural humidity stabilization and regulation, which is an important factor.

Humidity Control The use of wood products can also improve indoor air quality by moderating humidity. Acting like a sponge, the wood absorbs or releases moisture in order to maintain equilibrium with the adjacent air. This has the effect of raising humidity when the air is dry, and lowering it when the air is moist – the humidity equivalent of the thermal flywheel effect. 

 

Wood and Interior Air Quality Dust and Particulates

Solid wood products, particularly flooring, are often specified in environments where the occupants are known to have allergies to dust or other particulates.  Wood itself is considered to be hypo-allergenic; its smooth surfaces are easy to clean and prevent the buildup of particles that are common in soft finishes like carpet.

Solid wood products are often specified in environments where the occupants are known to have allergies to dust or other particulates. 

A recent study by the University of British Columbia and FPInnovations established a link between wood and wellness. The joint research project found that the visual presence of wood in a room lowers sympathetic nervous system (SNS) activation in occupants. The SNS is responsible for physiological stress responses in humans. In the developed world where people spend much of their time inside buildings, the design of the indoor environment is of critical importance to human health.  The results found that “Stress, as measured by sympathetic nervous system (SNS) activation, was lower in the wood room in all periods of the study.”

Health and well-being embraces both physical health, and the psychological aspects of human performance. Over time, physical issues have been dealt with incrementally through legislation that has banned the use of toxic or otherwise dangerous substances in buildings. In addition, new standards have been introduced to ensure adequate ventilation, reduce condensation and inhibit the growth of mold and mildew.

Designers are also interested in potential psychological and related physiological benefits of environmental design factors. For example, intuition tells us that a connection to nature improves our sense of well-being when indoors. This can be achieved through access to daylight or views, or by providing a visual or tactile connection with natural materials such as wood and stone. For many years, research has shown the human health benefits of forests. The benefits of time spent in forests include reduced stress, lower blood pressure, and improved mood. Medical research shows exposure to forests can boost our immune system and may even correlate to lower cancer rates.

The benefits of forests are strongly recognized in some cultures. In Japan, the term “forest bathing” refers to time spent in the forest atmosphere and is encouraged by public policy. 

Surrey Memorial Hospital, Surrey, B.C. Architects: CEI Architecture and Parkin Architects report that People that spend a lot of time in a state of SNS activation can demonstrate evidence of physiological and psychological impact. The use of visual wood surface can reduce SNS activation and promote health in building occupants.

The Critical Care Tower (CCT) at Surrey Memorial Hospital provides strong evidence that Canada’s healthcare sector now recognizes the important role that can be played by wood in the creation of healing environments. “Sustainable design goes hand-inhand with healthcare design,” says Bill Locking, senior partner with CEI Architecture and partner in charge on the project. In January 2015, Surrey Memorial Hospital achieved LEED Gold certification. Architect Bing Thom said he chose wood for key structural components in the retail and commercial development at Central City, Surrey, B.C. “to provide a warm and tactile contrast to the smooth, synthetic environment of the modern high-tech work space.” The growing knowledge of the health benefits of building with visual wood surfaces is being incorporated into healthcare environmental to support patient recovery, school environments to support student learning, and offices to support employee health.
