closet and also for appropriate entrance mats. These should be included in the design.
- The remaining strategies in this category have to do with the design of the
lighting and HVAC systems. Providing for better occupant control of these systems allows
for a more user-friendly and healthier environment. A follow up survey is recommended
to ensure the occupants are comfortable with the end results. Incorporating sufficient
lighting and thermal controls into the design now is much more cost efficient than
trying to add them later. We recommend including these strategies into the design now
where possible.
- Strategies for day lighting and views to the exterior have been mentioned above
and should definitely be included. The existing portions of the building may benefit
from larger window areas or the installation of inexpensive tube skylights, while the
new addition should include this in the design. It will be more difficult to provide 90%
of the existing spaces with direct views to the exterior, but should be studied further for
possibilities.
