Operating energy use may be increased by maintaining the negative pressure requirements for interior designated smoking rooms. Designated smoking rooms in commercial properties can also add upfront costs associated with construction and design, added ventilation loads, and air sealing and deck-to-deck partitions. On the other hand, increased air sealing can decrease energy costs and increase rents, as noted earlier.
The mechanical engineer ensures that the HVAC design meets the exhaust and pressure levels of the LEED requirements. Also ensure that all units will receive adequate fresh air. A certain amount of air
There are fewer codes and associated costs for collecting and reusing stormwater for irrigation than for interior water reuse. Captured stormwater can often be reused for irrigation without much treatment.
Installing a green roof is one successful way to control and treat stormwater. Different types of green roofs provide varying levels of stormwater management, amenity, benefits and maintenance requirements. While green roofs can be expensive, they can often reduce the costs of traditional stormwater systems for a net savings.
Bioinfiltration strategies on streets and parking lots, such as vegetated filter strips and grass swales, are alternatives to typical curb and gutter design that allow for infiltration of stormwater, as opposed to conveying the runoff to storm drains.
