Arrow animations in 3D visualize ventilation air flows, window energy balance, and wind driven flows. There are special reports for LEED submittal forms included. The diagram plots deliver vector graphics which allows detailed result analysis in custom reports. Results can be exported to Microsoft Word or Excel. A single zone IDA ICE model with ...
It requires metering for indoor, outdoor, and wastewater uses, as well as maximum flow rates for water-based heating, ventilation, and air conditioning systems. The chapter also includes requirements for water treatment systems, rainwater harvesting, greywater systems, and reclaimed water systems.
DOAS air handling unit with heat recovery wheel and passive dehumidification. A dedicated outdoor air system (DOAS) is a type of heating, ventilation and air-conditioning system that consists of two parallel systems: a dedicated system for delivering outdoor air ventilation that handles both the latent and sensible loads of conditioning the ventilation air, and a parallel system to handle the ...
LEED has evolved since 1998 to more accurately represent and incorporate emerging green building technologies. LEED has developed building programs specific to new construction (NC), core and shell (CS), commercial interiors (CI), existing buildings (EB), neighborhood development (ND), homes (LEED for Homes), retail, schools, and healthcare.
A03 Ventilation Design topic, the WELL assured building to have existing or new mechanical ventilation systems following ASHRAE 62.1-2 or EN standard 16798-1 or AS 1668.2 or CIBSE Guide A: Environmental Design. Naturally ventilation can also be used without mechanical ventilation system if the design follows Natural Ventilation Procedure in ...
The LEED Green Building Rating System (LEED) is a program that provides third-party verification of green buildings. The LEED program rates commercial buildings, homes, neighborhoods, retail, healthcare, schools, including every phase of the respective building lifecycle, including design, construction, operations, and maintenance.
The toughest requirements apply to large commercial buildings. Starting in November, new permit applications for high-rise residential building must submit documentation to achieve LEED certification, and that requirement ratchets up to LEED Silver in 2009 and LEED Gold in 2012.
In the case of an ideal lossless fan system (i.e. =) the SFP is exactly equal to the fan pressure rise (i.e. total pressure loss in the ventilation system). In reality the fan system efficiency is often in the range 0 to 60% (i.e. η t o t < 0.6 {\displaystyle \eta _{tot}<0.6} ); it is lowest for small fans or inefficient operating points (e.g ...
