Aero Manufacturing Unit Location: Rohtak, Haryana

Type: Industrial Area : 1400 m² Client:- AERO Fasterners Scope:- Integrated Building Design, Building Services Engineering and Construction Management The building was approached to provide a comfortable and healthy environment with a use of passive strategies. The spaces were designed to provide 100% daylight spaces.

Thermal & airflow modelling

The recessed windows are optimized to cut the direct solar radiation. The shading mesh further cuts the sun angle. The ventilation shaft increases the ACH and allows the cross ventilation. The skylight and windows are designed to provide daylight throughout the building.

The envelope is designed which reduced the heat gain and even reduced the operational cost of the air conditioning in the office spaces.

The canopy is designed to provide a comfortable outdoor space and integration of solar panel to produce the energy.

Radiant ceiling design was found to perform better than VRF system due to division of load into sensible and latent being served by separate units. Due to lesser latent loads Radiant system works better from January to May & October to December. During monsoon months the load on the chiller for DOAS increases due to very high latent load.

Comfort hours from both the systems were compared for representative zones were analyzed with IMAC Band. Comfort map for 2nd Floor open office for both cases is shown below. On an average for the entire building comfortable hours are 93.1% in Radiant but here the humid hours have also reduced as compared to VRF case. In VRF there are 92.2% Hours comfortable.
