dbHMS used IESVE for Engineers to carry out detailed daylighting studies and energy modelling to make Nutech one of India’s most sustainable factories
IESVE for Engineers was used to carry out detailed daylighting studies and energy modelling to help make the proposed new Nutech Packaging Factory one of India’s most sustainable factories. The analysis, carried out by dbHMS, informed many key decisions during the design process which were instrumental to the sustainability of the building. The factory is set to achieve Gold Certification under LEED India.
dbHMS are the specialist sustainability, daylighting and energy modelling consultants for the project. They are also LEED assessors. The consultant’s role was to model the various proposed design options to ensure the optimum, low energy construction solution and building form were selected to enable the building to achieve its energy targets. To model the factory dbHMS relied on IESVE for Engineers.
The consultants modelled the fabric thermal performance for the proposed new factory using IESVE software including ModelIT, the single central 3D data model at the heart of the system which provides geometry and data shared by all tools and ApacheSim, dynamic thermal simulation software. The aim of the modelling was to establish which form of construction of the factory envelope was most effective in limiting the heat gains in the ground floor factory and the first floor offices. The offices are occupied from 9am to 6pm, while the factory operates around the clock.
Having modelled all the proposed construction options in Vista for each construction element (wall, roof and glass), dbHMS was able to provide an accurate comparison of the effectiveness of each material in helping limit heat gains inside the offices and factory. The final, most effective construction solution was based on using autoclaved aircrete block walls, high performance single glazed windows and 150mm reinforced concrete slab roof with 50mm insulation.
In addition, modelling showed that a glazed area of 40% was the most effective daylight option, when combined with skylights over the workshops, to achieve the required lux levels in the office and factory spaces.
“IESVE for Engineers has ensured that the Nutech Packaging Factory in Greater Noida is one of the most sustainable factories in India.”
