1. Introduction The aim of the paper is to investigate and optimize the Forrest Essentials factory’s workshop area in Uttarakhand in terms of fabric specifications and servicing. The space will be investigated based on heat loss and heat gains during an entire year for average and extreme temperatures. The results will be used to identify problems with fabric and servicing and suggest optimizations to reduce the annual energy demand.

1.1. Climate and Weather of the chose location The space is in Lodsi, Uttarakhand at 682m altitude (Figure 1). The site location falls under ‘Cwb’ region according to the Köppen-Gieger classification matrix (Kottek et al., 2006), depicting temperate climate with dry winters and warm summer.

In extreme summers the air temperature ranges from 12 °C to 44 °C. In extreme winters, the air temperature ranges from 1 °C to 33 °C. At its extremes, the location will receive 2350mm precipitation with its peak number of days in July (27 days) and August (26 days). Relative humidity (RH) greater than 90% has been recorded for all the months. The dominant wind direction is North-East (70% of hours) with highest ever recorded wind velocity of 12 meters per second in May (Figure 2).
