This Case Study outlines developing a DTS Solution and a Performance Solution for the energy efficiency of the facade of a hotel. It is based on the DTS Provisions in Section J, Part J1 Building fabric in NCC Volume One, as well as the Verification Method, JV3 Verification using a reference building.

This Case Study aims to demonstrate the practical application of J1 and JV3 for a hotel with substantial glazing. The design scenarios considered include:

wall-only R-Value
percentage glazing allowance
fixed glazing Total System U-Value
fixed glazing Total System SHGC
fixed glazing area
horizontal shading.
This Case Study reflects requirements in NCC 2019 Volume One.
