Environmentally Sustainable Design (ESD) Services

Carbon footprint reduction, passive systems, recycled energies, trigeneration

JHA is committed to Environmentally Sustainable Design (ESD) across the board on all of our projects.

We believe in the following key values:


Reducing things down the essentials as a foundation



Finding ways to do more with less


The creation of a whole that is greater than the sum of its parts

These are the fundamental principles behind our work in the built environment and what makes our Environmentally Sustainable Design (ESD) team get out of bed each day. We believe in striving for simplistic passive solar design as a foundation on all projects in preference to high tech bolt-on ‘ESD Initiatives’ wherever possible. The use of modern technology should be to complement excellent design, not to mask oversights of the architecture or services engineering.

Our team use a range of analytical techniques and dynamic simulation packages to provide rapid technical insight into the predicted operation of our projects. This allows informed changes to be made early in the design phase to optimise performance whilst the design is still fluid.

Our company personnel include Green Star, NABERS, ABSA, BREEAM, LEED, Estidama and GSAS accredited professionals, covering green building rating schemes across the globe and drawing upon the strengths of all of them in our daily work.

Simplicity is the ultimate sophistication
