This route requires an approved competent person using certified software, to model a reference building that meets all the prescriptive (deemed-to-satisfy) requirements. These results are then compared to an energy modelled Rational Design of the actual building, whose performance should exceed that of the reference building.
WHY CHOOSE DEBCAL TO PERFORM A RATIONAL DESIGN?
Rational Design Pro's
CREATIVE & DESIGN FREEDOM
We achieve compliance while :
Maintaining architect's creative and design freedom
Maintaining the integrity of design
Eliminating the restrictions of the Prescriptive Route
REAL ENERGY SAVINGS
We find energy efficiency solutions unique to that design
We introduce substantial energy saving measures
We go beyond the minimum requirements as prescribed
We ensure real energy efficiency.
REAL COST SAVINGS
We find significant construction cost savings
We recommend simple, easy to implement solutions
We produce buildings that are cheaper to operate, reducing monthly electricity bills, and saving clients money over its lifespan.
(please see projects page for more on savings)
Rational Design Con's
VERY FEW...
Slightly higher cost up front
Slightly longer turnaround time
(Approx. 5-8 working days, depending on size of project)
To the client's benefit, the initial cost of a Rational Design is always offset firstly by construction cost savings and then, by reduced operating costs over the lifetime of the building.
This makes it a very cost effective and economical choice that developers are willing to pay, and a preferred route to compliance.

Proven Track Record:
Zimbali Development
A R27mil project realised construction savings of 6.31% (R1 741,962.00)
House Kirk
Glazing installation costs reduced by R94 388.42 and more.
House LEK
Compliance achieved while maintaining original design.
Weigh up the cost of Rational Designs with their proven benefits, and you will find that it makes monetary sense to choose this route to compliance. It is our preferred route in terms of cost effectiveness, for both the construction period and for the lifespan of the building.
In spite of the complexity of energy modelling, the solutions are often simple, economical and easy to implement.
