The Passivhaus standard is much more than an energy performance standard, it is also a quality assurance standard that closes the gap between theoretical performance and reality. The Passivhaus Planning Package (PHPP) software is a rigorous design tool for analysing Passivhaus buildings, making the designer subject to an inbuilt quality assurance that can meet the actual performance targets of the proposed design and specification.
If a client of Paul McAlister Architects desires a Passivhaus building there is a distinct advantage in employing a certified Passivhaus designer who has already demonstrated the knowledge and the skills required. The practice is also a member of the Passivhaus Buildings Trust, a new organisation established by the AECB, committed to assisting with the delivery of buildings that perform as intended.
