Part One: The how and why of Passivhaus
|
The Passivhaus energy standard, the Passivhaus concept, common misconceptions, retrofitting and the EnerPHit energy standard |
|
|
Economic culture, energy costs and supplies, factors affecting property prices, factors affecting Passivhaus costs, methods of determining cost-effectiveness |
|
|
Certification of buildings, building components, designers and contractors; the process and information required for building certification |
|
|
Challenges of meeting the Passivhaus standard UK building culture, education and employment in construction, professional expertise, risk-aversity, the planning system, vernacular styles, the team approach, the disadvantages of a Passivhaus, Passivhaus and other low-energy standards |
|
|
Natural materials, zero carbon and resilience Natural and low-embodied-energy building materials, zero carbon and the Code for Sustainable Homes (CSH), on-site low- or zero-carbon energy, post-peak energy, energy returned on energy invested (EROEI) |
|
|
Setting up a Passivhaus project Choosing a plot, planning considerations, retrofit considerations, phased retrofitting and extensions, selecting an architect and builder, the role of the client |
