PV+CHP hybrid system can enable the share of solar PV to be expanded by
about a factor of five (Nosrat and Pearce, 2011; Pearce, 2009).
Notes
1.
Passive solar building:
a building that uses solar gains to reduce heating
and possibly cooling energy consumption based on natural energy flows
- radiation, conduction, and natural convection. The term “passive
building” is often used instead of passive solar, particularly for
cooling-dominated climates where natural ventilation is essential.
2.
Alinear lumped parameter system can berepresented byasetofordinary
differential equations and thermal networks. A number of formulation
important subset of linear systems are those with time-varying
coefficients - also common in building energy analysis, where we can
often represent some thermal conductances, such as a known but
variable level of natural ventilation (or time-varying infiltration).

4.
The TFM terminology used by ASHRAE and others refers usually to time
domain coefficients and weighting factors based on
z
-transforms and not
Laplace or frequency domain transfer functions.
5.
The number of poles is related to the number of wall layers (thermal
capacitances) in a multilayered wall model. With no discretization, we
have essentially infinite layers, infinite number of capacitances, and an
infinite number of poles.
6.
Building-added photovoltaics (BAPV) are also often referred to by many
authors as BIPV - such as roof-mounted (ballasted) PV systems on
racking structures. In this article, BIPV refers to PV modules integrated
into the building envelope (roofs, walls) as an exterior layer.

irradiance of 1000 Wm
