1. Q01

   To verify the savings from a Demand-Controlled Ventilation (DCV) retrofit in a tertiary building, IPMVP Option C with multiple regression including degree-days plus occupancy (measured through presence counters or badges) is typically the most appropriate approach.

   DCV savings depend on real occupancy patterns. The relevant model variables are degree-days (winter/summer weather), occupancy (badge entries, camera counting or smart-building data) and hours (weekdays, weekends, holidays). Multiple regression captures the correlations, allowing the savings to be evaluated by comparing the pre-DCV baseline to the post-DCV reporting period at equal conditions. Typical savings range from 15 % to 30 %.

2. Q02

   For a self-consumption photovoltaic (PV) installation, IPMVP proposes a modified approach: savings equal the PV energy consumed on site (self-consumption) plus the revenue from exported surplus, both quantified using two meters (PV production and grid import).

   Correct answer

   True

   Learning tip

   M&V on self-consumption PV requires explicitly metering PV production at the inverter and grid import at the point of supply. Total site consumption is derived as PV production plus grid import, self-consumption is PV production minus exported surplus, and monetary savings combine avoided purchase cost (self-consumption times retail tariff) with surplus times feed-in tariff. Routine adjustments still apply, mainly solar irradiation (solar degree-days) and occupancy, just as in a conventional Option B/C project. EVO publishes a dedicated renewable-energy addendum to IPMVP covering these PV-specific accounting rules.
