VIP+ logo

Whole-building energy analysis program calculating hourly energy performance for a full year. VIP+ can also be used for economical and environmental calculations. Screen Shots

Keywords

energy performance, code compliance, design, research, residential and commercial buildings, costs, environmental sustainable

Validation/Testing

IEA-Bestest and 20 years of empirical testing. Bestest result is published on website.

Expertise Required

Understanding of basic energy flows and building construction.

Users

About 150 user organizations both academic and business, mostly in Sweden. Each organization comprising 1 to 20 licenses.

Audience

energy advisers, architects, building owners and managers, schools, product manufacturers

Input

In windows dialog boxes you enter geographic location and building orientation, micro climate adjustment, building materials and building parts (walls, windows, shading surfaces, openings etc.), operating schedules, HVAC equipment (ventilation, heat pumps, solar panels etc.) and controls, utility rate schedule, energy costs etc. Multiple zones can be calculated. Climate files can be imported from Meteonorm and other sources.

Output

Three calculations are performed, the first two to test code compliance the third for comparison against real consumptions. Detailed output selectable from monthly to hourly over a year. Output can also be exported to txt file.

Computer Platform

PC, Windows

Programming Language

C++, Fortran

Strengths

A fast and very accurate way to see how much energy a building should consume. Very strong models for heat accumulation, infiltration, solar radiation and ground coupling. Calculation time is under 1s. Together with Meteonorm energy can be calculated on any given point on the earth surface.

Weaknesses

Can't simulate dysfunctional HVAC equipment. We don't recommend using it for dimensioning HVAC equipment.
