A data-driven multivariate estimation of building heat demand: The case of the Canton of Vaud

2025

Abstract

According to the Horizon 2030 roadmap of the Canton of Vaud's Real Estate Strategy, increasing the energy efficiency of existing buildings is essential to achieve a zero-carbon balance by 2040, with an intermediate target of reducing CO2 emissions by 50-60% by 2030. In this context, precisely assessing and monitoring heat demand and greenhouse gas emissions is crucial. This paper presents an integrated methodology that leverages multiple publicly available datasets to reconstruct buildings' geometric and structural characteristics in the Canton of Vaud. The extracted features are then used to estimate building heat demand based on the SIA 380/1 (2009) standard. Results demonstrate that detailed reconstruction of building characteristics enables accurate heat demand estimations, with relative errors under 20% for buildings with standard geometries.

Greenhouse gas emissions

Greenhouse gas emissions (abbreviated as GHG emissions) from human activities strengthen the greenhouse effect, contributing to climate change. Carbon dioxide (), from burning fossil fuels such as coal, oil, and natural gas, is one of the most important factors in causing climate change. The largest emitters are China followed by the US, although the United States has higher emissions per capita. The main producers fueling the emissions globally are large oil and gas companies.

Renewable heat

Renewable heat is an application of renewable energy referring to the generation of heat from renewable sources; for example, feeding radiators with water warmed by focused solar radiation rather than by a fossil fuel boiler. Renewable heat technologies include renewable biofuels, solar heating, geothermal heating, heat pumps and heat exchangers. Insulation is almost always an important factor in how renewable heating is implemented. Many colder countries consume more energy for heating than for supplying electricity.

Heat pump

A heat pump is a device that uses work to transfer heat from a cool space to a warm space by transferring thermal energy using a refrigeration cycle, cooling the cool space and warming the warm space. In cold weather a heat pump can move heat from the cool outdoors to warm a house; the pump may also be designed to move heat from the house to the warmer outdoors in warm weather. As they transfer heat rather than generating heat, they are more energy-efficient than other ways of heating a home.
