Case Study: Electrification of Heating for Multi-Building Campus

Project Overview

A university sought to improve energy efficiency and reduce operational costs by transitioning from an aging gas water heating system to a high-efficiency electric alternative. The upgrade aimed to lower carbon emissions, enhance system reliability, and align with the institution’s broader decarbonisation goals.

Quick Facts

  • Client: University

  • Location: Wellington, New Zealand

  • Scope: Replacement of gas water heating with electric hot water cylinders

  • Budget Outcome: In progress

  • Implementation Timeframe: In progress

  • Key Benefit: Reduced reliance on fossil fuels while lowering energy costs and emissions

Solution

  • System Upgrade: Installed high-efficiency electric hot water cylinders to replace outdated gas units.

  • Smart Controls: Integrated with the Building Management System (BMS) for optimised energy use.

  • Sustainability Impact: Reduced fossil fuel reliance, supporting campus-wide carbon reduction efforts.

  • Operational Efficiency: Improved heating system reliability and reduced maintenance costs.

Results

  • Energy Savings: Achieved 763,300 kWh in annual gas savings.

  • Carbon Emission Reduction: Reduced carbon emissions by 147 tonnes per year.

  • Return on Investment: Projected 2.35-year ROI.

  • Long-Term Savings: Projected savings of $1.1 million over the next 10 years.
