7 multi-unit residential buildings
Detailed energy audits were provided for a portfolio of buildings, leading to retrofit measure recommendations aimed at saving 25% of energy and greenhouse gas emissions.
Pretium was engaged by GNPHC to prepare ASHRAE Level II Energy Audits for seven affordable, multi-unit residential buildings, all constructed in the 1990s. The audits included a comprehensive assessment of:
- base building components
- encompassing the building envelope
- HVAC systems
- electrical systems
- plumbing
- appliances
The primary focus was to evaluate energy consumption and greenhouse gas (GHG) emissions, and to identify viable Energy Conservation Measures (ECMs) to mitigate energy usage and corresponding emissions with a goal of achieving 25% emission reduction across the portfolio.
To deliver this project, Pretium completed the following measures:
GHG Reduction Planning
We work closely with our clients to develop customized strategies that minimize their carbon footprint while maximizing efficiency, durability, and cost savings. From comprehensive assessments to actionable implementation plans, we provide the guidance and tools needed to help our clients achieve their environmental goals.
ASHRAE Energy Audits (Level II)
Our team meticulously evaluates all energy-consuming systems within the building to identify opportunities for cost, energy, and GHG savings. Our audits are based on whole building energy models, making them eligible for most incentive programs. These audits are designed to help our clients unlock the full potential of their building’s energy performance.
Client Benefits
Pretium modeled optimal ECM bundles that aligned with each building’s capital replacement plan while determining retrofit pathways that ranged from 30 to 45% Greenhouse Gas reduction for each building.
Following the creation of accurate whole-building energy models, this project helped the client to achieve the following:
- Data-Driven Decision Making: Actionable insights derived from comprehensive energy audits to inform strategic decisions for energy efficiency improvements.
- Cost Savings: Implementation of identified ECMs to reduce operational costs associated with energy consumption.
- Environmental Impact: Reduction in GHG emissions to align with environmental sustainability goals and demonstrate GNPHC’s commitment to responsible stewardship.
