Multifamily housing represents a significant opportunity for energy efficiency, but the relationship between landlords, tenants and utilities can make implementing energy efficiency measures difficult. Our team works with building owners, property managers, tenants, government stakeholders and utilities to identify and implement energy efficiency measures including audits, efficient interior and exterior lighting, Energy Star appliances, weatherization and upgraded and energy efficient air conditioning or HVAC equipment.
Sample Multifamily Housing Energy Projects
- Galaxy Towers
- NYSERDA Multifamily Performance Program
- SBDI EEPS I – Common Area lighting
- Tarrytown Housing Authority
Representative Project: Galaxy Towers
Willdan is currently contracting with Comverge to perform energy audit and technical evaluation of Galaxy Towers – a three-building, 2M square foot multifamily residential complex located in Guttenburg, NJ. Through our comprehensive energy audits, Willdan identified potential energy efficiency measures and cost savings associated with upgrading the outdated/inefficient existing equipment, including: installing energy efficient lighting and lighting controls, upgrading rooftop AC units and window PTAC units, implementing a building management system (BMS), and installing demand control ventilation. If implemented, the proposed measures would reduce peak electric demand by 63 kW and electricity consumption by 136,708 kWh. This would save Galaxy Towers a total annual cost savings of over $30,000 and reduce their energy consumption by 14%, resulting in a 13 year simple payback period.
