“Once we sat down and started talking about pricing, that’s when 004the particular advantages of DEXTALL started to come into focus —it’s very appealing from that standpoint... We wanted not just to repurpose the building but to reposition it in the market.”

RICHARD WEINSTOCK

Vice Chairman and Senior Parnter at L+M, on choosing Dextall

The retrofit project was driven

by several core objectives:

Sustainability and Efficiency To significantly reduce energy consumption and the building's carbon footprint through the implementation of Dextall’s all-in-one insulation and cladding package. Implementing building envelope improvements to dramatically cut heating and cooling needs.

Committing to a 54% reduction in site energy use intensity and targeting carbon neutrality by 2030.

Tenant Comfort To enhance the living conditions for current tenants through superior acoustic and thermal performance of the new exteriors, and to improve access to natural light. Electrifying all loads in one building, transitioning from inefficient baseboard electric resistance heating to modern heat pump solutions.

006

Market Repositioning To transform the building’s aesthetic appeal, aligning The Heritage with contemporary design standards and repositioning it in New York’s competitive real estate market.

Minimal Disruption To ensure that the retrofitting process causes minimal inconvenience to the existing tenants, maintaining their quality of life during the construction phase.

inspired, focusing on envelope improvements and full electrification.

Empire Building Challenge Approach The Heritage's retrofit strategy incorporates the Empire Building Challenge's holistic approach to decarbonization, focusing on phased, strategic roadmaps tailored to the complex's specific needs. This includes major envelope improvements, the installation of packaged terminal heat pumps, and full electrification of one building within the complex.

008 Design and Materials A "hybrid" retrofit approach was selected, combining Dextall’s D-Wall 1500 product with an Exterior Insulation Finishing System (EIFS) to address the 001 structural challenges of the aging facade. This solution aims to eliminate fossil fuel usage, leveraging state-of-the-art heat pump water heaters and electric laundry dryers. This hybrid approach was tailored to overcome the structural challenges of the aging facade while adhering to strict budget constraints.

Construction Approach with Tenants in Mind

009

001

1

Planning: Meticulous preparation to minimize impact on tenants.

2

Installation of Temporary Walls: Ensuring safety, noise reduction, and environmental control.

3

Panel Installation: Efficient strategy allowing for the installation of approximately 10 panels per day.

Given the logistical challenges of executing a major retrofit with tenants in place, the project utilized a vertical installation strategy for the new unitized wall panels. This method minimized disruption and ensured that the building remained secure and weatherproof throughout the renovation.

010

Planning and Preparation The first step in the retrofit process involved meticulous planning to ensure that the daily lives of the hundreds of tenants at The Heritage were minimally disrupted. This planning phase included logistical strategies for installing temporary walls inside apartments, ensuring safety protocols, and scheduling construction to minimize noise and other disturbances.

011

Installation of Temporary Walls 001

A key feature of the construction process at The Heritage was the installation of temporary walls within the apartments. These walls were erected as a physical barrier between the tenants' living spaces and the construction zones. Designed to be sturdy yet easily removable, these temporary structures served multiple purposes:

throughout the retrofitting process.

012

Demolition and Panel Installation

With the temporary walls in place, the construction team began the careful demolition of the existing facade. This phase was carried out with precision to avoid damaging the building's structural integrity and to prepare the exterior for the new prefabricated panels.

The installation of Dextall’s prefabricated panels was a critical phase of the construction process. Designed for efficiency and minimal on-site labor, these panels were brought to the site ready to be installed, equipped with all necessary insulation, windows, and cladding. The construction team utilized vertical runs for the installation, a strategy that allowed for the methodical replacement of the facade, one apartment at a time. This approach was particularly advantageous for a few reasons:

Challenges and Solutions

Maintaining water and air tightness with temporary vertical closures Logistical planning for material delivery to support the vertical 001 installation strategy.

“Integrating modern aesthetics with advanced energy-efficient technologies was a challenging yet rewarding task. The results speak for themselves in the improved quality of life for the tenants.”

DAVID ASH

L+M Developers

014 To address this, Dextall designed temporary vertical closures that could be quickly installed and removed as the work progressed, ensuring that the building remained protected against the elements.

Another challenge was the logistical complexity of delivering materials in a specific sequence to accommodate the vertical installation strategy. The project team developed a detailed logistics plan that included precise timing for material delivery and storage solutions to keep the construction site organized and efficient.

TESTIMONIAL

AFTER

017 Living at The Heritage after the renovation has been truly transformative. The difference is staggering – from the gloomy, outdated feel to the stunning new look of the building, it’s like night and day. Before, the old windows barely allowed any light in, and the narrow bedroom windows felt like something out of a prison cell. Now, everything has changed. The apartment feels cozy and warm, with no more pesky drafts to contend with. This entire transformation has uplifted not just my living space, but my spirits as well.
