Net Zero Energy Building Design in High Density Urban Cities

Net Zero Energy solutions suitable for urban settings will be increasingly important but there are unique policy and technical challenges to implementing these solutions in large urban buildings in hot and humid climate. Addressing these concerns could open up the possibility of achieving Positive Energy Low Rise, Zero Energy Medium Rise and Super Low Energy High Rise Buildings in the near future.

How do we overcome limited site and roof spaces for renewable energy in urban cities? How do we drive passive design for free cooling in high density environment? How do we reduce the consumption level of plug loads leveraging off the IoT? How do we use the advanced modelling approach to create designs that can achieve Net Zero Energy and then manage the delivery process so that Net Zero Energy performance? How do we move from demonstration phase projects to successful solutions for all buildings?

Uncovering a Building’s Heartbeat Sensormatically

While energy use is a key component in building management, it is important that resource use not overshadow a building's purpose: to provide an adequate (or even enhanced) space for humans or machines to operate. Managing this interdependency between comfort and energy is not easy, but it's essential for high performance spaces as changing occupant comfort demands can consume significant amounts of energy. While optimizing each in isolation is simpler, the results could lead to less than ideal outcomes.

As managers seek to optimize both energy use and comfort, well-placed sensors and data collection systems can provide objective, useful, and actionable information. Building energy meters separated by panel, circuit, or receptacle are useful in determining, where, when, and how energy is being used. Comfort can be divided into visual, thermal, acoustic, and air quality categories. Sensors are able to measure each category in order to determine which aspects of comfort might be insufficient. Ultimately, the sensor data can be analyzed to establish linkages and tradeoffs and can lead to solutions that optimize both factors. Four different projects are presented to demonstrate how energy and comfort can be balanced at a building, campus, and program level.

Collaborating for Sustainability in Leased Space

Energy efficiency and sustainability have multiple benefits for commercial building occupants. Now, many forward-thinking corporations are employing sustainability tactics and focusing real estate strategy to attract and retain top talent, minimize operating expenses, and drive occupant comfort, health, and productivity. New technologies, a rapidly developing business case, and increasing research are making it easier for more organizations, across sectors, to leverage sustainability to capitalize on the same trends that are rapidly becoming the norm in top-of-the-market, class-A real estate. However, as tenants progress from site selection to occupancy, it becomes increasingly difficult to invest in sustainability. Tenants and landlords should collaborate early to maximize sustainability throughout the life of the tenant-landlord relationship.

In 2015, Congress passed the Energy Efficiency Improvement Act, which directed several federal agencies, including EPA and DOE to identify and employ appropriate strategies to incentivize and engage commercial landlords and tenants to collaborate towards energy efficiency. This panel will discuss the opportunities that legislation will create for tenants and corporate occupiers to leverage energy efficiency and sustainability to meet corporate social responsibility goals and earn public recognition for their success. Panelists will also introduce a variety of tools and resources that are currently available to the market.

Green, Complete and Smart: Build Green vs. Grey

Communities are turning to innovative stormwater management solutions to solve local and regional stormwater challenges. For example, in the nation’s capital, DC agencies recently modified a plan that predominately relied on grey infrastructure to instead partially replace the grey infrastructure with green infrastructure in targeted existing impervious areas. These green installations will serve to mitigate flooding and stormwater issues to the same capacity but with many more environmental and community benefits.

The panel will discuss stormwater challenges through several examples located throughout the country, and the impact of vegetated systems to manage stormwater in local and regional jurisdictions. One example that will be discussed is The American Society of Landscape Architects (ASLA) proposed Green Street Demonstration Project in the Chinatown neighborhood of Washington D.C. where the ASLA headquarters are based. The project seeks to serve as an example for such green, complete, and smart street design. The plan transforms an underperforming street corridor into a showpiece of both green infrastructure technologies and complete street approaches.

Your Zero Net Energy Building May Destroy the Grid

With emerging standards requiring different forms of Zero Net Energy and aggressive owners developing ZNE buildings already it's an important time to look at the potential impacts net metered buildings can have on the historic grid structure and operations. High penetration of renewable energy can destabilize the grid operations and cause havoc for grid operators.

We'll provide a detailed discussion of the different definitions of ZNE and how they impact design and interaction with the grid. We'll outline current issues with high penetration of renewables on Hawaii's grid structure and how they may apply to ZNE building design for larger grid systems. We will provide building strategies that can enhance ZNE building design participation with the grid such as battery storage with renewables, demand response, thermal energy storage, and controls. Finally the team will outline ongoing changes to the grid structures and enhancements needed to prepare the grid for true ZNE buildings on a mass scale.
