HVAC and Risk from Airborne Hazards

Interest in protection of building occupants from airborne chemical and biological agents was strongly stimulated by several terrorist incidents early in the 21st century. The discussion generated by these incidents brought to the forefront the concept of formal risk assessment for airborne hazards, which few building designers or owners undertake. Over time, the discussion of HVAC security has declined without significant changes having been made to either design requirements or procedures, yet the issue remains and is more important than is generally acknowledged, since accidental exposures have the potential to be just as harmful as intentional ones. This presentation provides an overview of the key issues relating to protection of building occupants from chemical and biological releases including: HVAC system and building characteristics that affect exposure, the spectrum of available countermeasures and their characteristics, risk assessment processes, and metrics for describing the level of risk and degree of improvement achieved by a risk reduction strategy.

Intelligent Buildings – Technology is changing what is possible in the built environment

There is a lot of buzz around Intelligent, or Smart, Buildings, but what is an Intelligent Building? This presentation will examine the answers to this question and how you can put your building on its path to a “higher education”.

Advancements in technology have given the engineer the ability to aggregate and share data across disparate systems thereby creating opportunities to increase energy and operational efficiencies, improve occupant comfort, safety, productivity, and enrich the visualization capabilities for the organization’s numerous internal and external stakeholders. The intelligent building platform will result in a more efficient, secure and productive asset that has the capacity to continuously improve over its lifetime.

Energy efficiency in residential buildings

ASHRAE 90.2 is a standard for Energy-efficient design of Low-Rise Residential buildings. It provides minimum design and construction requirements for Low-Rise Residential buildings and their systems. In Table 4.1-Prescriptive Requirements by Component, ASHRAE 90.2P-APR Draft provides values for building envelope components such as Wall, Roof, and Glazing and Energy efficiency for air-conditioning systems for various climatic zones.
It is often found that the values provided in Table 4.1 are not pertinent to the Middle Eastern regions because of its different geographical locations, climatic conditions, cultures, and building practices. Certain values are also often found to be less stringent than the local authority regulations and standard practices prevailing in the region.

The objective of this Technical paper is to analyse and assess some of the prescriptive requirement values in ASHRAE 90.2 such as building envelope components Wall, Roof, Glazing and Energy efficiency of air-conditioning systems, using Building Energy Modelling Simulation techniques for different regions in the Middle East.

It has been found that the Building Envelope forms a significant portion of the cooling or heating loads for low-rise residential buildings and therefore a major percentage of energy consumption for the air-conditioning systems. Optimising the building envelope values can provide substantial savings in energy. Similarly, the Energy Efficiency of the air-conditioning systems is a significant factor of energy consumption in the region. Optimising the Energy efficiency of air-conditioning systems can also provide substantial savings on energy.

A comparative analysis is made for Thermal Conductivity (U) values of Walls, Roofs, and Glazing, along with Solar heat gain coefficient (SHGC) for glazing and Energy Efficiency of air-conditioning systems from the Building Energy Modelling simulation results, to analyse the energy consumption and potential energy savings and obtain optimised values for these parameters relevant to the Middle Eastern region.

Comparative analysis is made using the ASHRAE 90.2 values against corresponding values in Local regulations such as Ministry of Electricity & Water (MEW) Kuwait, Saudi Building Code (SBC), and other local regulations and prevailing local standard practises in the region.

The comparative analysis is carried out for different regions in the Middle East which includes Kuwait City, Riyadh, Doha and Beirut regions to form a wider spectrum of climatic regions.

The optimised values of building envelope components and energy efficiency of systems can significantly improve and enhance the energy performance of the building and help in sustainable and efficient designs of buildings in the Middle Eastern Region.

Ozone and Climate Friendly Urban Transformation via Renewable Energy Sources, Energy Efficiency, Modeling Predictive Control and Smart Grids

An extremely intensive migration is under way around the world causing an enormous growth of cities and their energy demand and a series of social, political and economic problems. In order to conduct urban transformation and reach sustainable social and economic development, it is necessary to transform urban with suburban and rural areas integrally to enable a reliable approach to harmonious development by reducing disparities in living conditions, which includes increasing accessibility to energy supply, suppressing pollution and reducing CO2 and other greenhouse gas emissions and supporting growth of clean renewable energies use. Urban and rural sustainable clean energy generation potential is different. In rural areas, mainly in all countries around the world, distributed houses can be RES integrated refurbished to be able to produce more energy, particularly electrical, than they are using. Rapidly growing slums could also contribute to sustainable urban-rural (rurban) energy system transformation.

The presentation outlines technical advances in BPS and modeling predictive control for integrated optimization of the energy efficiency and cost-effectiveness of renewable energy sources (RES) implementation, as well as its crucial role in the modeling predictive based smart-grid control of RES based distributed energy co- and tri-generation for “high performance” Zero CO2 emission, Energy+ and healthy – ozone and climate friendly settlements and cities. The presentation will encompass: new technologies and research strategies in energy plus buildings, the most recent ICT approaches to cities’ sustainability, seeking higher density buildings solutions, developing Smart Grids as integrated Total Performance Control of buildings at neighborhood and district level, developing new monitoring system, taking in account weather extremes including catastrophic events and global warming evidence, buildings’ and settlements resilience relevant features, as well as including houses components, effectiveness and efficiency of implementing harmonious integration of buildings structures, thermal mass passive/active solar with HVAC and other technical systems.

Addressed will also be the Solar Decathlon worldwide university competition, with the reference to the Smart Grids integrating EnergyPlus buildings and demonstration of their practical performance of optimization using in synergy developed unique modeling and measuring/monitoring system (launched Trans-disciplinary Synergetic Modeling and Monitoring Program at the SDE 2014 in Paris). As a result, the produced treasure of data and gained experience can serve as a cradle for foundation of corresponding Living Global Network and specific ICT Platform organization. Such Living Lab World Network with corresponding ICT web-based platform could as a Hub (could it be ASHRAE?) connect numerous worldwide spread interested stakeholders, including series of R&D Labs on EnEff-RES/HVAC integrated buildings, sustainable buildings construction and HVAC and other builldings technical systems (lighting, electronic-electrical, energy mix supply technologies and engineering industries, etc.). In addition it is necessary to plan technically testing of the integrated buildings/HVAC and RES technologies, systems and equipment (in commercial development) before launching their industrial scale production and implementation.

Impacts of Carbon Reduction Plans in U.S. Mega Cities

Many cities in the United States have created climate action plans with tangible goals for carbon reduction from buildings. This presentation focuses on the initiatives set forth by Cities including enhanced energy codes for new buildings and benchmarking and disclosure policies for existing buildings. An overview of results from recent reports tracking reduction goals from mega cities including New York, Chicago and Seattle will be presented as well as next steps for how they are changing their initial plans based on current results. The presentation will also discuss how ASHRAE Standards 90.1, 189.1 and 100 are being incorporated by Cities for energy policy as well as the Building Energy Quotient for building labeling.
