Engaging as Partners in Energy Efficiency: A Primer for Utilities on the Energy Efficiency Needs of Multifamily Buildings and Their Owners

The multifamily building sector presents a unique set of challenges and opportunities for utilities seeking to implement effective energy efficiency programs. To deliver successful programs, utilities must understand what motivates building owners to take part in these programs, as well as barriers that may prevent participation.This paper outlines the opportunities to meet energy efficiency goals with multifamily programs. It then describes the benefits that multifamily building owners gain from these programs, and the barriers they face to participation. The paper focuses on rental housing, because these buildings are owned by a single entity and form the largest sector of the multifamily housing market. The paper provides a framework to help utilities develop successful programs that maximize energy savings and create benefits for building owners, tenants, and communities. And lastly, the paper recommends nine program design considerations that can help attract multifamily building owners to utility energy efficiency programs

Modelling of a poultry shed

Tegel Foods is New Zealand’s leading producer and supplier of poultry products, providing an extensive range of quality poultry products to New Zealanders for over thirty years. Tegel is a fully-integrated poultry producer involved in breeding, hatching, feeding, growing, processing and marketing of chicken and turkey in New Zealand. The problem presented by Tegel was specifically to model the energy exchange between the chickens and their shed environment in order to better understand and control the shed climate and thereby maximize growth rate. A model for the heat production and water respiration rate of a typical chicken was developed, based on physical principles. A thermodynamical model of the whole chicken+shed system included the temperature of the external air, the internal air, the chickens, the litter, the concrete floor and the underlying soil. It also included the relative humidity (RH) of the external and internal air and the water flows into and out of the shed. Modelling of the shed environment’s inputs and outputs will be particularly valuable for continuing assessment of three fundamental inputs of economic importance: feed nutrient density in terms of energy formulation, heating in terms of gas/power usage, and heat removal via extraction fans. Optimisation of liveweight gain and feed conversion potential are the end targets

A comparison of some numerical methods for the advection-diffusion equation

This paper describes a comparison of some numerical methods for solving the advection-diffusion (AD) equation which may be used to describe transport of a pollutant. The one-dimensional advection-diffusion equation is solved by using cubic splines (the natural cubic spline and a ”special” AD cubic spline) to estimate first and second derivatives, and also by solving the same problem using two standard finite difference schemes (the FTCS and Crank-Nicolson methods). Two examples are used for comparison; the numerical results are compared with analytical solutions. It is found that, for the examples studied, the finite difference methods give better point-wise solutions than the spline methods

Greenhouse abatement policy: insights from the G-cubed multi-country model

The third meeting of the Conference of the Parties of the Framework Convention on Climate Change held in Japan last December was a lost opportunity to set a realistic policy framework for addressing climate change in the coming decades. A number of countries proposed targets for greenhouse emissions, to be reached by a target date. The outcome was a range of different targets for each country. Analysis with the G‐cubed multi‐country model suggests that fixed targets are a costly way to address climate change. The extent of potential cost suggests the agreement will eventually fail. A better way to address climate change is to focus on uniformity in policy instruments that deliver differentiated outcomes rather than focus on differentiated policy settings.Resource /Energy Economics and Policy,

The effects of fiscal consolidation in the OECD

Despite the current recession in many parts of the OECD, fiscal consolidation is likely in many OECD economies in the 1990s. The author asks: is fiscal consolidation in the OECD in a period of low growth a recipe for global stagnation? In particular, what effects are likely in developing countries? The author starts with an overview of cuts in the U.S. fiscal deficit proposed by the Clinton administration and the extent to which European governments must cut fiscal deficits between now and 1997 to satisfy deficit targets in the Maastricht Treaty. How changes in fiscal policy are transmitted within an economy and between that economy and the rest of the world depends on whether those changes lead to permanent or temporary changes in government saving; whether they are implemented through government spending or taxes; and whether the taxes fall on households or firms. The main channels of transmission are through changes in: agents'expectations about future taxes, interest rates, exchange rates, and economic activity. The author uses the MSG2 multicountry models to quantify the ramifications of those changes. He concludes, among other things, that fiscal contraction in the OECD will probably lead to slower growth over the next several years. But the current and likely paths of fiscal policy are such that deficit reduction programs may have stimulating effect in the short run, as long as future fiscal contraction is credible. And fiscal deficit reduction will probably increase long-run output in the OECD through its effects on savings and investment. Finally, growth in the developing countries (at least total growth) may not be impaired at all by fiscal consolidationin the OECD. The negative effects of fiscal contraction will occur through lower net exports of non-OECD economies. For developing countries with open capital markets, the initial reduction in demand through lower exports can be offset by the reduction in interest rates following an inflow of capital from the countries with contracting fiscal policy. A significant decline in real global interest rates is likely to increase growth in developing countries that are debt-constrained, either directly (through private capital inflows) or indirectly (by relaxing the balance of payments constraint, allowing more resources to be channeled to domestic investment needs).Economic Theory&Research,Economic Stabilization,Environmental Economics&Policies,Banks&Banking Reform,Macroeconomic Management

The East Asian crisis : investigating causes and policy responses

The authors identify as the primary cause of the East Asian crisis a fundamental reassessment of the profitability of investments in the region. They identify a number of secondary shocks as well, including interest risk premia, monetary expansion, and declines in output brought about by failures of the financial market. Unlike the Latin American crisis of the 1980s, the East Asian crisis did not reflect commodity price shocks, large changes in world interest rates, fiscal imbalances, or inflationary shocks. It involved large-scale borrowing abroad, but by the private sector rather than the government - andfor the normally well-regarded purpose of funding capital investment. It seems unlikely that terms of trade shocks or changes in exchange rates due to pegging to the dollar could, alone, have caused an adjustment crisis of this magnitude - although they could have helped trigger the crisis. More important, expectations of future growth in returns to the corporate sector began to fall. Declines in asset valuations caused major shifts in investment portfolios, and the consequences of asset market shocks were compounded by secondary shocks associated with the abrupt shift to floating rates, concerns about the credibility of government policies, weaknesses in financial sectors, and inadequacies in the mechanisms for corporate restructuring and liquidation. The authors use of forward-looking modeling framework to capture some of the major interactions between asset markets, output, and trade in the countries worst hit by the crisis. They find that the model is able to capture the main features of the crisis.Environmental Economics&Policies,Economic Theory&Research,Payment Systems&Infrastructure,Fiscal&Monetary Policy,International Terrorism&Counterterrorism,Economic Theory&Research,Environmental Economics&Policies,Economic Stabilization,Macroeconomic Management,Banks&Banking Reform

Agglomerate properties

Modelling of wet granulation requires the rate of agglomerate coalescence to be estimated. Coalescence is dependent on the frequency of collisions that occur, and the fraction of collisions which result in coalescence. The collision rate is a function of granulator kinetics and powder properties, while the coalescence success rate is dependent on factors including the Stokes number and particle geometry. This work investigates an aspect of the geometry by examining the distribution of liquid on the surface of agglomerates in the capillary state. Agglomerates are created by adding particles, one at a time, about a central tetrahedral arrangement of four primary particles. For a given agglomerate, the wetted fraction of surface area, defined as the wetness, is evaluated using an approximate fluid surface. Packing density and binder saturation parameters are incorporated into the model. Given a number of primary particles and the volume of binder in a particle, the agglomerate wetness is able to be estimated using computational geometry

A climate diplomacy proposal: carbon pricing consultations

The Doha climate talks in December 2012, wrapped up lines of negotiation that were begun years before in Bali. Negotiators resolved contentious questions about the future of the Kyoto Protocol and finally put the constraints of the Bali agenda behind them. Now they need turn to developing by 2015 a new agreement under the United Nations Framework Convention on Climate Change (UNFCCC) to cover the post-2020 period. In order to make concrete progress on climate policy there is a need to establish a Carbon Pricing Consultation (CPC) process, which would be a detailed, pragmatic, and ongoing discussion of the implementation details of domestic cap-and-trade and GHG taxes.Though carbon pricing generally been considered to be a national-level policy to be adopted at the discretion of individual governments the paper argues that a CPC process would provide an opportunity for negotiators, as well as the administrators of national pricing policies, to discuss how to induce, practically and efficiently, the broad economic shifts required to de-couple emissions and economic activity. This paper makes the argument for focusing on carbon pricing in the international negotiations and offers a way forward in that process
